Which of the following is the SAFEST test to be performed in a patient with acutely injured knee joint -
Lachmann test
Pivot shift test
McMurray's test
Apley's grinding test
Pivot shift test and anterior drawer test require flexion of the knee joint, which cannot be possible in acutely injured knee.
Lachman's test is done in 15-30° of flexion, therefore can be performed in acutely injured knee.
