Arthroplasty Implants Designed by Surgeons

The Symmetric Knee Systems utilize a single-radius femoral component, optimized polyethylene surface contact for stress distribution, and a Micro Seal® locking mechanism for secure component integration. Additionally, they feature an arc-deposited titanium coating to support implant stability and longevity

These knee arthroplasty solutions, designed by Dr. Leo Whiteside and previously manufactured by Signal Medical, are now exclusively manufactured by Medisurge and distributed by Alliant Biotech.
