A Moderate-Intensity Static Magnetic Field Enhances Repair of Cartilage Damage in Rabbits

Background and AimsElectromagnetic fields have been proposed to enhance healing of cartilage defects by stimulation of chondrocyte proliferation, proteoglycan synthesis as well as decreasing pain and improving motion in osteoarthritic patients. However, the effects of a moderate-intensity static magnetic field on cartilage repair have not been investigated. This study tries to determine the effects of a moderate-intensity permanent magnetic field of 40 mT on cartilage repair.MethodsDefects of 3 mm in diameter and 6 mm in depth were made on the we
