Long-Term Outcomes of Functional Cup Positioned Total Hip Arthroplasty in Asian Ankylosing Spondylitis Patients

Primary THA in AS patients demonstrated favorable survival at 10 years but poor long-term survival. Functional cup positioning demonstrated excellent results in terms of minimizing dislocation. Cemented implants had greater risk of aseptic loosening in long term, but differences were minimal considering all-cause revision.
