Preoperative Pain Sensitivity Has a Greater Impact on Clinical Outcomes Than Coronal Alignment Strategy in Robotic-Assisted Total Knee Arthroplasty

This study aimed to determine whether preoperative pain sensitivity or coronal alignment strategy has a greater impact on patient-reported outcome measures (PROMs) following robotic-assisted total knee arthroplasty (TKA). The findings revealed that preoperative pain sensitivity was a significant negative predictor of PROMs, while the alignment strategy did not influence outcomes, particularly in patients with high pain sensitivity. In contrast, patients with low pain sensitivity experienced better outcomes with functional alignment compared to mechanical alignment.
