An adductor magnus injury involves damage (strain, tear, or contusion) to one of the large muscles on the inner thigh that helps bring the leg toward the body’s midline and assists in hip extension.
Here’s a breakdown of what you should know 👇
⸻
🧠 Anatomy Overview
• Adductor magnus is the largest of the adductor group (along with adductor longus, brevis, gracilis, and pectineus).
• It has two parts:
• Adductor part: attaches to the femur and assists in hip adduction and flexion.
• Hamstring part: attaches to the ischial tuberosity and helps in hip extension.

⚠️ Common Causes of Injury
• Sudden change of direction while running or kicking (e.g., soccer, hockey).
• Overstretching during sports or exercise.
• Poor warm-up or fatigue leading to muscle overload.
• Direct trauma (less common).
⸻
🔍 Symptoms
• Sharp or aching pain in the inner thigh or groin area.
• Pain when adducting (squeezing legs together) or extending the hip.
• Swelling or bruising (especially with a tear).
• Weakness or stiffness in the groin.
• Pain when walking, sprinting, or climbing stairs.
⸻
🧪 Diagnosis
• Physical exam: tenderness, pain on resisted adduction or stretching.
• Imaging:
• Ultrasound or MRI if a tear or hematoma is suspected.
