Whether your knee pain is from osteoarthritis, a meniscus injury, runner's knee, or post-surgical recovery, red light therapy can help. The 830–850nm near-infrared wavelength penetrates deep enough to reach joint tissue, reducing inflammation and stimulating cellular repair.
What the Research Says
Knee pain is one of the most-studied applications of red light therapy. Key findings:
- Multiple RCTs show clinically meaningful pain reduction in knee osteoarthritis after 4–12 weeks of NIR therapy.
- A 2018 meta-analysis concluded that RLT is an effective treatment for knee OA pain.
- Studies on post-surgical knee recovery show faster healing and reduced pain medication use with RLT.
- Patellofemoral pain syndrome ("runner's knee") responds well to RLT, with multiple small studies showing improvement.
The Knee Pain Protocol
- Position the device 6 inches from your knee. For panels: sit with knee 6 inches from the panel. For wraps: secure directly to the knee.
- Treat both sides of the knee. Front (quad tendon area) and back (popliteal area) — 10 minutes per side.
- Treat daily for acute pain, 3–5x per week for chronic. 15–20 minutes total per session.
- Combine with gentle movement. Walking, swimming, or stationary cycling enhances RLT effects.
- Track pain and function. Note daily pain (1–10) and any activities you couldn't do before.

Protocols by Knee Condition
Osteoarthritis
10–15 minutes per knee, daily or 5–6x per week. Most users see meaningful improvement after 4 weeks. Combine with low-impact exercise.
Meniscus Injury
10–15 minutes per knee, 2x daily for acute phase, then daily. RLT reduces inflammation but cannot repair a torn meniscus — surgery may still be needed.
Post-Surgical Recovery
Start RLT 2–3 days post-surgery (with surgeon's approval). 10 minutes per knee, 2x daily for the first 2 weeks, then daily. Faster recovery and reduced scar tissue.
Patellofemoral Pain (Runner's Knee)
10 minutes per knee, daily. Focus on the front of the knee (patella area). Combine with strengthening exercises for the quad and hip muscles.
Tendonitis (Patellar Tendon)
10–15 minutes per knee, daily. Focus on the area just below the kneecap. Tendonitis responds well but requires patience — 6–8 weeks for full relief.
