“…Previous retrieval studies of the tibial post in PS TKAs focused on gross fracture of the post and the wear damage mechanisms experienced by the post because it acts as a constraint to tibiofemoral translation and rotation [1,4,5,9,13]. Few studies included design as a factor influencing post wear damage.…”

“…The tibial polyethylene post in posterior-stabilized (PS) TKA designs is a source of substantial wear debris, and retrieval analyses demonstrated evidence of post wear on 100% of the implants examined [5,13,22]. In severe cases, this wear can lead to fracture of the tibial post, resulting in instability and revision knee arthroplasty.…”

“…In addition to this large report of 70 tibial post fractures, and an earlier report of five fractures with the same prosthesis [27], there are only 27 total reported cases of tibial post fractures in 18 published articles (Table 1) in the English language during the past 10 years [3, 5, 8, 9, 11, 14, 15, 17-20, 23, 25, 26, 28-30, 32]. In these case series, the highest incidence was 1.2% [15], with most reporting less than 1%. As the prosthesis with a central hole in the post had an obvious design flaw, cases using it will be analyzed separately from the other 27 reported cases.…”

“…Hendel et al reported an incidence of 1.2% (five of 332) with the Insall-Burstein II prosthesis (Zimmer) implanted during a 5-year period at one center [15]. In another study of this prosthesis, the incidence of tibial post fracture was 0.51% (one of 193 knees) with 5 to 14 years followup [20].…”
