Your knees are essential to performing many routine everyday activities.

The knee is the largest joint in the body, made up of the lower end of the thigh bone (femur), which rotates on the upper end of the shin bone (tibia), and the knee cap (patella), which slides in a groove on the end of the femur.  

Large ligaments attach to the femur and tibia to provide stability. The long thigh muscles give the knee strength.  

The joint surfaces where these three bones touch are covered with articular cartilage, a smooth substance that cushions the bones and enables them to move easily. All remaining surfaces of the knee are covered by a thin, smooth tissue liner called the synovial membrane. This membrane releases a special fluid that lubricates the knee, reducing friction to nearly zero in a healthy knee.

Disease or injury can disrupt this free-flowing movement resulting in pain, muscle weakness, and restricted function. If the knee is severely damaged by arthritis or injury, it may be difficult to perform simple activities such as walking or climbing stairs.  


Does knee pain keep you from enjoying normal activities?

Arthritis causes pain in hips and knees

Knee pain due to arthritis or injury can make normal everyday activities painful and difficult.

Medications, and/or changes to everyday activities, or the use of walking aids such as a cane may be helpful.

If these measures are ineffective in relieving your pain, ask your doctor about knee replacement surgery, or call the Connecticut Joint Replacement Institute at 1-866-501-CJRI (2574) 

Knee replacement surgery can relieve knee pain, increase motion, and help restore the enjoyment of your favorite everyday activities.
