Full-thickness burn formation after the use of electrical stimulation for rehabilitation of unicompartmental knee arthroplasty.

Electrical stimulation and interferential current are commonly used modalities in the physical rehabilitation of patients who have undergone joint arthroplasty surgery. Sparse data are available in the literature regarding potential complications from using these modalities. We report on a patient who underwent a unicompartmental knee arthroplasty with a subsequent full-thickness skin burn over the metal implant after electrical stimulation and interferential current modalities in physical therapy.
