1. MINIMALLY INVASIVE KNEE
REPLACEMENT
MIS as an alternative to knee replacement surgery

2.  A surgical procedure done
to replace the weight
bearing areas of the knee
by invading the knee in
minimally invasive manner
through a 2 to 3 inch
incision, with less cutting
of skin.
 The damaged part of knee
is taken out and an
artificial prosthesis is
placed inside.

3. This method is a great
alternative to knee
surgery for patients with
arthritis or other
disabilities due to its
advantage of using
modern biomaterials and
making smaller incisions
when compared to total
knee replacement.

4. What makes minimally invasive
knee surgery more useful?
As the name suggests, the cut made is only
2 to 3 inches which spares surrounding soft
tissues from surgical trauma and further
damage
The artificial implants are designed in such
a manner that they align themselves to give
more mobility and range of motion

5. Surgical Equipment
The surgical
equipment's are
improved
guidance through by
robotics
computer navigation
Expert surgeons

6. MIS offers
 Minimum need for the patient to stay in the hospital
 Speedy recovery
 The procedure is sometimes performed on
outpatient department
 The treatment is carried with least possible
damage to the body
 Risks of infections are reduced

7. Results
MIS gives better results
when it comes to
 movement
 walking
 climbing stairs and
 other chores of daily
routine

8. When is MIS indicated?
 MIS can be chosen as an
alternative to knee surgery
if the patients suffer from
advanced osteoarthritis
after 50 years of age, with
or without deformity.
 MIS is good as a choice

9. In cases of excruciating pain, where other
conservative methods like medicines or
physical therapy have failed to give any
relief
Apart from this, the surgeon may also
suggest the same when patient finds
difficulty in everyday activities like using
toilet, kneeling, forward bending or walking.

10. How is minimally invasive surgery
performed?
Orthopedic surgeon performs a physical
examination including
 Range of motion testing
 X-ray
 Patients complete medical history and
 Discussing alternatives with the patient about
minimally invasive surgery.
The aim of MIS is to provide more stability and early
recovery to the knee joint.

11. The procedure is done by making a small incision in the
quadriceps muscle tendon. Quadriceps aides in standing,
walking, knee straightening etc. Therefore the procedure
also preserves the function of this muscle. After the knee
joint is exposed, the knee cap is simply pushed aside
unlike traditional surgery when the knee cap was turned
over. The damaged areas are scraped, removed and the
modern prosthesis is placed inside.

12. What are the side effects of MIS?
 The common side effect is dislodgement of a clot
from leg veins to the arteries of heart or lungs and
producing severe complications and even death.
This can be taken care by wearing a compression
stocking.
 A poor implant size with large or thin spacers can
also make adjustment of prosthesis difficult as they
would not match the size of the joint. Not only this,
the implant may loosen from its original position
due to an accident, fracture, osteoporosis and in
advanced rheumatoid arthritis.

13.  A common complication may arise when exercises are
not started in time and patient suffers with knee stiffness
or limited bending of the knee.
 This often results when there is scarring or formation of
thick adhesions in the joint cavity. There could also be
chances of infection precipitating in a few days after
surgery if it is not done sterile conditions.
