Summary
This study details an arthroscopic technique for repairing anterior-inferior labral tears, common in young athletes with shoulder instability. The minimally invasive approach offers effective glenohumeral stabilization with good return-to-sport rates.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Arthroscopy
Background:
- Anterior glenohumeral instability is prevalent in young athletes, often resulting from dislocations or subluxations.
- Bankart lesions (anterior inferior glenoid labrum avulsion) occur in over 90% of these events.
- Surgical intervention is considered for persistent instability or high redislocation risk.
Purpose of the Study:
- To present a technique for arthroscopic anterior and inferior labral repair.
- To demonstrate a minimally invasive solution for glenohumeral stabilization.
Main Methods:
- Procedure performed in the lateral decubitus position.
- Creation of a second anterior portal for improved joint access.
- Arthroscopic preparation of the labrum and glenoid rim, followed by anchor placement for labral fixation.
Main Results:
- Successful arthroscopic fixation of anterior-inferior labral tears.
- Return-to-sport rates for contact athletes range from 80% to 100%.
- Recurrent instability rates are between 5% and 20%.
Conclusions:
- Arthroscopic anterior-inferior labral repair is effective for minimally invasive glenohumeral stabilization.
- Optimal portal placement, labral mobilization, and glenoid preparation are crucial for successful healing.
- This technique is suitable for patients with minimal glenoid bone loss.
