[High tibial osteotomy combined with lateral retinacular release for the treatment of knee varus osteoarthritis with lateral patellar compression syndrome].

Objective: To investigate the clinical effect of high tibial osteotomy combined with arthroscopic lateral retinacular release in the treatment of knee varus osteoarthritis.

Methods: From October 2017 to April 2019, a retrospective analysis was performed on 43 patients with knee varus osteoarthritis and lateral patellar compression syndrome treated by high tibial osteotomy combined with arthroscopic lateral retinacular release. There were 15 males and 28 females, aged 53 to 72(62.

[Evaluation of cartilage regeneration by arthroscopy after high tibial osteotomy].

Objective: To evaluate the cartilage regeneration in the knee joint by arthroscopy after high tibial osteotomy.

Methods: Eleven patients were included in the study who were treated with high tibial osteotomy and underwent microscopy when the internal fixation was unloaded from September 2017 to September 2019. Among them, there were 2 males and 9 females, aged from 55 to 64 years old.

[High tibial osteotomy combined with arthroscopy for elderly patients with knee osteoarthritis of medial compartment].

Objective: To observe early clinical effect of high tibial osteotomy combined with arthroscopy for elderly patients with knee osteoarthritis of medial compartment.

Methods: Sixty-one elderly patients with medial compartment knee osteoarthritis were treated with high tibial osteotomy combined with arthroscopy from August 2017 to October 2018. Among them, including 17 males and 44 females, aged from 60 to 83 years old with an average of (67.

[Clinical applications of the neurocutaneous axial flap pedicled with perforating vessels].

Objective: To report the operative technique and clinical results of the neurocutaneous vascular axial flap with perforating vessels as its pedicle.

Methods: An axial skin flap was designed along the axis of small paraneural vessels that was close to a concomitant cutaneous nerve. The cutaneous perforating branches of major arteries were used as the pedicle, which provided a rotation arc for the flap to cover the defects in the distal site of extremities.

Magic doping fractions for high-temperature superconductors.

We report hole-doping dependence of the in-plane resistivity rho(ab) in a cuprate superconductor La(2-x)Sr(x)CuO4, carefully examined using a series of high-quality single crystals. Our detailed measurements find a tendency towards charge ordering at particular rational hole-doping fractions of 1/16, 3/32, 1/8, and 3/16. This observation appears to suggest a specific form of charge order and is most consistent with the recent theoretical prediction of the checkerboard-type ordering of the Cooper pairs at rational doping fractions x = (2m+1)/2n, with integers m and n.

Pair density wave in the pseudogap state of high temperature superconductors.

Recent scanning tunneling microscopy experiments of Bi(2)Sr(2)CaCu(2)O(8+delta) have shown evidence of real-space organization of electronic states at low energies in the pseudogap state [Science 303, 1995 (2004)]]. We argue based on symmetry considerations as well as model calculations that the experimentally observed modulations are due to a density wave of d-wave Cooper pairs without global phase coherence. We show that scanning tunneling microscopy measurements can distinguish a pair density wave from more typical electronic modulations such as those due to charge density wave ordering or scattering from an on site periodic potential.

Quantitative test of SO(5) symmetry in the vortex state of Nd(1.85)Ce(0.15)CuO4.

By numerically solving models with competing superconducting and antiferromagnetic orders, we study the magnetic field dependence of the antiferromagnetic moment in both the weak and strong field regimes. Through a comparison with the neutron scattering results of Kang et al. and Matsuura et al.

Antiferromagnetism and hole pair checkerboard in the vortex state of high T(c) superconductors.

We propose a microscopic state for the vortex phase of BSCO superconductors. Around the vortex core or above H(c2), the d wave hole pairs form a checkerboard localized in the antiferromagnetic background. We discuss this theory in connection with recent STM experiments.
