Effect of Remote Control Augmented Reality Multimedia Technology for Postoperative Rehabilitation of Knee Joint Injury

Abstract

This study was aimed at exploring the application value of augmented reality (AR) in postoperative rehabilitation training for patients with knee joint injury. 40 patients who underwent knee joint injury surgery were selected as the research objects, and the patients were randomly divided into two groups: an experimental group (20 cases) and a control group (20 cases). Patients in the experimental group were treated with AR-based rehabilitation methods, while those in the control group were treated with traditional rehabilitation methods. Afterwards, the two groups of patients were compared with various indicators such as pain value, swelling, structural and functional recovery, time to complete weight bearing, time to return to work, and X-ray examination results. The main evaluation tools used were Hospital for Special Surgery (HSS) score and Visual Analogue Scale (VAS) score. The results showed that after six weeks, the HSS score of the control group was 82.88 ± 3.07 , and the HSS score of the experimental group was 85.46 ± 3.21 . The difference between the two groups was statistically significant ( P < 0.05 ). After three months, the HSS score of the control group was 89.96 ± 3.76 , and that of the experimental group was 93.21 ± 4.33 . The difference between the two groups was statistically significant ( P < 0.05 ). There was a significant difference in pain scores between the two groups at 7 days ( 3.81 ± 0.48 vs. 5.06 ± 0.66 ) and 14 days ( 2.03 ± 0.45 vs. 3.61 ± 0.63 ) after surgery, with statistical significances ( P < 0.05 ). There were statistically significant differences between the two groups in terms of time to complete weight bearing ( 7 ± 0.87 weeks vs. 8.82 ± 0.88 weeks) and time to return to work ( 8.69 ± 0.94 vs. 9.93 ± 0.88 weeks) ( P < 0.05 ). One month after surgery, the X-ray examination results of both groups showed recovery. The AR-based rehabilitation training system showed a good application effect and prospect in the postoperative structural and functional recovery of patients with knee joint injury.

Effectiveness of Virtual Reality on Postoperative Pain, Disability and Range of Movement after Knee Replacement: A Systematic Review and Meta-Analysis

“…All five randomized controlled trials (RCTs) included in the meta-analysis were published in English. These studies were conducted in various countries: China [ 19 , 23 ], Italy [ 20 ], the USA [ 21 ], and Israel [ 22 ]. The publication dates ranged from 2018 to 2022.…”

A Systematic Review and Meta-Analysis of the Effects of Rehabilitation Using Digital Healthcare on Musculoskeletal Pain and Quality of Life

“…Most of the included MSD studies (n = 22) were conducted on patients with affected knee or hip joints. 29 , 30 , 32 , 34–38 , 40 , 43 , 46 , 49–51 , 54 , 55 , 60 , 67 , 71 , 72 , 78 , 80 Among these studies, 1 was conducted on patients undergoing hip arthroplasty, 55 and 9 on patients undergoing knee arthroplasty. 35–38 , 40 , 43 , 54 , 71 , 80 In addition to studies on carpal tunnel release 31 and shoulder MSD, 33 , 41 studies on patients with ankle sprains, 42 fibromyalgia, 74 distal radius fractures, 66 and lumbar discs 39 were included.…”

“…In five studies evaluating the effectiveness of rehabilitation from hospitalization, 37 , 38 , 43 , 67 , 71 the follow-up period ranges from less than 1 week to 4 months. In the other studies, it ranged from 2 weeks to 24 months to evaluate the effect of DHC intervention in an outpatient setting.…”

“… 30 , 44 , 46 , 51 , 64 , 75 Six studies were marked as having a high risk of attrition bias, 45 , 46 , 70 , 72 , 78 , 79 and the occurrence of this bias remained uncertain in some of the studies. 41 , 44 , 62 , 65 , 67 , 68 , 82 Furthermore, some studies confirmed having unreported results; therefore, the risk of reporting bias was evaluated as high. 34 , 43 , 52 , 69 , 76 The possibility of another bias was evaluated using limitations and the funding of each study, and eight studies were assessed as having a high RoB because the author was an intervention developer 32 or received benefits related directly or indirectly to work.…”

Integration of Square Fiducial Markers in Patient-Specific Instrumentation and Their Applicability in Knee Surgery

“…The authors underlined the need for future research to demonstrate the advantages of these technologies compared to face-to-face orthopaedic rehabilitation. Lingfeng Li [ 61 ] randomly divided 88 patients who underwent knee joint injury surgery into an experimental group (treated with AR-based rehabilitation after the surgery) and a control group (treated with traditional rehabilitation). Li stated that, compared with conventional methods, the rehabilitation training method based on AR showed substantial advantages in alleviating postoperative pain and helping structural and functional recovery [ 61 ].…”
