Knee replacement, which is also known as arthroplasty, is a complicated surgical procedure to replace the damaged knee joint with artificial knee joints of metal and plastic. You may need to undergo knee replacement surgery if you have:
- Severe, chronic knee pain that refrains you from performing daily activities and disturbs your sleep.
- Swollen and stiff knee joint that you can’t even sit or stand properly.
A knee replacement lets you live an active life with little to no pain. It is recommended when all other treatments fail, such as physiotherapy, steroid injections, etc.
There are four main types of knee replacement surgery available. Depending on the patient’s condition, they are:
- Total knee replacement: It involves the replacement of the joint surface at the end of your thigh bone and the top of your shinbone. If required, it also includes replacing the under-surface of your knee cap.
- Unicompartmental partial knee replacement: If osteoarthritis has affected parts of your knee, mostly the inner side, then partial knee replacement is conducted.
- Kneecap replacement, also known as patellofemoral arthroplasty: Involves the replacement of the kneecap and its groove.
- Revision or complex knee replacement: There are many reasons responsible for revised knee replacement. It is mainly second or third time replacement when the first time surgery fails due to severe arthritis, loosened implanted device, etc.
Although there are various health conditions responsible for the knee replacement; however, some of the major causes are:
- Health conditions like knee osteoarthritis, rheumatoid arthritis, severe knee injury.
- Severe pain even while resting.
- Chronic knee inflammation that remains unaffected with physiotherapy, steroids, etc.
- Knee deformity
- Stiff knee that stops from doing usual activities like walking, sitting, standing, climbing stairs, etc.
Like any other surgery, there are chances of developing risks in knee replacement as well and they are:
- Wound infection
- Bone fracture/dislocation
- Infection of the joint replacement which may lead to another surgery
- Formation of blood clots in the deep veins in the leg
- Artery, ligament or nerve damage around the knee joint
- Persistent pain in the knee
Apart from these, you may react to anaesthesia which is rare. However, these rare complications may develop according to your age and current health state that you need to discuss with your specialist.
As knee replacement is a surgical treatment, therefore, it has several benefits related to it and they are:
- Increased mobility
- Little to no pain
- Back to usual lifestyle
It has been concluded that people who undergo knee replacement surgery are quite happy with the results and associated benefits.
As knee replacement is major surgery, it takes up to six weeks to resume a healthy, usual life. It takes six months to a year to fully recover from a knee replacement and lead a healthy life.
