Osteosynthesis with Arthroscopy of a Nonunited Tibial Anterior Cruciate Ligament Avulsion Fracture 30 Years after Injury

Figure 2

(a) Preoperative STIR image of MRI showing poor delineation of the ACL. (b) Arthroscopic image of the ununited fracture area. The bone fragment was displaced. (c) Arthroscopic image of the fracture bed. The fracture bed was freshened using a 4.5 mm arthroscopic shaver and a bipolar electrode. (d) Arthroscopic image of the fixation. The bone fragment was fixed via screw fixation. STIR: short T-inversion recovery; MRI: magnetic resonance imaging; ACL: anterior cruciate ligament; BF: bone fragment; FB: fracture bed.
