The Effect of TENS on Early Outcomes in Incisional Wounds After Total Knee Replacement Incisional wounds heal within 3 to 4 weeks, consistent with the normal healing process.

However, pain is experienced during the wound healing phase, which can negatively impact patients' recovery. Pharmacological and non-pharmacological methods are used to control pain in the early postoperative period. TENS, in particular, is notable as a non-invasive method, aiming to alleviate pain with low-voltage electrical currents. Studies report that TENS significantly reduces postoperative incisional wound pain. However, the literature demonstrates a limited number of studies on comprehensive pain assessment of incisional wounds using TENS. However, because postoperative incision pain negatively impacts patient outcomes (e.g., pain, mobilization, coughing, sleep), the effectiveness of the analgesia method must be measured. Early pain should be comprehensively assessed to plan effective treatments and improve patient recovery. In this context, the aim of the study was to evaluate the effect of TENS on early pain management in incisional wounds after total knee replacement. The study was designed as a randomized controlled trial. Patients meeting the study's sample criteria will be included. Data collection tools will be a Personal Information Form and the Revised American Pain Society Patient Outcomes Questionnaire (GGAADHSA), which measures the patient's pain assessment in the first 24 hours. TENS will be applied twice (12 hours apart) for 30 minutes each time within the first 24 hours after surgery to the experimental group, while the control group will receive standard treatment. The GGAADHSA questionnaire will be administered once to both groups 24 hours later. The study will evaluate the effect of TENS on early patient outcomes in incisional wounds and contribute to clinical practice in terms of postoperative recovery.
