Comparison of Remnant Preserving Versus Remnant Resecting Anterior Cruciate Ligament Reconstruction

The study design is a double-blind randomized controlled trial. Randomly, twenty patients planed to undergo anterior cruciate ligament reconstruction using autograft by remnant preserving and other twenty patients undergo anterior cruciate ligament reconstruction using autograft by resecting anterior cruciate ligament. The clinical outcome is comparative preoperative, postoperative 6weeks, 3months, 6months and 1years. And clinical score consists of Visual Analog Score, lachman test, anterior laxity, Lysholm knee score, international knee documentation committee score. Femoral and tibial tunnel location will be analyzed by three-dimensional computed tomography using Bernard quadrant method after surgery. The present study aimed to determine and compare (1) the accuracy of tibia and femoral tunnel location and (2) postoperative functional outcome after anterior cruciate ligament reconstruction between remnant preserving group versus remnant resecting group.
