Magnetic Knee Prosthesis System
Summary
USPTO published patent application US20260090892A1 filed by inventor James M. Jackson for a magnetic knee prosthesis system using repulsive magnetic forces between femoral and tibial components to potentially improve joint function. The application, filed December 9, 2025 under Application No. 19414239, covers A61F classifications related to orthopedic knee implants.
What changed
USPTO published patent application US20260090892A1 disclosing a magnetic knee prosthesis comprising a femoral component with a first magnetic portion and a tibial component with a second magnetic portion, where like magnetic poles create repulsive force to reduce joint friction. The magnetic portions are positioned to avoid interrupting articulating condyle or bearing surfaces. The application claims priority to Application No. 19414239 and falls under CPC classifications A61F 2/3836, A61F 2/3859, A61F 2/3868, and A61F 2/389 among others.
Medical device manufacturers developing orthopedic implants should review the patent claims to assess potential freedom-to-operate implications or licensing opportunities. Healthcare providers and patients involved in knee replacement decisions should note this as a developing technology. No immediate compliance actions or deadlines apply to this patent publication; standard intellectual property review processes apply for manufacturers considering similar designs.

Abstract
An orthopedic knee prosthesis includes a femoral component, a tibial bearing, a tibial component, a first magnetic portion associated with the femoral component and including a first pole having a first pole polarity the first magnetic portion not physically interrupting any articulating portion of the curved medial condyle surface or curved lateral condyle surface, and a second magnetic portion associated with one or both of the tibial bearing and/or the tibial component and including a second pole having a second pole polarity, the second pole polarity the same as the first pole polarity, the second magnetic portion not physically interrupting any articulating portion of the concave medial bearing surface or concave lateral bearing surface, wherein the first pole and the second pole are in sufficient proximity to each other such that a magnetic repulsive force is present therebetween.
