Arthroplasty Complications Infection Knee Disease Knee Osteoarthritis | Device: Persona Revision Knee System |
Under study are the Persona® Revision Knee System (K181947 and K191625) implants and instrumentation, and any compatible devices being used in conjunction according to the Instructions for Use. This will be accomplished by retrospectively identifying patients who underwent primary or revision TKA with this system and inviting them to participate in prospective data collection at 1 and 2-years postoperative follow-up. As the device was not available for commercial use until late 2019, the retrospective portion will involve those activities that occurred per standard of care for participants.
The primary endpoint for this study will be performance assessed by improvement in the 1989 Knee Society Clinical Rating System (KS) objective knee score (KS-KS) from baseline to 2 years (as evaluated using the overall group mean showing at least the Minimal Clinically Important Difference (MCID) of 5.4 points).
A maximum of 20 sites will contribute to this study. There will be a maximum of 380 patients enrolled in the study.

- Knee Society Clinical Rating System objective knee score (KS-KS) [ Time Frame: 2 years ]
The primary endpoint for this study will be performance assessed by improvement in the 1989 Knee Society Clinical Rating System (KS) objective knee score (KS-KS) from baseline to 2 years (as evaluated using the overall group mean showing at least the minimal clinically important difference [MCID] of 5.4 points)
The Knee Society objective knee score (KS-KS) assesses the knee joint by awarding points for pain, stability, and range of motion, with a minimum possible score of 0 and maximum possible score of 100. As described in Insall et al. (1989), "100 points will be obtained by a well-aligned knee prosthesis with no pain, [at least 121] degrees of motion, and negligible anteroposterior and mediolateral instability."
- Incidence and frequency of adverse events. [ Time Frame: 2 years ]Safety of the device will be assessed by evaluating the incidence and frequency of adverse events including (re-)revision of any component during the study in accordance with Regulation (EU) 2017/745 - Medical Device Regulation (MDR) Article 80(2) as well as Medical Devices Coordination Group (MDCG) 2020-10/1.
- Numeric Rating Scale (NRS) Pain Score [ Time Frame: 2 years ]
Performance and clinical benefits will be assessed by evaluating improvements in patient reported outcome measures (PROMs) of the Numeric Rating Scale (NRS) pain scores from baseline to 2 years.
The Numeric Rating Scale (NRS) pain is scored on a scale of 0 to 10. A score of 0 indicates that the patient is experiencing no pain in their knee joint while a score of 10 indicates that the patient is experiencing the worst possible pain in their knee joint.
- Knee Injury and Osteoarthritis Outcome Score Junior (KOOS-Jr) [ Time Frame: 2 years ]
Performance and clinical benefits will be assessed by evaluating improvements in patient reported outcome measures (PROMs) for the Knee Injury and Osteoarthritis Outcome Score Junior (KOOS-Jr) subscale scores from baseline to 2 years.
The Knee Injury and Osteoarthritis Outcome Score Junior (KOOS-Jr) is scored on a scale of 0 to 100. A score of 100 indicates that a patient is experiencing perfect knee health while a score of 0 indicates that a patient is experiencing total knee disability.
- Radiographic Imaging [ Time Frame: 2 years ]Exploratory outcomes will include the evaluation of radiographic imaging as required for adverse event/complication reporting purposes with focus on the following parameters: radiolucency lines, component migration/subsidence, osteolysis, and localized osteopenia.
