Abstract:
Anterior cruciate ligament tears are among the most frequent knee injuries. Surgical treatment is mandatory in active athletes to prevent meniscal tears and early joint degenerative changes. Anterior cruciate ligament arthroscopic reconstruction (ACLAR) is considered the preferred procedure, allowing a successful functional restoration and a prompt return to sports practice. Postsurgical complications are infrequent and are mainly assessed clinically and by magnetic resonance imaging. Although ultrasound can only evaluate the outer aspect of the knee, it can detect several ACLAR complications. The aim of this pictorial essay is to present the ultrasound appearances of a wide spectrum of ACLAR complications.
