What is Total Knee Replacement?
Total Knee Replacement is a surgical procedure wherein diseased knee is treated by removing the damaged cartilage and bone and replacing it with a synthetic one.
The materials used to create an artificial joint are made up of metal (titanium or cobalt chrome) and are strong and long-lasting.
Since they produce less friction, they are optimal for joint function.
What is the cause of knee joint disintegration?
One of the major reasons that affect the knee joint and hinder routine activities is Arthritis.
The slowly wearing condition of the tissue on the ends of the bones leads to a reduction of joint space, severe joint pain, regular shifts in bone movement, and friction in the exposed bone surface.
There are three types of arthritis:
Osteoarthritis occurs from ‘wear and tear’ and is the most common reason for the total knee replacement.
It usually occurs after the age of 50 and is a genetic problem.
When the tissue covering the bones softens and wears away, the bone began to rub against each other and leads to severe pain.
When the tissues surrounding the bone releases excessive fluid due to inflammation, it causes damage to cartilage and other parts of the joint and causes pain and stiffness.
This type of arthritis usually occurs after a serious knee injury.
Due to the knee fracture, the connective tissue and the tissue covering the ends of the bone wears away, resulting in pain and stiffness.
Who is the ideal candidate For Knee Replacement?
If a person experiences daily pain that hinders work, recreation, and daily activities of routine life, he/ she may be considered for a total knee replacement.
Most people undergo knee replacement after the age of 50, but sometimes the knee replacement is also considered by a younger lot if their knee condition is severely affected.
- Complete history and physical examination of the candidate
- X-ray examination to assess the total amount of damage caused
- Blood tests are also >done to prevent inflammatory arthritis
Types of Knee Replacement
There are four types of Knee Replacement procedures:
Partial Knee Replacement
It is a minimally invasive procedure wherein a single part of the affected is removed and replaced with the metal implant.
It is also known as unicompartmental knee arthroplasty and most often considered for patients suffering from Osteoarthritis.
Rotating Knee Replacement
With the Rotating Knee Replacement, the metal implant installed not only move back and forth but can also rotate inwards and outwards.
This procedure has been designed to replicate the rotating motion of a normal knee joint.
Gender-Specific Knee Replacement
It is a special technique of knee replacement wherein the implants are designed similarly for both men and women, but their average differs.
The concept behind this procedure is that if implant properly imitates the normal anatomy, it will allow better function and better stability.
Custom Knee Replacement
It is another type of knee replacement procedure wherein MRI is taken first, and customized incision guides are prepared for the patient.
It enables the surgeon to do precise removal and replacement of the knee joint.
Oxinium Total Knee Replacement

Owing to their high activity levels, most conventional knee implants last only for 10 to 15 years. Oxinium knee implants offer the durability of 30 to 35 years at a stretch.
These implants are designed of metal composites made up of ceramic and coated with oxygen which made them extremely durable and long-lasting.
Benefits and Postoperative care
The advantages of Total Knee Replacement are pain relief, improved mobility, and improved quality of life.
