Survival and patient-reported outcomes of robotic arm-assisted patellofemoral arthroplasty and patient-acceptable symptom state thresholds

raPFA was associated with clinically meaningful postoperative outcome measures and a high NPS. However, approximately one in five were not satisfied, which was independently associated with increasing comorbidity, and approximately one in 20 underwent reoperation in the first four years postoperatively. The defined PASS thresholds specifically for PFA could be used to help interpret outcomes in future studies.

Abstract

raPFA was associated with clinically meaningful postoperative outcome measures and a high NPS. However, approximately one in five were not satisfied, which was independently associated with increasing comorbidity, and approximately one in 20 underwent reoperation in the first four years postoperatively. The defined PASS thresholds specifically for PFA could be used to help interpret outcomes in future studies.
