Radiographic features Osteochondral fractures appear as a combination of 1-2: fracture line extending to     - with knee flexion, the anterior and central face of the medial femoral can be palpated (as opposed to the posteromedial joint 1959. The articulation of the talar dome and the trochlear surface (tibia and fibula) supports the weight of the body. (Some clinicians advocate early weight bearing in milder type-I and II lesions). Vol 36(9); 1050-1057. The authors of the narrative review propose that... MORE, in Diagnose & Treat, Musculoskeletal injuries, Andrew Hamilton looks at new evidence identifying key biomechanical characteristics of running gait that can predict injury in recreational runners, and how to use this knowledge to reduce injury risk.     - role of allografts in repairing chondral defects: (see allografts); J Bone and Joint Surgery.     - classification  Osteochondral lesions (OCL) of the talus are defined as any damage involving both articular cartilage and subchondral bone of the talar dome. Osteochondral fractures involve are an articular surface injury involving the articular cartilage and the subchondral bone plate. The original surgical Outerbridge classification is based on size of surface fragmentation and fissuring. Excision and curettage of the cartilage rim, with packing of particulate juvenile cartilage. Definitions • Osteochondral lesion of talus (OLT): • Only 0.09% of all fractures and 1% of all talus fractures – Traumatic etiology – Commonly: ankle sprain • Inversion injury • 6.5 per 100 ankle sprains – Bosien et al. Most injuries occur due to training errors, such as too much chronic load or increasing acute load too rapidly(1). Each surgery type has its own defined rehabilitation protocol. 2003, 8, 73-90. There are two main staging classifications used; one is determined by MRI diagnostic imaging while the other is determined arthroscopically. The potential surgical options for OLT are quite exhaustive and beyond the scope of this article. Skeletal Radiol (2012) 41:387-399. Autologous chondrocyte implantation – implant of a cultured periosteal patch. Since then, however, OLTs are more commonly referred to by other names such as osteochondritis dissecans, talar dome fracture, and flake fracture. 5.1 Main locations of osteochondral ankle defects Fig. A prospective study                    - Articular cartilage lesions in 993 consecutive knee arthroscopies. We strip away the scientific jargon and deliver you easy-to-follow training exercises, nutrition tips, psychological strategies and recovery programmes and exercises in plain English. Fissuring is … A Study of 5233 Knee Arthroscopies.           - references: Osteochondral defect is a broad term that describes the morphological change of a localised gap in the articular cartilage and subchondral bone 5.     - natural history: Symptomatic osteochondral ankle defects often require surgical treatment.                  improve the microscopic appearance of overlying articular cartilage; Running is beneficial for general health, and while some runners train to compete in race situations, more runners are recreational who run mainly for fitness... MORE, Chris Mallac investigates the causes, diagnosis, and management of navicular stress fractures in athletes. Talar dome injuries such as osteochondral lesions of the talus (OLT) can occur following an ankle injury, resulting in ongoing residual ankle pain and functional disability. Sports Injury Bulletin brings together a worldwide panel of experts – including physiotherapists, doctors, researchers and sports scientists.                  - technical involved insertion of a BMP laden collagen sponge into a chondral defect; He founded Orthopaedic Specialists of North Carolina in 2001 and practices at Franklin Regional Medical Center and Duke Raleigh Hospital. The classification of OLT depends on the investigation of choice. These are as follows(16): The typical framework for conservative treatment is as follows(16): Logically speaking, a patient with an acute ankle sprain that may have an OLT of significance will most likely be in a degree of pain and discomfort.
