Functional outcome of uncemented total hip arthroplasty in degenerative arthritis of hip

Abstract

Background: Total hip replacement is the most commonly performed adult reconstructive procedure. The most common condition for which total hip arthroplasty is done is severe osteoarthritis of the hip, accounting for 70% of cases. This procedure is indicated primarily in patients with severe pain and limitation in activities of daily living. To warrant doing Total hip replacement, pain must be refractory to conservative measures such as oral nonsteroidal anti-inflammatory medication, weight reduction, activity restriction, and the use of supports such as cane.Objectives: To assess the functional outcome of uncemented total hip arthroplasty in patients with degenerative arthritis of hip, in terms of Pain relief, functional capacity, range of motion, absence of deformity, radiological assessment and comparing pre- operative and post-operative functional status with modified harris hip scoring system and to record any complications peri-operatively and in early post-operative period.Methods: This is a prospective study conducted on 34 hips of 30 degenerative arthritis patients who underwent uncemented total hip replacement performed in the Department of Orthopaedics, Sanjay Gandhi Institute of Trauma and Orthopaedics, Bengaluru during November 2018 to March 2020. The patients were followed up at 6,12 and 24 weeks postoperatively and the functional outcome was evaluated using modified harris hip score.Results: 34 hips of 30 patients, with degenerative arthritis were operated with uncemented THR. Patients were evaluated functionally and radiologically. Functional evaluation with modified harris hip score showed excellent results in 27 patients and good result in 3 patients. Radiological evaluation at the last follow up showed no signs of loosening or implant failure.Conclusion: We have evaluated Total hip arthroplasty, using uncemented prosthesis in a short duration follow up. Our study suggests that the current generation of uncemented prosthesis used in the total hip replacement for degenerative arthritis of hip, provides satisfactory clinical and radiological outcomes after a short duration of follow up. Even though the study was not free of complications, the overall functional and radiological outcome showed excellent results.
