Clinical outcome and magnetic resonance imaging after osteochondral autologous transplantation in osteochondritis dissecans The results of a physical examination can vary as there is no specific test to diagnose an osteochondral lesion. Osteochondral defect or Cyst. 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. Figure 1 Relevant Anatomy for an Osteochondral Lesion of the Talar Dome Therefore, we decided to research the 15 best ankle braces and supports available out there in the market. Ankle injuries are one of the most common musculoskeletal conditions. MRI provides complementary information, for example, the status of the OCL overlaying cartilage, information on bony edema, and the situation of the ligaments. Traditional Methods to Ankle Cartilage Replacement. The Berndt and Harty classification has the advantage of being popular, but it does not accurately reflect the integrity of the articular cartilage. Badekas T, Takvorian M, Souras N. Treatment principles for osteochondral lesions in foot and ankle. If your symptoms are not relieved with non-surgical treatment options, you might need surgery. The probe is used to elevate the unstable cartilage around the base and within the perimeter of the osteochondral defect (Fig 5). To best represent the clinical situation we created an osteochondral talar defect. However, it can be subdivided into a traumatic and nontraumatic cause. It is often associated with a traumatic injury such as a severe ankle sprain. Park, HW. Lastly, diagnostic ankle arthroscopy remains a reliable diagnostic tool, allowing direct and dynamic examination of the talus OCLs and the ankle-stabilizing ligaments.14. Osteochondral Defect (OCD) Rehabilitation Protocol . Osteochondral ankle defects(OCD): Symptoms & Treatments. 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). Radiographs further provide information on possible osseous predisposition for CAI, which represents a possible causative factor of OCL in the ankle joint. This article describes the etiology and pathogenesis of these injuries. At the end, OCL fragments can break off and dislocate all over the joint. VALDERRABANO, MD, PhD, ANDRÉ LEUMANN, MD. TABLE 71-2 Treatment Options for Osteochondral Lesions of the Talus with Tissue Repair Potential (Cartilage and Bone), TABLE 71-3 Surgical Principles of Osteochondral Lesions of the Talus, Evidence-Based Orthopaedics The Best Answers to Clinical Questio.

An osteochondral injury to the talar dome produces pain at the ankle and you will find walking and other weight bearing activities difficult. Foot Ankle Int. Verhagen RA, Struijs PA, Bossuyt PM et al (2003) Systematic review of treatment strategies for osteochondral defects of the talar dome. Ankle fusion is also used in some cases, if the talus is very badly damaged. Fibrocartilage grouting, stimulated by abrasion arthroplasty or sharp curettage at the base of the defect, completes the new … 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. Patients with OCLs of the talus typically report chronic ankle pain, joint stiffness, ankle swelling, snapping, giving way, and weakness. MRI is the gold standard for OCL diagnosis, providing information about bone bruise, cartilage status and soft tissues. 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. Further inversion ruptures the lateral ligament and may cause avulsion at its attachment (stage II), which may become completely detached, but remain in place (stage III) or be displaced by further inversion (stage IV). 31, No. the talar dome) in the ankle. Osteochondral lesions may also involve the talar dome, most frequently the medial aspect. Osteochondral injury (or osteochondral defect) of the ankle is an injury to the bone or smooth cartilage covering the joint surface in the ankle. 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). An additional description of identifying whether the lesion is contained or not contained (shoulder) may also be included. The SPECT-CT and diagnostic arthroscopy confirmed a lateral talus OCL stage III-IV with cystic lesions (C–F). Further diagnostic was performed using the single-photon emission computed tomography-computed tomography (SPECT-CT; combination of scintigraphy and CT) (C–E). The patients, usually of young age (mean age in a meta-analysis on 734 patients, 26.9 years),12 are substantially limited in their daily life, in their sports activities, and have a reduced sports level. 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 New and improved video with voice-overs from Consultant Orthopedic surgeons Mr. Simon Moyes and Mr. Omar Haddo. The stability of a lesion can be assessed directly with arthroscopy or indirectly with MRI using DeSmet’s criteria. Trauma plays the most important role in the pathomechanism of talus OCLs. In most joints of the foot and ankle, this layer of cartilage is one to a few millimetres thick. 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. If a cartilage defect is too large for an autograft, an allograft may be considered. Their clinical presentation is described and advice is given on how to diagnose and investigate suspected osteochondral injuries. An OLT can be described as chondral (cartilage only), chondral-subchondral (cartilage and bone), subchondral (intact overlying cartilage), or cystic. The top of the talus is dome-shaped and is completely covered with cartilage. Currently, six characteristics are used to categorise a particular lesion. Ankle sprain is the most common medical history noted by patients. Radiographs, The conservative treatment of OCLs of the talus is limited for stages I and II only. Radiographs (A, B) showed a suspicious area on the lateral talar dome. 31, No. Surgical Treatment for Osteochondral Defect. It is believed that nearly one-half of these sprains will cause a chondral injury 3. 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. Clinical examination should document patient history and include physical examination. 1/January 2010, 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. Ankle sprains are exceedingly common, with >2 million such injuries diagnosed in the United States each year 2. At the initial physical evaluation following injury, the dorsolateral aspect of the talus should be examined for tenderness. 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. 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. A review with a podiatrist may also be indicated for the prescription of orthotics and appropriate footwear advice. Based on the severity and location of the disease, open surgery and extensive techniques might be applied (mosaicplasty, autologous chondrocytes implantation, and others). X-ray, CT scan, MRI or a review by a specialist who can advise on any procedures that may be appropriate to improve the condition. Epidemiologically, the ankle registers 4% of all the human osteochondral defects. J Bone Joint Surg (Br) 2007; 89(6):772 -777. Information from your Foot and Ankle Osteochondral Defect Surgeon in Orange County with offices in Newport Beach and Irvine – Southern California. The ankle may demonstrate acute injury with swelling and ecchymosis or it may appear completely normal, as is often the case with delayed presentations. Osteochondral lesions (OCLs) are focal articular injuries of the subchondral bone and the cartilage with a multifaceted cause (trauma, ligament instability, ischemic necrosis, malalignment, endocrine diseases, and others). Finally, although no accepted definition of lesion size exists, OLTs can generally be considered as either small or large based on their cross-sectional area or greatest diameter (area greater than or less than 1.5 cm² or diameter greater than or less than 15 mm).[3][4][5]. Increased cyst formation compared to images of 2011, but diminished bone oedema. 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). [6][2] Younger people have a higher incidence of trauma history and the lesion size is usually larger as they are exposed to more diverse sporting activities. Slight increase in degenerative changes of the ankle with limited cartilage damage of anterior distal tibia. X-ray and CT’s are also valuable, but rather to rule out fractures and for the detection of subchondral bone injuries. Osteochondral Defect (OCD) Rehabilitation Protocol . Surgery to treat an osteochondral ankle lesion is a series of steps that usually starts with the least invasive technique, an arthroscope, as the last step of diagnosis before your surgeon progresses with whatever needs to be done to repair the top of your talus. 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. Hale S, Hertel J, Reliability and Sensitivity of the Foot and Ankle Disability Index in Subjects With Chronic Ankle Instability, J Athl Train. Combinations of the different graft sizes are used to allow a greater filling rate. Symptomatic osteochondral ankle defects often require surgical treatment. Chapter 71 What Is the Best Treatment for Ankle Osteochondral Lesions? 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 injuries are a possible cause of continued ankle pain after a sprain. 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 ]. Your ankle joint is made up of the top of the ankle (talus) bone and the bottom of the shin (tibia) bone. 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. Platelet-rich plasma is significantly better than hyaluronic acid. Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare provider. OCLs are known to have a significant impact on patients’ quality of life and sports activity, or even their sports careers. Total lesion size unchanged. On images it is easy to see the extent of damage to the surface of the cartilage. Active Ankle Dorsiflexion (foot up) and Plantarflexion (foot down) Move foot up and down (1 repetition) Repeat 20 times over 60 seconds. Osteochondral lesion of the talus, (cartilage damage of the ankle) can occur from a traumatic fracture or ankle sprain when the bones in the ankle joint hit each other damaging the cartilage surface. 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. Their clinical presentation is described and advice is given on how to diagnose and investigate suspected osteochondral injuries. Hereby, a traumatic osteochondral defect (flake fracture) or pathologic chronic shear forces (CAI11) cause damage of the superficial layer of the cartilage, and with time deep cracks and degeneration of the cartilage. Specific changes in the program will be made by the physician as appropriate for the individual patient. Foot Ankle Clin 8:233–242 PubMed CrossRef Google Scholar. 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. [15] Stage 1,2 and 3 lesions are less likely to progress to arthritis and do well with non-operative management. Because currently there is no proof for an underlying inflammation, the traditional term osteochondritis dissecans introduced by König1 in 1888 should be abandoned. Osteochondral lesion of the talus. A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. In the ankle joint, OCLs are mostly seen in the talus, at the posteromedial and anterolateral talar dome, closely related to the top of the curvature. Patients may report ankle sprain or CAI. should be checked. OCLs are articular injuries of the subchondral bone and the overlaying cartilage. An osteochondral ankle defect involves the articular cartilage and subchondral bone (usually of the talus) and is mostly caused by an … Diagnosing, planning and evaluating osteochondral ankle defects with imaging modalities World J Orthop. Overall, more than 80% of the talus OCLs are of traumatic origin. Jun 17, 2019 Posted by admin Uncategorized 0 comments. In many cases, a causative agent cannot be traced and remains “idiopathic.”, TABLE 71-1 Characteristics of Lateral and Medial Osteochondral Lesions of the Talus. With CT, the stages described by Berndt and Harty can be better defined, OCL cysts and fragments better visualized, and the integrity of the subchondral bone better analyzed.

A high level of suspicion is needed with continued pain and disability. Many of them lose their sports career or even jobs by disability. MRI provides complementary information, for example, the status of the OCL overlaying cartilage, information on bony edema, and the situation of the ligaments. Here’s a list of the 15 best ankle braces and supports for all kinds of injuries: Zamst A2-DX Ankle Brace.
