Persona MC vs PS Total Knee Arthroplasty Study
This study is comparing two different knee implant designs, the Zimmer-Biomet Persona Medial Congruent (MC) and the Zimmer-Biomet Persona Posterior-Stabilized (PS), used during total knee replacement surgery (Total Knee Arthroplasty or TKA). Both surgeries will be performed using the ROSA robotic system. We are looking for 200 adults, aged 18 and older, who are scheduled for a primary TKA due to osteoarthritis or inflammatory arthritis. The main goal is to see how well your knee functions and how much pain you have, using a score called KOOS, JR, at 6 weeks and 3 months after surgery. The current recruitment status is unclear.
- Study design
- This is a randomized, controlled study comparing two knee implant devices. It plans to enroll 200 participants.
- What's involved
- You would undergo total knee replacement surgery and follow a study protocol and visit schedule. You also need a device that can pair with an Apple Watch.
- Compensation
- Not stated in the trial record.
- Follow-up
- Participants will be followed for up to 5 years after their surgery.

What this trial measures
- Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS, JR)Baseline
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.

- Forgotten Joint Score (FJS)Baseline
FJS is a patient-reported outcome measure intended to determine a patient's ability to "forget" about their affected joint after surgery or treatment. FJS consists of 12 questions - the total score range is 0-100. The higher the score, the less the patient is aware of their affected joint when performing daily activities.

- European Quality of Life Five Dimension (EQ-5D) ScoreBaseline
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.
