Study of the Clinical and Radiographic Results of a Fixed Polyethylene Posteriorly Stabilized Cemented Total Knee Prosthesis With a Minimum Follow-up of 1 Year.

Study of the Clinical and Radiographic Results of a Fixed Polyethylene Posteriorly Stabilized Cemented Total Knee Prosthesis With a Minimum Follow-up of 1 Year.

The knee replacement market is experiencing constant growth. Alongside this growth, there is also an increasing interest in customizing implantation based on specific phenotypes to restore the morphology of the native knee. For example, in the last five years, 2019 publications on knee prosthesis alignment have been identified on PubMed.

It seems worthwhile to study and analyze the performance of the prosthesis used in the Orthopedic Surgery Department of the Strasbourg University Hospitals (HUS) and to compare it with results from the literature.
