Outcomes of arthroscopy in recurrent shoulder instability at Viet Duc University Hospital

Abstract Introduction: This study aims to assess the results of patients with recurrent shoulder dislocation treated with arthroscopic Bankart repair. Patients and Method: 31 patients (26 males and 5 females, with an average age of 28.7) were treated with arthroscopic Bankart repair from 2017 to 2018. Those with multidirectional instability, posterior shoulder instability and more-than-25% Hill-Sachs defects, along with those who had prior shoulder surgeries were excluded. Average follow-up time after surgery is 15.13 months. Frequency of pre-operative dislocation, post-operative dislocation, functional status and daily activity performance were evaluated. The results were assessed using CONSTANT score. Results: One patient had post-operative dislocation (3.23%). One patient had post-operative joint adhesion (3.23%). Assessment using CONSTANT score showed an excellent result in 67.4%, good in 12.9%, moderate in 12.9% and average in 6.46%. There was no case with poor result. One patient had post-operative dislocation due to a sport injury. Conclusions: Arthroscopic repair is a modern technology, and is being used widely in diagnosing and treating shoulder lesions. This study shows that arthroscopic repair for recurrent shoulder dislocation may bring good result for patients. Keywords: Shoulder instability, arthroscopy, Bankart.
