6 Compensating for mediolateral movement (fig. 4+5)
If mediolateral side play develops, it may be reduced by tightening the Axis Nut (9). Remove the
Safety Plate (10) and tighten the Axis Nut (9). Overtightening the nut may restrict normal movement
of the Knee Joint. Be sure to install the Safety Plate (10) after the adjustment has been made.
7 Foam cosmetic cover
The 3R24 or 3S124 Foam Cover is used with the 3R17/3R33 Knee Joints.
Attention!
To eliminate noise in the cosmetic foam cover, use 519L5 Silicone Spray. Do not use
talcum powder! Talcum powder reduces the lubrication of the mechanical parts, which
may lead to a malfunction and thus increase the risk of failure. Using this medical
product after application of talcum powder will render all claims against Otto Bock
HealthCare null and void.
Useful information
To optimize sliding and for eliminating noises, please apply 519L5 Silicone Spray directly
on the friction surfaces of the foam cosmetic covers.
Attention! Please inform your patients.
Due to different environmental conditions and conditions of application, the function of
the knee joint can be impaired. To avoid the risk of accident and possible injury to the
patient, the knee joint must no longer be used after a noticeable loss of function has oc-
curred. This noticeable loss of function can be for example stiffness, non-attainment of the
extension stop, decreasing swing phase or stance phase stability, abnormal noises, etc.
Measure
Have the knee joint examined by a specialist workshop where service parts or, if neces-
sary, the entire knee joint will be exchanged.
