Primary Knee Replacement

There are a number of conditions that can lead to a patient requiring a knee replacement, including rheumatoid arthritis, osteoarthritis, or degenerative joint disease. When rest, physio or medication no longer provides adequate relief, a knee replacement may be considered.

The procedure involves making an incision on the front of your leg. The ends of these bones are removed, and replaced with metal and plastic components. Menisci and some ligaments are also removed.

Generally speaking this is a very successful procedure and the replacement will likely last up to 20 years, or possibly even longer. After this time, a revision procedure may be required.

As this surgery involves a significant exposure, you will have a large dressing and occasionally a drainage tube to ensure your knee doesn’t become swollen. This surgery requires a hospital stay of up to seven days after which you will need physical therapy or be given a set of simple exercises to help restore your range of motion and strength. You’ll most likely need a walker, cane or crutches for a few days or weeks until you’re comfortable enough to walk on your own. Most patients are back to light activities within six weeks.
