Knee Replacement Surgery

Present day India has a population of 1.37 billion people, and out of those people a significant number are afflicted with arthritis of the knee. Studies state more than 120,000 knee replacement procedures take place in India annually and the numbers are gradually increasing, and so is people’s trust in the success of the surgery. The first total knee replacement was done in 1968. Since then, there have been ground breaking improvements in the methodology and surgical implants, this in turn has augmented the efficacy of the procedure.

What is Robotics in Knee Replacement?

Total knee replacement is one of the most successful surgical procedures of all times. It is reliable, proven treatment for lessening the pain and achieving functional recovery of the knees in end stage arthritis, giving more than satisfactory outcomes in more than 90% of the patients.

In contemporary times robotic surgery has been increasingly chosen as an option to address human error. The use of robots has proved to reduce the human errors made when placing and moving the surgical tools.

These robots aid with preoperative imaging, planning, registration and cutting. Mechanical alignment, implant position and soft tissue balance play important role in the success of treatment. It is extremely important to place the implant in near perfect alignment. Precise implant positioning reduces wear and tear of the joints, and augments the life of the implant. In conventional technique, only 70% - 80% of the cases would obtain ideal positioning of the prosthesis.

We, at Aakash Healthcare Super Speciality Hospital use the NAVIO Robotics, which is designed to deliver consistent and accurate results through the utilization of a surgeon-controlled robotics-assisted hand piece, coupled with NAVIO specific cut guides. This unique combination yields an intuitive and efficient workflow for the entire surgical team.  

In addition, the versatile NAVIO planning software enables precise implant alignment and ligament balance, without the need for a pre-operative CT scan.  Eliminating the dependency on pre-operative imaging allows the surgeon to seamlessly plan for either a partial or total knee procedure at the time of surgery.

What are the benefits of Robotic Knee Replacement?

The reported benefits of computer navigated TKR include better component positioning, improved patient satisfaction, superior clinical outcomes, lesser blood loss and lower blood transfusion rates. It also results in lesser post-operative inflammation which may reduce pain and swelling aiding early mobilization and recovery.

Use of robotics in knee surgery is a very recent advancement. I am sure it is soon going to be an indispensable tool to achieve near perfect and long-lasting results.


What is Conventional Knee Replacement?

Knee replacement is a surgical technique where a manufactured substitute for the cartilage/ deformed joints is embedded on the end of the bones. The surgery consists of replacing the diseased or damaged joint surfaces of the knee with metal and plastic components that are shaped to allow continuous motion of the knee. The recovery time frame might be 6 weeks or less and may involve the use of mobility aids (e.g. walking frames, canes, crutches) to enable the patient's return to preoperative mobility. 

Likewise, on the off chance if you need to go for both knee replacements at the same time, it would reduce cost, rehabilitation and recovery time. 

What causes knee joint degeneration?

Mechanical "wear and tear" on a person's knees over a lifetime seems to be an obvious explanation for the increase of arthritis with age, but the answer is not that simple. The current view is that a number of factors act together to cause knee deterioration. Some of these factors include heredity, developmental abnormalities of knee formation, genetic tendency to abnormal cartilage metabolism, major or minor repetitive injuries, and certain occupations. While being overweight does not necessarily cause arthritis, it certainly contributes to early and more rapid development of knee problems.

Who is a candidate for knee replacement surgery?

People with painful knee deformities, severe degenerative X-ray changes, or advanced symptoms of arthritis are candidates for knee replacement surgery. Symptoms of advanced end-stage knee arthritis include:

Pain persists over time




Muscle weakness

You’re no longer as mobile as you used to be 



Our Specialty 

At our centre, we perform minimally invasive total knee replacement. We use advance technology, which reduces chances for any infection, enables faster recovery and less blood loss. 

How Long Does the Replacement Last?

Studies have shown that more than 80 to 85 percent of patients still have a functioning implant, even after 20 years of replacement. However, few advance methods may last up to 30 years. 

Pain Post Surgery

For the most part, individuals have this dread that they will encounter extraordinary pain after the surgery. At our centre pain management is our top priority. We have a dedicated team for pain management, who use sophisticated methods like spinal epidural catheters, patient controlled anaesthesia, regional blocks, transdermal patches to keep you virtually pain free in post-operative period.
