Total knee arthroplasty (TKA) is among the major advancements for the treatment of knee pain and improvement of physical function when conservative management fails to comply with. The success of this arthoplasty results in more functional mobility and better quality of life. However, management of pain after TKA in post-operative period is a big challenge to deal.
Transcutaneous electrical nerve stimulation is a cost effective, non-invasive electrotherapeutic modality used in alleviating pain in both acute and chronic conditions affecting neuromusculoskeletal system of the body.
