Educational content only — not medical advice.

Anatomy

The longest and most superficial medial thigh muscle — a slim strap from the pubis to the medial tibial surface via the pes anserinus; the only adductor crossing two joints.

Origin & insertion

Body and inferior ramus of the pubis.

Action

Adducts the hip, flexes the knee and medially rotates it — the dual hip-knee adductor of cross-legged sitting.

Innervation

Obturator nerve — anterior branch (L2–L3).

Clinical notes

Its tendon is the standard ACL-reconstruction graft and latissimus repair; easily harvested without functional loss — the classic "donor muscle".
