Although the cause of such lesions is unknown, they may involve a genetic predisposition to such a condition. We have found equally good outcomes with the use of autograft and fresh allograft, and therefore use the fresh allograft as our primary option. The damaged cartilage is cleaned out and removed. If the lesion is stable (without loose pieces of cartilage or bone), one or more of the following non-surgical treatment options may be considered: 1. I would recommend starting with the treatment of easy lesions prior to trying the complex and large lesions. There is a great deal of debate as to which adjunct testing is best for diagnosing an osteochondral lesion. Use a cast to allow for healing of the lesion for six to eight weeks. This is very simple to perform and one would make several drill holes into the lesion to allow for bleeding and fibrocartilage formation. If this is not available, the second option is a femoral head fresh allograft. Peroneal Tendon Dysfunction: Why Peroneal Tendon Tears Should Be Treated Like Posterior Tibial Tendon Tears. These can occur from an acute traumatic injury to the knee or an underlying disorder of the bone. In order to protect the soft tissues, one should drill through the medial malleolus with the use of a microvector guide. It is at this point that the patient will present for further consultation. The diagnosis of cartilage damage (osteochondral lesion, also known as talar dome) is often done with x-rays and/or an MRI. Employ CT scanning to check for a solid repair at the six- to eight-week point.

Most of the lesions requiring surgical treatment are posteromedial in location, have poor quality articular cartilage, a loose bone fragment, necrotic bone beneath the lesion, and are poor candidates for healing with internal fixation. In the knee, such cartilage damage can occur between the femur (thigh bone) and the tibia (shin bone). For example, an elite athlete with a large cystic lesion will not do well with drilling of the lesion and may require a grafting of the site. Operative Treatment .

The prevailing thinking is that magnetic resonance imaging (MRI) is better in cases of pure cartilage damage or for superficial lesions while computerized tomography (CT) is better for cystic lesions and lesions that involve both cartilage and bone injury. Such lesions are a tear or fracture in the cartilage covering one of the bones in a joint. It can be challenging to diagnose an osteochondral lesion at the time of injury.
