Intra-articular Neoplasms and Masslike Lesions of the Knee: Emphasis on MR Imaging.

Magn Reson Imaging Clin N Am 2022 May 13;30(2):339-350. Epub 2022 Apr 13.

Department of Radiology, UCSD Health System, University of California, HCOP MRI, 408 Dickinson Street, San Diego, CA 92103-8226, USA.

Intra-articular masses affecting the knee joint are uncommon lesions that encompass a range of neoplastic and nonneoplastic disorders. A joint mass limited to a single articulation is most commonly related to neoplastic or focal proliferative disease, whereas masses affecting multiple articulations are typically caused by underlying inflammatory arthritides, metabolic abnormalities, or systemic deposition disorders. This article focuses on those masses that present in a monoarticular fashion, emphasizing the lesions that most commonly affect the knee joint. Read More

This disease usually involves larger joints (knee, hip, elbow, and shoulder), but it has also rarely been reported in the hand. Patients with this disease complain of pain, swelling, nodules, and decreased range of motion of the affected joint. Read More

Synovial macrophages in cartilage destruction and regeneration-lessons learnt from osteoarthritis and synovial chondromatosis.

Biomed Mater 2021 12 9;17(1). Epub 2021 Dec 9.

School of Mechanical, Medical and Process Engineering, Centre for Biomedical Technologies, Queensland University of Technology (QUT), Brisbane, QLD 4000, Australia.

Inflammation is a critical process in disease pathogenesis and the restoration of tissue structure and function, for example, in joints such as the knee and temporomandibular. Within the innate immunity process, the body's first defense response in joints when physical and chemical barriers are breached is the synovial macrophages, the main innate immune effector cells, which are responsible for triggering the initial inflammatory reaction. Macrophage is broadly divided into three phenotypes of resting M0, pro-inflammatory M1-like (referred to below as M1), and anti-inflammatory M2-like (referred to below as M2). Read More
