Aim. Actually rehabilitation following anterior cruciate ligament (ACL) reconstruction aims to an even faster time for full recovery. The aim of this study was to verify whether electromagnetic fields produced by a special, registered fiber, enriched with extremely light, noble metals with conductive propriety could reduce the postoperative pain.
Methods. Sixty-one patients, attending at the same rehabilitation centre, after the same operation, performed by the same surgeon have been randomized in two groups: the first group (26) used the knee-band Nexus ES® and the control group (35) used a knee-band indistinguishable for the patients.
Results. As expected, pain (measured by a 0-10 VAS) decreases in both groups from period A (1-3 days after operation) to period B (8-10 days after operation). Differences between groups appear statistically significant 1-3 days after operation (25%), but more clearly 8-10 days after operation (68%), with a lower pain perception in the Nexus ES® group. No adverse events have been reported in the course of the study.
Conclusion. Data collected are preliminary but show a statistical significant difference between the groups during the rehabilitation period; patients in the active group show a lower pain perception after operation through an improvement of tissue exchanges and oxygenation.
