As an above-knee amputee, I am sharing experience and giving advice for amputees on prosthetic legs and living life as an amputee.

The key to a good prosthetic leg for above-the-knee amputees is proper socket fit, particularly with a short stump. See how I use muscle contraction to hold the prosthetic socket of my above-knee prosthesis.
Go to Prosthetic Socket Fit.

Read my article on what I believe really matters in terms of prosthetic knee joints, and how I compare mechanical and microprocessor prosthetic knees.
