- Structure of
cartilage
- Cells
- Chondroblasts + Chondrocytes
- Matrix
- Ground substance +
elastic and collagen fibres
- Types
- Hyaline cartilage
- collagen and elastic fibres
are present in equal
amounts
- Supports and reinforces
- Found in: fatal skeleton,
articular surfaces, costal
cartilage, and cartilage of
nose, trachea, and larynx
- Elastic cartilage
- elastic fibres are present in
large amounts
- maintains shape and allows
flexibility
- Found in: external ear and
epiglottis
- Fibrocartilage
- collagen fibres are present in
large amounts
- strength and ability to absorb
compressive shock
- Found in:
Intervertebral discs
Pubic symphysis
Menisci
- Osteoarthritis
- Risk factors
- Age/sex, disease,
genetics,
occupation, injury,
weight, and muscle
weakness
- Clinical presentation
- pain, stiffness, swelling,
tenderness, and
crepitus
- Pathogenesis
- trauma of genetic factors
- damage to articular cartilage or
failure of abnormal cartilage
under normal joint loading
- increase water in joint space
- Erotion
- Eburnation
- Bone cysts,
osteophytes, sclerosis,
and joint space
narrowing
- Treatment
- 1st line:
- Therapy: Physical therapy,
occupational therapy, Tai
chi yoga
- 2nd line:
