ABSTRACT
Introduction: The cemented total hip athroplasty (THA) has been in existence for about three decades; however, objective outcome analysis of patients subjected to this procedure in India is lacking. At Joint Replacement Centre, Military Hospital (MH), Kirkee, Pune, Maharashtra, India, a large database of total hip arthroplasties exists. The cemented hip arthroplasties are being done regularly at MGM Medical College & Hospital, Kamothe. However, the functional results of cemented hips operated from 2003 to 2015 have been analyzed to assess the objective outcome. Materials and methods: A prospective and retrospective study of 100 cemented hips in 92 patients between 26 and 78 years of age was carried out. Sixty-one (74%) patients were in the age group of 50 to 70 years. The diagnosis of these patients was avascular necrosis: 40; rheumatoid arthritis: 15; ankylosing spondylitis: 8; osteoarthritis: 12; fracture neck femur: 16; and fracture femoral head: 1. In all patients, cemented THA using Indian Orthopedics (INOR) indigenous and Zimmer implants were done. Three types of implants were used, Charnley 22 mm head, 26 mm head using INOR modular system and collarless polished tapered Zimmer system. Eight cases had bilateral involvement. The cases were followed up for varying periods from 1 to 10 years. Results: The results were assessed by utilizing Charnley activity and pain score. There were 83% excellent, 8% good, 5% fair, and 4% poor results. Three cases required revision, two because of frank loosening, and one due to acetabular malpositioning. Charnley pain score improved from 2.2 preoperatively to 5.2 postoperatively (+ 28.3% change). Conclusion: The cemented THA is an excellent salvage procedure for advanced hip disorders resulting in pain and disability, especially in late age groups beyond 50 years.
