title: [Effect of arthroscopic debridement for adolescent ankylosing spondylitis with early hip-joint disease].
abstract: OBJECTIVE
  To study the effect of arthroscopy debridement for adolescent ankylosing spondylitis (AS) with early hip-joint disease.
  
  
  METHODS
  A total of 22 cases (26 hips) of adolescent AS were recruited. There were 15 males and 7 females. The distribution was as follows: left side (n = 10), right side (n = 8) and bilateral (n = 4). The average age was 16 (14 - 19) years old. The procedures included adhesion relief of hip joint, removal of hyperplasic synovial membrane, degenerated cartilage debris and repairing exfoliated debris or exposed subchondral bone on hip joint.
  
  
  RESULTS
  All patients were followed up for an average of 26 (6 - 84) months. Most patients experienced pain relief, restored function and the range of motion. According to Harris hip joint score and VAS pain score evaluation system, the outcomes were excellent (n = 6) fair (n = 14) and poor (n = 2). There was no case of total hip replacement.
  
  
  CONCLUSIONS
  Arthroscopic debridement for adolescent ankylosing spondylitis with early hip joint disease is effective to improve joint motion and relieve pain.
