Brief Summary

For the first time in Russia, it is planned to introduce and study primary knee arthroplasty using an active robotic system. The aim is to increase the efficiency of primary total knee arthroplasty using an active robotic surgical system. Traditional endoprosthetics of the knee joint (TKA) has now reached its maximum manufacturability and efficiency, but the accuracy of the performance depends on the skill and experience of the surgeon, as well as the efficiency of the cutting instrument (oscillator saw) when performing bone resection, the condition of the instrument and on the density of bone tissue fabric, which is highly variable. Modern RSS used in orthopedics include a robotic arm, robotic cutting devices with a computer navigation system, which are in active, semi-automatic or passive control mode. The main advantage of robotic systems is accurate preliminary planning using 3D modeling, use individual implant selection and virtual positioning.The active robotic surgical system TSolution-One allows participants to level the error in the positioning of the implant. The active robotic surgical system (ARSS) allows to correctly install the implant, which affects its service life, reduces the risks of postoperative complications, quickly returns to the usual way of life and forgets about the technical negative sensations and limitations that existed before the operation.It is planned to conduct an open-label retrospective and prospective clinical study in parallel observations.The study is planned to include 300 patients with osteoarthritis of the knee joint stage 3-4 (according to Kellgren-Lawrence). Investigators took three groups of patients, 100 patients each, and offered different options for total knee arthroplasty techniques.According to the research:-A clinical active robotic system for primary total knee arthroplasty will be introduced in Russia-There will be recommended indications and contraindications for this system in patients with gonarthrosis-The methodology of preoperative planning will be improved-The results of primary knee arthroplasty with an active robotic system will be evaluated in comparison with standard techniques and computer navigation-The methodology developed and improved in the dissertation will be introduced into the work of the clinical departments of traumatology, orthopedics and disaster surgery, studying the learning curve.

Detailed Description

Relevance: Robotic technologies were first introduced into medicine in the 1950s. The use of robotic systems in surgery begins with the use in neurosurgery. In 1985, the Programmable Universal Manipulation Arm (PUMA) 560 was introduced to perform CT-guided brain biopsy. In 1992, the Robodoc system (IBM) became the first orthopedic robotic system used in orthopedics for hip replacement, which subsequently improved the ability to automatically perform the stages of prosthetics. (Caspar system, Acrobot). Around the same time, the development of a robot for performing total knee arthroplasty began.

A distinctive feature of total knee arthroplasty (TKA) is the manufacturability of the stages and the high accuracy of surgical manipulations, which attracts the attention of many robotic surgical systems (RSS).

Traditional total knee arthroplasty (TKA) has now reached its maximum manufacturability and efficiency, but the accuracy of the performance depends on the skill and experience of the surgeon, as well as the accuracy of the cutting instrument (oscillator saw) when performing bone resection, the condition of the instrument and the density of the bone fabric, which is highly variable. The use of intramedullary guides during conventional surgery increases the risk of thromboembolic and cardiorespiratory complications. Computer navigation partially solves the problem of resection accuracy, infrared cameras read information from sensors and display a model with anatomical and kinematic features of the knee joint, which helps the surgeon to more accurately determine the level and direction of resection, but cannot ensure the accuracy of this manipulation and compliance with the preoperative plan.

Modern RSS used in orthopedics include a robotic arm, robotic cutting devices with a computer navigation system that operate in an active, semi-automatic, or passive control mode. The main advantage of robotic systems is accurate preoperative planning using 3D modeling, the possibility of individual selection of the implant and virtual positioning. Another advantage is the ability to accurately reproduce the preoperative plan during orthopedic surgery.

Today, active robotic surgical systems (ARSS) are used in clinical practice. ROBODOC / TSolution One. Robotic Surgical System (Curexo Technology, Fremont, Calif.), And Navio PFS (Blue Belt Technologies, Plymouth, Minnesota) Semi-Active Surgical Systems, OMNI Robotic System (OMNIlife Science, East Taunton, MA), RIO Robotic Arm Interactive Orthopedic System (Mako Surgical Corporation, Fort Lauderdale, Florida), ROSA Knee (Zimmer Zimmer Biomet, Montreal (Quebec), Canada).

The active robotic surgical system TSolution-One allows participants to level the error in the positioning of the implant. The accuracy of the filing is not affected by the manual skills of the surgeon, and does not depend on the density of bone tissue. Significant advantages of the system are: 1) precise preoperative breading; 2) rigid fixation of the limb, hip and tibia displacement sensors; 3) active autonomous milling without the participation of a surgeon; 4) accuracy of resection according to the preoperative plan; 5) rotation of the tibial component as in the preoperative plan; 6) no manual tools required; 7) postoperative control of the results of the operation. The active robotic surgical system (ARSS) allows participants to correctly install the implant, which affects its service life, reduces the risks of postoperative complications, the patient quickly returns to his usual way of life and forgets about those negative feelings and limitations that were before the operation.

The novelty of the proposed topic: For the first time in Russia, it is planned to introduce and study total knee arthroplasty using an active robotic system. Apply the use of a 3D patient model and the creation of an individual personalized preoperative plan using a robotic system for knee arthroplasty.
