A Healthy Meniscus

Your meniscus is crescent-shaped cartilage, cupped to help hold bones in place. You have one on each side of your joint-on the outside, the lateral meniscus, and on the side closest to your other knee, the medial meniscus. When healthy, the meniscus absorbs shock by cushioning and distributing forces across your joint. It also helps stabilize your knee by controlling its rotation. The outer edge of the meniscus is supplied by nutrient-rich blood.

Surgical Procedure

Since the muscles around the joint must be relaxed to allow easy access into the joint, a general anaesthetic is used. The skin is sterilized and through small puncture wounds, the arthroscope is inserted and used to confirm the diagnosis of such abnormalities as torn menisci, tears of ligaments, loose bodies or fragments within the joint, inflammation of the joint lining, and articular cartilage injury or damage. Arthroscopic surgery is an extension of the diagnostic technique of arthroscopy. Through additional small puncture holes, tiny instruments are inserted into the joint and surgery can be performed while the surgeon watches on a television screen. It is possible to treat meniscal injuries by removal of loose fragments, or in certain cases by repair. Loose pieces or fragments can be removed from within the joint. The knee cap can be smoothed out or realigned in certain patients. The inflamed joint lining in certain types of arthritis can be trimmed away. Other procedures, including ligament repair and fusion of certain joints can be carried out with the aid of an arthroscope.

  • Shorter hospitalization (usually day surgery)
  • Minimal post operative pain
  • Minimal scarring
  • Faster recovery

All surgeries carry some risk...

  • Infection
  • Swelling
  • Deep vein thrombosis
  • Hematoma
Post-Operative Care

Your knee will be swollen and a tensor bandage will be applied.

  • Loosen if tight or ankle swells
  • Elevate leg

Bandages may be removed 3-4 days after surgery.

  • Do not remove stri-strips
  • Keep area clean
  • Small bandage may be applied
