Biophysical stimulation and the periprosthetic bone: is there a rationale in the use of Pulsed Electromagnetic Fields after a hip or knee implant?


The biophysical stimulation of bone and cartilage, using Pulsed ElectroMagnetic Fields (PEMF), covers many different aspects of bone formation and/or cartilage repair, such as healing of delayed or non-union of fracture, bone necrosis, osteocartilagineous defects. To date there are no specific data on the effects of PEMFs in osteointegration of prosthetic implants but there are some papers that denote clinical advantages, in terms of early recovery, in patients treated with these procedures. Considering these clinical applications, PEMF stimulation around hip or knee joint implants could be useful to reduce the bone oedema, pain and to reduce excessive bone reabsorption around the femoral stems.
