Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is a double-blind randomized controlled trial aiming to investigate the effects of patellar denervation using electrocautery on postoperative knee pain and knee function in patients undergoing primary total knee arthroplasty (TKA) without patellar resurfacing.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a prospective, double-blind randomized controlled trial conducted at Queen Savang Vadhana Memorial Hospital between 2023 and 2025. The aim of the study is to assess the effect of patellar denervation using electrocautery on postoperative knee pain and knee function in patients undergoing primary total knee arthroplasty (TKA) without patellar resurfacing.

Sixty-four patients were enrolled and randomly assigned to either the patellar denervation group (PD) or the non-denervation group (NPD), with 32 participants in each group.
