Arthroscopy
Knee arthroscopy is used in the diagnosis and
treatment of a number of knee disorders and injuries. One common use is in the treatment of
meniscal tears. Under normal conditions,
the menisci, the c-shaped pieces of cartilage resting between the femur and
tibia provide cushioning and stability for the knee joint, injuries or
arthritis can cause the menisci to become torn resulting in knee pain,
swelling, and diminished range of motion.
Knee arthroscopy is often preformed to remove the damaged portion of the
meniscus. When you arrive to the
hospital for your procedure, an intravenous line will be started and you may be
given a sedative to help you relax. The procedure
can be performed under spinal anesthesia, which keeps you numb from the waist
down. Local anesthesia which keeps your
knee area numb or less commonly general anesthesia which renders you unconscious
for the duration of the procedure. An arthroscopic
meniscectomy usually takes between 45 to 90 minutes. The surgeon will gain access to your knee
joint by using sharp instruments called trocars to make two or three small openings
or ports; here the surgeon will inject a sterile solution in to the joint to
push the surfaces apart allowing the structures inside the joint to be viewed
more easily. Next your surgeon will
insert the arthroscope and other instruments through the various ports where in the arthroscopes
camera are magnified and projected on to the video monitor. Your surgeon will carefully examine the
inside of your knee joint, locate the damage, remove any loose or severely
injured parts and use a shaving instrument to smooth any jagged edges, well it
may be possible to repair the meniscus with small stitches. In most cases, the damaged portion must be
removed. At the end of the procedure, your
surgeon will again carefully examine the entire knee for any areas of bleeding
or any other damage, remove the arthroscope and other instruments and close
each of the key hole incisions with a few sutures. After your surgery, you will be taken to the
recovery area for monitoring, where you will be given pain medications as
needed. Most patients leave the outpatient
surgery unit within a few hours.
