The system is easy to don and doff (put on and take off), providing unparalleled comfort and security. During clinical testing by WillowWood in the USA, amputees repeatedly commented that they could put the system on at the start of their day and no longer needed to adjust their sockets repeatedly throughout their day. The second overwhelmingly reported feedback was that the airtight seal of the system did not break. Amputees could comfortably move (transition from sitting to standing, walk, run, ride a bicycle or motorcycle) with maintained vacuum, and did not experience any movement of the socket.

The WillowWood One Transfemoral System includes a fabricless Alpha Liner (choice of a SmartTemp® or Duo model) , a gel sock, a seal, and an optional elevated vacuum LimbLogic® system, along with the definitive socket and removable brim.
Diagnostic sockets for this system are created and fitted by prosthetic clinicians. Once the diagnostic socket is fit, the final, modified diagnostic socket is sent to WillowWood (in the USA) for fabrication of the removable brim and definitive socket. In Australia and New Zealand, the definitive socket has a 12-18 day lead time after receiving the final diagnostic socket at Massons Healthcare. This is a no-hassle process as shipping and socket fabrication are part of the WillowWood One Transfemoral System package. By teaming up Massons Healthcare with WillowWood’s Custom Solutions team in the USA, clinicians and their patients can be certain of receiving an air-tight definitive socket.

Clinician Testimonials:

“I have been an amputee for 33 years and have worn several different styles of sockets. I was able to beta trial the WillowWood One socket and have had very favorable results. The technology of the donning sleeve [the One Gel Sock] against the socket allows for uniform vacuum and suspension throughout the socket. I can attest to the fact that this socket has given me a true feeling of connection between my limb and the prosthesis.”

-Jeff Quelet, CPO, LPO, Ability Prosthetics & Orthotics, Inc.

“On follow-up status post 6 weeks WillowWood One delivery, patient Bob is doing great – not one complaint! He has been an amputee for ten years and gave up using his prosthesis three years ago due to poor-fitting sockets. He and his family are thrilled about his increased functional level over the past four weeks.”

–Aaron Moles, L/CP, Prosthetix Shop LLC

Patient Testimonials:

“Having just received the new “One” System, I have to say that it is absolutely the best leg I have had in the 18 years of wearing prosthetics. I’ve been wearing it for a few weeks and am extremely impressed by the comfort it provides, as well as the very strong suction system that keeps my residual limb in the socket. The fit, look, and quality are all top notch! I can see already that I will have much, much less of a problem in my work, which requires extreme ambultion all day long. Your system has proven to be just the thing I needed to get on track. Thank you so much!”

-Ralph N., Transfemoral Amputee, New Jersey
