Patient-specic C R U C I A T E - R E T A I N I N G knee replacement system

is the only individualized total knee system on the market today.

iTotal G2 is designed to achieve unique advantages not possible with off-the-shelf knee implants. Our proprietary iFit® technology, coupled with the belief that implants and instruments should be unique to the patient, help us create an “individualized solution” in four key areas: 3. SIMPLIFIED SURGICAL TECHNIQUE

IMAGE IMPLANT People vary in more ways than gender, race, and size. At ConforMIS, we believe that optimal implant t and performance requires an individualized approach. Our iFit® Image-to-Implant™ technology transforms traditional imaging data into patient-specic implants and instruments.

Patient-specic condylar offset and intercondylar width Patient-specic anatomic J-curves Medial and lateral poly inserts matched to femoral offset Patient-specic rotation and coverage

No more compromises on femoral t. Femoral overhang of 3mm has been shown to be a signicant cause of residual pain in total knee replacement, affecting 40% of men and 68% of women in one study.1 iTotal G2 is designed to address the wide variations in patient anatomy that lead to overhang and undercoverage with off-the-shelf total knee systems. Patient-specic femoral for proper t without sizing compromises

No more compromises on tibial coverage and rotation. Tibial rotational 2 errors were found in 44% of painful knees using off-the-shelf designs. iTotal G2 is specically designed to address known sources of pain due to rotational errors common with traditional total knee systems. Patient-specic tibial tray set to proper rotation Anatomic tibial axis alignment The result is a knee replacement so precise that it virtually eliminates sizing compromises common to off-the-shelf knee replacements.

SHAPE Shape drives kinematics. Studies show total knee replacements, including single radius designs, alter patient kinematics.3 Many patients report that their knee does not feel “natural.”4 iTotal G2 starts with each patient’s medial, lateral and patellofemoral J-curves, corrected for deformity, as the basis for implant design. Separate dual-balancing™medial and lateral poly inserts: • Matched to femoral offset • Respect patient’s medial and lateral joint lines • Allows for intraoperative exibility iShape™ technology: • Respects patient’s condylar geometry • Retains naturally occurring...

Creating an implant to t the patient, rather than shaping the patient to t the implant, opens new possibilities in design. • 6-cut design for a thinner implant without sacricing strength5 • Help avoid soft tissue impingement (e.g., popliteus tendon “popping”), which traditionally would require releases to correct • 28% volumetric bone preservation advantage for iTotal G2 compared to standard off-the-shelf implants6 Contact area (mm2) at 0°, 60° and 90° of exion Due to its broad coronal radius and coverage, iTotal G2 offers contact area throughout the range of motion.

SIMPLIFIED SURGICAL TECHNIQUE Patient data enables a reproducible surgical technique using pre-navigated iJigs.® Disposable, patient-specic iJig instruments for every step: • iView surgical planning images provide detailed resection values that can be used to verify accuracy throughout the surgery

iTotal G2 includes implants and instruments in a single box. Single instrument tray When it comes to efciency in the operating room, less is more. iTotal G2 is delivered in a single, pre-sterilized kit a few days before surgery. • No implant inventory • Pre-sterilized, disposable instruments • A single reusable instrument tray • Easy set up and tear down
