SOLUTIONS GRADED A+
● -3mm for sizes 1-7 (53mm for size 1 to 71mm at size 7)
-4mm for sizes 7 to 8 (75mm at size 8). Answer: ● In millimeters, how
much do the femoral sizes grow anterior to posterior?
● 3mm for sizes 1-7 and 4 for size 7-8; no growth occurs posterior to the
lugs. Answer: ● In millimeters, how much do the femoral sizes grow
posterior to anterior - from the pegs?
● 3mm per size (59mm M/L width for size 1 to 80mm M/L width for
size 8). Answer: ● In millimeters, how much do the femoral sizes grow
medial to lateral?
● 8mm. Answer: ● In millimeters, how thick are the distal condyles on
the femoral components?
● 8 mm. Answer: In millimeters, how thick are the posterior condyles on
the femoral components?
● +/- 1 size. Answer: ● What is the "up/down" interchangeability
between the femoral and tibial implants?
, ● Pegs are not optional, fixed to femoral implant. Answer: ● Are there
optional pegs on a Triathlon CR femoral component?
● Yes, pegs are modular, not required. Answer: ● Are there optional pegs
on a Triathlon PS femoral component?
● 150°. Answer: ● The Triathlon Primary CR/PS (TS insert not applied
here!) femoral/tibial construct has no bio-mechanical constraint up to
how many degrees of flexion?
● Designed to provide the flexibility to downsize the femoral component
while avoiding the incidence of notching. Answer: ● What is the benefit
of the 7-degree anterior flange on the Triathlon femoral component?
● +/- 20°. Answer: ● How much internal/external rotation can the
Triathlon CR/PS femoral component achieve (TS insert not applied
here!)?
● Cobalt Chrome. Answer: ● The cemented Triathlon CR/PS femoral
components are made from what alloy?
● No, they are coated with cobalt chrome beads and are available with
or without Peri-apatite (PA) technology which is Stryker's technology
for application of HA to three dimensional beaded constructs. Answer: ●
Do the cementless Triathlon CR/PS femoral components have Tritanium
undersurfaces?
