A groin strain is a partial or complete tear of the small fibers of the adductor muscles. The adductors are a group of muscles located on the inner side of the thigh. They start in the groin area and run down the inner thigh to attach to the inner side of the knee.

Groin strain is a common sports-related injury. Treatment depends on the severity of the strain.

A groin strain can be caused by:

  • Stretching the adductor muscles beyond the amount of tension they can withstand
  • Suddenly putting stress on the adductor muscles when they are not ready for stress
  • Overusing the adductor muscles over time
  • Getting a direct blow to the adductor muscles
