Anterior Cruciate Ligament Reconstruction by Using Bioabsorbable Femoral Cross Pins: MR Imaging Findings at Follow-up and Comparison with Clinical Findings

Abstract

Fracture and posterior transcortical breach of bioabsorbable femoral cross pins, commonly seen at follow-up MR imaging studies, do not correlate with clinical findings of joint instability or pain. Posteriorly angulated cross pins and posterior transcortical breach are significantly associated with cross-pin fractures.
