Abstract:
Objective To design an arthroscopic universal aiming device for cruciate ligament repairing and evaluate its clinical efficacy. Methods The aiming device was designed on the principle of “a line crossing any point on a spherical surface and perpendicular to it must cross the sphere center”, which enables the surgeon to locate the ligamentous attachment of cruciate ligament precisely for reconstruction. Twelve cases of PCL injuries have been treated with this method. Results The average follow up period was 12.1 months (5-19 months). According to Lysholm scoring system, the average score was improved from 59.2 points to 92.7 points, increased by 33.5 points. Lachman test turned negative in all patients, the average range of motion was 120?. Conclusion The instrument was reasonably designed for easy handling and precise orientation. It is particularly preferable to locate the tibial attachment of cruciate ligament for endoscopic reconstruction on the posteromedial approach.
