BKS TriMax®

Evolution of stability and balance.

Building on the 20-year clinical heritage of the BKS® Knee System, BKS TriMax represents the next step in the evolution of total knee arthroplasty. Key design refinements in the BKS TriMax enable surgeons to improve achievement of alignment and stability while promoting bone conservation and operative efficiency.
