Tibial post fracture after posterior stabilized total knee replacement (TKR) is a uncommon and disabling complication. We report two cases of non-traumatic tibial post fracture, which presented with sudden pain and recurvatum instability in joint replacements with good previous function. For the first case, the presentation time was 12 years from the primary TKR, and for the second it was 14 months. Both presented the same model of a posterior stabilized prosthesis. In both cases, a revision TKR was performed with a rotating hinge prosthesis (Endo-Model NR®, Waldemar Link), without recurrence of the deformity.
