Biodegradable screw versus a press-fit bone plug fixation for hamstring anterior cruciate ligament reconstruction: a prospective randomized study.

Background: Press-fit fixation of a tendon graft has been advocated to achieve tendon-to-bone healing.

Hypothesis: Fixation of hamstring tendon grafts with a porous bone scaffold limits bone tunnel enlargement compared with a biodegradable interference screw fixation.

Study Design: Randomized controlled trial; Level of evidence, 1.
