Partial Knee replacement
Partial Knee replacement
Overview
A partial knee replacement is a surgery to replace only one part of a damaged knee. It can replace either the inside (medial) part, the outside (lateral) part, or the kneecap part of the knee. Surgery to replace the whole knee joint is called total knee replacement
Partial knee replacement surgery removes damaged tissue and bone in the knee joint. It is done when arthritis is present in only part of the knee. The areas are replaced with a man-made implant, called a prosthetic. The rest of your knee is preserved. Partial knee replacements are most often done with smaller incisions, so there is less recovery time.
Why the Procedure is Performed
The most common reason to have a knee joint replaced is to ease severe arthritis pain.
Your health care provider may suggest knee joint replacement if:
- You can't sleep through the night because of knee pain.
- Your knee pain prevents you from doing daily activities.
- Your knee pain has not gotten better with other treatments.
Causes of Knee Pain
Various conditions induce knee pain and discomfort, but the most common cause is osteoarthritis of the knee joint. The other conditions that cause knee damage are:- Rheumatoid arthritis
- Inflammatory arthritis
- Knee injury
- Meniscus Tear
- Joint infections
- Haemophilia
- Gout
Treatment Procedure:
Before surgery, you will be given medicine that blocks pain (anaesthesia). You will have one of two anaesthesia types:- General anaesthesia. You will be asleep and pain-free during the procedure.
- Regional (spinal or epidural) anaesthesia. You will be numb below your waist. You will also get medicines to make you relax or feel sleepy.
- Next, the surgeon looks at the entire knee joint. If there is damage to more than one part of your knee, you may need a total knee replacement. Most of the time this is not needed, because tests done before the procedure would have shown this damage.
- The damaged bone and tissue are removed.
- A part made from plastic and metal is placed into the knee.
- Once the part is in the proper place, it is attached with bone cement.
- The wound is closed with stitches.
Benefits of Partial Knee Replacement
- Smaller Incision: A traditional knee replacement surgery involves an incision about 8 inches over the front of the knee. There is more significant dissection necessary to complete the procedure compared to the partial knee surgery. In the minimally invasive partial knee replacement, the incision is about 4 inches, and the amount of dissection and bone removal is much smaller.
- Less Blood Loss: Because of the extent of dissection and bone removal necessary for a total knee replacement, the need for a blood transfusion is relatively common. With the partial knee procedure, a blood transfusionis infrequently needed, and patients do not need to consider giving blood before surgery.
- Shorter Recovery: Both the time in the hospital and the time to functional recovery are less with the partial knee replacement. Patients are known to have been discharged on the day of the procedure, although most often patients are discharged on the first or second post-operative day. With traditional total knee replacement, patients seldom leave before three days in the hospital and may require a stay in an inpatient rehabilitation unit.
- Normal Knee Kinematics: The movement of the knee joint is complex and dependent on the interaction of your joint surface, ligaments, muscles, and tendons that surround the joint. When a full knee replacement is performed, many of these structures are removed to allow for insertion of the artificial knee joint. In a partial knee replacement, more of these structures remain, and therefore the mechanics and movement of the joint remain more normal. In fact, studies have clearly demonstrated in people who have had a full knee replacement on one side and a partial on the other side, their partial knee replacement feels more "normal."
