Morphological study and clinical significance of popliteofibular ligament
Objective To provide anatomic basis of the popliteofibular ligament (PFL) for clinical diagnosis and surgical treatment on its injury. Methods We performed this anatomical study on the PFL and its surrounding structures using 61 formalin-fixed knees, observing and measuring its length, width, thickness, and relationship with surrounding structures. Results The PFL consistently existed, it originated from popliteal tendon and inserted into styloid process of the fibular. It was fan-like shaped. PFL presented as ligament (89.5%) or fascia (11.5%). It was on an average (10.47±2.38)mm in posterior margin length, (6.24±1.71)mm in anterior margin length, (8.90±3.12)mm in width, 1.23±0.48mm in thickness. The angle between PFL and popliteal tendon was(120.2±15.2)°, the distance between anterior margin of PFL and posterior margin of lateral collateral ligament was (9.67±3.87) mm. Conclusions The PFL was one of posterolateral structure of knee, and it constantly existed but variable. So, with a good knowledge of its anatomic characteristics can be useful for the diagnosis and treatment for the PFL injuries.
