A Prospective Study on Assessment of Quality of Life in TKR Patients Using Sf-36 and Koos-12 in a Tertiary Care Hospital

Abstract

Introduction: Total Knee Replacement (TKR) is a surgical procedure designed to relieve pain and restore function in severely diseased knee joints. The primary indication for TKR is osteoarthritis, rheumatoid arthritis and post-traumatic arthritis. Patients typically report significant improvement in symptoms postoperatively, including a reduction in pain and an increase in mobility. The procedure has evolved significantly over time, with advancements in surgical techniques, prosthetic designs, and postoperative rehabilitation contributing to improved outcomes. The success of TKR depends on careful patient selection, surgical expertise, and the individual's adherence to a rehabilitation program.

Aim: To assess the quality of life in TKR patients using SF-36 and KOOS-12.

Materials: A prospective observational study was carried out in a 450 bedded tertiary care hospital by collecting data from patient case sheet and patient medication interview. The study subject involves 86 patients in orthopaedics who had undergone TKR surgery.

Result:  A total of 100 patients were enrolled in the study including 83 Females and 17 Males. The data obtained upon completion of all phases of the study using SF-36 and KOOS-12 affirms that there is significant improvement in the pain, function and QOL of patients in which both scores agree upon. As well as social and emotional enhancement postoperatively assessed using SF-36 score. The improved QOL of patient with adherence to physiotherapy also affirmed that TKR is a highly successful surgical intervention.

Conclusion: The study measured patient specific factors affecting overall QOL outcome and demonstrated that along with the preoperative assessment and proper postoperative rehabilitation leads to successfully maximized QOL using SF-36 and KOOS-12 questionnaires.
