Background: Anterior cruciate ligament (ACL) is crucial for knee joint stability, but total failure can impair proprioception. Rehabilitation involves unique regimens, virtual reality VR games being a helpful aid. Purpose: Examining how a Wii Fit rehabilitation program affects knee proprioception following ACL reconstruction. Methods: Thirty patients were assigned randomly to Study group (A), and control group (B). For eight weeks, the study group received the Wii Fit training protocol three times a week, lasting forty minutes each, with a conventional exercise program tailored to the control group. The knee joint's position sense was measured in both groups, before and after activities using a Biodex isokinetic dynamometer. Results: After treatment the joint position error JPE significantly improved for group A and group B. With significant decrease of JPE for the three angles of group A compared to group B (P<0.01).: Conclusion: The results revealed that Playing weight shifting VR games on the Wii Fit for eight weeks, with a consistent exercise rehabilitation program, can significantly improve knee joint position sense.
