Fixation strength in arthroscopic labral repair of the hip: A head-to-head comparison of the biomechanical performance of a biocompatible vs. all-suture anchor in the setting of acetabuloplasty Open
Much is known about the biomechanical performance of various types of suture anchors commonly used for labral fixation in the shoulder; however, similar studies in the hip are less common. We sought to compare all-suture and polyether ethe…

Endoscopic Gluteus Medius Repair Replicates Open, Knotless Repair With Similar Cyclic Loading Properties: A Cadaveric Study Open
Gluteus medius tendinopathy is an increasingly common recognized etiology of lateral hip pain. When tears occur, debate exists over whether open or endoscopic repair procedures are optimal. Double-row endoscopic gluteus medius repair with …

In-line Pullout Strength of 2 Acetabular Fixation Methods for Ligamentum Teres Reconstruction of the Hip: A Cadaveric Study Open
Background: Ligamentum teres (LT) reconstruction is an appropriate alternative in select cases of LT full-thickness tears, resulting in hip micro- or macroinstability. Graft fixation at the acetabular fossa is critical to achieving the bes…

Collagen Dysregulation in the Dermis of the Sagg/+ Mouse: A Loose Skin Model Open
The Sagg/+ mouse is an ethylnitrosourea-derived mutant with a dermal phenotype similar to some of the subtypes of Ehlers-Danlos syndrome (EDS) and cutis laxa. The dermis of the Sagg/+ mouse has less dense and more disorganized collagen fib…

View article: Biomechanical Comparison of 3 Syndesmosis Repair Techniques With Suture Button Implants
Biomechanical Comparison of 3 Syndesmosis Repair Techniques With Suture Button Implants Open
Background: Suture button fixation of syndesmotic injury is growing in popularity, as it has been shown to provide adequate stability in a more cost-effective manner than screw fixation while allowing more physiologic distal tibiofibular j…

Endoscopic Proximal Hamstring Repair: Portal Site Anatomy - A Cadaveric Study Open
Objectives: Hamstring injuries commonly cause pain, weakness and functional limitations. While most hamstring injuries involve the musculotendinous junction or muscle belly, proximal hamstring tendon avulsions are a subset of hamstring inj…
View article: Biomechanical Comparison of Open and Endoscopic Proximal Hamstring Repair Techniques
Biomechanical Comparison of Open and Endoscopic Proximal Hamstring Repair Techniques Open
Objectives: Proximal hamstring tendon avulsions are a rare subset of hamstring injuries, and surgical fixation has become standard, given superior outcomes compared to nonoperative treatment. Open surgical techniques employ a large incisio…
