About this study
Official title: Persona® TM Tibia Clinical Outcomes Study: Prospective Multicenter Study of the Persona® Trabecular Metal Tibia
The primary objective of this study is to evaluate clinical performance for the commercially available Persona TM Tibia used in primary cementless tibia total knee arthroplasty.
Read the detailed description
This is a prospective, multicenter, non-randomized clinical study designed to facilitate the collection and evaluation of radiographic parameters, pain and function, survival of the device,and adverse event data.
The study will require each site to obtain IRB approval prior to study enrollment. All potential study subjects will be required to participate in the Informed Consent Process.
All study subjects will undergo preoperative clinical evaluations prior to their cementless tibia total knee arthroplasty. An immediate postoperative radiograph will be required. Postoperative clinical follow-up and radiographic evaluations will be conducted at 6 weeks, 6 months, 1 year, and 2 years.
The primary endpoint of this study is to evaluate the clinical performance of the implant at 2 years postoperatively using radiographic parameters. Radiographs will be assessed for the absence of progressive tibial radiolucencies, as defined in the radiographic protocol.
The secondary endpoints of this study will evaluate the clinical performance of the implant at 2 years postoperatively, based upon:
- No revisions for any reason
- Oxford Knee Score >38
- Conditions
- Osteoarthritis, Rheumatoid Arthritis, Traumatic Arthritis, Polyarthritis, Collagen Disorders and/or Avascular Necrosis of the Femoral Condyle, Post-traumatic Loss of Joint Configuration
- Being tested
- Persona TM Tibia
- Medical subject headings
- Osteoarthritis, Arthritis, Rheumatoid, Arthritis
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Persona TM TibiaDevice
Trabecular Metal tibia used in primary cementless total knee arthroplasty
| Study group | Role | What they receive |
|---|---|---|
| Persona TM Tibia subjects | Other | Subjects that receive the Persona TM Tibia implant Receives: Device: Persona TM Tibia |
What is being measured
The primary outcome is the main question the study is designed to answer.
Radiograph Assessment of Progressive Tibial Radiolucencies
Progressive tibial radiolucency will be derived in accordance with the following definitions:
Absent: No evidence of an increase in either radiolucency extent (number of zones involved) or measured width within a zone.
Present: Presence of either: An increase in the number of zones with a measured tibial radiolucency, OR an increase in the measured tibial radiolucency width within a zone of >0.5 mm.
Unable to assess: One or more of the component factors necessary to derive progressive tibial radiolucency is unavailable.
Measured: 2 years
Secondary outcomes (2)
Oxford Knee Score
The Oxford Knee Score is a patient completed 12 question metric to rate a patient's knee pain and function using an ordinal 0 - 4 point scale. The total score is obtained by calculating the sum of the 12 items. The maximum score is 48 points (best) and the minimum score is 0 points (worst).
Measured: 2 years
Revision Rate
Rate of the number of revisions for any reason
Measured: 2 years

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 11 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 23 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 23 Jul 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Radiograph Assessment of Progressive Tibial Radiolucencies (time frame: 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jul 2024.
