Abstract: Background: Total hip arthroplasty (THA) relieves pain and functional disability experienced by patients with moderate to severe osteoarthritis of the hip, and it improving their quality of life. Relieve of the pain, while maintaining both mobility and stability of the joint are the indicator of success of THA. The purpose of this study was to evaluate the results of primary cementless total hip arthroplasty in patients with posttraumatic osteoarthritis hip.
Methods: Thirty-eight patients with posttraumatic hip Osteoarthritis that were treated with cementless total hip arthroplasty were included in the study. This was a prospective study with the mean follow-up period was 54 months (range, 48 to 72 months). The pre-operative and post-operative pain and functional status was compared using Harris hip score.
Patients: Thirty-eight patients (26 males, 12 females) with mean age of 36 years (range 31 to 46 years) with 16 patients fracture neck femur, 14 patients with malunited fracture acetabulum and 8 patients with fracture head femur. From all twenty-four had avascular necrosis of the femoral head (AVN) were operated on in the period from January 2009 to May 2017. Unilateral cementless total hip arthroplasty was performed in all patients. Indications for surgery were severe pain and loss of function in the hip. Plain X-ray was used for the diagnosis in all cases, and CT scan was needed in cases of acetabular fractures.
Results: The mean Harris Hip Score was 80 that was improved from 38 (preoperatively) to 93 (3 years postoperative). Ten patients had excellent, Twenty good, Five fair, and three patients with poor score. Improvements were seen in the range of motion in all patients as compared to preoperative range.
Conclusion: The management of posttraumatic arthritis of the hip in young and active patients continues to be a difficult challenge. Results of cementless hip Arthroplasty are good and encouraging in treating this group of patients.
