Can Plantar Fasciitis Cause Knee Pain? Know the Link

Are your heels constantly hurting because of plantar fasciitis, and now your knees have joined the pain party? You’re not alone. Many people dealing with chronic foot pain also start noticing discomfort in their knees over time.

So, can plantar fasciitis cause knee pain? The short answer: yes. The longer explanation involves how pain in your foot can quietly affect your knees, posture, and overall movement. Let’s break down the connection and what you can do to feel better in this comprehensive article.

Can Heel Pain from Plantar Fasciitis Affect the Knees?

Yes, plantar fasciitis (marked by inflammation in the plantar fascia, which is a thick tissue present on the bottom of the foot) can indirectly cause knee pain. The connection lies in the way your body compensates for heel discomfort. 

To avoid pain, you may start walking differently, shifting your weight awkwardly, or favoring one side. These changes in gait and posture can place unusual strain on your knees, resulting in soreness, inflammation, or even injury over time.

How Does Plantar Fasciitis Cause Knee Pain?

Here’s how foot pain can work its way up to your knees:

1. Changed Gait (Walking Pattern):

• Plantar fasciitis often makes you change your walking pattern so that you won’t feel pain in the heels.

• This change can put excess pressure on the knee joint. Over time, this additional stress can cause pain and discomfort in the knee.

2. Muscle Imbalances:

• When avoiding stress on the heel, it makes you overuse your other muscles, especially in the legs and knees.

• This, in turn, leads to muscle strain in the knee, which contributes to pain.

3. Altered Weight Distribution:

• Plantar fasciitis also imbalances the distribution of body weight across the foot. This naturally shifts the excess pressure to the knee joint.

• This compensation leads to strain, which causes pain in the knees.

4. Poor Alignment in the Lower Body:

• Plantar fasciitis can disrupt the proper alignment of the lower parts of the body, like the knee.

• This leads to a risk of strain on the knee joint and prolonged wear and tear, contributing to pain. 

Signs Indicating Your Knee Pain May Be Associated with Plantar Fasciitis

Understanding the link between plantar fasciitis & and knee pain can be difficult, as both conditions share the same symptoms. However, some signs might point to plantar fasciitis as the cause of the knee pain.

If you are not sure your knee pain is connected to plantar fasciitis, look out for these clues:

• Experiencing knee pain after or during the attack of plantar fasciitis.

• Worsening of knee pain after long hours of walking or standing, especially if it develops along with heel pain.

• Knee pain subsides when foot pain is addressed.

• Knee pain increases with certain activities, like running or climbing stairs, as they repeatedly affect the feet and knees.

• Noticing changes in the foot posture and walking pattern.

If you are experiencing any of these issues, see a doctor for an appropriate diagnosis of the exact cause and treatment. 

When to See a Doctor?

Consult the orthopedic specialist or a podiatrist if you experience:

Don’t wait too long. Early medical intervention can help with accurate diagnosis of the cause and a customized treatment plan. This can help you live pain-free and improve your quality of life. 

Treatment for Plantar Fasciitis That Causes Knee Pain

Since the heel pain is often the root issue, treating plantar fasciitis first is the key to relieving knee discomfort.

Conservative Treatments:

1. Rest and Activity Modification:

Give your leg a rest to reduce inflammation in the knee and heel. Avoid activities such as high-impact exercises and prolonged standing, which increase pain, as this promotes healing.

2. Ice Therapy:

Apply an ice pack to the affected area for about 15 to 20 minutes to alleviate pain and inflammation. Do this several times each day.

3. Stretching Exercises:

Practicing these exercises regularly can improve flexibility and alleviate stress on the heel and knee, thus reducing pain.

• Plantar fascia stretches: Hold your toes and pull them gently toward the shin, feeling a stretch in your foot’s arch.

• Calf stretches: Move your one leg back while keeping the heel on the floor, and then bend forward to stretch your calf & Achilles tendon. 

• Towel scrunches: Sit on the chair and put your towel under your feet. Use your toes to gather the towel and bring it towards you.

4. Orthotics (Shoe inserts):

Over-the-counter or custom orthotics can provide great support to your foot’s arch and redistribute strain. This, in turn, helps align the knee and foot. 

5. Supportive Footwear:

Wear supportive shoes with the right arch support & cushioning to improve the alignment of the foot and ankle. This can release the load on the heel.

6. Physical Therapy:

The tailored exercise program by a physical therapist can help strengthen, stretch, and improve the movement of the foot, knee, and ankle. This restores the proper walking pattern.

7. Pain Medications:

Over-the-counter (OTC) pain medicines such as ibuprofen or naproxen can relieve inflammation and pain.

Advanced Treatments:

1. Night Splints:

Wearing it can assist in keeping the plantar fascia stretched throughout the night. This helps alleviate pain and stiffness in the morning.

2. Corticosteroid Injections:

These shots can aid in relieving inflammation, but are generally used for a short period.

3. Surgery (Only if necessary):

If pain persists despite conservative care, surgical options may help:

• Open Plantar Fascia Release: Involves making a large incision (cut) in the heel part to separate the plantar fascia from the heel bone.

• Endoscopic Plantar Fasciotomy (EPF): Involves a small incision and a camera to see and cut the damaged part of the plantar fascia.

Why Physical Therapy Matters Most

Physical therapy isn’t just about treating the foot; it’s about restoring whole-body function. Here’s how it helps:

• Improves walking pattern and weight distribution: Retrains your walk, which improves the posture, balances the weight more evenly, and prevents strain on the feet and knees.

• Builds supporting strength: Exercises that target the supporting muscles, like hamstrings, glutes, quadriceps, and calf, can reduce stress caused by plantar fasciitis and strengthen the stability of the knee joint.

• Improves Flexibility: Stretching exercises such as plantar fascia stretches and calf stretches can improve flexibility in the lower part of the body. This decreases stress on the plantar fascia and knee.

• Alleviates pain and promotes healing: Use manual therapies such as massage or joint and soft tissue mobilization to reduce pain, manage heel and knee limitation, and enhance tissue mobility. Also, utilizes the dry needling technique to release tight muscles, which are responsible for knee and foot pain.

Working with a therapist ensures you’re not just masking the pain, but fixing the root cause.

Risk Factors for Both Plantar Fasciitis and Knee Pain

Recognizing shared risk factors can help you prevent both conditions from developing or recurring.

Risk Factors for Plantar Fasciitis:

All these risk factors put excess pressure on the plantar fascia and restrict movement:

• Obesity

• Foot mechanics, like high arches or flat feet 

• Tight calf muscles

• Prolonged walking, standing, and running

• Improper footwear, like insufficient arch support or cushioning

• Older adults, between the ages of 40-60 years, and especially women

• Certain medical issues, such as arthritis

• High-impact exercises, including running and jumping

Risk Factors for Knee Pain:

All these factors cause excess stress on the knee joint and affect knee alignment:

• Obesity

• Foot mechanics, like poor foot structure & alignment

• With age, osteoarthritis (which causes knee pain) can become highly common, a study says.

• Improper footwear, such as worn-out or poorly fitted shoes

• Tight or weak muscles around the knee

• Previous knee injury

• Prolonged standing, walking, and running

• High-impact activities, like stair climbing and jumping 

Tips for Preventing Both Plantar Fasciitis and Knee Pain

Preventive care goes a long way. Here’s how to stay ahead of the pain:

• Wear supportive footwear, especially during activities, to enhance cushioning and stability.

• Stretch your plantar fascia, calf, and Achilles tendon to loosen tight muscles and strengthen the affected feet.

• Practice simple plantar fasciitis exercises, like arch lifts and toe curls, to support foot alignment and balance, and reduce pressure on the plantar fascia.

• Use custom shoe insoles to provide additional support and keep the feet appropriately positioned.

• Maintain a healthy body weight by eating a well-balanced diet and practicing exercises to alleviate stress on the knees and feet.

• Do not walk barefoot or run on hard surfaces to prevent strain on the knee joint.

• Stretch your hamstrings, hip flexors, and quadriceps regularly to enhance knee flexibility and alleviate strain.

• Always watch for pain signals and don’t overexert, particularly when starting a new exercise regimen.

Small daily habits can prevent big problems later.

Final Thoughts

So, can plantar fasciitis cause knee pain? Yes, it can. When your walking pattern changes to avoid heel pain, your knees often take the hit. But the good news is, treating the source (your feet) can often bring relief to your knees, too.

If you’re experiencing both heel and knee pain, don’t ignore it. Address the problem early with a well-rounded treatment plan, and you’ll be walking pain-free again in no time.

The sooner you take the right action to address both issues, the quicker you will find great relief and feel better.
