Medial Meniscotibial Ligament Deficiency Increases Medial Meniscus Extrusion and Posterior Root Forces.

Background: There is growing evidence that medial meniscotibial ligament (MTL) deficiency and medial meniscus extrusion may precede the development of some medial meniscus posterior root (MMPR) tears. However, no study has investigated the biomechanical consequences of MTL deficiency on the MMPR.

Hypothesis: (1) MTL deficiency leads to increased medial meniscus extrusion, (2) increased medial meniscus extrusion is correlated with increased compression and shear forces at the MMPR, and (3) MTL repair restores medial meniscus extrusion and MMPR forces to native levels.

Minimum 10-Year Clinical and Functional Outcomes, and Return to Sport After Sternoclavicular Joint Reconstruction for Sternoclavicular Joint Instability.

Background: Sternoclavicular joint (SCJ) instability can lead to pain, reduced function, and an inability to perform sports and activities of daily living. Reconstruction of the SCJ using hamstring autograft in a figure-of-8 configuration has demonstrated good outcomes at short- and midterm follow-ups, but there is a paucity of literature on long-term outcomes.

Purpose: To evaluate the long-term clinical and functional outcomes after SCJ reconstruction, with a focus on return to sport, instability recurrence, and revision surgery.

The Use of the Anterior Labral Circumferential Onlay Technique to Reconstruct the Anterior Labrum and Biomechanically Restore Glenohumeral Joint Stability.

Background: A labral injury contributes to glenohumeral instability. The Anterior Labral Circumferential Onlay Technique (ALCOT) reconstructs the labrum using the long head of the biceps tendon.

Hypothesis: The ALCOT would restore glenohumeral joint stability in a cadaveric model without glenoid bone loss (1) comparable to the native state and (2) comparable to the Latarjet procedure.

Unicortical button fixation provides higher strength compared with transosseous repair for subscapularis tendon in total shoulder arthroplasty.

Background: Subscapularis tendon (SSc) dysfunction after total shoulder arthroplasty (TSA) results in poor functional outcomes. There have been numerous SSc repair constructs tested biomechanically and clinically; however, none has been demonstrated as superior. Newer techniques and implants have emerged but have not been fully tested.
