Effectiveness of Robot-Assisted Rehabilitation for Patients Following Total Hip Replacement: A Systematic Review of Randomized Controlled Trials Over the Last Decade

Purpose: This systematic review and meta-analysis aim to evaluate the clinical effectiveness of robot-assisted rehabilitation compared to conventional physical therapy for adult patients following primary Total Hip Replacement (THR). Despite the increasing use of robotic technologies, such as lower limb exoskeletons and gait-assistive robots, their standardized impact on postoperative recovery remains to be comprehensively synthesized. Methods: We will conduct a comprehensive literature search in major databases, including PubMed and Embase, using a predefined search string targeting Randomized Controlled Trials (RCTs) published between 2015 and 2026. The study population includes adults who underwent primary THR. The intervention focuses on robot-assisted training, while the control group receives conventional ground-based physical therapy or general exercise programs. Expected Outcomes: The primary outcomes will focus on gait ability (measured by 10MWT and TUG) and hip function (measured by HHS and WOMAC scores). Secondary outcomes will include lower extremity muscle strength, quality of life (EQ-5D), and pain levels (VAS). This study will provide evidence-based insights into the integration of robotic technology in orthopedic rehabilitation.
