Triathlon Knee Replacement
We understand that making sure you know what to expect from the knee replacement experience is important to you. If you have additional questions as you are reading through this material, please reach out to us to discuss.
If you haven’t experienced adequate relief with medication and other conservative treatments, knee replacement may provide you with relief from your arthritis.
Diagnosis and treatment of knee pain
Each patient is unique and can experience knee pain for different reasons. It’s important to talk to us about the reason for your knee pain so you can understand the treatment options available to you.
Arthritis, one possible reason for knee pain, can affect one or more of the three compartments of the knee. There are different areas where arthritis can affect the knee joint:
the inside of the knee, or medial compartment
the outside of the knee, or lateral compartment
the top of the knee is also known as the kneecap, or patella compartment
Pain from arthritis and joint degeneration can be constant or come and go, occur with movement or after a period of rest, or be located in one spot or many parts of the body. If you haven’t experienced adequate relief with medication and other conservative treatments, total knee replacement may provide you with relief from your arthritis.
Total knee replacement
Total knee replacement is a surgical procedure in which the diseased or damaged area of all three compartments of the knee is replaced with an artificial joint called an implant.
Triathlon Knee Replacement
The Triathlon Knee is different from traditional knee replacements because of the single radius design. This means that as your knee flexes and extends, there is a constant center of rotation, like a circle. Traditional implant designs follow an oval motion. Triathlon is designed to replace the knee’s natural circular motion and offer enhanced stability as you bend and flex your knee.1-2
IMPORTANT INFORMATION
Knee Replacements
Total knee replacement is intended for use in individuals with joint disease resulting from degenerative, rheumatoid and post-traumatic arthritis, and for moderate deformity of the knee.
Knee replacement surgery is not appropriate for patients with certain types of infections, any mental or neuromuscular disorder which would create an unacceptable risk of prosthesis instability, prosthesis fixation failure or complications in postoperative care, compromised bone stock, skeletal immaturity, severe instability of the knee, excessive body weight, or known or suspected sensitivity and/or allergy to any material in the device.
As with any surgery, knee replacement surgery has serious risks which include, but are not limited to, pain, infection, bone fracture, peripheral neuropathies (nerve damage), circulatory compromise (including deep vein thrombosis (blood clots in the legs)), genitourinary disorders (including kidney failure), gastrointestinal disorders (including paralytic ileus (loss of intestinal digestive movement)), vascular disorders (including thrombus (blood clots), blood loss, or changes in blood pressure or heart rhythm), bronchopulmonary disorders (including emboli, stroke or pneumonia), heart attack, and death.
Implant related risks which may lead to a revision include dislocation, loosening, fracture, nerve damage, heterotopic bone formation (abnormal bone growth in tissue), wear of the implant, metal and/ or foreign body sensitivity, soft tissue imbalance, osteolysis (localized progressive bone loss), and reaction to particle debris. Knee implants may not provide the same feel or performance characteristics experienced with a normal healthy joint.
The information presented is for educational purposes only. Speak to your doctor to decide if joint replacement surgery is right for you. Individual results vary and not all patients will receive the same postoperative activity level. The lifetime of a joint replacement is not infinite and varies with each individual. Your doctor will counsel you about how to best maintain your activities in order to potentially prolong the lifetime of the device. Such strategies include not engaging in high-impact activities, such as running, as well as maintaining a healthy weight. It is important to closely follow your doctor’s instructions regarding post-surgery activity, treatment and follow-up care. Ask your doctor if joint replacement is right for you.
