Comparable Tibial Tunnel Widening despite Compound Differences of Bioabsorbable Interference Screws in Anterior Cruciate Ligament Reconstruction: a Retrospective Study

SUMMARY Purpose. To evaluate the effect of β-tricalcium phosphate (BCP) concentration in bioabsorbable interference screws on tibial tunnel widening after hamstring anterior cruciate ligament reconstruction. Methods. A total of 37 patients with a mean follow-up of 4.6 years were included for analysis. Bioabsorbable interference screws containing 60% BCP and 40% poly-L,Dlactic acid (PLDLA) (60BCP group) or bioabsorbable interference screws … Continued
