Posterior instability after mobile bearing total knee replacement may be caused by gap imbalance, component malpo- sition, and delayed rupture of posterior cruciate ligament, but could not be easily considered other cause except component breakage in fixed bearing posterior cruciate substituted total knee replacement.

We report a case of dislocation of tibial polyethylene insert that have been found at a patient who had continuing posterior instability after fixed bearing posterior cruciate ligament substituted total knee replacement with a review of article.
