Dr. Shekhar Srivastav is a senior orthopaedic consultant and Robotic Knee Replacement Surgeon performing Joint Replacement and Arthroscopic Surgeries of Knee and Shoulder Joints and is HOD of the Orthopedics Department Delhi Institute of Trauma and Orthopaedics (DITO), Sant Parmanand Hospital. He has a keen interest in management of Knee and Shoulder problems, Robotic Knee Replacement Surgery.
He has performed thousands of Total and Partial Knee Replacement (Primary, Revision & Unicondylar replacement) and Arthroscopic Surgeries ( ACL, Meniscus, Cartilage surgeries). Similarly in shoulder, he’s an expert in performing shoulder Arthroscopies (Bankart repair, Rotator Cuff Repair) and Shoulder replacement Surgeries (Total & Reverse Shoulder Replacements).
Robot-assisted Knee Joint Replacement Surgery
The procedure for a Total knee Replacement (TKR) has advanced greatly with the development of new materials and the increasing understanding of the knee joint biomechanics. An accurate alignment of the component and soft tissue balancing has been cited as the essential for the success of Total knee Joint Replacement (TKR). Although mechanical alignment guides have been designed to improve alignment accuracy, there are several fundamental limitations of this technology that will inhibit additional improvements.
There are limits on improving the alignment accuracy using a conventional total knee replacement. Computer-assisted surgery (CAS) was introduced to overcome the difficulties and errors. Computer-assisted total knee Replacement has gained increasing acceptance among orthopedic surgeons as a technique to improve surgical precision and patient outcomes.
The Joint Replacement surgical robotic system is the most advanced surgical equipment capable of 3D pre-planning, virtual surgery and precise cutting to provide accurate and precise surgery results.
With the advent of Robotic technology in TKR surgeries the limitations have been drastically mitigated with 3D CT pre-planning, Accuracy and predictability in surgical outcome.
What is Robotic Knee Joint Replacement Surgery?
In knee replacement surgery, the arthritic portion of the knee is removed and replaced by an artificial joint that form the new surfaces of the knee joint. During Robot assisted total knee replacement, Robotic Knee Replacement Surgeon uses computed tomography (CT) scans to build a 3D model of the patient’s knee. With that virtual model as guide, the surgeon then uses the robotic arm to make accurate bone cuts and insert the knee components precisely.
Types of Robotic Technology
Well when we speak about Robotics, it indeed has to be smart and must be easily maneuvered. Knee Replacement, being the prominent amongst all other joint replacement surgeries, had the privilege of getting more attention from researchers and technologists. If we are to differentiate currently available knee replacement robotic systems, they are briefly classified as passive, semi-active and active systems. The major factor which has led to this differentiation is the nature of work robotic system does with least human interference. Passive and Semi Active type system guide the surgeon through the fixation and cutting block resection stages – the actual cutting and drilling processes are executed by the surgeon. Active robotic joint replacement systems which are said to be the most advanced amongst its peers are completely autonomous in nature with least human interference required.
