Knee Joint01:23

Knee Joint

1.6K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Bones of the Lower Limb: Femur and Patella

2.3K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

2.9K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

331
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Connective Tissue Cell Types01:22

Connective Tissue Cell Types

3.2K
Connective tissue develops from the mesoderm of a developing embryo and consists of cells, fibers, and ground substance: a gel-like material containing large complexes of carbohydrates and proteins. Connective tissue was first identified as a separate tissue family in the 18th century, and Johannes Peter Muller coined the term connective tissue.
Fat cells (adipocytes), smooth muscle cells (myoblasts), and bone cells (osteoblasts) are some connective tissue cell types. Some immune system cells...

Area of Science:

  • Nutrition Science
  • Rheumatology
  • Public Health

Background:

  • Knee osteoarthritis (OA) is a prevalent degenerative joint disease causing significant disability, especially in aging populations.
  • While conventional treatments exist, dietary interventions show promise for managing OA symptoms and progression.
  • Many popular nutritional beliefs regarding knee OA lack scientific support and can be misleading.

Purpose of the Study:

  • To review the impact of nutrition on knee osteoarthritis (OA).
  • To debunk myths surrounding knee OA nutrition and highlight evidence-based dietary strategies.
  • To provide clinicians with actionable nutritional modifications for knee OA management.

Main Methods:

  • Comprehensive literature review focusing on the role of key nutrients in knee OA.
  • Analysis of scientific evidence regarding the effects of carbohydrates, fats, proteins, antioxidants, and micronutrients.
  • Evaluation of the efficacy of dietary patterns like the Mediterranean diet and supplements.

    • Main Results:

    • High-carbohydrate and high-fat diets (refined sugars, saturated fats) worsen inflammation and cartilage degradation in knee OA.
    • Diets rich in omega-3 fatty acids, polyphenols, and fiber demonstrate anti-inflammatory and chondroprotective effects.
    • The Mediterranean diet shows potential in preventing OA and related comorbidities; supplement efficacy (glucosamine, chondroitin, vitamin D) remains questionable.

    Conclusions:

    • Nutrition plays a critical role in knee OA management, with specific nutrients offering therapeutic benefits.
    • Evidence-based dietary strategies, emphasizing whole foods and specific nutrients, are crucial for knee OA treatment.
    • Further controlled studies are needed to establish definitive nutritional guidelines for knee OA, promoting personalized and sustainable approaches.
