Hip Flexor
If you suffer from a hip flexor injury, please Schedule an appointment with one of our orthopedic specialists as soon as possible.
What is a Hip Flexor Strain?
A hip flexor strain involves stretching or tearing one or more muscles or tendons within the hip flexor group, which includes the iliopsoas, rectus femoris, sartorius, and tensor fasciae latae. These muscles connect the pelvis and upper leg and allow the hip to lift the knee, bend the hip, and support walking, running, kicking, and other lower-body movements. Damage can range from mild overstretching to a complete muscle or tendon tear.
Specialists classify hip flexor strains into three grades based on the extent of tissue damage. Grade 1 strains involve minor muscle fiber stretching with minimal loss of strength or function. Grade 2 strains involve a partial tear that reduces strength and limits movement. Grade 3 strains involve a complete muscle or tendon tear that causes significant loss of function and often requires more extensive treatment and rehabilitation.
Muscle strains vs. pulled muscles
There’s no difference between a strained muscled and a pulled muscle. However, people use the terms interchangeably. The same is true for a strained muscle and a torn muscle. They’re the same injury with the same symptoms and treatments.
