Question 2

What knee test is more sensitive than the Lachman, anterior draw and Pivot shift test in acute partial tears?


  • The Lever or Lelli test
  • According to the inventors study, Lelli, all tests were nearly 100 % sensitive for patients with chronic, complete tears of the ACL. However, for patients with acute, partial tears, the sensitivity was much lower for the Lachman test (0.42), Anterior Drawer test (0.29), and Pivot Shift test (0.11), but not the Lever Sign test (1.00) [Reference]

Question 3

Question 4

A forensic pathologist examines the body of a recently deceased man. The pathologist notes a drop of seminal fluid at the tip of the dead man’s penis. Does this indicate that the man was engaged in sexual activity just before death?


  • No.
  • The seminal vesicles may contract as part of rigor mortis, resulting in the expulsion of seminal fluid.
  • Rigor mortis is the post-mortem contraction of muscle fibers due to the locking of actin-myosin filaments when ATP is depleted. [Reference]
