[Diagnosis and treatment of osteochondral lesions of the talus]. [50] Kreulen et al. [27] Toale et al. Left untreated this can lead to degenerative changes to the ankle joint and evan necrosis of the talus. 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. Clinicians should have a high index of suspicion as symptoms and clinical signs may be non-specific. HHS indications . Furthermore, PRP group had significantly better outcomes than the HA group. 2020 Jul;14(2):64-71. doi: 10.5704/MOJ.2007.014. 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. eCollection 2020 Jul. HA is known to reduce inflammation in the joint while simultaneously substituting joint fluid. [26] Furthermore, the quantity and quality of fibrocartilage formed may vary. [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. This option is useful for large OLT with extensive subchondral cysts. Orthopade. One randomized clinical trial was identified. Osteochondral lesions of the talus (OLTs) are a difficult pathologic entity to treat. Autologous osteochondral grafting for talar cartilage defects. If the problem is discovered immediately after a twisting injury to the ankle, immobilization in a cast or boot for six weeks may be suggested to see if the bone injury heals. [16] Ferkel et al. [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. BMJ Case Rep. 2020 Jul 8;13(7):e234595. 2003 Jun;8(2):233-42, viii-ix. There is a wide variety of treatment strategies for osteochondral defects of the ankle, with new techniques that have substantially increased over the last decade. 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. J Bone Joint Surg Am. 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. An MRI scan was performed at follow-up to assess talus OCD after treatment. Occasional swelling. Outcomes following surgery are variable and thus treatment strategy has to be tailored to every patient based on specific factors. [28], The prognostic factors that determine the success of microfracture are listed in [Table 3]. Ankle Arthroscopy + Microfracture Talus OCD (Osteochondritis Dissecans lesion) Day of Surgery A. This finding seems to confirm the paramount importance of early surgical treatment for OCD. This procedure is a single-stage procedure and as it does not require a press fit or graft contouring due to its particulate nature, it can be carried out arthroscopically. 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. Varied etiology and non-specific clinical signs make the diagnosis of these lesions challenging. [2] Decision-making depends mainly on the stability of the overlying cartilage, size, and the containment of the lesion (shoulder and non-shoulder type lesion). [44] A systematic review by Richard et al. described the classifications of OLT based on CT and MRI, respectively. Surgery to treat an open talus fracture often involves much more than lining up the broken pieces of bone. [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. It is designed for rehabilitation following surgical repair of OCD of Talus. In view of these limitations, surgical treatments for OCD of the talus present an overall success rate of 79%. 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. and Hepple et al. [1] This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. During this period of immobilization, non-weightbearing range-of-motion exercises … Trauma-seen with ankle fractures and sprains. reported a reoperation rate of 25% with development of moderate or severe ankle arthritic changes, pain due to hardware-related complications, graft collapse, and non-union/delayed union at osteotomy site as reasons for reoperation with a failure rate of 13.2%. [2] This technique is effective in treating large cystic lesions even up to 6 cm2 with favorable outcomes reported. [5] In 1959, Berndt and Harty were the first to describe the pathogenesis of osteochondral lesions post-trauma. Lesions with large cystic areas, diffuse arthritic changes, ankle malalignment, and prior history of infections are contraindications to this procedure. Berndt and Harty classification is the staging system that is widely employed for describing OLT on plain radiographs. [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. in 1986. [52] A systematic review of level 1 and 2 studies by Yausep et al. MRI is the most sensitive imaging for OLT with a sensitivity of 96%. [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. You may need to keep weight off the foot and use crutches during this period of immobilization. Treatment of coexisting OLT and ligamentous instability Acute ankle ligament injuries with a large, unstable fragment typically first undergo surgical repair of the talar lesion. USA.gov. Then applying the surgical technique which will be most successful achieving the goal. They require a strong plan. © Copyright 2020 – Journal of Arthroscopic Surgery and Sports Medicine – All rights reserved.Published by Scientific Scholar on behalf of Indian Arthroscopy Society. [37] Morphological evaluation post-retrograde drilling using second look arthroscopy showed no worsening of overlying cartilage at 1-year follow-up.  |  This site needs JavaScript to work properly. Ice is applied for 20-minute periods 3-4 times per day. Donor site morbidity and the need for a medial malleolus osteotomy remain its major disadvantages. [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]. ISSN (Print): AwaitedISSN (Online): 2582-7332, © 2020 Published by Scientific Scholar on behalf of Journal of Arthroscopic Surgery and Sports Medicine, Department of Arthroscopy & Foot and Ankle, Ganga Medical Centre and Hospital Pvt. The size of the lesion is the main factor to consider. COVID-19 is an emerging, rapidly evolving situation. [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. This initial evaluation often leads to a broad differential diagnosis including ankle synovitis, impingement, occult fractures, and early ankle/subtalar arthritis.[2]. Autologous chondrocyte transplantation for treating cartilage defects of the talus. Diagnosis. Introduction. Without appropriate treatment, talus OCD have the potential to lead early cartilage degeneration and eventually osteoarthritis. Foot Ankle Spec. Annals of Clinical and Analytical Medicine. Annals of Clinical and Analytical Medicine; inquiry Knee Surg Sports Traumatol Arthrosc. Although the treatment of osteochondral lesions of the talus has evolved and improved, there is a need to understand the full spectrum of treatments and be well-versed in all forms of treatment in order to have a complete bag of tools necessary to treat these complicated occurrences. -, Baums MH, Heidrich G, Schultz W, et al. Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. [5] The sole indication for operative treatment at presentation is an acute lesion with displacement. Epub 2014 Oct 19. treatment of OCD of the talus Ji viable cartilage, the fragment is not displaced, then the rate of healing is very high and surgery is not required. Foot Ankle Int. A history of ankle trauma/recurrent instability is to be elicited as OLT are associated with ankle instability. 1. [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). Treatment of osteochondritis dissecans is intended to restore the normal functioning of the affected joint and relieve pain, as well as reduce the risk of osteoarthritis. [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 aim of this study was to summarize all eligible studies to compare the effectiveness of treatment strategies for osteochondral defects (OCD) of the talus. I wish you and your … Although it still remains a 2-staged procedure, using a collagen matrix reduces the operative time and also helps in even distribution of chondrocytes. B. described the natural history of OLT in 43 patients who opted for conservative treatment with a minimum follow-up of 2 years. Many talus fractures require surgery because of the high-energy force that creates the injury. There are only a few recent studies that have reported the outcomes following non-operative management. No single treatment works for everybody. [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. Med Sci Monit. -, Becher C, Thermann H. Results of microfracture in the treatment of articular cartilage defects of the talus. This guide will help you understand 1. how OCD develops 2. how the condition causes problems 3. what can be done for your pain [53], In summary, outcomes following surgery are variable and thus treatment strategy has to be tailored to every patient depending on specific factors. Ankle and navicular are two seperate areas. For each treatment strategy, study size weighted success rates were calculated. If there are symptoms, they may include: Pain that gets worse with activity and improves with rest. Together with the newer techniques OATS and ACI, BMS was identified as an effective treatment strategy for OCD of the talus. [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. 1980;62:646–652. 2013 Jun 5;95(11):1045-54. doi: 10.2106/JBJS.L.00773. Plain radiography is the initial investigation of choice in a clinically suspected case of OLT. Research studies show OCD lesion in the talus in 70% of ankle fractures, 60% of ankle sprains. Care must be … National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. 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. Pain medication as needed every 6 hours. J Bone Joint Surg Am. Patient’s consent not required as patients identity is not disclosed or compromised. Surgical options for the treatment of osteochondral lesions of the talus are numerous and have expanded over the past few years. 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). Although outcomes of most of these techniques are promising, it is hard to recommend one procedure over another due to lack of comparative analyses. 2020 Aug 21;26:e921823. [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]. Occasional joint locking. 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). Please enable it to take advantage of the complete set of features! Ferkel’s grading is the most commonly employed grading system on arthroscopy. These eventually would form fibrocartilage at the defect. [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. Conservative Treatment of Talar Osteochondritis Dissecans (OCD) Ezequiel Palmanovich1 and Meir Nyska1 (1) Foot and Ankle Unit – Orthopedic Department, Meir Medical Center – Israel, kfar Saba, Israel Ezequiel Palmanovich Email: ezepalm@gmail.com 2.1 Introduction Since 1922 when this syndrome was first described by Kappis [1],… We use cookies to ensure that we give you the best experience on our website. In children whose bones are still growing, the bone defect may heal with a period of rest and protection. doi: 10.12659/MSM.921823. Fifty-two studies described the results of 65 treatment groups of treatment strategies for OCD of the talus. indications . [2,39] Flynn et al. [54] to detect the most effective treatment for OLT concluded that none of the interventions were clinically superior over another. 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. During this period of immobilization, nonweightbearing range-of-motion exercises may be recommended. Treatment depends on the severity of the talar dome lesion. -, Alexander AH, Lichtman DM. Guney et al. 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. Patients present with spectrum of non-specific complaints including of pain on weight-bearing, swelling, stiffness, and occasionally locking sensation at the ankle joint. 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. [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. Retrograde drilling and fixation scored 88 and 89%, respectively. [46] As cartilage tissue is immune deprived, it is also not associated with immune reactions. Surgical treatment includes arthroscopic drilling of intact lesions, securing of cartilage flap lesions with pins or screws, drilling and replacement of cartilage plugs, stem cell transplantation, and in very difficult situation in adults joint replacement. Growth factors contained in PRP can facilitate cartilage repair by stimulating matrix formation and increasing chondrocyte proliferation. This treatment approach can be initially attempted in non-displaced OLTs Knee Surg Sports Traumatol Arthrosc. Arthroscopic treatment of transchondral talar dome fractures: a long-term follow-up study. 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. doi: 10.1016/s1083-7515(02)00064-5. 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. In more than one third of cases, conservative treatment is unsuccessful, and surgery is indicated. [4] In 1922, Kappis extrapolated the concept of spontaneous necrosis at the hip to the etiopathogenesis of foreign bodies in the ankle joint and used the term osteochondritis dissecans. Casting. 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. Immobilization – Depending on the type of injury, the leg may be placed in a cast or cast boot to protect the talus. C. Icing is important for the first 5-7 days post-op. Osteochondral lesions of the talus encompass important clinical conditions encountered in day-to-day practice. [49], This is a second-generation technique that employs a collagen matrix instead of a periosteal sleeve to secure the chondrocytes. Most cases of OCD usually follow a twisting injury to the ankle and are actually fractures of the joint surface. Surgery is often needed to better assess the lesion and determine the goal of either lesion healing or removal. Fibrocartilage is predominantly made of Type I collagen which is structurally and biomechanically inferior to hyaline cartilage. There are numerous reasons that make the talar cartilage and the subchondral bone prone to vascular insufficiency. [25] Useful algorithm describing the indication for each procedure is outlined in [Figure 1]. Foot Ankle Clin. Availability of fresh donor allografts and the associated cost is also a concern in developing countries. Treatment options for large talar osteochondral lesions (greater than 1.5 cm) or those that fail to adequately respond to microfracture, have broadened over the last decade, with most procedures directly aimed at hyaline-like cartilage restoration. 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. Treatment for OCD depends on when the problem is discovered. You may need to keep weight off the foot and use crutches during this period of immobilization. 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. Operative treatment of osteochondral lesions of the talus. Electronic databases from January 1966 to December 2006 were systematically screened. [42,43] These grafts can then be employed for bulk transfer after size matching using CT scan. [10], Most OLT are secondary to trauma, with up to 50% of ankle sprains resulting in some grade of cartilage injury. 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. 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 … [22], Injection therapy alone with PRP or HA has also been attempted in the treatment of OLT. [24], Operative treatment is indicated for OLT that have remained symptomatic even after a conservative trial for 3–6 months. [1] Klammer et al. There are only a few … Allograft juvenile articular cartilage transplantation for treatment of talus osteochondral defects. 2005;26:583–589. [46] This harvested cartilage is then transferred to the area of defect and secured using fibrin glue. Thus, treatment should be individualized to every patient, with adequate counseling regarding the outcomes and associated complications of that technique. 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]. 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. Choi et al. that included four studies concluded that PRP used in conjunction with microfracture results in better pain and functional improvement than microfracture alone. To date, there are no randomized controlled trials on the efficacy of osteochondral lesion treatments and most publications that exist are of low quality with short-term follow-up and varying conclusions. This is usually done with a combination of immobilization and then rehabilitation. [2] The rationale is to form a hyaline cartilage at the defect from pluripotent cells instead of fibrocartilage that forms after microfracture alone. Foot Ankle Int. Fifty-two studies described the results of 65 treatment groups of treatment strategies for OCD of the talus. Treatment for OCD depends on when the problem is discovered. 2013 Apr;6(2):141-4. doi: 10.1177/1938640013479934. 2006;88:303–308. -, Baker CL, Jr, Morales RW. [13] All these factors make the talus prone for developing osteochondral lesions. Diet as tolerated. 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. doi: 10.1136/bcr-2020-234595. Rationale of conservative treatment is to offload the affected area for resolution of bone marrow edema and to facilitate healing of the detached cartilage. A systematic review of 52 studies including 1236 primary OLT by Dahmen et al. Surgical technique should be mainly chosen depending on the status of the overlying cartilage, size, and containment of the lesion. [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. Although OCD of the talus represents a frequently observed orthopedic pathology, evidence concerning operative treatment of osteochondrosis dissecans of the talus is still elusive. Causes: Microtrauma-seen in runner or old age. 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.
