Radiology Case Reports, 2017 A case of a right knee intra-articular osteolipoma in a 64-year-old man is reported. The patient presented for evaluation of a 1-year history of nontraumatic, mechanically-exacerbated, medial-sided right knee pain. Radiographs demonstrated a partially calcified 3.0 cm mass anterior to the distal medial femur at the suprapatellar fossa.

Models for the Origin of the Knee in the Cosmic-Ray Spectrum [PDF]
, 2000 A sudden steepening of the cosmic-ray energy spectrum (the knee) is observed at an energy of about 3 PeV (1 PeV = $10^{15}$ eV). The experimental study of the PeV cosmic rays has intensified greatly during the last 3 years. The recent results on extensive air showers allow us to conclude that: a) the knee has an astrophysical origin; b) the `sharpness'

Knee Cartilage Defect Assessment by Graph Representation and Surface Convolution [PDF]
arXiv, 2022 Knee osteoarthritis (OA) is the most common osteoarthritis and a leading cause of disability. Cartilage defects are regarded as major manifestations of knee OA, which are visible by magnetic resonance imaging (MRI). Thus early detection and assessment for knee cartilage defects are important for protecting patients from knee OA.

Knee osteoarthritis has doubled in prevalence since the mid-20th century
Proceedings of the National Academy of Sciences of the United States of America, 2017 Significance Knee osteoarthritis is a highly prevalent, disabling joint disease with causes that remain poorly understood but are commonly attributed to aging and obesity.

Journal of the American Medical Association (JAMA), 2017 Importance Synovitis is common and is associated with progression of structural characteristics of knee osteoarthritis. Intra-articular corticosteroids could reduce cartilage damage associated with synovitis but might have adverse effects on cartilage ...

Cosmic ray composition and energy spectrum above 1 TeV: direct and EAS measurements [PDF]
Nucl.Phys.Proc.Suppl. 97 (2001) 35-47, 2000 The most recent experimental results on the cosmic ray composition and energy spectrum above 1 TeV are reviewed and discussed. All data agree on the presence of the so-called ``knee'' at an energy E(knee) = 3-4 PeV; the knee is seen in all the components of the Extensive Air Showers.

BMC Musculoskeletal Disorders, 2018 Background Anterior cruciate ligament (ACL) reconstruction is today’s surgical gold standard for ACL rupture. Although it provides satisfactory results, not all patients return to their previous activity level and moreover, early posttraumatic ...

A Search for Fine Structure of the Knee in EAS Size Spectra [PDF]
Astropart.Phys. 17 (2002) 13-22, 2001 28 size spectra of extensive air showers from 7 different experiments are analysed consistently. They are fitted by adjusting either 4 or 5 parameters: knee position, power law exponents above and below the knee, overall intensity and, in addition, a parameter describing the smoothness of the bend.
