Patients with Osteoporosis Are at Higher Risk for Periprosthetic Femoral Fractures and Aseptic Loosening Following Total Hip Arthroplasty.

This report provides an updated analysis for patients with osteoporosis following total hip arthroplasty (THA). The comorbidities of alcohol abuse, chronic kidney disease, cerebrovascular disease, obesity, and rheumatoid arthritis continue to be significant risk factors for periprosthetic femur fracture (PPFFx) and aseptic loosening in the population with osteoporosis. Patients with dual-energy x-ray absorptiometric (DEXA) scans were at risk for PPFFx regardless of femoral fixation method, and patients with DEXA scans with cementless fixation were at risk of aseptic loosening after THA. The patient population with severe osteoporosis may have higher risks for aseptic loosening and PPFFx than previously recognized.
