BoneFoam Zero Degree Knee | Rehab After Knee Replacement, MCL, ACL Surgeries | Helps Improve Extension, Mobility & Flexibility | Passive & Gravity-Assisted Extension | Made in USA | Graphics May Vary

Excellent for someone who has just had knee surgery; it keeps your leg straight.

It does its job if you’ve had knee replacement surgery but awkward

excellent for use post knee replacement. comfortable in using for knee extension that’s key to rehab recovery after having knee surgery. Little high in pricing, but worth it to get leg extended fully.

I never write a review but I had to for this pillow. Recebtly had ACL reconstruction surgery, and my left leg naturally falls to the left. No matter how many pillows I would put, the leg would just give up. It’s amazing how I can take a nap with my whole leg being straight. I know for a fact this pillow will help me with a speedy recovery.

I refer to this as my “torture pillow”. I am currently pre-TKA but I’ve already lost some extension in the leg so I’m using this preop to help maximize the extension I can get before surgery in hopes that after surgery getting back to full extension will be quicker. It’s no fault of the pillow that my knee hurts during the process so I feel bad for calling it my “torture pillow”. I’m using it on my good (well, not as bad is more like it) leg as well sometimes and it doesn’t hurt at all on that leg. I do find the foam uncomfortable/scratchy on bare skin but use a T-shirt as a pillow case and problem solved. UPDATE I’m still preop, but after a couple of weeks of using the pillow it no longer hurts. At first I could not use if for even 15 minutes without severe discomfort but now I can use it for an hour straight no problem with only slight discomfort. Seems to be working to regain extension in my knee! POSTOP UPDATE I am just shy of six weeks post TKA. Using the pillow for more than a minute at a time has been very painful and challenging, but I have worked my way up to 10 minutes (albeit uncomfortable minutes) and plan to keep working on it. The pillow really helps me get into a stable position to work on my knee extension and I would recommend it to anyone needing to improve their knee extension. I will update again in another few weeks or so. ANOTHER UPDATE just over 3 months postop and it is getting less and less uncomfortable and my leg straightens pretty well. When I’m sitting on the ground with my leg straight out in front of me (without the ZDKP), I still can’t contract the front of my leg hard enough to lift my heel off the ground like I can with my non-surgical leg. I’m hoping continued use of the ZDKP (as well as my strengthening exercises) helps to achieve that. Will do another update in another few months.

My wife found this online and the design seemed well thought and functional. Today is day 6 post surgery and my Physical Therapist came by to help me do exercises and evaluate my progress. He was amazed that my range of motion is already back to zero on the low end. I let him know that most of that had come from using this device, just elevating my leg until the back of the knee was elevated. He had never seen one of these and said it had replaced two or three less comfortable exercises normally used to reach zero. Thank you for a great product that even exceeds the claims on the website!

It is as advertised. But it is crazy expensive for what it is. I mean, it is just a piece of foam. The clinic that did my knee replacement was adamant I get something that does what this does but the objective could be accomplished with something home made real easy. I mean, it is a block of foam with a relief cut in it that is a one size fits all approach. It was tight for me. It would be high but tolerable at half the price.

It's gonna hurt to keep your knee straight, but do it anyway. Using pillows for one surgery left me with a contracture. Used this after my redo and kept my knee extension. Don't use all day though. Need to take breaks from foam pressing into ankle.

Over priced, but works well.
