Adductor longus is the most prominent of the adductors, visible as a cord from the pubic body to the thigh in lean individuals. Its proximal tendon is the most commonly injured muscle in groin strains in footballers.
| Origin | Body of the pubis — anterior surface, between the crest and the pubic symphysis |
|---|---|
| Insertion | Middle third of the linea aspera — medial lip |
| Nerve Supply | Anterior division of obturator nerve (L2, L3, L4) |
| Blood Supply | Medial circumflex femoral and perforating arteries |
| Actions | Adducts the thigh — the most powerful adductor; Flexes the hip from full extension; Assists medial rotation |

Adductor longus proximal tendon avulsion produces the characteristic MRI finding of pubic bone marrow oedema with tendon discontinuity. The "Athletic Pubalgia" (sports hernia) complex includes adductor longus origin pathology. Surgical repair of the proximal tendon is performed for complete avulsions in professional athletes.
Palpated as the cord running from the pubic body to the medial thigh during resisted hip adduction.
Complete adductor longus tendon avulsion from the pubic body in a footballer producing acute medial thigh pain and weakness of hip adduction, requiring surgical repair in elite athletes.
