Top Running Injury No. 9: Weak Knees

Weak KneesThis is the ninth article in a 10-part series exploring some of the most common injuries faced by runners.

If you run a lot, it’s inevitable that your knees will suffer a great deal of wear and tear. Not only does this result in a great deal of discomfort and pain, it can also greatly reduce their strength. Weak knees are a common problem with runners, but that doesn’t mean you can’t still enjoy your favorite activity. Medi-Dyne has some information on what causes this condition and how you can manage it.


There are several reasons why weak knees occur in runners. Here are some of the more common ones:

  • Torn ligaments or cartilage
  • Knee joint infection
  • Arthritis
  • Knee sprains
  • Knee strains

If you experience a burning sensation, redness or swelling and stiffness in the knee, you hear a popping noise when you bend your knee, or you can’t straighten your knee properly, then you should talk to a doctor who can help you determine the right course of treatment.
