Background: Total knee replacement (TKR) is a common intervention for advanced knee joint disease, but postoperative motor function recovery can be variable. Robot-assisted training (RAT) has emerged as a promising modality to enhance rehabilitation outcomes.
Objective: To systematically evaluate the effectiveness of robot-assisted training in improving motor function outcomes after TKR.
Methods: A systematic review was conducted following PRISMA 2020 guidelines. Electronic databases including PubMed, Scopus, Web of Science, and Embase were searched for studies published between 2013 and 2025. Eligible studies included RCTs, cohort studies, and systematic reviews reporting motor outcomes following RAT in adult TKR patients.
Results: Fifteen studies met inclusion criteria. RAT demonstrated statistically significant improvements in range of motion (15–28%), quadriceps strength (up to 25%), gait performance (TUG and 6MWT), and pain reduction (VAS decrease by 2.4–3.2 points) compared to conventional therapy. No adverse events were attributed to robotic interventions.
Conclusion: RAT enhances motor function recovery post-TKR and may serve as a safe and effective adjunct to standard rehabilitation protocols. Its integration into clinical pathways warrants further study for long-term outcomes and cost- effectiveness.
