The Ottobock MOBIS is not intended to be used as a guide to obtaining reimbursement
for prosthetic components in the USA.
Due to the small space requirements above the axis it is suitable for long above knee amputation
levels. Further, the 3R17 and 3R33 Knee Joints can be interchanged with our 3R20, 3R36, 3R22
and 3R34 Knee Joints.
Attention!
Please avoid exposing prosthetic components to surroundings that corrode metal parts,
for example, freshwater, saltwater, acids and other liquids. Using this medical product
in such environmental conditions will render all claims against Otto Bock HealthCare
null and void.
Please inform your patients.
