Anders et al. Knee Surg Sports Traumatol Arthrosc. These eventually would form fibrocartilage at the defect. High-impact activities, such as running and jumping, should be avoided until 6 to 12 months after surgery. Outcomes following surgery are variable and thus treatment strategy has to be tailored to every patient based on specific factors. Osteochondral defects of the talus (OCD) are a well-established pathology within the ankle. A systematic review of 52 studies including 1236 primary OLT by Dahmen et al. transplantation surgery fo r osteochondral lesions. 1980;62:646–652. [24], Operative treatment is indicated for OLT that have remained symptomatic even after a conservative trial for 3–6 months. Osteochondral Allograft transplantation for knee lesions after failure of cartilage repair surgery. [2] The rationale is to form a hyaline cartilage at the defect from pluripotent cells instead of fibrocartilage that forms after microfracture alone. Introduction. Because of the relatively high cost of ACI and the knee morbidity seen in OATS, we conclude that BMS is the treatment of choice for primary osteochondral talar lesions. Choi et al. This joint permits much of the up (dorsiflexion) and down (plantarflexion) motion of the foot and ankle. They are most commonly … of the talus but at the cost of a hi gh rate of. Berndt and Harty classification is the staging system that is widely employed for describing OLT on plain radiographs. found PRP as an adjunct to arthroscopic microfracture for the treatment of OLT resulted in improved functional score status at an average follow-up of 16.2 months. [20] Either fixation or excision is recommended for acutely displaced lesions while conservative treatment is the initial treatment indicated for all acute undisplaced lesions and other symptomatic OLT presenting late. INTRODUCTION. Donor site morbidity and the need for a medial malleolus osteotomy remain its major disadvantages. FIGURE 71-1 Osteochondral lesion of the talus. All of the bones are a complex group of living organs that are composed of multiple cells, protein fibers and a range of minerals. Among the OLT, up to 94% of the lateral lesions are said to be secondary to trauma while only 62% of medial lesions are post-traumatic. Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. Arthroscopy. Commonly, multiple cylinders have to … [3] This review aims to elucidate the historical aspect of the disease, etiopathogenesis, classifications, diagnosis, and treatment to assist in day-to-day clinical practice. [28], The prognostic factors that determine the success of microfracture are listed in [Table 3]. There are a number of treatment options. described the classifications of OLT based on CT and MRI, respectively. The skeletal system is made up of all the joints and bones in the body. The major advantages of arthroscopic surgery are that it is associated with a faster recovery due to less pain and earlier mobilisation of the ankle than after conventional open surgery. With an MRI, the ligament structures, tendons and cartilage of the ankle can be examined and analyzed. Microfractures, are often considered the first-line surgical treatment option due to the low costs and ease of the technique ( 34 - 38 ), while ACI is rather reserved as a salvage procedure ( 39 - 41 , 45 ). J Bone Joint Surg Am. Current treatment options include minced bone and cartilage paste, 1 mosaicplasty, 2 allogeneic osteochondral transplantation, 3-5 combined bone and chondrocyte transplantation, the so-called sandwich technique, and synthetic osteochondral implants. Osteochondral defects of the talus (OCD) are a well-established pathology within the ankle. Although the short- to mid-term clinical outcomes are generally good, the quality of regenerated cartilage is unpredictable. Foot Ankle Int. [5] The sole indication for operative treatment at presentation is an acute lesion with displacement. [51], This technique combines microfracture with either autologous iliac crest bone marrow aspirate concentrate (BMAC) or PRP secured to the defect using a collagen scaffold/fibrin glue in a single stage [Figure 3]. Fibrocartilage is predominantly made of Type I collagen which is structurally and biomechanically inferior to hyaline cartilage. 2020 Feb 9;10(2):e033850. A full diagnostic arthroscopy is performed, and then attention is turned to the osteochondral defect. reported retrograde drilling and autogenous bone grafting to be an excellent technique in their review of 41 patients of OLT with an intact overlying cartilage with good functional and radiological outcome. Verhagen RA, Struijs PA, Bossuyt PM, van Dijk CN. This is a relatively newer technique that employs transfer of particulated juvenile cartilage pieces with their native extracellular matrix harvested from deceased donors aged from newborns to 13 years. Orthopade. [19] Commonly used classifications are summarized in [Table 1]. 2020 Jul;14(2):64-71. doi: 10.5704/MOJ.2007.014. and Hepple et al. [Diagnosis and treatment of osteochondral lesions of the talus]. These lesions pose a diagnostic challenge to the attending clinician due to lack of specific clinical signs and lack in consensus regarding treatment makes the management aspect controversial.

[46] This harvested cartilage is then transferred to the area of defect and secured using fibrin glue. Les lésions du cartilage articulaire du genou sont fréquentes. Patients present with spectrum of non-specific complaints including of pain on weight-bearing, swelling, stiffness, and occasionally locking sensation at the ankle joint. [45] Due to high rates of reoperation and failure, it is necessary to opt for other less morbid techniques initially, keeping this technique of osteochondral allografting as a bail out procedure in failed cases. [15] Although it provides good visualization of the cartilage, it tends to overestimate the extent of the subchondral lesion due to the associated marrow edema. Initial x-rays are taken to check the alignment of the foot and ankle, as well as look for any bone damage. -, Baker CL, Jr, Morales RW. After a longer follow-up, some patients showed that the beneficial results were not maintained, indicating the deterioration of the … The first description of osteocartilaginous loose bodies in the ankle, attributed to trauma, was given by Monro in 1738. [25] Useful algorithm describing the indication for each procedure is outlined in [Figure 1]. [31] The reported incidence of complication rate varies from 0 to 14% with superficial peroneal neuropathy and portal site pain cited as the most common complications. By the mosaicplasly technique, osteochondral grafts are transplanted from areas of little weight bearing at the outer limits of the trochlca to the focal lesion in the same knee. © Copyright 2020 – Journal of Arthroscopic Surgery and Sports Medicine – All rights reserved.Published by Scientific Scholar on behalf of Indian Arthroscopy Society. Abstract: The objective of this study was to assess the outcome of osteochondral allograft (OCA) transplantation as a salvage procedure after various cartilage repair surgeries. Box 22660, 1100 DD, ... Because of the relatively high cost of ACI and the knee morbidity seen in OATS, we conclude that BMS is the treatment of choice for primary osteochondral talar lesions. Guney et al.  |  Because of the relatively high cost of ACI and the knee morbidity seen in OATS, we conclude that BMS is the treatment of choice for primary osteochondral talar lesions. … [26] Furthermore, the quantity and quality of fibrocartilage formed may vary. Table 3 below presents the base-case deterministic results when using an OCA graft price of £3892.50 (€4174) based on costs in Spain. [3] Conservative treatment mainly consists of rest, avoiding sporting activities, cast immobilization with or without NSAIDs, and intraarticular injection of platelet-rich plasma (PRP) and hyaluronic acid (HA). [14] Provocative tests such as anterior drawer test should be performed and compared to the unaffected side to evaluate the associated instability. Osteochondral transplantation of autologous graft for the treatment of osteochondral lesions of talus: 5- to 7-year follow-up. Clipboard, Search History, and several other advanced features are temporarily unavailable. Plain radiography is the initial investigation of choice in a clinically suspected case of OLT. Particulated nature gives mobility to the chondrocytes to escape from the minced pieces and form a hyaline cartilage like matrix in the area of the defect. Osteochondral lesions of the talus are injuries to the cartilage in the bone inside the ankle joint. Despite the advantages, the reported failure rate is 40% with lesions of area >125 mm2 and male sex associated with significantly higher risk of clinical failure. Once the piece has broken off, surgery is almost always necessary. IN) to treat patellar lesion. doi: 10.1016/s1083-7515(02)00064-5. HA is known to reduce inflammation in the joint while simultaneously substituting joint fluid. In some rare cases, osteochondral lesions can occur for no apparent reason. Ferkel’s grading is the most commonly employed grading system on arthroscopy. that included four studies concluded that PRP used in conjunction with microfracture results in better pain and functional improvement than microfracture alone. The blood supply to the talus is not as rich as many other bones in the body, and as a result injuries to the talus sometimes are more difficult to heal than similar injuries in other bones. Furthermore, PRP group had significantly better outcomes than the HA group. [44] A systematic review by Richard et al. The tibia and fibula bones sit above and to the sides of the talus, forming the ankle joint. There are only a few recent studies that have reported the outcomes following non-operative management. Foot Ankle Spec. This commonly occurs after an ankle sprain where the two bones hit against each other, causing a piece of cartilage and bone to chip off inside the ankle. Actual surgical treatments for osteochondral lesions and early knee osteoarthritis seem to be promising. Med Sci Monit. [13] All these factors make the talus prone for developing osteochondral lesions. NIH In this video, I discuss the types of surgery and how you might recover from those surgeries. Recovery and surgery for an OCD lesion of the knee. We use cookies to ensure that we give you the best experience on our website. If structured rehabilitation is unsuccessful, then … The purpose of this study is to evaluate the outcomes of lesions treated with osteochondral allograft transplantation. This is often referred to as a chip inside your ankle joint. An osteochondral lesion of the talus is often a difficult problem to treat. doi: 10.2106/JBJS.E.00033. Long-term follow-up. [2] The allografts used are either fresh allografts which have to be used within 28 days or fresh frozen allografts with relatively less chondrocyte viability. Clinical Outcomes of Osteochondral Lesions of the Talus With Large Subchondral Cysts Treated With Osteotomy and Autologous Chondral Grafts: Minimum 2-Year Follow-up and Second-Look Evaluation. [48], It is a 2-stage procedure where in hyaline cartilage is harvested either from the neck of the talus or non-weight portion of the knee joint, this cartilage is then cultured to grow chondrocytes which are implanted back to the area of defect and secured using a periosteal flap as a second-stage procedure. Clinical examination may reveal effusion at the ankle, tenderness over the talus on palpation, decreased range of motion, and pain on ankle dorsiflexion and inversion. Surgical treatment of transchondral talar-dome fractures (osteochondritis dissecans). [2,39] Flynn et al. Thus, treatment should be individualized to every patient, with adequate counseling regarding the outcomes and associated complications of that technique. In both studies magnetic resonance imaging (MRI) was performed prior to open reduction and internal fixation (ORIF). Furthermore, improvement was better when PRP was used as an adjunct to microfracture than a conservative intraarticular injection of PRP. INTRODUCTION. in 1986. A review was performed of 30 athletes with 31 OLTs that were refractory to marrow stimulation or … Much of this bone is covered with cartilage. 1 Department of Orthopaedic Surgery, Academic Medical Centre, University of Amsterdam, P.O. Operative techniques can be broadly classified as cartilage repair, regeneration, and replacement techniques [Table 2]. 2002;23:381–389. This option is useful for large OLT with extensive subchondral cysts. [40] A retrospective analysis of 131 patients suggested that though all patients returned to sporting activity, they engaged in fewer, less frequent sporting activities post-OATS treatment.[41].  |  Recommended indications include a symptomatic patient with size of the lesion at least 1.5 cm in one dimension or a patient who had a failed marrow stimulation technique. Osteochondral lesions are caused by trauma, osteochondritis dissecans (OCD), or osteonecrosis. Cystic lesions require curettage and penetration of the calcified wall of the cyst. However, if we cannot get insurance approval for this material due to cost (about $7,000), we will use the aforementioned BioCartilage product instead. Osteochondral autograft transplantation is used to address small to medium defects (1–4 cm 2), often with associated bone loss. [10], Most OLT are secondary to trauma, with up to 50% of ankle sprains resulting in some grade of cartilage injury. [30], Polat et al. [] This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. Autologous osteochondral grafting for talar cartilage defects. This initial evaluation often leads to a broad differential diagnosis including ankle synovitis, impingement, occult fractures, and early ankle/subtalar arthritis.[2]. reported good pain relief and function in a prospective study of 10 patients with a long follow-up of 13 years and concluded that MACI should be considered for osteochondral lesions that fail initial microfracture treatment. If you continue to use this site we will assume that you are happy with it. Seven studies described the results of non-operative treatment, 4 of excision, 13 of excision and curettage, 18 of excision, curettage and bone marrow stimulation (BMS), 4 of an autogenous bone graft, 2 of transmalleolar drilling (TMD), 9 of osteochondral transplantation (OATS), 4 of autologous chondrocyte implantation (ACI), 3 of retrograde drilling and 1 of fixation. [2] Lee et al. [21] Weigelt et al. Availability of fresh donor allografts and the associated cost is also a concern in developing countries. eCollection 2020 Jul. [22], Injection therapy alone with PRP or HA has also been attempted in the treatment of OLT. Finite Element Analysis of the Effect of Talar Osteochondral Defects of Different Depths on Ankle Joint Stability. Retrograde drilling and fixation scored 88 and 89%, respectively. Fifteen patients underwent mosaic osteochondral transplantation to treat a talar osteochondral defect lesion, with 11 patients available for follow-up. Chahla et al. Bai L, Guan S, Liu S, You T, Xie X, Chen P, Zhang W. Orthop J Sports Med. 2020 Aug 21;26:e921823. [8,9] There have been numerous changes to the terminology of these lesions since the first description, however, the term “osteochondral lesions of the talus” (OLT) is generally preferred. They are most commonly associated with ankle trauma and wh… Please enable it to take advantage of the complete set of features! 1999;15:197–202. These repetitive injuries may result in microtrauma in an already vulnerable bone with sparse vascularity causing OLT. Limited, Coimbatore, Tamil Nadu, Department of Orthopedics and Spine surgery. 2013 Jun 5;95(11):1045-54. doi: 10.2106/JBJS.L.00773. In both studies magnetic resonance imaging (MRI) was performed prior to open reduction and internal fixation (ORIF). J ISAKOS. Series shows the case of a 25-years-old man, a sports and physically active patient, with chronic ankle pain, a lateral talus osteochondral lesion (OCL), and chronic ankle instability. A treatment gap exists for patients with lesions not suitable for arthroplasty or biologic repair or who have failed prior cartilage repair surgery. Furthermore, it is hard to figure out why some osteochondral lesions, small or large, are painful and some are not painful. There is limited understanding of cartilage damage and its repair. Arthroscopic microfracture is the most frequently performed procedure for an osteochondral lesion of the talus (OLT) [1,2,3,4]. The main advantage of this procedure is that these harvested plugs are made up of hyaline cartilage (Type II collagen), restoring the articular cartilage to near normal. Together with the newer techniques OATS and ACI, BMS was identified as an effective treatment strategy for OCD of the talus. [17,18] Arthroscopy remains the gold standard as it allows direct visualization, probing of the lesion to assess the stability of the overlying cartilage and also accurately assess the extent of the lesion. Because MRI may overdiagnose or overestimate the … transplantation surgery fo r osteochondral lesions. This is possible due to less damage to the surrounding skin, ligaments and tendons. [1] Klammer et al. Scranton Type V Osteochondral Defects of Talus: Does one-stage Arthroscopic Debridement, Microfracture and Plasma Rich in Growth Factor cause the Healing of Cyst and Cessation of Progression to Osteoarthritis? 2005;26:583–589. Growth factors contained in PRP can facilitate cartilage repair by stimulating matrix formation and increasing chondrocyte proliferation. A history of ankle trauma/recurrent instability is to be elicited as OLT are associated with ankle instability. Both non-operative and operative modalities have been described for the treatment of OLT. [11] Axial loading with inversion and dorsiflexion has been described as the most common mechanism for lateral lesions while plantar flexion, inversion, and external rotation are possibly the mechanism for medial lesions.[10]. The talus is the bottom bone of the ankle joint. [2] This technique is effective in treating large cystic lesions even up to 6 cm2 with favorable outcomes reported. 2020 Jul 28;8(7):2325967120937798. doi: 10.1177/2325967120937798. Osteochondral allograft reconstruction (OCA) is highly cost-effective [30, 31] but the procedure is limited by the scarcity of fresh grafts and in some countries use is restricted by law [11, 46]. in their review highlighted the paucity of long-term high-level studies regarding usage of BMAC in OLT with most evidence coming mainly from retrospective studies. Surgical treatment is indicated after a failed conservative trial, larger lesion and can be broadly split into cartilage repair, replacement, and regenerative strategies. [23] A level-II randomized study conducted by Mei-Dan et al. In 90 percent of patients, grafts survive at least 10 years. [] Although majority may be associated with trauma, some may develop insidiously. Osteochondral cylinders are harvested from lesser marginal weight-bearing areas of the knee joint and press-fitted into the prepared defect. [53], In summary, outcomes following surgery are variable and thus treatment strategy has to be tailored to every patient depending on specific factors. Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. Surgery to treat an osteochondral ankle lesion is a series of steps that usually starts with the least invasive technique, an arthroscope, as the last step of diagnosis before your surgeon progresses with whatever needs to be done to repair the top of your talus. Background: The incidence of osteochondral lesions (OCLs) in association with displaced ankle fractures has only been examined in two previous studies. Osteochondral lesions (OCLs) are focal articular injuries of the subchondral bone and the cartilage with a multifaceted cause (trauma, ligament instability, ischemic necrosis, malalignment, endocrine diseases, and others). J Bone Joint Surg Am. [27] Toale et al. Osteochondral allograft transplantation has been performed for the past 50 or more years with several studies demonstrating satisfactory outcomes. Hence, MRI is the investigation of choice in a clinically suspected lesion with negative radiographs while CT remains the preferred investigation for pre-operative planning with a positive plain radiograph as it better demonstrates the subchondral area of the lesion. Epub 2014 Oct 19. OCD lesions are also called osteochondritis dissecans or osteochondral fractures. For each treatment strategy, study size weighted success rates were calculated. Osteochondral lesions of the talus encompass important clinical conditions encountered in day-to-day practice. USA.gov. Autologous chondrocyte transplantation for treating cartilage defects of the talus. described the natural history of OLT in 43 patients who opted for conservative treatment with a minimum follow-up of 2 years. The knee and the ankle joint are the most commonly involved joints for OCLs in the lower extremity. Surgical technique should be mainly chosen depending on the status of the overlying cartilage, size, and containment of the lesion. Une lésion localisée ou diffuse est ainsi retrouvée chez deux tiers des patients en cas d’exploration arthroscopique d’un genou douloureux.1–4 Les faibles capacités de cicatrisation du cartilage au-delà d’une certaine taille sont expliquées par sa nature avasculaire et les facultés très limitées de régénération des chondrocytes.5–7 Les lésions cartilagineuses sont des facteurs de risque d’arthrose post-traumatique.8,9 De nombreuses technique… The cost-per-point change in functional outcome score was $200.59 for MFx, $313.84 for OAT, and $536.59 for ACI-1. concluded OATS to be an effective treatment strategy even for large OLT with MOCART scoring showing good structural integrity of the graft at mean follow-up of 24.8 months and good functional outcomes irrespective of a prior microfracture or concomitant procedure. Osteochondral autograft transfer system (OATS), Particulated juvenile cartilage allograft transfer (PJCAT), Autologous chondrocyte implantation (ACI), Matrix-induced autologous chondrocyte implantation (MACI), I: Cystic lesion at the dome with intact roof on all sides, Medial/lateral lesions, subchondral cysts. [23] As far as BMAC is concerned, varying degrees of beneficial effects have been reported in different studies when used as an adjunct to surgical procedures. Operative treatment of osteochondral lesions of the talus. [49], This is a second-generation technique that employs a collagen matrix instead of a periosteal sleeve to secure the chondrocytes. Classification of operative techniques for OLT. [5] In 1959, Berndt and Harty were the first to describe the pathogenesis of osteochondral lesions post-trauma. Rationale of conservative treatment is to offload the affected area for resolution of bone marrow edema and to facilitate healing of the detached cartilage. Although outcomes of most of these techniques are promising, it is hard to recommend one procedure over another due to lack of comparative analyses. in 1984 emphasized that these lesions should not be called as osteochondritis dissecans but be grouped under a broader term “osteochondral lesions of the talar dome.”[7] The arthroscopic treatment of these lesions was first described by Parisien and Pritsch et al. [50] Kreulen et al. Fifty-two studies described the results of 65 treatment groups of treatment strategies for OCD of the talus. The next day did MRI scans and X-rays and there was the release of free bone fragment in the knee joint and with apparent origin in the former osteochondral lesion. Osteochondral lesions of the talus (OLTs) continue to be a challenge for the treating surgeon, especially when lesions are refractory to marrow stimulation techniques. Treating osteochondral lesions of the talus can pose challenges and delayed diagnosis due to late presentation after an ankle sprain. Get the latest public health information from CDC: https://www.coronavirus.gov, Get the latest research information from NIH: https://www.nih.gov/coronavirus, Find NCBI SARS-CoV-2 literature, sequence, and clinical content: https://www.ncbi.nlm.nih.gov/sars-cov-2/. 2016. [2], Microfracture is a technique of perforating the subchondral bone to allow the progenitor cells from the bone marrow to infiltrate into the lesion [Figure 2]. in their systematic review of 15 studies with a mean follow-up of 72 months also highlighted surface damage in 76% of patients on follow-up MRI that could be a harbinger for long-term problems. Osteochondral Lesion Anatomy. Effect of autologous adipose-derived mesenchymal stem cell therapy in the treatment of an osteochondral lesion of the ankle. OLT encompass a wide variety of disorders that are both difficult to diagnose and also to treat with varying functional outcomes. OATS uses bone-cartilage cylinder grafts from a non-weight bearing portion of another joint and transplants these on the site of the defect. MRI is the most sensitive imaging for OLT with a sensitivity of 96%. [] This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. J Bone Joint Surg Am. HHS They highlighted the heterogeneity of the data and suggested the need for high-quality prospective randomized studies using validated outcome measures for clarity regarding the effective modalities of treatment for OLT.[50]. Prognostic factors determining success of microfracture. They also proposed the radiological classification that is widely employed even to the present day. Patient age for all such options is a significant restrictive factor since transplanted cells and marrow cells tend to lose regenerative potential … This is an US FDA approved allograft technique and was first made available in 2007 by DeNovo NT, Natural Tissue Graft (Zimmer, Inc., Warsaw. studied the factors influencing the results of ACI in OLT and concluded that size >137 mm2 and age <26 years to be significantly associated with better MOCART (modified magnetic resonance observation of cartilage repair tissue) scores while patients sex, depth of the lesion, and presence or absence of accompanied procedure did not affect the results of ACI in OLT. in their study of 22 patients with successful initial non-operative treatment of OLT reported only minimal symptoms, a low failure rate, and no significant progression of ankle arthritis at a minimum follow-up of 10 years, though a substantial number of patients (>1/3rd) reported a decrease in sporting activity. Foot Ankle Int. This may cause complications of the donor site and the ankle. Furthermore, juvenile cartilage has been shown to possess copious cellular activity that results in formation of abundant extracellular matrix than its adult counterpart. This site needs JavaScript to work properly. The diagnosis of cartilage damage (osteochondral lesion, also known as talar dome) is often done with x-rays and/or an MRI. The key cost driver is the cost of the graft, but over the lifetime horizon, there are QALYs gained from using OCA, and there are cost savings later due to fewer people needing a TKA in the OCA arm. [6] In case of clinically suspected lesion with negative radiographs, advanced imaging options such as CT and MRI are useful. At this point the doctors in Portugal suggest surgery to fraguemento extraction and treatment of osteochondral lesion of about 12mm in size with the … This tissue is mechanically inferior, but the results of the procedure in the short term are generally good with smaller lesion (<1.5 cm 2) [16, 22]. Clinicians should have a high index of suspicion as symptoms and clinical signs may be non-specific. [29] Return to sports rate after microfracture is reported to be 76%, though most patients may not be able to achieve the pre-injury level. 2013 Apr;6(2):141-4. doi: 10.1177/1938640013479934. [6] Kouvalchouk et al. The etiology of osteochondral lesions of the talus is frequently attributed to ankle trauma but these lesions can also stem from alcohol abuse, chronic steroid use, endocrine abnormalities or genetics. Further sufficiently powered, randomized clinical trials with uniform methodology and validated outcome measures should be initiated to compare the outcome of surgical strategies for OCD of the talus. [47] A recent systematic review on the role of PJCAT in OLT involving 10 studies and 132 patients showed good postoperative functional outcomes, however, the regenerated cartilage was heterogeneous in nature with relatively unaltered subchondral area which is in contrast to the belief that PJCAT would restore the area of defect to near normal cartilage. Therapeutic arthroscopy with microfracture leads to fibrocartilaginous repair and is an effective treatment of osteochondral lesions of the talus. There is also the possibility to associate the treatment with growth factors. 2006;88:303–308. Foot Ankle Clin. My question is: For a young man with 13, with the condition that the correct option and including microfracture. -. 2003 Jun;8(2):233-42, viii-ix. Allograft juvenile articular cartilage transplantation for treatment of talus osteochondral defects. OATS, BMS and ACI scored success rates of 87, 85 and 76%, respectively. Although it still remains a 2-staged procedure, using a collagen matrix reduces the operative time and also helps in even distribution of chondrocytes. Most of the talus is covered by cartilage. Importance Osteochondral autologous transplantation surgery (OATS) is one of many treatment modalities for osteochondral lesions of the talus (OLT). These authors evaluate the effectiveness of procedures such as microfracture and arthroscopy, and recent innovations such as … Du cartilage articulaire du genou sont fréquentes lesion, with the condition that the correct option including.
