Method for performing an orthopaedic surgical procedure
First Claim
1. A method for performing an orthopaedic surgical procedure on a knee joint of a patient, the method comprising:
- resecting a proximal end of a patient'"'"'s tibia to create a resected surface of the patient'"'"'s tibia;
positioning a tibial paddle of a sensor module on the resected surface of the patient'"'"'s tibia, the tibial paddle including a sensor array and having an upper tibial paddle housing with a substantially flat surface,distracting the patient'"'"'s knee joint while the knee joint is in extension, wherein distracting the patient'"'"'s knee joint comprises positioning a joint distractor in the patient'"'"'s knee joint such that a medial tibial paddle of the joint distractor and a lateral tibial paddle of the joint distractor each contacts the upper tibial paddle housing of the sensor module;
monitoring a display of the sensor module, the display providing a visual indication of the medial-lateral joint force balance of the patient'"'"'s knee joint; and
performing a balancing procedure to adjust the medial-lateral balance as indicated by the display of the sensor module.

Abstract
A method for performing an orthopaedic surgical procedure on a knee joint of a patient includes resecting a proximal end of a patient'"'"'s tibia to create a resected surface of the patient'"'"'s tibia and positioning a tibial paddle of a sensor module on the proximal end of the patient'"'"'s tibia. The tibial paddle includes a sensor array generating sensor signals indicative of the joint force of the patient'"'"'s knee joint. The method also includes performing a number of orthopaedic surgical steps while monitoring a display of the sensor module that provides a visual indication of the medial-lateral balance of the joint force of the patient'"'"'s knee joint.

11. A method for performing an orthopaedic surgical procedure on a knee joint of a patient, the method comprising:
-
resecting a proximal end of a patient'"'"'s tibia to create a resected surface of the patient'"'"'s tibia; positioning a tibial paddle of a sensor module on the resected surface of the patient'"'"'s tibia, the tibial paddle including a sensor array positioned therein and having an upper tibial paddle housing with a substantially flat surface, distracting the patient'"'"'s knee joint to establish a generally rectangular joint gap between the patient'"'"'s proximal tibia and a resected distal end of the patient'"'"'s femur such that the resected surface of the patient'"'"'s tibia is approximately parallel with the resected distal end of the patient'"'"'s femur, wherein distracting the patient'"'"'s knee joint comprises positioning a joint distractor in the patient'"'"'s knee joint such that a medial tibial paddle of the joint distractor and a lateral tibial paddle of the joint distractor each contacts the upper tibial paddle housing of the sensor module; monitoring a visual indication of the relative balance of a medial joint force and a lateral joint force of the patient'"'"'s knee joint displayed on the display of the sensor module; and performing a balancing procedure on the patient'"'"'s knee joint until the medial joint force and the lateral joint force are within a first predetermined percentage of each other as indicated on the visual indication displayed on the display module. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method for performing an orthopaedic surgical procedure on a knee joint of a patient, the method comprising:
-
positioning a tibial paddle of a sensor module on a resected proximal end of a patient'"'"'s tibia, the tibial paddle including a sensor array positioned therein and having an upper tibial paddle housing with a substantially flat surface, distracting the patient'"'"'s knee joint to establish a generally rectangular joint gap between the patient'"'"'s proximal tibia and a resected distal end of the patient'"'"'s femur such that the resected proximal end of the patient'"'"'s tibia is approximately parallel with the resected distal end of the patient'"'"'s femur, wherein distracting the patient'"'"'s knee joint comprises positioning a joint distractor in the patient'"'"'s knee joint such that a medial tibial paddle of the joint distractor and a lateral tibial paddle of the joint distractor each contacts the upper tibial paddle housing of the sensor module; monitoring a plurality of light emitting diodes located on the sensor module, the plurality of light emitting diodes being illuminated in a pattern to provide a visual indication of the relative balance of a medial joint force and a lateral joint force of the patient'"'"'s knee joint displayed on the display of the sensor module; and performing a ligament release procedure on the patient'"'"'s knee joint until the medial joint force and the lateral joint force are within a first predetermined percentage of each other as indicated by the plurality of light emitting diodes.
