Patent number: 11020246Abstract: A force and rotation sensing device can be suitable for measuring a force within a knee joint. A force sensor can measure a force exerted between opposing surfaces of a housing. A force display positioned on the housing can visually represent a value of the measured force, such as with a dual-sided light-emitting diode display that is visible from opposing sides of the housing. A first rotation sensor can measure a flexion/extension position of the housing. A flexion/extension display can visually represent a value of the measured flexion/extension position. In some examples, a zero button can set a reference orientation of the housing, so that the first rotation sensor can measure the flexion/extension position as a relative rotation with respect to the reference orientation. In some examples, circuitry can wirelessly transmit data corresponding to the value of the measured flexion/extension position.Type: GrantFiled: January 24, 2018Date of Patent: June 1, 2021Assignee: Zimmer, Inc.Inventors: Kenneth D.

Patent number: 11006992Abstract: The embodiments provide provides devices, instruments, and associated methods for treating joint pain. A joint is evaluated using magnetic resonance imaging to detect any defects in the subchondral bone. For example, using T2-weighted MRI images, bone marrow lesions or edemas can be identified, and using T1-weighted MRI images, associated regions of sclerotic bone adjacent to the bone marrow lesion can be identified. The treatment method may involve introducing a bone void filler material at the site to address the bone marrow lesion or edema, and/or drilling and inserting an implant to address the sclerotic bone, bone marrow lesion or edema, and insufficiency or stress fractures. An access path is mapped to a location in the subchondral region where the insufficiency fracture resides. The access path attempts to preserve an articular surface of the joint. A reinforcing member that stabilizes the insufficiency fracture is then implanted via the access path.Type: GrantFiled: December 21, 2018Date of Patent: May 18, 2021Assignee: ZIMMER KNEE CREATIONS, INC.Inventors: Peter F.
