ArthroCare says Coblation equal to mechanical shaver in treatment of torn cartilage

By Elaine Rigoli

Tampa, Fla., April 27 - ArthroCare Corp. announced study results published in this month's Journal of Arthroscopy and Related Surgery show the use of low-temperature bipolar radiofrequency, known as Coblation technology, preserves the same amount of healthy cells in a bovine model as a mechanical shaver in the treatment of the meniscus, or torn cartilage.

The study also indicated that Coblation technology may result in a smoother surface when compared to the shaver.

The study tested three different combinations of treatment methods in the meniscal debridement of six bovine knees and compared the results to an untreated control group, according to a news release.

The different treatment combinations included Coblation technology alone, a basket punch followed by Coblation technology and a basket punch followed by mechanical shaver.

The cell viability was 96% to 98% in all specimens. The data also indicated that meniscal debridement with Coblation did not extend to underlying cartilage.

This follows another study presented in January at the International Cartilage Repair Society symposium indicating that Coblation may aid in the repair of the avascular region of the meniscus of rabbits following injury and suture repair, the release said.

Austin, Texas-based ArthroCare is a medical-device company that develops, manufactures and markets minimally invasive surgical products.
