Single-stage procedures for treatment of traumatic patellar osteomyelitis: A retrospective study of 21 patients.

Introduction: We herein report on a series of 21 patients with traumatic patellar osteomyelitis treated by single-stage surgery, and discuss the specific application of single-stage procedures for traumatic patellar osteomyelitis.

Methods: We retrospectively reviewed the medical records of 21 patients with traumatic patellar osteomyelitis treated in our hospital from January 2010 to April 2018. In a single-stage surgery, aggressive debridement was performed together with application of a tissue flap, especially a gastrocnemius flap (for repair of skin/soft tissue defects and treatment of extensor mechanism defects), and internal refixation of the patellar fracture.

PPAR-γ agonist pioglitazone alleviates inflammatory response induced by lipopolysaccharides in osteoblast cells.

Osteomyelitis is an acute or chronic inflammatory bone disease with a high disability rate. As an anti-inflammatory factor, peroxisome proliferator activated receptor-γ (PPAR-γ) is not only implicated in a variety of inflammatory responses but also regulates osteoblast differentiation and bone mass. However, the role of PPAR-γ in osteomyelitis is not fully understood.
