Abstract:
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. The dislocation of tibial polyethylene insert was reported after mobile bearing total knee replacement but rare after fixed bearing 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.
