Hip Strain
Hip Strain
Rectus femoris strain, referred to as hip flexor strain, is an injury commonly at the tendon that attaches to the patella or in the muscle itself. The injury is usually a partial tear but could be a full tear. The injury is caused by a forceful movement related to sprinting, jumping, or kicking and is common in sports like football or soccer. The rectus femoris is prone to injury since it crosses both the knee and the hip. Symptoms include a sudden sharp pain at the front of the hip or in the groin, swelling and bruising, and an inability to contract the rectus femoris with a full tear.
