Specimens were mounted to a load frame that applied a 1000-N axial load. Joint contact pressures were measured using thin pressure sensors, and the peak and mean pressures were analyzed.

The addition of a root tear to the MTL tear state resulted in significantly more extrusion ( P = 0.001) and significant increases in medial compartment pressure ( P = .030) compared to the MTL tear state.
