Knee
Total knee replacement with Rosa robot
treatment
The use of the ROSA Robot during PTG ( total knee prosthesis)placements.
Provides feedback for ligament and soft tissue tension adjustment. Bone resections are very precise, aiming to restore the patient's natural knee.
ROSA Knee collects intra-operative data to improve decision-making and provides data-driven information to achieve an optimal result for each patient.
Bone cuts are made with greater precision, maintaining ligament tension close to that of the native knee, with physiological correction of the limb axis. A 2020 study by Seidenstein et al. concludes that the angle error is around 3° in conventional surgery without a robot.
As the prosthetic knee with ROSA more closely resembles the native knee, recovery is faster.
diagnosis
Confirmation of the diagnosis can be straightforward, sometimes requiring a simple X-ray.
symptoms
- Intense knee pain limiting daily activities (walking, climbing stairs, standing)
- Pain at rest, even at night
- Joint stiffness reducing range of motion
- Chronic swelling or persistent inflammation despite rest or treatment
- Knee deformity (bowed legs or X-shaped knees)
- Failure of conservative treatments such as physiotherapy, infiltrations or medication
- Advanced osteoarthritis, rheumatoid arthritis or post-traumatic osteoarthritis visible on imaging
- Poor quality of life due to persistent joint problems
Definition
ROSA (Robotic Surgical Assistant) is a surgical robot used to assist surgeons during total knee replacement surgery. Thanks to cutting-edge technology combining medical imaging, sensors and a robotic arm, ROSA enables personalized planning of the operation and greater precision during implant placement. It helps optimize prosthesis alignment and balance, which can improve functional results and reduce patient recovery time.
