Knee Pain

Dave Jordan

I’m a welder and I have suffered from terrible hip and knee pain from years on steel and concrete floors. I got to the point I had to take pain pills every 4 hours to do my job. After only a week in the ProKinetics® Natural Body Balance™ Insoles I started forgetting to take my pain meds. I am constantly getting better, don’t need pain pills any more, and my coworkers say I’m moving around better. These insoles are just amazing, they’ve changed my life. My wife thanks you too.

Chronic pain ruined my life
Davison, MI

MH - I had knee pain in both knees that seemed to have no cause and was severe enough to require me to stop running.

I have been an athlete all of my life and have always had “undiagnosable” musculoskeletal pains. I had to stop running when I was 23 because I had knee pain in both knees that seemed to have no cause and was severe enough to require me to stop. Fast forward 15 years and for the last year and a half I have been having terrible SI joint pain. I just happened to luck out and find the mortonsfoot.com website while I was researching orthotics I had no idea what Morton’s Foot was, much less that I had it! I have been wearing your ProKinetics insoles for about 2 months now and my pain is virtually gone. It did not happen overnight but gradually my body is adjusting to a proper alignment and that is making all the difference in the world. I am so very very thankful to mortonsfoot.com for their product and their education on this issue. I don’t know what I would have done had I not discovered Morton’s Foot.


You can experience several types of pain in your knees. Lateral (outside) and medial (inside) pain are both common, and so is pain in the area below the knee cap. This kind of pain can range from mild to severe, and typically worsens with use. Most of the time the pain is superficial as opposed to deep. A fractured meniscus is often felt on the inside of the knee, and typically associated with swelling and loss of range of motion. Pain from a fractured meniscus may often be felt as an ache with intermittent sharp pain when loading the knee and walking.

The knee is also subject to torn ligaments, particularly the Anterior Cruciate Ligament (ACL). A torn ACL is an injury that happens instantly, and by most accounts is quite painful. While most knee problems leave the knee stable, a torn ACL destabilizes the knee.

Common Causes

One of the most common results of overpronation and torsional forces in the knee is fractured meniscus.

Opposing rotational forces displaced across the knee are the source of most knee problems. Hip motion directs internal and external rotation of the leg. Hyperpronation causes excessive and prolonged internal rotation of the ankle and calf. This internal rotation from hyperpronation combined with the external rotation directed from the hip cause excessive rotational forces across the knee joint. The use of synthetic rubber shoe soles has magnified this problem as modern shoes provide better traction to the ground. In the days of leather soles, the whole shoe would twist, as evidenced by the common hole worn under the ball of the foot. It is also known that knee injuries happen more easily when wearing shoes with cleats because of the dramatic increase in ground traction.

Rotational forces displaced across the knee are directly responsible for Anterior Cruciate Ligament (ACL) tears from sudden twisting of the knee. Women in sports are more prone to tear or injure this ligament because their wider hips (Q-angle) exaggerate the impact of hyperpronation. Unless caused by impact or the knee being forced into an unnatural position, ligament attachment pain is typically the result of rotational forces across the knee.

The meniscus forms a cup around each condyle (knuckle on the ends of the leg bones). When the knee is exposed to rotational forces, the condyle is pushing harder against the side of the cup which, after millions of cycles finally tears. Sometimes, the torn fragments enter the joint space and cause sharp pain.

Torn ligaments and meniscus fractures require surgical attention, but many of the common forms of knee pain can be fixed relatively easily by improving the mechanical alignment of the hips, knees, ankles and feet.

Runner's Knee

Runner's knee is a very common incident of overpronation and incorporate several different pain locations. Patellar Femoral Syndrome refers to the knee cap to not track correctly over the thigh and shin bones. this pain is usually felt deep under the knee cap. Tight IT bands is also a frequent cause of lateral knee pain among runners. The internal rotation of the leg caused by overpronation increases tension in the Ilio-Tibial ligament that stretches from the Ilium to the Tibia. The Patella is primarily there to protect the knee joint, but the ligaments holding it in place can become inflamed and cause pain. This is usually an overuse problem like the IT band Syndrome that is made worse by overpronation.

Getting to the Root Cause

Rest is probably the most frequent recommendation for knee pain unless the diagnosis has disclosed that surgery may be necessary. Rest, however, is not a cure, and it certainly does not disclose a root cause. In fact even surgery may be a temporary solution unless the root cause is established.

We recommend you spend a few minutes checking your own foot mechanics. You might find that your root cause is what's often called Morton's Toe. As it turns out, Morton's Toe isn't just about the length of your metatarsals, but the fact that the first metatarsal is elevated and therefore not compatible with walking on flat surfaces.
