Slide 7: Pin placement
Pin placement Tibia Femur • Surgeon makes incision a minimum of 10 cm (approximately four • Patient knee should be flexed to >90 degrees to elongate quadriceps muscles fingerbreadths) inferior to the tibial tubercle and 10-15 mm medial to the tibial crest • Surgeon makes first incision approximately
Slide 8: Array placement
Array placement • A sterile staff member assembles the pelvic array adapter and 2-pin clamp • The clamp slides over the pins with the clamp against the top of the array stabilizer • The clamp’s screw should point away from the camera and the pelvic array adaptor’s screw away from the incision • The

Slide 10: CT-based planning
Know more. CT-based planning CT data is segmented to create a 3D model of the patient’s bony anatomy. The Mako Partial Knee application allows a surgeon to manipulate the unicompartmental implant on the patient’s virtual 3D anatomy during preoperative planning. MAKPKA-PRE-87_34429

Slide 14: Dynamic joint balancing
Know more. Dynamic joint balancing After assessing the patient’s ligament tension, gap analysis, limb alignment and cartilage transition zones, surgeon-controlled intraoperative adjustments can be made to the preoperative plan. Gap balancing Cartilage mapping Implant tracking MAKPKA-PRE-87_34429
Slide 15: Gap balancing
Gap balancing Poses of the leg at a given knee flexion are captured throughout the range of motion (minimum of 4 poses). Mako software uses the captured poses to produce a graph. After the poses are captured, the surgeon can make changes to the planned implants to balance the graph. MAKPKA-PRE-87_34
Slide 16: Cartilage mapping
Cartilage mapping Cartilage mapping helps ensure there is a smooth transition for the patella as it tracks from the trochlear grove onto the femoral component. Surgeon uses green probe to map the patient’s cartilage along the anterior tip of the femoral component. MAKPKA-PRE-87_34429
Slide 17: Implant tracking
Implant tracking The purpose of tracking is to confirm the femoral and tibial implants are tracking on the center of each other to avoid edge loading. Tracking points allow the surgeon to see where the center of the tibial component is tracking relative to the femoral implant throughout the range of
