The only 2-joint hip adductor; a weak adductor and knee flexor that the body can do without.
Detail
The gracilis is the only 2-joint muscle of all the adductor muscles and is also a knee flexor. It is a weak adductor, and under normal living one can live without it (it can be used as a surgical transplant). As a 2-joint muscle, the gracilis limits hip abduction (hip abduction ROM is 45 degrees, limited by the 2-joint gracilis muscle). The gracilis is also listed as a weak knee flexor (along with the sartorius).
Key facts
- Only 2-joint muscle among the hip adductors; also a knee flexor.
- Weak adductor; functionally expendable; usable as a transplant.
- The 2-joint gracilis limits hip abduction to 45°.
Connections
- Hip Adductors — group it belongs to.
- Hip Joint Range of Motion — limits hip abduction.
