Abstract：【Objective】To explore the effects of Pro-kin balance system combined with blood flow restriction(BFR) training on knee proprioception, knee joint function, and motor coordination in patients undergoing anterior cruciate ligament reconstruction surgery. 【Methods】A total of 82 patients who underwent anterior cruciate ligament reconstruction surgery in our hospital from January 2020 to January 2023 were selected and randomly divided into an observation group and a control group using a random number table method, with 41 patients in each group. The control group received postoperative BFR training, while the observation group received postoperative Pro-kin balance system training in addition to the control group. After 3 months of treatment, two groups were compared in terms of quadriceps cross-sectional area, flexor extensor ratio(H/Q), relative peak torque(PT/BW), knee proprioceptive index, knee joint function score, and motor coordination. 【Results】The difference in cross-sectional area of the quadriceps femoris muscle on the affected side between 7 days and 3 months after surgery in the observation group was smaller than that in the control group(P<0.05); The difference in H/Q, PT/BW, 30° position deviation, 60° position deviation, collaborative contraction rate, and average energy frequency between the observation group at 7 days and 3 months after surgery was greater than that of the control group(P<0.05). The difference in knee joint function scores between the two groups at 1 month and 3 months after surgery was significantly higher than that at 1 week after surgery, with statistical significance(P<0.05). In addition, the knee joint function scores in the observation group at 1 month and 3 months after surgery were significantly higher than those in the control group, with statistical significance(P<0.05). The difference in collaborative contraction rate and average energy frequency between the observation group and the control group at 7 days and 3 months after surgery were all statistically significant(P<0.05). 【Conclusion】The combination of Pro-kin balance system and BFR training can inhibit quadriceps atrophy, promote knee joint function recovery, and is worthy of clinical promotion and application.
