Can I walk comfortably as soon as my below-knee prosthesis is made?
Usually, not straight away. For months after amputation, swelling goes down and the limb slims, so its size keeps changing — and if a stiff knee straightens, the length the prosthesis needs changes too. A below-knee prosthesis is fitted to your body over time through several check-ups and adjustments, and sometimes a new socket.
Why is the first prosthesis not the end?
With a below-knee prosthesis, comfortable walking depends on the socket — the part your residual limb sits in — fitting your body well. But for some time after amputation, the limb does not stay the same.
- Swelling — it goes down at a different pace for everyone and can linger for months.
- Muscle and soft tissue — once you start walking, the limb’s volume shrinks and the socket gradually loosens.
- Joints — if the knee had stiffened in a bent position (a contracture), straightening it changes your alignment and the length the prosthesis needs.
- Your other leg — if the knee on your other side is troublesome, early walking can be harder.
Many people who come to us for the first time expect a prosthesis to feel comfortable immediately. Because of these changes, several visits and adjustments are often needed.
One customer’s first six months
Here is how one customer’s process unfolded over six months of follow-up at Silobionic. When they first came in, several months after surgery, there was still a lot of swelling and the knee had stiffened in a bent position. The knee on the other side was also uncomfortable.
| When | Limb and walking | What we did |
|---|---|---|
| First consultation | Marked swelling, stiff knee | Started with a compression liner for swelling. As they were keen to walk soon, we cast the limb and made the first prosthesis. We explained straight-knee stretches and massage and checked in by phone along the way |
| About 1 month | The stiff knee had straightened considerably | Adjusted the prosthesis to the changes and went over rehab exercises again |
| About 3 months | Limb slimmer and less pain, but walking had not improved as much as hoped | The straighter knee had made the prosthesis effectively short, so we lengthened it |
| About 6 months | The socket had become so loose that several layers of prosthetic socks were needed | Made a new socket to match the limb’s new size |
With the new socket, our customer said nothing was uncomfortable, and they now walk on their own without a wheelchair. This is one person’s journey, though — timelines and results vary with each person’s limb and overall health.
Why is the number of sock layers a warning sign?
When the limb shrinks and leaves space inside the socket, prosthetic socks are layered to fill it. If you keep needing more layers, the socket may already be too big for you. Rather than simply adding socks, it is safer to have a check-up to decide whether the socket should be refitted — a loose socket can cause wobbling and rubbing as you walk.
What you can do while adapting
- Keep up the stretches and rehab exercises you were shown. Agree methods and intensity with your medical and rehabilitation team.
- Tell us about any pain, rubbing or red marks that linger — do not just put up with them.
- Book a check-up if you notice changes, such as needing more sock layers or the prosthesis feeling short.
- Note down which movements feel uncomfortable and when; it helps a great deal with adjustments.
That is why a long-term relationship with your prosthetist matters
A prosthesis is not a one-off purchase but something you live with for years. After we make a below-knee prosthesis, Silobionic continues to check changes in your limb at follow-up visits and advises on length adjustments or a new socket when needed. For this customer, who had nowhere else to continue exercise and care, we also called between visits to see how things were going.
Frequently asked questions
How many adjustments does a below-knee prosthesis need?
There is no set number. Several check-ups may be needed until swelling, muscle and joints settle, and if the limb shrinks a lot, a new socket may be made.
What are the signs that I need a new socket?
If it feels loose even with several layers of prosthetic socks, or you notice wobbling, rubbing or pain as you walk, the socket may no longer fit. A check-up will tell.
Can I have a prosthesis if my knee is stiff?
Often yes, but alignment and length are harder to set and early walking can be more difficult. Discuss stretching and care with your medical and rehabilitation team.
Should I push through pain to get used to it?
No. Pain or rubbing can mean the socket or alignment needs adjusting, so let us know straight away.
