DonJoy is please to introduce the most cost effective functional ligament knee brace known as the SE-4 Point, with its patented 4-point dynamic leverage system technology. The SE 4-Point Legend has made a name for itself as a strong and low profile brace in the off-the-shelf market.
The SE 4-Point provides the basic frame of the traditional legend at a fraction of the cost. It is ideal for moderate to severe ACL, and/or PCL, MCL and LCL instabilities. The SE-4-Point is recommended for use in all contact sports. The brace features a non-chip outer covering which is also safe for salt and fresh water activities.
