AVON Patello-Femoral

AVON Femoral Components

  • Cobalt chrome with 4 pegs (4mm x 8mm) for fixation (Superior peg on the small component is 4mm x 6.5mm)
  • Broad surface allows free patella movement in extension
  • Patella contact maintained up to 100 degrees of flexion1-5
  • Can be translated laterally (1mm-2mm) to the intercondylar mid-line and placed in 3-6 degrees of external rotation to reduce lateral overload
  • Cemented fixation
