Ageing, Arthritis, Joint infection may be the results of aching knees. They heavily impact the quality of life and restrict the range of motion. If your knee is severely damaged by arthritis or injury, it may be hard for you to perform simple activities, such as walking or climbing stairs. You may even begin to feel pain while you are sitting or lying down. A knee replacement (also called knee arthroplasty) might be more accurately termed a knee ``resurfacing`` because only the surface of the bones is replaced.
The most common reason for knee replacement surgery is to relieve severe pain caused by osteoarthritis. People who need knee replacement surgery usually have problems walking, climbing stairs, and getting in and out of chairs. Some also have knee pain at rest. In determining whether a knee replacement is right for you, an orthopaedic surgeon assesses your knee’s range of motion, stability and strength. X-rays help determine the extent of the damage. Your doctor can choose from a variety of knee replacement prostheses and surgical techniques, considering your age, weight, activity level, knee size and shape, and overall health.
The knee is the largest joint in the body and having healthy knees is required to perform most everyday activities. One can experience knee pain due to several reasons:
- Osteoarthritis: There is “wear-and-tear” of knee joint as one ages. It is a kind of degenerative disorder where there is an age related type of arthritis. The bones then rub against one another, due to the wearing away of cartilage, causing knee pain and stiffness. Young people also experience severe joint pain and known to have arthritis termed as “Juvenile Arthritis”
- Rheumatoid Arthritis: Rheumatoid arthritis is the most common form of a group of disorders termed “inflammatory arthritis.” It is a condition in which synovial membrane of the joint becomes inflamed. This can cause the cartilage to cause intense pain and stiffness.
- Post-traumatic Arthritis: Traumas are a major cause of Post-traumatic Arthritis. It can be following a serious knee injury or trauma to the joint. Fractures, if any, may damage the articular cartilage causing knee pain and limiting range of motion.
When does one require Total Knee Replacement Surgery?
It is recommended to take the decision of having a knee replacement surgery co-operatively, after discussing it with your family, friends, your doctor and your orthopaedic surgeon. Your orthopaedic surgeon must evaluate you thoroughly before deciding of having a surgery.
It is recommended to have a surgery if you have chronic-unbearable knee pain or stiffness that limits you from performing daily activities including walking, climbing or even standing. Or, if you are experiencing chronic knee inflammation and swelling that does not improve with rest or NSAIDs. Knee Deformity can also be a reason to perform knee replacement surgery. Recommendations for surgery are based on a patient’s pain and disability, not age. Most patients who undergo total knee replacement are age 50 to 80, but orthopaedic surgeons evaluate patients individually. Total knee replacements have been performed successfully at all ages, from the young teenager with juvenile arthritis to the elderly patient with degenerative arthritis.

Types of Knee Replacement Surgeries performed in India?
One can opt for knee replacement surgery based on their medical condition and according to the suggestion of their orthopaedic surgeon.
Total Knee Replacement: It is recommended when all the non-surgical treatment options fail. Total knee replacement surgery is done to replace the damaged surface with an artificial implant through a 7-8” incision around the joint. Post-operative therapy for the patient is a must to get accustomed to the artificial implant.
Partial Knee Replacement: It is also known as uni-compartmental knee replacement; it replaces the parts of the knee joint which are severely damaged with artificial implants.
Minimally Invasive Knee Replacement: It makes use of surgical methods to make a small 5-7” incision in order to insert the implants. It does not cause any damage to the neighbouring quadriceps muscles hence it is called Quadriceps Sparing Knee Replacement Surgery.
Hi-flex knee replacement: It allows a candidate to flex their full knee upto 155 degrees. However, not every patient can be a candidate for Hi-flex knee Replacement Surgery. This degree of high flexion is attained only by selecting the right patient, implant design, surgical technique and aggressive rehabilitation post-surgery.
Computer navigated knee replacement: As the name suggests the surgery is performed with the highest level of precision with the skilled hand of an orthopaedic surgeon. With the most advanced and revolutionary navigation technology the surgeon can accurately implant the prosthetic with minimum scarring.
