A total knee replacement (TKR) is a resurfacing operation of the knee. The damaged joint lining is removed and replaced with a metal or plastic bearing surface. The deep surface of the knee cap is also often replaced. The soft tissues around the knee are not replaced.

The four parts that make up a total knee replacement
TKR benefits patients with arthritis of the knee joint who have failed non surgical treatment. The most common types of knee arthritis are osteoarthritis and post traumatic arthritis. The main indication for a knee replacement is pain.
There are no absolute age restrictions for knee replacement however it is usually not recommended for those under 60 unless symptoms are extreme. The reason for delaying knee replacement surgery to older age is that the knee replacement has a limited life span.
Patients must be fit enough to undergo a major operation while active infection precludes a knee replacement.
A - A normal knee with a smooth joint surface
B - An arthritic knee with wear of the joint lining

The total knee replacement in position
The first three months are hard work, with physiotherapy input to regain knee motion and strength. By three months two thirds of working patients have returned to some level of work. Typically patients are much better by 4 months after surgery. Full recovery takes 12 months.
Approximately 8 out of 10 patients who have a knee replacement are satisfied.
All operations carry some risk. Knee replacement is a safe operation but occasionally complications occur.
Risks common to all operations include:
Risks particular to total knee replacement include:
Research shows that satisfaction after knee replacement is most closely linked to patient expectation. Julian likes to ensure his patients clearly understand what to expect from their new knee. He provides a lot of resource material to his patients before their knee replacement. Setting realistic expectations of what the surgery can achieve results in a better outcome for his patients.
Julian performs computer navigated knee replacements. This technology allows very accurate alignment of the new joint. The hope is that this will result in better outcomes and longevity for the replaced knee. Julian has been navigating knees for over seven years and has considerable experience with this technique. He is a regular attender at navigation user group meetings nationally. He is delighted to have introduced this technique to Taranaki for his patients benefit.
Julian keeps a detailed database of his patients outcomes so a baseline is established for assessing the long term performance of the replaced joint.
Currently Julian is involved in helping set up an international project on new knee wound dressings. These dressings appear to reduce post operative inflammation and bruising.
If you think you may need a total knee replacement please arrange a consultation with Julian Stoddart. You will receive a comprehensive assessment of your knee to determine if this operation is right for you.
