Those of us that remember the centerpulse acquisition in 03 or Abbott spine will know that Zimmer favors their own designs to others. Biomet's portfolio won't get the same focus going forward. How does the same company tout two different brands of vit E poly? Ans: one gets ignored. The ZUK and the oxford might do okay because they're different enough from each other to both have value to different surgeons, but the Oxford won't get the singular focus it has enjoyed and won't be used as a door opener to the degree that it has in the past.
The total knee systems have a lot of overlap. They'll want to keep both sales forces around to service the same volume they always have. The warehouses will be combined and some distributors will lose out, but the average rep may do fine for several years. The real "savings" will come from 2 legal departments, purchasing, manufacturing, contracts, management from the director up, quality, sterilization, lab work etc.
Anything in the pipeline that is redundant will be re-evaluated with a new eye. Do I need a new baseplate for the vanguard or can I make a crossover poly to allow the use of persona femurs with vanguard baseplates. Hmmm this is fun. I probably don't need the new instrument set for the vanguard femurs that was being developed in response to the persona instruments so with these crossover polys. I could eliminate a few engineers with that change. And so on...
