We aimed to clarify the possibility of using bipolar hip arthroplasty (BHA) for degenerative diseases by examining long-term results postoperatively in 336 hips. Patients' average age was 61.0 years (range, 34-88 years), and the average follow-up period was 12.5 years (range, 5.0-27.3 years). The 5-year, 10-year, and 20-year Kaplan Meier survival rates (end point: revision) were 92.1%, 81.8%, and 20.1% in the osteoarthritis group and 96.4%, 90.1%, and 24.6% in the rheumatoid arthritis group, respectively. Since the survival rate for more than 10 years decreases rapidly, the use of BHA for treating degenerative diseases should be restricted. © 2019 Professor P K Surendran Memorial Education Foundation.
