THA in patients younger than 30 years has excellent results
Total hip replacement in patients of younger age with higher levels of activity increases the risk of loosening and mechanical failure.

Fifty patients 34 male and 16 (62 hips) with mean age of 24 years received a primary total hip replacement. The etiology for operation was juvenile rheumatoid arthritis in 10 patients, ankylosing spondylitis in 20, and posttraumatic hip arthritis in 20. Cementless total hip replacement was used in 36 patients (42 hips); hybrid (cementless cup and cemented stem) was used in 14 patients (20 hips). Merle d'Aubigne score was used for clinical evaluation preoperative and at the last follow up. DeLee and Charnley criteria of acetabulum were used to assess the acetabular stability. Gruen et al. zones of femoral stem were recoded to monitor loosening.

The mean follow up duration was 9.5 years (range, 7 to 10.5 years). The mean pre-operative Merle d'Aubigne score was significantly improved from 6. 5 (SD 2.34) preoperatively to 16.5 (SD 1.56) 1-year postoperatively (P<0.001). Osteointegration of the stem was noted in 45 cases (57 hips) at the end one year of follow-up. By the end of follow up there were radiolucent lines in two to three of Gruen zones around the stem, and it was progressive in 10 patients without need of revision. Subsidence of more than 5 mm occurred in 8 hips 4 of them had revision and the other 4 were not revised until the end of follow up.Total hip arthroplasty in very patients has an excellent long term results up to 89.7% survival after 10.5 years of follow up.
