Observational study improved knee flexion in patients with anterior cruciate ligament reconstruction, suggesting enhanced rehabilitation outcomes.

This research investigates the feasibility and efficacy of a single tunnel double-bundle approach for ACL reconstruction.
Prospective enrollment of 35 patients undergoing ACL reconstruction
Utilization of a unique rectangular tunnel dilator for footprint optimization
Soft tissue hamstring grafts used for reconstruction
Graft passage via graft squeezing method with fixation techniques on femoral and tibial sides
Outcomes assessed at 3 years using knee range of motion, Lysholm score, IKDC score, Lachman test, and pivot-shift test
Significant increase in knee flexion from an average 106 degrees preoperatively to 134 degrees at follow-up
Lysholm score improved from 52.46±8.13 to 92.79±1.00
IKDC score improved from 34.43±4.13 to 86.43±0.61
Positive outcomes across all evaluated parameters despite one complication (cyclops lesion)
