Trial Outcomes & Findings for Comparison of Femoral Tunnel and Clinical Outcome Using Two Anterior Cruciate Ligament Reconstruction Techniques (NCT NCT02754674)

NCT ID: NCT02754674

Last Updated: 2019-12-20

Results Overview

For evaluation of graft vascularity, quantitative parameter of area under the curve (AUC) was measured from DCE-MRI by using an image-processing software (IntelliSpace Portal, version 5.0; Philips Healthcare). A musculoskeletal radiologist manually drew the ROIs for intra-articular portion of the ACL graft including synovial membrane at the proximal, middle and distal zones. The software automatically generated time to signal intensity curves and then calculated the quantitative parameter, area under the time to signal intensity curve values, which were acquired by integrating the area under the time to signal intensity curve. To normalize the AUC (nAUC), we divided the AUC of medial gastrocnemius muscle into that of the ACL graft.

SECONDARY outcome

Timeframe: 1yr after surgery

Graft continuity was graded as no tears, superficial tear (fibrillation or tear of superficial fibers), or substantial tear (rupture of 1 or more strands). Graft tension was graded as taut, mild lax, and lax by probing at knee flexion and extension. Synovial coverage of the grafts was graded as excellent (synovial coverage \> 80% around graft), fair (coverage \> 50%), or poor (coverage \< 50%) On the second-look arthroscopic examination, graft continuity, graft tension, graft synovialization, and the presence of cyclops lesions were assessed by a senior surgeon.
