Three-compartment knee prosthesis 3DKnee™

fixed-bearingcemented or non-cemented

The 3DKnee is a premium high flexion total knee replacement designed after a decade of research. The 3DKnee instills confidence through every step of the total knee replacement process, from the surgeon’s joint selection decision, to the surgical procedure and patient post-operative function. Over a decade of research confirmed that the ACL deficient total knee has very different kinematics from an ACL intact normal knee.1,2 The 3DKnee is based on data from insert retrievals, tibial plateau analysis, and fluoroscopic review (shown in Figures A and B) which concluded that an ACL deficient knee has a lateral rotational bias. With a ball and socket lateral condyle for rotation and a flatter medial condyle designed for translation, the 3DKnee is designed to allow ACL deficient TKA kinematics. The design has performed successfully in vivo with excellent Knee Society scores. Through every step of the 3DKnee procedure, surgeons have accurate guidance from the instrumentation and yet are allowed the freedom and flexibility to alter intra-operative plans as needed. M.I.K.A.™ (minimally invasive knee arthroplasty) or standard incision instruments are available and allow a surgeon to work confidently through the best incision possible for each patient.
