Partial knee replacement
General indications: Partial knee replacement is intended for use in individuals with joint disease resulting from degenerative and post-traumatic arthritis, and for moderate deformity of the knee.
Contraindications: Partial 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, or excessive body weight.
Common side effects of knee replacement surgery: As with any surgery, knee replacement surgery has serious risks which include, but are not limited to, 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 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 of the implant include dislocation, loosening, fracture, nerve damage, wear of the implant, metal sensitivity, osteolysis (localized progressive bone loss), and reaction to particle debris. Partial 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 help 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. Ask your doctor if robotic-arm assisted surgery is right for you.
