The knee, one of the largest and most complex joints of the body, is designed for mobility and stability. The knee is basically a hinge joint between the femur and the tibia. It allows the motion of flexion and extension. A slight degree of rotation and lateral (sideways) motion is allowed when the knee is flexed, but since the knee lacks the bony stability of the hip joint, it must depend upon muscles and strong ligaments to stabilize the aforementioned bones together.

Although the knee is one of the largest joints in the body, it is certainly not the strongest. Because of its exposed position and the great functional demands imposed on it by weight-bearing stress such as walking, running and jumping, the knee suffers injury affecting its function and stability more frequently than any other joint.

Joints should be noiseless, so having noise coming from the joint usually means there is some wear and tear on the surfaces of the bones. A noise when you bend or straighten the knee usually comes from wearing away the undersurface of the kneecap rubbing along the thighbone.

In physical therapy, we have found the muscles on the front of the thigh do not contract in the normal coordinated fashion, causing the kneecap to move out of its normal “groove.” This causes a wearing away of the undersurface of the cartilage of the kneecap, and after some time will sound like sandpaper scraping with movement. Oftentimes, this noise can be decreased or eliminated by reeducating the muscles so the movement occurring at the kneecap is aligned back in the "groove".

If your knee occasionally buckles or locks, you should see your physician as this could be due to a variety of causes. Oftentimes, this is associated with a mechanical problem or a “loose body” in the knee, which means something in the joint is interfering with normal function.

Swelling usually follows an injury and means an inflammatory process has started, as this is the body’s way to heal. Sometimes swelling may also indicate bleeding inside the joint.

Conditioning of the body tends to be very specific, which means if you are a runner, your muscles and joints are conditioned to running, not necessarily mountain climbing or swimming. So, if you want to get your knees in shape to do lifting activities, do an exercise program involving incrementally more challenging lifting activities. Likewise, if you want to get your knees in shape for skiing, do exercises and activities most like movements used in skiing.

Use common sense and listen to your body. Aim for prevention whenever possible and seek out help when appropriate. Your body does communicate to you. You just need to listen!
