title: Axial rotation of the prosthetically replaced knee.
abstract: Meniscal total knee replacement differs from total condylar designs in that it allows free axial rotation. This reduces torque forces on the tibial component and may help to prevent aseptic loosening. The amount of rotation occurring in patients with meniscal total knee replacement was an average range of 6 degrees. The average movement of the polyethylene 'menisci' is 3 mm.
