DB: Two tunnels were created on the femoral side through an anteromedial portal. These tunnels were created manually. On the tibial side, the tunnels were created using a guide to ensure they matched the anatomic insertion site of the ACL at the tibia. The hamstring grafts for the procedure were then harvested from the same leg and doubled. The femoral side was fixed from the inside out, whereas the tibial side was fixed from the outside in. bioresorbable screws were used.

which group has more osteoarthritis? Kellgren Lawrence classification. Scale 0-4 (0=no OA)

which group has more positive pivot shift tests? Always compared to a "healthy" knee.

Anteroposterior translation. Always compared to a "healthy" knee. mm.

subjective evaluation form

Overall evaluation of the knee

which group has more graft failures? The number of graft failures was assessed by revision surgery.

Which group has more lack of knee extension or lack of knee flexion? Injured knee is always compared to a contralateral "healthy" knee. Measurements were performed with a goniometer. ROM included lack of passive extension (normal < 3°, nearly normal 3-5°, abnormal 6-10°, and severely abnormal > 10°) and lack of passive flexion (normal 0-5°, nearly normal 6-15°, abnormal 16-25°, and severely abnormal > 25°).
