Why Do I Need an Open Patella / Open Back Knee Sleeve?

This neoprene knee sleeve is one of BraceAbility’s most popular knee braces with an opening around your patella (kneecap) and popliteal (behind your kneecap). BraceAbility’s open patella neoprene knee support was designed to protect your knee from future injuries, alleviate your knee pain, and provide comfortable support to your knees.

This knee sleeve can help treat many causes of knee pain and knee conditions including:

6 Reasons Why People Love This Neoprene Knee Sleeve

  1. It’s simple

This hassle-free slip-on recovery knee sleeve can be worn interchangeably on your right or left knee. There are no adjustable straps, closures, or fastens to deal with, making application quick and simple for athletes and non-athletes alike.

  1. The open patella and open popliteal design prevents bunching

If you find solid neoprene knee supports or ACE bandages sweaty and uncomfortable, this brace is definitely a better fit for you. Although full coverage knee sleeves provide a little extra support, they tend to bunch behind your knee joint and slide down during physical activities and sports. This open front/back neoprene knee sleeve is a more breathable option and stays put without bunching, giving your knees the support they really need.

  1. Great for athletes

The extra support provided by this knee brace allows athletes suffering from sports-related injuries to continue their normal fitness routine. However, powerlifters and bodybuilders often favor BraceAbility’s closed patella knee sleeve for its extra support.

  1. Made from 3/16” thick premium-grade neoprene

This discreet black knee sleeve is 13” long and 3/16” thick, making it not too flashy and flat enough to fit under ordinary pants, such as jeans, but still thick enough to provide adequate compression and support.

  1. Water resistant

This water-resistant knee brace is perfect for swimming, a great exercise for people trying to lose weight and much easier on your knees than running if you have knee problems.

  1. Reduces swelling and promotes healing

This neoprene material provides warmth and moderate elastic compression to your sore knee, which reduces swelling and encourages blood flow to speed up your healing process.

the open patella knee sleeve is great for all day comfort even while in the water

Is This Black Neoprene Knee Sleeve Waterproof?

Similar to the wetsuits scuba divers wear, this open patellar knee sleeve is unique because it is made out of premium-grade 3/16” thick neoprene, which is water-resistant. Meaning, this neoprene knee sleeve able to resist the penetration of water to some degree but not entirely.

If you do wear this knee sleeve when you are sweating profusely, showering, or for a swim, it is important to lay this knee sleeve flat to dry out completely before using it again for swimming, rowing, sailing, waterskiing, wakeboarding or surfing, for example.

I bought 2 braces. The bottom of the brace fits. The top is loose and Wriggles down within five minutes of wearing. It bunches up over my kneecap. The back is open but it pinches skin when it shifts. I would return them but the cost is too high. I would not recommend them.

Medial meniscus posterior horn tear with age related joint surface cartilage degradation.

The patella opening can not keep in place and is essential useless for my intended purpose, Compression slight restriction with lateral shifting and roterry movement. This for a medial meniscus posterior horn tear with significant hyaline cartilage degeneration that can causes swelling with weight bearing and movement. The compression is helpful. The patella opening catches on the sides of the actual patella particularly the lateral side down to the inferior pole. It slides down with prolonged use over a 8 hour day but not that bad given the limitations of the neoprene it is made of. It does get worm and causes perspiration that can irritate the skin and I would imagine cause a heat rash with prolonged use. All this said, should you share the same pathology, it is better with it than without and you may wish to use it for shorten periods of time to mitigate the heat effects if you can. So in all I recommend its use if only for the compression value it can provide for average or increase activities particularly standing and walking.
