active AK knee choices

Lane Ferrin

Dear Colleagues,

I am seeing a 20 yr. old man for a new prosthesis, he has a near KD residuum

and has broken everything I have put on him. He needs hydraulic swing

control and wants a vert. shock pylon and Flexwalk performance with better

durability. He has had the best luck with a titanium Blackmax with the knee

axis bushings machined out and replaced with sealed motorcycle wheel

bearings. He destroyed an Endolite High-activity frame in 6 months time.

Any suggestions for durable components from your experience?

Thanks,

Lane Ferrin CP
