The Tensor Fascia Lata is the tiny muscle that attaches to a huge fascia-like tendon called the Illiotibial Band (sometimes called the Illiotibial Tract). This band of tissue runs from the illium (the hip bone) to the distal lateral tibia (lower, outer knee), and covers the entire outer portion of the thigh.
Because it crosses both the hip and the knee, it is very capable of causing problems at both joints, although the pain is frequently (especially in runners) seen at the outer knee. And although ITB problems can mimic the leg pain seen in sciatica, never confuse the two.
As you can imagine, problems with the ITB and TFL are frequently related to other problems as well. I frequently see ITB issues in women (and a few men) who have a chronic PIRIFORMIS SYNDROME. This is because the TFL is in the vicinity of all sorts of muscles and tissues, including the hamstrings, quads, and piriformis. The beauty of treating a ITB / TFL Syndrome is that the model for treating all of the ELASTIC, COLLAGEN-BASED CONNECTIVE TISSUES is essentially the same (HERE).
