Abstract Objective To investigate the effect of isokinetic strength training of thigh muscles on knee joint function and posture control after anterior cruciate ligament (ACL) reconstruction. Methods Eighty-six patients undergoing ACL reconstruction admitted to the First People’s Hospital of Lianyungang from March 2017 to February 2020 were selected as the research objects, and they were divided into two groups according to the random number table method, with 43 cases in each group. The control group was given conventional rehabilitation training after the operation, and the study group was given isokinetic training of the thigh muscles after the operation on the basis of the control group. Follow-up for one year, three months after operation (T0), six months after operation (T1), and 12 months after operation (T2), the peak extension torque (PT), knee function, and posture control ability of the two groups were compared. Results There were statistically significant differences betwween the two groups in knee extension PT, Lysholm score, eye-closed foam plane gravity swing speed, time point comparison and interaction between the two groups (P ＜ 0.05). At T1, knee extension PT, Lysholm score, and eye-closed foam plane gravity swing speed in the two groups were higher than T0, and the differences were statistically significant (P ＜ 0.05), at T2, the knee extension PT, Lysholm score, and eye-closed foam plane gravity swing speed between the two groups were higher than those at T0 and T1, and the differences were statistically significant (P ＜ 0.05). At T0, there were no significant differences between the two groups in terms of knee extension PT, Lysholm score, and eye-closed foam plane gravity swing speed (P ＞ 0.05), at T1 and T2, the knee extension PT, Lysholm score, and eye-closed foam plane gravity swing speed in the study group were higher than those in the control group, at the some time point, and the differences were statistically significant (P ＜ 0.05). Conclusion Isokinetic training of the thigh muscles can improve the knee joint function and posture control ability of patients after ACL reconstruction.
