CONCEPT

MyKnee UNI is a patient-specific cutting block dedicated to partial knee replacement, allowing the surgeon to realize his pre-operative 3D planning, based on CT or MRI images of the patient’s knee.

This innovative concept combines different features giving potential benefits to both the surgeon and the patient.

Slotted cutting block, not just a pin positioner
Sagittal cut marked with a pin hole
Transverse and sagittal resection levels marked on the bone model
Intra-operative alignment check thanks to the extra-medullary drop rod connection
Accurate estimation of the femoral size, crucial for a successful PKR
Good results for accuracy of tibial component varus/valgus positioning, tibial slope and intra-/extra-rotation ^[1]

PRODUCT RANGE

MyKnee UNI

The MyKnee UNI tool is exclusively dedicated to GMK UNI implants.

The MyKnee UNI Shim Technique tool is dedicated to the shim technique, which can be used for both GMK UNI and MOTO Medial implants.

MyKnee PPS UNI

MyKnee PPS UNI is a CT-Based, patient specific, tibial pin positioner block, that allows the surgeon to position the tibia metal guide according to the preoperative planning, in order to perform a tibial conservative resection.

MyKnee PPS UNI preoperative planning offers an evaluation of tibia slope, tibia varus-valgus, tibia cut height and vertical cut orientation. The tibial block is used to position the metal shim tibial cutting guide in accordance with the resection parameters set during the preoperative planning. It is always possible to intraoperatively check the tibial varus/valgus with the alignment rod before the initial tibial resection.

The MyKnee PPS UNI tool is exclusively dedicated to MOTO Medial implants.
