Evaluation of the Functional Outcome of Total Hip Replacement by Anterolateral Approach

Open Access

Abstract

Background: Anterolateral Total hip arthroplasty is gaining popularity for hip arthropathy treatment, as it has potential advantages in preserving muscles and enhancing joint stability. There is a lack of information about functional results for this procedure in Bangladeshi patients. The purpose of this study is to explore functional results for Total hip replacement with an anterolateral approach for diverse hip disorders. Methods & Materials: This was an interventional study conducted at the Bangladesh Medical University, Dhaka, Bangladesh from March 2018 to August 2020. 27 patients aged above 20 years with hip arthropathy needing Total hip replacement were purposively sampled for the study. The operations were done by employing the anterolateral approach with the use of cemented implants under spinal anesthetics. The function was evaluated by the Harris Hip Scores (HHS) and Visual Analogue Scale (VAS) for pain at pre-op and six months post-op, respectively. Data were entered and analyzed using SPSS version 26, with a p-value <0.05 considered significant. Results: The average age was 44.85±12.87 years, and 66.7% of the patients were females. The most prevalent indication was osteoarthritis (51.9%), followed by AVN and femoral neck fractures. The average surgery time was 75.37±8.87 minutes, and the average hospital stay was 6.78±1.34 days. The average Harris Hip Score of 82.78±4.87 was attained at the sixth month. The VAS scores improved remarkably from 4.03±3.04 pre-operatively to 1.07±1.73 post-operatively (p<0.001); 66.7% of the patients got complete pain relief. Radiographic stability was achieved in 92.6% of cases. Conclusion: The anterolateral approach in Total hip replacement offers outstanding functional results with substantial pain relief, high implant stability, and acceptable surgery parameters in the Bangladeshi population, ensuring its effectiveness as a surgical procedure in cases of various hip pathologies.
