What it can tell you

That repair tissue is still measurably changing on quantitative MRI texture analysis between 3 and 24 months — the graft is not finished when the protocols end.

What it cannot

What that maturation means clinically, or what loading does to it. An imaging subcohort of 37 shows change is happening; it cannot prescribe anything.

Read it like a sceptic
Texture analysis is a research instrument, not a clinical standard; MACT and microfracture patients are pooled in the imaging set.

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.
