Understanding Patellofemoral Pain Syndrome: Symptoms, Causes, and Effective Exercises for Relief 

Introduction 

Patellofemoral Pain Syndrome (PFPS), commonly referred to as runner's knee, is a prevalent condition characterised by pain and discomfort around the front of the knee joint. It often affects athletes, especially runners, as well as individuals engaged in activities that involve repetitive knee movements. This week we look into the symptoms, causes, and exercises that can help alleviate the discomfort associated with Patellofemoral Pain Syndrome.

Symptoms of Patellofemoral Pain Syndrome 

The usual symptoms of PFPS is a dull, aching pain that is felt around or behind the patella (kneecap). This pain is usually aggravated by activities that involve bending the knee, such as running, climbing stairs, squatting, or sitting for extended periods with the knee bent. Other common symptoms include: 

• Pain During Physical Activities: Discomfort is often experienced while engaging in exercises or sports that stress the knee joint, making it difficult to perform these activities without pain. 
• Pain After Prolonged Sitting: Individuals with PFPS may experience pain and stiffness in the knee after sitting for an extended period with the knee bent, such as during a long car ride or after watching a movie. 
• Cracking or Popping Sensation: Some people with PFPS report sensations of cracking, popping, or grinding in the knee joint when bending or extending the knee. 
• Swelling: While swelling is not a prominent feature of PFPS, some individuals may experience mild swelling around the knee due to inflammation. 

Causes of Patellofemoral Pain Syndrome 

PFPS typically develops when there is an imbalance in the forces acting on the patella as it glides over the femoral groove. Several factors can contribute to this imbalance: 

• Muscle Imbalances: Weakness or tightness in the muscles around the knee, particularly the quadriceps and hamstrings, can lead to improper tracking of the patella. 
• Overuse and Repetitive Movements: Engaging in activities that involve repetitive bending of the knee, such as running downhill or excessive jumping, can strain the patellofemoral joint. 
• Misalignment: Structural issues like malalignment of the patella, flat feet, or high arches can alter the way the patella moves, leading to increased pressure on certain areas. 
• Improper Footwear: Inadequate footwear or shoes that do not provide proper support can contribute to PFPS by affecting the alignment of the lower body. 

Exercises to Relieve PFPS Symptoms 

Engaging in specific exercises can help alleviate the symptoms associated with PFPS and promote better knee joint function. However, it's essential to consult a healthcare professional or physical therapist before starting any exercise regimen. Here are some exercises that may be beneficial: 

• Quadriceps Strengthening: Straight leg raises, leg presses, and squats can help strengthen the quadriceps muscles, which play a crucial role in stabilising the patella. 
• Hamstring Stretches: Gentle hamstring stretches can improve flexibility and help alleviate muscle imbalances around the knee. 
• Glute Strengthening: Exercises that target the gluteal muscles, such as hip bridges and clamshells, can help stabilise the pelvis and improve overall lower body alignment. 
• Patellar Taping: Applying tape to the patella can help support its proper alignment during activities, reducing pain and discomfort. 
• Lateral Hip Strengthening: Exercises like lateral leg raises can strengthen the hip abductor muscles, which contribute to proper alignment and tracking of the patella. 
• Calf Stretches: Stretching the calf muscles can alleviate tension and indirectly affect the knee joint's mechanics. 

Patellofemoral Pain Syndrome can be a challenging condition to manage, but with the right approach, including proper exercises and addressing underlying muscle imbalances, individuals can find relief from the discomfort. It's crucial to work closely with a physiotherapist or sports specialist, to develop a personalised treatment plan that suits your needs and promotes a safe return to physical activities.
