From a healthy man, set. twenty. (Hospital, 24, 121.) Twelve years before entrance he struck the inside of the patella. Severe inflammation followed, but passed off in three or four weeks, and for six months he had no further trouble. The knee then swelled, and the loose body was first felt. From that time he had frequent attacks of pain and swelling, but complained mostly of the loose body slipping between the femur and tibia. The body was cut out, and the patient died with violent local and constitu- tional symptoms on the tenth day.
