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.
Claims20
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,
- distracting the patient's knee joint while the knee joint is in extension;
- 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
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,
- distracting the patient's knee joint to establish a substantially rectangular gap between the patient's proximal tibia and distal femur;
- 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.
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,
- distracting the patient's knee joint to establish a substantially rectangular gap between the patient's proximal tibia and distal femur;
- 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.
