Mechanical derangements of the knee are an uncommon complication of chronic haemophiliac arthropathy. Two patients with locking of the patella were treated by manipulation. The mechanism of the injury was forced flexion of the knee joint beyond the limit of its restricted range. The injury is a serious one and may take six months to recover.
