20. An implant system, comprising:
-
a single threaded post comprising a first tapered portion and a coupler configured to engage with a driver such that rotation of said driver causes said post to threadably engage bone beneath a patient'"'"'s articular surface; and an implant comprising a load bearing surface, a second tapered portion, and a non-planar bone facing surface having a contour that is symmetrical around said second tapered portion; wherein said first and said second tapered portions are configured to engage each other in a frictional interference fit and couple said post to said implant, wherein said first and said second tapered portions are further configured to allow said implant to be aligned into a final alignment with respect to said articular surface and said post before said implant is secured to said post. - View Dependent Claims (21, 22)
