Application of virtual reality technology in postoperative rehabilitation following total knee arthroplasty: A scoping review

Abstract

Background

With the advent of an ageing era, the number of elderly patients undergoing knee joint replacement is increasing. Postoperative long-term standardized functional exercise is a focal point and difficulty in the recovery of joint function for patients after knee replacement. Virtual reality (VR) is increasingly considered a potentially effective option that can provide patients with a relaxed and enjoyable exercise method.

Objective

The primary objective of the scoping review to systematically evaluates the impact of virtual reality (VR) technology the movement and functional recovery, psychological state, pain levels, and quality of life of patients after total knee arthroplasty (TKA). It summarises and synthesises VR's effects and feasibility in TKA rehabilitation training, offering a scientific basis and reference for the professional advancement of orthopaedic practice nurses and future research in this domain.

Methods

We employed the Joanna Briggs Institute's scoping review guidelines as our methodological framework. The literature search spanned from January 2018 to December 31, 2023, encompassing databases such as PubMed, Web of Science, The Cochrane Library, Embase, CNKI, Wanfang, CQVIP, and the China Biomedical Literature Database.

Results

An initial search yielded 2708 articles, with 17 studies meeting the inclusion criteria after stringent screening. The findings indicate that VR equipment primarily comprises VR goggles, handheld controllers, and sensor technology. Interventions typically occurred 3 to 5 times weekly, lasting 20–30 min per session. The principal assessment metrics included pain levels, psychological state, joint function, and quality of life.

Conclusion

VR technology proves feasible in the rehabilitation of TKA patients, effectively alleviating pain, enhancing psychological states, and improving joint function and quality of life. However, discrepancies exist regarding VR's effect on bolstering lower limb muscle strength. Future research should focus on evidence-based medical practices, optimising VR intervention strategies, developing customised plans tailored to individual patient differences, and potentially extending intervention durations to amplify VR technology's application effects in TKA patient rehabilitation.
