Unicompartmental knee prosthesis for orthopedic surgery, has profile with has radius , femoral element with convex outer surface having transversal curvature whose profile is circle portion with radius equal to radius of sagittal part

摘要

The prosthesis has a femoral element (1) with an artificial condyle and a tibial element. The element (1) has a convex outer surface (2) with an anterior part (3) whose sagittal profile is circular with a radius (R1), and a posterior part (4) arranged in continuity with the anterior part (3). The profile is circular with another radius (R2), where the surface (2) has transversal curvature whose profile is a circle portion with another radius equal to the radius (R1).
