Results of Patella Surfacing Versus Non-Surfacing in Total Knee Replacement

Abstract

Objective: To compare the functional outcomes of patients after the procedures by resurfacing and not resurfacing the patella during the surgery, Background: The-total-knee arthroplasty (TKA) - is the-prosthetic-replacement of patellofemoral and the femorotibial compartments with an inert mechanical structure, to enable it to restore functional mobility and indolence, restoring its prior autonomy. TKA has advanced, and with it, the implants and friction torques have improved, ensuring the prosthesis' life and durability. Study Design: retrospective cohort study, Place And Duration: This study was conducted in Liaquat National Hospital and Medical College Karachi from October 2022 to October 2023, Methodology: This study includes 57 patients and 60 knees who underwent TKA. The patients of primary osteoarthritis either primary or traumatic origin were included in the study. The information regarding the TKA like -inflammatory-joint-diseases-and-trauma-history-, -medical and surgical history, primary/secondary gonarthrosis ,the affected side, , -the-surgical-technique, -radiological-assessment (knee-radiograph-the -anterior/posterior -view- and lateral view), -and clinical Knee Society Score (KSS) were recorded. The data was entered and analyzed using SPSS version 26.0, Results: The-BMI-of the patients ranged from 19 kg/m2 to 38 kg/m2(mean and SD= 29.6±1). There were 44 (73.33%) female and 16 (26.67%) male in the study. There were 32 (53.33%) left, 24 (40%) right and 4 (6.67%) bilateral knees in the study. We observed that in resurfaced group, 2 (9.52%) cases observed anterior pain, 3 (14.29%) 1(4.76%) and 1(4.76%) observed infection, limping and stiffness respectively. Average postoperative mobility amplified from 86 to °106.7° with an average increase of 106° and -108° in-resurfaced-cases-and-non-resurfaced-cases respectively. Conclusion: We conclude that the replacement patella is expensive procedure with delayed recovery time. However, there were no any functional differences of functional outcomes across the procedures used in the study. Therefore it is the discretion of the surgeon according to his expertise to opt for the procedure aligned with the condition of the patient.
