App to Preoperatively Measure Hamstring Tendon Length and Thickness in Patients Planned for Arthroscopic ACL Repair

Anterior cruciate ligament (ACL) reconstruction using hamstring tendon autograft requires adequate graft length and diameter for optimal surgical outcomes. Intraoperative measurement of graft size may lead to uncertainty and need for alternative graft options. This study aims to develop and validate a mobile application that predicts hamstring tendon length and diameter preoperatively using MRI-based and/or anthropometric parameters. Patients undergoing primary arthroscopic ACL reconstruction will be prospectively enrolled. Preoperative graft size predicted by the mobile application will be compared with actual intraoperative graft measurements. The study intends to evaluate the accuracy, correlation, and clinical utility of the application in predicting graft adequacy, thereby improving preoperative planning and reducing intraoperative uncertainty.
