Is Electrocautery of Patella Useful in Patella Non-Resurfacing Total Knee Arthroplasty?: A Prospective Randomized Controlled Study
J Arthroplasty. 2015 Dec;30(12):2125-7124 female patients scheduled for total knee arthroplasty without patellar resurfacing were randomized to undergo the procedure with or without circumpatellar denervation via electrocautery.
