Robotic joint replacements have revolutionized the field of orthopaedic surgery, providing advanced technology for enhanced precision and patient outcomes. Robotic surgery allows for a Kinematic Alignment (KA) approach to total knee joint replacements.
These procedures involve the use of robotic systems to assist surgeons in performing joint replacements, such as hip or knee replacements. Using sophisticated imaging techniques, the robot produces a 3D virtual model of the joint. This model provides the surgeon with a highly accurate representation of the patient’s anatomy, including bone structure, joint alignment and soft tissue characteristics. This information is used by the surgeon to determine the optimal implant size, placement and alignment for the specific patient.
During actual surgery, the robotic system uses real-time tracking technology to precisely position and align the instruments and implants according to the preoperative plan.
The main advantage of robotic joint replacements is the improved accuracy and customization they offer. Robotic systems can create a detailed virtual model of the patients joint, allowing for precise preoperative planning and intraoperative guidance. This can result in better alignment, reduced complications, and improved long-term functionality for patients.
Robotic joint replacements minimize soft tissue damage (soft tissue sparing) and reduce postoperative pain. In addition, the robot is used for a Kinematic alignment approach to Total knee replacement surgery.
The cost of robotic systems can be high, which may limit accessibility for some patients. Additionally, the learning curve for surgeons to adopt and become proficient in using robotic technology can be steep. Finally, there is still a need for long-term studies to fully access the durability and lifespan of robotic joint replacements.
Kinematic Alignment in total knee replacements have increased in popularity. This approach aims to restore 3 aspects of the patients own knee anatomy: bone morphology, soft tissue balance and hip-knee-ankle alignment (i.e. to restore the patient’s pre-arthritic knee anatomy and function).
The ‘one-size-fits-all’ concept of traditional knee replacements have led to a significantly high dissatisfaction rate (20%) amongst patients. The Robotic Kinematic Alignment approach to total knee replacements is different between patients and is a personalised, patient-specific approach. This approach has resulted in good short-term and medium-term clinical results.
While robotic joint replacements have clear advantages in terms of precision and customization a careful consideration should be given to individual patient needs and resources.
