Pulsed Electromagnetic Field Stimulation in Bone Healing and Joint Preservation: A Narrative Review of the Literature

Abstract

Background: Biophysical stimulation therapy, Pulsed Electromagnetic Fields (PEMFs) and Capacitively Coupled Electric Fields (CCEFs) have significantly increased in the last twenty years. Due to this, it is necessary to have clear information regarding their efficacy, therapeutic indications and expected objectives. Application fields: There is a unanimous opinion regarding the usefulness of applying biophysical therapy on the bone compartment both in terms of the tissue-healing process and the symptoms associated with this situation. Differently, but no less important, positive results were observed in the joint compartment, especially with regard to the inhibition of the inflammatory process. Good results for chondroprotection were obtained in vitro and after a surgical procedure. New studies have shown the effectiveness also in cases of osteoporosis. Conclusions: The effectiveness of PEMFs and CCEFs on the bone-healing process and on joint preservation in the orthopedic and traumatology fields has consolidated evidence in the literature. We have also found positive results for symptoms and patient compliance with rehabilitation therapies. Therefore, their notable applications can be envisaged in the fields of prosthetic surgery and sports medicine.
