A Randomized Controlled Trial Evaluating Functional and Clinical Outcomes and Pain Scores Following Patellar Denervation in Total Knee Replacement Surgery

Abstract
Background: Total Knee Replacement is the treatment of choice of end-stage knee osteoarthritis. Anterior knee pain (AKP) after TKR could negatively affect patient satisfaction and knee function. AKP has been reported in 4% to 49% of patients undergoing primary TKR with no patellar resurfacing, so this study aimed to evaluate the functional and clinical outcomes and pain scores after patellar denervation in total knee replacement surgery. Aim: is to evaluate the functional and clinical outcomes and pain scores after patellar denervation in total knee replacement surgery at the department of Orthopedic Surgery and Trauma, Suez Canal University Hospital, Ismailia, Egypt. Subjects/Materials: this study included 24 patients divided into 2 groups (PD group and NPD group) who met specific inclusion criteria and data collection involved preoperative assessment, operative measures, post operative care and follow up. Methods:The study was Prospective Randomized controlled study which evaluated functional and clinical outcomes and pain scores following patellar denervation in total knee replacement surgery. Results: The PD group consistently has higher OKS scores compared to WOMAC scores at all follow-ups compared to the non-PD group.The PD group exhibited significantly higher Patellar Scores (PS) compared to the non-PD group at 3 months follow-up. Conclusion: Patellar denervation appears to be a valuable adjunct to total knee replacement, providing better functional and clinical outcomes and less pain compared to non-denervation approaches.
