How Common is Knee Pain?

Knee pain is one of the most common ailments amongst athletes and non-athletes alike.  People of all ages are also affected by knee pain.  The reason for the prevalence of knee pain is because the knee supports most of the body’s weight and is involved with both daily activities and movement during sports.

Knee pain is typically caused by:

  • knee injuries
  • overuse
  • age
  • natural wear and tear


It’s understandable that activities and sports that involve sharp turns, lifting weights and the like would cause strain on the knee. However, many athletes do not know that running is a very stressful activity on the knee, which is why sports that involve running also tend to have higher risk of knee pain and knee injuries.  This can be during both contact (such as football) and non-contact (such as jogging) sports.

People in professions that involve a lot of lifting, walking or kneeling may also feel the effects of knee pain.  A great example of this is in mail carriers, a profession widely known to be hard on the knees.  Other types of overuse activities such as gardening and recreational activities like hiking can also stress the knee.

As mentioned above, the natural wear and tear of the knee from age and use can also lead to knee pain, which contributes to the widespread presence of knee pain.  Other physical factors, such as very tall individuals, may also be a cause of knee pain.

As you can see, there are many ways that all types of people may experience knee pain.  To help minimize your risk of knee pain (or to help reduce knee pain), check out our knee braces and supports.

Have You Seen These DonJoy Knee Brace Accessories?

Did you know that many of our DonJoy knee braces can be used with accessories to improve comfort and use? You can get items such as knee brace undersleeves and knee brace covers.

Our most popular knee brace accessory is the DonJoy Cotton/Lycra Knee Brace Undersleeve. It helps cushion your knee brace against your skin to prevent chaffing. A knee brace undersleeve also absorbs moisture from sweat during warmer months and keeps your knee warmed up during cooler months.  Another great option is the DonJoy Neoprene Knee Brace Undersleeve, which is made of a more premium, breathable material. Both options are washable!

For knee braces that are at risk of getting dirt in the hinges, we highly recommend the DonJoy Sports Knee Brace Cover.  This helps lengthen the life of your knee brace from debris and pads the frame and hinge of the brace – which is great for the brace and during contact sports where your knee brace may impact other athletes.

Why Knee Brace Size is Important

People buy knee braces to help reduce knee pain, prevent injury and to protect their knees.  However, what people often underestimate is the importance of finding the right knee brace size.  Wearing the incorrect size of knee brace can prevent the support from being effective, or may even add to your risk of injury.  This is true for knee brace sizing that is too tight or too loose on your leg.
