What causes knee pain?
There are many causes of knee pain. Some of the most common include patellar syndrome, arthritis, ligament injuries, cartilage damage (meniscus), tendonitis and bursitis. Some of these problems are caused by direct injury, and some may be the result of wear and tear over time.
Is my knee pain related to my feet?
Abnormal foot function can cause several types of knee pain. Your feet are the foundation of every step you take. Problems with the function of your feet can affect everything in your body, including your knees, back and hips.
According to some studies, excessive flattening of the feet (pronation) is the foot problem most often mentioned in the medical literature as being associated with knee pain. This happens because pronation of the foot forces the knee to turn inward so that it adopts an abnormal position.
Here is a little experiment you can do to illustrate this point.
- Stand with your shoes and feet flat on the floor.
- Look at the position of your kneecaps.
- Now roll your feet outward and stand on the outside of your feet.
- Note the position of your kneecaps again and notice how they point outward, away from each other.
- Flatten your feet again and note how your kneecaps move inward.
When your feet roll inward or outward, the leg and knees in turn rotate inward or outward, leading to increased stress on the knees.
Treatment for knee pain can be as varied as the number of causes associated with it. Before undergoing treatment for your knee pain, it is very important that you understand the cause of your condition. Our first task is to determine if your foot function may be contributing to your knee pain. To do this, we will conduct an examination and possibly prescribe a temporary brace to determine how it affects your pain. If we believe that your knee pain is not related to foot function, we will refer you to an appropriate specialist.
How can foot orthotics help reduce knee pain?
If after a medical examination we feel that your knee pain may be related to foot function, we may recommend custom-made foot orthotics and shoe modifications. Good custom-made orthotics can address the underlying cause of your knee condition. In fact, several studies have shown the dramatic effect that orthotics can have on knee problems.
Studies conducted in 1997, 2002 and 2004 found strong scientific evidence that orthotics with specific types of shimming are effective in reducing pain in people with osteoarthritis of the knee. In a 2005 study of 30 people with osteoarthritis of the knee, subjects received foot orthotics with a 5 degree lateral shim. After six weeks, all subjects had some relief and 28 of them found the orthoses comfortable.
In a 2003 study of 102 sports patients with patellar syndrome, 76.5% of patients experienced improvement after two to four weeks with custom-made foot orthotics.
In 2004, a study showed a significant improvement in the pain of the syndrome with the use of foot orthotics.
What type of orthotics work best to relieve knee pain?
Studies have shown that the best type of orthosis varies depending on the type of knee problem you are experiencing. A person experiencing pain inside the knee needs a very different orthotic than a person experiencing pain outside the knee.1-6 In addition, orthoses for knee pain often require adjustments after the patient has been wearing them for a few weeks. For most (but not all) knee problems, the orthotics must adhere very well to the arch of the foot (known as strong-bond orthotics). All of this is why it is absolutely essential that everyone who prescribes orthotics must be an expert in molding, prescribing and troubleshooting foot orthotics.

What is Patellar Syndrome?
Patellar syndrome is a common knee problem. If you have this condition, you will experience pain in your patella and surrounding areas. The pain may get worse during activity or after sitting for a long period of time. You may experience pain in one or two knees.
The exact cause of patellar syndrome is not known. It is suspected to be related to the way your patella moves on your thigh bone (femur). Too much pronation is one of the causes of a patella that does not move properly on the thigh bone.
