Currently, functional outcome following total knee arthroplasty (TKA) is not fully restored, with the majority of TKA patients exhibiting lower functional outcome scores than their healthy counterparts [1]. A contributing factor to limited functional outcome may be the nature of the rehabilitation provided as there is still some controversy regarding the most appropriate methods for rehabilitation delivery [2]. Providing patients with visual feedback during rehabilitation has had a positive effect in other patient populations such as stroke survivors [3] and therefore may also improve the efficacy of orthopaedic rehabilitation. The aim of this study was to develop a visual feedback tool based on real time data from 3D motion capture for routine clinical use. Further aims included determining if provision of augmented feedback was acceptable to patients and whether it had a positive effect on functional outcome. Visual feedback using motion analysis was successfully delivered in a routine clinical environment and was widely acceptable to patients. Further, provision of visual feedback appeared to lead to improved knee range of motion in the sagittal plane in comparison to control patients. However, larger scale studies are required to confirm these positive effects.
