Video-Assisted Education for Patients With Knee Replacement
Condition: Quality of Life
Study type: Interventional

Summary: 
      Total knee replacement (TKR) is the most effective treatment modality for the correction of
      knee deformities, increasing the knee functions (KF), relieving pain, and improving quality
      of life (QoL) of patients. According to the health statistics of the Organisation for
      Economic Co-operation and Development (OECD), TKR is most commonly used in Sweden
      (240/100,000), United States (226/100,000), and Austria (215/100,000), while this rate is
      estimated as 67/100,000 in Turkey (OECD, 2017). Although it has been increasingly applied in
      Turkey and worldwide, it is associated with postoperative pain, restricted range of motion
      (ROM), and reduced muscle strength, leading to prolonged recovery process and return to
      activities of daily living (ADLs) with impaired QoL . In addition, inadequate patient
      education on knee care and ADLs following TKR may result in repetitive and uncontrollable
      movements and complications such as severe pain and dislocation. Postoperative complications
      have been shown to be associated with rehospitalization and redo surgery.
    

Detailed description: 
      A comprehensive nursing care and patient education are essential to gain independence and
      return ADLs for patients undergoing TKR. Patient education after TKR increases the success of
      the operation, improving the healing period, and preventing or minimizing postoperative
      complications after discharge. All these improve the KF and QoL of the patients. Patients are
      usually discharged on the first postoperative day, if no complication occurs. Thus, the
      patient education can be instructed within a very limited period of time, mostly without
      repetition. Furthermore, patients and/or their relatives may be anxious after TKR and before
      discharge, leading to difficulties in understanding the education fully or remembering the
      education given in the hospital. As a result, the use of new technological education tools is
      inevitable to use the time effectively for nurses.

      In recent years, disease-specific video-assisted education (VE) has been increasingly used
      for patient education. This tool has certain advantages that patients can watch the video
      repeatedly in every setting, until they understand its content and can remember the content
      than verbal instructions without limitations of recall memory with decreased anxiety and
      improved self-care abilities and, eventually, improved patient outcomes . In the present
      study, we hypothesized that VE could improve the KF and QoL following TKR. Using a holistic
      approach, we, therefore, aimed to investigate the effect of VE on KF and QoL in patients
      undergoing TKR.
    

Intervention name(s): Video-assisted education
Intervention type(s): Other
Intervention description(s): Prior the study, the content and comprehensibility of the VE were evaluated by an orthopedic surgeon, two orthopedic nurses, and a physiotherapist who were not involved in the study and relevant amendments were made based on their suggestions. The preview of the final version of the VE was shown to four patients (10% of the sample) and these patients were excluded from the study. The patients were interviewed by phone calls on a weekly basis and watching VE at home, the frequency of watching VE, and doing home-based exercises were questioned.
