Intraarticular/Interstitial Laser Therapy

Intraarticular / Interstitial Laser Therapy

This method allows precise laser irradiation of damaged structures such as nerves, cartilage, and bone, providing an effective option for pain relief and tissue regeneration, especially in joint and spinal conditions. The procedure involves inserting a fiber-optic light conductor via an interstitial needle, up to 12 cm in length, directly into the affected tissue or joint.

Duration of a session: 20–30 minutes

Number of sessions: Chronic cases typically require 10 to 20 sessions. Acute conditions often improve after 2 to 3 sessions

Frequency: 2 to 3 sessions per week

Indications

Treating pain right at the source

By using an invasive technique, even shorter wavelengths like green, blue, and yellow can penetrate deeply into tissues, delivering targeted anti-inflammatory action.

In contrast, non-invasive laser therapy suffers significant power loss (over 70%) as the light passes through the skin, resulting in minimal energy reaching the pain’s origin. Hence, direct joint irradiation is critical for successful tissue regeneration, especially in chronic joint ailments.

Which wavelengths are used in intraarticular / interstitial laser therapy?

The following wavelengths or laser colors are used for tissue and joint irradiation, depending on the symptoms.

Blue

405/447
nm

Green

532
nm

Yellow

589
nm

Red

635/658

This targeted selection of colors promotes cellular regeneration and modulates inflammatory processes, which can significantly accelerate tissue healing.

Integrated injection therapy

The regenerative benefits of the therapy may be amplified by combining it with hyaluronic acid or platelet-rich plasma (PRP).

Here you’ll find suitable kits with blood collection tubes for PRP preparation. Using the same cannula for both injection and laser treatment minimizes discomfort by allowing just one puncture.

Accessories

The Weberneedle^® Lasercath with a puncture cannula is typically used for joint irradiation.

For regenerating superficial tissue structures, the Weberneedle^® Butterfly combined with the Weberneedle^® Lasercath is recommended as an alternative.

Intraarticular and interstitial laser therapy targets tissue regeneration precisely, whether for acute injuries, chronic conditions, or post-operative healing. Accurate positioning of the light source plays a key role in promoting lasting tissue repair.
