The Modern Universal Total Knee Arthroplasty: Maximized Value, Streamlined Efficiency

Abstract

A universal total knee arthroplasty system able to accurately resurface either left or right knees of all shapes and sizes is compelling as there is an increased need for improved efficiency and value. With a modern universal total knee system, a single instrument tray can be utilized for more than 90% of cases and doesn’t require any specific customization or disposable instruments. This streamlined workflow is accomplished with unique instrumentation that features a symmetrical femoral and tibial implant for all patients. Symmetrical tibial implants have been shown to have equivalent outcomes and low complications compared to asymmetric tibial trays. The universal symmetrical femoral implant, with its deepened trochlear groove, allows for optimal patellar tracking and recent studies have demonstrated this symmetrical femoral implant to have comparable femoral rollback and axial rotation to native knees. This efficient instrumentation reduces overall inventory, decreases turnover times, and exposes fewer instruments that may otherwise be susceptible to contamination. All without detriment to the patient outcome or surgeon workflow. Studies have shown clinical scores of the modern universal total knee arthroplasty system are a great value not only to the surgeon but also to the healthcare system as a whole—a necessity in modern healthcare.
