Abstract:

Objective According to the anatomy around the patella, the clinical effect of peripatellar electrocautery denervation in total knee arthroplasty (TKA) was investigated. Methods Eighty-two patients diagnosed with osteoarthritis (91 knees) were included, and bilateral or unilateral TKA without patella replacement was performed. Patients were divided into two groups according to the method of randomized controlled trials. A total of 41 patients (45 knees) in the experimental group received peripatellar denervation during total knee replacement, while 41 patients in the control group (46 knees) did not receive this treatment. All surgical operations were performed by the same orthopaedic surgeon using the same knee prosthesis system. The main evaluation items included knee KSS score, Western Ontario and McMaster Universities (WOMAC score), Feller patella score and VAS score. Results All of the 82 patients were followed up postoperatively, the average follow-up time was 12 months. knee patella KSS score, WOMAC, Feller score and VAS score in the two groups of patients had no significant difference (P>0.05). Conclusion It is considered that circumpatellar denervation in TKA cannot significantly improve the prognosis of patients.
