S-curved Skin Incision (length 15 cm): The proximal incision is located at the medial border of the patella and then passes through the midpoint of the patella. The distal incision starts from the midpoint of the patella and extends 2 cm laterally towards the tibial tubercle, followed by a medial parapatellar approach to expose the bone. The ImageJ software was used to measure the extent of bone exposure in both the extended position and at 90-degree flexion
