SPORTS MECHANICS REHABILITATION EFFECTS ON KNEE AND MUSCLE

ABSTRACT Introduction: The knee joint is a complex and important joint in the human body. It plays an active role in maintaining posture balance of the human body in sports, allowing one to bear a larger load and complete various complex technical movements. Objective: To investigate the stability and influence of kinemechanics in knee joint rehabilitation training. Methods: A total of 80 patients with anterior cruciate ligament injury who received treatment in Henan Provincial People's Hospital were selected and divided into control group and observation group according to the random number table method, with 40 cases in each group. Results: Six months after surgery, the peak torque (PT), peak torque to body weight ratio (PT/BWT), total work (TWT), Lysholm score and Tegner score, and knee circumference of the two groups were significantly improved compared with those before surgery (P <0.01). The degree of improvement was greater in the observation group:compared with the control group, the difference was highly statistically significant (P<0.01). Conclusions: Professional exercise rehabilitation has a definite effect on patients after anterior cruciate ligament reconstruction. It can significantly improve the muscle strength of quadriceps and hamstring, improve the function of knee joint and promote its recovery. Level of evidence II; Therapeutic studies - investigation of treatment results.
