Examination of the tibiofemoral joint should be performed in a stepwise manner. In general, one performs stability testing for anterior translation, posterior translation, medial sided injuries, and posterolateral injuries in a uniform and stepwise manner to determine if there are any associated instabilities. It is important when performing this testing to compare any motion increases to the normal contralateral knee because there is a relative amount of physiologic differences between patients, so one should always compare knee motion between sides when possible.
