Total Knee Arthroplasty
TKA smart – simple, mature, accurate, reliable, time-saving
The continuous improvement of the software for navigated TKA is closely designed in partnership with OrthoPilot® users.
TKA smart is designed for performing quick, but safe TKA in at least equal time as conventional technique focusing on the mechanical axis, not soft tissue management.
TKA smart Features
- Tibia first and femur first option
- Supports all our implants: Columbus®, e.motion®, e.motion® IQ and Vega System® IQ
- Supports standard, MIOS and IQ-instruments
- Is available for active as well as passive technology
- The camera can be positioned either on the ipsilateral (same side) or as usual on the contralateral (opposite side)
Software Elements
Kinematic data acquisition
The kinematic acquisition is the guarantee and therefore an important factor for an optimal surgical result. To compute the mechanical centers of the hip, knee and ankle joints, a camera tracks the movement of the markers fixed to the bone.
Palpation of anatomic landmarks
In addition of the kinematic acquisitions, anatomic bone landmarks are palpated. Anatomic landmarks are prominent structures, such as the anterior cortex. Due to the redundancy the result is further optimized.
Tibial resection
The position of the femoral resection can be adjusted with the cutting block according to:
- Varus/valgus
- Anterior/posterior tibial slope
- Medial and lateral height of resection
After the resection, the position and alignment of the final cutting plane is confirmed with a measuring plate.
Femoral resection planning
This feature allows the prospective planning of the resection considering the size and positioning of the femoral component. This step precedes the actual execution of the femoral cuts. It allows simulating the ideal outcome for the patient in the given situation.
Femoral resection and rotation
The position of the cutting block can be adjusted, according to:
- Varus/valgus
- Anterior/posterior slope
- Distal resection height
- After the resection, the position and alignment of the final cutting plane is validated.
Adjustment of femoral rotation according to:
- Posterior condyles
- Epicondyles
- Whiteside line
