hello, Although wearing a brace or cast may ease the discomfort of an osteochondral lesion, they are usually not enough to remedy the problem permanently, except in children, who can respond well to non-surgical treatment
For adults, such a condition usually requires surgery. The type of surgery that is most effective depends on the size, location and severity of the lesion. Most commonly, a surgeon will perform an arthroscopic exploration and treatment. The damaged cartilage
is cleaned out and removed. If the damage is small, the surgeon may drill into the bone, which causes a small amount of bleeding and encourages healing. If damage is extensive, then a bone graft can be inserted to replace the cartilage. For older patients, a knee replacement
may be an option. It is not a preferred option for younger patients, since failure of the knee replacement and the need for revision is more likely in younger patients.
After surgery, weight should be kept off the affected knee or ankle for four to six weeks. In some cases a cast must be worn for part or all of that period. Physiotherapy
is then recommended to rehabilitate the affected knee or ankle. The vast majority of patients experience no pain or swelling even 10 years after surgical treatment of such lesions in the ankle. Treatments for lesions in the knee are more challenging, but also have promising outcomes. Regards,
