PURPOSE Dynamic intraligamentary stabilization (DIS) is recognized as a ligament preserving technique for the treatment of acute anterior cruciate ligament (ACL) injuries. The aim of this study was to assess the integrity and morphology of the recovered ACL after DIS repair. METHODS The cohort comprised 47 patients with an acute proximal ACL rupture undergoing DIS repair. All patients underwent diagnostic arthroscopy after a minimum postoperative interval of 6 months for semi-quantitative evaluation of ACL integrity, function and scar tissue formation. Tegner, Lysholm and International Knee Documentation Committee (IKDC) scores as well as objective anteroposterior (ap) translation were assessed at 6 weeks, 3-, 6- and 12 months postoperatively. RESULTS Full restoration of the ACL volume was affirmed in 30 (63.8%) patients and two-third restoration in 13 (27.7%). Hypertrophic scar formation was observed in 23 (48.9%) patients. Forty-four patients (93.6%) demonstrated sufficient ACL tensioning intraoperatively ...
