Background: Primary repair of anterior cruciate rupture is re-gaining attention with number of operations increasing. Comparing to ACL reconstruction with tendon graft, the benefits of primary repair may be outweighed by restoring the native anatomy of ACL and proprioception. The addition of an internal brace protects the repair during ACL healing and can increase the success rate. However, the outcome of internal brace are still controversial. Our study performed to evaluate the effectiveness of this method.
Methods: Inclusive criteria: age < 45, duration of trauma to surgery < 21 days. From 4/2022 - 4/2023, 48 patients with isolated anterior cruciate ligament rupture were performed arthroscopically anterior cruciate ligament repair with internal brace by a senior arthroscopist at Traumatology and Orthopedics Center of Tam Anh Hospital in Ho Chi Minh City. The patients were followed - up. Postoperative clinical results such as Tegner Lysholm, International Knee Documentation Committee (IKDC) before injury, at 2 weeks, 1 month, 3 months and 6 months after surgery were recorded. Knee stability tests by Dyneelax knee arthrometer were tested at 3 months and 6 months postoperatively. The patients were performed an MRI, Doppler ultrasound to investigate the vasculazation of the ligament at 6 months after the surgery.
Result: Median patient age at time of surgery was 24.8 years (range 16 - 33 years). The median time to surgery was 9.8 days (range 2 - 20 days). Median Lysholm score was 97.8 (range 95 - 100 ), the IKDC score was 91.2 (range 82 - 100); Tegner score was 5.6 (range 5 - 7). In terms of difference to the other side, Lachman test was 1.3mm (0 - 3mm); 93.75% had positive doppler signal in the ligament. Only 2 cases (4.2%) had knee instability and was re-operated with ACL reconstruction surgery.
Conclusion: At the final follow - up, the healed anterior cruciate ligament had an excellent functional outcome and low revision rate.
