The knee joint is made up of three bones: the femur, tibia, and patella. The ends of the tibia and femur are covered with a thin cartilage allowing a smooth joint surface and reduced friction during movement.  Additionally, there are two C-shaped menisci in the knee that serve to absorb shock and evenly distribute forces across the knee.  Finally, various ligaments, tendons, and muscles provide support and stability.

  • Acute trauma
    • Most common mechanism of injury is sudden rotation with bent knee
  • Chronic load
    • Repetitive overload
    • Pronation
    • Degenerative joint disease


  • Knee pain/swelling
  • Locking, popping, clicking in the knee
  • Decreased range of motion
  • Weakness/instability in the knee


  • History
  • Orthopedic exam
  • MRI – most sensitive


The outer 1/3 of the meniscus has a blood supply (red zone) and a tear in this area may heal on its own.  The inner 2/3 of the meniscus lacks a blood supply (white zone) and typically does not heal without surgery.

  • Non-surgical
    • Rest, ice, elevation, NSAIDs to control inflammation and reduce pain
    • Physical rehabilitation to include knee stability exercises
    • Assessment of foot pronation and fitting of orthotics, if necessary
  • Surgical – arthroscopic
    • Partial/total meniscus removal
    • Bone marrow derived stem cell injection
