Knee Replacement and Sarcopenia

Not yet recruiting

• Conditions: Sarcopenia; Knee Prosthesis; Knee Arthroplasty, Total

• Registration Number: NCT06635356
• Lead Sponsor: Istanbul Physical Medicine Rehabilitation Training and Research Hospital

Brief Summary

The presence of sarcopenia in patients planned to undergo knee prosthesis and the effect of knee prosthesis on sarcopenia will be investigated

Detailed Description

Volunteer patients who will undergo knee replacement surgery in orthopedic clinics located in the Istanbul region and who meet the inclusion criteria will be recruited. A total of 31 volunteers will be included in the study.

First, all patients will be asked about their gender, age, height, weight, education, smoking, lifestyle, additional diseases, and treatments they have received. Then, a brief orthopedic evaluation will be performed on the patient. TANITA BIA analysis and grip strength measurement from the dominant hand will be performed on all patients before the operation, at 1 month and 3 months after the operation. Maximal voluntary grip strength will be measured with a hand dynamometer. Measurements will be made three times. For this measurement, the subject will be asked to hold a maximal voluntary grip for five seconds. There will be a ten-second rest period between the three tests. Measurements will be made with the JAMAR Plus+ (by Sammons Preston) hand dynamometry device. Before the test measurements, the patient will be shown how to use the device as an application. The highest of the three measured values will be taken. In addition, the calf circumference will be measured. While the patient is standing, the measurement will be made with a tape measure from the thickest point of the right and left calves without squeezing the skin. The same measurement will be repeated with the patient seated. At the same time, patients will be evaluated with walking speed test, sit-to-stand test, SARC-F, FRAIL Frailty Questionnaire, Mini Nutritional Assessment, EQ-5D General Quality of Life Scale, GLIM Test, Barthel Activities of Daily Living Index, CIRS Scale before the operation, 1st month and 3rd month after the operation.

When performing the walking speed test, the patient will be asked to walk as they normally do. A 4-meter or 3-meter walking speed test will be performed and a single test will be scored. Measurements will be made twice and the fastest will be evaluated.

In the sit-to-stand test, the person will be asked to try to get up without using their arms. If they cannot complete the test or can get up using their arms, the patient will receive 0 (zero) points. If they can get up using their arms, the repeated sit-to-stand test will be performed. In the repeated sit-to-stand test, the person will be asked to sit down and get up from a chair 5 times in a row without using their arms. Scoring will be between 0-4 depending on the time spent.

Primary Outcome Measures

Name	Time	Method
Calf circumference measurement	before surgery, 1st month after surgery, 3rd month after surgery	Calf circumference is an anthropometric measurement that indicates fatfree muscle mass and has been considered by the World Health Organization (WHO) the most sensitive index for evaluating the decrease in muscle mass.; While the patient is standing, the measurement will be taken with a tape measure from the thickest point of the right and left calves without squeezing the skin.
Handgrip strength	before surgery, 1st month after surgery, 3rd month after surgery	Handgrip strength will be measured using a Jamar hand grip dynamometer (Model 5030J1, Sammons Preston Rolyan, Bolingbrook, Illinois, USA). Measurements will be taken 3 times in a sitting position with the elbow flexed to 90° and the wrist in neutral position. The measured maximal grip strength will be recorded as hand grip strength.
Skeletal muscle mass	before surgery, 1st month after surgery, 3rd month after surgery	Skeletal muscle mass will be evaluated using a Tanita DC-360 multi-frequency body composition analysis device.
Body Mass Index (BMI)	before surgery, 1st month after surgery, 3rd month after surgery	BMI will be calculated as weight (kg) divided by height2 (m2)
