Pigs with scaffold-augmented ACL repairs had the same knee movement and stability tests as those with just stitches.
Scientific Claim
In Yucatan minipigs, ACL repair did not significantly affect terminal flexion, terminal extension, or Lachman test results between collagen scaffold-augmented and suture-only groups (terminal flexion p=0.685, terminal extension p=0.504, Lachman sign p=0.598).
Original Statement
“There was no significant treatment effect on terminal flexion (p=0.685) or terminal extension (p= 0.504; Table 1). There was no significant effect of treatment on the Lachman sign (p=0.598).”
