Arthroscopic Transosseous Suture-bridge Fixation for Anterior Cruciate Ligament Tibial Avulsion Fractures

Abstract

Few cases of tibial spine avulsion injuries occur in adolescents. An open or arthroscopic surgical approach is indicated for displaced and nonreducible fractures, but evidence for a gold standard is insufficient. Various arthroscopic techniques are available. Suture fixation is popular and shows good results. The proposed technique is a modified suture-bridge fixation using 2 high-strength sutures tied through 2 transosseous tunnels. This simple and low-cost technique avoids the potential complications of hardware fixation within a joint. It represents an arthroscopic treatment option for anterior cruciate ligament tibial avulsion injuries.
