Adjustable testing apparatus for an orthopaedic specimen such as a knee implant prosthesis

A testing apparatus for exposing an associated specimen to movement along multiple axes, the testing apparatus comprising:

• a first test chamber dimensioned to receive the associated specimen;
• a first device operatively connected to the test chamber to impose a first, rotational movement on the associated specimen;
• a second device operatively connected to the test chamber to impose a second, rotational movement different than the first movement on the associated specimen;
• a third device operatively connected to the test chamber to impose a linear translation on the associated specimen;
• a fourth device operatively connected to the test chamber to impose a dynamic force on the associated specimen;
• a drive mechanism operatively connected to the first, second, third, and fourth devices so that at least one of the first, second, third and fourth devices is driven by the drive mechanism and the at least one device delivers a force on the test chamber;
• and
• at least one of the first, second, third, and fourth devices includes an adjustment mechanism to modify at least one of the devices.
