Arthroscopy


Key Points

Arthroscopy is a minimally invasive way to do surgery on joints.

This technique can be used as a tool to diagnose a problem of a joint when other noninvasive tests are inconclusive.

A surgeon can more thoroughly examine a joint and more accurately treat the problem.

The patient has less pain and will recover quicker than with traditional surgery.

 

Indications

  • Joint diseases
    • Shoulder:  osteochondrosis flap removal, diagnostic arthroscopy, biceps tendon tears/tendonitis, instability of the shoulder due to tearing of collateral ligaments
    • Elbow:  fragmented coronoid processes, osteochondrosis
    • Stifle:  cruciate ligament tears, osteochondrosis, long digital extensor tendon avulsion
    • Tarsus:  osteochondrosis

 

Reasons to have surgery done arthroscopically

  • The surgeon can see the diseases better and thus treat the problem more thoroughly
  • Less invasive procedure
    • Less hair is generally shaved
    • Less pain
    • Less scar tissue develops, therefore better range of motion
    • More rapid return to function of the limb
    • Surgery can be done more rapidly in some cases, thus less anesthesia time for patient

     

How the procedure is done

  • A square region of hair is clipped over the joint
  • The joint is distended with sterile fluid
  • The ports for the camera and instruments are created with a couple of very small stab incisions
  • A camera (arthroscope) is inserted into the joint
  • A second port is made over the area of the joint that needs treatment
  • Abnormal tissue is removed using small forceps, or an arthroscopic power shaver

Potential complications

  • Inability to perform surgery arthroscopically, thus necessitating an open surgical approach to the joint (this is uncommon)
  • Swelling from leaking of fluid from the joint during the procedure; this is not really considered a complication, but is expected after this type of surgery and will resolve within 1 to 2 days
  • Infection – rare
  • Anesthetic death – rare
