Understanding the Intensity of Pain in ACL Tears: Insights from Science and Clinical Practice


Optimising ACL Tear Recovery: How Specialised Knee Bracing Can Ease Pain and Protect Your Knee


Plantar fasciitis is a common cause of sharp heel pain, especially when taking those first steps in the morning. While this condition primarily affects the foot, many people notice that it’s accompanied by knee pain as well. But can plantar fasciitis really lead to discomfort in the knee? In this article, we’ll explore how heel pain can impact the knee by altering the way we walk and move. Understanding how these areas connect is crucial for effective treatment and preventing future problems.
Plantar fasciitis happens when the plantar fascia—a thick, supportive band of tissue running along the bottom of your foot—becomes irritated or inflamed. The hallmark symptom is a sharp, stabbing pain in the heel, usually most noticeable after periods of rest or first thing in the morning. This pain often develops from repeated stress, such as standing for long hours, wearing unsupportive footwear, or participating in high-impact sports like running.
Those most at risk include runners, people who are overweight, or anyone with certain foot structures. Treatment usually starts with rest, ice, over-the-counter pain relief, and stretching exercises. Health professionals may use ultrasound imaging to examine the thickness of the plantar fascia and questionnaires to measure pain and how much it limits movement. These tools help create a treatment plan tailored to the individual. It’s important to remember that not all heel pain is due to plantar fasciitis—for example, tendon issues may present with similar symptoms but require different treatments.
Our feet are the foundation of our movement, with each step having an impact all the way up the body. When plantar fasciitis makes walking painful, it’s natural to adjust by shifting weight away from the sore heel, changing foot placement, or moving the ankle differently.
These unconscious changes can place extra stress on the knee, especially its inner (medial) side. For example, limited ankle movement (called reduced dorsiflexion) can disrupt the normal transfer of force through the leg, increasing pressure on the knee joint. This explains why people with plantar fasciitis sometimes develop inner knee pain as well.
Research has shown that these changes in walking patterns don’t just affect the feet, but can impact the alignment and function of the entire leg. Limited ankle flexibility is common in those with plantar fasciitis, further highlighting the connection between foot mechanics and knee health. This is why effective care often needs to look beyond just the foot to include the knee and hip as well. Additionally, sometimes persistent heel pain is a sign of a different issue, such as tendon inflammation, making a thorough assessment important.
Managing plantar fasciitis and any related knee pain often requires a holistic approach that focuses on how you move. One of the primary tools is using orthoses—shoe inserts designed to support the arch, improve foot alignment, and distribute pressure more evenly. These can be custom-made or purchased over-the-counter.
Equally important are stretches and strengthening exercises. Regularly stretching the calves and the plantar fascia can improve flexibility and reduce tension. Strengthening exercises for the foot and ankle, like calf raises, towel stretches, and toe curls, help restore healthy movement and support better walking patterns.
Clinical studies confirm that improving foot mechanics can reduce knee pain. By combining supportive orthotics with targeted stretching and strengthening, most people see a significant improvement in symptoms and can prevent further joint problems.
In summary, plantar fasciitis can lead to knee pain by changing how you walk and putting additional stress on your knee joint. If left unaddressed, these changes can affect your entire leg. That’s why early diagnosis and a comprehensive treatment plan—including supportive footwear, targeted stretches, and strengthening exercises—are so important for relieving pain and restoring natural movement.
As research continues to reveal more about the link between plantar fasciitis and knee pain, healthcare professionals can offer better, more holistic care. Remember, not all heel pain is caused by plantar fasciitis, so it’s important to get a proper assessment if symptoms persist. If you’re experiencing heel or knee pain, a professional evaluation can help you find the right treatment and set you on the path to long-term wellness.
