Inclusion criteria
Inclusion criteria: Patients: -Tibial plateau fracture (AO classification B3 or C) sustained within 12 months of the study start and surgically treated at the BG Injury Clinic Frankfurt am Main. -Legal age of majority (minimum age 18 years) at the time of fracture treatment. -Body Mass Index (BMI) < 35 (required for the technical execution of the gait analysis). -Availability of pre- and postoperative cross-sectional imaging (CT/MRI) of the affected knee. -Written informed consent for study participation and data processing. Orthopedically healthy subjects (Control group): -Age between 18 and 80 years. -Body Mass Index (BMI) < 35. -Ability to stand and walk independently without assistive devices. -Written informed consent for study participation.
Exclusion criteria
Exclusion criteria: Patients: -Missing pre- or postoperative cross-sectional imaging. -Severe internal or cardiovascular comorbidities making study participation unreasonable. -Pre-existing manifest osteoarthritis of the hip, knee, or ankle joint (Kellgren-Lawrence score > 2) or presence of joint arthroplasty in these joints. -Surgical interventions on the musculoskeletal system within the last 6 months prior to the tibial plateau fracture, or history of spinal surgery. -Previous joint infections or destructive rheumatoid arthritis. -Neurological disorders of any form (e.g., Parkinson's disease, stroke with residual paralysis, multiple sclerosis, epilepsy, muscular dystrophy, cerebral palsy). -Intake of medications that impair gait patterns or alertness. -Refusal or withdrawal of informed consent. Additionally for orthopedically healthy subjects: -Current symptoms or previous injuries of the upper or lower extremities. -Axis deformities > 10 cm regarding the epicondylar or malleolar distance. -Flexion contractures of the knee joint > 15°.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Peak dynamic knee joint loading, measured via knee joint moments in the frontal plane during gait (Nm/kg) using marker-based 3D gait analysis and force plates at 6 and 12 months postoperatively. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Kinematic parameters (range of motion/ROM, static/dynamic mechanical leg axis, knee stability) at 6 and 12 months. 2. Spatiotemporal gait parameters, balance capacity (60s standing test), and weight distribution during standing at 6 and 12 months. 3. Clinical parameters (ROM via neutral-zero-method, postoperative complications/revisions) at 8 weeks, 6, and 12 months. 4. Patient-reported outcomes (Tegner Activity Score, Lysholm Score, KOOS, SF-12) at 8 weeks, 6, and 12 months. | — |
