Patellofemoral Pain Syndrome (PFPS), often referred to as “runner’s knee,” is a common knee condition that affects people of all ages and activity levels. While overuse is a significant contributor, several other factors can lead to the development of PFPS. In this blog, we will explore the common causes of PFPS beyond overuse and discuss treatment options to alleviate this knee condition.

Understanding Patellofemoral Pain Syndrome
Before we delve into the causes, let’s briefly understand PFPS. This condition occurs when the patella (kneecap) rubs against the femur (thighbone) improperly, causing pain and discomfort in the front of the knee. PFPS is often associated with activities that involve bending the knee repeatedly, but it can also result from various factors.
One significant cause of PFPS is muscular imbalances around the knee joint. Weakness or tightness in certain muscle groups, such as the quadriceps, hamstrings, or hip muscles, can alter the patella’s alignment and increase stress on the joint. Physical therapy to strengthen and stretch these muscles is a vital component of treatment.
Anatomical and biomechanical factors can predispose individuals to PFPS. These include:
Patellar Alignment: An abnormal patellar alignment, often referred to as patellar maltracking, can contribute to PFPS. It can cause uneven pressure on the patellofemoral joint and lead to pain.
Flat Feet or High Arches: Abnormal foot arches can affect how forces are distributed through the lower extremities, potentially leading to PFPS.
Leg Length Discrepancy: A significant difference in leg length can lead to altered biomechanics and PFPS in some cases.
Trauma or Injury
While overuse is a common cause of PFPS, acute trauma or injury to the knee can also trigger the condition. A direct blow to the kneecap or a fall can damage the structures within the patellofemoral joint, leading to pain and dysfunction.
Inappropriate or worn-out footwear can contribute to PFPS. Shoes with inadequate support or cushioning may not absorb shock properly during activities, increasing the risk of knee pain. Ensuring proper footwear for your specific activity can help reduce the risk.
Patellofemoral Joint Disorder
Some individuals may have an underlying patellofemoral joint disorder that predisposes them to PFPS. These disorders may include chondromalacia patellae, which involves softening or damage to the cartilage on the back of the patella. Comprehensive evaluation and treatment are necessary to address such conditions.
Overtraining and Sudden Changes in Activity
While overuse is a common cause, overtraining or sudden, intense changes in physical activity levels can also contribute to PFPS. It’s essential to gradually increase the intensity and duration of physical activities to allow the body to adapt.
Patellofemoral Pain Syndrome Therapies
Effective treatment for PFPS involves addressing the underlying causes. Common therapeutic approaches include:
Physical Therapy: A physical therapist can design a customized exercise program to improve muscle strength, flexibility, and alignment.
Orthotics: Custom orthotic inserts can help correct biomechanical issues related to foot arches and leg alignment.
Knee Bracing: In some cases, a knee brace or patellar taping may provide support and alleviate pain during activities.
Rest and Activity Modification: Reducing or modifying activities that exacerbate PFPS symptoms is essential for recovery.
Anti-Inflammatory Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) can help manage pain and reduce inflammation.
Injections: In cases of severe pain, corticosteroid injections may be considered.
Surgery: Surgery is typically a last resort and reserved for severe cases where conservative treatments have not provided relief.
Patellofemoral Pain Syndrome is a multifactorial condition that goes beyond simple overuse. Understanding the various causes, from muscular imbalances to biomechanical factors, is essential for effective treatment and prevention. If you’re experiencing knee pain or suspect PFPS, seek evaluation and guidance from a healthcare provider. With proper diagnosis and a tailored treatment plan, you can address the underlying causes and find relief from PFPS, allowing you to enjoy pain-free activities once again.
