Three cases of the patellar tendon rupture were reported. Case 1 was patellar tendon rupture with avulsion fracture of the patella, and treated by McLaughlin's method. Case 2 was rerupture with avulsion fracture of the patella, and treated by sutures and augmented by artificial ligament (Dacron). Case 3 was patellar tendon avulsion from both patellae and tibial tuberosity which was repaired with sutures though the drill hole.
