Transcutaneous electrical nerve stimulation for postoperative pain relief after total knee arthroplasty . Transcutaneous electrical nerve stimulation ( TENS ) has been used to treat chronic pain syndromes and has been reported to be of some utility in the treatment of postsurgical pain . A randomized , blinded , placebo-controlled trial was designed to evaluate the utility of TENS after total knee arthroplasty . Patients were randomly enrolled into patient-controlled anesthesia ( PCA ) alone , PCA plus TENS , or PCA plus sham TENS . The cumulative dose of morphine by PCA for each group was used as the end-point of the study . There was no significant reduction in the requirement for patient-controlled analgesia with or without TENS . We conclude that there is no utility for TENS in the postoperative management of pain after knee arthroplasty .
