The Videoinsight® Method: improving early results following total knee arthroplasty

Purpose The purpose of this randomized double-blind study was to investigate the effectiveness of the Videoinsight ® psychological enhancing method in promoting early recovery during rehabilitation following total knee arthroplasty. Methods 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 ® concept. This art video promoting self-confidence and psychological support to the patient has been shown in the physical therapy department before any rehabilitation session, in the first 15 days after surgery and then three times a week for the next 4 weeks. Group B (55 patients) underwent the same rehabilitation protocol in the same setting, after TKA surgery, without the video support. Patients were evaluated pre-operatively and 3 months after surgery with Physical and Mental SF-36, State-Trait Anxiety Inventory (STAI), Beck Depression Inventory (BDI), Tampa Scale of Kinesiophobia (TSK), Knee Society Score (KSS), VAS, and WOMAC scores. Results 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
