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.

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.

The effect of number of knots per throw, knot technique, and suture type on strength properties of suspensory fixation button surgical procedures.

Background: Previous studies of the cortical suspensory button (CSB) implant have analyzed fixation strength as a function of suture type and surgical technique, but knot configuration remains an area of interest. This study investigates 4-strand knot configurations in CSB suspensory fixation, specifically comparing the use of 2 separate knots with a single knot. We hypothesize that using 2 knots on the distal side of the CSB with #2 suture will yield the strongest and stiffest suspensory fixation.
