To explore the effect of the 6-minute walk test (6MWT) guided by non-invasive cardiac output on the rehabilitation of patients with knee osteoarthritis following artificial total knee arthroplasty. About 66 patients with knee osteoarthritis planned to undergo artificial total knee arthroplasty were included from March 2019 to October 2019, and randomly assigned to the intervention group or control group. Under the guidance of a clinical rehabilitation physician, orthopedic physician, and cardiologist, a home rehabilitation exercise program based on 6MWT and non-invasive cardiac output was formulated for patients with knee osteoarthritis. The participants of the intervention group conducted full rehabilitation training supervision and guidance through the WeChat platform to ensure their rehabilitation pieces of training were completed safely and effectively. As for the control group, patients were just given rehabilitation training manuals at the time of discharge and completed the training by themselves. At 6 months post-operatively, 6-minute walk distance (413.88 ± 44.61 vs. 375.00 ± 40.53 m, < 0.05), active metabolic equivalent (4.13 ± 0.29 vs. 3.88 ± 0.27, < 0.05), stroke volume after 6MWT (114.97 ± 12.05 vs. 98.38 ± 16.43 ml, < 0.05), and cardiac output (11.92 ± 1.68 vs. 9.79 ± 1.82 l/min, < 0.05) of the intervention group were significantly higher than those of the control group. The symptom evaluation scores of the intervention group were also better than those of the control group. The multidisciplinary post-operative rehabilitation exercise training program is beneficial to the recovery of lower limb function and the improvement of exercise capacity after knee replacement, and it also helps to improve the non-invasive hemodynamic indicators related to the cardiac function of the patient. http://www.chictr.org.cn/index.aspx.
探讨无创心输出量指导下的6分钟步行试验（6MWT）对人工全膝关节置换术后膝骨关节炎患者康复的影响。选取2019年3月至2019年10月计划行人工全膝关节置换术的66例膝骨关节炎患者，随机分为干预组和对照组。在临床康复医师、骨科医师和心脏科医师的指导下，为膝骨关节炎患者制定基于6MWT和无创心输出量的家庭康复锻炼计划。干预组参与者通过微信平台进行全程康复训练监督和指导，以确保其康复训练安全、有效地完成。对照组患者仅在出院时给予康复训练手册，自行完成训练。术后6个月，干预组的6分钟步行距离（413.88±44.61 vs. 375.00±40.53 m，P<0.05）、活动代谢当量（4.13±0.29 vs. 3.88±0.27，P<0.05）、6MWT后的每搏输出量（114.97±12.05 vs. 98.38±16.43 ml，P<0.05）和心输出量（11.92±1.68 vs. 9.79±1.82 l/min，P<0.05）均显著高于对照组。干预组的症状评估得分也优于对照组。多学科术后康复锻炼训练计划有利于膝关节置换术后下肢功能的恢复和运动能力的提高，也有助于改善患者与心功能相关的无创血流动力学指标。http://www.chictr.org.cn/index.aspx。
