Background: Rotating-hinge knee (RHK) implants are an option for arthroplasty in cases of instability or severe bone loss. However, the revision rate can be increased compared to unconstrained which mandate improvements implant design. This study investigates a novel RHK design total (TKA). Methods: Retrospective analysis single TKA (GenuX MK, Implantcast) implanted between 2015 and 2019 includ...

BACKGROUND The clinical and radiological outcomes of revision total knee arthroplasty with a cemented posterior stabilized (PS), condylar constrained knee (CCK) or a fully constrained rotating hinge knee (RHK) prosthesis were evaluated. METHODS This study reviewed the clinical and radiological results of 36 revision total knee arthroplasties with a cemented PS, CCK, and RHK prosthesis in 8, 2...

Background The prognosis of complex primary total knee arthroplasty (TKA) with severe deformity and ligament deficiency is not clear. There a paucity evidence in the current literature on treatment outcomes rotating hinge implants TKA. aim this study was to determine mid-term clinical, radiographic, health-related quality life (HRQoL) patients who had undergone TKA using single hinged replaceme...

Variability of 226 AGNs in the near-infrared J , H , and K ′ bands is analyzed and discussed. An ensemble average for measured variabilities was obtained for various samples of the AGNs divided by absolute B-magnitude MB, redshift z, and radio strength. All the samples in the J , H , and K ′ bands are found to give significant ensemble variability, but no significant wavelength dependence is fo...

We present the results of a study of the stellar activity in the solar neighborhood using complete kinematics (galactocentric velocities U,V,W) and the chromospheric activity index log RHK. We analyzed the average activity level near the centers of known moving groups using a sample of 2529 stars and found that the stars near these associations tend to be more active than field stars. This supp...

Keratins are highly attractive for medical applications due to their inherent self-assemblies characteristics and biocompatibility. However, nearly all researches have focused on the properties of hybrid hydrogels which was prepared from human hair keratin with other materials, preparation methods pure rarely studied. Thus, we extracted keratins rabbit hair, a low concentration high purity RHK ...

The Doppler measurements of stars are diluted and distorted by stellar activity noise. Different choices of noise models and statistical methods have led to much controversy in the confirmation of exoplanet candidates obtained through analysing radial velocity data. To quantify the limitation of various models and methods, we compare different noise models and signal detection criteria for vari...
