Knapp II Knee Brace Key Benefits
-
Precision ROM Control: The patented Pop Stop™ hinge allows for range-of-motion adjustments in 10-degree increments. It can also be locked in full extension, making it an ideal choice for strict post-operative protocols.
-
Customizable Wrap Design: The anterior closure (front-fastening) design allows you to wrap the brace around the leg rather than pulling it on. This is essential for patients with significant swelling or limited mobility.
-
Advanced Moisture Management: Constructed with a unique blend of spacer mesh and double-knit fabric, featuring a Lycra back panel to prevent bunching and skin irritation behind the knee.
-
Targeted Stabilization: Available in two lengths to match your injury. The 12" version is optimized for medial/lateral (MCL/LCL) stability, while the 16" version offers the extended leverage needed for ACL/PCL protection and patella fractures.
-
Contoured Comfort: Malleable aluminum uprights can be hand-contoured to your specific leg shape, while the offset hinge center prevents irritation against the knee joint (condyle).
-
Professional Grade: PDAC Approved (L1832/L1833)
-
Available in Six Sizes from XS to XX-Large. See Size and Fit tab for sizing chart and measurement/fit help.
