Abstract
A knee brace includes an upper support assembly pivotally attached to a lower support assembly. A magnetic assembly secures the upper and lower support assemblies to a leg of a wearer above and below the knee joint, respectively. The upper and lower support assemblies each include a pair of support elements engageable with the medial and lateral sides of a wearer's leg. A pair of polycentric hinge members pivotally connect the upper support elements to respective lower support elements. Flexible padded bands attached between the pairs of upper and lower support elements engage the thigh and calf of the leg. Stop members associated with the polycentric hinge members and support elements restrict extension of the wearer's leg. The magnetic assembly includes implanted magnets mounted directly to each of the medial and lateral sides of the femur and tibia beneath the tissue of the leg. Exterior magnets attached to the support elements cooperate with the implanted magnets to secure the knee brace to the leg of a wearer.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
