An isolated defect in the joint cartilage differs from degenerative arthritis because it involves only a limited demarcated section of the joint surface. These lesions can lead to knee arthritis in the long run.

The most common cause is trauma and osteochondritis dissecans.
The patient’s age, activity level, size and location of the lesion and associated problems determine the treatment method.
