The curative efficacy of arthroscopic therapy in treating anterior cruciate ligament rupture with secondary osteoarthritis

To compare and analyze the clinical effects of arthroscopic therapy and drug therapy in treating anterior cruciate ligament (ACL) rupture with secondary osteoarthritis (OA).

A total of 68 patients that were diagnosed as ACL rupture with secondary OA in our hospital from February 2014 to February 2015 were enrolled in our study. All of the patients were randomly divided into control group (n = 30) and observation group (n = 38) according to the order of admission. The patients in the control group were given analgesic, anti-inflammatory drugs + functional rehabilitation training whereas the patients in the observation group were given ACL reconstruction + OA debridement and functional rehabilitation training under arthroscopy.

The success rate of the observation group was 92.1%. After 3-month follow-up, the clinical total effective rate of the observation group was significantly higher than that of the control group, the prevalence of complications in the observation group was significantly lower than in the control group, and differences were statistically significant (p < 0.05). Lysholm scale scoring of observation group was significantly higher than of the control group, modified McGill pain scale score was significantly lower than that of the control group, and differences were statistically significant (p < 0.05). Quadriceps muscle peak torque, average power, and the optimal single work at 60°/s, 120°/s, and 180°/s were significantly higher than those of the control group, and differences were statistically significant (p < 0.05).

Arthroscopic operative therapy was safe and effective for the treatment of ACL with secondary OA. Compared with drug therapy, it can significantly improve the movement function of the knee joint, so it was worthy of clinical application.
