A Pilot Study of Anatomic Double-Bundle Anterior Cruciate Ligament Reconstruction With Ligament Remnant Tissue Preservation
Abstract
Purpose: The purpose of this pilot study is to clarify the preliminary results of an anatomic double-bundle ACL reconstruction procedure with ligament remnant tissues. Methods: Using the trans-tibial technique, 2 doubled semitendinosus tendons were grafted into 4 tunnels created at the center of each bundle attachment, penetrating the ACL remnant tissue. Forty-four patients (27 men and 17 women) with an isolated ACL injury underwent ACL reconstruction using this procedure. The mean age of subjects was 29 years (range: 17-58). Postoperative clinical evaluations were performed at 16.6 months on average (range: 12-23). Radiologic evaluations were also performed to evaluate the tunnel location in the femur and the tibia. Results: The average operation time was 86 minutes (range: 72-96) in the cases with ACL reconstruction only. Postoperatively, the mean anterior laxity was 0.7 mm. The postoperative pivot-shift test was negative in 81.8% of the patients, while there were no patients evaluated as ++. No patients showed any extension or flexion deficit. There were no patients evaluated as "nearly abnormal" or "abnormal" under the IKDC evaluation. The tunnel angles of the 4 tunnels were identical to those reported in the previous study. Conclusions: The minimal 1-year clinical results of anatomic double-bundle ACL reconstruction with ligament remnant tissue preservation were comparable to the previously reported results of the anatomic double-bundle reconstruction without remnant tissue preservation. Level of Evidence: Level IV, Prospective case series.
