The effects of soft tissue injury to the glenohumeral capsule on shoulder mechanics have been the focus of our shoulder biomechanics research program. This has included biomechanical, mathematical modeling and histomorphological studies. Biomechanically, experiments have investigated the kinematics of the glenohumeral joint with Bankart lesions and graded Bankart repairs. Also, a device has been devised and tested to quantify glenohumeral joint laxity in human subjects, and will be used to define differences among normal, injured, and repaired shoulders. Using mathematical modeling techniques, the tensions and strain within the glenohumeral ligaments and the contact forces and stresses between the humeral head and glenoid surfaces were predicted with an analytical model of the glenohumeral joint.
