Trajectory of Recovery Following Total Ankle Arthroplasty Using Patient-Reported Outcomes Measurement Information System (PROMIS)

This study demonstrates that patients who underwent primary TAA have improvements in PROMIS scores at several different time points up to 1 year after surgery. Patients can expect an improvement in pain and function from baseline within 3 months from surgery. Most improvements occur within the first 6 months. More than half of the patients will achieve a PF and PI score within 1 SD of the national average by 6 months, but it can take up to a year for most patients to reach this. Understanding the trajectory of patient recovery at different time points after primary TAA can help set patient expectations and guide intervention.
