Primary knee

The Sartori knee prosthesis has an anatomical design and an articular region with dimensional congruence for stability in the condyles in extension and even high flexion.
It also has a surface with high precision machining on the articular profile and automated finishing, promoting a highly polished surface and minimizing tribological wear with polyethylene.
The components that make up the Knee Arthroplasty System are classified as a surgically invasive implantable medical product for permanent use.
The system was developed to withstand compression, shear and torsional loads. In this way, it assists in stabilization, and in the transmission or relief of mechanical loads on the injured segment.
The components of the system connect to each other so that the intended performance exerts its functionality, that is, they replace the joint in a procedure (primary or revision), in skeletally mature patients, who have good bone stock and whose ligaments have been
provide adequate medio-lateral, anteroposterior and varus/valgus stability.

The Restricted Knee Arthroplasty System is indicated for:

- Osteoarthritis;
- Severe inflammatory degenerative diseases;
- Intra-articular osteoporotic fractures of the femoral shaft and proximal tibia;
- Neoplastic conditions around the knee unsuitable for other types of implants;
- Degenerative, rheumatoid or post-traumatic arthritis;
- Post-traumatic loss of the configuration and function of the knee joint;
- Failure of the first implant prosthesis (for example: infection, instability, lack of fixation in the case of a non-cemented prosthesis, wear of components, mobilization, etc.);
- Correction of malposition in varus, valgus or flexion;

The function of the Restricted Knee Arthroplasty System is to replace the tibial and femoral surface, the objective of which is to reconstruct the damaged parts of this region, with the aim of reducing pain, correcting deformities and/or instabilities, improving function in degenerative knee diseases, and restoring patients' quality of life.
The selection criteria for the size of the implant to be used will depend on the condition of the bone and the technique to be adopted to carry out the procedure. These conditions are the responsibility of the doctor who evaluates the patient and decides which implant should be used.
The system is indicated for patients who have good bone stock and whose ligaments are
They have adequate mediolateral, anteroposterior and varus/valgus stability.
