title: [Effectiveness comparison between arthroscopic and nonsurgical treatments for ankle degenerative osteoarthropathy].
abstract: OBJECTIVE
  To evaluate the effectiveness of arthroscopic treatment and nonsurgical treatment on ankle degenerative osteoarthropathy.
  
  
  METHODS
  Between July 2009 and June 2011, 58 patients (58 ankles) suffering from ankle degenerative osteoarthropathy underwent arthroscopic treatment (arthroscopic group, n=28) and routine treatment (control group, n=30). There was no significant difference in gender, age, body mass index, disease duration, and degree of ankle degenerative osteoarthropathy between 2 groups (P > 0.05). Mazur score, visual analogue scale (VAS), and Tegner activity scale were used to evaluate the effectiveness.
  
  
  RESULTS
  Incision healed primarily in arthroscopic group. The patients of 2 groups were followed up 1-2 years, averaged 1.5 years in arthroscopic group and 1.6 years in control group. At last follow-up, Mazur, VAS, and Tegner scores were significantly improved when compared with the preoperative scores in 2 groups (P < 0.05), but no significant difference was found at last follow-up between 2 groups (P > 0.05). According to Mazur scoring, the results were excellent in 8 cases, good in 14 cases, fair in 5 cases, and poor in 1 case, with an excellent and good rate of 79% in arthroscopic group; the results were excellent in 6 cases, good in 15 cases, fair in 6 cases, and poor in 3 cases, with an excellent and good rate of 70% in control group; and no significant difference was observed between 2 groups (u=0.98, P=0.77). Moreover, there was no correlation between Outerbridge classification and Mazur score in patients undergoing arthroscopic treatment (r=0.18, P= 0.34).
  
  
  CONCLUSIONS
  Arthroscopic and nonsurgical treatments of ankle degenerative osteoarthropathy can both achieve good effectiveness.
