View Edit Delete	OPT-9	In one aspect the balance indicator connects to the superior plate, the superior plate that includes a pivot plate and a support plate and the balance indicator includes a hinge that includes a pin connected to the pivot plate such that a force applied to the pivot plate can rotate the pivot plate about the pin. The support plate couples to the separator such that actuation of the separator moves the support plate vertically relative to the inferior plate. The pin may include a cylindrical structure that has a longitudinal axis, a proximal end, a distal end, and a middle. The proximal end may connect to a balance gauge and the distal end comprises a pivot for the balance indicator. The pivot may be aligned with the longitudinal axis. In one embodiment, the proximal end may include a first D-shaped cross-section, the distal end may include at least one keyed section, and the middle may include a second D-shaped cross-section having a flat part of the second D-shaped cross-section offset 90 degrees from a flat part of the first D-shaped cross-section. The distal end serves as a pivot for the hinge.	10	Added by DJM 2 2021	2/17/21, 12:00 AM

In one embodiment, the follower slidably contacts the contacting surface. The cam may include a radial cam having a central axis and the contacting surface be a circumference of the radial cam about the central axis.	11	Added by DJM 2 2021	2/17/21, 12:00 AM

View Edit Delete	OPT-9	The various apparatus, devices, systems, and/or methods of the present disclosure have been developed in response to the present state of the art, and in particular, in response to the problems and needs in the art that have not yet been fully solved by currently available arthroplasty balance gauges or arthroplasty gap gauges. The apparatus, devices, systems, and/or methods of the present disclosure may provide an arthroplasty balance and gap gauge in a single device that remedy shortcomings of prior art separate arthroplasty balance gauges and/or arthroplasty gap gauges.	3	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	Arthroplasty procedures can be used to relieve pain in or restore function of a joint due to conditions such as osteoarthritis, rheumatoid arthritis, or other joint conditions through minimally invasive or invasive surgery. An arthroplasty procedure can be performed on any joint and may include a partial or total joint replacement with a replacement prosthesis or prostheses. During an arthroplasty procedure, a surgeon may want to measure a size of an opening between two bones of the joint. In addition, the surgeon may also want to measure a balance of the joint in addition to a size of an opening (referred to as a gap) between two bones of the joint. For example, during partial or total knee replacement (TKR) arthroplasty, a surgeon may desire to gauge or measure a displacement between two bones of the joint and a balance of the joint. Taking such measurements during minimally invasive or invasive arthroplasty can be a challenge given forces applied to the joint by ligaments and other soft tissue of or around the joint. Accordingly, a need exists for improved systems and methods to measure the gap and/or angulation between bones in the course of an arthroplasty procedure.	2	Added by DJM 2 2021	2/17/21, 12:00 AM
