The Effect of Tele-Health Application on Functional Status, Self-Care Ability and Activities of Daily Living in Individuals Undergoing Total Knee Arthroplasty Surgery ((TKA-TELECARE))

The Effect of Telehealth-Based Follow-Up on Functional Status, Self-Care Ability, and Activities of Daily Living in Patients Undergoing Total Knee Arthroplasty: A Randomized Controlled Trial

Osteoarthritis, defined as a degenerative joint disease, is a chronic, non-inflammatory condition characterized by deterioration of joint cartilage and new bone formation on joint surfaces and margins. Due to osteoarthritis, the number of total knee arthroplasty (TKA) procedures has increased. Patients undergoing TKA often experience difficulties in meeting their self-care needs and performing daily living activities due to impaired functional status. During the postoperative home care period, nursing support is critical in enhancing patients' functional status, self-care ability, and independence in daily activities. Therefore, this study aims to examine the effect of telehealth services on functional status, self-care ability, and daily living activities in patients undergoing TKA. The study is designed as a randomized controlled trial. The sample will consist of patients who undergo TKA in the Orthopedics and Traumatology Department of Sakarya University Training and Research Hospital between April 2024 and April 2025. Patients in the intervention group will receive telehealth-based nursing follow-up, including education and counseling for 14 days after discharge. The control group will receive only standard discharge education. Data will be collected using the Structured Patient Information Form, WOMAC Osteoarthritis Index, Self-Care Agency Scale, Barthel Index of Activities of Daily Living, Subcutaneous Heparin Injection Evaluation Form, and Telephone Interview Form. Based on power analysis, a total of 54 participants are needed to achieve 85% power at a 95% confidence level and medium effect size (p < 0.05). To account for potential data loss, the sample size was increased to 60. It is anticipated that utilizing telehealth services for postoperative nursing follow-up will contribute significantly to patient safety, healthcare costs, and the nursing discipline.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in functional status, as measured by the WOMAC Osteoarthritis Index, from baseline (pre-operative) to 14 days post-discharge.
Time Frame: From baseline (preoperative assessment) to 14 days after discharge
Functional status will be assessed using the WOMAC Osteoarthritis Index, which evaluates pain, stiffness, and physical function. Scores will be recorded at baseline (before surgery) and at the end of a 14-day telehealth-based follow-up period post-discharge.
From baseline (preoperative assessment) to 14 days after discharge

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in self-care ability measured by the Self-Care Agency Scale
Time Frame: From baseline (preoperative assessment) to 14 days after discharge
Self-care ability will be assessed using the Self-Care Agency Scale. The scale evaluates the individual's capacity to meet their own self-care needs. Scores will be obtained before surgery and after the 14-day telehealth follow-up period.
From baseline (preoperative assessment) to 14 days after discharge
