A rare cause of chronic hip pain: Intraarticular synovial chondromatosis

A 23-year-old male patient presented to our clinic with pain and limited motion in the right hip. The pain started about 3 years previously and increased over time, spreading to the trochanteric region of the right hip and the right groin. The characteristic of the pain was mechanical. He did not feel pain while sleeping. Prolonged sitting or standing caused the hip to lock. Previously, he had received physical therapy and analgesic medications but there had been no significant improvement. There was no pain in any other joint, and there was no history of disease or trauma associated with the hip. Physical examination revealed an antalgic gait. Palpation of the iliopsoas muscle caused pain. The motion of the right hip joint was limited and painful in all directions, whereas lumbar and left hip joint motions were unrestricted and painless.
