A prospective randomised controlled study in patients undergoing patelloplasty in total knee replacement with coagulation diathermy and without coagulation diathermy

Abstract

Anterior knee pain in the patella femoral area after TKA has been addressed in a growing number of studies. Picetti et al. reported that anterior knee pain was present in 29% of the knees after TKA without patellar resurfacing. Unfortunately, many aspects of anterior knee pain after TKA have yet to be fully understood. This was a prospective randomized control study conducted in patients undergoing patelloplasty in TKA to compare the outcomes with and without coagulation diathermy. In the present study it was observed that 78 % patients with denervation had excellent satisfaction compared to 54 % with no denervation. 14 % patients with denervation had good satisfaction compared to 26 % with no denervation and 8 % patients with denervation had fair satisfaction compared to 20 % with no denervation.
