Short term outcome of primary hip osteoarthritis treated with total hip arthroplasty in adults

Abstract

Introduction:In 1961 Sir John Charnley demonstrated the use of steel, plastics and cement to conquer the hip joint, ending the dread associated with the ' hip disease'. A new era of orthopedics had begun. There has been continuous evolution of total hip arthroplasty over last four decades throwing up newer forms of prosthesis from cemented to hybrid to cementless. Inspite of few drawbacks, total hip arthroplasty has emerged by far the popular choice among orthopaedic surgeons to tackle common or complicated hip pathologies and today most commonly performed hip reconstruction procedure. The present study aims to evaluate the results of cement less total hip replacement arthoplasties and to compare the results with other standard series. Aim: To evaluate the results of cement less total hip replacement arthoplasties and to compare the results with other standard series. Materials and Methods: The present prospective study was carried out on 30 patients of either sex or varied age groups having various hip disorders who were admitted during the year 2013-2014. The surgical approach for all the patients enrolled in the current study remained the same i.e Modified Gibson (Modified by Marcy and Fletcher) approach. Patients were followed up every month for the first 6 months followed by quarterly visits thereafter. The follow ups included proper clinical evaluation and roentgenographic evaluation. Results and discussion: We obtained 100% excellent overall results in our series which are comparable to a similar larger series done at the department of orthopaedics, university of Innsbruck, Austria which included 71 primary cementless hip arthroplasty using porous coated press fit acetabular cups which were combined with 61 cementless stems and 10 cemented stems with an average follow up of 2.4 years. However Coventry et al had reported 83% overall good to excellent functional results in their series while, Charnley had found it to be 91% in his series. Thus, our results were consistent with the standars series available in literature. Conclusion: We conclude that the operative treatment for various hip disorders in the form of cementless total hip arthroplasty has helped in alleviation of intractable pain, early rsumption of ambulation and return to functional activity.
