Patellofemoral Pain Syndrome vs. Patellar Tendinitis

Patellofemoral Pain Syndrome vs. Patellar Tendinitis

Q Angle

Anterior – or front – knee pain is a common symptom that we see at Kintec. Today, we are going to break down the difference between symptoms of patellofemoral pain syndrome vs. patellar tendinitis, which include anterior knee pain.

From highly competitive athletes to someone who stands or walks all day at work, pain at the front of the knee is common, and most importantly – very treatable.

It is helpful to be able to distinguish where the source of the pain is so that it can be treated appropriately.

Different pain sources indicate different conditions and require different treatments and braces.


What is Patellofemoral Pain Syndrome?

One of the most common conditions that are characterized by anterior knee pain is patellofemoral pain syndrome (PFPS). PFPS occurs when the knee cap does not stay in the patellar groove, and can move off to the side. The patella will typically move to the lateral side, or outside of the leg.

PFPS has many factors that contribute to its development, including overpronation of the foot, an excessive Q angle, anatomical patella shape, and muscular imbalance.

It can be positively impacted by several treatments:

  • Custom made orthotics to improve alignment and reduce over-pronation
  • Physiotherapy to strengthen weak muscles that are unable to keep the patella in its place
  • A brace to provide support for the patella during activity

donjoy-tru-pullA patellofemoral brace is characterized by a support or buttress surrounding the kneecap. The idea is to prevent the patella from moving to the lateral side of the knee.

The buttress can be a round, ‘donut’ shape, or a horseshoe (or ‘U’) shape, or a ‘C’ shape, hugging the outside of the kneecap, as seen here on the Donjoy Tru-Pull Lite.

The brace can be open/closed over the kneecap.

NOTE: There is one exception to this, and that is if you have been diagnosed with chondromalacia patella or patellar arthritis, in which pressure on the kneecap itself is discouraged.

What is Patellar Tendinitis?

Patellar tendinitis is quite different than PFPS and needs to be treated by health care professionals as such.

It is usually characterized by acute pain either at the bottom edge of the kneecap or on the tibial tuberosity, where the tendon attaches to the shin bone.

Because the patellar tendon absorbs so much loading force and impact during activity, it can become strained and develop small tears in the tissue.


Patellar tendinitis can be treated by:
1. Rest from activity
Physiotherapy can strengthen weak or imbalanced muscles that are putting excessive strain on the patellar tendon.

2. A brace to offload the patellar tendon
A patellar tendon brace is usually a strap or brace that is designed to apply pressure to the patellar tendon, which reduces the tension at the end of the patellar tendon.

Here are a commonly available patellar tendon strap and the Donjoy Reaction knee brace, which can help both PFPS and patellar tendinitis.

At Kintec, we carry a wide variety of braces and supports for different conditions relating to the patella, including PFPS and patellar tendinitis.

To learn more about the options that are available, and to see which brace is right for you, ask an expert at the Kintec location nearest you!
