Description

Zi Qiang Glen Liau and co-authors (2026) offer surgeons a formula that predicts the size of a knee graft before the first incision. The quadriceps tendon is gaining favor for rebuilding a torn anterior cruciate ligament, but harvesting it can weaken the thigh more than other graft choices, so size planning matters. A graft under ten millimeters risks failure. Until now, prediction from pre-surgery MRI used only rough cutoffs. The authors test a continuous method instead.

Their formula converts the tendon's MRI width into an estimated graft diameter, two times the square root of width over pi. They checked the estimate against the real grafts, within one millimeter counting as accurate, tested the old cutoff approach too, and measured whether two raters using the method agree. A reliable prediction lets the surgical team plan the harvest, or choose a different graft, before the patient is asleep.
