Summary
This study presents a 4-portal arthroscopic stabilization technique for posterior shoulder instability. The technique showed no recurrence of instability and high patient satisfaction, suggesting improved glenoid access.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Arthroscopy
Background:
- Posterior shoulder instability is a challenging condition.
- Arthroscopic techniques are evolving for improved outcomes.
- Previous methods have recurrence rates below 12%.
Purpose of the Study:
- To present a novel 4-portal arthroscopic stabilization technique for posterior shoulder instability.
- To evaluate the efficacy and safety of this technique.
- To assess patient satisfaction and functional outcomes.
Main Methods:
- Arthroscopic posterior labral suture with anchors and capsular plication using a 4-portal approach.
- Study included 11 patients (13 shoulders) with posterior instability.
- Average follow-up period of 34 months.
Main Results:
- No complications or recurrence of instability were reported.
- Moderate loss of range of motion in 4 shoulders and moderate pain in 2 shoulders.
- All patients reported satisfaction with the outcome.
Conclusions:
- The 4-portal arthroscopic technique facilitates access to the posteroinferior glenoid.
- This technique appears to reduce the rate of postoperative instability.
- Outcomes for pain and range of motion are comparable to existing literature.
