A prosthesis isn’t designed to last forever, and neither is its fit. If you’ve been using the same device for years, your body, activity level, or prosthetic components may have changed. Being aware of the signs you need a new prosthesis can help you stay comfortable, safe, and active.

Here are five clear signs it may be time for an upgrade.

1. You’re Experiencing More Discomfort Than Usual

If something that used to feel fine now causes pain, that’s your body telling you something. Discomfort isn’t something you should just accept.

2. Your Socket Feels Loose or Unstable

If your leg feels like it’s shifting, rotating, or not holding you securely, your fit has likely changed. That’s not just uncomfortable—it’s unsafe, and it’s one of the most common signs you need a new prosthesis.

3. You’re Getting Skin Irritation or Breakdown

Your skin is one of the first indicators that something is off. Blisters, redness, or open areas should never be ignored.

4. Your Activity Level Has Changed

If you’re more active now than when you first got your prosthesis, your current setup may be holding you back. On the flip side, if things have slowed down, your needs may have changed in a different way.

5. Your Components Are Worn Out

Just like anything mechanical, prosthetic components wear down over time.

Typical timelines:

• Feet: around 3 years
• Knees: around 5 years

If you’re pushing past that, performance may not be what it used to be.

Final Thought

A new prosthesis isn’t about starting over—it’s about moving forward. If your current setup isn’t helping you live the way you want, it’s worth exploring your options. Are you noticing any of the signs it’s time for a new prosthesis? Then contact Leimkuehler Orthotic-Prosthetic Center Inc.
