[Radiological examination of knee prostheses]

Area of Science:

• Orthopedic surgery
• Medical imaging
• Biomedical engineering

Background:

• Knee replacement surgery involves selecting appropriate prostheses (single-compartment, three-compartment, hinge) based on patient anatomy.
• Preoperative radiological assessment is fundamental for guiding surgical decisions and planning.
• Accurate prosthesis placement is vital for long-term joint function and patient satisfaction.

Purpose of the Study:

• To define indications for different knee prostheses based on radiological findings.
• To outline radiological criteria for successful implantation of various knee prostheses.
• To highlight the importance of regular radiological follow-up for detecting complications after knee arthroplasty.

Main Methods:

• Review of preoperative radiological assessments to determine prosthesis type.
• Description of radiological signs indicative of correct implantation for single-compartment, three-compartment sliding, and hinge prostheses.
• Emphasis on serial radiological monitoring post-surgery.

Main Results:

• Preoperative imaging effectively guides the selection of appropriate knee prostheses.
• Specific radiological markers confirm accurate placement of different prosthesis types.
• Radiological follow-up identifies potential complications such as instability, loosening, wear, and infection.

Conclusions:

• Radiological assessment is indispensable for both operative planning and confirming correct knee prosthesis implantation.
• Regular radiological surveillance is essential for early detection and management of complications, preserving the patient's osteoligamentous integrity and functional prognosis.
