Relief for osteoarthritis of the knee

In cases of osteoarthritis, it is important to manage pain while also mobilizing the knee. Here, the GenuTrain A3 has proven to be a valuable aid. With a star-shaped functional cushion, it provides targeted stimulation to the stabilizing muscles around the knee and kneecap. Specially nubbed zones relieve pain in the typical pain area, the inner side of the knee.

Fit again fast

Debilitated patients will particularly appreciate the expansion zone in the calf area, as it makes the GenuTrain A3 even easier to put on. With each movement, the special osteoarthritis support exerts a medically effective intermittent compression massage.

In addition to relieving pain, it also activates the leg muscles and improves their coordination. This protects the knee even during movement. There is no reason not to start physiotherapy and cautious training. After all, even in cases of osteoarthritis of the knee joint, being active is key to good health!

Wash my brace?

Washing regularly helps our supports maintain their shape and last longer. All Bauerfeind supports are made with machine washable materials.

Here's how to care for your brace:

For products with Velcro straps, pads or inserts, remove them if possible, or fasten them securely at the place provided on the brace. Machine wash your brace in cold water using the gentle or delicate cycle. Wash separately using a laundry detergent with no additives (do not use fabric softener or Woolite). Lay your support flat and let it air-dry; do not put it in the dryer. Proper washing and drying helps your knit support maintain its elasticity and original fit.

What’s the difference between GenuTrain, GenuTrain A3, GenuTrain P3 and GenuTrain S?

Each brace is designed specifically for a different type of injury or pain. You can find comprehensive information on the Product Details page. Here’s an overview:

  • GenuTrain® is designed for weak, swollen or painful knees. This brace support is best for nagging pain such as tendinitis/jumper’s knee.
  • GenuTrain P3® relieves pain caused by misalignment of the kneecap (patellar femoral syndrome) or tracking issues.
  • GenuTrain A3® is designed for degenerative knee pain such as osteoarthritis, middle knee injuries or pain on the inner side of the knee.
  • GenuTrain S® is best if you suffer from more advance osteoarthritis of the knee, rheumatoid arthritis, bone-on-bone arthritis or MCL/LCL ligament injuries.
