Background and purpose - The frequency of progression of osteoarthritis and persistence of symptoms in untreated osteochondral lesion of the talus (OCL) is not well known. Though there is some evidence that the high grade lesions do less well with an arthroscopic debridement and microfracture this is a much smaller operation than open grafting and a number will settle with no more intervention required. A reduced or painful range of motion, mild non-pitting edema and medial or lateral tenderness to palpation may be evident on a physical exam. Talar dome lesions are usually caused by … Thieme, 2006. incidence 69% of ankle fractures; 70% of ankle sprains; 10% are bilateral Treatment of OCL may be operative or nonoperative. Medial lesions are more common than the lateral ones and typically located at the posteromedial talar dome, with a typicall deep - cupshaped figure. 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).Radiography cannot directly depict the cartilage surface ().Both magnetic resonance (MR) imaging and ankle arthroscopy are excellent tools commonly used to evaluate ankle cartilage (3 –5). Osteochondral lesions of the talus can arise from a number of potential causes. Annals of Clinical and Analytical Medicine; inquiry In later stages of the disorder there will be swelling of the affected joint which catches and locks during movement.

Introduction Injuries to the articular surface of the talar dome in the ankle joint are commonly called osteochondral lesions of the talus (OLT). (1999) Foot & ankle international. Pathophysiology of OCLs of the talus : Talar osteochondral lesions tend to involve the medial and lateral corners of the talar dome. 3. 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). pain, later studies showed that 30–43% of talar OCL diagnosed on MRI were invisible on CR [5]. They may also be called osteochondritis dessicans or osteochondral fractures. The aim of this retrospective study was to investigate the clinical state after AM and the MRI outcome. Osteochondral lesions of the talus: a revised classification. Osteochondral lesions (OCL) of the talus involve both articular cartilage and subchondral bone of the talar dome. Revision surgery after failed prior marrow stimulation for large (area >1.5 cm2) or cystic (volume >3.0 cm3) osteochondral lesions of the talus when autografting would be inadequate due to lesion size, depth or location. netic resonance imaging [MRI]), has been targeted as a viable entity to treat in a therapeutic strategy to relieve pain.2 Inhibition of subchondral lesions has been shown to alleviate joint pain.1 Several arthroscopic and open sur-gical techniques have been used to address subchondral disease, including osteochondral autograft and allograft,3 A study by Verhagen and colleagues found MRI has a greater sensitivity in comparison to computed tomography (CT). 3 illustrates the classification of osteochondral lesions of the talus using MRI. 17 The etiology of OLTs is primarily due to damage of the talar articular surface and the subchondral bone. When analyzing osteochondral lesions on MR images of the knee, the radiologist must first consider patient demographics, clinical presentation, and history of trauma. An osteochondral lesion of the talus (OLT) is defined as an injury to the talar dome that results in partial or total separation of the articular cartilage or subchondral bone. Thus, it is an important aid in surgical planning and in follow-ups. 2011 Oct. 4(5):274-9. . It also aids in the assessment of stability and determination of the presence of a cystic component. 3. Other terms that refer to the same general process are osteochondral defects (OCD), osteochondritis dissecans Background Magnetic resonance imaging (MRI) has been used as an optimal technique for evaluating articular cartilage (1, 2).It can provide information about cartilage damage and correlates closely with arthroscopic findings ().MRI has greater sensitivity to cartilage and helps clarify cartilage damage (). Posadzy, M, et al. This condition is also known as either osteochondritis dissecans (OCD) of the talus or as a talar osteochondral lesion (OCL). This condition is also known as osteochondritis dissecans (OCD) of the talus or a talar osteochondral lesion (OCL). 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).Radiography cannot directly depict the cartilage surface ().Both magnetic resonance (MR) imaging and ankle arthroscopy are excellent tools commonly used to evaluate ankle cartilage (3 –5).
