- Discussion:
- includes posterior 1/3 of lateral supporting structures;
- it includes
LCL,
arcuate ligament, & exension of
popliteus;
- posterior 1/3 of the lateral ligamentous complex is reinforced by biceps, popliteus, & lateral head of
gastrocnemius;
-
LCL:
- extracapsular fibular colateral ligament originates from lateral epicondyle and attaches to the fibular head;
- in approx 15% of pts short
LCL is demarcated by presence of fabella confluent with the posterior aspect of
LCL;
-
arcuate ligament:
- originates on posterolateral aspect of femur inserts distally onto posterolateral aspect of tibia & is reinforced by the biceps tendon;
Limits of movement in the human knee. Effect of sectioning the posterior cruciate ligament and posterolateral structures.
Knee dysfunction secondary to dislocation of the fabella.
The incidence of fabellae in osteoarthrosis of the knee.
