Yep, the “Stryker Triathlon® Knee System” is a great series of replacements. My buddy got one a decade ago, then this year he got a newer model for the other knee. 6 weeks after the replacement surgery, he was refereeing an ice speedskating meet.
I got a Global Medacta Total Knee replacement. Two and a half weeks after surgery, I was walking a 2¼ mile loop.
