Right knee in 90° of flexion viewed from anterolateral portal. (A) Lavage is performed to evacuate any hemarthrosis or loose chondral or osteochondral fragments with debridement of the fat pad to improve visualization. A probe is introduced from the anteromedial portal and under the eminence fragment. (ACL, anterior cruciate ligament; frx, fracture.) (B) Trial reduction is performed with the probe with the knee in 90° of flexion; the fracture (frx) is then reduced by slowly extending the knee until reaching 40°.
