説明

Histological evaluations were performed on 13 patients who underwent anterior cruciate ligament (ACL) reconstruction using rolled-iliotibial tract autografts. At the time of the second-look operations after more than 18 months of interval from the reconstructions, tissues were biopsied from the anterior central surface of the reconstructed-ACL in the knee position of 60° flexion. The crimp period (CPD) of each specimens showing structure-spescific features were measured under polarized light after staining with hematoxylin and eosin. The number of fibroblasts per 1mm2 was also counted. Magnetic resonance imaging (MRI) examinations were carried out on the reconstructed-ACLs performed with 0.5 Tesla whole body system (Philips, Gyroscan), and the intensity in the area of the biopsy was evaluated by T1-weighted images. The correlations between the CPD and number of fibroblasts, arthroscopic findings, and the intensity of magnetic resonance imaging (MRI) in the area of the biopsy were evaluated.<br>Correlation was found between the CPD and number of fibroblasts and between the CPD and arthroscopic findings, while no correlation was observed between the CPD and MRI intensity.
