One of the main reasons for knee replacement
surgery becoming one of the most successful
surgeries is the continuous development of knee
implants with different materials that improve
the longevity of the knee implant. What makes an
ideal knee implant? An ideal knee implant must
last for more than 15-20 years, should allow for
regular activities and knee motion. It must
perfectly fit the requirement of the patient that
a knee replacement surgeon is aiming for and also
must be congruent with the patients allergic
conditions. As result, there are a variety of
implants that are available in the market which
are made up of different materials. If you are
looking for more information on implants used in
knee replacement surgery then this blog is for
you. Here we discuss four types of knee implants
commonly used by knee replacement surgeons in

Types of knee implants used in a knee replacement
surgery A whole knee joint implant is primarily
made up of 3 components. A femoral component that
is attached to the resurfaced thigh bone, a
tibial component that is affixed to the prepared
shin bone, a plastic spacer that is placed
between them and a patellofemoral component that
replaces the natural knee cap. All types of
whole knee implants can be broadly classified
into four types based on the materials used for
the implants. They are as follows Metal-on-plast
ic  Most common type of knee implant that is
widely used in knee replacement surgeries is the
metal-on-plastic knee implant. It has the longest
successful track record as the most trusted knee
implant and also happens to be economical.

The femoral component that is made up of metal
rides on the plastic spacer fixed to the tibial
component of the shin bone. Nickel, zirconium,
titanium, cobalt-chromium are common types of
metals used in this implant. Ceramic-on-ceramic 
As the name suggests both the femoral and tibial
components are made up of ceramic material which
makes this implant hard to react with the insides
of the body. But as the ceramic material is not
as hard as plastic or metal they carry the risk
of breaking under high energy direct events
(rare). They are also prone to making a squeaking
sound in most cases. Ceramic-on-plastic The
metal used in common metal-on-plastic is replaced
with ceramic to make ceramic-on-plastic knee
implant. This implant is generally used by a knee
replacement surgeon if the patient is found to be
sensitive to the use of the metal in the
metal-on-plastic implants. Just like
metal-on-plastic, the plastic used for the spacer
may cause an immune reaction in certain patients.

Metal-on-metal implants Metal-on-metal implants
last longer than all other implants due to their
robust construction. So, they are naturally used
for younger patients. However, they pose the risk
of metal traces leaking into the bloodstream to
cause possible internal damage and hence they are
not that highly preferred by knee replacement
surgeons.  A knee implant is carefully chosen by
a knee replacement surgeon based on the surgery
and medical history of patient. If you are living
