Behandling
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

Pain and Function Assessed With the Lysholm Knee Scale
Tidsramme: 6 weeks, 12 weeks, 26 weeks, 52 weeks, 78 weeks and 104 weeks (for Australian sites only)
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.

Radiographic Parameters: Depression at Baseline
Tidsramme: 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.
