AI Article Synopsis
- Patient-reported outcome measures (PROMs) are used to assess recovery and satisfaction in patients after total hip arthroplasty (THA), aiming to understand the trajectory of recovery over the first year.
- In a study with 1,898 patients, significant improvements were observed in PROMs post-surgery, with the best recovery noted within the first month, while physical activity improvements took longer to manifest.
- The findings suggest that patients can expect the most noticeable improvements in satisfaction metrics within one month, functional recovery by three months, and gait quality to potentially lag until after one year, which can guide patient expectations and care strategies.
Article Abstract
Background: Patient-reported outcome measures (PROMs) are frequently used for evaluating patient satisfaction and function following total hip arthroplasty (THA). Functional measures along with chronologic modeling may help set expectations perioperatively. Our goal was to define the trajectory of recovery and function in the first year following THA.
Methods: Prospective data from 1,898 patients in a multicenter study was analyzed. The PROMs included the Hip disability and Osteoarthritis Score for Joint Replacement and EuroQol-5 dimension. Physical activity was recorded on a wearable technology. Data was collected preoperatively and at 1, 3, 6, and 12 months postoperatively. Generalized estimating equations were used to evaluate outcomes over time.
Results: Significant improvement occurred between preoperative and postoperative time points for all PROMs. The PROMs showed the greatest proportional recovery within the first month postoperatively, each improving by at least 1 minimal clinically important difference (MCID). Daily steps and flights of stairs took longer to reach at least 1 MCID (3 months and 1 year, respectively). Gait speed and walking asymmetry returned to baseline by 3 months, but did not reach a MCID of improvement by 1 year.
Conclusion: Patients can be counseled that the greatest proportional improvement in PROMs is within 1 month after THA, while function surpasses preoperative baselines by 3 months, and gait quality may not improve until after 1 year. This can help set realistic expectations and target interventions toward patients deviating from the norm.
