Objective To explore the effectiveness of arthroscopic All-inside single needle vertical suture technique in treatment of complete radial tear of the meniscus. Methods Between January 2019 and January 2022, 18 patients (18 knees) with complete radial tear of the meniscus were treated by using arthroscopic All-inside single needle vertical suture technique. Among them, there were 12 males and 6 females with an average age of 37.1 years (range, 16-50 years). The causes of radial meniscus tears included the sports injuries in 11 cases, sprains/falls in 4 cases, and traffic accident injuries in 3 cases. The interval between injury and operation was 3-25 days (mean, 11.7 days). All patients had knee joint pain. Knee joint tenderness and McMurray sign were both positive. MRI showed the 15 cases of lateral meniscus tear and 3 cases of medial meniscus tear; 15 cases of anterior cruciate ligament injury, 1 case of posterior cruciate ligament injury, and 15 cases of tibial plateau bone contusion. Six patients underwent isolated meniscus repair and 12 patients with cruciate ligament rupture underwent meniscus repair and simultaneous cruciate ligament reconstruction. The operation time and incidence of postoperative complications were recorded. At last follow-up, the meniscus healing was evaluated according to Barrett’s criteria and knee joint MRI, respectively. Lysholm score and International Knee Documentation Committee (IKDC) score were used to evaluate the functional recovery of the knee joint. Results The operation time was 19-28 minutes (mean, 23.3 minutes) in 6 patients with isolated meniscus repair and 38-52 minutes (mean, 45.8 minutes) in 12 patients with meniscus repair and simultaneous cruciate ligament reconstruction. All incisions healed by first intention. After operation, 1 patient developed the deep vein thrombosis of lower limb, the other patients had no complication. All patients were followed up 12-18 months (mean, 15.2 months). At last follow-up, 16 cases of meniscus reached clinical healing according to Barrett’s criteria, with a healing rate of 88.9%. MRI re-examination of the knee joint showed that 5 cases had complete healing of the meniscus, 11 cases had partial healing, and 2 cases did not heal. The total healing rate (complete healing and partial healing) was 88.9%. After operation, the Lysholm score and IKDC score of 18 patients increased compared to preoperative scores, and further improved with time. The differences between different time points were significant (P<0.05). Six patients with isolated meniscus repair had the same changes in the above scores, and the differences between the different time points were significant (P<0.05). Conclusion The arthroscopic All-inside single needle vertical suture technique can achieve good short-term effectiveness in the treatment of complete radial tears of the meniscus.
