Application of saphenous nerve infrapatellar branch protection technique in total knee arthroplasty.

ABSTRACT:

Objective

This randomized controlled trial conducted a comparative analysis of postoperative outcomes between a modified anteromedial incision with saphenous nerve protection and the traditional medial parapatellar approach in total knee arthroplasty (TKA). We aimed to test the hypothesis that the nerve-sparing modified technique would significantly reduce postoperative anterior knee numbness and pain while maintaining surgical feasibility.

Methods

Sixty-eight TKA candidates (January 2022-June 2023) were prospectively randomized into two groups: Modified (n = 34) and Traditional (n = 34) approaches. The modified technique featured an anteromedial incision with infrapatellar branch visualization and preservation, whereas the control group received the traditional medial parap
