From: Procaine and saline have similar effects on articular cartilage and synovium in rat knee
The articular cartilage and epiphyseal plates of experimental groups. The extracellular matrix showed similar glycosaminoglycan content in saline and procaine groups both in the articular cartilage and epiphyseal plates. a–e and f–j show the articular cartilage of knee joints in saline and procaine, respectively. k–o and p–u show the epiphyseal plates in saline and procaine, respectively.
