What it cannot
Anything cartilage-specific, and not much with confidence anywhere: the authors graded their own pooled evidence as weak, with 70% of studies at high risk of bias.

Read it like a sceptic
Weak evidence about a real phenomenon — the site cites it for 'this dimension exists', not for any number.
Population
ACL injury — a different population from MACI itself. Wherever this source appears, that flag appears with it.
Selection policy
Sources enter the registry through docs/research — the evidence table records design, population, and size for every entry, and pages cannot cite anything outside it.
