전방십자인대 재건술의 조직학적 연구

Macroscopic and microscopie examination were conducted after endoscopic anterior cruciate ligament (ACL) reconstmction to ohserve a histological findings of reconstructed ACL in accordance with periods of follow-up, 2nd look arthroscopy and biopsy from the reconstructed ACL was performed from 12 cases out of 82 endoscopic ACL reconstructions using central 1/3 bone-patellar tendon-bone autografts, which were followed up for from 4 months to 2 years and 2 months after reconstruction. At 4 months afiter reconstruction, spindle or ovoid shaped fibroblast with hypercellularity, crimp patterns of collagen fiber, patallel arrangement of fibroblast to collagen fiber were noted. And the oel 'ty of fibroblast decreased in according to periods of follow up. At 12 months follow up, spindle or ovoid fibmblast, it's cellularity arrangement pattern and crimp pattern of collagen fiber were almost similar to those of normal ACL and continued unbl up to 2 years and 2 months after reconstruction.
