  • The K4 Osteoarthritis Knee Brace is a custom adaptive OA Brace. It is ideal for active patients as it gives a desired and comfortable fit. It is an adequate and non-interfering remedy countermeasure for patients having mild to moderate OA.
    The difference between advanced orthosis from others is that it moves body weight directly to the calf from the thigh without putting much pressure on the knee joint helping stabilize the knee and stops the increase of deterioration.
  • Selecting The Exact Size: K4 OsteoAlign Knee Orthosis comes in 4 sizes, making it the closest equivalent to a custom fit knee orthosis on the market.
    The measurement instructions can be found in the photo . After measuring your thigh  circumferences, locate your ideal brace size (from Small to XL) on the size chart in photograph and select the size. We will customize your knee brace according to the size.
  • Unique Allen key-controlled telescoping condyle on a bilateral rigid frame which helps in straightening the knee joint to its natural position.
  • High strength aluminum alloy frame making the orthosis light yet load-bearing.
  • Glide hinges take the maximum load off the knee joint, providing supreme relief to the knee joint and cartilage.
  • Coating of silicon neoprene mold liners and foam strap paddings for the best grip and promoting suspension of the brace.
  • Neoprene condyles provide the highest comfort and lowest movement of braces.

After a minimum of eight braces I'm the first one that my son is able to move into while also being supported as he needs. The knee brace is rated as the best that he's worn.

It is the top knee brace, both in terms of quality and in terms of efficiency. It was pain-free all day in my left knee and I didn't experience any problems with slipping, even after seven hours of wear! Do not waste your money on cheap braces. In the long run, this brace is more affordable than the other brands.

It's a pretty precise device that is well-designed and requires adjustments properly, and it took some time to figure it out. Once I figured out how to adjust the device I discovered it was highly effective in helping me relieve my knee discomfort. There is a tendency to slide down if you don't get it tight, however even if it slips, it still provides relief from pain.
