In Schmutterer 2024 et al., on stifle flexion angle effects, how did the center of force shift during increased stifle flexion?
A. Shifted cranially
B. Shifted medially
C. Shifted caudally
D. No directional shift
E. Shifted proximally
Answer: Shifted caudally
Explanation: Center of force moved significantly more caudal with increased flexion, especially at the medial meniscus (p = 0.003)
In Schmutterer 2024 et al., what was the observed peak pressure in the lateral meniscus at 125° flexion?
A. 0.9 MPa
B. 1.0 MPa
C. 1.2 MPa
D. 1.5 MPa
E. 1.3 MPa
Answer: 1.2 MPa
Explanation: Lateral meniscus peak pressure was 1.2 MPa at 125°, higher than at 145° (1.0 MPa), p = 0.049
In Schmutterer 2024 et al., what was the trend in mean pressure on the medial meniscus across all angles tested?
A. Increased with extension
B. Decreased with extension
C. Remained constant
D. Varied unpredictably
E. Decreased then increased
Answer: Remained constant
Explanation: Mean pressure on the medial meniscus remained relatively constant across 125° to 145° flexion
In Schmutterer 2024 et al., on stifle flexion angle effects, at which angle was the contact force ratio (CFR) significantly lowest?
A. 125°
B. 135°
C. 145°
D. All angles had equal CFR
E. 135° and 145°
Answer: 145°
Explanation: CFR was significantly lower at 145° compared to both 125° and 135° flexion angles (p < 0.001)
In Schmutterer 2024 et al., what was concluded regarding femorotibial kinematics when changing flexion angles?
A. Significant change with flexion
B. Significant increase in femoral rollback
C. No significant kinematic change
D. Increased femoral torsion during load
E. Increased internal rotation only
Answer: No significant kinematic change
Explanation: Flexion angle altered load metrics but not femorotibial kinematics in this setup
