Die Osteochondrosis dissecans (OCD, auch angloamerikanisch Osteochondritis dissecans) ist die umschriebene aseptische Knochennekrose unterhalb des Gelenkknorpels, die mit der Abstoßung des betroffenen Knochenareals mit dem darüberliegenden Knorpel als freier Gelenkkörper enden kann. However, in early stages, the cartilage layer is intact, and the lesions may not be seen at arthroscopy. OCD of the talus usually occurs in patients aged between 10 and 40 years, and it peaks in the second decade of life. Ankle ROM exercises, peroneal strengthening, progressive ambulation, and proprioception training. Procedures that regrow hyaline cartilage, such as autologous chondrocyte transfer: Cartilage is harvested (usually from the knee) and grown in culture. Once enough cells are available, the chondrocytes are reimplanted into the defect. A 43-year-old male sustained a left ankle injury 3 years ago. - can have family history of talus OCD . The top of the talus is part of the joint and is covered with articular cartilage , … • There are… More complex scaffolds that better replicate the microarchitecture of articular cartilage may become available.

Stage 3 • Nondisplaced lesion with lucency: Stage 4 • Displaced fragment Physical examination elicits pain with ankle dorsiflexion and plantarflexion, although subtalar motion is normal. 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). Osteochondral lesion (OCL) is a term used to describe an injury or abnormality of the articular … [] Although majority may be associated with trauma, some may develop insidiously. When osteochondritis dissecans affects the ankle it typically occurs on the inner or medial portion of the ankle (talus). OCDs of the talus represent damage to the articular surface of the talar dome in the ankle joint. Treatment principles of osteochondral lesions of the ta… 3rd-generation techniques rely on a 3D bioscaffold to contain the cells instead of a periosteal flap (, Short-term clinical results generally are. A 21-year-old male reports right ankle pain after sustaining an inversion ankle injury 2 years ago. When not displaced, a chronic osteochondral fragment often is attached to the defect by fibrous tissue. x-ray findings: increased lucency between osteochondral fragment and remainder of the bone, or loose body with donor site irregularity. Evaluate for tenderness over the talar dome. The goal in osteochondral defects of the talus in Stages I and II according to Berndt and Harty is revascularization of the lesion. Physical exam reveals some joint swelling but no ligamentous instability. Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. Q: How are unstable OCD lesions of the ankle treated? Make sure the patient does not have other. Pathology . Berndt & Harty Xray Classification . Although biomechanically inferior to hyaline cartilage, fibrocartilage formation appears to be sufficient for smaller lesions. When compared to medial talar OCDs, which of the following statements is true regarding lateral talar OCDs? Fig. 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. The axial MRI demonstrates mid-medial lesions of … Giannini S, Vannini F. Operative treatment of osteochondral lesions of the talar dome: current concepts review. The lateral injuries to the Talus (ankle bone) are usually shallow and cup shaped. Stage 1 • Cystic lesion within dome of talus with an intact roof on all view: Stage 2a • Cystic lesion communication to talar dome surface: Stage 2b • Open articular surface lesion with the overlying nondisplaced fragment. He complains of mechanical symptoms with ankle movement that continue to be symptomatic with everyday activities. KEY FACTS • The natural history of osteochondral lesions of the talus appears to be fairly benign, especially as it relates to the risk of the development of arthritis. Weak evidence suggests that a genetic component might be involved in some OCDs (, OCDs can be produced in cadaveric models by shear and compression forces (, Chronic: Recurrent injury from chronic ankle instability, Lateral OCD is associated with a recognized traumatic episode in 93% of cases (, Medial OCD is associated with a recognized traumatic episode in 61% of cases (. Osteochondral defects of the talus is aseptic bone necrosis. Figures A and B are radiographs of the left ankle.

The most common sites are the posteromedial (53%) ( Fig. It can occur in all age groups. Osteochondral lesions of the talus. Arthroscopy provides the best and most direct method for evaluating the articular surface and treating the abnormality. The mosaicplasty technique for osteochondral lesions of the talus. 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. In patients with OCD lesions of the dome of the talus, MRI is useful for preoperative evaluation. OCDs of the talus represent damage to the articular surface of the talar dome in the ankle joint. Osteochondral injury staging system for MRI attempts to grade the stability and severity of osteochondral injury and is used to plan management. Osteochondral lesions of the talar dome can cause significant functional impairment and a decreased quality of life. Osteochondritis dissecans can be classified at surgery into 4 stages: stage I. stable; lesion in continuity with the host bone; covered by intact cartilage; stage II. 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). Overlying cartilage may degenerate . It is uncertain whether these OLT or conventional OCD (best studied in the knee) represent differ-ent manifestations of a common pathologic process or sepa-rate pathologies. Cyst may develop under fragment . 1–3 Two common lesions are notable on the talus. Osteochondritis dissecans, unspecified ankle and joints of foot. Weightbearing radiographs should be obtained initially. 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. © 2020 - TeachMe Orthopedics. These lesions are of high clinical relevance as they are commonly missed … Procedures that transfer hyaline cartilage to the defect: OATS/mosaicplasty, allograft transfer, Generally recommended for large lesions or lesions that fail other forms of treatment. - James Stone, MD, Evolving Technique: The Role Of Osteotomy For The Treatment Of Osteochondral Lesions Of The Talar Dome - Listen Up!- Phinit Phisitkul, MD, MACI & Newer Techniques: I Told You This Before: Wake Up Everyone! the talus” (OLT) [10]. Defined as a separation of articular cartilage from the talar dome, with varying amounts of subchondral bone. Infektionen des Knochens hingegen spielen keine Rolle in der Entstehung der Osteochondrosi… Start as acute intra-articular fracture . 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). The options for treating OCL are numerous and a number of surgical procedures can be performed arthroscopically. Procedures that reduce and stabilize the displaced fragment: Usually recommended only for lesions that are large enough to be amenable to internal fixation. The area where OCD occurs is located at the top of the talus. Santrock RD, Buchanan MM, Lee TH, et al. stable on probing; partial discontinuity of the lesion from the host bone; stage III. Although Magnetic Resonance Imaging (MRI) at 1.5 Tesla is the leading cross-sectional modality for detection and staging of OCL, lack of … Delaying surgical intervention for chronic OCD does not appear to alter results of later surgery. 6,51 This cartilage is cultured to grow chondrocytes, which can be viable for longer than 1 year. Radiographs at the time were negative and his pain improved over the next two months. Physical therapy and NSAID's have not alleviated the symptoms. Depending on how the ankle is injured, the problem can occur on the side of the talus closest to the other foot or on the outside part. Treatment algorithm for OLT lesions overlaps with the treatment for OCD and depends on lesion stability. Die Osteochondrosis dissecans (kurz OCD bzw. Osteochondral lesions (OCL) of the talus involve both articular cartilage and subchondral bone of the talar dome. Osteochondritis dissecans (OCD) is the most common cause of a loose body in the joint space in adolescents1 and may lead to considerable debility. 1) and anterolateral (46%) talar dome (1).

Dr. Ebraheim’s educational animated video describes Osteochondral Lesions of the Talus. Autologous chondrocyte transplantation in osteochondral lesions of the ankle joint. Any procedure that requires an osteotomy necessitates nonweightbearing until the osteotomy heals (4–8 weeks). It often develops above a bone cyst. All Rights Reserved. Brostrum), medial malleolar osteotomy for medial and posterior lesions, longitudinal incision centered over medial malleolus, flexor retinaculum released posteriorly; PTT retracted posteriorly, osteotomy guided based of 2 parallelly placed K-wires, with goal to enter plafond at lateral extent of OLT, prior to osteotomy, 2 drill holes placed to aid in reduction following procedure, sagittal saw and osteotome used to complete osteotomy, care taken not to cause thermal necrosis to bone or damage cartilage, lateral malleolar osteotomy or ATFL/CFL release for lateral lesions, longitudinal incision centered over lateral malleolus, oblique osteotomy planned, with predrilling of small fragment screws holes to aid in reduction following procedure, alternatively, if lateral ligament reconstruction is planned, extensor retinaculum may be released, peroneal tendons retracted posteriorly and ATFL and CFL released, ankle inverted and plantarflexed to expose talar dome, OLT debrided and measured using sizing guide, appropriately sized autograft may be harvested from knee and placed into OLT, impacted gently into defect, OATs harvested from the knee have a cartilage thickness less than the native talus, this will cause immediate post-operative xrays to show a prominent graft despite the cartilage surface being flush, do not release deltoid ligament as may jeopardize deltoid artery blood supply, ankle impingement if graft plug left proud, small percentage of patients do not achieve pain relief regardless of treatment, Posterior Tibial Tendon Insufficiency (PTTI), lesions may progress to involve entire ankle joint, mechanical symptoms such as catching or locking, arthroscopic harvest of chondrocytes (from ankle or alternatively from knee) are sent for cultured growth, open approach via osteotomy for implantation, debridement of lesion to create stable cartilage rim, subchondral bone exposed, bone graft may be placed if underlying cyst and bone loss, periosteum from tibia taken and fitted to defect, this is sutured into place this small caliber suture, omitting one area to leave access to underlying defect, water-tight seal confirmed, cultured chondrocytes placed under flap and suture placed, fibrin glue placed over defect, newer technique of matrix-based chondrocyte implantation (MACI) shown equivalent outcomes to ACI and may obviate need for osteotomy. Although the cartilage cap remains viable (. - 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. 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. Loose bodies, fibrous tissue, and unstable cartilage are débrided. 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. • Cartilage injury with underlying fracture and surrounding bony edema, • Stage 2a without surrounding bone edema, often limited secondary to pain or effusion, evaluate for ligamentous laxity or insufficiency, suspicion for OLT in setting of equivocal radiographs, helpful in evaluating subchondral bone and cysts, less reliable in purely cartilaginous lesions of nondisplaced OLTs, provides fine detail of lesions for pre-operative planning, persistent pain following injury, ankle sprains that do not heal with time, variable edema patterns, may overestimate degree of injury, unstable lesions show fluid deep to subchondral bone, predicts stability of lesion with 92% sensitivity, nondisplaced fragment with incomplete fracture, size > 1 cm and displaced lesions, shoulder lesions, salvage for failed marrow stimulation or drilling, period of immobilization in cast or boot for 6 weeks, followed by progressive weight bearing with physical therapy emphasizing peroneal strengthening, range of motion, and proprioceptive training, Arthroscopy with marrow stimulation (microfracture or antegrade drilling), debridement of unstable cartilage flaps to create stable and contained defect using curettes or shaver, loose bodies and cartilage removed using shaver or grasper, microfracture awl placed perpendicular to surface and tapped into subchondral bone 2-4 mm deep, inflow stopped to allow fat or blood to emanate from holes, indicating adequate penetration, Kirschner wire can be passed using anterior portals, or transmalleolar for central or posterior lesions, talus dorsiflexed and plantar flex to necessitate only 1 transosseous passing of wire, articular cartilage delamination and graft failure, 65-90% improvement in patient reported outcomes, fibrocartilage formation at site of lesion in 60% of patients on second-look arthroscopy, no correlation noted with patient outcomes, Arthroscopy with retrograde drilling and bone grafting, evaluate cartilaginous surface for softening, dimpling with probe seen, Kirschner wire drilled from sinus tarsi into defect, fluoroscopy often helpful to confirm location, if bone grafting indicated, cannulated drill placed over K wire, Osteochondral autograft and allograft transplant, dictated by location of OLT and concomitant procedures required (i.e. Osteochondritis dissecans (OCD) is an aseptic bone necrosis and represents pathology of high clinical relevance, which is frequently located on the talus. Osteochondritis dissecans (OCD) of the talus is a disea-se affecting the subchondral bone and secondarily the articular cartilage. 2F) (arrow). Berndt AL, Harty M. Transchondral fractures (osteochondritis dissecans) of the talus. INTRODUCTION. 1 ) and anterolateral (46%) talar dome ( 1 ). 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. Loomer R, Fisher C, Lloyd-Smith R, et al. It is thought that mesenchymal stem cells in the clot lead to the formation of fibrocartilage. Therefore, ankle fracture, sprain, and chronic ankle instability are risk factors. If the subchondral bone is not violated, no healing occurs. There is an increasing prevalence of … Stage 2 - partially attached osteochondral fragment / flap . Sie kann die meisten Gelenke des menschlichen Körpers betreffen, sie tritt aber vor besonders häufig im oberen Sprunggelenk … (OBQ13.46) If the loosened piece of cartilage and bone stays in place, you may have few or no symptoms. Cyst may develop under fragment . 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.) ankle is a highly congruent mortise joint, oriented 15 degrees externally from midsagittal line of ankle, talus articulates with the medial malleolus medially, tibial plafond superiorly, posterior malleolus posteriorly, and fibula laterally. With proper treatment, the prognosis generally is good.

OD, angloamerikanisch auch Osteochondritis dissecans) ist eine umschriebene Knochenläsion unterhalb des Gelenkknorpels, die mit der Abstoßung des betroffenen Knochenareals mit dem darüberliegenden Knorpel als freier Gelenkkörper (Gelenkmaus) enden kann. The diagnosis of OCD most frequently depends on obtaining an imaging study: Plain radiographs or CT, MRI, or bone scans. This guide will help you understand 1. how OCD develops 2. how the condition causes problems 3. what can be done for your pain The talus is the 3rd most common site (after the knee and elbow) of osteochondral lesions. • Complete fragment detachment but not displaced. Accept The average age at surgery was 22.7 years (range, 19-34). Stage 1 - subchondral compression fracture . It is also called an osteochondral defect (OCD) or talar osteochondral lesion (OCL). Other possible causes include ischemic events (AVN). If the subchondral bone is violated, the defect attempts to heal with fibrous tissue or fibrocartilage. 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. • Open articular surface lesion with the overlying nondisplaced fragment. The talus is the 3rd most common site (after the knee and elbow) of osteochondral lesions. The top of the talus is dome-shaped and is completely covered with cartilage (connective tissue that allows the ankle to move smoothly). Osteotomy usually is required as part of the surgical approach. 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. Maire-Clare Killen and Rajiv Limaye shed light on a path of treatment that is constantly evolving. 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). For patients with CAI accompanied by talus … “Osteo” means bone and “chondral” refers to cartilage. Examine for ankle instability (anterior drawer test, talar tilt test) or evidence of general ligamentous laxity. Most classification systems are based on lesion descriptions by Berndt and Harty ( 2 ): Osteochondral lesions of the talus are commonly associated with a traumatic injury to the ankle joint. 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. (, 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 (. The talus is the 3rd most common site (after the knee and elbow) of osteochondral lesions. This condition is also known as osteochondritis dissecans (OCD) of the talus or a talar osteochondral lesion (OCL). Bony fragment may - revascularise & unite - undergo AVN & not unite . We'll assume you're ok with this, but you can opt-out if you wish. The bone lesions on the lateral or outside portion of the talus are most often related to trauma. MRI staging system for osteochondral lesion of the talus. 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. Perform general foot and ankle examination. 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. However, for the last six months, he has developed persistent ankle pain with intermittent swelling. Radiographs are unremarkable. Coronal T1-weighted image of the ankle, showing a medial talar OATS. Treatment is thus most appropriately based on the patient's symptoms, a very relevant fact given that many osteochondral lesions are incidental findings. On the lateral aspect of the ankle it most often occurs from trauma. Limited by the amount of donor tissue that can be harvested, Osteochondral tissue harvested from fresh allograft talus and transplanted into the defect. The mean size of defect of OCD was 13.6 mm × 7.2 mm. Pathology . 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 . Cannot evaluate subchondral abnormalities. Complications include malunion or nonunion of an osteotomy, persistent pain, stiffness, and arthritis. 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. This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. 1, 24 This debridement is limited to loose The average age at surgery was 22.7 years (range, 19-34). The incidence of osteochondral defects (OCD) of the talus is 0.09 % in the literature with a prevalence of 0.002 per 100,0001-3. Tested Concept, Increased incidence of traumatic etiology, (OBQ06.213) In later stages of the disorder there will be swelling of the affected joint which catches and locks during movement. Osteochondritis dissecans (OCD) of the talus is a subchondral bone pathology that presents as an osteochondral lesion of the talar dome with consequent articular cartilage abnormalities. 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. The most common sites are the posteromedial (53%) (Fig. Bei der Osteochondrosis dissecans stirbt ein Teil des Knochens unterhalb des Gelenkknorpels ab, sodass sich dieser ablösen kann und in der Gelenkhöhle lose vorliegt (Dissektat). 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). Talar hemiarthroplasty Using a metallic prosthesis for OCL of the talus was first described in 2010 for a defect of the medial talar dome in a cadaver [37]. The ankle is the third most frequently affected site, after the knee and elbow, and it accounts for 4% of all OCD cases (1, 2). What is the next appropriate step in the management of this patient? Both magnetic resonance (MR) imaging and ankle arthroscopy are excellent tools commonly used to evaluate ankle cartilage (3–5). Microfracture or drilling: 4–6 weeks of nonweightbearing is recommended to allow the defect to heal, with ankle ROM encouraged. Osteochondral lesions of the talus. Nonoperative management recommendations range from activity modification alone to nonweightbearing in a cast. Acute fractures do better than chronic lesions. Copyright © 2020 Lineage Medical, Inc. All rights reserved. Stable Most cases of OCD usually follow a twisting injury to the ankle and are actually fractures of the joint surface. A 30-year-old professional ballet dancer presents with persistant ankle pain after an ankle sprain 6 months ago. Radiography cannot directly depict the cartilage surface (3). The injury occurring on the medial aspect of the Talus is often deeper and cup shaped. Figure C shows the corresponding MRI. Raikin SM. Es verbleibt dann ein Gelenkflächendefekt (Mausbett). Metal artifact can make MRI difficult to interpret in certain cases. 3 A debridement of the chondral part is required if symptomatic. 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 ]. Growth factors and the use of mesenchymal stem cells also will be important in refining the procedure and improving results. Osteochondral defect (OCD) or lesion of the talus can accompany chronic lateral ankle instability (CAI). Die OCD kann die meisten Gelenke des men… • Cystic lesion within dome of talus with an intact roof on all view, • Cystic lesion communication to talar dome surface. Cartilage damage was noted in 17–66% of ankles with lateral ligament injuries [ 3 , 12 , 21 , 26 ]. Osteochondral lesions of the talus and the role of ankle arthroscopy. Bony fragment may - revascularise & unite - undergo AVN & not unite . What would be the next most appropriate step for treatment? The mean time of follow-up was 36 months (range, 25-49). This term refers to a wide spectrum of pathologies including mild bone marrow contusion as well as severe osteoarthritis resulting from long standing disease. Overlying cartilage may degenerate . Free, official coding info for 2021 ICD-10-CM M93.279 - includes detailed rules, notes, synonyms, ICD-9-CM conversion, index and annotation crosswalks, DRG grouping and more. These lesions can be chronic in nature, as seen in Osteochondritis Dissecans (OCD). 1. The MRI demonstrates the osteochondral lesions of the talus (OLT). Subchondral bone is penetrated to allow bleeding and fibrin clot formation. Examine for crepitus or mechanical signs with ankle ROM. [] This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. 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.
