Study Overview

• Status: Completed
• Conditions: Total Knee Arthroplasty
• Intervention / Treatment: Diagnostic test: Total knee arthroplasty; Diagnostic test: osteoarthritis without surgery; Diagnostic test: control group

Detailed Description

The aim of this study; To evaluate the joint position sense of individuals who met the inclusion-exclusion criteria of the study by examining the retrospective files of individuals who had previously undergone unilateral total knee arthroplasty surgery due to knee osteoarthritis and whose treatments were completed, and to examine the effect of joint position sense on parameters related to balance, physical performance, reaction time, kinesiophobia, pain and stiffness.It is thought that it will be useful to understand the relationship between the individual's balance, reaction time and physical performance parameters by determining the changes in the joint position sense of individuals who have previously undergone unilateral total knee arthroplasty and individuals with knee osteoarthritis. Also, secondarily; it will shed light on the literature about whether all the evaluated parameters are affected only by the presence of the disease or because of surgery.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Knee Position Sense	Knee joint position sense will be evaluated with the mobile application. As the target angle, 15˚, 45˚ and 60˚ knee flexion positions will be determined. For the initial target angle of 15˚ knee flexion, the physiotherapist will passively bring the individual's knee to 15˚ knee flexion and remain in this position for 5 seconds. The individual will be asked to feel and remember this angle, and when he thinks he has come to this angle during the test, he will be asked to say "here" by keeping his knee fixed at that angle. The "estimated target angle" that the person perceives as the "target angle" will be recorded with the phone application. For a target angle, the average of the 3 measurements will be recorded. The deviation angle between the taught target angle and the estimated target angle made by the individual will be calculated.	baseline
Balance	Berg Balance scale, which has Turkish validity and reliability, will be used in the evaluation of balance. Scale; It consists of 14 parameters that evaluate sitting, standing and standing. These parameters are scored between 0 (unable) and 4 (doing safely). The maximum score is 56. As the score decreases, it will be interpreted as the risk of falling increases and the balance is poor.	baseline
Reaction Time	Nelson Foot Reaction Test will be used to evaluate the reaction rate. Individuals will be asked to remove their shoes and sit on the stool. The dominant side will be positioned so that the toe is 2.5 cm away from the wall and the heel is 5 cm away from the wall. The observer will hold the 30 cm long wooden ruler on the wall and at the level of the dominant toe of the individual to be evaluated, count backwards from three, one by one and say zero, and leave the ruler. The individual will be asked to hold the falling ruler with the toe and the value on the tip of the foot at the moment he catches the ruler will be recorded in centimeters. The test will be repeated 5 times, and the average of the 3 values other than the lowest and highest values will be recorded in centimeters. The average value obtained will be put into the formula "Reaction Time= √2 x Distance (cm)/980 cm/s2" and the reaction time will be calculated and recorded in seconds.	baseline
Physical Performance	Timed Up & Go Test (TIGT): This test is frequently used in the evaluation of functional status in individuals with OA and its original name is "Timed Up & Go Test" (TUG). During this test, individuals will be asked to get up from a chair with fixed arms while sitting with their feet in contact with the floor, walk 3 meters, return from the marked place at the end of 3 meters, walk back to the chair and sit on the chair. The duration will be started as soon as the hips of the individuals are out of contact with the chair and stopped when their hips come into contact with the chair after they return, and will be recorded in seconds with a stopwatch.	baseline
Kinesiophobia	Tampa Kinesiophobia Scale will be used in the evaluation of kinesiophobia. The Tampa Kinesiophobia Scale is a 17-question checklist. It is scored between 1 and 4 points on a Likert scale (1 answer I strongly disagree, 4 answer I strongly agree), 4,8,12,16. The calculation of the questions is done by inverting. The score is determined in the range of 17-68 points, and as the score increases, the fear of movement also increases.	baseline
Evaluation of Pain, Function, and Stiffness	WOMAC index in order to determine the severity of the clinical findings in the cases and the effects of the current clinical picture on the daily living activities of the patients; osteoarthritis index will be evaluated. WOMAC consists of 3 parts and 24 questions. There are 5 questions in the pain section, 2 questions in the stiffness section, and 17 questions in the physical function section. The total WOMAC value will be obtained by scoring the answers given by the patients as none/mild/moderate/severe/extreme, respectively, between 0 and 4 points. Then, the scores of each section will be collected within itself and the score for that section will be found. High WOMAC values indicate an increase in pain and stiffness and deterioration in physical function. As a result of the study examining the acceptability, reliability, validity and sensitivity of the Turkish version of the WOMAC OA index, it was shown that the Turkish version of the WOMAC index had good content validity.	baseline
