Knee pain is a common complaint heard by physical therapists. A variety of factors can contribute to knee pain from runner’s knee and meniscus tears to sprained ligaments and tendinitis.
The most common knee injuries are those involving the “unhappy triad.”
The anterior cruciate ligament (ACL)
The medial collateral ligament (MCL)
The medial meniscus (MMT)
Of these three, ACL injuries are the most common, typically damaged because of side-to-side movements. Even a slightly awkward placement of the foot can put too much stress on the ACL, causing a sprain or a tear.
The knee has two other ligaments outside of the Unhappy Triad: the posterior cruciate ligament (PCL) and the lateral collateral ligament (LCL). PCL injuries are not common. LCL injuries usually occur with a sharp blow to the outside of the knee, and can be extremely painful.
My Knee Hurts When I Walk or Run
If you experience pain when walking or running, you may have what’s called, “runner’s knee.” Runner’s knee is not a specific injury and it’s not just for runners, anyone can suffer it. Several factors can trigger runner’s knee including:
A hit to the knee
Your bones are misaligned
My Knee is Swollen
If your knee is swollen, this means you have excess fluid accumulating around the joint. This can be from an injury, overuse or as a result of an underlying medical condition. Back To Injury Rehabilitation
