Okoroha KR et al. Effects of a Perioperative Blood Flow Restriction Therapy Program… OJSM 2023
What it can tell you
That perioperative blood-flow-restriction training improved quadriceps outcomes in a randomized trial — in ACL reconstruction patients.
What it cannot
Anything about MACI. Different operation, different healing tissue, different loading constraints. On this site it appears only with the different-surgery flag, and the honest framing is a question for your PT, not a prescription.

Read it like a sceptic
n=46, single centre.
BFR protocols vary widely (cuff pressure, load, volume); this tests one of them.
Population
ACL reconstruction — 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.
