Robot assisted compared to conventional knee arthroplasty: metanalysis and systematic review

Area of Science:

• Orthopedic Surgery
• Robotics in Medicine
• Biomedical Engineering

Background:

• Robot-assisted surgery is a novel approach in total knee arthroplasty (TKA).
• It aims to enhance precision and accuracy compared to conventional manual techniques.
• Potential benefits for patient outcomes are being investigated.

Purpose of the Study:

• To systematically review and compare robot-assisted TKA with conventional TKA.
• To evaluate anatomical, mechanical, clinical, and functional outcomes.
• To assess complication rates and cost-effectiveness.

Main Methods:

• A systematic review following PRISMA 2020 guidelines.
• Searched multiple databases (PubMed/MEDLINE, Embase, Cochrane, Web of Science).
• Included comparative studies and controlled trials of robot-assisted vs. conventional TKA.

Main Results:

• Robot-assisted surgery demonstrated superior post-operative anatomical and mechanical restoration.
• Accuracy and alignment were significantly better with robotic assistance.
• Short-term patient outcomes favored robot-assisted procedures.
• Clinical results, functional outcomes, and complication rates were similar between groups.

Conclusions:

• Robot-assisted TKA provides enhanced precision in component positioning and alignment.
• Current evidence shows comparable patient outcomes and knee function in the short to medium term.
• Longer-term studies are needed to confirm superior clinical benefits.
• Cost-effectiveness is dependent on case volume and workflow optimization.
