The custom cutting guides oneFIT Total Knee PSI are designed to uniquely fit the patient’s anatomy. They are designed to reproduce the parameters of preoperative planning in terms of femoral and tibial resection levels, 4-in-1 guide positioning holes and tibial implant holes.

The knee kit includes a femoral and tibial guide and associated bone models.

The guides and phantoms are manufactured using precise 3D SLS (Selective Laser Sintering) printing technology in polyamide (PA 2200), a biocompatible and autoclavable material.
