The key to a good prosthetic leg is proper fit of the prosthetic socket. Which depends first and foremost on the expertise of your prosthetist. Therefore it is difficult to say if your prosthetic socket fit is good or if you could have a better one. I have seen many prosthetists and more than once I had to change my prosthetist because the prosthetic socket I got was uncomfortable or even painful.
The prosthetic socket I am demonstrating in this video is unconventional because I hold this socket purely with muscle contraction in my residual limb. I do not need a silicone liner or a donning aid (to pull the stump skin into the socket). This might not work for all above knee amputees. However, the precise fitting of this socket is a demonstration of what is possible even with a short stump. This should give hope to amputees who are struggling with their current prosthetic leg. See my video to understand why this above-knee prosthetic socket is exceptional.
I give credit to my prosthetist Alexander Schwarz from Schwarz Prosthetics in Hamburg, Germany, who was patient enough to try out unconventional ways and whose expertise as a specialist for above knee prosthetic sockets is unparalleled. For me as an above knee amputee a prosthetic socket that is both functional and comfortable is a major factor for my quality of life!
In the following video I am testing my socket on difficult terrain, requiring a maximum of stability in the socket. See how it works, even with a short stump:
