Total Knee Replacement and 3D Technology India - Kne3wiz

Best Technology for knee replacement in India. Total Knee Replacement and 3D Technology India, Performed using an advanced system with highly specialized software, infrared camera, and trackers. Knee replacement surgery is state of the art facilities, equipped with state of art infrastructure and latest technology.

During surgery, trackers are temporarily attached to the patient’s knee bones which transmit data to the infrared camera. This data is processed by the computer to provide real-time 3D information about the patient’s knee joint and leg alignment. The surgeon uses this information to plan bone cuts, adjust soft tissue tension, customize implant position and insert the artificial knee joint accurately.

Precise implant positioning is likely to reduce joint wear, and improve the lifespan of the artificial joint. This technology also forms an important part of robotic knee replacement. The reported benefits of computer-navigated Knee Replacement include better alignment, 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 swell aiding early mobilization and recovery.

Augmented Reality for Assistance of Total Knee Replacement - Kne3wiz

The aim of this work was the development of a surgical assistance system based on augmented reality to support joint Augmented Reality for Assistance of Total Knee Replacement procedures and implantation of the prosthetic knee. Images of the scene were captured in order to detect the visual markers located on the lateral surface of the patient’s leg for overlapping the 3D models of the prosthesis and the joint, as well as the tool used by the medical specialist. With the marker identification, it was possible to compute its position and orientation for locating the virtual models, obtaining a monitoring system for giving accurate information about the procedure.

Assisted computer surgery has improved the accuracy of many types of medical procedures, such as laparoscopy where the surgeon manipulates robotic arms performing minimally invasive surgery, using machine vision algorithms to obtain relevant data of the operation area during surgery.   

It is important to mention that due to the machine vision technique is possible to perform surgical procedures based on augmented reality, as can be seen in, where they use image processing for locating virtual tools and 3D models of some organs as well as the incisions, fastenings, and sutures necessary for performing the surgery, showing new fields in medical training without real patients.

One of the works that use the above concepts is presented in, focused on pancreatic surgery by using 3D modeling to represent the pancreas and an adjacent tumor, which is monitored by the surgeon during the intervention with some limitations in the real-time processing; however, the impact and importance of this technology in future surgeries and medical training are highlighted.

Latest Advances in knee Replacement Surgical Technique - Kne3wiz

Total knee replacement technology. Bets 3D augmented surgery with computer assisted knee replacement technique. Latest knee replacement surgery technology involves a very complex set of measurements and angles. If an implant is misaligned or positioned incorrectly, it is more likely to function poorly and the patient may suffer from uneven or successive wear.

For years, orthopaedic surgeons would conduct the complex set of measurements and angles DURING the initial phase of surgery.

Recent technological advances in biomedical engineering software have opened a new chapter on high-performance knee implants.

    Today, we utilize “cutting guides” that are patient-specific, single-use instruments that guide me as I shape the ends of the bones to fit the new implant.
    
    What makes these guides so special is that each one is specifically designed using computer-simulated 3D model of the patient’s own knee. It is then custom built to be used in THAT patient’s surgery.
    
    The process for making the (Visionaire) cutting guides starts with the patient getting a short MRI scan of the knee and a full-length x-ray of the leg (during pre-op visits).
    
    The information from these images is then fed into a software program used by an engineer to build a virtual model of your knee and (the engineer) will send me a pre-op plan detailing the patient’s specific anatomy.
    
    During my pre-surgical planning, I can use the virtual model to easily select the right size implant for the patient AND pre-operatively determine what angle bone cuts I need to make and exactly how much bone I need to remove to insure that patient’s implant is place in the optimal alignment, all before the patient ever reaches the operating room.

Computer-assisted total knee replacement is a procedure that utilizes sophisticated computer imaging to assure the highest level of precision during the total knee replacement surgery in Ahmedabad. With the aid of a real time infrared based tracking system, we can achieve virtually perfect alignment and soft tissue balance, which are the two most critical components of a successful knee replacement.

In some ways, computer-assisted surgery is similar to the commonly used GPS systems found in aircraft and automobiles. Both systems localize specific positions in space in relation to their surroundings. Where the GPS system uses satellites and the concept of triangulation to locate positions, the surgical navigation system uses an advanced stereotactic camera and an infrared light source to locate points in space. The sophisticated software system used during surgery measures the position of your bones and the surgeon's instruments in relation to each other simultaneously at all times throughout the procedure.

Over the last decade it has become increasingly clear that using conventional methods of hand held rods and jigs to guide positioning of knee replacement components during surgery lacks in accuracy and doesn't allow the surgeon to align the knee correctly in a consistent and reproducible fashion in a high enough percentage of cases. In addition to this, placing rods into the tibia and femoral bone has the added down side of increase pain, blood loss and introducing fat emboli into the blood stream, all which are associated with less than ideal outcome for the patient.

To address these deficiencies, two new methods were introduced: one involves using special infra-red positioning sensors and a computer that work together to assist the surgeon during the operation to accurately perform the bony cuts, forgoing the need for traditional hand held rods and jigs. This first method is often referred to as “computer assisted surgery” (CAS). The computer allows us to accurately cut the correct amount of bone off both the tibia and femur in exactly the right angles to achieve the perfect fit and balance for each patient. This method has consistently been shown to be accurate in a number scientific studies.

A System dedicated to ensuring to perfect fit and position of knee implants, kne3wiz employs 3D capabilities to develop 3D bone models which offers unmatched precision while planning as well as operating. Thinking one step ahead, can we make something which will help to reduce the load of inventory and instruments? Can we create something which help us to give accurate sizing before start the procedure.? Can we design something which reduces the few trays of instruments in just on device?

Kne3wiz best technology for knee replacement surgery for hip Replacement Surgery, latest knee replacement surgery Ahmedabad, 3d augmented knee replacement Gujarat, hip Replacement Surgeon in Ahmedabad, Top 10 Hospitals for Knee Replacement, Knee Replacement in Ahmedabad, Revision Knee Replacement, Joint Replacement in Gujarat.

Today, most of the companies are facing the challenges in logistics/inventory to make available all size implants during the surgery because of their different sizing option. The companies are spending Millions of dollars in instrument part. There are huge numbers of instruments / tray for cutting and measurement of sizing etc. These instruments can help to gain accurate surgical output. Few are best to use and precise like Attune Intuition Instrument System.

Kne3wiz is a 3D imaging based total knee instrumentation system. It helps to customize the implants. This invention helps to give Accurate 3D Dimensions X, Y, Z Axis, and most important it gives you the perfect size of the implant before you measure the sizes during the live surgery.
