Effect of Pre-op Patient Education on Functional Outcomes After TKA
Condition: Knee Arthropathy
MeSH terms: Joint Diseases
Study type: Interventional

Summary: 
      This study aims to evaluate the effect of preoperative patient education program on
      functional mobility, gait, postural control, and kinesiophobia level in subjects with TKA.
      Patients of both gender will be recruited unilaterally in the city of Florianopolis and
      referred by an orthopedist to the Physiotherapy Clinic of UDESC. They are divided into two
      groups: one that will receive verbal guidance and a booklet with related information such as
      your physical condition as well as signs and symptoms in the postoperative period and a group
      that will receive only verbal guidance.Both groups will be evaluated by a blind evaluator in
      the preoperative and postoperative periods (6 weeks and 6 months). The evaluations will be
      divided into five stages. Anthropometric measurements of the individual will be made and then
      the WOMAC functionality questionnaire and the Kinesiophobia Cover Scale will be applied.Then
      the individual will walk for 5 meters for three-dimensional gait analysis and
      electromyographic analysis of the quadriceps and femoral biceps. The evaluation of functional
      mobility by Timed Up And Go and assessment of postural control in an equilibrium platform
      will also be performed. Statistical data will be analyzed by analysis of variance 3x2
      considering factor time (pre, post 6 weeks and post 6 months) and groups (with and without
      information leaflet). The value of p will be 0.05.
    

Detailed description: 
      The study will be developed in the dependencies of the Laboratory of Biomechanics of the
      Center for Health Sciences and Sports of UDESC. In the preoperative period the subjects will
      be informed about their physical conditions as well as signs and symptoms of the
      postoperative period. One group (GI) will receive this information verbally and one leaflet
      while the other group (GC) will receive only verbal information. The allocation in these
      groups will be through a lottery, carried out by a member of the team who will not
      participate in the evaluation stages.

      This staff member will read the booklet individually for each GI participant, in a reserved
      room, before handing out the leaflet to take home. GI participants will be encouraged to
      reread the information in the home environment and will be asked about the completion of this
      in the following steps by the staff member responsible for the blinding.

      All participants included in the study will perform the kinematic, kinetic and
      electromyographic gait analysis as well as evaluation of fear of movement, functional
      mobility and self-perceived functionality in the pre (baseline)-and postoperative period (6
      weeks and after 6 months).

      The total duration of each evaluation will be approximately 2 (two) hours and 30 (thirty)
      minutes and all collections will be carried out by the same team. The participant will be
      allowed to stop the test if they feel pain or become fatigued.
