#CMT# #/CMT# 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). #CMT#USE : #/CMT# Unicompartmental prosthesis for knee for orthopedic surgery. #CMT#ADVANTAGE : #/CMT# The prosthesis permits the surgeon to install a mobile insert and fixed insert in a simple manner, while permitting to modify operation strategy based on observation made on operation table by surgeon. The geometry of the prosthesis is adapted to the anatomical characteristics of the articulation. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an outer side of a femoral element of a unicompartmental knee prosthesis. R1, R2 : Radius 1 : Femoral element 2 : Outer surface 3 : Anterior part 4 : Posterior part. |
