Patient Specific Instruments and Patient Individual Implants-A Narrative Review

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Medical Innovation

Background:

• Joint arthroplasty is a common surgical procedure globally.
• Patient-specific implants and instruments are emerging innovations in joint replacement.
• Current data suggests potential benefits, especially in revision arthroplasty.

Purpose of the Study:

• To review current data on patient-specific implants and instruments in joint arthroplasty.
• To evaluate the emerging role and effectiveness of personalized surgical tools.
• To highlight applications in knee, hip, shoulder, and ankle surgeries.

Main Methods:

• Systematic literature review of studies on patient-specific implants and instruments.
• Analysis of data concerning surgical outcomes, particularly in revision scenarios.
• Comparison of patient-specific implants versus patient-specific instruments.

Main Results:

• Promising outcomes reported for patient-specific implants and instruments, especially in revision arthroplasty.
• Knee and hip arthroplasty show the most extensive experience with these personalized approaches.
• Patient-specific instruments are less common for shoulder and ankle procedures.

Conclusions:

• Patient-specific implants and instruments demonstrate potential benefits in joint arthroplasty.
• Further studies are required to fully establish the long-term utility and efficacy.
• Personalized surgical solutions show particular promise for complex revision joint surgeries.
