Brief Summary

Total Knee Replacement (TDP) is considered the best treatment option available when conservative methods such as anti-inflammatory or physical therapy fail. However, TDP surgeries are also a serious trauma that causes severe pain in patients. Uncontrollable pain exacerbates the stress response and causes morbidity and mortality by causing negative changes in the neuroendocrine, respiratory, cardiovascular, gastrointestinal, renal and immune systems. Therefore, the relief of pain has very important effects on the patient's recovery process, functional status and quality of life. Transcutaneous Electrical Nerve Stimulation (TENS) is one of the non-pharmacological methods for pain relief in TDP surgeries. This study was planned as a randomized controlled trial to examine the effects of TENS after TDP on acute pain, functionality and quality of life.

Outcome Measures

Primary Outcomes (1)

  • Visual Analogue Scale (VAS) Change

    The Visual Analogue Scale (VAS) is a scale where the pain is evaluated between 0-10 (0; no pain, 10; unbearable pain) on a ruler that can be used horizontally or vertically, on which the patient can mark his or her own pain.The length of the distance from the point where there is no pain to the point marked by the patient is measured in centimeters and the numerical value found shows the severity of the patient's pain. It is used in various populations, including patients with total knee replacement, to evaluate both the severity of pain and the effectiveness of treatment/intervention on pain.

    1st day of admission to the clinic change VAS score at before intervention, 24th postoperative hour change from baseline VAS score before the intervention, postoperative 48th, 72th and 96th hours,15th day change from baseline VAS score after intervention

Secondary Outcomes (2)

  • Western Ontario and McMaster Universities Arthritis Index (WOMAC) Change

    1st day of admission to the clinic change WOMAC score at before intervention, change from baseline the WOMAC score at 4th postoperative day, 15th postoperative day change from baseline WOMAC score

  • The Quality of Life Scale (SF-36) Change

    1st day of admission to the clinic change quality of life score at before intervention, 15th postoperative day change from baseline quality of life score

Study Arms (2)

Control group

NO INTERVENTION

When the patients are admitted to the clinic, the patient identification form and the SF-36 Quality of Life Scale will be filled by face-to-face interview method. On the morning of the operation, before the operation, the GCS, EHA and WOMAC index will be filled. After the operation, the pain during rest and movement (24., 48., 72., 96. hours and 15. days) will be evaluated with VAS. The total amount of analgesics used by the patients will be recorded by looking at the nurse observation form records where the nurses recorded the drugs they administered at the 24th, 48th, 72nd, and 96th hours after the surgery, and by asking the patients on the 15th day after discharge. The WOMAC Index will be re-administered at discharge and on the 15th day, and the VCS, ROM, and the SF-36 Quality of Life Scale on the 15th day.

Intervention group

EXPERIMENTAL

Unlike the control group, the patients in the intervention group will be informed about TENS and the application will be made. The electrodes of TENS will be placed 2 cm below and 2 cm above the incision site. TENS settings Frequency: 100 Hz; Pulse width (duration): 150 μs; Flow Intensity (Amplitude): By adjusting it to be 30 mA, TENS will be applied 3 times a day (09.00, 13.00, 17.00) for 20 minutes during the time the patients stay in the clinic (3 days).It is planned to start the TENS application the day after the surgery.

Device: TENS (Transcutaneous Electrical Nerve Stimulation) Application

Interventions

Conventional (traditional) TENS will be applied to the patients. The frequency will be 100 Hz, the pulse width (time) will be 150 μs, the current intensity (amplitude) will be 30 mA. In addition to routine care and treatment, TENS will be applied to intervention group patients.

Due to the nature of the study, patients will not be left blind. The assignment to the groups will be carried out by an independent researcher, and the group will be notified via telephone after the practitioner researcher has approved, evaluated the criteria and performed the pre-tests. At the same time, groups will be named A and B and researchers will be blinded during statistical analysis and reporting.The questionnaires to be applied to the patients included in the study will be administered by an independent researcher.
