In Scharpf 2024 et al., what type of analysis was used to assess limb loading recovery over time?
A. Visual lameness scoring only
B. Pressure mat analysis with subjective scores
C. Force plate analysis at walk and trot
D. Quantitative force plate gait analysis at walk only
E. Owner questionnaires and radiographs
Answer: Quantitative force plate gait analysis at walk only
Explanation: Force plate parameters (FZ, FY+, FY-, impulses, and SIs) were recorded at walk pre- and post-operatively at 4, 12, and 26 weeks:contentReference[oaicite:4]{index=4}
In Scharpf 2024 et al., which statement best reflects the authors' conclusion on subtotal coronoidectomy?
A. It fully restores joint loading by 12 weeks
B. It improves force metrics but braking deficits persist
C. It is most effective when paired with ACP
D. It delays osteoarthritis progression long-term
E. It is superior to non-surgical management
Answer: It improves force metrics but braking deficits persist
Explanation: Authors concluded that despite improvement in vertical and propulsive forces, braking forces and SIs remained impaired at 26 weeks:contentReference[oaicite:5]{index=5}
In Scharpf 2024 et al., on arthroscopic MCD treatment, which ground reaction force parameter did **not** normalize by 26 weeks?
A. Maximum vertical force (FZmax)
B. Propulsive force (FY-)
C. Braking force (FY+)
D. Impulse of vertical force (IZ)
E. Symmetry index of propulsive impulse (SI IY-)
Answer: Braking force (FY+)
Explanation: Braking force (FY+) and related impulses remained subnormal at 26 weeks, despite improvement in other GRF metrics:contentReference[oaicite:1]{index=1}
In Scharpf 2024 et al., what symmetry index (SI) threshold was considered indicative of normal limb loading?
A. 0.75
B. 0.80
C. 0.85
D. 0.90
E. 1.00
Answer: 0.90
Explanation: A symmetry index (SI) ≥ 0.9 was defined as normal for limb loading across all force parameters:contentReference[oaicite:3]{index=3}
In Scharpf 2024 et al., what was the effect of autologous conditioned plasma (ACP) compared to placebo on postoperative outcome?
A. ACP significantly improved all force parameters
B. ACP improved braking but not vertical forces
C. ACP reduced lameness on visual scoring only
D. ACP had no statistically significant effect at any time point
E. ACP delayed recovery initially but improved long-term outcomes
Answer: ACP had no statistically significant effect at any time point
Explanation: No differences in vertical, braking, or propulsive force or symmetry indices were observed between ACP and placebo groups throughout the study:contentReference[oaicite:2]{index=2}
