Rectus femoris tendinopathy Rectus femoris tendinitis / inflammation of the tendon of the rectus femoris (hip flexor) muscle
Introduction
Rectus femoris tendinopathy affects the tendon of an important thigh muscle. This causes pain along the front of the hip and thigh.
The rectus femoris is one of the four muscles that form the quadriceps muscle group. The rectus femoris runs from the hip to the knee. Its main functions are extending the knee and flexing the hip.

Description of the condition
The tendon along the upper portion of the rectus femoris is inflamed. This produces pain along the front of the hip. In more severe cases the tendon can tear partially or completely. An affected tendon causes pain when the muscle contracts or is stretched.
Cause and origin
The most important cause is overloading. This can develop gradually or acutely as a result of a rapid, brief physical effort.
Signs & symptoms
- Pain along the front of the hip and/or thigh.
- Pressing on the painful area makes the symptoms worse.
- Pain when elevating and/or extending the knee against resistance.
- Pain when stretching the quadriceps muscle.
- The front of the hip can feel stiff.
- The symptoms can occur during various activities that involve this muscle. Examples include running or playing football.
Diagnosis
The diagnosis rectus femoris tendinopathy is a clinical diagnosis. This means that the diagnosis can be made based on a consultation and physical examination, without the need for additional tests.
Particularly tests that involve exerting force over the tendon cause pain complaints.
Ultrasound can optionally be used to visualize calcification and assess the quality of the tendon tissue.
Treatment and recovery
The treatment involves training the rectus femoris muscle and tendon, along with the other surrounding muscles. Underloading of a body part often precedes overloading. The muscle is then not strong enough to handle the load. Proper muscle training is crucial to prevent this.
Both strength and stretching exercises can be prescribed for training. With a well-structured training regimen, muscle tissue becomes stronger, which significantly reduces the likelihood of overload. If there is any calcification, it may be treated with shockwave therapy.
