What Does The Surgeon Do In The Or During Knee Replacement Surgery
Surgeons are equipped with many tools during a Conformis knee replacement to ensure the best chance for a successful procedure. Before each case, the surgeon receives a pre-operative plan called an iView that is designed specifically for each case. This allows him or her to better understand that patients anatomy before starting the procedure.
Once the surgeon has reviewed the iView, they use a series of disposable 3D printed cutting blocks designed for that patients anatomy to create the bone resections outlined in the preoperative plan. The surgeon then cements the custom-made femoral and tibial implants.

Artificial Knees Made To Order
A startup company is taking a customized approach to knee replacement surgery, creating knee implants on demand that exactly match a patients anatomy. The company, ConforMIS, based in Burlington, MA, is bringing the technology of rapid prototyping, which converts a three-dimensional computer design into a physical object, into the field of orthopedics. The company believes that such custom-made implants can make knee replacement surgery faster, more accurate, and less traumatic to the patient.
Knee replacement surgery repairs damage and relieves pain in patients with severe osteoarthritis or knee injury. Total knee replacement involves removing diseased cartilage and bone from the surfaces of the knee jointthe thigh bone, shin bone, and kneecapand replacing them with an artificial joint made from a combination of metal and plastic. A partial knee replacement can also be performed on one part of the joint.
Typically, a surgeon chooses an artificial joint from several options of different sizes. ConforMIS, however, creates a custom implant based on imaging data of a patients knee joint, a technology that the company calls iFit. ConforMIS transforms images from CT or MRI scans into a three-dimensional computer model using computer-aided design software, which serves as a template for manufacturing the implant.

What Is Conformis Knee Replacement
Looking for information on ConforMIS Knee Replacement? Sometimes people endure injuries or disease that require that they undergo knee replacement surgery. If you or someone you know is in this position and are considering your options, you should be aware the ConforMIS Knee Replacement is an excellent choice.
ConforMIS is a leader in custom knee replacement that uses only the highest-grade quality materials when manufacturing their knee replacements. Surgery time is minimal, and recovery is complete with the eventual full use of the affected knee as the most likely outcome.
Whats The Difference Between Conformis And Traditional Total Knee Replacement
Traditional total knee replacement surgery uses off the shelf implants that come in fixed sizes. While this method has brought lasting relief to many people, it doesnt always work out that way. Sometimes an implant can be too big or too small and a surgeon has to use the closest fit. In addition to this, traditional replacement surgery relies on alignment by hand, which makes exact precision impossible and can sometimes leave a patient with lasting discomfort.
Conformis technology uses data from a patients CT scan to create an accurate 3D model of their knee, replicating their unique structure and curves, and even correcting for deformities. This software then creates the implants, precisely matching the patients knee. During surgery, the surgeon uses this sophisticated, less invasive technology to perform the surgery. The patient is left with a perfectly fitted knee replacement.

The 3d Printing Process For Knee Replacement
Receiving a customized prosthetic knee joint involves more steps than receiving a traditional knee implant, including:
- Obtaining high-resolution imaging of the knee joint
- Creating a computer model of the natural joint
- 3D printing of the custom joint by the manufacturer
- Implanting the joint using computer modeling to determine angle of placement and other surgical approaches
3D printing of knee joints usually employs a technique called additive manufacturing. The printing material is applied in layers, one on top of the other, until a precise model of the natural joint has been created. 3D artificial knees can be made of metals, plastics, or a combination of the two, just like traditional prosthetic joints.
Sometimes, orthopedic surgeons also order customized 3D printed tools to aid in placing the artificial joint during surgery. They may use computer programs that guide them in placing the prosthesis at the precise angles required to mimic the natural knees function.
Your Best Knee Replacement Solution Should Be Individualized
Custom-made no longer applies to only furniture, vehicles, or accessories. Designed and crafted specifically for your body and lifestyle, the new standard for your knees is the highly successful Conformis knee implant.
From cyclists, marathon runners, salsa dancers, golfers, and other top athletes, getting back to an active lifestyle with Conformis implants is a breeze.
How does Conformis work? Advanced 3D imaging technology is combined with the latest manufacturing methods so each and every implant is unique. Theres no one size fits all here.

Conformis Total Knee Replacement
There are many different types of knee replacements that are available with total knee replacement surgeries, but there are not as many as unique as the ConforMis knee.
What is it? The ConforMis is a type of knee replacement that is crafted specifically to your knee. A CT scan is done of the knee before surgery, and the replacement is crafted out of cobalt chromium molybdenum, a standard metal used in orthopedic implants, based on the imaging to make it more specific to you.
How is it any better from other knee replacements? With the ConforMis knee, it is specifically crafted to fit your knee. With other knee replacements, they are made in bulk as a generic knee. They dont always fit correctly on the knee, whereas the ConforMis knee is crafted to fit the knee similar to the original knee.
The plus side of the ConforMis knee:
- Less bone is removed during surgery
- Less bleeding occurs after surgery
- Less pain after surgery
- Recovery time is faster
- Range of motion is better
- Kinematics of the knee closely resemble a normal knee more than other generic knees on the market
- High satisfaction rate with patients that have the ConforMis knee
- Resurfaces the original knee, as opposed to replacing it

Cfms Stock: Why Under
The global knee joint reconstruction market is projected at more than $9 billion
Shares of medtech Conformis surged more than 17% in pre-market trading on Tuesday after the company said it had received clearance in Australia for its total knee replacement system. CFMS stock has touched a 52-week high price of $1.48 per share twice since January.
The patient-specific iTotal PS total knee replacement system, which was launched in the U.S. in 2016, got a green light for use down under by the Therapeutic Goods Administration, part of the Australian Department of Health. The Therapeutic Goods Administration authorizes the marketing of medical devices and other healthcare products in Australia, according to a Conformis press release. This implant is specifically designed to restore the natural shape of each patients knee, and to avoid rotation and sizing compromises associated with post-surgery pain.
With this clearance, we have greatly expanded the number of potential patients who will be candidates for our personalized knee replacement implants, and we are thrilled to offer the benefits of our unique technology to surgeons in Australia who prefer a posterior-stabilized design to a cruciate-retaining one, said Mark Augusti, president and CEO.

Are Newer Knee Implants Much Different From Old Ones
Yes. There are newer high-flex knee designs that allow greater safety during deep knee bending. There are also newer gender-specific total knees made to fit the anatomical differences in the knees of men and women. All knee replacement components that we used incorporate these modern design features.
Other variations in total knee implants include a ceramic oxinium surface, the rotating-platform knee, and other brands marketed by implant companies. Discuss this with your surgeon and medical team they will help you make an informed choice.
So Just How Good Can A Custom
Ive been doing Conformis custom-made knee replacements since 2012 now, and was the first surgeon in the UK to implant a Conformis prosthesis. Our practice is now a Surgical Visitation Centre for Conformis, and we have a steady flow of surgeons from across the UK coming to join me in theatre to learn the specific techniques for implanting Conformis prostheses.
But just how good are they, really?
The proof is always in the pudding and for us, the pudding means proper clinical audit, national registries and prospective research projects . theres now increasingly convincing evidence that Conformis knees are indeed the very best knees available, with:
- 95% patient satisfaction rates, compared to just 80 to 85% with a standard off-the-shelf knee in unhappy patients, which is massive!
- 3A rating from ODEP:
- The latest reports from the Beyond Compliance register showing a 60% reduction in early revision rates with the Conformis knee compared to the average knee on their register:
The question is, what does this actually equate to and look like in real life?.

Perfect Knee Implants Courtesy Of A 3
After D.C. resident Christina Starr was hit by a motorcycle in 2009, three surgeons told her not to return to ballet class. After five years of cortisone shots, she started looking into getting a knee replacement, and Bethesda surgeon Chris Cannova offered something she hadnt heard before a customized knee replacement made using a 3-D printer.
Two days after the surgery this August, she walked out of the hospital without crutches, and six weeks later, she returned to dance class.
They told me, Weve never heard of anybody getting a knee replacement and then going back to any kind of dance activity where you have you have to tilt and spin and pirouette. she said.
Cannova and his partner are among the first surgeons in the Washington area using knee implants made with a 3-D printer, and they have used them in hundreds of operations in the past two years. The knee implants, produced by Massachusetts-based Conformis, are put into use by just a few dozen doctors in the Mid-Atlantic area. Since the company first made the technology commercially available in June 2011, the process has been used in more than 10,000 procedures.
The 3-D printers are machines that produce physical objects by spraying ultra-thin layers of material on top of one another. In recent years, the medical industry has been using printers to create a variety of products from artificial heart valves to skin grafts. Some are even experimenting with printing entire organs.
One Patient One Implant
More natural feel
ConforMIS custom-made knee implants are designed to mimic every aspect of your natural knee from its shape, to the way it bends and extends. We restore the natural shape of your unique anatomy, corrected for deformity, rather than replacing it with a pre-determined, standardized geometry.
Optimal bone preservation
Our innovative design allows for an implant that is thinner than traditional knee implants. A thinner implant can preserve more of your natural bone, which may be beneficial for future treatment options.1
Traditional, off-the-shelf knee replacements are manufactured in 610 standard sizes. During surgery, the surgeon selects the closest approximate size and makes necessary adjustments to fit the implant to your knee. The result is a replacement knee that is nothing like your own knee. This often can lead to pain or discomfort after surgery.
Multiple studies have shown satisfaction rates with iTotal CR well above the average of 80% seen in off-the-shelf knee patients.2,3

What About A Custom Knee Replacement Made Just For My Leg
One of the most exciting innovations when I was practicing is the concept of custom-manufacture of knee implants that are made specifically to each patients size and unique anatomy. CT or MRI imaging is used to determine the precise anatomy of the patients ankle, hip, and knee. These data are sent to a company called CONFORMIS , where the metal and plastic pieces are custom-made for the patient in about 5-6 weeks, much like a tailor-made suit. The instruments used to implant the knee prosthesis are designed for a one-time use, specific to the patient, and are made of a biodegradable material. One neat package contains everything needed for the operation, and is unique for each knee joint, fitting only that one.
We used this in my practice beginning in 2013 and found it truly innovative, a meaningful step forward in knee replacement surgery. Our results showed earlier and easier recovery for the patient, and x-rays that are beautifully precise in terms of rotation, alignment, and sizing. This technology incorporates all of our knowledge and design understanding in knee replacement, worldwide. It increases patient safety, promotes quality and consistency, ensures precision and a perfect fit every time, and therefore has our full support.
Conformis Ifit Customized Knee Replacement
Orthopaedic Associates and Dr. Theodore Macey are proud to offer the latest in customized knee replacement technologyiTotal® from Conformis. Conformis customized knee replacements are designed to match the unique size and shape of each patients knee.
In traditional knee replacement surgery, the surgeon selects an off-the-shelf implant from a range of standard fixed sizes, and then has to make the necessary adjustments to fit the implant to the patient during the procedure. Because these off-the-shelf knee replacements arent designed to your specific anatomy, surgeons have to compromise on implant fit. This compromise may result in having implant overhang or underhang . It could also result in an implant that isnt aligned properly.
Clinical studies have demonstrated that these compromises on fit can cause residual pain after surgery. Conformis designs partial and total knee implants to fit the patient, not the other way around. Proven elements of standard knee replacement are combined with proprietary iFit Image-to-Implant® technology to create customized knee implants and surgical instrumentation that are designed to fit your knees natural shape and curves.

Find The Best Knee Replacement Implant: Top Brands
There are more than a dozen manufacturers of artificial knee implants. However, like anything else, some knee implant manufacturers have a larger market share than others. In the US, the most popular knee replacement parts manufacturers are Zimmer , Stryker, DePuy and Smith & Nephew.
Here are the top brands and styles used by surgeons in the US.
Zimmer is the most popular manufacturer of knee replacements. In fact, according to Zimmer, more than 25% of knee replacements implanted worldwide are a Zimmer product. Thats a whole lotta implants!
Biomet, who has recently merged with Zimmer and is now called Zimmer Biomet, offers a nickel-free implant for those with allergies. They also offer an antioxidant polyethylene material insert component to pair with their tibial and femoral parts. In saything this, there is nothing to prove that antioxidant plastic holds any true benefit. Admittedly, it sounds pretty good though!
Among the most popular manufacturers in the US, Stryker offers total, partial, and revision knee replacement systems that are suitable to a wide variety of patients. Stryker implants are used in over 100 countries.
Smith & Nephew offers a wide range of replacement variations that fall under their Legion family. This includes replacements made from oxidized zirconium, a nickel-free metal thats suitable for patients with metal allergies.
