Anterior Posterior (AP) translations of lateral femoral condyles during activity of walking up a ramp. Data represents the motion of a specific part of the femur bone (in this case lateral femoral condyle) during the specified activity (in this case a ramp up). The kinematics (motion) is measured from the beginning of the activity to the end of the activity. Positive represents anterior motion of the femur, and negative represents posterior rollback of the femur. Data is only collected at a single time point and therefore refers to the motion of the femur bone during a specific activity at a single point in time.

Anterior Posterior (AP) translations of medial femoral condyles during activity of walking up a ramp. Data represents the motion of a specific part of the femur bone (in this case medial femoral condyle) during the specified activity (in this case a ramp up). The kinematics (motion) is measured from the beginning of the activity to the end of the activity. Positive represents anterior motion of the femur, and negative represents posterior rollback of the femur. Data is only collected at a single time point and therefore refers to the motion of the femur bone during a specific activity at a single point in time.

Femorotibial axial rotation during activity of walking up a ramp. Data represents the motion of a specific part of the femur bone (in this case femorotibial axial rotation) during the specified activity (in this case a ramp up). The kinematics (motion) is measured from the beginning of the activity to the end of the activity. Positive represents external rotation of the femur, and negative represents internal rotation of the femur. Data is only collected at a single time point and therefore refers to the motion of the femur bone during a specific activity at a single point in time.

Anterior Posterior (AP) translations of lateral femoral condyles during activity of walking down a ramp. Data represents the motion of a specific part of the femur bone (in this case lateral femoral condyle) during the specified activity (in this case a ramp down). The kinematics (motion) is measured from the beginning of the activity to the end of the activity. Positive represents anterior motion of the femur, and negative represents posterior rollback of the femur. Data is only collected at a single time point and therefore refers to the motion of the femur bone during a specific activity at a single point in time.

Femorotibial axial rotation during activity of walking down a ramp. Data represents the motion of a specific part of the femur bone (in this case femorotibial axial rotation) during the specified activity (in this case a ramp down). The kinematics (motion) is measured from the beginning of the activity to the end of the activity. Positive represents external rotation of the femur, and negative represents internal rotation of the femur. Data is only collected at a single time point and therefore refers to the motion of the femur bone during a specific activity at a single point in time.

Anterior Posterior (AP) translations of lateral femoral condyles during a deep knee bend. Data represents the motion of a specific part of the femur bone (in this case lateral femoral condyle) during the specified activity (in this case a deep knee bend). The kinematics (motion) is measured from the beginning of the activity to the end of the activity. Positive represents anterior motion of the femur, and negative represents posterior rollback of the femur. Data is only collected at a single time point and therefore refers to the motion of the femur bone during a specific activity at a single point in time.

Femorotibial axial rotation during a deep knee bend. Data represents the motion of a specific part of the femur bone (in this case femorotibial axial rotation) during the specified activity (in this case a deep knee bend). The kinematics (motion) is measured from the beginning of the activity to the end of the activity. Positive represents external rotation of the femur, and negative represents internal rotation of the femur. Data is only collected at a single time point and therefore refers to the motion of the femur bone during a specific activity at a single point in time.

Maximum weight-bearing femorotibial flexion during a deep knee bend. Data represents the motion of a specific part of the femur bone (in this case femorotibial range of motion) during the specified activity (in this case a deep knee bend). The kinematics (motion) is measured from the beginning of the activity to the end of the activity. Positive values are the only possible values in this case, representing the magnitude of weight-bearing flexion. Data is only collected at a single time point and therefore refers to the motion of the femur bone during a specific activity at a single point in time.
