Objective To observe and analyze the intervention effect of ultra-early graded rehabilitation training on muscle strength decline and knee joint movement disorder after ACL surgery. Methods 120 patients who underwent arthroscopic ACL reconstruction surgery in the hospital from January 2026 to April 2026 were selected and randomly divided by the random number table method. The control group (60 cases): routine care; the observation group (60 cases): ultra-early graded rehabilitation training. The muscle strength indicators, knee joint range of motion, knee joint function and complication rate of the two groups were compared. Results Compared with the control group, after intervention, the peak torque of the quadriceps femoris and hamstring muscles in the observation group was higher, and the difference was significant (P < 0.05); compared with the control group, the change in knee joint range of motion in the observation group after intervention was greater, and the knee joint function score was higher, and the difference was significant (P < 0.05); the complication rate of the observation group was lower, which was 5.00% (3/60) vs 18.33% (11/60), and the difference was significant (P < 0.05). Conclusion Implementing ultra-early graded rehabilitation training for patients after ACL reconstruction can improve the muscle strength of the quadriceps femoris and hamstring muscles, expand the range of knee joint flexion and extension, improve knee joint function, and reduce the incidence of complications. The intervention effect is good and worthy of promotion.
