Patellofemoral Pain Syndrome
A brief breakdown of Patellofemoral Pain Syndrome, commonly known as "runner's knee" or sometimes "move goer's knee".
What is Patellofemoral Pain Syndrome?
Patellofemoral pain syndrome (PFPS), commonly known as "runner's knee" or sometimes "move goer's knee" is a condition where you feel pain around or behind your kneecap. It’s one of the most frequent causes of knee pain, especially in the front of the knee, and can affect athletes and non-athletes alike. Research suggests it impacts up to 1 in 3 adults at some point in their lives, making it a significant concern for active individuals.
Symptoms to Watch For
The main symptom is pain in the front of the knee, particularly around the kneecap. This pain often worsens during activities that involve bending the knee under load, such as running, jumping, squatting, or climbing stairs. Some people also experience discomfort after sitting for long periods with their knees bent, sometimes called "theater sign" or "movie sign." Other signs might include swelling, a grinding or popping sensation, or a feeling of weakness or instability in the knee.
Common Causes
The evidence leans toward PFPS being caused by a mix of factors, including:
Overuse from repetitive activities like running or jumping.
Muscle imbalances, especially weakness in the quadriceps or hip muscles, which can affect how the kneecap moves.
Structural issues, such as a misaligned kneecap or flat feet (overpronation).
Biomechanical problems, like abnormal walking patterns.
It’s also more common in women, possibly due to differences in hip structure, and in young adults in their twenties and thirties, often linked to higher activity levels.
How It’s Treated
Treatment usually starts with conservative measures. Physical therapy is a key part, focusing on exercises to strengthen the muscles that cross the knee, especially those that also cross the hip, improve flexibility, and correct movement patterns. Modifying activities that worsen the pain are also important in the short term. In some cases, orthotics (shoe inserts) or tapellar taping might help. Most people find relief without needing surgery, but if symptoms persist, further evaluation may be needed.
