Background: Despite clinical evidence of risks in knee arthrofibrosis and graft impingement with larger grafts, the optimal size for quadriceps tendon (QT) autografts anterior cruciate ligament reconstruction (ACLR) has not been established. Purpose/Hypothesis: This study aimed to evaluate mechanical properties full-thickness 6-mm 8-mm wide QT grafts compared 10-mm patellar (PT) grafts. The hypothesis was that both 6- would exhibit similar or superior ultimate tensile strength PT graft....
Torn and damaged menisci resulting from trauma are very common knee injuries, which can cause pain mobility limitations lead to osteoarthritis. Meniscal injuries require surgery repair the tissue damage restore mobility. Here we describe biomechanical testing of a 3D-printed meniscus illustrate methods determine if it has strength durability effectively meniscal tears biomechanics. This work was designed demonstrate steps needed test novel devices prior moving toward animal testing. The...
The use of fuel cells as an alternative to traditional small scale power producing devices such internal combustion engines or disposable batteries has continued gain widespread acceptance. Flow maldistribution within in a stack continues be issue cell design and can adversely affect performance longevity. Current research this field focused on effects inlet configurations (plug flow versus circular inlet, for example) the rectangular manifold resulting distribution into individual stack. In...
PURPOSEThe purpose of this study was to evaluate the maximal load failure, cyclic displacement, stiffness, and modes failure onlay subpectoral biceps tenodesis with an intramedullary unicortical metal button (MB) versus inlay, all-suture Caspari-Weber (CW) technique.METHODSSixteen matched paired human cadaveric proximal humeri were randomly allocated for BT either CW or MB using a high-strength suture (n = 16; 8 male, female, mean age 82.5 years, range 62-99 years). Specimens tested on...
BackgroundLimitations to using the knee as donor cartilage include thickness mismatch and site morbidity. Utilizing radial head autograft for capitellar lesions may allow local graft harvest without distant The purpose of this study is demonstrate feasibility performing osteochondral transfer from non-articular cartilaginous rim capitellum. Additionally, we sought determine load failure after harvest.MethodsSixteen matched cadaveric elbows were utilized. A Kaplan approach was performed in...
Achievement of flow uniformity among cells a fuel cell stack continues to be an issue in design and can affect performance longevity. While many studies have sought examine the effects manifold geometries on pressure drops current density, few provided detailed mapping flowfield or examined effect reactant supply pipe bends this flow, as these introduce asymmetries within downstream bend. A simplified scaled up model proton exchange membrane (PEM) was fitted with different inlet...
The purpose of this project was to study experimentally and numerically the effects changing geometrical parameters on water single-phase pressure drop across arrays micro-scale pin-fin heat sinks. An experimental performed a cylindrical sink at various flow rates temperatures. Computational analysis also array certain geometric compare these results with previous numerical results. for method were not as expected due malfunctioning equipment had be compared existing data in order validate model.
Cartilage loses, recovers, and maintains its thickness, hydration, biomechanical functions by adjusting relative rates of load-induced fluid loss competitive recovery under varying joint-use conditions. While the mechanics implications have been studied extensively, those not. This study isolates, quantifies, compares cartilage from three known modes: (1) passive swelling – within a nominally unloaded contact; (2) free at an exposed surface; (3) tribological rehydration loaded contact area...
