Smith+Nephew’s VISIONAIRE Patient-Specific Instrumentation Improves TKA Outcomes

Smith+Nephew released a systemic literature review and meta-analysis of its VISIONAIRE patient-specific instrumentation (PSI) showing its use leads to improvements in alignment accuracy, procedural efficiency, and reduction in length of hospital stay compared to conventional instrumentation.
 
25 relevant studies published by the Archives of Orthopaedic and Trauma Surgery were included in the meta-analysis comparing VISIONAIR PSI-enabled total knee arthroplasty (TKA) with conventional instrumentation-enabled TKA. Patients who received VISIONAIRE PSI- enabled TKA  showed the following results:

• 40% reduction in odds of an outlier in the mechanical axis
• More efficient operations with reductions in operating room time, turnover time, and tourniquet time
• 53% reduction in odds of needing a blood transfusion
• 11.1% reduction in mean length of hospital stay

 
This meta-analysis poffers evidence of reduced odds of mechanical axis outliers versus conventional instrumentation.
 
“Utilizing Smith+Nephew’s VISIONAIRE preoperative planning and intraoperative cutting guides has allowed me to be more accurate, less invasive, and more efficient with both inpatient and outpatient total knee replacements,” Dr. Ravi Bashyal, Orthopedic Surgeon and Director of Outpatient Hip and Knee Replacement Surgery at NorthShore University Health System, told the press. “This has resulted in improved outcomes, streamlined tray utilization, and ultimately a happier, more satisfied surgeon and patients. It’s even been shown in a retrospective study that total hospital costs were statistically significantly lower for TKA with VISIONAIRE than TKA without PSI.”
 
The patient-specific instrumentation includes customized cutting guides to reduce the number of steps and surgical instruments needed for surgery compared to conventional TKA. The guides are designed from surgeon-specific preferences, then developed by a dedicated engineer, allowing for personalized performance.
