Rectus Femoris Trigger Point Patterns and Pain
Rectus Femoris is one of the quadriceps muscles and is located superficially on the central anterior aspect of the upper leg. It helps to extend the leg at the knee and to flex the thigh at the hip. It’s the only quadriceps muscle to cross both the hip and knee joints.
Its origin attachment is on the anterior inferior iliac spine (AIIS), and along with the other quadriceps muscles, it inserts on the tibial tuberosity via the common patellar tendon.
There is a primary trigger point in the rectus femoris located just distally to its origin at the AIIS. It typically refers pain deep under the kneecap or to the front of the knee. A secondary trigger point in rectus femoris may occur just proximal to the knee and refer only local pain.
As with the other quadriceps muscles, rectus femoris may become irritated from any overuse of the knee, sitting for long periods, and may also become painful as a result of overdoing exercises like knee bends. In addition, running and sports like skiing and soccer may irritate it. Pain may be exacerbated by walking downstairs or downhill.
Unresolved trigger points in the hamstrings on the posterior upper leg may contribute to tightness and pain in rectus femoris, and anterior tilt of the pelvis can cause rectus femoris pain as a result of its attachment at the hip. It is important to stretch both the hamstrings and quadriceps muscles.
You can help guide your massage session to effectively release trigger points and pain in rectus femoris as well as the other quadriceps muscles. Let your LMT know when you’re feeling a tender point and when it feels like it’s letting go.
