Effect of pulsed electromagnetic field therapy in patients undergoing total knee arthroplasty: a randomized controlled trial
לצפייה במחקר >
We compared the clinical outcome of 33 patients undergoing TKA randomly assigned to the control or the pulsed electromagnetic field group .
Methods
Magnetic therapy was administered postoperatively. Patients were assessed before surgery and then at one, two and six months postoperatively using international scores.
Results:
One month after TKA, pain, knee swelling and functional score were significantly better in the treated compared with the control group.
Pain was still significantly lower in the treated group at the six month follow-up.
Three years after surgery, severe pain and occasional walking limitations were reported in a significantly lower number of patients in the treated group.
Conclusions
Advantages deriving from early control of joint inflammation may explain the maintenance of results at follow-up. Magnetic therapy should be considered an effective completion of the TKA procedure.
