A biomechanical analysis of capsular plication versus anchor repair of the shoulder: can the labrum be used as a suture anchor?

Purpose: To determine the biomechanical strength properties of suture capsulolabral plication to an intact labrum versus glenoid bone anchor fixation.

Methods: Fourteen paired fresh frozen shoulders with intact glenoid labrum and mean age of 43.3 +/- 11.

Intra-articular partial-thickness rotator cuff tears: analysis of injured and repaired strain behavior.

Background: There are few biomechanical studies regarding partial-thickness rotator cuff tears and subsequent repair.

Hypothesis: Partial-thickness intra-articular supraspinatus tendon tears increase articular-sided tendon strain as they increase in size. Repair of these tears will return strain to the intact state.
