Abstract :

Introduction: Total hip arthroplasty is a surgical treatment that has been thoroughly documented. The capacity of Total Hip Replacement arthroplasty to treat pain associated with hip joint pathology while retaining mobility and stability of the hip joint is the key to its effectiveness. The goal of this study was to use the Modified Harris hip score and radiological examination to assess the clinical and functional outcomes of total hip arthroplasty. Materials and Methods: The study was carried out on 33 hips of 30 patients of Total Hip Replacement operated in the Department of Orthopedics, Vinayaka missions medical College and Hospital and Vinayaka missions Hitec Hospital, Salem, from August 2012 to September 2014. This was a retrospective as well as prospective study. Patient follow up was for a minimum of 6 weeks to a maximum of 12 months (1yr). Results: 9 patients underwent uncemented total hip replacement in which for 5 patients the acetabular cup was fixed with 2 acetabular screws each. During the procedure 1 patient had Type A2 Vancouver fracture of the proximal femur which was fixed with SS wire cerclage which united as documented by the follow up X-rays. Postoperatively, for two patients we came across dislocation due to adductor contracture, was reduced following adductor tenotomy. Patients were found to be doing normal daily activities by the follow-up. The mean overall pre-operative score was 33.3, which improved to a mean score of 94.2 after surgery. Dislocation was seen in 2 individual patients. Conclusion: After THR, which was conducted on a population of active individuals, 96.9% of patients experienced excellent or good pain reduction and function. When pain sufferers were included, the overall average score was 90 points, but after a minimum of five years of follow-up of 91 hips treated with the PCA prosthesis, the average score was 93 points.
