Knee pain: causes and treatment


Your knee is composed of two joints: one between the thigh bone (femur) and leg bone (tibia) and one between the thigh bone and kneecap (patella). Between the thigh bone and leg bone are two crescent-shaped pieces of cartilage, called menisci. Adding to the anatomical elegance of the knee are fluid sacs (bursae), tendons, ligaments, and muscles.

The knee functions like a hinge joint, meaning that movement is primarily to flex or extend. There is also slight rotational and bending movement.

Knee pain is often the result of repetitive strain caused by overuse and further induced by improper movement patterns.

Common knee injuries include:

  • Meniscus tears

  • Patellar tendinitis (jumper's knee) 

  • Runner's knee

  • Sprained ligaments

  • Injury

  • Infection

  • Osteoarthritis

  • Osteonecrosis

  • Rheumatoid arthritis

When knee pain requires surgery to alleviate pain, our surgeons can perform any number of procedures. We specialize in the latest procedures, including minimally invasive surgery, for total knee replacement, arthroscopy, and more.
