Introduction: Postoperative rehabilitation protocols following total knee replacement vary considerably among surgeons. Previous reports have shown the usefulness of music exercise videos for cardiovascular rehabilitation and general fitness. The authors created a music exercise video for use in the postoperative period following total knee replacement.

Methods: A prospective study was done whereby 45 patients undergoing 51 primary total knee replacements were randomized to a control (25) or video (26) group. All procedures were done by the senior author. All patients were evaluated at postoperative week 1,2,4,6, and 8 by a blinded examiner who generated Knee Society scores. Patients also completed a satisfaction questionnaire and the 8 week cost of rehabilitation was documented.

Results: Significant improvements were noted in patient’s assessment of understanding, confidence, and overall satisfaction when using the video (p< 0.05). Average return to usual activities was 34 days in the control and 14 days in the video group (p< 0.0001). Knee Society knee and function scores were improved for the video group and were statistically significant for the 6 and 8 week scores (p< 0.05). The combined Knee Society score at 6 weeks was 141 for the control group and 167 for the video group (p< 0.05). The therapy costs averaged US$2,602.00 in the control and US$287.00 in the video (p< 0.0001). No complications were reported while using the video.

Discussion: Use of the music video as a supplement to the rehabilitation program in the early postoperative period following total knee replacement is recommended due to improved patient satisfaction, earlier return to activities, and improved 6 and 8 week knee scores. These are achieved at a substantial cost savings which benefits both patients and society.
