Growth of Cartilage and Bone Tissue01:27

Growth of Cartilage and Bone Tissue

4.0K
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

Knee Joint01:23

Knee Joint

3.1K
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...

Ultrasonography01:17

Ultrasonography

7.3K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Area of Science:

  • Orthopedics
  • Radiology
  • Biomedical Engineering

Background:

  • Osteoarthritis (OA) is the most prevalent joint disease in the U.S., with rising incidence linked to an aging population and obesity.
  • Cartilage degradation is a primary characteristic of OA, and current treatments have limited success in disease modification.
  • Magnetic Resonance Imaging (MRI) offers noninvasive visualization of joint structures, crucial for understanding OA progression.

Purpose of the Study:

  • To review current clinical MRI techniques for cartilage assessment in Osteoarthritis.
  • To discuss semiquantitative and quantitative MRI methods for evaluating cartilage health.
  • To highlight the role of advanced MRI in developing future joint preservation strategies for OA.

Main Methods:

  • This narrative review synthesizes information on clinical MR image acquisition and cartilage assessment.
  • It covers established semiquantitative cartilage scoring methods used in OA research.
  • It explores quantitative MRI techniques for detecting biochemical changes in cartilage.

Main Results:

  • MRI provides unparalleled noninvasive assessment of all joint structures.
  • Advancements in MRI-based cartilage imaging are crucial for future OA treatment development.
  • Quantitative MRI can detect biochemical cartilage changes before morphological alterations are visible.

Conclusions:

  • MRI is indispensable for the noninvasive assessment of joint structures in Osteoarthritis.
  • Advanced MRI techniques, particularly quantitative methods, show promise for early detection of cartilage biochemical changes.
  • These imaging advancements are vital for developing effective joint preservation strategies for Osteoarthritis.
