A pathology that the sartorius can encounter is a lateral femoral cutaneous nerve entrapment (LFCN). A neuropathy condition called meralgia paresthetica (MP) creates burning, tingling, or numbness on the anterior thigh when standing or walking.
The sartorius contributes to this condition and and can have similar symptoms to MP. Some factors related to MP are obesity, pregnancy, repetitive muscle stretching, direct trauma, tight garments (e.g., jeans, military armor, police uniforms, seat belts), and more.
If sartorius TrPs are activated, a surprising sharp or tingling pain, not the usual deep aching pain associated with most TrPs. TrPs at the attachment area on the tibia are especially tender due to sustained tension to that region.
The sartorius, a biarticular muscle, so the compromise occurs at the attachments at ASIS and pes anserine.
In a standing position, with the leg extended and externally rotated, find the sartorius sandwiched between the vastus medialis and rectus femoris. Then use fingertips to cross-fiber massage down from the anterior to medial thigh.
The sartorius is typically injured when the leg and trunk are moving in opposite directions. It’s pegged as the honeymoon muscle because of the prime activity most likely done during a honeymoon: primarily abducting and laterally rotating the hip.
