The purpose of this randomized double-blind study was to investigate the effectiveness of the Videoinsight
One-hundred and ten patients treated with cemented total knee arthroplasty were randomly assigned to Group A or Group B, and both groups underwent the same rehabilitation programme. Group A (55 patients) received one art video selected according to Videoinsight
Eight patients were lost to follow-up, and 102 patients (Group A: 52 patients; Group B: 50 patients) were available at mean 3.0 ± 0.2 months follow-up. Age at surgery was 69.1 ± 13.0 years. The two groups were homogeneous regarding pre-operative demographic data and clinical outcomes. Significant improvements were observed in both groups compared to baseline and in Group A compared to Group B at final follow-up for functional and psychological scores except for SF-36. Respectively, Group A and Group B showed WOMAC 79.9 ± 13.0 and 69.7 ± 9.5 (p < 0.005), VAS 2.8 ± 1.6 and 4.0 ± 1.5, (p < 0.005), KSS 87.8 ± 9.6 and 78.3 ± 8.2 (p < 0.005), BDI 5.1 ± 4.8 and 9.4 ± 3.9 (p < 0.005), STAI 30.8 ± 7.9 and 34.8 ± 7.8 (p < 0.005), and TSK 24.4 ± 5.5 and 29.3 ± 4.8 (p < 0.005).
