Riassunto dello studio

Seventy-three patients with severe primary knee osteoarthritis undergoing total knee arthroplasty were randomized to receive either an individualized intraoperative video showing their postoperative knee range of motion (n=37) or no video (n=36). The primary outcome of interest was range of motion (ROM). Secondary outcomes included the New Knee Society Score (nKSS) components: symptoms, satisfaction, expectations, and functional activities. Outcomes were assessed at six weeks postoperatively. Overall, the results of the study revealed no clinically meaningful difference in ROM or most clinical scores between groups. While there were statistically significant differences in preoperative satisfaction (p=0.008) and postoperative function scores (p=0.012), these were not clinically relevant. The study concludes that showing an intraoperative video did not improve early postoperative outcomes.
