Summary
Patients undergoing total hip arthroplasty (THA) have similar satisfaction and outcomes regardless of preoperative activity level. Inactive patients experienced greater improvements in physical activity post-THA compared to active patients.
Area of Science:
- Orthopedic Surgery
- Rehabilitation Medicine
- Patient-Reported Outcomes
Background:
- Total hip arthroplasty (THA) aims to relieve pain and restore function, including physical activity.
- Patient expectations regarding return to activity significantly influence their perception of surgical success.
Purpose of the Study:
- To investigate the impact of preoperative physical activity levels on patient expectations.
- To assess postoperative satisfaction and clinical outcomes in THA patients based on their activity status.
Main Methods:
- Retrospective analysis of a THA registry (2007-2012).
- Matched cohorts of active and inactive patients (n=1053 each) based on demographics and comorbidities.
- Utilized validated questionnaires for activity level, expectations, and functional outcomes (HOOS).
Main Results:
- Active patients had higher expectations for returning to exercise and sports (74% vs 64%).
- Higher expectations correlated with better HOOS sports scores in active patients.
- Inactive patients demonstrated greater improvement in physical activity at 2 years compared to active patients.
Conclusions:
- Post-THA satisfaction and clinical outcomes are comparable between active and inactive patients at two years.
- Inactive patients show a more significant increase in physical activity levels after surgery.
- Complication and revision rates were similar across both groups.
