Prospective Pilot Study of Painful Lumbar Facet Joint Arthropathy after Intra‐articular Injection of Hylan G‐F 20

Abstract

Viscosupplementation for lumbar FJ arthropathy with hylan G-F 20 is associated with modest efficacy that predominately lasts up to 6 months. Limitations include a small sample size and lack of both a control and blinding. Larger, randomized, controlled studies are indicated to better clarify its clinical safety, efficacy, and utility.
