Near-Optimal Recovery Within 3 Months: Investigating Health-Related Quality of Life and Functional Outcomes After Single-Stage Bilateral Hip Replacement for Osteoarthritis.

ABSTRACT

Single-stage bilateral hip replacement (SSBHR) is a safe and successful orthopaedic intervention for patients suffering from bilateral osteoarthritis of the hip. Data on short- and mid-term recovery outcome studies are, unfortunately, scarce. The purpose of this study was to investigate the change in the functional measures and quality of life after SSBHR and to determine the patient's willingness to undergo the same procedure again. Data were prospectively collected and analyzed from patients with bilateral symptomatic hip osteoarthritis who underwent SSBHR from January 2019 until December 2020. Patients were excluded only if they failed to sign an informed consent or were unable to fill out questionnaires due to language or cognitive problems. Preoperatively and 3 and 12 months after surgery, health-related quality of life (HRQOL) and physical functioning were measured. Twelve months after surgery, patient satisfaction (willingness to undergo the same procedure again) was obtained. Complications, blood loss, and length of stay (LOS) were abstracted from the clinical notes and the electronic patient files. Patients improved significantly on all domains of HRQOL (16.0%-59.7%) and physical functioning (14.7%-15.8%) 3 months after surgery in comparison with preoperatively. No improvement was reported on HRQOL and physical functioning, except the Timed Up and Go score (14.1%), at 12 months after surgery in comparison with 3 months. No major or minor complications were found, and LOS was 2.9 days on average. One year after the surgery, all patients expressed satisfaction as suggested by their willingness to undergo the same surgical procedure again. Our study demonstrates that SSBHR offers a rapid recovery time and significant improvements in both functional status and HRQOL within 3 months after surgery. These findings can inform healthcare professionals and patients, suggesting that SSBHR is a viable treatment option for patients with bilateral hip osteoarthritis. Further research, including multicenter randomized controlled trials, is recommended to compare the recovery outcomes of SSBHR with two-stage bilateral hip replacement and confirm our findings.
