What it can tell you

The one imaging finding in this literature aimed at the compartment this site's owner has: in retropatellar transplantation, subchondral changes visible at three months were the best early predictor (accuracy 0.76) of a meaningful IKDC improvement at twelve. An early MRI is otherwise mostly reassurance; this is a reason to read one.

What it cannot

What to do about it. Nothing here tests an intervention — a worrying three-month subchondral appearance has no studied response, and the finding is prognostic rather than actionable. Nor does it extend past twelve months.

Everything on this site that leans on E22 — 0 claims

Nothing cites this source yet — it is part of the vetted evidence base for content still being written.

Read it like a sceptic
n=38, single centre, and 0.76 accuracy means roughly one patient in four is called wrong.
Reading it the other way round is the temptation to resist: this does not license treating a clean three-month MRI as permission to progress faster.
