Table 2 shows results from manual examination prior to testing the subjects with the new device. Data include manual Lachman, instrumented Lachman with a Rolimeter measurement device, the pivot shift test, and manual dial test. Manual dial test was tested at 30° and 90° and the data represent results for internal and external rotation. All subjects tested the same bilaterally.
