How Often Should You Replace Your Prosthetic Device?

Prostheses are more than medical tools; they are daily companions that support movement, comfort, and independence. Just like shoes or eyeglasses, these devices don’t last forever. Over time, prostheses experience wear and tear, or there may be changes in your body, or shifts in your mobility needs. Knowing when to repair or replace them is essential for maintaining safety, comfort, and overall health.

In many low-income countries, getting a prosthetic limb is only the first step; knowing how to keep it working is another challenge. A study by Kam and colleagues spoke to prosthetists and discovered a common problem: many people who use prosthetic devices don’t know where to go when their limb needs repair or adjustment.³ As a result, prosthetic users continue using uncomfortable or broken devices, which makes performing activities of daily life difficult.¹ On top of that, tough weather and rough roads make it even harder for users to reach services.³ This shows that it’s not just about giving someone a prosthesis, it’s about making sure they have continuous care and clear support along the way. In this blog, we explore how often you should replace your prosthesis, the warning signs to watch for, and why regular check-ups matter.

General Replacement Timeline

Device Type	Average Repair Time	Average Replacement Time
Prosthetic Limb (Specifically lower limb prostheses)	237 days or approximately 7 months and 21 days 2	727 days or approximately 2 years 2

Note: These timelines may vary depending on usage, activity level, and changes in your physical condition.

Key Signs It’s Time for a Replacement

1.     Discomfort or Pain

If your device starts causing pain, pressure points, or skin irritation, it may no longer be aligning properly with your body.

2.     Visible Damage or Wear

Cracks, loose joints, worn padding, or broken straps are clear indicators that your device is losing functionality and safety.

3.     Changes in Your Body

Our bodies naturally change due to weight gain, weight loss, muscle growth, swelling, or ageing. Even a small change can affect how your device fits.

4.     Decreased Function or Performance

If daily activities like walking, climbing stairs, or standing feel more unstable or difficult, your device may no longer support your mobility needs.

Why Regular Check-Ups Matter

You shouldn’t wait until your device fails to seek help. Routine assessments every 6–12 months allow clinicians to adjust alignment, replace worn parts, and ensure proper fit. In children, athletes, or highly active users, check-ups may need to be more frequent.

At TRUCARE, we often find that simple adjustments, not full replacements, can bring back comfort and function.

Factors That Influence Replacement Frequency

• Activity Level: Athletes and highly active users will wear out devices faster.

• Environmental Conditions: Exposure to heat, moisture, sand, or water impacts device lifespan.

• Age & Growth (Children): Growing children often need replacements annually.

• Device Material & Technology: Higher-quality or advanced prosthetics may last longer but still require maintenance.

What You Can Do to Extend Device Life

Clean and care for your device as instructed

Avoid extreme conditions (heat, heavy impact, etc.)

Report issues early, don’t wait until the device breaks

Attend all follow-up appointments

When in Doubt, Visit Your Clinician

Even if you’re not feeling discomfort, an annual review ensures your device continues to meet your mobility goals. A poorly fitting or worn-out device can lead to joint pain, back problems, and reduced independence.
