초록

The anterior cruciate ligament (ACL) and the posterolateral structures are functionally important structures
that assist with the stability of the knee joint. Sport-related injuries to these structures and reconstructive surgery
are becoming more frequent. However, the anatomic characteristics and the relationship between these structures are
not well understood. We measured the morphological characteristics of the posterolateral structures of the knee and the
ACL, and we identified the anatomic relationship between the center of the femoral attachment area of the ACL and
other femoral structures. We dissected 34 cadaveric knees with no signs of previous surgery, knee abnormality, or disease.
The lateral collateral ligament (LCL) and the popliteus tendon (PLT) were present in all knees, although the
popliteofibular ligament (PFL) was not present in 20.6% of knees. The mean length of the LCL was 51.99 mm and
differed significantly between men and women (P⁄0.05). The mean length of the PLT was 21.59 mm, and the mean
length of the PFL was 18.49 mm. In 67.7% of knees, the PLT was attached to the inferior aspect of the femoral
attachment of the LCL, and the femoral attachment of the PLT was covered by the bundle of the LCL. The ACL was
distinguished into anteromedial (AM) and posterolateral (PL) bundles in all knees. The mean lengths of the AM and
PM bundles were 22.14 mm and 15.98 mm, respectively. The measured lengths in each bundle differed significantly
between men and women (P⁄0.05). The mean distance between the center of the femoral attachment area of the ACL
and the intercondylar line was 8.36 mm in the AM bundle, 15.98 mm in the PL bundle, and 10.96 mm in the entire
ACL. The mean distance between the center of the femoral attachment area of the ACL and the medial border of the
lateral condyle was 8.14 mm in the AM bundle, 7.36 mm in the PL bundle, and 8.45 mm in the entire ACL.
