The posterior cruciate (PCL) is composed of two bands that blend together. It attaches to the posterior intercondylar area and passes anterosuperiorly to insert into the lateral surface of the medial femoral condyle. The PCL is responsible for posterior translation of the tibia on the femur in open kinetic chain and anterior translation of the femur on the tibia in closed kinetic chain.
Evaluating the SI Joint can be challenging with very small amounts of movement and tests with variable statistical values.
The SI joint is stabilized by a network of ligaments and muscles. The normal sacroiliac joint has been shown to have approximately 2-4 mm of movement. So yes, the SIJ does move!
Assessing the value of "Special Tests" can be a clinical challenge.
Bone Stress Injuries (BSI) are the result of a bone’s inability to tolerate repeated mechanical loads.
