Multi-center, Non-comparative Study of Primary Total Knee Arthroplasty (TKA) Functional Performance
This post-marketing investigation will evaluate the functional knee performance of Subjects who have undergone primary total knee arthroplasty (TKA). Data from Subjects who receive one of four contemporary knee configurations from different manufacturers will be pooled to establish a contemporary dataset.
The primary objective of this study is to evaluate the functional performance as measured by the activities of daily living (ADL) sub-score of the Knee Osteoarthritis Outcomes Score (KOOS) patient-reported outcome (PRO) questionnaire of primary TKA at minimum one year post-operation. This will be carried out for all four implant configurations. The final endpoint is a 2-year evaluation.
Tutkimuksen yleiskatsaus
Yksityiskohtainen kuvaus
The study is designed as a prospective, single arm stratified, multi-center investigation.
Approximately 20 study sites, worldwide, will enroll 840 patients (840 knees). Each study site is expected to enroll approximately 42 patients (42 knees). Cohort reallocation is permitted. There will be no control group. Eight hundred forty (840) Subjects will be stratified into 4 subgroups of 210: fixed bearing cruciate retaining (FB CR), fixed bearing posterior stabilized (FB PS), rotating platform cruciate retaining (RP CR), and rotating platform posterior stabilized (RP PS).
Treatment assignment in this study is not randomized. Each site will only enroll patients in one of the four knee configuration sub-groups most commonly used as their standard of care.

The primary endpoint will be measuerd before surgery and out to a minimum of 1 year after surgery.
The KOOS is a patient self-administered questionnaire that consists of 42 questions.
The KOOS consists of 5 subscales; pain, other symptoms, activities of daily living (ADL), sport and recreational function and knee-related quality of life.
Each question has 5 Likert-like response options.
A normalized score (100 indicating no symptoms and 0 indicating extreme symptoms) is calculated for each subscale.
