Reflex

A three-site knee clinic group, trading as Reflex Knee Specialists, offering non-surgical knee treatments including injections of cells taken from the patient's own fat.

Overview

The Portland practice listed here now operates under the name Reflex Knee Specialists, with its website at reflexknees.com. The site describes a small group of clinics focused narrowly on the knee, listing three locations: Portland, Oregon; Bellevue, Washington; and Tempe, Arizona. The Bellevue address given on the site is 1918 152nd Avenue NE, Suite 200, Bellevue, Washington.

The clinic's stated purpose is to treat knee osteoarthritis and knee pain without joint replacement surgery. Alongside cell-based and platelet injections, the site names joint fluid therapy (injection of hyaluronic acid, a lubricating gel), ozone therapy, diagnostic ultrasound, knee bracing and physical therapy, and also discusses knee replacement so that patients can compare options.

On cell therapy, the site states that it harvests cells from adipose (fat) tissue rather than bone marrow, and argues that fat yields far more cells per gram and is less painful to collect. Notably, and to its credit, the site also sets out clear limitations: it states that large randomised controlled studies have not been conducted, that the treatment is considered experimental and is not approved by the United States Food and Drug Administration, and that insurance does not cover it. Those statements should be weighed carefully by anyone considering treatment.

The site names several physicians, including Russ Riggs, Ryan Riggs and Shannon Corrigan, as well as nursing and anaesthesia staff. It does not publish prices, a founding year, or any languages other than English, and the locations page the site publishes gives a full address only for the Bellevue clinic — a prospective Portland patient would need to confirm the Oregon address and that it is still open.

Cost and Payment
