If you are younger than 65 years and need a custom fit knee replacement Chennai, this article will be of interest to you.
Currently increasing number of young patients request a knee replacement. Surgeons offer smart tools to lower the risk of failure. One such method is ‘patient specific instrumentation‘ or custom fit knee. Dr.Venkatachalam was the first surgeon to introduce the Oxinium knee in Chennai. Now in combination with the Patient specific instruments, the Oxinium ‘Verilast’ knee can survive for a very long time.
The ‘Visionaire’, patient specific instruments is from Smith & Nephew, an implant company.
The ‘Visionaire’ patient specific instrument technology provides the surgeon a customized cutting jig tailor made to the individual patient’s anatomy. Patient’s anatomic data is collected from pre-operative x rays and MRI scans. The images are sent online to the company’s engineers based in the US through online software. An engineer uses this data to design and build customized surgical instruments that accommodate the unique shapes and angles of each patient’s joint for a more precisely aligned implant. These customized molds or cutting blocks are shipped to the surgeon within four weeks. Armed with these customized cutting blocks, the surgeon is confident of shaping the patient’s bone very accurately.
Benefits of Custom made knee instruments
Benefits of Patient Specific Surgery (custom made knee replacements)
A study published in The Journal of Arthroplasty concluded that surgeries using patient-matched instruments give results that were a full degree closer to neutral to the body’s natural alignment, than those which used traditional instruments. Accurate placement of an implant has long been considered and shown to reduce implant wear and improve longevity.
In addition to improving alignment, the Journal study concluded that patient-matched implant technology
- Reduces operation time
- Shortens hospital stay.
- Reduces the length of the surgical incision
- Minimizes blood loss.
- Lowers the risk of infection
With this combined technology, the implants can be expected to last for thirty years versus the ten to fifteen years with traditional cobalt chrome implants.
Utilizing patient specific instrumentation during the operation, the surgeon is able to make anatomically precise cuts of the knee bone for a customized fit of the prosthesis. The implant is thus aligned to fit the specific patient’s knee anatomy precisely. Reduction of pain and increased mobility and range of motion are just a few of the added benefits of such stability.
The Oxinium™ implant with ‘Visionaire’ patient specific instruments, offers minimally invasive procedures that reduce the risk of bleeding, complications, infections and postoperative pain. Patients are able to return to an active lifestyle faster than with traditional total knee replacement procedures, enhancing healing, mobility, and range of motion.
