Cartilage damage (chondral lesions) is increasingly occurring in younger people. One reason for this is ankle joint injuries caused by sprains (distortion), the most common injuries of the lower extremities, and which may lead to ligament injuries and cartilage lesions. Around 50% of patients suffering from fractures of the ankle joint or ligament injuries show damage to cartilage and/or adjacent bone as a consequence.
Repeated injury, chronic tendon instability, and accompanying effects: their causes are as diverse as the problems generated by cartilage damage. In many cases, cartilage or cartilage-bone injuries don't spontaneously recover and, if not diagnosed and treated in time, can lead to ankle joint arthritis.
