Product Questions

I tore my MCL around 7 months ago but did not require surgery. I have since gotten back into running around 3 or 4 months ago and increased my weekly distance goal from 5mi/week to 10+. However, while the MCL still feels "odd" once in awhile it is not the major source of pain and now it seems that I have developed runners knee. Considering that winter is upon us and I also snow ski and snowkite I figured I had better get a brace. Is this the right brace?

Thank you for contacting DJO. The DonJoy Drytex Hinged air Knee Brace will work for you because it will give you the medial support from the hinges and the patellar dohut will help with the anterior knee pain. If you have any other questioins please let us know

I have had many reactions to the neoprene in other knee braces but need a brace as I have Chondromalacia patellae, patellofemoral pain, and have sprained my mcl, and lcl. would this knee brace work for me? or what else would you suggest. the last time I wore a knee brace I had a rash that I had to take steriods to get rid of.
thank you

This brace will work for you. It has hinges for the MCL and LCL, a patellar buttress for the knee cap problems and it is not neoprene

Hi. I have patella tendinitis and patella femoral as well as very mobile knee caps and some instability to the LCL and PCL. I wrestle at a high level and am looking for new braces as I don't like mine. Would this be a good option?
Question by: Matt on Nov 18, 2015, 6:29 PM
The Hinged Air Knee brace will provide both patellar stability and medial/lateral control. For your injuries you could use this brace

how does this brace compare to the breg pto?
Question by: dancinonwater on Feb 1, 2011, 1:56 PM
The DonJoy Drytex Hinged Air Knee Brace is a patellofemoral brace that will stabilize you kneecap; however, the DonJoy brace most compatible to the PTO is the Tru-Pull Advanced System which had the bifurcated strap to adjust the amount of support to the needs of your knee. The Tru-Pull Advanced knee brace comes with or without hinges. Another patellofemoral brace that is unique to the market is the DonJoy Reaction brace which has the elastomeric web design. The elastomeric design creates energy dispersion across the knee for optimal shock absorption

I am looking at getting the playmaker brace. I have a multiple ligament tear in my knee and will be having ACL reconstruction surgery in the fall. I am putting off surgery because as professional guide I need to be able to lead hikes and other activities for the summer. I was thinking the drytex material would be the best choice for breath ability. Is there any reason you would recommend the neoprene one any thing else?
Question by: Erik on Mar 14, 2014, 10:51 AM
If you are looking at the Playmaker and are concerned about the material, look at the Playmaker II. You can get this brace in the spacer material which is even cooler than the Drytex. It will be more comfotable than both neoprene and drytex.
