Meniscus tears are very common in the human knee. They can result in the need for: repair, partial removal or transplantation. See here for details about Meniscus Replacement or Meniscal Transplantation. For info about repairs or partial removal (meniscectomy) read on... Torn meniscal cartilage can be asymptomatic or severely painful and limiting. Just having a meniscus tear doesn't necessarily determine whether or not the treatment should include knee surgery or invasive care. The treatment decision for medial or lateral meniscus tears is based on several factors, including, but not limited to:

  1. age of the tear, ie acute or chronic (blood supply, inflammation, cyst formation, etc.)
  2. type of tear: oblique, horizontal, vertical, peripheral, undersurface, complex, radial, flap, bucket-handle, discoid, displaced, degenerative. etc.
  3. location of the tear: posterior horn, anterior horn, middle third, inner zones, menisco capsular junction
  4. age of the patient: younger ages do better with meniscus repair or meniscal repair
  5. presence of other structural problems in the knee: Baker's cyst, plica, meniscal cyst, ACL tear, malalignment
  6. presence of other medical diseases or issues: gout, pseudogout, arthritis, AVN avascular necrosis
  7. physical demands, sports activities and patient expectations
  8. previous treatments

Less than a year after having my rotator cuff repaired by Dr. Hyman my shoulder is better than the one that wasn't injured. The recovery time was so fast my wife thinks I have some kind of super healing power.
