IN) to treat patellar lesion. [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). Systematic review of treatment strategies for osteochondral defects of the talar dome. MRI is the most sensitive imaging for OLT with a sensitivity of 96%. 2003 Jun;8(2):233-42, viii-ix. Recovery and surgery for an OCD lesion of the knee. [Diagnosis and treatment of osteochondral lesions of the talus]. Radiographs showed a suspicious area on the lateral talar dome. Retrograde drilling and fixation scored 88 and 89%, respectively. INTRODUCTION. Operative techniques can be broadly classified as cartilage repair, regeneration, and replacement techniques [Table 2]. Patient age for all such options is a significant restrictive factor since transplanted cells and marrow cells tend to lose regenerative potential … [5] In 1959, Berndt and Harty were the first to describe the pathogenesis of osteochondral lesions post-trauma. -, Baums MH, Heidrich G, Schultz W, et al. The purpose of this study is to evaluate the outcomes of lesions treated with osteochondral allograft transplantation. 2013 Apr;6(2):141-4. doi: 10.1177/1938640013479934. 1999;15:197–202. Commonly, multiple cylinders have to … 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. 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… Most of the talus is covered by cartilage. There was a significantly lower cost for return to play in athletes after OAT versus microfracture at 1 year ($11,428 vs $16,953, respectively), 3 years ($12,856 vs $38,000, respectively), and 10 years ($32,141 vs $60,799, respectively). However, if we cannot get insurance approval for this material due to cost (about $7,000), we will use the aforementioned BioCartilage product instead. [6] In case of clinically suspected lesion with negative radiographs, advanced imaging options such as CT and MRI are useful. [2] This technique is effective in treating large cystic lesions even up to 6 cm2 with favorable outcomes reported. These eventually would form fibrocartilage at the defect. 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]. [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. Furthermore, it is hard to figure out why some osteochondral lesions, small or large, are painful and some are not painful. A treatment gap exists for patients with lesions not suitable for arthroplasty or biologic repair or who have failed prior cartilage repair surgery. If you continue to use this site we will assume that you are happy with it. doi: 10.1016/s1083-7515(02)00064-5. The first description of osteocartilaginous loose bodies in the ankle, attributed to trauma, was given by Monro in 1738. Actual surgical treatments for osteochondral lesions and early knee osteoarthritis seem to be promising. Osteochondral allograft transplantation has been performed for the past 50 or more years with several studies demonstrating satisfactory outcomes. Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. Bai L, Guan S, Liu S, You T, Xie X, Chen P, Zhang W. Orthop J Sports Med. 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. J ISAKOS. 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. Clipboard, Search History, and several other advanced features are temporarily unavailable. of the talus but at the cost of a hi gh rate of. 2005;26:583–589. 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. The tibia and fibula bones sit above and to the sides of the talus, forming the ankle joint. 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/. The cost-per-point change in functional outcome score was $200.59 for MFx, $313.84 for OAT, and $536.59 for ACI-1. 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. Introduction. [53], In summary, outcomes following surgery are variable and thus treatment strategy has to be tailored to every patient depending on specific factors. FIGURE 71-1 Osteochondral lesion of the talus. Foot Ankle Spec. Malays Orthop J. Long-term follow-up. The aim of this study was to summarize all eligible studies to compare the effectiveness of treatment strategies for osteochondral defects (OCD) of the talus. [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. 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. Osteochondral lesions of the talus encompass important clinical conditions encountered in day-to-day practice. [26] Furthermore, the quantity and quality of fibrocartilage formed may vary. Finally, the treatment of such lesions is comprehensive … Once the piece has broken off, surgery is almost always necessary. Osteochondral lesions of the talus (OLTs) continue to be a challenge for the treating surgeon, especially when lesions are refractory to marrow stimulation techniques. Al-Shaikh RA, Chou LB, Mann JA, et al. INTRODUCTION. Foot Ankle Clin. USA.gov. The mosaicplasty technique for osteochondral lesions of the talus. Fifteen patients underwent mosaic osteochondral transplantation to treat a talar osteochondral defect lesion, with 11 patients available for follow-up. OATS, BMS and ACI scored success rates of 87, 85 and 76%, respectively. In both studies magnetic resonance imaging (MRI) was performed prior to open reduction and internal fixation (ORIF). Foot Ankle Int. Allograft juvenile articular cartilage transplantation for treatment of talus osteochondral defects. 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. Patient’s consent not required as patients identity is not disclosed or compromised. 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 ). 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? 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. Med Sci Monit. [22], Injection therapy alone with PRP or HA has also been attempted in the treatment of OLT. Furthermore, juvenile cartilage has been shown to possess copious cellular activity that results in formation of abundant extracellular matrix than its adult counterpart. 2008 Mar;37(3):204, 206-11. doi: 10.1007/s00132-008-1219-3. Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. Orthopade. 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. Yang and Lee revealed incomplete healing and inferior quality of cartilage in 36% (9/25) ankles in a second look arthroscopy analysis of arthroscopic microfracture at a mean follow-up of 3.6 years. Electronic databases from January 1966 to December 2006 were systematically screened. Therapeutic arthroscopy with microfracture leads to fibrocartilaginous repair and is an effective treatment of osteochondral lesions of the talus. 6-8 These treatment methods … 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. [24], Operative treatment is indicated for OLT that have remained symptomatic even after a conservative trial for 3–6 months. OLT encompass a wide variety of disorders that are both difficult to diagnose and also to treat with varying functional outcomes. … Outcome. 2020 Jul 28;8(7):2325967120937798. doi: 10.1177/2325967120937798. Methods: The study included 28 patients (17 males, 11 females; mean age 30.3 years; range 22-55 years) who had osteochondral lesions of the talus and were treated by arthroscopic surgery. Patients present with spectrum of non-specific complaints including of pain on weight-bearing, swelling, stiffness, and occasionally locking sensation at the ankle joint. Chahla et al. However, due to great diversity in the articles and variability in treatment results, no definitive conclusions can be drawn. This is an US FDA approved allograft technique and was first made available in 2007 by DeNovo NT, Natural Tissue Graft (Zimmer, Inc., Warsaw. The procedure has a low morbidity and complication rate and low cost and is technically undemanding. Donor site morbidity and the need for a medial malleolus osteotomy remain its major disadvantages. Anders et al. [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. These authors evaluate the effectiveness of procedures such as microfracture and arthroscopy, and recent innovations such as … Both non-operative and operative modalities have been described for the treatment of OLT. [38], This technique involves harvesting osteochondral plugs from donor sites such as non-weight-bearing portions of the knee and implantation of these plugs to the areas of osteochondral defects. 2016 Dec;24(12):3722-3729. doi: 10.1007/s00167-014-3389-3. Arthroscopic treatment of transchondral talar dome fractures: a long-term follow-up study. Because MRI may overdiagnose or overestimate the extent of OCLs in an acute trauma setting the aim of this study was … © Copyright 2020 – Journal of Arthroscopic Surgery and Sports Medicine – All rights reserved.Published by Scientific Scholar on behalf of Indian Arthroscopy Society. An OCD lesion of the ankle is a specific type of injury to the bottom bone in the ankle joint. Although it still remains a 2-staged procedure, using a collagen matrix reduces the operative time and also helps in even distribution of chondrocytes. 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]. 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. -. They are most commonly associated with ankle trauma and wh… 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]. [] Although majority may be associated with trauma, some may develop insidiously. The mean lesion size for microfracture was 3.4 cm 2, which is larger than the indicated size for this procedure. Osteochondral Allograft transplantation for knee lesions after failure of cartilage repair surgery. -, Becher C, Thermann H. Results of microfracture in the treatment of articular cartilage defects of the talus. An osteochondral cyst can also be present following surgery. [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. The talus is the bottom bone of the ankle joint. 1,2 Researchers have reported an occurrence of up to an astounding 73 percent in ankle fracture cases … 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. [49], This is a second-generation technique that employs a collagen matrix instead of a periosteal sleeve to secure the chondrocytes. 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. Also read: Should you play sports with an OCD lesion in your knee? [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]. Growth factors contained in PRP can facilitate cartilage repair by stimulating matrix formation and increasing chondrocyte proliferation. Although outcomes of most of these techniques are promising, it is hard to recommend one procedure over another due to lack of comparative analyses. Operative treatment of osteochondral lesions of the talus. The diagnosis of cartilage damage (osteochondral lesion, also known as talar dome) is often done with x-rays and/or an MRI. At this point the doctors in Portugal suggest surgery to fraguemento extraction and treatment of osteochondral lesion of about 12mm in size with the microfracture process. 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. Arthroscopic surgery is sometimes referred to as “keyhole surgery” as it is performed through very small incisions. | 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. In both studies magnetic resonance imaging (MRI) was performed prior to open reduction and internal fixation (ORIF). Knee Surg Sports Traumatol Arthrosc. A non-shoulder-type lesion is defined as a chondral defect that has surrounding articular cartilage (a contained cartilage defect), whereas a shoulder-type lesion does not have a peripheral cartilage border on one side with the loss of the medial or lateral articular buttress (uncontained defect). After a longer follow-up, some patients showed that the beneficial results were not maintained, indicating the deterioration of the … J Bone Joint Surg Am. Furthermore, improvement was better when PRP was used as an adjunct to microfracture than a conservative intraarticular injection of PRP. There is also the possibility to associate the treatment with growth factors. A systematic review of 52 studies including 1236 primary OLT by Dahmen et al. Arthroscopic microfracture is the most frequently performed procedure for an osteochondral lesion of the talus (OLT) [1,2,3,4]. 2016. Prognostic factors determining success of microfracture. Fifty-two studies described the results of 65 treatment groups of treatment strategies for OCD of the talus. In this video, I discuss the types of surgery and how you might recover from those surgeries. [10], Most OLT are secondary to trauma, with up to 50% of ankle sprains resulting in some grade of cartilage injury. High-impact activities, such as running and jumping, should be avoided until 6 to 12 months after surgery. BMJ Case Rep. 2020 Jul 8;13(7):e234595. [2] Although majority may be associated with trauma, some may develop insidiously. [52] A systematic review of level 1 and 2 studies by Yausep et al. eCollection 2020 Jul. [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]. Osteochondral defects of the talus (OCD) are a well-established pathology within the ankle. | Background: The incidence of osteochondral lesions (OCLs) in association with displaced ankle fractures has only been examined in two previous studies. of the talus but at the cost of a hi gh rate of. Limited, Coimbatore, Tamil Nadu, Department of Orthopedics and Spine surgery. [] This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. [1] Klammer et al. [37] Morphological evaluation post-retrograde drilling using second look arthroscopy showed no worsening of overlying cartilage at 1-year follow-up. 2020 Jul;14(2):64-71. doi: 10.5704/MOJ.2007.014. described the classifications of OLT based on CT and MRI, respectively. 30 In addition, the publication used to obtain the costs associated with MFx, OAT, and ACI-1 only accounts for the costs up to 1 year postsurgery, so any required revisions after this period are unaccounted for. The knee and the ankle joint are the most commonly involved joints for OCLs in the lower extremity. Choi et al. [28] Despite these findings, microfracture still seems to be resulting in good functional outcomes. doi: 10.12659/MSM.921823. They also proposed the radiological classification that is widely employed even to the present day. Clinicians should have a high index of suspicion as symptoms and clinical signs may be non-specific. Verhagen RA, Struijs PA, Bossuyt PM, van Dijk CN. 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. -, Alexander AH, Lichtman DM. BMJ Open. J Bone Joint Surg Am. Finite Element Analysis of the Effect of Talar Osteochondral Defects of Different Depths on Ankle Joint Stability. 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). in their study of 165 consecutive ankles with OLT demonstrated good functional outcomes and improved quality of life in patients at 6.7 years of follow-up. [46] This harvested cartilage is then transferred to the area of defect and secured using fibrin glue. 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. Much of this bone is covered with cartilage. Background: The incidence of osteochondral lesions (OCLs) in association with displaced ankle fractures has only been examined in two previous studies. First, the talar cartilage is relatively thinner with a thickness of 0.7–1.2 mm compared to that of other joints of the lower extremity. This may cause complications of the donor site and the ankle. COVID-19 is an emerging, rapidly evolving situation. 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. Osteochondral transplantation of autologous graft for the treatment of osteochondral lesions of talus: 5- to 7-year follow-up. [50] Kreulen et al. 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. In 90 percent of patients, grafts survive at least 10 years. Importance Osteochondral autologous transplantation surgery (OATS) is one of many treatment modalities for osteochondral lesions of the talus (OLT). Autologous osteochondral grafting for talar cartilage defects. Surgical treatment options for the management of focal chondral and osteochondral lesions in the knee include biological solutions and focal metal implants. [12] Second, arterial supply to the talar dome and the overlying cartilage is by a retrograde vascular network that comes from the talar neck with additional watershed areas showing poor perfusion in the posteromedial, posterolateral, and mid-medial segments of the subchondral bone. [25,32-36], In OLT with subchondral cysts and intact overlying cartilage, retrograde drilling is a better modality that penetrates the necrosed subchondral bone without disturbing the overlying cartilage. Guney et al. Because MRI may overdiagnose or overestimate the … [46] As cartilage tissue is immune deprived, it is also not associated with immune reactions. There is limited understanding of cartilage damage and its repair. [13] All these factors make the talus prone for developing osteochondral lesions. One randomized clinical trial was identified. Ferkel’s grading is the most commonly employed grading system on arthroscopy. 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. Rationale of conservative treatment is to offload the affected area for resolution of bone marrow edema and to facilitate healing of the detached cartilage. [21] Weigelt et al. [2] Lee et al. Please enable it to take advantage of the complete set of features! [5] The sole indication for operative treatment at presentation is an acute lesion with displacement. Surgical treatment of transchondral talar-dome fractures (osteochondritis dissecans). For each treatment strategy, study size weighted success rates were calculated. transplantation surgery fo r osteochondral lesions. Surgical treatment is indicated after a failed conservative trial, larger lesion and can be broadly split into cartilage repair, replacement, and regenerative strategies. Foot Ankle Int. Availability of fresh donor allografts and the associated cost is also a concern in developing countries. My question is: For a young man with 13, with the condition that the correct option and including microfracture. in their review of 82 patients reported increase in arthrosis by one grade radiologically though none of the patients had Grade IV arthritis at a minimum follow-up of 5 years. 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. 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. Plain radiography is the initial investigation of choice in a clinically suspected case of OLT. 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. Varied etiology and non-specific clinical signs make the diagnosis of these lesions challenging. This initial evaluation often leads to a broad differential diagnosis including ankle synovitis, impingement, occult fractures, and early ankle/subtalar arthritis.[2]. These repetitive injuries may result in microtrauma in an already vulnerable bone with sparse vascularity causing OLT. [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]. 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. Diagram shows the classic four signs of instability in an OCD lesion: 1, high signal intensity rim at the interface between the fragment and the adjacent bone on T2-weighted MR images; 2, fluid-filled cysts beneath the lesion; 3, a high-signal-intensity line extending through the articular cartilage overlying the lesion; and 4, a focal osteochondral defect filled with joint fluid. [23] A level-II randomized study conducted by Mei-Dan et al. 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. 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. Autologous chondrocyte transplantation for treating cartilage defects of the talus. [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. This joint permits much of the up (dorsiflexion) and down (plantarflexion) motion of the foot and ankle. [42,43] These grafts can then be employed for bulk transfer after size matching using CT scan. in 1986. 2013 Jun 5;95(11):1045-54. doi: 10.2106/JBJS.L.00773. | 2020 Aug 21;26:e921823. 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.

The skeleton … There are a number of treatment options. Arthroscopy. Osteochondral Lesion Anatomy. [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. [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]. [44] A systematic review by Richard et al. In some rare cases, osteochondral lesions can occur for no apparent reason. Treating osteochondral lesions of the talus can pose challenges and delayed diagnosis due to late presentation after an ankle sprain. [2] The rationale is to form a hyaline cartilage at the defect from pluripotent cells instead of fibrocartilage that forms after microfracture alone. OATS uses bone-cartilage cylinder grafts from a non-weight bearing portion of another joint and transplants these on the site of the defect. This consists of particles of live cartilage that enable the surgeon to truly lay down the best quality cartilage. NLM A full diagnostic arthroscopy is performed, and then attention is turned to the osteochondral defect. [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.
