-, Becher C, Thermann H. Results of microfracture in the treatment of articular cartilage defects of the talus. Arthroscopic treatment of the OLTs aims to restore ankle joint function and pain relief by the removal of the chondral or osteochondral fragment, debridement and stabilization of cartilage rim and subchondral bone, and stimulate healing of the bone and damaged cartilage. [Diagnosis and treatment of osteochondral lesions of the talus]. doi: 10.1016/s1083-7515(02)00064-5. Anders et al. You may need to keep weight off the foot and use crutches during this period of immobilization. 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. 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. 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. Care must be … Verhagen RA, Struijs PA, Bossuyt PM, van Dijk CN. Stable, well-aligned fractures, however, can often be treated without surgery. 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. 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. [2] Lee et al. [2,39] Flynn et al. eCollection 2020 Jul. Please enable it to take advantage of the complete set of features! Plain radiography is the initial investigation of choice in a clinically suspected case of OLT. 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? 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. Thus, treatment should be individualized to every patient, with adequate counseling regarding the outcomes and associated complications of that technique. [14] Provocative tests such as anterior drawer test should be performed and compared to the unaffected side to evaluate the associated instability. [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. Osteochondritis dissecans(OCD) is a problem that causes pain and stiffness of the ankle joint. Secondary cyst formation and subchondral … Chahla 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. [24], Operative treatment is indicated for OLT that have remained symptomatic even after a conservative trial for 3–6 months. Rationale of conservative treatment is to offload the affected area for resolution of bone marrow edema and to facilitate healing of the detached cartilage. Growth factors contained in PRP can facilitate cartilage repair by stimulating matrix formation and increasing chondrocyte proliferation. [28], The prognostic factors that determine the success of microfracture are listed in [Table 3]. Although outcomes of most of these techniques are promising, it is hard to recommend one procedure over another due to lack of comparative analyses. 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. [23] A level-II randomized study conducted by Mei-Dan et al. NLM Fifty-two studies described the results of 65 treatment groups of treatment strategies for OCD of the talus. A history of ankle trauma/recurrent instability is to be elicited as OLT are associated with ankle instability. Operative techniques can be broadly classified as cartilage repair, regeneration, and replacement techniques [Table 2]. [46] This harvested cartilage is then transferred to the area of defect and secured using fibrin glue. J Bone Joint Surg Am. acute injury; nondisplaced fragment with incomplete fracture; Operative. BMJ Open. Autologous osteochondral grafting for talar cartilage defects. These repetitive injuries may result in microtrauma in an already vulnerable bone with sparse vascularity causing OLT. 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). Most often, there are no symptoms of talus OCD. Clipboard, Search History, and several other advanced features are temporarily unavailable. Osteochondral lesions of the talus (OLTs) are a difficult pathologic entity to treat. Then applying the surgical technique which will be most successful achieving the goal. C. Icing is important for the first 5-7 days post-op. that included four studies concluded that PRP used in conjunction with microfracture results in better pain and functional improvement than microfracture alone. doi: 10.1136/bcr-2020-234595. 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. In more than one third of cases, conservative treatment is unsuccessful, and surgery is indicated. [26] Furthermore, the quantity and quality of fibrocartilage formed may vary. Orthopade. © Copyright 2020 – Journal of Arthroscopic Surgery and Sports Medicine – All rights reserved.Published by Scientific Scholar on behalf of Indian Arthroscopy Society. 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. Patient’s consent not required as patients identity is not disclosed or compromised. There is probably a small chance of healing with the current plan of bone stimulator and restricted weight bearing. 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. -. [1] Klammer et al.  |  The size of the lesion is the main factor to consider. Causes: Microtrauma-seen in runner or old age. There are several non-operative management options for the treatment of osteochondral lesions, including: Cast immobilization: If the OLT occurs following an acute injury, initial immobilization in a cast for 4-6 weeks can help reduce stress on the OLT and allow healing. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. OLT encompass a wide variety of disorders that are both difficult to diagnose and also to treat with varying functional outcomes. [5] The sole indication for operative treatment at presentation is an acute lesion with displacement.

Foot Ankle Int. Finite Element Analysis of the Effect of Talar Osteochondral Defects of Different Depths on Ankle Joint Stability. Operative treatment of osteochondral lesions of the talus. [28] Despite these findings, microfracture still seems to be resulting in good functional outcomes. Varied etiology and non-specific clinical signs make the diagnosis of these lesions challenging. Foot Ankle Clin. [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). They reported favorable outcomes with 86% of patients having no pain or only mild pain, no advancement of MRI staging in 84% of patients, and no significant ankle arthritis at final follow-up, though many patients reported minor discomfort on activities of daily living and sporting activities. 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.

Treatment depends on the severity of the talar dome lesion. in 1986. 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. You will likely have a cast and need to use crutches for a few weeks to allow the bone injury to heal. There are numerous reasons that make the talar cartilage and the subchondral bone prone to vascular insufficiency. Arthroscopy. doi: 10.12659/MSM.921823. These eventually would form fibrocartilage at the defect. Ice is applied for 20-minute periods 3-4 times per day. [2] This technique is effective in treating large cystic lesions even up to 6 cm2 with favorable outcomes reported. Treatment depends on the severity of the talar dome lesion. If there are symptoms, they may include: Pain that gets worse with activity and improves with rest. [53], In summary, outcomes following surgery are variable and thus treatment strategy has to be tailored to every patient depending on specific factors. This guide will help you understand 1. how OCD develops 2. how the condition causes problems 3. what can be done for your pain 2006;88:303–308. [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]. They require a strong plan. [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. [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. and Hepple et al. NIH [46] As cartilage tissue is immune deprived, it is also not associated with immune reactions. Most cases of OCD usually follow a twisting injury to the ankle and are actually fractures of the joint surface. Rationale of conservative treatment is to offload the affected area for resolution of bone marrow edema and to facilitate healing of the detached cartilage. [1] This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. Malays Orthop J. You may need to keep weight off the foot and use crutches during this period of immobilization. Pain medication as needed every 6 hours. [13] All these factors make the talus prone for developing osteochondral lesions. [49], This is a second-generation technique that employs a collagen matrix instead of a periosteal sleeve to secure the chondrocytes. Diagnosis. 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. [42,43] These grafts can then be employed for bulk transfer after size matching using CT scan. Foot Ankle Spec. [50] Kreulen et al. An MRI is often done to assess the nature of the OCD and the risk for it to come loose. [2] Although majority may be associated with trauma, some may develop insidiously. 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. [25] Useful algorithm describing the indication for each procedure is outlined in [Figure 1]. chronic lesions ; size < 1 cm MRI is the most sensitive imaging for OLT with a sensitivity of 96%. Together with the newer techniques OATS and ACI, BMS was identified as an effective treatment strategy for OCD of the talus. It is designed for rehabilitation following surgical repair of OCD of Talus. RESULTS: A total of 104 patients with chronic ankle instability were included in this study. Guney et al. There are only a few … Autologous chondrocyte transplantation for treating cartilage defects of the talus. In more severe cases however, ankle surgery may be indicated. HA is known to reduce inflammation in the joint while simultaneously substituting joint fluid. [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. [19] Commonly used classifications are summarized in [Table 1]. In view of these limitations, surgical treatments for OCD of the talus present an overall success rate of 79%. Furthermore, improvement was better when PRP was used as an adjunct to microfracture than a conservative intraarticular injection of PRP. The proportion of the patient population treated successfully was noted, and percentages were calculated. [22], Injection therapy alone with PRP or HA has also been attempted in the treatment of OLT. 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. For each treatment strategy, study size weighted success rates were calculated. -, Alexander AH, Lichtman DM. Limited, Coimbatore, Tamil Nadu, Department of Orthopedics and Spine surgery. If the lesion is stable (without loose pieces of cartilage or bone), one or more of the following nonsurgical treatment options may be considered: Immobilization: Depending on the type of injury, the leg may be placed in a cast or cast boot to protect the talus. One randomized clinical trial was identified. However, due to great diversity in the articles and variability in treatment results, no definitive conclusions can be drawn. This is usually done with a combination of immobilization and then rehabilitation. Fifty-two studies described the results of 65 treatment groups of treatment strategies for OCD of the talus. Vascularization is severely restricted when fragments are displaced, in which case surgery may be the only way to heal the lesion. In general talus OCD is difficult to get healed with or without surgery. [5] In 1959, Berndt and Harty were the first to describe the pathogenesis of osteochondral lesions post-trauma. Left untreated this can lead to degenerative changes to the ankle joint and evan necrosis of the talus. Clinicians should have a high index of suspicion as symptoms and clinical signs may be non-specific. 1999;15:197–202. J Bone Joint Surg Am. 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 … Lesion size, location, chronicity, and characteristics such as displacement and the presence of subchondral cysts help dictate the appropriate treatment required to achieve a … Bai L, Guan S, Liu S, You T, Xie X, Chen P, Zhang W. Orthop J Sports Med. Donor site morbidity and the need for a medial malleolus osteotomy remain its major disadvantages.

Osteochondral transplantation of autologous graft for the treatment of osteochondral lesions of talus: 5- to 7-year follow-up. We use cookies to ensure that we give you the best experience on our website. Annals of Clinical and Analytical Medicine. described the classifications of OLT based on CT and MRI, respectively. HHS Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. J Bone Joint Surg Am. During this period of immobilization, non-weightbearing range-of-motion exercises … indications . Osteochondral lesions of the talus encompass important clinical conditions encountered in day-to-day practice. This is an US FDA approved allograft technique and was first made available in 2007 by DeNovo NT, Natural Tissue Graft (Zimmer, Inc., Warsaw. Osteochondral Lesions of the Talus Indications & Outcomes • Comparison of 39 studies treating ankle OCD’s with excision, excision and curettage, osteochondral transplantation, fixation, retrograde drilling) –(level 2) •Best outcome (86% good to excellent results) with: [6] Kouvalchouk et al. Ferkel’s grading is the most commonly employed grading system on arthroscopy. [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. A cast will hold the bones in your foot in place while they heal. 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. 2020 Jul;14(2):64-71. doi: 10.5704/MOJ.2007.014. [16] Ferkel et al. This initial evaluation often leads to a broad differential diagnosis including ankle synovitis, impingement, occult fractures, and early ankle/subtalar arthritis.[2]. 2016 Dec;24(12):3722-3729. doi: 10.1007/s00167-014-3389-3. 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. [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). [44] A systematic review by Richard et al. A systematic review of 52 studies including 1236 primary OLT by Dahmen et al. There are only a few recent studies that have reported the outcomes following non-operative management. Availability of fresh donor allografts and the associated cost is also a concern in developing countries. [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. Surgical options for the treatment of osteochondral lesions of the talus are numerous and have expanded over the past few years. 2003 Jun;8(2):233-42, viii-ix. 2020 Jul 28;8(7):2325967120937798. doi: 10.1177/2325967120937798. If you continue to use this site we will assume that you are happy with it. It can occur in all age groups. Nonsurgical Treatment. Surgical technique should be mainly chosen depending on the status of the overlying cartilage, size, and containment of the lesion. 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. Knee Surg Sports Traumatol Arthrosc. [30], Polat et al. [54] to detect the most effective treatment for OLT concluded that none of the interventions were clinically superior over another. 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. [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.

Prognostic factors determining success of microfracture. Electronic databases from January 1966 to December 2006 were systematically screened.  |  [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. arthroscopy with removal of the loose fragment, debridement and marrow stimulation . Allograft juvenile articular cartilage transplantation for treatment of talus osteochondral defects. Introduction. Annals of Clinical and Analytical Medicine; inquiry In children whose bones are still growing, the bone defect may heal with a period of rest and protection. [52] A systematic review of level 1 and 2 studies by Yausep et al. [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. 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. [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. Although it still remains a 2-staged procedure, using a collagen matrix reduces the operative time and also helps in even distribution of chondrocytes. Immobilization – Depending on the type of injury, the leg may be placed in a cast or cast boot to protect the talus. Talus osteochondral defects (OCD) are considered as a common cause of chronic ankle pain and disability. Occasional swelling. B. Treatment Options for OCD Ankle Lesions If OLT is diagnoses immediately after the injury, immobilization of the foot and ankle for a period of time usually resolves the problem. Treatment for OCD depends on when the problem is discovered. BMJ Case Rep. 2020 Jul 8;13(7):e234595. Al-Shaikh RA, Chou LB, Mann JA, et al. This site needs JavaScript to work properly. Retrograde drilling and fixation scored 88 and 89%, respectively. Occasional joint locking. 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. 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%. 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. Either way if you have such a fracture treatment will require non weight bearing cast for 4-6weeks and X-ray exams during that period for evaluation of bone healing. indications . [10], Most OLT are secondary to trauma, with up to 50% of ankle sprains resulting in some grade of cartilage injury. One randomized clinical trial was identified. Answers from doctors on ocd of talus. 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. 2002;23:381–389. 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. [27] Toale et al. Both non-operative and operative modalities have been described for the treatment of OLT. Surgical treatment is indicated after a failed conservative trial, larger lesion and can be broadly split into cartilage repair, replacement, and regenerative strategies. Trauma-seen with ankle fractures and sprains. 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. [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]. No single treatment works for everybody. This finding seems to confirm the paramount importance of early surgical treatment for OCD. This option is useful for large OLT with extensive subchondral cysts. immobilization and non-weight bearing. USA.gov. Casting. Epub 2014 Oct 19. doi: 10.2106/JBJS.E.00033.
