[Arthroscopic pullout suture repair of posterior root tear of the medial meniscus via the double tibial tunnels].

Objective: To evaluate the surgical technique and clinical effect of arthroscopic pullout suture repair of posterior root tear of the medial meniscus via the double tibial tunnels.

Methods: From May 2014 to May 2017, 22 patients with posterior root tear of medial meniscus were treated by pullout suture repair via the double tibial tunnels, including 8 males and 14 females, aged 34 to 53 years old, with a mean of averaged(45.7±4.7) years old. The patients were followed up for 12 to 24 months, with a mean of (16.4±5.2) months.

Results: The Lysholm score of knee joint before operation was 61.8±4.3, IKDC score before operation was 59.9±2.9, Lysholm score at the latest follow-up was 89.1±3.0, and IKDC score was 89.0±2.5. The difference was statistically significant.

Conclusions: Arthroscopic pullout suture repair via the double tibial tunnelsis an effective treatment for symptomatic posterior root tear of medial meniscus, and it can significantly improve the knee functional outcome.
