Howmed: Howmedica recalls knee prostheses with Lot CTD44301 due to oversized baseplate that may prevent insert from locking. Affected units have specific model and lot number.
Stryker has discovered that the internal profile of the Triathlon Tritanium Tibial Component (Baseplate), size 4, is potentially oversized. Due to a manufacturing issue in Lot Number CTD44301, there may be a witness mark (taper) at the bottom of the internal profile of the baseplate. The taper prevents the insert from locking on the baseplate.
