Laser Therapy for Knee Arthritis Pain in Hinsdale: Is Class IV Laser Right for You?

Short answer: Class IV laser therapy uses high-powered light to calm inflammation and pain deep in the knee. It’s drug-free and needle-free, and you can go straight back to your day afterward. Research on knee osteoarthritis is encouraging. A 2024 meta-analysis found laser reduced knee pain more than placebo, and a 2026 trial found high-intensity laser plus exercise beat ultrasound plus exercise. At Adisi Health Center in Hinsdale, Dr. Steve Petzel uses the 40-watt LightForce XLi, usually alongside exercise and other therapies.

What is Class IV laser therapy?

Class IV laser therapy, also called photobiomodulation, delivers infrared light into tissue. Cells absorb that light, which boosts energy production, calms inflammatory signals, and improves local circulation.

The LightForce XLi at Adisi Health Center:

• Delivers up to 40 watts of power, compared with under 0.5 watts for typical Class 3 “cold” lasers
• Uses two wavelengths (810 nm and 980 nm) to reach both shallow and deep tissue
• Reaches the knee joint in 10–15 minute sessions
• Is FDA-cleared

Can laser therapy help knee arthritis pain?

Here’s what recent, peer-reviewed research shows:

• Laser vs. placebo (2024 meta-analysis). A review of 10 placebo-controlled trials with 542 patients found photobiomodulation reduced knee osteoarthritis pain at rest more than placebo, with a moderate effect. (Oliveira et al., Physical Therapy, 2024. PubMed 38775202)
• High-intensity laser vs. ultrasound (2026 trial). In a randomized trial of 66 adults with knee osteoarthritis, high-intensity laser plus exercise improved WOMAC pain and function scores far more than ultrasound plus exercise: a 40-point drop vs. 8 points. The benefits held 12 weeks after treatment ended. (Ninlerd et al., Lasers in Medical Science, 2026. PubMed 42709245)

Bottom line: Laser is a drug-free, low-risk option for knee arthritis pain, and the research supports pairing it with strengthening exercise.

Who is a good candidate for laser therapy for knee pain?

• Adults with knee osteoarthritis or “wear and tear” knee pain
• People with patellar tendonitis or runner’s knee
• Anyone who wants to cut back on pain pills or avoid or delay injections
• Active adults who want treatment with no downtime

Who shouldn’t have laser therapy?

Dr. Petzel reviews your health history before treatment. Laser therapy is generally not applied:

• Over the abdomen or low back during pregnancy
• Over known or suspected cancer
• Directly toward the eyes (everyone wears protective glasses)
• Without first checking medications that make you sensitive to light

A knee that is hot, very swollen, or locking, or that was hurt in a recent fall or accident, should be evaluated before any treatment.

What is a laser therapy visit like?

1. Consultation and assessment. Dr. Petzel examines your knee, reviews your history, and sets your laser settings. Every plan is individualized.
2. Treatment. The LightForce handpiece moves over the knee, and you feel a gentle, soothing warmth. Each area takes 10–15 minutes.
3. Response. Many patients notice less pain and easier movement within the first 1–3 sessions. Chronic problems usually need more visits.
4. Ongoing plan. Sessions are typically 2–3 times a week. Dr. Petzel tracks your progress and may combine laser with chiropractic care, EMTT, or TECAR.

Pricing: $115 per session, $920 for 10 sessions ($92 each), or $1,700 for 20 sessions ($85 each). HSA and FSA are accepted. Laser is also included in the Adisi Wellness Membership.

Frequently asked questions

Does laser therapy for knee arthritis hurt?
No. Most people just feel comfortable warmth.

How many laser sessions will my knee need?
It depends on your knee. Most patients need 10–20 sessions, which is why packages are offered. Dr. Petzel will give you a recommendation after your exam.

Is Class IV laser the same as cold laser?
No. The LightForce XLi delivers up to 40 watts, far more than Class 3 cold lasers under 0.5 watts. That lets it reach deeper tissue in less time.

Can laser therapy replace knee replacement?
Laser can’t regrow cartilage. For many people, though, it’s one way to manage pain and stay active. Ask Dr. Petzel whether it fits your situation.

Does insurance cover laser therapy?
Most plans don’t cover Class IV laser. It’s cash-pay at Adisi, and HSA and FSA are accepted.

Can I combine laser with other treatments?
Yes. Dr. Petzel often pairs laser with exercise, chiropractic care, EMTT, or TECAR.
