[Treatment for posterior root tear of lateral meniscus through bone tunnel suture under arthroscopy].

OBJECTIVE

To evaluate clinical effects of posterior root tear of lateral meniscus through bone tunnel suture under arthroscopy.

METHODS

From January 2012 to December 2014, 23 patients with posterior root tear of lateral meniscus repaired through bone tunnel suture under arthroscopy, including 15 males and 8 females, aged from 19 to 48 years old with an average age of (25.0±4.7) years old; 10 knees on the left side and 13 knees on the right side. Complications were observed, Lysholm score before and after operation at 12 months were used to evaluate clinical results, and VAS score was applied to assess pain relief. MRI was used to check recovery outcomes of lateral meniscus injury.

RESULTS

All patients were followed up from 13 to 24 months with an average of (17.0±4.3) months. No injury of vessels, nerve and incision infection occurred. Motion of knee joint of 19 patients reached normal, 4 patients manifested limited activity of knee joint at12 months after operation. Postoperative Lysholm score 88.52±6.48 at 12 months was higher than that of before operation 46.12±7.35; Postoperative VAS score 0.8±0.7 at 12 months was lower than that of before operation 4.3±1.6.

CONCLUSIONS

Bone tunnel suture under arthroscopy for the treatment of posterior root tear of lateral meniscus could relieve pain, decrease postoperative complications and obtain good clinical efficacy.
