Abstract
Background
This study compares outcomes between conversion total hip arthroplasty (THA) after proximal femur fracture (PFF) fixation and primary THA for osteoarthritis and examines whether fracture type affects results.
Methods
This is a retrospective review of prospectively collected data from a single academic center. Eighty-seven consecutive patients underwent conversion THA following surgical fixation of a PFF with a minimum 2-year follow-up. These patients were matched 1:1 with patients who underwent a primary THA for osteoarthritis, by the same arthroplasty surgeons, using propensity score technique. Outcomes measures included length of stay, complications, reoperation rates, and Oxford Hip Score (OHS). Subgroup analysis involved comparing outcome measures between patients who required conversion THA following an intracapsular and extracapsular PFF.
Results
The mean follow-up was 5.6 years (range, 2.3-13.1). Patients in the conversion THA group required longer length of stay (8.1 vs 1.4 days, P < .001). There was no difference in complication rate (12.6% vs 16.1%, P = .491), reoperative rate (12.6% vs 5.7%, P = .243), or OHS (40.1 vs 37.2; P = .052) at final follow-up. There was no difference in outcomes between controls and conversion THA for a previous intracapsular PFF. Reoperation rate was significantly higher (18.2% vs 5.7%, P = .039) and OHS significantly lower (32.3 vs 40.0, P < .001) for conversion THA following extracapsular PFF.
Conclusions
Conversion THA after extracapsular PPF is associated with higher reoperation rates and poorer functional outcomes than primary THA for osteoarthritis. In contract, intracapsular PPF show comparable results, underscoring the need to consider fracture type in treatment planning.
期刊介绍:
Arthroplasty Today is a companion journal to the Journal of Arthroplasty. The journal Arthroplasty Today brings together the clinical and scientific foundations for joint replacement of the hip and knee in an open-access, online format. Arthroplasty Today solicits manuscripts of the highest quality from all areas of scientific endeavor that relate to joint replacement or the treatment of its complications, including those dealing with patient outcomes, economic and policy issues, prosthetic design, biomechanics, biomaterials, and biologic response to arthroplasty. The journal focuses on case reports. It is the purpose of Arthroplasty Today to present material to practicing orthopaedic surgeons that will keep them abreast of developments in the field, prove useful in the care of patients, and aid in understanding the scientific foundation of this subspecialty area of joint replacement. The international members of the Editorial Board provide a worldwide perspective for the journal''s area of interest. Their participation ensures that each issue of Arthroplasty Today provides the reader with timely, peer-reviewed articles of the highest quality.
