What is Runner’s Knee (Patellofemoral Pain Syndrome)

Patellofemoral pain syndrome (PFPS), often referred to as runner's knee due to its prevalence among runners, is characterized by a dull pain that occurs around or behind the kneecap. While it's common among runners, it can affect anyone participating in an activity that requires repeated knee flexion, such as jumping, walking, or even biking. Here's a closer look at this common knee problem, the causes, common symptoms, how it's treated, and some helpful prevention tips.

Causes of PFPS

Pinpointing just one cause of runner's knee is difficult. PFPS may be a biomechanical problem, such as a high-riding patella within the femoral groove. Improper patellar tracking, leading to PFPS, can be caused by worn cartilage in the knee, which reduces shock absorption, flat or high arched feet, which offer less cushioning for knees, and tight or weak musculature. In some cases, it's simply the repetitive force that comes with running that can bring on an attack of PFPS.

The Common Symptoms

One or both of your knees may be affected by runner's knee. In most cases, it strikes recreational, young runners, and is more common among women than men. It's thought that women are more susceptible due to wider hips, which causes a greater angling from the femur to the knee, resulting in more stress on the kneecap. Some of the common symptoms of PFPS include:

• Tenderness around or behind the patella
• Pain that occurs in the back of the knee
• A feeling that the knee is going to give out
• Cracking/popping sensation in the knee

For most people with runner's knee, uneven terrain, going up hills, or descending steps can result in increased pain to the knee.

Treating Runner's Knee

Using strengthening exercises to stabilize the kinetic chain is one of the best ways to treat the symptoms that come with runner's knee; in addition to leg musculature, strengthening the hips, abdominal muscles, and quadriceps can provide excellent results. Gait modification for runners may also prove useful for reducing the symptoms of runner's knee. Physical therapy is a great resource to provide appropriate exercises, gait training, and pain management techniques.

Prevention Tips

For individuals who haven't experienced runner's knee, stretching, stabilization, strengthening, and correcting improper gait can help prevent PFPS. Focusing on the core, hips, and quads can all be helpful to avoid runner's knee and many other injuries. If you're dealing with shooting or sharp pain, taking several days off can help prevent further problems. Running on softer surfaces, gradually working on adding hills to a running program, and avoiding drastic increases in running mileage can also prevent runner's knee. It's a good idea to visit a running shop to ensure you have the right shoes for your gait and foot type.
