Abstract
BACKGROUND: Total hip arthroplasty (THA) was once reserved for old patients with hip arthritis but has become more common in very young patients (≤25 years old) diagnosed with various joint disease that were not relieved with conservative treatment. The purpose of this study was to evaluate short to mid-term outcome of THA in patients younger than 25 years old. METHOD: This retrospective study included 45 patients younger than 25 years (mean age 21.8 ± 2.14 years) who underwent THA. The surgical indications, implant selection, leg length discrepancy, medication history, radiographic outcome, survival and clinical results including the modified Harris hip score (mHHS) and SF-36 score were assessed. RESULT: The mean follow-up period recorded for patients was 7.82 years (range 5-12 years). The most common diagnosis was avascular necrosis (37.7%) followed by ankylosing spondylitis (24.4%), developmental dysplasia of the hip (17.7%) and rheumatoid arthritis (8.8%). The preoperative leg length discrepancy (LLD), which ranged from 0.5-7 cm significantly improved after surgery ranging from 0-1 cm. The mean preoperative mHHS was 32.44 ± 18.90 compared with the postoperative score of 94.54 ± 5.81 (p < 0.001). The preoperative p-value of SF-36 was lower compared to the postoperative value in all subgroups of SF-36 (p < 0.001). At the latest follow-up there were no radiological signs of loosening and all the implants were classified as well-integrated. CONCLUSION: At present total hip arthroplasty is considered to be safe and a good solution for young patients below 25 years suffering from end-stage joint disease; however, longer follow-up is required to evaluate the long-term function and outcome of the prosthesis in order to restore the normal lifestyle of the patients.
