In pigs, adding a collagen scaffold to stitched ACL repairs didn't make the ligament stronger or stiffer than just stitching it.
Scientific Claim
In Yucatan minipigs, collagen scaffold augmentation of ACL suture repair did not significantly improve yield load (mean difference 44.7 N, p=0.66) or linear stiffness (mean difference 5.8 N/mm, p=0.74) compared to suture repair alone.
Original Statement
“There was no significant difference in the yield load, maximum failure load, linear stiffness, displacement to yield, displacement to failure, or displacement to 5N of tensile load between the two groups (Table 2).”

Assessment Explanation
The claim reports specific numerical differences and p-values from the study without overgeneralizing. 'Did not significantly improve' is accurate for the observed data.
Evidence from Studies

Collagen scaffold supplementation does not improve the functional properties of the repaired anterior cruciate ligament
