Abstract

The purpose of this study is to report the incidence, management, and outcomes of periprosthetic fractures associated with the insertion of press-fit stems during revision total knee arthroplasty (TKA). Immediate and six week post-operative radiographs from 634 stemmed implants (307 femoral, 327 tibial) from 420 consecutive revision TKAs were reviewed. Sixteen tibial (4.9%) and 3 femoral (1%) fractures (combined incidence 3.0%) were identified. All healed uneventfully without operative intervention, with no evidence of implant loosening at a mean of 23. months (range 12 to 47. months). The technique of tightly press fitting stems into the diaphysis is associated with a small rate (3%) of periprosthetic fractures; most were non or minimally displaced, all healed uneventfully with non-operative management and were not associated with implant loosening.
