Abstract

Background: Different approaches for total hip arthroplasty (THA) may offer advantages in regard to achieving same-day-discharge (SDD) success.

Methods: We retrospectively identified patients aged ≥ 18 years who underwent elective primary THA from 2015 to 2020 who were formally enrolled in a single institution's SDD program. A total of 1,127 and 207 patients underwent THA via direct anterior approach and posterior approach, respectively, were included. Cohorts were assigned based on approach. The primary outcome was failure-to-launch, defined as hospital stay extending past 1 midnight. Secondary outcomes included Forgotten Joint Score-12, Hip Disability and Osteoarthritis Outcome Score for Joint Replacement, 90-day readmission and revision rate, and surgical time. Patient-reported outcomes were collected at 3 and 12 months.

Results: After controlling for demographic differences, posterior approach patients had higher rates of failure-to-launch (12.1% versus 5.9%, P = .002) and longer surgical times (99 versus 80 minutes; P < .001) compared to direct anterior approach patients. The cohorts had similar readmission (1.7% versus 1.4%; P = .64) and revision rates (1% versus 1%; P = .88). The magnitude of improvement in Hip Disability and Osteoarthritis Outcome Score for Joint Replacement scores from preoperative to 12 months was similar between cohorts (35.3 versus 34.5; P = .42). The differences in outcome scores between cohorts at each time point were not considered clinically significant.

Conclusion: Our analysis suggests that patient selection and surgical approach may be important for achieving SDD. Surgical approach did not significantly impact readmission or revision rates nor did it have a meaningful impact on patient-reported outcomes in the first year after surgery.
