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.

University Hospital, Strasbourg, France960 enrolled

Overview

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.

Outcomes

Primary Outcomes

IKS / KSS (Knee Society Score)

The classic IKS (often called KSS) has 2 separate scores, each out of 100 points: 1. Knee Score (Objective / Clinical) - 0 to 100 Assesses the knee itself: * Pain (0-50) * Range of motion (0-25) * Stability (0-25) 2. Function Score - 0 to 100 * Assesses patient function: * Walking distance (0-50) * Stair climbing (0-50) Interpretation (commonly used): * 80-100: Excellent * 70-79: Good * 60-69: Fair * \< 60: Poor

Time frame: Up to 12 months
