11. Advice on Optimal Orthosis Functionality

Problem
The system joints do not unlock.
The system joints do not lock
correctly.
The system joints do not lock
correctly in step lock function.
Cause
The locking and unlocking parts
are still loaded.
The patient does not apply a mini-
mal extension moment.
The orthosis is not torsion-resist-
ant (bilateral construction). Only
one system joint locks.
One system joint is/both system
joints are still in permanent unlock
function.
The step lock pawls lock in differ-
ent flexion positions.
Extension stops with different
extension degrees (e.g. medial
10° and lateral 20°) have been
mounted.
The orthosis is not properly
produced (e.g. not torsion-resist-
ant, no parallel alignment of the
system joints).
Measure
The patient has to take the body
weight off of the orthosis (e.g. by
sitting down on a chair).
The patient has to take the body
weight off of the orthosis (e.g. by
sitting down on a chair) and has
to apply an extension moment
themself or with the assistance of
another person (e.g. by pushing
the knee back with the hand).
The system joints must be locked
with passive force. The patient
or another person must push the
knee backwards.
The locking pawl must be pressed
against the joint's upper part until
the locating pin is pushed out of
its bore in the joint's upper part.
The patient must fully extend their
knee until the system joint locks.
Retry unlocking and locking the
system joint.
Please note that a 5° extension
stop and a 5° step lock stop disc
are mounted for the premounted
step lock function. Use a 0° step
lock stop disc for other extension
stops.
Only mount extension stops with
the same degree of extension.
Correct the alignment of the
orthosis.
