“…The knee hyperextension position must be avoided after PS-TKA. Watanabe et al [7] reported on the kinematic analysis of 40 well-functioning total knee arthroplasties (Actiyas®) and concluded that one-third of the knees with high-flexion PS-TKA had anterior impingement at the final of the gait stance phase and at the initial swing phase. To avoid anterior post impingement, they advised the posterior tibial slope must be cut with at 5˚ or less of posterior inclination.…”

Background: Tibial polyethylene wear is related late failure in total knee arthroplasty. The cruciate substitute design depending on the cam-post 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.
