The main complaint one Osteochondrosis dissecans are mainly pain in the area of ​​the Talus (usually only one ankle is affected by the pathological process). These can be either on the inside or the outside of the joint. This is often accompanied by joint effusion, which can ultimately lead to swelling of the joint. This often restricts the movement of the joint. Both the extension and the flexion of the Foot impaired. The symptoms increase under stress.
However, these symptoms usually only appear at a very advanced stage. Some patients remain symptom-free throughout the course of the disease. Even so, if it is detected, it should be treated as it poses a risk of osteoarthritis Knee joint increased significantly.


If, after collecting a medical history and physical examination, it is suspected Osteochondrosis dissecans exists, this can be done with the help of a X-ray image be secured. Changes in the joint can be made even more reliable by a Magnetic resonance imaging represent. By far the most common localization for herd one Osteochondrosis dissecans in the ankle are the inner or outer edge of the joint, there are rarely changes in the front or back.


The treatment of osteochondrosis dissecans on the talus is based on the Stage of the diseasein which the patient is located.
Particularly in young patients, spontaneous healing rates of up to 50% can be found in the early stages. Otherwise the therapy is limited to the stages I and II (in which no piece of cartilage or bone has broken off) primarily on sparing the talus and physiotherapy.

When there is no healing or a transition into stage III or IV (if the piece has already come loose), the ankle is first mirrored (Arthroscopy). Depending on the findings, the joint is then drilled (to accelerate the healing process), the broken piece bone or cartilage removed or reattached, or a cartilage-bone graft performed.
