The patient should be advised to inform the surgeon or attending physician about any changes
relating to the artificial joint.
Regular clinical follow-up examinations are recommended. If this is not possible, the surgeon or
attending physician should be provided with a control X-ray for assessment at least once a year.
AQ Implants GmbH provides appropriate instruments for revision procedures. Please refer to the
specific instructions in our user information and surgical techniques. Upon request, our product
specialists will provide support during revision surgery at your convenience.
Caution:
In case of any queries relating revision procedures, please contact the implant manufacturer.
Caution:
Exposure to strong magnetic or electromagnetic fields commonly used in magnetic resonance
imaging (MRI) can have adverse effects on the implant behaviour. For the latest safety informati-
on, please contact the implant manufacturer.

indicated for adolescents or children. It is important to note that the patient's bone conditions
can change significantly during growth which might compromise stable primary fixation of the
implant. Given this situation, supportive measures should be taken into consideration. In any
case, follow-up x-rays should be taken at regular tight intervals to identify any changes that might
pose a risk to the implant and take appropriate measures immediately.

Please ensure stable fixation of the adapter stem over the entire implant length in a closed ce-
ment mantle, particularly in small cemented stems, in order to ensure maximum fatigue strength
for natural loading.
Depending on the complexity of treatment (bridging of large defects), the biomechanical loading
of the adapter stems can increase significantly, e.g. due to the patient's high body weight or
increased activity level. In those circumstances, in particular in small stem sizes, appropriate
measures should be taken, e.g. partial weight-bearing.
Any non-observance of these recommendations can lead to fracture of the implant in extreme
cases, in particular in small stem sizes.

In case of any deviating combination due to patient-individual factors and thus clinically re-
quired indication, utmost care and diligence are recommended, including detailed patient infor-
mation and observance of all required safety precautions (e.g. partial weight-bearing).
Especially in small endoprostheses or small stem sizes of the REVISIO
