Why Knee Pain Is So Common & What You Can Do About It

Why Knee Pain Is So Common & What You Can Do About It

Knee pain is one of the most common musculoskeletal problems worldwide. Studies estimate that around 25–30% of adults experience knee pain at some point in their lives, and the prevalence increases significantly with age and body weight.

For many people, knee pain doesn’t appear suddenly after an injury. Instead, it develops gradually due to stress, inflammation, and long-term strain on the joint.

Understanding why knee pain happens is the first step toward finding real relief.

The Knee: One of the Most Stressed Joints in the Body

The knee is a complex joint made up of bones, cartilage, ligaments, tendons, and muscles working together.

Every time you walk, climb stairs, or stand up from a chair, your knees absorb large forces. In fact:

  • Walking puts 1.5× your body weight on the knee

  • Climbing stairs can put 3–4× your body weight on the joint

  • Squatting can increase the load to 7–8× your body weight

Over time, this constant pressure can lead to irritation and pain.

 

Common Causes of Knee Pain

Knee pain can arise from several different factors. Some of the most common include:

1. Patellar Tracking Issues

The kneecap (patella) should glide smoothly within a groove in the femur. If the surrounding muscles are weak or tight, the kneecap may shift slightly out of alignment.

This can cause:

  • Pain around the front of the knee

  • Clicking or grinding sensations

  • Discomfort when climbing stairs or sitting for long periods

2. Tendon Strain

Tendons connect muscles to bones. Repetitive movement, sports, or sudden increases in activity can strain these tissues.

This condition is often called patellar tendinitis, sometimes referred to as jumper’s knee.

3. Osteoarthritis

Osteoarthritis is the most common form of arthritis, affecting millions of people worldwide. It occurs when the cartilage that cushions the joint gradually wears down.

Symptoms may include:

  • Stiffness

  • Swelling

  • Reduced mobility

  • Pain during movement

4. Excess Mechanical Load

Extra body weight increases stress on the knees. Research suggests that each additional kilogram of body weight can add roughly 4 kg of pressure on the knee joint during movement.

This means small weight changes can significantly affect knee strain.

 

Small Changes Can Make a Big Difference

Managing knee pain often involves a combination of simple strategies:

Strengthening the Supporting Muscles

Strong quadriceps, hamstrings, and glutes help stabilize the knee joint.

Reducing Excess Load

Even modest weight loss can decrease joint stress.

Improving Joint Alignment

Supporting the kneecap and surrounding structures can help distribute pressure more evenly across the joint.

 

How Knee Braces Can Help

Knee braces are commonly used to improve stability and reduce strain during daily activities or exercise.

A well-designed brace can help:

  • Support the kneecap

  • Improve alignment during movement

  • Reduce pressure on irritated tissues

  • Increase confidence when walking or exercising

Many people find that using a supportive knee brace allows them to stay active while protecting the joint.

 

Supporting Your Knees for the Long Term

Knee pain doesn’t necessarily mean you have to stop being active. In many cases, the right combination of support, strengthening, and smart movement habits can significantly improve comfort and mobility.

If you experience persistent knee discomfort during walking, exercise, or everyday activities, additional joint support may help reduce strain and make movement easier.

Patellaplus was designed specifically to provide targeted support for the kneecap and surrounding structures, helping distribute pressure more evenly across the joint.
