Knee Joint01:23

Knee Joint

3.6K
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...

Ankle Joint01:10

Ankle Joint

3.4K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Bone Disorders01:29

Bone Disorders

6.0K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

4.6K
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...

Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

568
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Introduction to Joints00:58

Introduction to Joints

5.6K
The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Joints are the location where bones come together. Many joints allow for movement between the bones. At these joints, the articulating surfaces of the adjacent bones can move smoothly against each other. However, the bones of other joints may be joined by connective tissue or cartilage. These joints are designed for stability and provide little or no...

    Summary
    This summary is machine-generated.

    Running and impact sports do not cause osteoarthritis in healthy joints but can worsen existing conditions. Individuals with joint issues should choose low-impact exercises like cycling and strength training.

    Area of Science:

    • Orthopedics
    • Sports Medicine
    • Rheumatology

    Background:

    • Osteoarthritis (OA) is a degenerative joint disease.
    • The role of high-impact physical activity in OA development is debated.
    • Understanding exercise effects on joint health is crucial for prevention and management.

    Purpose of the Study:

    • To investigate whether running and impact-loading sports contribute to osteoarthritis development.
    • To determine the effects of such activities on healthy versus pre-damaged joints.
    • To provide exercise recommendations for individuals with and without pre-existing joint conditions.

    Main Methods:

    • Review of current literature on osteoarthritis and exercise.
    • Analysis of the biomechanical effects of impact-loading activities on joints.
    • Clinical recommendations based on existing evidence.

    Main Results:

    • Impact-loading activities do not cause osteoarthritis in healthy joints.
    • These activities can accelerate osteoarthritis progression in joints with pre-existing damage.
    • Non-impact exercises are suitable for individuals with OA.

    Conclusions:

    • Individuals with normal joints can engage in running and impact sports without increasing OA risk.
    • Screening for pre-existing joint disease is essential before initiating exercise programs.
    • Stationary cycling and weight training are recommended for joint support and OA management.
