MYTHS ABOUT MICROPLASTY
(PARTIAL KNEE REPLACEMENT)
MYTH 1: IT IS A STOP GAP SOLUTION
Partial knee implants last as long as Total knee replacements which is in the range of 20-25years depending on the age and activity of the individual. It is NOT AN INTERMEDIATE step before undergoing a Total Knee Replacement.
MYTH 2: LATERAL COMPARTMENT ARTHRITIS MAY DEVELOP LATER ON
The more commonly damaged Medial compartment(inner) of the knee is replaced and many patients have a fear that the Lateral(outer) compartment will eventually degenerate as well. In fact, after a Partial knee replacement the stress on the Lateral compartment is reduced drastically as the Knee is balanced accurately. The other logical thing is that if the Lateral compartment was well preserved for 50-60 years than the likelihood of it being damaged now with a well supporting Medial compartment is very less.
MYTH 3: WHY NOT REPLACE THE ENTIRE KNEE?
Some patients feel that why not replace the entire knee when they are anyways undergoing a surgery. The benefits of undergoing a Partial knee replacement are manifolds. Preserving the healthy bone and ligaments gives a much more ‘NATURAL FEEL’ to the knee and ensures a much faster recovery. The chances of complications like infection, thrombosis etc. are also much less in this procedure.
MYTH 4: Microplasty is a New Untested Technology
Unlike Robotics and 3D technology, Partial knee Replacement has been performed since 1970’s. The bearing has been so successful that it has not been changed even once! Even in India this surgery has been regularly performed in Mumbai, Bangalore and Delhi since the last 15 years.
MICROPLASTY requires a high level of skill and training and hence is not performed by all Joint Replacement surgeons.
Finally, God forbid but if a revision surgery is required than revising a Partial Knee Replacement is much easier than a Total Knee replacement.
