Background: Despite some practitioner perception of an inferior outcome in patients with total hip arthroplasty (THA) following hip fracture (HF) vs. osteoarthritis (OA), few studies have analyzed this issue.


Purpose: This cohort study compares characteristics and short-term outcomes in patients with THA following HF and OA during the rehabilitative postsurgical period.


Methods: Records of all consecutive patients admitted in a rehabilitation department of a city hospital for THA, following HF or OA, were reviewed. Outcome measures were the Barthel Index, passive range of motion (PROM) for hip flexion and abduction, and length of hospitalization in the rehabilitation department. Participants were assessed at admission to department and at discharge.


Results: Five hundred seven patients were included (353 in the OA group). The HF group had a longer length of rehabilitation hospital stay and more comorbidity, whereas the OA group had higher functional performances at admission. Both groups improved in all clinical outcome measures with less improvement in PROM abduction scores in the OA group.


Conclusions: Patients undergoing traumatic and elective surgery have distinctive clinical characteristics. Results support the idea that OA patient can have a reduced PROM when compared with HF patients.
