Benefits of Custom Fit Knee Replacement Surgery

Fortis Hospitals , Bangalore Ushers In the Latest Technology in Knee Replacement Surgery, Conducts Asia’s First Custom Fit Knee Replacement Surgery in Bengaluru

Ushering in the latest in Joint Replacement Surgery Fortis Hospitals Bangalore today announced Asia’s first ‘Custom Fit Knee Replacement Surgery’ performed on two patients with degenerative disease of the knee. Lead orthopedic surgeon Dr. Sanjay Pai and his team at Fortis Hospitals Bangalore performed this revolutionary surgery by literally remodeling the anatomy of the patient’s knee and recreating or customizing a knee with the right kind of technology and expertise. The new custom fit knee replacement technology designs a perfect instrumentation system that matches the patient’s knee and ensures lesser pain, less tissue damage and faster mobilization.

Case Highlights

• A 56 and 59-year- old women suffering from degenerative disease of the knee
• Brought to Fortis Hospitals with complications, underwent Asia’s first Custom Fit Knee Replacement Surgery
• Patients were discharged within five days of the knee replacement operation
• Patients started walking normally within a fortnight unlike the usual 6-8 weeks required before starting normal activities in the conventional surgery.

Benefits of Custom Fit Knee Replacement Surgery

According to Dr. Sanjay Pai, Senior Orthopedic Surgeon, Fortis Hospitals “The two operations for knee replacement have been performed for the first time in Asia using the custom fit knee replacement technology. This is indeed a medical breakthrough and likely to revolutionize the way knee replacement surgeries are performed in India. We are glad to be the first adapters of this technology.”

Difference between conventional Knee Replacement and Customized Knee

While conventional knee replacement surgeries retro-fit predetermined sizes of prosthetics on to the patients’ knee, this procedure is very different because it works on the principle that no two patients’ knees are similar. With this technology the patient’s knee is digitally recreated with 3D image mapping after taking into account, the bone structure, weight ratios, gender, age and even mechanical alignment. Based on this 3D model the customized knee is created. Something, that just fits them right. This technology ensures far greater accuracy and reduces the operation time by almost 40 % and also results in less loss of bone & tissues.

Benefits of Customized Knee Replacement

Smaller incision
Less soft tissue damage
Lesser pain
Early and better mobilization
Better and pain free range of motion
Improves alignment and sizing by using computer generated images of the patients anatomy to determine bone cuts and implant positioning preoperatively

Faster Recoveries That Get Patients Back To Life Faster

Right from diagnosis, Fortis Custom Fit Knee Replacement procedure aims to get patients back on their feet faster. It takes about 4 week duration to get the custom fit instrumentation and the doctor being ready with the perfect procedure, the incision is just about 4inches which itself minimizes the pain, infection, blood loss, and tissue damage are also reduced to a great extent. And specialized post-operative recovery procedure ensures that the patient achieves early and full mobility within days after his/her surgery.

How Custom Fit Knee Works

4 weeks. That’s the time we take to find the knee procedure complete with the instrumentation that fits you perfectly as opposed to the trial and error that you need to endure in the conventional procedure. Fast and convenient, it is a simple 4 step process.

Step 1: Stages of Custom Fit Knee Replacement
The process starts with a CT Scan of the whole leg from the hips to the ankle which is then used to create an advanced 3D image of the leg structure. The age, weight and gender are also taken into account, creating a complete patient imaging.

Step 2: Processing and planning
With the 3D plan of the leg structure in place, an anatomical model is created to determine the mechanical alignment – the basic philosophy on which the entire process rests. Virtual instrumentation is then done and the surgery is planned accordingly.

Step 3: Recreating the knee
Once the surgery is approved, the Custom Fit instruments are manufactured at state-of-the-art dedicated manufacturing centers. Even the individual patient name and data are etched on each unit to confirm identification during the surgery

Step 4: Fitting the knee
With the Custom Fit instrumentation in place, the knee bone is chiseled to perfection so that the prosthetics fit exactly without any requirement for later corrective surgeries. After a 60 minute surgery, the patient ill have the knee that fits you perfectly.

Patient Case Details:
Mrs. Rukmini Thimmaiah, a 59-year-old woman, was diagnosed with osteoarthritis of right knee after pre-operative evaluation at Fortis Hospitals Bangalore. The custom fit knee replacement surgery was successfully performed on Rukmini by Dr Sanjai Pai, Senior Orthopedic Consultant and his team at Fortis Hospitals and the patient was discharged within five days.

After 14 days, the patient started walking independently, was able to sit and get up comfortably, climb stairs without any support and did not complain of any pain, swelling or discomfort around the right knee.
Mrs. Sujatha Venkatesh, a 56-year-old woman, had a similar problem in her left knee. She also successfully underwent the custom fit knee replacement surgery at Fortis Hospitals and was discharged within five days. Within a fortnight, Sujatha was also able to walk, sit and climb stairs normally like in the above case.
