摘　　要：Background: Tibial polyethylene wear is related late failure in total knee arthroplasty. The cruciate substitute design depending on the campost mechanism to secure the knee cinematics after a posterior stabilized total knee arthroplasty (PS-TKA). A post fracture can occur after damage failure of the post. Aim: Report a case of post refracture after a PS-TKA and review the lecture about post wear in PS-TKA. Case presentation: A 63 woman with a primary TKA had a diagnosis of polyethylene post fracture. The polyethylene exchange wasn’t enough and revisions of all components were necessary. Conclusion: In patient with previous well function, subtle swelling and giving away sings after PS-TKA, a post fracture must be excluded.Background: Tibial polyethylene wear is related late failure in total knee arthroplasty.
