Partial knee replacement simply means that only a part of the knee joint is replaced through a smaller incision than would normally be used for a total knee replacement.
Osteoarthritis, the most common type of arthritis is a degenerative joint disease in which the joint cartilage gradually wears away. As a result bones rub together resulting in extreme pain. The knee can be divided into three compartments:
ConforMIS® has developed the personalized knee resurfacing implants with unique advantages against traditional knee replacement options. To design a personalized implant for every individual, surgeon will perform the CT scan of the affected knee of the patient. A 3D image of a patient’s knee is created from CT scans and an implant is designed to conform exactly to individual size and shape.
The ConforMIS iTotal CR is an individualized patient specific implant for replacement of all the three compartments of the knee. It is thus most appropriate for patients with knee arthritis and knee damage requiring implant for not one or two but all the three compartments of the knee. It is designed specifically to match the natural shape of the articulating surfaces of the patient’s knee. This is done by mapping the articulating surfaces of the femur and tibia using the data from the CT scan of the patient’s knee. It also comes with disposable patient specific iJig instrumentation with built-in image guidance which simplifies the surgical procedure and improves the outcome.
The several advantages of this patient specific or iTotal customized total knee replacement implants over the regular traditional implants are:
Indications for use:
Note: The iTotal CR implant require the use of bone cement for fixation.
Although iTotal Customized total knee replacement systems are recommended in various conditions, they are not appropriate in patients with:
