  1. The normal group shows features similar to the control concerning behaviour timing. The earlier or later groups show earlier and later occurring times compared to the control group. The values represent the mean ± standard deviation. *Indicates the significant difference between the early and late groups (p < 0.05).
  2. MME medial meniscus extrusion, ΔMME the difference in medial meniscus extrusion between maximum and minimum.
