title: [Posttraumatic arthritis of the glenohumeral joint. Joint-preserving therapy options].
abstract: BACKGROUND
  The management of glenohumeral osteoarthritis in younger patients with high activity levels remains a challenge to orthopedic surgeons. The clinical results of joint replacement surgery are commonly unsatisfactory in this particular cohort with the associated problem of limited longevity of the implant.
  
  
  OBJECTIVE
  This paper reviews the indications, techniques and outcomes of joint-preserving arthroscopic surgery for the treatment of osteoarthritis of the shoulder.
  
  
  METHODS
  A selective literature search was performed and personal surgical experiences are reported.
  
  
  RESULTS
  Besides significant pain reduction, improved range of motion and increased patient satisfaction, arthroscopic surgery can delay the need for total shoulder arthroplasty. A comprehensive approach that addresses all concomitant pathologies of the shoulder joint is of particular importance. Recent studies have shown that a glenohumeral joint space of less than 2 mm predicts significantly poorer results with arthroscopic therapy.
  
  
  CONCLUSIONS
  Arthroscopic procedures are a good option to treat young, active patients with osteoarthritis of the shoulder. Patient selection and setting a consensus for appropriate preoperative expectations are of particular relevance.
