Evaluation of results of primary cementless total hip arthroplasty in osteoarthritis

Abstract

Background: Total hip arthroplasty involves removal of diseased bone and soft tissue from both femoral and acetabular side and replacing it with mechanical components. It is one of the most successful surgical procedures. It relieves pain and functional disability experienced by patients with moderate to severe osteoarthritis of the hip, improving their quality of life. The success of THA is its ability to relieve the pain, while maintaining both mobility and stability of the joint. The purpose of this study was to evaluate the results of primary cementless total hip arthroplasty in patients with hip osteoarthritis.Methods: This study was done in a tertiary care teaching hospital. Thirty patients with hip osteoarthritis who were treated with cementless total hip arthroplasty were included in the study. This was a prospective study with a minimum of 12 months follow up (maximum of 25 months). The patients’ pre-operative and post-operative pain and functional status was compared using Harris hip score.Results: Excellent or good pain relief and function was obtained in 83.33% of cases. The mean total pre-operative Harris Hip Score was 32.93 which improved to 88.967 post-operatively. There was a statistically significant improvement in all parameters except absence of deformity. The most common complication was persistent anterior thigh pain that occurred in two patients.Conclusions: Our study suggests that the current generation of cementless implants provide satisfactory clinical and radiographic outcomes. Though the study was not free of complications, the overall clinical and radiological outcome showed encouraging results.
