Osteochondrosis dissecans is a local deformative osteoarthritis that can cause swelling and pain in the ankle and knee joints, affecting mobility. Although it cannot be cured completely, symptoms can be alleviated through symptomatic treatment. For those with significant joint deformities, surgical treatment may be considered. Initial symptoms may include weakness in the limbs and abnormal skin sensations, which can be relieved with medication and dietary adjustments.
