Hard cartilage helps to cover thigh and shin bones and allows the movement of bones. Arthritis is a chronic disease which damages the hard cartilage, making it thinner. Because of it, the bones rub against each other and become worn. In knee replacement surgery, the hard cartilage as well as the worn out ends of the bones are removed. In their place, the metal and plastic parts are fixed. The plastic parts act as hard cartilage, thus providing free joint movement. This artificial joint permits your knee to bend, thus offering more flexibility.

Types of knee replacement surgery:
There are two main types of surgery, depending on the condition of the knee:
- Total knee replacement (TKR) – Both sides of your knee joint are replaced
- Partial (half) knee replacement (PKR) – Only one side of your joint is replaced in a smaller operation with a shorter hospital stay and recovery period
Why is the knee replacement surgery needed?
The most common reason for knee replacement surgery is osteoarthritis. Other conditions that cause knee damage include:
- Rheumatoid arthritis
- Knee injury
A knee replacement is major surgery, so is normally only recommended if other treatments, such as physiotherapy or steroid injections, haven’t helped reduce pain or improve mobility. One may be offered knee replacement surgery if:
- One has severe pain, swelling and stiffness in knee joint and his/her mobility is reduced
- One`s knee pain is so severe that it interferes with his/her quality of life and sleep
- Everyday tasks, such as shopping or getting out of the bath, are not easy or impossible
- One`s cannot work or has a normal social life
Are there any risks?
This surgery is a common operation and most people do not experience complications. However, as with any operation, there are risks as well as benefits. Complications are rare but can include:
- Stiffness of the knee
- Infection of the wound
- Deep infection of the joint replacement, needing further surgery
- Unexpected bleeding into the knee joint
- Ligament, artery or nerve damage in the area around the knee joint
- Blood clots or deep vein thrombosis (DVT)
