Iforma Knee Interpositional Device

iForma™ Knee Interpositional Device

The ConforMIS iForma is aminimally invasive treatment option for patients with mild-to-moderate osteoarthritis in either the inner (medial) or outer (lateral) compartment of the knee.

EachiForma is designed froma patient's ownMRI scan. The diagnostic scan provides information about the shape and condition ofthe knee. If you and your surgeon determine that you are a good candidate for the iForma, that data is then used to designa personalized implant.

The iForma slips into theknee between the thigh bone and the shin bone. Because of the personalized design, the iForma closely conforms to the natural shape of yourjoint, using the anatomicfeatures to retain its proper position. No bone cuts or cartilage removal is required.

Once inserted, the iForma restores the geometry of yourjoint and realigns the knee. It also provides a smooth articulating surface for the end of your thigh bone, preventing painful bone-on-bone rubbing. Patients should be able to return to light to moderate activity after recovery and may delay the progression of disease due to improper loading of one compartment.

By preserving the joint, the iForma maintains the ability to safely move to more invasive knee replacement options at a later date, if one becomes necessary. This may be particularly important for patients considered too young for traditional knee replacement.

iForma Features:

Treats mild-to-moderate osteoarthritic degeneration
Manufactured for each patient based on information from their MRI scan
Minimally invasive, minimally traumatic procedure
2-3 inch average incision length, typically a 40-60 minute procedure
No bone cuts or articular cartilage removal required
Preserves the ability to move to other treatment options in the future
May result in less post-operative pain and faster recovery

The iForma Process:

If you and your surgeon believe that you may be a good candidate for an iForma, your surgeon will give you a prescription for a ConforMIS knee MRI scan. After reviewing the scan to ensure that you are indeed a good candidate,your surgeon will send in an order toproducethe implant.Your iForma should be available in approximately four weeks from receipt of the order.

Following surgery, your care will focus on swelling and pain management. You may wear a brace for a few weeks. Your surgeon will also prescribe exercises and activities to strengthen your knee muscles. Patients are generally able to walk and weight-bear within2 weeks following surgery, but each patient is unique and only you and your surgeon can determine your tolerance and level of ability. For optimal recovery, activities that stress the knee should be resumed slowly and as tolerated, allowing your knee adequate time to adapt to the implant.

iUni™Unicompartmental Knee Resurfacing Device

The iUni (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, the iUni 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 (clickhere toreview knee anatomy).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 technologyand 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 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

The iUni Process:

Should you and your surgeon determine you are a good candidate, 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 iUni 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.Your surgeon and physical therapist will also prescribe exercises and activities to strengthen your knee muscles.

Patients are generally able to walk and weight-bear within 2 weeks following surgery. For optimal recovery, activities that stress the knee and weight-bearing should be resumed slowly and only as tolerated, allowing your knee adequate time to adapt to the implant.

While every patient's experience is different, you should expect to feel significant pain and function improvement within 2 to 3 months of your procedure and should be able to return to most activities within3 to 6 months.

iDuo™Bicompartmental Knee Resurfacing Device

The ConforMIS iDuo (the "i" stands for individualized) is a bi-compartmental 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, the iDuo 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 involving either the inner or outer compartment plus the area behind the knee cap. Total knee replacements require your surgeon to remove healthy tissue from all three compartments (click hereto review knee anatomy).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.

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

Patients with bicompartmental 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.

Preserves the ability to move to other treatment options in the future

The iDuo Process:

Should you and your surgeon determine you are a good candidate for the iDuo, 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 should be available in approximately six to eight weeks from receipt of the scan.

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. Your surgeon and physical therapist will also prescribe exercises and activities to strengthen your knee muscles.
