title: Can puncture increase the risk of intra-articular adhesion in the temporomandibular joint?
abstract: OBJECTIVE
  This study aims to compare the incidence and severity of intra-articular adhesion under arthroscopy between patients with and without a history of joint puncture.
  
  
  METHODS
  Eighty-nine patients with internal derangements of TMJ who underwent arthroscopic disc repositioning and suturing surgery from February 2008 to September 2008 were included in this study. Patients were divided into 2 groups based on whether the patient had undergone joint puncture before surgery or not. The diagnosis of intra-articular adhesion was made according to the manifestation under arthroscopy. Incidence and severity of intra-articular adhesion between these 2 groups was compared.
  
  
  RESULTS
  The incidence of intra-articular adhesion in the patients with a history of puncture was 69.23%, which was higher than that in the patients without a history of puncture (24.36%). The difference was statistically significant (P < 0.05). The incidence of severe adhesions in patients with a history of joint puncture was also higher than that in patients without a history of puncture (26.09% vs. 2.56%, P < 0.01).
  
  
  CONCLUSIONS
  Puncture may increase the risk of intra-articular adhesion in patients with internal derangement.
