Total knee replacement (TKA) is a surgical procedure to increase the function of the knee joint. However, in the postoperative period, it takes a long time for patients to gain independence and adapt to daily life, and they need information and support. The aim of this study is to determine the effect of the increased perioperative communication program (IPCP) in patients with TKA on early postoperative complications.

Total knee replacement (TKA) is a surgical procedure to increase the function of the knee joint. However, in the postoperative period, it takes a long time for patients to gain independence and adapt to daily life, and they need information and support. The aim of this study is to determine the effect of the increased perioperative communication program (IPCP) in patients with TKA on early postoperative complications.

The population of this study will consist of patients who applied to Ankara Bilkent City Hospital, Orthopedics and Traumatology Outpatient Clinic due to knee osteoarthritis and who are planned to undergo elective total knee arthroplasty. Patients who are planned for elective primary unilateral knee arthroplasty, have a smartphone, are literate, have no communication problems and agree to participate in the study will be included in the study; Patients with revision total knee arthroplasty, bilateral total knee arthroplasty, speech and hearing disabilities, cognitive problems such as Alzheimer's and dementia, and patients who do not agree to participate in the study will be excluded from the study. The sample of the research is; it was determined as 70 patients by G. Power analysis based on the correlation coefficients in a sample study. 35 of the patients will be assigned to the intervention group (IG) and 35 to the control group (CG). Patients in the CG will receive routine perioperative care, while patients in the IG will be included in the IPCP. All patients will be followed for one month after discharge. IPCP consists of 8 informative contents such as preoperative preparations, surgical procedure, pain management, first mobilization, knee joint movements, exercise, discharge process, wound care, showering, nutrition, daily living activities, driving, sexual life, postoperative routine control, unexpected situations and etc. These informative contents will send to patients on days 7th, 4t and 1th days before the surgery and on days 1th, 2th, 3th, 5th an 7th days after surgery via whatsapp. Additionally, all participants will follow postoperative one month. Data will collect using Personal Information Form and Problems Experienced After Discharge Form. Data will analyze using IBM SPSS version 23.0.
