Total knee arthroplasty (TKA) is a commonly performed surgical procedure aimed at reducing pain, restoring joint function, and improving quality of life, particularly among older women. Despite improvements in pain and functional outcomes following TKA, findings regarding balance, fall risk, and gait performance remain inconsistent. Impairments in these parameters may adversely affect daily activities, independence, and overall quality of life.
Unlike previous studies that have primarily focused on one or two outcomes, this study will comprehensively evaluate balance, fall risk, gait performance, and quality of life in postmenopausal women who have undergone TKA. The findings are expected to provide a more holistic understanding of long-term functional outcomes following TKA and contribute to the planning of rehabilitation programs. Therefore, the aim of this study is to compare balance, fall risk, gait performance, and quality of life between postmenopausal women who have undergone TKA and healthy postmenopausal women.

Presence of any neurological, vestibular, visual, cardiopulmonary, auditory, or cognitive deficits that may affect measurements.

Single Leg Standing Test
Single Leg Standing (SLJ) Test: Balance assessment will be performed using the single leg standing (SLJ) test. In the SLJ test, participants will be asked to stand with their extremities on the side that has not undergone surgery raised. The duration of the test in this position will be recorded. If the participant completes this position for 30 seconds, the test will be recorded as successful. Sarac et al. determined the validity and reliability of the SLJ test in TDA patients as an intraclass correlation coefficient \[ICC\]=0.74 (0.48-0.87).
30-Second Sit-to-Stand Test
For the test, the individual sits in the middle of a chair without armrests, with a seat height of 43.18 cm, with their back straight, arms crossed over their chest, and feet flat on the floor. Upon the "Start" command, they rise from the chair without pushing off with their arms, stand upright, and then sit down again. Prior to the evaluation, the individual is assessed for two sit-to-stand repetitions to ensure they have learned the procedure. The number of correct standing repetitions within 30 seconds is recorded as the test value.
Timed Up and Walk Test
The individual is asked to stand up from a chair, walk 3 meters at a safe and normal pace, turn around, walk back, and sit back down in the chair. The time is recorded in seconds. The test will be initiated with the patient's feet flat on the floor and their arms resting on the armrests of the chair. Three repetitions will be performed, and the best result will be recorded.
10-Meter Walking Test
The 10-meter walking test will be used to assess walking ability. In this test, the individual will be asked to walk at their normal pace in a pre-measured 10-meter area (with or without walking aids). The timer will start when the individual's foot is on the starting line and end when they cross the finish line. Two measurements will be taken, and the best value will be recorded in meters per second (m/s).
