Polyethylene Tibial Post Fracture in a Posterior Stabilized (Genesis II) Total Knee Arthroplasty

This study reports the case of a fractured polyethylene tibial post in a 49-year-old white male patient at 4 years status post a left posterior stabilized total knee arthroplasty. The patient was doing extremely well postoperatively until he felt pain in the left knee while completing personal resistance squats. He was found to have anterior/posterior instability in flexion as well as midflexion instability. The patient underwent removal of the fractured polyethylene insert and replacement with a thicker insert. The patient had immediate resolution of his preoperative pain and instability. To our knowledge, this is the first reported case of a polyethylene tibial post fracture in a Genesis II total knee system (Smith and Nephew; Memphis, TN).[...]Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.Article in Thieme eJournals:Table of contents  |  Abstract  |  open access Full text
