Background: Prolonged lateral instability of the ankle after ligament injury has been believed to be a major cause of osteoarthritis of the ankle, yet the rate of development of osteoarthritis of the ankle is relatively low. Clarifying the relationship between patient factors and chondral damage of the ankle with prolonged instability is essential to identify the important risk factors underlying osteoarthritis of the ankle.
Methods: Arthroscopic examination was performed to assess the condition of the articular cartilage in a series of patients with prolonged lateral instability of the ankle.
