Benefits of Knee Arthroscopy over Traditional Open Surgery
The advantage of knee arthroscopy surgery over traditional open surgery is that
  • The joint does not have to be opened up fully.
  • For knee arthroscopy only two small incisions are made, one for the arthroscope and one for the surgical instruments to be used in the knee cavity.
  • Reduced recovery time and may increase the rate of success due to less trauma to the connective tissue.
  • Faster recovery times with less scarring, because of the smaller incisions.
  • Irrigation fluid (most commonly ‘normal’ saline) is used to distend the joint and make a surgical space.
