📍 Electrode Placement for Knee Pain
Placement by Condition
General Knee Pain
Place one pad on the inner thigh (2" above knee) and one on the outer thigh. Add a second pair below the kneecap if using 4-channel.
Knee Arthritis
Position pads above and below the kneecap on both sides. This surrounds the joint for maximum relief.
Post-Surgery
Place pads around (not on) the incision site. Use low intensity initially and gradually increase.
Tips for Knee TENS
- Use smaller electrode pads (1.5"x1.5") for precise placement
- Choose rechargeable/portable units for use during daily activities
- Low frequency (2-4 Hz) works best for chronic arthritis
- Apply while seated or lying down with knee slightly bent
TENS for Different Knee Conditions
🦴 Osteoarthritis
Use low frequency (2-4 Hz) for 30 mins, 2-3x daily. Most effective for chronic pain management.
🏃 Runner's Knee
Higher frequency (80-100 Hz) for acute pain. 15-20 min sessions before/after activity.
🔧 Post-Surgery
Start 2-3 weeks after surgery. Low intensity, gradual increase. Reduces medication needs.
🩹 Meniscus Injury
Place pads above and below joint line. Moderate frequency (40-60 Hz) for 20 min sessions.
Frequently Asked Questions
Where do I place TENS pads for knee pain?
Place two electrode pads on either side of the kneecap (not directly on it). For arthritis, position pads above and below the joint. For inner knee pain, place one pad on the inner thigh just above the knee and one on the inner calf below. Keep pads at least 1 inch apart.
Can I use TENS for knee arthritis?
Yes, TENS is very effective for knee arthritis. Studies show it can reduce osteoarthritis pain by 30-50%. Use low frequency (2-4 Hz) settings for chronic arthritis pain, which helps release endorphins. Sessions of 20-30 minutes, 2-3 times daily work best.
Is TENS good after knee surgery?
TENS is excellent for post-surgical knee pain and is often recommended by physical therapists. Wait until incisions are fully healed (usually 2-3 weeks). Start with low intensity around the surgical area. It can reduce the need for pain medication during recovery.
How often can I use TENS on my knee?
You can safely use TENS on your knee 3-4 times daily for 20-30 minutes per session. For acute pain, you can use it more frequently. Take breaks of at least 1 hour between sessions and check skin for irritation from electrode pads.
