What is Patellofemoral Syndrome?
Patellofemoral Syndrome, also known as patellofemoral pain syndrome (PFPS), is a common knee condition characterized by pain around or behind the kneecap (patella). It is often referred to as "runner's knee" but can affect individuals involved in various physical activities. Patellofemoral Syndrome typically arises due to the misalignment or dysfunction of the patella as it moves along the groove in the thigh bone (femur) called the trochlear groove. It is considered an overuse injury resulting from repetitive stress on the patellofemoral joint.
The exact cause of Patellofemoral Syndrome is multifactorial and can vary among individuals. Some common contributing factors include:
- Muscle Imbalances: Weakness or imbalance in the muscles that surround and support the knee, such as the quadriceps, hamstrings, and hip muscles, can alter the tracking of the patella and lead to increased stress on the joint.
- Abnormal Patellar Alignment or Movement: Issues with the alignment, tracking, or movement patterns of the patella can result in excessive pressure or friction on the underlying joint surfaces. This can occur due to factors like muscle imbalances, tightness in the structures surrounding the knee, or structural abnormalities.
- Overuse and Repetitive Activities: Engaging in activities that involve repetitive knee movements, such as running, jumping, squatting, or climbing stairs, can put excessive stress on the patellofemoral joint, leading to irritation and pain.
- Trauma or Injury: Direct trauma or a sudden injury to the knee, such as a fall or a blow to the knee, can cause inflammation and pain in the patellofemoral joint.
- Biomechanical Issues: Certain anatomical and biomechanical factors can contribute to the development of Patellofemoral Syndrome. These include flat feet (overpronation), high arches, abnormal leg alignment (such as knock knees or bow legs), or tightness in the iliotibial band.
The primary symptom of Patellofemoral Syndrome is pain around or behind the patella. The pain is typically aggravated by activities that involve bending the knee, such as squatting, running, going up or down stairs, or sitting for extended periods with the knee bent. In some cases, swelling or a grinding or popping sensation may also be present.
Treatment for Patellofemoral Syndrome focuses on reducing pain, correcting contributing factors, and promoting proper knee mechanics. It's important to consult with a physiotherapist or chiropractor to receive an accurate diagnosis and individualized treatment plan for Patellofemoral Syndrome. Early intervention has better outcomes.
Treatment may include a combination of the following:
- Rest and Activity Modification: Avoiding activities that aggravate symptoms and modifying activities to reduce stress on the knee joint.
- Physical Therapy: Neuro Muscular Strengthening exercises for the quadriceps, hamstrings, hip muscles, and core to improve overall stability and correct muscle imbalances. Stretching exercises can also help improve flexibility and relieve tightness in the surrounding structures.
- Patellar Taping or Bracing: The use of taping techniques or braces can help improve patellar alignment, reduce pain, and provide support to the joint during activities.
- Biomechanical Assessment and Correction: Evaluating and addressing any underlying biomechanical issues, such as foot pronation or leg alignment, to optimize knee mechanics and reduce stress on the patellofemoral joint.
- Gradual Return to Activity: Gradually reintroducing activities and sports while monitoring symptoms and ensuring proper technique and form.
"Timing" is the key in the effectiveness of the therapy -off all the above strategies, which will work and in combination with what will be given and addressed by your expert physiotherapist or chiropractor.

They can assess the specific factors contributing to your condition and provide appropriate guidance and interventions to alleviate pain and promote recovery.
What are the symptoms and causes of Patellofemoral Syndrome?
Symptoms of Patellofemoral Syndrome (PFS):
- Anterior Knee Pain: The primary symptom is pain in the front of the knee, around or behind the kneecap (patella). The pain may be dull, aching, or sharp in nature.
- Worsening Pain With Activity: Pain typically increases during activities that involve bending the knee, such as running, jumping, squatting, kneeling, or climbing stairs. It may also worsen after prolonged sitting with the knees bent.
- Pain During Descent: Descending stairs or hills often exacerbates the pain due to increased stress on the patellofemoral joint.
- Crepitus or Grinding Sensation: Some individuals may experience a grinding, cracking, or popping sensation in the knee joint when moving the knee.
- Swelling or Inflammation: Inflammation around the patella or in the joint may lead to localized swelling or a feeling of fullness in the knee.
- Stiffness or Reduced Range of Motion: The knee joint may feel stiff or limited in its range of motion, especially after periods of inactivity or upon waking up.
Causes and contributing factors of Patellofemoral Syndrome:
- Muscle Imbalances: Weakness or imbalances in the muscles around the knee, particularly the quadriceps and hip muscles, can affect the alignment and tracking of the patella, leading to increased stress on the patellofemoral joint.
- Patellar Malalignment or Tracking Issues: The patella may not move smoothly along the trochlear groove of the femur, resulting in abnormal stress distribution and increased pressure on the joint surfaces.
- Overuse or Repetitive Activities: Engaging in activities that involve repetitive knee movements or excessive loading of the patellofemoral joint, such as running, jumping, squatting, or cycling, can contribute to the development of PFS.
- Biomechanical Factors: Certain anatomical or structural factors can contribute to PFS. These include flat feet (overpronation), high arches, abnormal leg alignment (such as knock knees or bow legs), or tightness in the iliotibial band or other surrounding structures.
- Trauma or Injury: Direct trauma to the knee, such as a fall or impact, can cause inflammation and pain in the patellofemoral joint.
- Poor Training Techniques or Equipment: Improper running or movement mechanics, inadequate warm-up or cool-down routines, inappropriate footwear, or sudden increases in training intensity or volume can increase the risk of developing PFS.
- Pre-existing Conditions: Certain conditions, such as patellar instability, patellar tendinitis, or arthritis, may predispose individuals to PFS.
