Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

133
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...

Knee Joint01:23

Knee Joint

2.7K
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

4.2K
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...

Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

315
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Summary

Knee medial arthrosis stems from muscle imbalance, worsened by aging. Early intervention with muscle correction and partial meniscectomy can improve outcomes, avoiding extensive knee surgeries.

Area of Science:

  • Orthopedics
  • Biomechanics
  • Geriatric Medicine

Background:

  • Medial knee arthrosis is an evolutionary condition driven by progressive muscle imbalance.
  • Aging exacerbates this imbalance through muscle strength loss, leading to pathological postures and joint pressure.
  • This imbalance contributes to meniscal and cartilage injuries, hallmarks of knee arthrosis progression.

Purpose of the Study:

  • To elucidate the role of muscle imbalance in the pathogenesis of medial knee arthrosis.
  • To highlight the importance of early diagnosis for conservative treatment success.
  • To discuss the efficacy of muscle reeducation and meniscectomy in early-stage disease.

Main Methods:

  • Observational analysis of biomechanical factors in knee arthrosis.
  • Review of clinical progression and treatment outcomes based on disease stage.
  • Correlation of muscle strength, posture, and joint degeneration.

Main Results:

  • Muscle imbalance, influenced by power and lever arm differences, is a primary driver of medial knee arthrosis.
  • Aging significantly amplifies muscle imbalance, contributing to joint degeneration and injury.
  • Early diagnosis allows for less invasive treatments, including muscle correction and partial meniscectomy, yielding positive results.

Conclusions:

  • Muscle imbalance is a key factor in medial knee arthrosis development and progression.
  • Conservative management focusing on muscle reeducation is effective in early stages.
  • Timely intervention can prevent the need for more extensive surgical procedures in advanced knee degeneration.
