This feature ensures even and adjustable compression, allowing users to tailor the level of support to their specific needs.The open patella design of the immobilizer helps alleviate direct pressure from the patella, enhancing overall comfort. Additionally, this design aids in stabilizing the patella, promoting better protection for individuals with knee injuries.Overall, the Alpha Medical Three Panel Knee Immobilizer is designed for treating knee injuries, particularly those affecting the ligaments or causing severe damage to the soft tissue of the leg.

Review: Excelente producto,muy buena calidad.
Review: I’m not sure if I have a fracture yet but it helps the pain I’ve had under my knee for about a week and a half, so I’m just wearing it for comfort for now. I’ve had other (longer) immobilizers, one that went from the top of my leg to my ankle and it was difficult to apply by myself and kept slipping down no matter how tight I adjusted it. It was also difficult to adjust the panels to fit my legs, which were much thicker almost two years ago than they are now. But this immobilizer can also be adjusted, not sure if some people aren’t aware of how these 3 panel immobilizers work, but they usually come on the smallest size and you have to separate the panels and put them back together so that they can fit a larger leg. They usually come with instructions, but I wasn’t given the instructions from the hospital when I got my first immobilizer, so it was a while before I figured it out. This one does not slide down my leg (I’m wearing it without any clothes underneath). And it immobilizes my knee and prevents the hyperextension which is something I do naturally and causes pain since I sustained some kind of injury. I’m seeing an orthopedic surgeon this week so I will hopefully have X-rays taken at the very least and get an exam that will give me an idea of what my latest problem is.

*by A***R on 20 May 2025*

I used this after I fractured my leg (minor fracture) and it worked well for support and immobilization. The one I took home from the hospital was too large (5 straps). I was able to become mobile quicker by using this instead of crutches. The only issue I had was: the Velcro and straps were less reliable with time.
