View Edit Delete	OPT-9	The opening in the superior body 136 can be sized to accept the shaft 140 and the spring 142 coiled around the outside of the shaft 140. The spring 142 may contact the superior body 136 and the head 144. The shaft 140 and spring 142 cooperated to retain the superior body 136 connected to the inferior body 138. In one embodiment once assembled in the gap gauge 100, the spring 142 may be biased against the head 144 and the superior body 136. The spring 142 can bias the superior body 136 in opposition to movement of the superior plate 118 away from the inferior plate 120.	63	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	In one embodiment, the shaft 140 may fit within an opening in the superior body 136 and pass through the superior body 136 to engage the inferior body 138. In certain embodiments, the shaft 140 can include threads on the outside of one end of the shaft 140. The threads of the shaft 140 may engage threads of an opening in the inferior body 138 to connect the shaft 140 to the inferior body 138. The shaft 140 may include a head 144 on one end opposite an end that includes the threads.	62	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	The shaft 140 may couple or connect the superior body 136 to the inferior body 138. The shaft 140 may slidably couple with the superior body 136 to the inferior body 138. The slidable coupling between the shaft 140, the superior body 136, and the inferior body 138 permits adjustment of the displacement 128.	61	Added by DJM 2 2021	2/17/21, 12:00 AM

View Edit Delete	OPT-9	In another embodiment, adjusting the tension may also include releasing one or more of the medial collateral ligament and the lateral collateral ligament while the gap gauge remains between the femur and the tibia and remains actuated.	15	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	In one aspect, the method may also include adjusting a tension applied to the femur and the tibia by one or more of a medial collateral ligament and a lateral collateral ligament, and reading the balance indicator of the gap gauge to obtain an adjusted balance status between the femur and the tibia in response to adjusting the tension.	14	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	One general aspect of the present disclosure can include a method for measuring a gap between a femur and a tibia of a patient. The method may include, inserting a first plate and a second plate of a gap gauge between the femur and the tibia, actuating the first plate and the second plate apart such that the first plate is in contact with a resected surface of the femur and the second plate is in contact with a resected surface of the tibia, reading a separation indicator of the gap gauge to obtain a displacement between the femur and the tibia, and reading a balance indicator of the gap gauge to obtain a balance status between the femur and the tibia.	13	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	In one aspect, the gap gauge may include a balance gauge coupled to the balance indicator. The balance gauge may include a dial having marks positioned on a face to indicate a measure of the orientation of the superior plate relative to the inferior plate. The balance gauge may also include a needle connected to the balance indicator such that rotation of one of the superior plate and the inferior plate about an anterior-posterior axis of the patient moves the needle to point toward a mark on the face of the dial that reflects the orientation.	12	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	In one aspect, the gap gauge further includes a handle connected to the inferior body, a separation indicator coupled to the separator and configured to indicate the displacement, a lock-out mechanism connected to the superior body and configured to prevent rotation of the superior plate, or a part of the superior plate, connected to the balance indicator, and a spring coupled to the shaft that biases one of the superior body and the inferior body in opposition to movement of the superior plate away from the inferior plate. The separator may include a driver, a cam connected to the inferior body by way of the driver, the cam includes a contacting surface, and a follower connected to the superior body and biased and configured to contact the contacting surface of the cam such that rotation of the cam adjusts the displacement. 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	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

The gauge may also include a shaft along which at least one of the superior body and the inferior body is slidably coupled to permit adjustment of the displacement, a separator connected to the superior body and the inferior body to adjust the displacement, and a balance indicator connected to one of the superior plate and the inferior plate and configured to indicate an orientation of the superior plate relative to the inferior plate.	9	Added by DJM 2 2021	2/17/21, 12:00 AM
