Efficacy of Intra-Operative Periarticular Injections among Patients Undergoing Total HIP Arthroplasty

Abstract

OBJECTIVE: To determine the efficacy of intra-operative periarticular injections (PAIs) among patients undergoing primary total hip arthroplasty. METHODOLOGY: This study was conducted at the Department of Orthopaedic Surgery, Institute of Orthopaedics and Surgery Hospital, Karachi, from June 2021 to December 2022. This quasi-experimental study was done using a non-probability purposive sampling technique. Using the random table method, patients were randomly divided in two groups, i.e. groups A and B. Group A was the experimental group, having 34 patients treated with intra-operative PAI, while group B, also having 34 patients, was the control group. Data was entered and analyzed by the computer program SPSS-25. RESULTS: 68 patients undergoing primary total hip arthroplasty were included; 41.2% (n=28) were male, and 58.8% (n=40) were female. The mean age was 53.53±9.39 years. Efficacy of intra-operative periarticular injection was observed in 60.3% (n=41); in group A, efficacy was 85.3% versus 35.3% in group B (P<0.001). CONCLUSION: Intra-operative periarticular injection therapy is safe, effective and reliable in patients undergoing total hip arthroplasty. Periarticular injections can be safely employed intraoperatively for pain reduction and to achieve optimum functional outcomes to restore hip function, improving these patients' quality of life.
