📍 Electrode Placement for Knee Pain

Placement basics

Use the device manual first

Follow the pad-placement diagram supplied for your exact device. A clinician can help you adapt it to your symptoms and medical history.

Avoid restricted areas

Do not place pads directly over the kneecap, over broken or irritated skin, or in any area the manual identifies as unsuitable.

After surgery

Get clearance from your surgical team before use. Do not place pads on an incision or any area your care team has told you to protect.

⚠️ Do not place pads directly on the kneecap or open wounds.

Tips for Knee TENS

  • Check the included pad size and replacement availability before buying
  • Use a device only as the manufacturer manual directs
  • Start only after reviewing warnings and contraindications
  • Ask a clinician for guidance after an injury or surgery

Questions to Ask Before Choosing a Device

🦴 Medical history

Ask a qualified clinician whether a TENS device is appropriate for arthritis or other ongoing knee symptoms.

🏃 Activity-related pain

New, severe, or persistent pain deserves a diagnosis and a recovery plan rather than self-treatment alone.

🔧 Post-surgical recovery

Follow your surgeon's or physical therapist's instructions before considering any electrical-stimulation device.

🩹 Injury concerns

Confirm the device warnings, recommended placement, and next medical steps with a qualified professional.

Frequently Asked Questions

Where do I place TENS pads for knee pain?

Use the placement diagram in the device manual. Do not place pads directly over the kneecap, on broken skin, or in any location the manufacturer warns against. Ask a clinician for personalized placement advice.

Can I use TENS for knee arthritis?

Some people explore TENS as a non-drug comfort option, but results vary and it does not treat arthritis itself. Review the manual and ask a qualified clinician whether it is appropriate for you.

Is TENS appropriate after knee surgery?

Only use a TENS device after your surgical team approves it. Follow the postoperative plan and manufacturer instructions, and do not use pads on an incision, open skin, or an area your clinician advises against.

How often can I use TENS on my knee?

Follow the manufacturer instructions and any guidance from your clinician. Stop use if you notice skin irritation, worsening symptoms, or another concerning reaction.
