OBJECTIVE: To investigate the short-term effectiveness of transtibial pull-out technique combined with side-to-side suture technique in treatment of complete radial tear of lateral meniscus body.
METHODS: Between May 2020 and August 2023, 15 patients with complete radial tear of lateral meniscus body were repaired by arthroscopic transtibial pull-out technique combined with side-to-side suture technique. There were 11 males and 4 females, with an average age of 25.2 years (range, 15-43 years). Twelve cases were acute injuries and 3 were chronic injuries. All patients had tenderness in the lateral compartment of the knee. No abnormal alignment was observed on the X-ray films of the knee. MRI showed the complete radial tear of lateral meniscus body without associated injuries such as anterior cruciate ligament or cartilage. Preoperative Lysholm score was 44.5±6.4, International Knee Documentation Committee (IKDC) subjective score was 40.2±8.4, Tegner score was 1.3±1.1, and visual analogue scale (VAS) score for pain was 5.1±1.1. The operation time, incision healing, and complications such as vascular/nerve injury were recorded. During follow-up, the range of motion of the knee and tenderness in the lateral compartment of the knee were observed. The knee function and pain were evaluated using Lysholm score, Tegner score, IKDC subjective score, and VAS score. X-ray films and MRI of the knee were reexamined to assess knee degeneration.
RESULTS: The operation time was 60-145 minutes (mean, 89.6 minutes). All incisions healed by first intention, and no complication such as vascular/nerve injury occurred. All patients were followed up 17-56 months (mean, 38.4 months). All patients had no knee extension limitation and 3 cases had tenderness in the lateral compartment of the knee. At last follow-up, the Lysholm score, IKDC subjective score, Tegner score, and VAS score for pain were 85.3±7.8, 82.1±15.7, 4.7±1.2, and 1.5±1.0, respectively, which were superior to those before operation ( P<0.05). Imaging reexamination showed that the meniscus was reset at 1 day after operation, and there was no sign of knee degeneration at last follow-up.
CONCLUSION: Transtibial pull-out technique combined with side-to-side suture technique can effectively treat the complete radial tear of lateral meniscus body and obtain good short-term effectiveness.
