I would like to thank everyone that responded to the original post looking for a kid proof hydraulic/pneumatic knee. It is funny though that I got more responses requesting I post the replies than I did replies. Be that as it may, I did get some useful suggestions.
One was to use an Otto Bock 3R-45 which is a scaled down version of a 3R65, which I did try. The problem was that the hydraulic cylinder is covered with a rubber boot. The hydraulic oil is cycled out of the cylinder into this boot in order to cool the oil for such a small cylinder. The cylinder seems well protected inside its mini frame but when dirt or foreign objects get in they rip the boot and all the oil leaks out.
Another was to suggest the Seattle Childs play knee with the use of an elastic extension bias because kids like this are too brutal on hydraulic/pneumatic knees. This may be the most useful reply yet because I am certainly inclined to believe that this kid will be too brutal on anything hydraulic. I am looking for something bomb proof.
Another was to cover the prosthesis with a cover that can help keep out water, mud and foreign objects such as a Daw skin. Ohh, if only I could! But it would only last about two to three days at best. This prosthesis is uncovered most of the time and there is a removable plastizote shin section that will fill out the pant leg that is used for special occasions.
Again, I thank everyone for their suggestions and wish that I would have gotten more replies.

I am working with a family and the ten year old son who is a right trans femoral amputee. I am looking to find a durable fluid control knee. He has already been through a number of knees with none of them holding up past 4 or 5 months without needing replaced. Some of these knees were:
Ohio Willow Wood, pendulum Jr.
Otto Bock, 3R-65
Century , pediatric total knee
This kid is very hard on the prosthesis by just being a kid. He roller blades, bikes, school sports. What seems to be the most destructive to the knees is his love for playing in the mud.
I am looking at replacing the knee again and would like your suggestions. I am looking at the USMC Mini Max knee as a possible choice, Have any of you used this knee?
