Knee replacement
Knee replacement, also known as knee
arthroplasty, is a surgical procedure to replace
the weight- bearing surfaces of the knee joint to
relieve pain and disability. It is most commonly
performed for osteoarthritis, and also for other
knee diseases such as rheumatoid arthritis and
psoriatic arthritis.
Risk in surgery -
Knee replacement surgery, like any surgery,
carries risks. They include

• Infection
• Blood clots in the leg vein or lungs
• Heart attack
• Stroke
• Nerve damage

The replacement knee joint may become loose, be
dislodged, or may not work the way it was
intended. The joint may have to be replaced again
in the future.
Nerves or blood vessels in the area of surgery
may be injured, resulting in weakness or
numbness. The joint pain may not be relieved by
surgery.
There are different types of knee replacement

Total knee replacement- The replacement knee
joint may become loose, be dislodged, or may not
work the way it was intended. The joint may have
to be replaced again in the future.Nerves or
blood vessels in the area of surgery may be
injured, resulting in weakness.

Partial knee replacement  only affected part of
knee is been replaced.
Bilateral knee replacement - both the knees are
replaced at same time.
During surgery -
During the procedure, the surgeon will remove
bone and diseased cartilage from where your thigh
bone (femur) and shin bone (tibia) meet at your
knee joint.
Those surfaces are then replaced with a metal
implant. A piece of special plastic is normally
used to replace the backside of the kneecap and
finally, this same plastic material is placed in
between the two metal parts.
This gives both bones of your knee joint smooth
surfaces again so they can flex and bend more
freely and painlessly.

Parts of knee -
The knee consists of the following

1. Tibia. This is the shin bone or larger bone of
   the lower leg.
2. Femur. This is the thighbone or upper leg bone.
3. Patella. This is the kneecap.
4. Cartilage. A type of tissue that covers the
   surface of a bone at a joint. Cartilage helps
   reduce the friction of movement within a joint.
5. Synovial membrane. A tissue that lines the joint
   and seals it into a joint capsule. The synovial
   membrane secretes synovial fluid (a clear, sticky
   fluid) around the joint to lubricate it.
6. Ligament. A type of tough, elastic connective
   tissue that surrounds the joint to give support
   and limits the joints movement.
7. Tendon. A type of tough connective tissue that
   connects muscles to bones and helps to control
   movement of the joint.
8. Meniscus. A curved part of cartilage in the knees
   and other joints that acts as a shock absorber,
   increases contact area, and deepens the knee
   joint.
