Viscoelasticity measurement of ex vivo bovine cartilage using Lamb wave method.

This study validates the use of the LWM for measuring the viscoelasticity of ex vivo cartilage and provides a critical step toward the ultimate goal of measuring the viscoelasticity of cartilage in vivo. PMID: 30484437 [PubMed - in process]

Conclusion: It appears that the knee OA pain and disability can be decreased after a dual-frequency LLLT applied to acupoints (SP9, SP10, and EX-LE2). The clinical efficacy of LLLT is highly related to the therapeutic settings of the laser apparatus; hence, more clinical trials with diffident parameter settings are needed to be further clarified.

CONCLUSION: According to our subclinical electrophysiological findings, surgeons that use the posterolateral approach in THA procedures must be conscious of the sciatic nerve's vulnerability to reduce possible clinical complications. PMID: 33031693 [PubMed - as supplied by publisher]

Study Design. Retrospective observational study from the Nagano Cohort Study. Objective. Clarify the association between spinal osteoarthritis and loss of stature in postmenopausal women. Summary of Background Data. Loss of stature with aging is known to deteriorate health-related quality of life and has been implicated with increased mortality. Although the association of vertebral fracture with height loss has been well documented, the relationship between stature loss and spinal osteoarthritis remains unclear. Methods. We retrospectively investigated Japanese postmenopausal women recruited from the Nagano Coh...

Authors: Nunes RM, Girão VCC, Castro RR, Cunha PLR, Feitosa JPA, Pinto ACMD, Castro Rocha FA Abstract PURPOSE: To determine alterations of chondroitin sulfate (CS) that reflect cartilage damage in an experimental osteoarthritis (OA) model as well as in human OA samples. MATERIALS AND METHODS: Rats were subjected to anterior cruciate ligament transection (ACLT; OA) or a sham procedure and sacrificed 14, 28, or 70 days after ACLT for histopathology and analysis of extracted CS. Cartilage samples from 14 patients undergoing hip or shoulder arthroplasty secondary to OA or fracture (control) were subject...

The temporomandibular joint (TMJ) is the synovial joint of craniofacial complex and is critical for dental occlusion, mastication, and speech. TMJ trauma and diseases, such as osteoarthritis, are debilitating and compromise quality of life. Current TMJ treatments are two-fold, involving either palliative care or invasive total joint replacement surgeries. There are no minimally invasive, regenerative TMJ therapies. We have identified TMJ-specific fibrocartilage stem cells that self-organize and regenerate cartilage, fat and vascularized bone. Here we define heterogeneous populations of TMJ fibrocartilage stem cells and the...

Comorbidity and health care utilisation in persons with Sjögren's syndrome: a claims data analysis. Clin Exp Rheumatol. 2020 Sep 18; Authors: Albrecht K, Dörner T, Redeker I, Karberg K, Marschall U, Zink A, Callhoff J Abstract OBJECTIVES: To capture comorbidity and medication of persons with Sjögren's syndrome (SS) in a population-based cohort in comparison to matched controls. METHODS: Individuals with an outpatient diagnosis of M35.0 (ICD-10) in ≥2 quarters of a year or an inpatient diagnosis of M35.0 were identified in a German statutory health insurance fund covering 7.2 milli...

Authors: Lee C, Brodke D, Perdue PW, Patel T Abstract The talus is unique in having a tenuous vascular supply and 57% of its surface covered by articular cartilage. Fractures of the head, neck, or body regions have the potential to compromise nearby joints and impair vascular inflow, necessitating surgical treatment with stable internal fixation in many cases. The widely preferred approach for many talar neck and body fractures is a dual anterior incision technique to achieve an anatomic reduction, with the addition of a medial malleolar osteotomy as needed to visualize the posterior talar body. Percutaneous screw ...

Introduction: Sneathia sanguinegens(S sanguinegens) is a gram-negative rod-shaped bacterium mostly reported to cause a perinatal infection, and there are no reports of S sanguinegens in prosthetic joint infection (PJI). The purpose of this report is to describe a very rare case of PJI after total hip arthroplasty (THA) caused by S sanguinegens. Patient concerns: A 79-year-old woman presented with right coxalgia, inability to walk, and a fever of 39°C. She had undergone THA 28 years earlier for osteoarthritis of the hip. Diagnoses: The diagnosis was acute late-onset PJI, because blood tests revealed marked infla...
