The question asks about the gait abnormlity expected for this patient. Steppage and equine gait are similar with drop foot resulting from peroneal nerve injury or neurological disorder, these 2 choice are wrong for this patient. The first choice of trendlenburg gait is aslo wrong because this gait happens if there is weakness of hip abductors. The choice of antalgic gait is the right one because in this type of gait abnormality there is pain in the lower limb and the patient avoids as possible the stance phase or make it shorter time because of the pain. so, the good choice for this question is number 2.
