Functional and radiological outcome of uncemented total hip arthroplasty in young adults - 5 year follow-upollow-up

Abstract

BackgroundEnd stage arthritis in young patients requires surgical intervention. THA remains the treatment of choice for restoring function and activity in end stage hip arthritis. The medium term outcome of uncemented THA in Indian population is less studied. Hence this study was taken up with aim to study clinical and radiological outcome of uncemented THA in patients with age less than 40 years. MethodsThis study was conducted during January 2013 to December 2013. Overall 66 patients with 74 arthritic hips were operated by single surgeon (1st Author) with Uncemented THA. All patients were either unilateral or bilateral arthritis of hip less than 40 years of age. Patients were evaluated preoperatively and postoperatively. After discharge patients were followed up at regular intervals. Activity level and Harris Hip score was calculated. Radiological evaluation was done with anteroposterior and lateral X-rays. ResultsTotal 50 patients (56 hips) followed up at five year follow-up. Clinical and radiological evaluation was done during follow-up. Most common etiology was avascular necrosis of hip (56.6%). None of the patients had any major complications. Mean Harris Hip score improved from 36 to 92. The activity level was assessed at five year follow-up with maximum patients in moderate manual labor category. Bony ingrowth with no evidence of loosening was seen consistently both on femoral and acetabular side in all patients on X-ray. No statistically significant association was found between initial alignment of the femoral component and clinical outcome ConclusionUncemented THA can be used in young patients with excellent to good functional and radiological outcome at midterm follow-up, high satisfaction rate and lower rate of complications.
