Microfracture for Osteochondral Lesions of the Talus: Perspective 1 Hajo Thermann Christoph Becher DEFINITION The terminology of osteochondral lesions is not uniform: Transchondral fractures, osteochondral fractures, flake fractures, and osteochondritis dissecans (OCD) are used to describe the same entity. Symptoms related to this condition are nonspecific including pain, swelling, stiffness, and mechanical symptoms of locking and catching. And in the hip, osteochondral injuries are most often associated with hip dislocation. [] This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. An osteochondral lesion of the talar dome typically occurs during a traumatic injury to the ankle, such as an ankle sprain (particularly involving significant weight bearing forces), a traumatic landing from a height (particularly involving forced end of range ankle movements) or a motor vehicle accident. Injuries that could cause a talus fracture include a fall from a great height or a car accident. Osteochondral lesions (OCL) of the talus are being recognized as an increasingly frequent sports injury. Terminology. ome minor osteochondral defects can heal on their own, without casting or surgery.

Osteochondral lesions are injuries to the talus (the bottom bone of the ankle joint) that involve both the bone and the overlying cartilage. Most patients are scheduled to visit their physician once every four to six weeks until the osteochondral defect heals. Such lesions also may result from high energy trauma, avascular necrosis, infection and iatrogenic causes.

If your physician has determined that this is the case, he may recommend rest and physical therapy while he observes your knee's recovery.

There are two main mechanisms of these fractures, including a direct effect causing avulsion or impaction and, a more common mechanism, flexion-rotation force to the knee, which is also the mechanism for an acute patellar dislocation. The condition occurs most commonly in the knee, but also occurs in elbows, ankles and other joints. The true incidence of osteochondral/chondral fractures in the lower extremity is difficult to determine due to a lack of defined symptoms and radiographic findings at the time of injury. Background: Osteochondral defects represent a main risk factor for osteoarthritis of the ankle. Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. Fig. Keywords: Osteochondral defects, arthroscopic debridement, micro fracture technique, lysholm knee scoring scale Introduction Articular cartilage is a complex tissue with an ability to withstand tremendous forces over many cycles and years, but at the same time it has no ability to heal even after a minor injury. The methods and compositions provide an effective amount of isolated differentiable human Very Small Embryonic Like Stem Cells (hVSELs) sufficient for regeneration or repair of an osteochondral tissue. Osteochondral fracture is a localized injury affecting a surface of the joint that involves breaking, with or without separation, a segment of cartilage and the underlying bone. This can occur in any joint, although it is most common in the knee (especially the kneecap), followed by the ankle, elbow, and shoulder.
