[Application of remote sensing navigation system in total knee arthroplasty]

Area of Science:

• Orthopedic Surgery
• Medical Technology
• Biomedical Engineering

Context:

• Total knee arthroplasty (TKA) is a common procedure for end-stage knee osteoarthritis.
• Accurate alignment of prostheses is crucial for optimal TKA outcomes.
• Traditional surgical navigation methods have limitations in precision and ease of use.

Purpose:

• To evaluate the clinical accuracy of the remote sensing navigation alignment (RSNA) system in TKA.
• To assess the influence of the RSNA system on postoperative clinical efficacy compared to traditional methods.

Summary:

• A study compared the RSNA system with traditional methods in 60 TKA patients.
• RSNA demonstrated a significantly lower rate of lower limb force line defects and improved prosthesis alignment (FPVA, FPFA).
• Postoperative functional recovery (WOMAC, KSS) was similar between groups at 6 months.

Impact:

• The RSNA system offers enhanced accuracy and ease of operation for TKA.
• It reduces critical alignment errors, potentially leading to better long-term implant survival.
• RSNA represents a valuable advancement in navigation technology for knee replacement surgery.
