Evaluation of the Correlation Between Bone Tunnel Projection Placement and Clinical Outcomes in Anterior Cruciate Ligament Reconstruction Surgery

Anterior cruciate ligament (ACL) rupture is a common and clinically significant injury, particularly among young, active, and athletic adults, and may lead to knee instability and functional impairment. The resulting instability can limit activities of daily living and reduce sports performance, often increasing the need for surgical treatment in physically active individuals. Therefore, ACL reconstruction is widely accepted as an effective treatment option in appropriately selected patients. In the assessment of patients undergoing ACL reconstruction, not only postoperative clinical success but also the degree of preoperative instability may be important. Determining the effect of preoperative instability severity and side-to-side difference on postoperative functional outcomes, clinical recovery, radiological findings, return to daily activities, and return to sports may provide a more comprehensive and objective evaluation of surgical success. Although several studies have investigated clinical outcomes after ACL reconstruction, prospective studies evaluating the impact of preoperative instability on postoperative outcomes together with clinical, functional, and radiological parameters remain limited, particularly in our country. This prospective study aims to investigate the relationship between preoperative knee instability and postoperative clinical, functional, and radiological outcomes in patients undergoing ACL reconstruction at our institution. The findings are expected to contribute to the existing literature and provide useful information for clinical practice.
