Continuing challenges in Total Hip Replacement (THR) include:
Medacta designed the MyHip to address these issues, focusing on patient well-being and improving accuracy in implant positioning and sizing, through:
MyHip is a system providing 3D preoperative planning and patient-specific guides,
developed following the success of Medacta Patient Matched Technology
Accurate implant positioning and sizing
Complete 3D preoperative planning with 3D kinematic simulation, which considers pelvic tilt
Complete in-house technology the MyHip process is entirely performed by Medacta
A personal MyHip technician just for you
Only 3 weeks lead time the shortest delivery time in today’s market for this technology
Medacta receives the CT images of the patient‘s leg.
A virtual position of the implant is proposed to the surgeon who can modify the planning as he wishes.
Starting from the 3D reconstruction of the joint and following the surgeon preferences the MyHip preoperative planning is performed.
Once the planning has been validated by the surgeon, the in-house manufacturing process starts.

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.
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.
