Reasons for your procedure
Knee replacement surgery is a treatment for pain and disability in the knee. The most common condition that results in the need for knee replacement surgery is osteoarthritis. Osteoarthritis is characterized by the breakdown of joint cartilage. Â
Damage to the cartilage and bones limits movement and may lead to pain. Individuals with severe degenerative joint disease may be not able to do normal activities that involve bending at the knee, like walking or climbing stairs, as they're painful. The knee will swell or "give-way" since the joint isn't stable. If you are suffering from any of the above-mentioned symptoms, you can visit Ujala Cygnus hospital. It is one of the  best hospital in Varanasi for knee replacement.
Other types of arthritis, such as rheumatoid arthritis and arthritis that results from a knee injury, can also result in degeneration of the knee joint. Additionally, fractures, torn cartilage, or ripped ligaments can cause irreversible damage to the knee joint.
