  1. The study's title name Tibial Plateau Fractures, a narrower term within Tibial Fractures.
Confidence
High: the new condition is named in the study's own title. Of 46 hand-checked studies reclassified this way, 72% were exactly right and 89% in the right disease family; the registry's first term was right for 4% (measured 2026-10-21). How we classify →

Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

    Device: Norian Drillable Bone Void Filler

Interventions

  • DeviceNorian Drillable Bone Void Filler

    Norian Drillable Bone Void Filler is a moldable, biocompatible bone void filler with added reinforcing fibers. Norian Drillable is intended to be placed into bony voids either before or after final fixation. The material can be drilled and tapped, and screws can be placed through it at any time during the setting process. Norian Drillable is a composite, two-component, self-setting calcium phosphate bone void filler

    Also known as: Norian Drillable

SecondaryPain and Function Assessed With the Lysholm Knee Scale

The Lysholm Knee Score assessed pain and function of the knee (by evaluating whether support for weight bearing was needed, the patients ability to climb stairs and to squat, whether the patients knee was instable and the patient experienced pain and swelling) and was completed by the patient before surgery and at Week 6, Week 12, Week 26, Week 52, Week 78 and Week 104 (for Australian sites only). The score ranged from 0 to 100 points with higher values indicating a better healing status of the knee.

SecondaryRadiographic Parameters: Depression at Baseline

The anatomical grading parameter "depression" was assessed the following way: Anterior-Posterior (AP) and lateral radiographs were taken for the fractured and healthy tibia plateau at Baseline, right after surgery and all follow-up timepoint. Additional oblique radiographs at 45° or other fracture imaging was optional. All post-operative radiographs were compared against the healthy tibia films post-surgery and all follow-up radiographs were compared with the post-operative radiographs to evaluate the quality and changes in reduction at each timepoint. CT scans were only mandatory at Baseline.

Timeline

Tracking since Sep 25, 2026
Not marked actual or estimatedDates not marked actual or estimated

The record gives a start of Sep 2008, a primary completion of Sep 2013 and a completion of Sep 2013. It does not say whether these dates are actual or estimated.

Results were first posted in Jun 2015, 1 year 9 months after primary completion.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 11, 2015, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
