Your orthopedic surgeon will choose which knee is best for you. Below are some of the more common Zimmer® products you may hear mentioned.
The Zimmer Uni High Flex Knee is an advanced partial knee replacement that's designed for those who need joint replacement but only have damage on one side—or compartment—of their knee and are no longer as active as they once were because of pain.
Unlike some unicompartmental knee implants, the Zimmer Uni High Flex Knee accommodates deep knee bending, which is referred to as high flexion. High flexion is particularly important if you enjoy activities such as golf, gardening, or playing with small children, during which kneeling is common. The Zimmer Uni High Flex Knee does not guarantee deep knee bending; however, it is designed to safely accommodate up to 155º of flexion in patients who are able to achieve it.
In addition, the Uni High Flex Knee was designed for placement using today's minimally invasive techniques, which, if you are a candidate, preserves more of your natural anatomy and is helping many people get back to life and work faster than patients who undergo traditional knee replacement surgery.
In clinical studies, Zimmer Unicompartmental knee replacements have a 98% cumulative success rate at 10 years, which is one of the highest success rates seen in unicompartmental knees to date.
Zimmer Gender Solutions High-Flex Knees are specially made to fit the unique anatomical shape of a woman's knee. They feature:
The NexGen LPS-Flex Mobile and LPS-Mobile Bearing Knee Systems are total knee replacements that are designed to both bend and rotate. Each system includes a metal femoral component that replaces the end of the thigh bone (femur), a metal tibial base plate that replaces the top of the shin bone (tibia), and a plastic articular surface component that is loosely attached to the tibial base plate and serves as artificial cartilage between the femoral component and the tibial base plate. The femoral component and tibial base plate are implanted using bone cement. As in most total knee implant systems, the femoral component of a mobile-bearing knee rides on top of the articular surface component to provide the knee's bending movement. A mobile-bearing knee design allows the articular surface component to rotate on the tibial base plate to allow free movement as needed.
The Zimmer Gender Solutions Patello-Femoral Joint System is an early intervention option for active patients that preserves more bone while allowing for a smaller incision. This means you have the potential for a quicker recovery. The procedure is designed to be used with a Zimmer Minimally Invasive Solutions™ technique, which minimizes damage to soft tissue. During the procedure, Zimmer advanced surgical instruments assist your surgeon in achieving accurate implant placement.
The Zimmer Gender Solutions Patello-Femoral joint is designed to accommodate the differences between male and female knee anatomy, providing more natural knee movement as the knee bends. This treatment is not appropriate for everyone; only your orthopedic surgeon can tell if you are a candidate for patello-femoral knee replacement.
DeNovo NT Graft consists of natural human cartilage and is used in the repair of joint cartilage damage. It is an allograft, which means that it is obtained from another person. Unlike organ transplants, however, there is a very low risk of the DeNovo NT Graft being rejected by the body. Allografts have been used successfully for many years in a wide variety of medical procedures, including joint repair and dental restoration.
The graft offers single-stage surgery where small pieces of juvenile joint cartilage are implanted into the affected area with a simple surgical technique using a natural sticky glue called fibrin. The graft contains living cartilage cells that have the potential to grow and repair the defect area. In a recent study, patients with knee defects treated with DeNovo NT Graft reported less pain and an improved ability to function.
