We experienced 3 cases of impingement of the infrapatellar fat pad in the patellofemoral joint after direct injury to the knee. The impingement was confirmed by arthroscopy.At extended position, the fat pad was impinged in the patellofemoral joint, however, at flexed position the impingement disappeared.At arthroscopy we used lateral suprapatellar pouch approach and saline was deflated from the knee joint for observation under biological condition. All cases received conservative therapy. Case 1 received casting with the knee in 30° flexion for 1 week. Case 2 received physical therapy as an in-patient. Case 3 received steroid injection to the infrapatellar fat pad and casting with the knee in 30° flexion for 1 week. In every case, symptom disappeared.
