Neurologic deficit after reverse total shoulder arthroplasty: correlation with distalization.

Background: Neurologic problems after reverse total shoulder arthroplasty (RTSA) have been reported, but there are a lack of studies regarding which nerve(s) are damaged and the outcomes for the patients who had neurologic complications after RTSA. The purpose of this study was to assess the prevalence and outcomes of neurologic deficit after RTSA and to evaluate the correlation between nonanatomic rearrangement of the shoulder joint and neurologic complications after RTSA. We hypothesized that the neurologic deficit was associated with excessive distalization or lateralization of the humerus after RTSA.

Selective pie-crust release of superficial medial collateral ligament in medial open-wedge high tibial osteotomy.

Various techniques to release the superficial MCL (sMCL) during medial open-wedge high tibial osteotomy (MOWHTO) has been introduced. However, there have been debates regarding the extent of sMCL release in MOWHTO. The authors present a pie-crust technique that involves selective and gradual release of sMCL from inside using a small, round-tip blade after opening the gap.

Safe time frame of staged bilateral arthroscopic rotator cuff repair.

Methods: We analyzed 166 shoulders that underwent staged bilateral ARCR.

Intra-Articular Injection of Autologous Adipose Tissue-Derived Mesenchymal Stem Cells for the Treatment of Knee Osteoarthritis: A Phase IIb, Randomized, Placebo-Controlled Clinical Trial.

Mesenchymal stem cells (MSCs) have been the focus of an emerging treatment for osteoarthritis. However, few studies reported about outcomes of an intra-articular injection of autologous adipose-derived mesenchymal stem cells (AD-MSCs). This study aimed to assess the efficacy and safety of a single intra-articular injection of AD-MSCs for patients with knee osteoarthritis.

When Do Patients Return to Previous Daily Activity After Arthroscopic Rotator Cuff Repair?

Background: One potential advantage of arthroscopic shoulder surgery over open approaches is accelerated recovery; however, the functional recovery period of daily activities for specific movements after arthroscopic rotator cuff repair has not yet been reported, to our knowledge.

Questions/purposes: (1) After arthroscopic rotator cuff repair, when are patients able to perform low-level and high-level front-of-body motion, low-level and high-level behind-the-back motion, strength-related activities, and sports/leisure activities? (2) How do tear size, arm dominance, and retear affect performance of these activities? (3) When does the UCLA score cross above 80% in each UCLA score component (28 points)?

Methods: A 2-year prospective study of 135 patients who underwent arthroscopic rotator cuff repair was performed (45 in small-sized, 45 in medium-sized, and 45 in large-to-massive-sized groups). The mean age was 60 years.

Does the pre-operative status of the anterior cruciate ligament affect the outcomes following medial open-wedge high tibial osteotomy?

Background: This study aimed to assess the morphological degeneration of the anterior cruciate ligament (ACL) through magnetic resonance imaging (MRI) and arthroscopy.

Methods: From May 2008 to November 2015, 164 knees underwent MOWHTO using a locked plate system for the treatment of knee osteoarthritis. LHFs were recognized by radiographs during or after the high tibial osteotomy and were not additionally treated.

Tranexamic acid is effective for blood management in open-wedge high tibial osteotomy.

Introduction: There has been paucity in literature regarding the blood-sparing effect of TXA after high tibial osteotomy (HTO). The purpose of this study is to determine the efficacy of tranexamic acid (TXA) with regard to its blood-sparing effects in open-wedge HTO, and to assess thromboembolic complications in patients undergoing open-wedge HTO with or without the use of TXA.

Hypothesis: The intravenous TXA would reduce postoperative blood loss and transfusion requirements without increasing thromboembolic complications in open-wedge HTO.

Unconventional pore and defect generation in molybdenum disulfide: application in high-rate lithium-ion batteries and the hydrogen evolution reaction.

A 2H-MoS2 (H=hexagonal) ultrathin nanomesh with high defect generation and large porosity is demonstrated to improving electrochemical performance, including in lithium-ion batteries (LIBs) and the hydrogen evolution reaction (HER), with the aid of a 3D reduced graphene oxide (RGO) scaffold as fast electron and ion channels. The 3D defect-rich MoS2 nanomesh/RGO foam (Dr-MoS2 Nm/RGO) can be easily obtained through a one-pot cobalt acetate/graphene oxide (GO) co-assisted hydrothermal reaction, in which GO, cobalt and acetate ions are co-morphology-controlling agents and defect inducers. As an anode material for LIBs, Dr-MoS2 Nm/RGO has only a 9% capacity decay at a 10 C discharge rate versus 0.

Controlled thermal sintering of a metal-metal oxide-carbon ternary composite with a multi-scale hollow nanostructure for use as an anode material in Li-ion batteries.

We report a synthetic scheme for preparing a SnO2-Sn-carbon triad inverse opal porous material using the controlled sintering of Sn precursor-infiltrated polystyrene (PS) nanobead films. Because the uniform PS nanobead film, which can be converted into carbon via a sintering step, uptakes the precursor solution, the carbon can be uniformly distributed throughout the Sn-based anode material. Moreover, the partial carbonization of the PS nanobeads under a controlled Ar/oxygen environment not only produces a composite material with an inverse opal-like porous nanostructure but also converts the Sn precursor/PS into a SnO2-Sn-C triad electrode.

Meniscus allograft transplantation: a comparison of medial and lateral procedures.

Background: Because of the anatomic and biomechanical differences between the lateral and medial menisci, it is believed that the indications, combined injuries, techniques, and outcomes of the 2 meniscus allograft transplantation (MAT) procedures may be different.

Hypothesis: Medial meniscus transplantation (medial group) usually combines concomitant surgeries, such as anterior cruciate ligament (ACL) reconstruction, so the medial group will have worse clinical results than the lateral group (lateral meniscus transplantation).

Study Design: Cohort study; Level of evidence, 3.

Polymer-free Vertical Transfer of Silicon Nanowires and their Application to Energy Storage.

Silicon nanowires (SiNWs) for use as lithium-ion battery (LIB) anode materials have been studied for their one-dimensional (1D) properties and ability to accommodate large volume changes and avoid rapid capacity fading during cycling. Although the vertical transfer of SiNWs from their original substrate onto a conducting electrode is very important, to date, there has been no report of a direct integration method without polymer binders. Here, we propose for the first time a vertical transfer method for SiNWs grown on a Si substrate directly to the current-collecting electrode without using a polymer adhesive for the use as a binder-free LIB anode.

Graphene/acid coassisted synthesis of ultrathin MoS2 nanosheets with outstanding rate capability for a lithium battery anode.

Morphology-controlled MoS2 nanosheets were successfully synthesized with the aid of graphene/acid coexistence by a one-pot hydrothermal method. The ultrathin MoS2 nanosheets were self-assembled into a cockscomb-like structure with an exposed (100) facet on graphene sheets, which is in strong contrast to large aggregate MoS2 plates grown freely on graphene sheets without acetic acid. The ultrathin MoS2 nanosheets displayed excellent rate performance for Li storage (709 mAh·g(-1) capacity at 8320 mA·g(-1) discharging rate) and superior charge/discharge cyclability.

One-pot synthesis of carbon-coated SnO2 nano-composite using hydrothermal method for lithium ion battery application.

Ultraviolet photodepletion spectroscopy of dibenzo-18-crown-6-ether complexes with alkaline Earth metal divalent cations.

Ultraviolet photodepletion spectra of dibenzo-18-crown-6-ether complexes with alkaline earth metal divalent cations (A(2+)-DB18C6, A = Ba, Sr, Ca, and Mg) were obtained in the gas phase using electrospray ionization quadrupole ion-trap reflectron time-of-flight mass spectrometry. Each spectrum exhibits the lowest energy absorption band in the wavenumber region of 35 400-37 800 cm(-1), which is tentatively assigned as the origin of the S(0)-S(1) transition of A(2+)-DB18C6. This origin band shows a red shift as the size of the metal dication increases from Mg(2+) to Ba(2+).

Ultraviolet photodepletion spectroscopy of dibenzo-18-crown-6-ether complexes with alkali metal cations.

Ultraviolet photodepletion spectra of dibenzo-18-crown-6-ether complexes with alkali metal cations (M(+)-DB18C6, M = Cs, Rb, K, Na, and Li) were obtained in the gas phase using electrospray ionization quadrupole ion-trap reflectron time-of-flight mass spectrometry. The spectra exhibited a few distinct absorption bands in the wavenumber region of 35 450-37 800 cm(-1). The lowest-energy band was tentatively assigned to be the origin of the S(0)-S(1) transition, and the second band to a vibronic transition arising from the "benzene breathing" mode in conjunction with symmetric or asymmetric stretching vibration of the bonds between the metal cation and the oxygen atoms in DB18C6.
