Level IV, Case series; therapeutic study.

Objective: To investigate the effect of percutaneous acupoint electrical stimulation combined with early lower limb massage on knee rehabilitation after reconstruction of anterior cruciate ligament injury. Methods: 120 cases of patients admitted to our hospital from January 2019 to December 2022 were selected as the study subjects, and all patients were divided into observation group and control group, with 60 patients in each group. The patients in the control group took routine postoperative rehabilitation treatment. The observation group added percutaneous acupoint electrical stimulation combined with early lower limb massage on the basis of the pain and swelling before and for 6 months in the two groups, location perception and motion perception and knee function in the two groups. Results: The swelling value and visual analog scale (VAS) scores in the two treatment groups were significantly decreased, and the observation group was lower than the control group (P <0.05); the knee and 45 degrees, knee extension and knee motion were lower than the control group (P <0.05); the knee subjective (IKDC) score and knee function (Lysholm) scores were significantly lower, and the observation group was lower than the control group (P <0.05). Conclusion: Percutaneous acupoint electrical stimulation combined with early lower limb massage can reduce the long-term pain and swelling after knee anterior cruciate ligament injury reconstruction, improve the patient's knee position and motion perception, and further improve the knee function and motor function.
