Specific changes in the program will be made by the physician as appropriate for the individual patient. Am J Sports Med 37 (2009) 105- 111. A crack in the cartilage on the surface of the bone can occur. Platelet-rich plasma is significantly better than hyaluronic acid. At the end, OCL fragments can break off and dislocate all over the joint. Here’s a list of the 15 best ankle braces and supports for all kinds of injuries: Zamst A2-DX Ankle Brace. This protocol provides you with general guidelines for initial stage and progression of rehabilitation according to specified time frames, related tissue tolerance and directional preference of movement. Management may be non surgical or surgical with follow up physiotherapy treatment essential for a return to normal activities and/or to sport. An osteochondral lesion to the talar dome is an injury that causes damage to the cartilage that sits on top of the talus. [13] Reduced ROM usually persists for 4-6 weeks after the acute event and walking on uneven ground may aggravate symptoms. The ankle may demonstrate acute injury with swelling and ecchymosis or it may appear completely normal, as is often the case with delayed presentations. The different options for secondary repairs depend on whether the OCL is predominantly a problem of the chondral layer, the osseous part, or a combination of both, on the age of the patient and the size of the OCL (Tables 71-2 and 71-3). Treatment Options for OCD Ankle Lesions. An untreated OCL represents a local osteoarthritis model because of the altered joint biomechanics. The therapist would probably focus on the quadriceps (a thigh muscle) and especially on the vastus medial;is (part of the quadriceps). What Is the Best Treatment for Recurrent Ankle Instability? J Bone Joint Surg (Br) 2007; 89(6):772 -777. The defect is what’s called an osteochondral lesion, and it can cause pain and swelling in the joint and ultimately could develop into osteoarthritis. Further surgical treatment included the elimination of the OCL risk factor, chronic ankle instability, by lateral and medial ligament repair. Therapeutic arthroscopy with microfracture leads to fibrocartilaginous repair and is an effective treatment of osteochondral lesions of the talus. should be checked. Osteochondral autograft is used for smaller cartilage defects. What Is the Best Treatment for End-Stage Hallux Rigidus? osteochondral defects of the ankle ML Reilingh, MD CJA van Bergen, MD CN van Dijk, MD, PhD Department of Orthopaedic Surgery, Academic Medical Centre, University of Amsterdam, Amsterdam, The Netherlands Corresponding address: Academic Medical Centre University of Amsterdam Department of Orthopaedic Surgery Prof Dr C Niek van Dijk PO Box 22660 1100 DD Amsterdam, The Netherlands … Increased cyst formation compared to images of 2011, but diminished bone oedema. Strengthening and range-of-motion exercises can help once your injury has healed adequately and can reduce swelling and pain. Active Ankle Dorsiflexion (foot up) and Plantarflexion (foot down) Move foot up and down (1 repetition) Repeat 20 times over 60 seconds. The treatment of OCLs of the talus includes a primary (as fixation of a flake fracture in traumatic cases) or a secondary repair (surgical treatment of chronic OCLs). Osteochondral autograft transplantation is used to address small to medium defects (1–4 cm 2), often with associated bone loss. Read more, © Physiopedia 2020 | Physiopedia is a registered charity in the UK, no. The top of the talus is dome-shaped and is completely covered with cartilage—a tough, rubbery tissue that enables the ankle to move smoothly. As the injury is intra-articular an MRI is required to diagnose the extent of the injury. How is it caused? This condition is also known as osteochondritis dissecans (OCD) of the talus or a talar osteochondral lesion (OCL). If osteochondral lesions on the ankle are not diagnosed early the bone fragment is not likely to heal and can continue to cause problems. Clinically, OCL ankle joints show, in almost all cases, a swelling and effusion. References About 6 months after osteochondral reconstruction, the patient is pain free, has an excellent function, and is back to daily life (job, sports). The CT scan is therefore a valuable diagnostic for preoperative planning. [7], An osteochondral lesion is rarely diagnosed via a physical exam without further testing. Clinical outcome and magnetic resonance imaging after osteochondral autologous transplantation in osteochondritis dissecans Do Bone Morphogenetic Proteins Improve Spinal Fusion? In these cases, the most affected area is the posteromedial talar dome (see Table 71-1). OCLs are articular injuries of the subchondral bone and the overlaying cartilage. • von Knoch F et al. Hereby, a traumatic osteochondral defect (flake fracture) or pathologic chronic shear forces (CAI. Their clinical presentation is described and advice is given on how to diagnose and investigate suspected osteochondral injuries. Doctors give unbiased, helpful information on indications, contra-indications, benefits, and complications: Dr. Yousefpour on physical therapy for osteochondral defect knee: Physical therapy would involve a programs or range of motion, and strengthening. 2005 Jan-Mar; 40(1): 35–40.

VALDERRABANO, MD, PhD, ANDRÉ LEUMANN, MD. Lastly, diagnostic ankle arthroscopy remains a reliable diagnostic tool, allowing direct and dynamic examination of the talus OCLs and the ankle-stabilizing ligaments.14. An osteochondral ankle defect is a lesion of the talar cartilage and subchondral bone mostly caused by a single or multiple traumatic events, leading to partial or complete detachment of the fragment. Last, a commonly used arthroscopic classification is the OCL classification of the International Cartilage Repair Society.5, Epidemiologically, the ankle registers 4% of all the human osteochondral defects.6 The cause of OCLs of the talus has multiple facets. Osteochondral injuries occur more often than thought and result in significant disability and pain.

The talus is a bone in the foot that helps form the ankle joint. On the basis of repetitive microtraumas, avascular necrosis, genetics, endocrinic reasons, or systemic reasons, the nontraumatic causative agent with osteonecrosis represents to date still an unclear pathomechanism of chronic OCLs (longer than 2 months). 31, No. An osteochondral injury to the talar dome produces pain at the ankle and you will find walking and other weight bearing activities difficult. What Are the Best Diagnostic Criteria for Lateral Epicondylitis? A full diagnostic arthroscopy is performed, and then attention is turned to the osteochondral defect. Perform knee cartilage damage exercises. the talar dome) in the ankle. MRI: Medial osteochondral lesion of the talus, with central piece of bone. If a cartilage defect is too large for an autograft, an allograft may be considered. 22(7):544– 51, 2001. Osteochondral tissue harvested from fresh allograft talus and transplanted into the defect Best for large (>3 cm 2 ) lesions, as an alternative to arthrodesis ( 10 ) 66% success rate ( 11 ) Lesions can then be subdivided as stable or unstable and non-displaced or displaced. The talar dome has no direct muscle attachments(2); during norm… can best be initially accessed with our initial visualiza-tion and working portals. Osteochondral injury (or osteochondral defect) of the ankle is an injury to the bone or smooth cartilage covering the joint surface in the ankle. Foot Ankle Int. The knee and the ankle joint are the most commonly involved joints for OCLs in the lower extremity. Osteochondral defect is a broad term that describes the morphological change of a localized gap in the articular cartilage and subchondral bone 5.It is often used synonymously with osteochondral injury/defect and in the pediatric population. 71-1). This surgery may be performed open or arthroscopically. osteochondral defects of the talar dome. Valderrabano V, Leumann A, Rasch H, Egelhof T, intermann B, agenstert G Knee-to-ankle mosaicplasty for treatment of osteochondral lesions of the ankle joint. They may also be called osteochondritis dessicans or osteochondral fractures. It is often associated with a traumatic injury such as a severe ankle sprain. Osteochondral defects (OCDs) of the talus are a common cause of residual pain after ankle injuries. However, it can be subdivided into a traumatic and nontraumatic cause. Osteochondral lesion of the talus (OLT) is a term used to describe an injury or abnormality of the talar articular cartilage also known as osteochondral defect (OCD). These symptoms place the ability to walk, work and perform sports at risk. The Ferkel and Sgaglione3 classification is a CT-based classification describing fragmentation, osteonecrosis, and cyst formations (stage I-IV). Radiographs provide information on the OCL location and stage only if the x-rays hit the OCL perpendicular, that is, if the OCL lies on the highest point of the talar dome. Your ankle joint is made up of the top of the ankle (talus) bone and the bottom of the shin (tibia) bone. Osteochondral lesions may also involve the talar dome, most frequently the medial aspect. When two bones move relative to each other, their surface consists of a softer substance that we call cartilage. Currently, six characteristics are used to categorise a particular lesion. [6], Non-surgical: Osteochondral lesions of the ankle can be treated with injections of Platelet-rich plasma and hyaluronic acid, which results in a decrease in pain scores and an increase in function for at least 6 months. 23. To make these surfaces slide more easily, there is also fluid in the joint that is created by the capsule of the joint. Foot Ankle Int 21:119–126 PubMed Google Scholar. Impaired function, limited range of motion, stiffness, catching, locking and swelling may be present. It is often associated with a traumatic injury such as a severe ankle sprain. Osteochondral Defects in the articular cartilage can result from trauma, arthritic conditions, chronic wear and tear. Choi WJ, Youn HK, Choi GW, Park YJ, Lee JW, Osteochondral Lesions of the Talus; Are There Any Differences Between Osteochondral and Chondral Types? When refering to evidence in academic writing, you should always try to reference the primary (original) source. [2], A lesion can also be categorised by its location on the articular surface of the talus as medial, lateral, or central with added subdivisions into anterior, central, or posterior as advocated by some authors. Terminology. Along with their details, we also reviewed them to ensure that you’re aware of all the pros and cons before you make a buying decision. Physiotherapy treatment is vital for all patients with an osteochondral lesion of the talar dome to maximise the healing process, ensuring an optimal outcome and to reduce the likelihood of recurrence. How is it caused? The Berndt and Harty classification has the advantage of being popular, but it does not accurately reflect the integrity of the articular cartilage. Chapter 71 What Is the Best Treatment for Ankle Osteochondral Lesions? Osteochondral cylinders are harvested from lesser marginal weight-bearing areas of the knee joint and press-fitted into the prepared defect. MRI provides complementary information, for example, the status of the OCL overlaying cartilage, information on bony edema, and the situation of the ligaments. The various treatment options currently available are briefly reviewed. Overall, more than 80% of the talus OCLs are of traumatic origin.7,8 In such traumatic cases, the acute OCLs are frequently located on the lateral dome of the talus (anterolateral) (Table 71-1). 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. OCLs are articular injuries of the subchondral bone and the overlaying cartilage. Osteochondral defects (OCDs) are very localised areas of joint damage which can occur in a number of different joints , not just the ankle. Many of them lose their sports career or even jobs by disability. • Woelfle JV et al. Trauma plays the most important role in the pathomechanism of talus OCLs. Buy Membership for Orthopaedics Category to continue reading. 2013;37:1697-1706. It is also called an osteochondral defect (OCD) or talar osteochondral lesion (OCL). Radiographs (A, B) showed a suspicious area on the lateral talar dome. It can be done with an arthroscope. Hereby, the most common reasons are a severe inversion ankle sprain, chronic ankle instability (CAI; causing in 5–9% of the cases a lateral talar OCL),9,10 or a fracture mechanism. Most ankle sprains occur when the foot is pointed downwards, and the ankle “rolls over” the foot, causing the talus (ankle bone) to push into the tibia. Sign up to receive the latest Physiopedia news, The content on or accessible through Physiopedia is for informational purposes only. Here, one should be alert on not missing a radiologically correlating hindfoot malalignment (hindfoot varus or valgus) that could explain the overload on the painful OCL joint region. The ankle joint is composed of the bottom of the tibia bone (shin) and the top of the talus bone (ankle). An osteochondral ankle defect involves the articular cartilage and subchondral bone (usually of the talus) and is mostly caused by an ankle supination trauma. It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). [15] Stage 1,2 and 3 lesions are less likely to progress to arthritis and do well with non-operative management. Other diagnoses sharing similar symptoms: [8][9], The location of the lesion, lesion size, containment, number of lesions, and combined intra-articular lesions can be identified through a preoperative MRI and are finally determined by arthroscopic surgery. 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. This is because the healthy graft tissue can only be taken from a limited area of the same joint. The top of the talus is dome-shaped and is completely covered with cartilage. MRI is the gold standard for OCL diagnosis, providing information about bone bruise, cartilage status and soft tissues. Ankle sprain is the most common medical history noted by patients. Osteochondral lesion of the talus. The defects cause deep ankle pain associated with weightbearing. Success rates for nonoperative treatment with sports restriction and nonsteroidal anti-inflammatory drug or cast immobilization differ from 0% to 100% (review article12). Success rates for nonoperative treatment with sports restriction and nonsteroidal anti-inflammatory drug or cast immobilization differ from 0% to 100% (review article, In most of the conservatively treated OCL cases, the pain remains untreated and the disease advances to further stages. Other tests should be performed to measure the range of motion for stiffness and to feel for the crepitus and signs of clicking or locking. With this excessive invertion force, the talus is rotated laterally within the mortis joint in the frontal plane, impacting and compressing the lateral talar margin against the articular surface of the fibula. VICTOR. Commonly, multiple cylinders have to be transplanted to fill larger defects. Scintigraphy showed to be useful in evaluating OCLs when radiographs appear to be normal.4,13 Addressing the lack of anatomic accuracy of the classic scintigraphy, a new diagnostic tool for OCLs emerged: the SPECT-CT. This is a main cause of ankle morbidity. The treatment of OCLs of the talus includes a primary (as fixation of a flake fracture in traumatic cases) or a secondary repair (surgical treatment of chronic OCLs). In the image, the ankle on the right indicates bone oedema. Epidemiologically, the ankle registers 4% of all the human osteochondral defects. 2016:1-12. Symptomatic osteochondral ankle defects often require surgical treatment. Osteochondral ankle defects(OCD): Symptoms & Treatments. As an alternative or as an addition to the open technique, ankle arthroscopy allows, beside a good diagnostic visualization of the OCLs, a minimal invasive therapy avoiding the high morbidity of an extensive arthrotomy or malleolar osteotomy. A non-weight bearing cast is attached for 6 weeks and is then followed by a gradual return to weight bearing and athletic activity. Furthermore, hindfoot malalignment (hindfoot varus or valgus) and foot deformity (pes planovalgus, cavovarus, etc.) The defects cause deep ankle pain associated with weightbearing. Osteochondritis dissecans (OCD) of the ankle is the end result of the aseptic separation of an osteochondral fragment of the talar dome with the gradual fragmentation of the articular surface.See the main osteochondritis dissecans article for a general discussion on … 10. A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. 2013 Dec; 8(6): 838–848. 2015 Dec 18;6(11):944-53. doi: 10.5312/wjo.v6.i11.944. This is referred to as an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). Osteochondral Defects of the Talus. Specific changes in the program will be made by the physician as appropriate for the individual patient. As an alternative or as an addition to the open technique, ankle arthroscopy allows, beside a good diagnostic visualization of the OCLs, a minimal invasive therapy avoiding the high morbidity of an extensive arthrotomy or malleolar osteotomy. Jun 17, 2019 Posted by admin Uncategorized 0 comments. Surgical Treatment for Osteochondral Defect. The therapist would probably focus on the quadriceps (a thigh muscle) and especially on the vastus medial;is (part of the quadriceps). The stability of a lesion can be assessed directly with arthroscopy or indirectly with MRI using DeSmet’s criteria. Berndt and Harty2 reported in 1959 that nonoperatively treated patients obtained poor results, and that good results were registered in 84% of the cases after surgical treatment (Level IV). However, medial lesions are more common than lateral OCLs. Osteochondral lesions of the talus encompass a variety of pathological lesions, including osteochondral defects, osteochondritis dissecans, and osteochondral fractures. The ankle joint is composed of the bottom of the tibia bone (shin) and the top of the talus bone (ankle). The top of the talus is dome-shaped and is completely covered with cartilage. In most cases Physiopedia articles are a secondary source and so should not be used as references. Osteochondral tissue harvested from fresh allograft talus and transplanted into the defect Best for large (>3 cm 2 ) lesions, as an alternative to arthrodesis ( 10 ) 66% success rate ( 11 ) These findings are nonspecific because the tenderness could likely be related to joint synovitis instead of an osteochondral lesion. Symptomatic osteochondral ankle defects often require surgical treatment. Terminology. The “classical” defect involves a disruption of both the bone (osteo) and cartilage (chondral) .They usually occur on the Talus if effecting the ankle joint and are a region where the cartilage and underlying bone have been disrupted. Vrije Universiteit Brussel Evidence-Based Practice Project, https://www.physio-pedia.com/index.php?title=Ankle_Osteochondral_Lesions&oldid=241981, exercises to improve flexibility, strength and balance. The arthrotomy may sometimes require a medial or lateral malleolar osteotomy, grooving of the anteromedial distal tibia, or an osteotomy of the anterolateral tibia to reach the involved OCL talus region. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article). What Is the Best Treatment for End-Stage Ankle Arthritis. The SPECT-CT and diagnostic arthroscopy confirmed a lateral talus OCL stage III-IV with cystic lesions (C–F). Int Orthop. Characteristics of Lateral and Medial Osteochondral Lesions of the Talus, An untreated OCL represents a local osteoarthritis model because of the altered joint biomechanics. 1/January 2010 3A. Based on the severity and location of the disease, open surgery and extensive techniques might be applied (mosaicplasty, autologous chondrocytes implantation, and others). Assenmacher JA; Kelikian, AS; Gottlob, C; Kodros, S: Arthroscopically assisted autologous osteochondral transplantation for osteochondral lesions of the talar dome: an MRI and clinical follow-up study. Berndt and Harty, that nonoperatively treated patients obtained poor results, and that good results were registered in 84% of the cases after surgical treatment (Level IV). To best represent the clinical situation we created an osteochondral talar defect. Historically, a variety of terms have been used to refer to this clinical entity including osteochondritis dissecans, osteochondral fracture, and osteochondral defect. Therapeutic arthroscopy with microfracture leads to fibrocartilaginous repair and is an effective treatment of osteochondral lesions of the talus. Ankle sprains are exceedingly common, with >2 million such injuries diagnosed in the United States each year 2. The dimensions of the created defect depth and diameter and the distance between the microfracture holes in this study were scaled down using the respective ratio between a critical-size osteochondral defect in the human (15 mm diameter) and in the smaller goat talus (6 mm diameter) [ 9 , 17 ]. Subsequently, joint fluid pumps into the subchondral bone and creates painful cysts and large-area cartilage lifting. To include all these causes and others, for example, idiopathic osteonecrosis, the term osteochondral lesions (OCLs) provides the most cautious terminology. Ankle injuries are one of the most common musculoskeletal conditions. A review with a podiatrist may also be indicated for the prescription of orthotics and appropriate footwear advice. Articular cartilage has poor regenerative capacity, and the osseous blood supply to the talus is tenuous. Osteochondral Allograft Transplantation. With improved diagnostics, treatment options also changed. Their clinical presentation is described and advice is given on how to diagnose and investigate suspected osteochondral injuries. The diagnostics of OCLs of the talus include first conventional weight-bearing radiographs of the ankle joint, anteroposteriorly and laterally. Because of the still unclear natural history of OCLs, several terms can be found for this entity to date in the literature, for example, osteochondritis dissecans, osteochondral fracture, flake fracture, and others.
