Question: A 23-year-old boy, who makes a jump while playing basketball, falls on his right lower limb with his knee in hyperextension, applying a sharp turn to his knee while keeping his foot fixed on the ground. The patient, perceives a snap and sharp pain in his knee, unable to continue playing. Note feeling of instability when performing the support of said extremity. On clinical examination, intense articular effusion is seen, so arthrocentesis is performed, which shows an important acute hemarthrosis without the presence of droplets of fat supernatanting in the extracted fluid. The mobility of the knee is free and the Lachman maneuver is positive. What is the diagnostic suspicion? 
 Options:  <0> Break in cube handle of the inner meniscus. <1> Isolated rupture of the lateral collateral ligament. <2> Fracture by tearing of the anterior tibial spine. <3> Unicondylar fracture of the medial condyle. <4> Rupture of the anterior cruciate ligament
