The company has started a voluntary recall of four of its knee replacement systems due to complaints of moisture on the patient-specific instrumentation for its iUni, iDuo, iTotal CR and iTotal PS systems. About 950 sets of custom instrumentation are affected by the recall.
Clinical research published online in July 2020 in The Journal of Bone and Joint Surgery Reviews found that the patients studied, who all received Conformis patient-specific iTotal PS (posterior-stabilized) knee replacement implants, were 90% satisfied, or very satisfied, 18–28 months post-surgery.
The femoral and tibial components of Conformis knee implants are composed of Cobalt Chrome Molybdenum Alloy (Co-Cr-Mo).
Our implants are covered under most private insurance, as well as Medicare, as any other joint replacement would be. As with any other procedure, we highly encourage you to connect with your surgeon's billing person to confirm coverage and take care of any necessary pre-authorizations.
Knee Stiffness One of the most common problems people experience after knee replacement is a stiff knee joint. Often these symptoms can cause difficulty with normal activities including going down stairs, sitting in a chair, or getting out of a car. Management of a stiff knee joint after replacement can be a challenge.
Usually, about three weeks after the surgery, you'll be able to walk without crutches for about 10 minutes. Your physical therapist will push you to add more to your regimen. Generally, it takes about a year for everything to settle, the knee to regain its strength, and all normal activities to become possible again.
Can I squat or kneel? Half squats for exercise are acceptable. Deep squatting is neither usually possible nor desirable after a knee replacement. Kneeling is not harmful but may not be comfortable.
In summary, TKA performed between the ages of 70 and 80 years has the best outcome. With respect to mortality, it would be better to perform TKA when the patients are younger. Therefore, the authors of these studies believe that from 70 to 80 years of age is the optimal range for undergoing TKA.
A TKR is now among the safest and most effective of all standard orthopedic surgeries. During a TKR, a surgeon removes the surface of your bones that have been damaged by osteoarthritis or other causes and replaces the knee with an artificial implant that is selected to fit your anatomy.
You shouldn't downhill ski or play contact sports such as football and soccer. In general, avoid sports that require jerking, twisting, pulling, or running. You should be able to do lower-impact activities, such as hiking, gardening, swimming, playing tennis, and golfing.
Pain management after a knee replacement is an absolutely necessary part of recovery. You can expect to take your medications for a few weeks. As with all narcotics, there are side effects, therefore one should follow the instructions exactly as they are written.
Traditional total knee replacement entails cutting into the quadriceps tendon, which connects the large quadriceps muscle group on the front of the thigh to the kneecap. The surgeon then moves the kneecap out of the way to access the arthritic joint.
New Materials Open the Way for 30-year Knees After testing under laboratory conditions, the Food and Drug Administration approved a manufacturer to label its implant as “good for 30 years of use.” While this resilience is a huge leap, even the company is careful in its claims.
How can you tell if a knee replacement is wearing out? Signs that your knee replacement is wearing out include pain, decreased joint function, swelling or stiffness in the area, and joint instability. If you have an artificial knee and experience any of those symptoms, talk to your doctor.
For 80–90% of people who have total knee replacement, the new joint should last about 20 years, and it may well last longer. If you've had a partial knee replacement, you're more likely to need a repeat operation – about 1 person in 10 needs further surgery after 10 years.

The Conformis experience is best described in our patients’ own words. Watch these knee replacement video testimonials from real Conformis patients to learn more about their surgery and recovery experiences.
The ConforMIS knee resurfacing system was introduced in approximately 2008. Up until this point, knee replacements including partial knee replacements or total knee replacements relied on pre-made implants that were implanted at the time of surgery. A surgeon often had to make a decision whether to place a component that was either a bit too large or a bit too small in a patient’s knee because a proper size was not available.
These replacements, however, are not patient specific implants but instead rely on patient specific cutting blocks which are applied to the knee at the beginning of a knee replacement procedure to make an initial bone cut.
