[Aims] To evaluate the short-term efficacy of arthroscopic iliac crest bone grafting of the glenoid for recurrent dislocation of shoulder joints.[Materials and Methods]From 2013.03～2019.03, total 27 cases accepted arthroscopic iliac crest bone grafting of the glenoid for recurrent dislocation of shoulder joints，Male:24，Female:3, age 18～54years，average:26.7years. Glenoid defect: 0%～30%，average:10.3%. All combined with Hill-sacks defects. No multiple ligament laxity. Following time: 6～38months，average:13.3months. Assess patient satisfaction, re-dislocation rate, re-entry and work, fear test positive rate, and shoulder UCLA and Constant scores.[Results]All 27 patients were followed up. Bone graft healing time 6weeks～8 weeks.No complications occurred. Patient satisfaction rate of 100%, no re-dislocation of patients. All patients have returned to pre-injury work or exercise state, fear test negative. Last follow-up patients have returned to pre-injury work or exercise state, fear test negative. Last follow-up shoulder UCLA score 34.2 ±0.7, Constant score 91.5±2.3. Conclusion: The short-term efficacy of the treatment of recurrent dislocation of shoulder joints under the arthroscopic iliac crest bone grafting of the glenoid was satisfactory, and there were no re-dislocation patients, and the long-term effect needed further follow-up results.
