Medacta’s core philosophy is based on the belief that innovation is the key to success. This leads to a constant effort towards the development of cutting edge solutions for Orthopaedics. MyKnee is a patient-specific cutting block, 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 to the patient.
Accurate implant positioning.[1-9]
No intramedullary canal violation.[10-12]
Up to 60% reduction of surgical steps for bone resection and related time.[13]
Potential increase of the number of cases per session.[14]
Up to 66% reduction of time and cost in washing, assembling and sterilization procedures.[13-15]
Interactive 3D web planning.
All these features translate in clinical and economic advantages, with the patient-matched technology itself resulting in a potential marketing tool to promote the surgeon and the clinic.
Based on individual patient‘s anatomy, the MyKnee cutting blocks are manufactured to accurately match the surgeon‘s preoperative planning and feature:
Since the surgical technique does not require intramedullary canal violation, the risks of embolism, the need for transfusion, and the blood and hemoglobin loss are reduced.
MyKnee cutting blocks allow for a reduction up to 60% of surgical step and related time for bone resections.
With the MyKnee system, up to 66% reduction of time and costs in washing, assembling and sterilization procedures can be obtained.
The MyKnee preoperative planning is based on the surgeon‘s specific preferences and submitted to the surgeon for approval through an interactive website.
For every case, the surgeon can modify all femur and tibia parameters such as femoral distal and anterior-posterior resection levels, femoral rotation, femoral flexion, femoral and tibial varus/valgus, tibial resection level and tibial slope.
The MyKnee team is always at surgeon‘s disposal and is pleased to collaborate.
Once approved by the surgeon, Medacta produces MyKnee cutting blocks using in house laser sintering technology. The guides are then shipped to be setup for surgery.
*The user interface may change without prior notice. The images shown above are for indicative purposes only showing the type of information provided by the interactive website.
The MyKnee process, carried out entirely in-house, begins with Medacta receiving CT or MRI images of the patient's leg and ends with the production of the patient-specific cutting blocks.
Starting from a CT or MRI scan of the patient leg, our MyKnee Engineering department carefully plans the surgery, according to the cutting and alignment parameters set by the surgeon.
On the MyKnee web-based platform, available 24/7, the surgeon is enabled to check, evaluate, modify, and validate his/her upcoming cases by means of a dedicated 3D planning tool.
Once the planning is validated by the surgeon, the MyKnee Engineers design the patient-matched guides and the production starts.
Medacta's patient-matched instrument platform covers solutions for every surgical scenario, including partial, total, and revision knee replacements, and allows for many surgical approaches such as bone referencing, ligament balancing, and muscle reduction. CT- or MRI-based cutting guides, MRI-based pin positioning blocks for uni- and total-knee implants, and CT-based guides to revise failed total-knee implants are available to offer a wide range of options to every surgeon. For GMK Sphere, a dedicated Kinematic Alignment planning protocol, MyKnee KA, is available to supplement the traditional mechanical alignment principles.
For each implant of the Medacta's comprehensive knee portfolio, a dedicated Myknee guide offers the opportunity to perform any knee arthroplasty with the enhanced accuracy and proven efficiency of the MyKnee system designed specifically for each individual patient.
The potential benefits of MyKnee technology can be further enhanced when used in conjunction with GMK Efficiency single use instruments.
GMK Efficiency is a complete single use instrument solution used to implant GMK Sphere or GMK Primary total knee systems.
It has been designed to optimize instrument management and logistics in the O.R. and throughout the hospital supply chain, providing benefits to every healthcare stakeholder. MyKnee and GMK Efficiency together offer an innovative and complete technological solution and deliver concrete benefits for the patient, surgeon and hospital.
To further emphasize the synergy between MyKnee and GMK Efficiency, the Efficiency KneePack was created to optimize the logistic benefits brought by the two systems into a single solution dedicated to total knee arthroplasty.
Efficiency KneePack is the Gold Standard in optimising resources and healthcare supply chain management. This complete solution includes all the components needed to perform a Total Knee Replacement. Delivered terminally sterile in a single, lightweight box, to streamline instrument management and reduce surgery time, it provides huge economical and logistical benefits to every healthcare stakeholder.
MyKnee is part of the MySolutions personalized ecosystem: an advanced network of digital solutions designed to improve patient outcomes and healthcare efficiency
MyHip is a system providing 3D preoperative planning and patient-specific guides, developed following the success of Medacta Patient Matched Technology
MyShoulder is a patient-specific instrumentation, allowing the surgeon to realize his pre-operative 3D planning, based on CT images of the patient’s shoulder. The pre-operative 3D planning allows to manufacture an humeral resection guide and a glenoid positioning guide.
This innovative concept combines different features giving potential benefits to both the surgeon and to the patient.
MySpine is a patient specific pedicle screw placement guide, allowing the surgeon to determine his pre-operative 3d planning, based on CT images of the patient’s spine. This innovative concept combines several different features to offer potential benefits to both the surgeon and the patient.
