ConforMIS Partial Knee Replacement

Partial Knee Replacement

The knee can be divided into three compartments: Patellofemoral, the compartment on the front of the knee which contains the knee cap, medial compartment, the compartment on the inside of the knee, and lateral compartment which is the area on the outside of the knee joint.

Traditionally, a patient with only one compartment of knee arthritis would undergo a Total Knee Replacement surgery. Partial Knee Replacement is a minimally invasive surgical option that preserves the knee parts not damaged by arthritis as well as the stabilizing anterior and posterior cruciate ligaments, ACL and PCL. This less invasive bone and ligament preserving surgery is especially useful for younger, more active patients as the implant placed more closely mimics actual knee mechanics than does a total knee surgery.

The smaller implants used with a partial knee replacement surgery are customized to the patient’s anatomy based upon CT scans of the patient’s knee. Partial knee replacement surgery will not alter the ability of the patient to eventually move to a Total Knee Replacement in the future should that become necessary.

iUni® G2 Bicompartmental Knee Resurfacing Device

The iUni G2 (the "i" stands for individualized) is a unicompartmental knee resurfacing device designed for patients with arthritic damage limited to either the medial or lateral compartment. Together with the iDuo G2 the iUni G2 provides patients with a range of partial knee resurfacing options in earlier stages of arthritis.

Many patients who receive a total knee replacement today actually have damage in just one compartment. Total knee replacements require your surgeon to remove healthy tissue from all three compartments. In addition, standard implants require your surgeon to choose from a variety of standard sized implants and to cut your bones to fit the implant.

ConforMIS has developed the only personalized unicompartmental knee implant designed to conform precisely to your own unique anatomy. Using iFit technology and information from a standard CT scan, ConforMIS creates a personalized implant designed to resurface just the affected compartment.

Personalized implants offer unique advantages versus traditional knee replacement options. Because each ConforMIS device is created specifically for you, the implants exactly mirror the surface contours of your knee, providing far more bone preservation. The implants also provide an anatomic fit with less bone cutting than traditional options.

Patients with unicompartmental disease are able to preserve their knee for future treatment options and may also experience faster recovery time and reduced post-operative pain than with traditional total knee replacement. In addition, our unique iJig instrumentation can improve alignment and provide a more natural feel to the knee, which can reduce implant wear and extend longevity.

iUni G2 Features:

• Manufactured for each patient, based on their individual anatomy
• Minimally invasive, minimally traumatic procedure
• Bone and cartilage preserving
• Appropriate for young and active patients
• Potential for less post-operative pain and shorter post-operative recovery
• Preserves the ability to move to other treatment options in the future

iDuo® G2 Bicompartmental Knee Resurfacing Device

The ConforMIS iDuo G2 (the "i" stands for individualized) is a bicompartmental knee resurfacing device designed for patients with arthritic damage to either the medial or lateral compartment plus the patellofemoral compartment located behind the knee cap. Together with the iUni G2, the iDuo provides patients with a range of partial knee resurfacing options in earlier stages of arthritis.

An estimated 30% of patients who receive a total knee replacement (TKR) today actually have damage involving one or two compartments of the knee. Total knee replacements require your surgeon to remove healthy tissue from all three compartments. In addition, traditional implants require your surgeon to choose from a variety of standard sized implants and to cut your bones to fit the implant.

Combining proven TKR principles for patella treatment with the unique advantages of a ConforMIS, partial knee system, ConforMIS has developed the only personalized bicompartmental knee implant designed to conform precisely to your own unique anatomy. Using iFit technology and information from a standard CT scan, ConforMIS creates a personalized implant designed to resurface just the affected compartment.

iDuo G2 Features:

• Manufactured for each patient, based on their individual anatomy
• Minimally invasive, minimally traumatic procedure
• Bone , cartilage and ligament preserving vs. TKR
• Appropriate for young and active patients
• Potential for less post-operative pain and shorter postoperative recovery
• Preserves the ability to move to other treatment options in the future

The iDuo G2 Process:

Should you and your surgeon determine you are a good candidate for the iDuo G2, your surgeon will give you an order for a ConforMIS knee scan at a local CT imaging center. Your CT scan will be sent to ConforMIS for review and implant production. Your iDuo G2 should be available in approximately six weeks from receipt of the scan.

The personalized implant will be shipped to your surgeon along with personalized surgical instruments derived from your CT scan called iJigs. The iJigs will guide the surgeon in determining the precise placement of your implant.

Following surgery, your care will focus on reducing and controlling swelling, pain management and physical therapy. You may wear a brace for a few weeks.
