Results of Anterior Cruciate Ligament Reconstruction Using the All-Inside Technique at Pho Noi Hospital: A Retrospective Study

Objectives: To evaluate clinical and functional outcomes of anatomic anterior cruciate ligament (ACL) reconstruction using the all-inside technique. Methods: A retrospective study on 30 patients who underwent primary anatomic ACL reconstruction using the all-inside technique from January 2019 to January 2022 at Pho Noi Hospital, Hung Yen. The Lysholm score and International Knee Documentation Committee (IKDC) score were used to evaluate outcomes before surgery, at 6 months, and ≥ 12 months postoperatively. Results: Among 30 patients who underwent all-inside ACL reconstruction, the mean follow-up time was 26.5 months (13 - 50 months), the mean age was 32.43 ± 10.6, and the mean duration between the injury and surgery was 9.4 months. The mean graft diameter was 7.8 ± 0.5mm (6.5 - 9mm), the mean femoral tunnel length was 28.8 ± 1.7mm (25 - 35mm), and the mean tibial tunnel length was 30.5 ± 2.1mm (30 - 35mm). Functional outcomes: Preoperatively, the IKDC score was 55.2 ± 0.5, and the Lysholm score was 61.1 ± 4.5. At 6 months postoperatively, symptoms improved; at over 12 months postoperatively, the IKDC score was 91.5 ± 2.5. The rate of normal and nearly normal grades was 96.7% and the Lysholm score was 94.1 ± 2.5. The rate of excellent and good grades was 100%. Conclusion: The ACL reconstruction using the all-inside technique provides good functional outcomes and anteroposterior knee stability at short-term follow-up.
