About this study
Official title: Randomized Control Trial Comparing Zimmer Biomet Persona Medial Congruent Versus Posterior Stabilized Total Knee Arthroplasty for Treatment of Knee Arthritis Using the ROSA Knee System
A randomized, controlled study comparing two total knee implant devices, Persona medial congruent (MC) vs posterior stabilized (PS). These surgeries will be performed using the ROSA robotic system. Patients will be followed up to 5 years.
- Conditions
- Total Knee Arthroplasty
- Being tested
- Zimmer-Biomet Persona Medial Congruent (MC) Bearing Design, Zimmer-Biomet Persona Posterior-Stabilized (PS) Bearing Design
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Zimmer-Biomet Persona Medial Congruent (MC) Bearing DesignDevice
TKA will be performed using the MC Bearing Design. The MC bearing provides medial stability and lateral mobility to facilitate more natural motion.
Zimmer-Biomet Persona Posterior-Stabilized (PS) Bearing DesignDevice
TKA will be performed using the PS Bearing Design. The PS bearings are designed to provide ±1.5 degrees varus/valgus constraint and ± 5.5 degrees internal/external rotation constraint.

What is being measured
The primary outcome is the main question the study is designed to answer.
Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS, JR)
KOOS, JR contains 7 items from the original KOOS survey. Items are coded from 0 to 4, none to extreme respectively. KOOS, JR is scored by summing the raw response (range 0-28) and then converting it to an interval score. The interval score ranges from 0 to 100 where 0 represents total knee disability and 100 represents perfect knee health.

European Quality of Life Five Dimension (EQ-5D) Score
The EQ-5D comprises five questions on mobility, self care, pain, usual activities, and psychological status with three possible answers for each item (1=no problem, 2=moderate problem, 3=severe problem. A summary index with a maximum score of 1 can be derived from these five dimensions by conversion with a table of scores. The maximum score of 1 indicates the best health state, by contrast with the scores of individual questions, where higher scores indicate more severe or frequent problems. In addition, there is a visual analogue scale (VAS) to indicate the general health status (0-100) with 100 indicating the best health status.

The EQ-5D comprises five questions on mobility, self care, pain, usual activities, and psychological status with three possible answers for each item (1=no problem, 2=moderate problem, 3=severe problem. A summary index with a maximum score of 1 can be derived from these five dimensions by conversion with a table of scores. The maximum score of 1 indicates the best health state, by contrast with the scores of individual questions, where higher scores indicate more severe or frequent problems. In addition, there is a visual analogue scale (VAS) to indicate the general health status (0-100) with 100 indicating the best health status.

European Quality of Life Five Dimension (EQ-5D) Score
Time frame: Year 5
The EQ-5D comprises five questions on mobility, self care, pain, usual activities, and psychological status with three possible answers for each item (1=no problem, 2=moderate problem, 3=severe problem. A summary index with a maximum score of 1 can be derived from these five dimensions by conversion with a table of scores. The maximum score of 1 indicates the best health state, by contrast with the scores of individual questions, where higher scores indicate more severe or frequent problems. In addition, there is a visual analogue scale (VAS) to indicate the general health status (0-100) with 100 indicating the best health status.
