Step 4, in the step 3, inserting the pre-patellar stripper (22) from the incision on the other side of the distal end of the patella, penetrating the pre-patellar stripper out from the incision on the opposite side of the proximal end of the patella, penetrating the steel wire (32) at the incision on the proximal end of the patella through the steel wire channel (21), withdrawing the pre-patellar stripper (22), and taking the steel wire (32) out from the incision on the other side of the distal end of the patella, wherein at the moment, the two ends of the steel wire (32) are respectively positioned at the two incisions on the distal end of the patella;
and 5, threading one end of the steel wire (32) from the side distal incision to the distal side incision along the deep surface of the patellar ligament, and tightening and cutting the steel wire (32).
