A Mechanically Secured Plastic Patellar Prosthesis - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240024118 titled 'A Mechanically Secured Plastic Patellar Prosthesis

Simplified Explanation

The abstract describes a plastic patellar prosthesis that has orienting pins with projections that are larger in diameter than the patellar hole. This diametrical interference causes the projections to deform and secure the prosthesis to the resurfaced patella as the cement cures, eliminating the need for a patellar clamp.

  • The plastic patellar prosthesis has orienting pins with projections.
  • The projections have a larger diameter than the patellar hole.
  • The diametrical interference causes the projections to deform.
  • The deformed projections mechanically secure the prosthesis to the resurfaced patella.
  • The prosthesis does not require a patellar clamp to hold it in place.

Potential applications of this technology:

  • Knee replacement surgeries
  • Orthopedic procedures involving patellar resurfacing

Problems solved by this technology:

  • Eliminates the need for a patellar clamp, simplifying the surgical procedure
  • Provides mechanical security without relying solely on cement curing

Benefits of this technology:

  • Simplifies the surgical procedure by eliminating the need for additional tools
  • Improves the mechanical stability of the patellar prosthesis
  • Reduces the risk of dislocation or loosening of the prosthesis


Original Abstract Submitted

a plastic patellar prosthesis having a plurality of orienting pins, each pin having one or more projections that define a maximum diameter greater than the diameter of the patellar hole into which the orienting pin is inserted. the diametrical interference causes the projections to deform and thereby mechanically secure the patellar prosthesis to the resurfaced patella as the cement cures without the need for a patellar clamp to hold the prosthesis in place.
