Pulsed Electromagnetic Fields and Tissue Engineering of the Joints

Area of Science:

• Biomedical Engineering
• Orthopedics
• Regenerative Medicine

Background:

• Bone and joint health rely on chemical and physical signals.
• Pulsed electromagnetic fields (PEMF) are increasingly recognized for treating bone fracture nonunions.
• The piezoelectric properties of bone, discovered in 1953, underpin PEMF research, leading to FDA approval for fracture healing.

Purpose of the Study:

• To systematically review the literature on PEMF's influence on joints, including articular cartilage, tendons, and ligaments.
• To explore the potential of PEMF in joint regeneration, particularly in osteoarthritis (OA).

Main Methods:

• Systematic literature review of publications from 2000 to 2016.
• Focus on studies investigating PEMF effects on joint tissues.

Main Results:

• PEMF stimulates chondrocyte proliferation, differentiation, and extracellular matrix synthesis.
• PEMF promotes the release of bone morphogenetic proteins and anti-inflammatory cytokines.
• Clinical studies show beneficial effects of PEMF on improving function in osteoarthritis knees.

Conclusions:

• PEMF demonstrates potential for joint regeneration and treating osteoarthritis.
• Further systematic studies are required to elucidate the precise mechanisms of PEMF action on joint tissues.
• PEMF offers novel therapeutic opportunities in regenerative medicine for joint conditions.
