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

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.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.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.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.
