Adductor Group: Pain Pattern and Treatment
The adductor longus and brevis run from the pubic bone down the inner thigh and pull the leg toward the midline. Their documented pattern works as one unit: a concentration of pain deep in the groin, spreading down the front-inner thigh and reaching the inner knee. This is the classic groin-strain territory, and an overlooked source of inner knee pain.
Attachments and action
Origin: The body and inferior ramus of the pubis.
Insertion: The linea aspera along the middle third of the femur.
Action: Adduction of the hip, drawing the thigh toward the midline, with assistance to hip flexion.
Where the pain is felt: Deep in the groin at the top of the inner thigh, spreading down the front-inner thigh, and at the inner knee.
Common causes: Side-to-side sports like soccer, hockey, and tennis, horseback riding, sudden slips with the legs apart, hill sprinting, an unaccustomed stretching session.
Patients say: “A groin pull that never fully heals.” Inner-thigh tightness on sprints. An inner knee that aches after skating.
When to get evaluated: Groin pain with a bulge that changes on coughing gets assessed for hernia, and groin pain that grinds on hip rotation gets imaging for joint disease, before needling.
How this muscle is examined and treated
Examination tests resisted adduction and hip range, screens the hip joint and hernia points, and maps the adductor longus and brevis near the pubic attachment for the points that reproduce the familiar groin and inner-thigh pain. Needling addresses the two muscles directly. Assessment and treatment happen in the same visit.
