 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 
which includes: -
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 joint’s 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.
