BRACE CARE 

Liners and pads must be removed and cleaned regularly depending 

upon your activity level and perspiration. 

All liners and pads are held in place by hook fasteners and can easily 

be removed from the frames, hinges and straps. Wipe or HAND WASH 

with a MILD anti-bacterial soap, rinse well, then AIR DRY. Replace and 

position properly by pressing firmly against the fasteners. 

 

CLEANING HINGES 

The hinges on your brace are pre-lubricated. If sand, dirt or water gets 

inside the hinges, they may require cleaning and lubrication. Remove 

the condyle pad, open the hinge screws with the provided Allen 

wrench, and clean the hinge thoroughly and re-lubricate with any 

common synthetic lubricant (grease) from a hardware store. Check 

that the hinge is gliding smoothly and reassemble.  

  

PARTS, SERVICE, & WARRANTY 

Straps, liners and other comfort pads may need to be replaced due to 

normal wear and tear. If your brace requires replacement parts, you 

should contact the professional who assisted you in ordering and 

fitting the brace.  

 

Under normal use and conditions, the frames and hinges on your 

brace are covered by a one year warranty against defects in 

craftsmanship and breaking. Straps, liners and other comfort pads are 

backed by a six month warranty.

RANGE OF MOTION – HINGE ADJUSTMENT

This brace is shipped with a 0° hinge extension stop installed. Additional 

extension (EXT) and flexion (FLEX) stops are included with each brace, 

along with a tool to use to change the stops. (A typical ballpoint pen 

will also work.) When changing EXT or FLEX stops, be sure that the 

stops are fully inserted into the hinge and that both medial and lateral 

hinge stops are identical. Identical EXT and FLEX stops may be used 

simultaneously for knee immobilization.

EXT: 00, 100, 200, 300     |     FLEX: 00, 100, 200, 300, 450, 600, 900

ADJUSTING FLEX AND EXT STOPS

1.   INSTALLING STOPS

 

Each stop is labeled with an E (EXT) or F (FLEX) and the degree of  

 

control provided. Insert the desired stop into the appropriate side of  

 

the hinge with the degree numbers facing up. EXT stops go on the  

 

anterior side (front) and FLEX stops go on the posterior side (back)  

 

of the hinge. NOTE: When installing identical EXT and FLEX stops  

 

for immobilization, always install the FLEX stops on both hinges before  

 

installing the EXT stops.

2.  REMOVING STOPS

 

Insert the tool or a ballpoint pen into the opening of the hinge. While  

 

keeping moderate pressure, remove the stop with an outward prying  

 

motion. NOTE: When removing EXT and FLEX stops that were used for  

 

immobilization, always remove the EXT stops before removing the  

 

FLEX stops.

 

 

IMPORTANT: Do not bend the EXT or FLEX stops open as this can  

 

cause them to become unusable.

Liners and pads must be removed and cleaned regularly depending 

upon your activity level and perspiration. All liners and pads are held 

in place by hook fasteners and can easily be removed from the frames, 

hinges and straps. Wipe or HAND WASH with a MILD anti-bacterial 

soap, rinse well, then AIR DRY. Replace and position properly by 

pressing firmly against the fasteners.

Lubricating the hinges is not necessary. If the hinges become difficult to 

move or do not function properly, they may need to be repaired. This is 

a covered warranty within the specified time frame.

PARTS, SERVICE AND WARRANTY

Straps, liners and other comfort pads may need to be replaced due to 

normal wear and tear. If your brace requires replacement parts, you 

should contact the professional who assisted you in ordering and fitting 

the brace.

Under normal use and conditions, the frames and hinges on your brace 

are covered by a one year warranty against defects in craftsmanship 

and breaking. Straps, liners and other comfort pads are backed by a six 

month warranty.

NOTE: When installing identical EXT and FLEX stops for immobilization, 

always install the FLEX stops on both hinges before installing the EXT 

stops. When removing the stops, remove the EXT stops before  

removing the FLEX stops.
