Brief Summary

Postural balance can be described as the integration of the information obtained from visual, vestibular and somatosensory systems. Postural stability is achieved by sensory information about the static or dynamic position of the body resulting in an appropriate motor response. Poor postural stability in individuals with knee osteoarthritis often results in an increased risk of falling and decrease in mobility. It has been reported that 40% of knee osteoarthritis patients fall at least once in a year. Total knee arthroplasty (TKA) is a surgical treatment approach applied to individuals with advanced knee osteoarthritis. It has been shown that this method provides an improvement in the postural stability levels of individuals compared to the preoperative period and a decrease in number of falls reported by the patient. Even if this improvement is achieved, postural stability losses can still be observed in individuals undergoing TKA which affect balance performance.

Obesity is defined by an excessive increase in the ratio of body fat mass relative to lean mass. Individuals with a Body Mass Index (BMI) above 30 kg/m2 are defined as obese. Changes in body composition and increased adiposity rate lead to significant locomotor system problems. A decrease in postural control, increased risk of falling or fear of falling can be defined as locomotor system problems. It has been reported that there is a relationship between increased fat ratio and loss of postural stability in adult obese individuals.

In a published study, it was reported that as of 2029, 46% of the population in America will be obese or morbidly obese, and 69% of individuals who have undergone total knee arthroplasty surgery will be obese or morbidly obese. Obesity causes several complications such as increased mortality and increase in likelihood of revision surgery that can be seen after total knee arthroplasty. Therefore, it is clinically important to determine the functional status and balance status in order to reduce the possible long-term complications that may develop in the post-operative period and the risk of falling, especially in obese individuals.

The effects of increasing obesity level on postural stability in individuals undergoing total knee arthroplasty are unknown. In this context, the aim of our study is to compare the postural stability levels of normal, overweight and obese individuals who underwent total knee arthroplasty.

Conditions

Knee Arthritis; Arthroplasty Complications; Obesity; Balance; Distorted

Study Design

• Observational Model Type: CASE_ONLY
• Study Time Perspective: PROSPECTIVE

Interventions

Postural stability measurement

Postural stability of the participants will be evaluated with the NeuroCom Balance Master Static Posturography device. Evaluations will be carried out in the presence of two physiotherapists to prevent the patient from falling. Posturography devices allow us to quantitatively evaluate posture and balance and obtain objective results by measuring postural sway.

Intervention Type: OTHER

Timed Up and Go test

During the Timed Up and Go test, which is applied to evaluate dynamic balance and performance, the participant is asked to get up from the chair, walk 3 meters and sit back on the chair. The participant's time to complete the test is recorded. Completion of the test for more than 10 seconds indicates an increased risk of falling
