Arthroscopic Rotator Interval Closure in Shoulder Instability Repair

Study Title: Arthroscopic rotator interval closure in shoulder instability repair - a prospective study

Objective: To evaluate the effect of arthroscopic rotator interval closure (ARIC) on patients with recurrent shoulder dislocations undergoing arthroscopic bankart repair (ABR) in terms of recurrence, rehabilitation and function.

Hypothesis:

1. Although Hyperlax patients undergoing ABR have higher incidence of recurrent shoulder dislocations than those without hyperlaxity, adding ARIC will lower the recurrent dislocation rate.
2. Patients with arthroscopic bankart repair (ABR) and ARIC are slower in gaining the range of motion (ROM) but within 6 months are equal to those with ABR only.

Inclusion Criteria:

• Age 16-40 years old
• Anterior Shoulder instability
• Hyperlaxity (general and shoulder laxity)

Exclusion Criteria:

• Previous humerus/glenoid fracture
• large bony "Bankart"
• Previous shoulder operation
• Adhesive capsulitis-Habitual dislocations
