Demography of Total Joint Replacement Surgeries Performed in a Tertiary Care Hospital: A Cross-sectional Survey

Abstract

Introduction: Total joint replacement of hip and knee is considered as one of the most successful orthopedic surgeries in the twenty-first century because of the only solution to end-stage arthritis of these joints. The real burden of the problem is yet to be established in developing countries like Nepal. This study aims to describe the demographic findings of the joint replacement surgeries among total lower limb surgeries in a tertiary care hospital. Methods: This cross-sectional survey was conducted using the hospital records of 73 total joint replacement surgeries of the lower limb in the Department of Orthopedics of a tertiary care hospital from November 2016 to November 2020. Ethical approval was taken from the Institutional Review Committee (reference number: 077/78-011). Convenience sampling was done. Data analysis was done using the Statistical Package for the Social Sciences version 20. Point estimate at 95% Confidence Interval was calculated along with frequency and percentage for binary data. Results: There were 73 total joint replacement of hips and knees. Of which, 32 (43.84%) total hip replacements were done in which one (3.13%) patient had a simultaneous bilateral hip replacement in single-stage and the other one (3.13%) had two-stage bilateral hip replacement. Forty one (56.16%) total knee replacements were done in which 18 (24.65%) had a simultaneous bilateral knee replacement and five (6.85%) had a unilateral knee replacement. Conclusions: Total joint replacements of the hip were more common among the lower limb surgeries.
