Limited by the amount of donor tissue that can be harvested, Osteochondral tissue harvested from fresh allograft talus and transplanted into the defect. Copyright © 2020 Lineage Medical, Inc. All rights reserved. The injury occurring on the medial aspect of the Talus is often deeper and cup shaped. If a lesion is seen on plain radiographs, Best method for accurately characterizing the size and extent of a defect, Tends to overestimate the size of a lesion because of bone marrow edema. All Rights Reserved. The most common sites are the posteromedial (53%) (, Most classification systems are based on lesion descriptions by Berndt and Harty (, Stage 2: Partially detached osteochondral fragment, Stage 3: Detached but stable/nondisplaced osteochondral fragment, Stage 5: Subchondral cyst (added by Loomer et al.) However, for the last six months, he has developed persistent ankle pain with intermittent swelling. 6,51 This cartilage is cultured to grow chondrocytes, which can be viable for longer than 1 year. Osteochondritis dissecans (OCD or OD) is a joint disorder primarily of the subchondral bone in which cracks form in the articular cartilage and the underlying subchondral bone. The differential diagnosis includes any cause of chronic pain in the region of the ankle joint: Occult fracture (5th metatarsal, lateral process of talus, medial or lateral malleolus). The bone lesions on the lateral or outside portion of the talus are most often related to trauma. When planning the treatment of osteochondral lesions of the talus, it is important to evaluate the articular cartilage to distinguish between stable and unstable lesions (1,2). Osteochondritis dissecans (OCD) of the talus is a disea-se affecting the subchondral bone and secondarily the articular cartilage. Stage 3 • Nondisplaced lesion with lucency: Stage 4 • Displaced fragment An osteochondral lesion of the talus (OLT) is an area of abnormal, damaged cartilage and bone on the top of the talus bone (the lower bone of the ankle joint). Defined as a separation of articular cartilage from the talar dome, with varying amounts of subchondral bone. Autologous chondrocyte transplantation in osteochondral lesions of the ankle joint. Procedures that reduce and stabilize the displaced fragment: Usually recommended only for lesions that are large enough to be amenable to internal fixation. Although Magnetic Resonance Imaging (MRI) at 1.5 Tesla is the leading cross-sectional modality for detection and staging of OCL, lack of … More complex scaffolds that better replicate the microarchitecture of articular cartilage may become available. Treatment algorithm for OLT lesions overlaps with the treatment for OCD and depends on lesion stability. focal injuries to the talar dome with variable involvement of the subchondral bone and cartilage resulting in osteochondral lesion of the talus (OLT), may be caused by traumatic event or result of repetitive microtrauma, ankle inversion and dorsiflexion during axial load creates shearing of lateral talar dome and lateral OLT, ankle inversion, external rotation, and plantarflexion during axial load creates shearing of medial talar dome and medial OLT, possible repeitive microtrauma creates ischemic environment and loss of integrity of subchondral bone, leads to softening and disruption of overlying cartilage, among the thickest in the body (implications for osteochondral autografting), maintains tensile strength longer than femoral head with aging process, deltoid artery supplies majority of talar body and dome. Doctors stage osteochondritis dissecans according to the size of the injury, whether the fragment is partially or completely detached, and whether the fragment stays in place. Perform general foot and ankle examination. 2F) (arrow). [] Although majority may be associated with trauma, some may develop insidiously. Overlying cartilage may degenerate . 3 A debridement of the chondral part is required if symptomatic. If the loosened piece of cartilage and bone stays in place, you may have few or no symptoms. Subchondral bone is penetrated to allow bleeding and fibrin clot formation. The historical term for this grouping of pathologies, osteochondritis dissecans (OCD), emphasized a localized vascular deficiency within the talus as the principle pathology with the symptoms being secondary to loss of adequate chondral support &/or cyst formation within the talus. Evaluate for tenderness over the talar dome. OCD of the talus usually occurs in patients aged between 10 and 40 years, and it peaks in the second decade of life. Santrock RD, Buchanan MM, Lee TH, et al. Loose bodies, fibrous tissue, and unstable cartilage are débrided. - Gregory Berlet, MD, Foot & Ankle⎪Osteochondral Lesions of the Talus, Asymptomatic Medial Talar Dome OCD in a 17M, Osteochondral Lesions of the Talus with Midfoot Arthritis, Talus fracture, OCD, cartilage fragment, subchondral cyst.

It can occur in all age groups. It is thought that mesenchymal stem cells in the clot lead to the formation of fibrocartilage. (OBQ13.46) The lateral injuries to the Talus (ankle bone) are usually shallow and cup shaped. This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. INTRODUCTION. An osteochondral lesion of the talus (OLT) is an area of abnormal, damaged cartilage and bone on the top of the talus bone (the lower bone of the ankle joint). Osteochondral defects of the talus is aseptic bone necrosis. For patients with CAI accompanied by talus … He complains of mechanical symptoms with ankle movement that continue to be symptomatic with everyday activities. There is an increasing prevalence of … unstable on probing; fragment not dislocated; complete discontinuity of the "dead in situ" lesion; stage IV 6,51 This cartilage is cultured to grow chondrocytes, which can be viable for longer than 1 year. x-ray findings: increased lucency between osteochondral fragment and remainder of the bone, or loose body with donor site irregularity. The coronal plane of the MRI demonstrates anteromedial lesions of OLT, Hepple stage 1 and 2A in figure 2A, and 2B (arrow), respectively. Giannini S, Buda R, Grigolo B, et al. Overlying cartilage may degenerate . Best modality for finding associated soft-tissue abnormalities, No difference in the effectiveness of CT and MRI in diagnosing an OCD (. The sagittal MRI demonstrates non-displaced mid-medial lesion of OLT, Hepple stage 3, in figure 2E (arrow) and displaced mid-lateral lesion of the OLT, Hepple stage 4, in (Fig. Stage VI: massive osteochondral defects of the talus. Cartilage damage was noted in 17–66% of ankles with lateral ligament injuries [ 3 , 12 , 21 , 26 ]. 1. Osteochondritis dissecans (OCD) is an aseptic bone necrosis and represents pathology of high clinical relevance, which is frequently located on the talus. On the lateral aspect of the ankle it most often occurs from trauma. ACI is a 2-stage procedure in which hyaline cartilage is harvested from the anterior aspect of the talus or a nonweightbearing portion of the knee in the first stage. Die genauen Ursachen, die zu dieser Erkrankung führen, sind noch nicht vollends verstanden, allerdings scheinen sich wiederholende Traumen oder Überbelastung sowie Durchblutungsstörungen am Knochen eine Rolle zu spielen. Raikin SM. OCDs of the talus represent damage to the articular surface of the talar dome in the ankle joint. Eighteen symptomatic advanced-stage osteochondritis dissecans (OCD) of the talus (Berndt and Harty stages III 7 and IV 11) in 17 patients were treated with multiple autogenous osteochondral cylindrical grafts. Stage 2 - partially attached osteochondral fragment / flap . Osteochondritis Dissecans (OCD) Talus/Tibia The ankle joint is composed of the bottom of the tibia (shin) bone and the top of the talus (ankle) bone. Physical examination elicits pain with ankle dorsiflexion and plantarflexion, although subtalar motion is normal. • Cystic lesion within dome of talus with an intact roof on all view, • Cystic lesion communication to talar dome surface. Most cases of osteochondritis dissecans of the talus occur around the time of skeletal maturity (10-14 years of age for girls and 12-16 years of age for boys). What would be the next most appropriate step for treatment? Tested Concept, Total contact cast immobilization and nonweight-bearing for 6 weeks, (OBQ12.74) ACI is a 2-stage procedure in which hyaline cartilage is harvested from the anterior aspect of the talus or a nonweightbearing portion of the knee in the first stage. Treatment is thus most appropriately based on the patient's symptoms, a very relevant fact given that many osteochondral lesions are incidental findings. ROM usually is started 2–6 weeks after surgery, depending on the quality of the osteotomy fixation. This condition is also known as osteochondritis dissecans (OCD) of the talus or a talar osteochondral lesion (OCL). Although OCD of the talus is, by definition, detachment of an osteochondral fragment of the talar dome occurring in a growing patient, symptomatic OCD is more typically observed in adults. Osteochondral lesions of the talus and the role of ankle arthroscopy. Although biomechanically inferior to hyaline cartilage, fibrocartilage formation appears to be sufficient for smaller lesions. Start as acute intra-articular fracture . Bony fragment may - revascularise & unite - undergo AVN & not unite . Examine for ankle instability (anterior drawer test, talar tilt test) or evidence of general ligamentous laxity. MRI is less useful for determining healing of OCD lesions because clinical healing may not correlate with imaging [ 5,20 ], and, in patients with operative repair, bony edema from instrumentation interferes with identification of healing during the postoperative period [ 44 ]. Osteochondritis dissecans (OCD) is the most common cause of a loose body in the joint space in adolescents1 and may lead to considerable debility. Radiography cannot directly depict the cartilage surface (3). Accept A 43-year-old male sustained a left ankle injury 3 years ago. Delaying surgical intervention for chronic OCD does not appear to alter results of later surgery. The authors of this study have since published the clinical outcome of one case with good improvement in functional scores and return to sports after one year. During his workup, an MRI shows a 1x1 cm lateral talar osteochondral defect (OCD). These lesions can be chronic in nature, as seen in Osteochondritis Dissecans (OCD). [] This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. • Complete fragment detachment but not displaced. Stage 1 - subchondral compression fracture . The talus is the 3rd most common site (after the knee and elbow) of osteochondral lesions. Infektionen des Knochens hingegen spielen keine Rolle in der Entstehung der Osteochondrosi… Maire-Clare Killen and Rajiv Limaye shed light on a path of treatment that is constantly evolving. Metal artifact can make MRI difficult to interpret in certain cases. (, No clear method is available for preventing this, Most patients who develop OCDs are in their 2nd–4th decades, with a mean age of 26.9 years (. In patients with OCD lesions of the dome of the talus, MRI is useful for preoperative evaluation. Read More, Copyright ©2007 Lippincott Williams & Wilkins, > Table of Contents > Osteochondral Defect of the Talus. Physical exam reveals some joint swelling but no ligamentous instability. This guide will help you understand 1. how OCD develops 2. how the condition causes problems 3. what can be done for your pain Treatment principles of osteochondral lesions of the ta… Weightbearing radiographs should be obtained initially. Acute fractures do better than chronic lesions. Osteochondral lesions of the talus. The top of the talus is dome-shaped and is completely covered with cartilage (connective tissue that allows the ankle to move smoothly). Osteochondral lesions of the talus. The axial MRI demonstrates mid-medial lesions of … The mean time of follow-up was 36 months (range, 25-49). The average age at surgery was 22.7 years (range, 19-34). Radiographs are unremarkable. The mean time of follow-up was 36 months (range, 25-49). Pathology . The most common cause of a talar lesion is due to an ankle sprain and up to 50 percent of sprains involve some injury to the cartilage. 1 ) and anterolateral (46%) talar dome ( 1 ).
