This review examines cartilage degeneration and repair, linking osteoarthritis to physical activity. Intensive exercise may increase osteoarthritis risk, while rehabilitation shows therapeutic potential.
Area of Science:
- Biomedical Engineering
- Orthopedics
- Sports Medicine
Background:
- Articular cartilage is crucial for joint function, susceptible to degeneration.
- Osteoarthritis (OA) is a debilitating joint disease with complex causes.
- Physical activity's role in cartilage health and OA pathogenesis is debated.
Purpose of the Study:
- To review current knowledge on articular cartilage degeneration and repair.
- To explore the relationship between physical activities and osteoarthritis.
- To discuss OA pathogenesis, treatment, and rehabilitation.
Main Methods:
- Literature review of PubMed and ScienceDirect databases (1994-2003).
- Keywords: cartilage, osteoarthritis, exercise, rehabilitation.
- Analysis of mechanical biology, chondrocyte function, and clinical rehabilitation trials.
Main Results:
- Mechanical stresses significantly alter chondrocyte and cartilage structure/function.
- Physical activity and joint injury can modulate cartilage matrix turnover and increase OA risk.
- Intensive physical exercise in humans appears associated with OA development.
Conclusions:
- Current cartilage repair methods do not fully restore normal tissue; selected procedures offer benefits.
- OA pathogenesis remains incompletely understood.
- Rehabilitation programs may be beneficial in managing osteoarthritis.

Growth of Cartilage and Bone Tissue
Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...
