Online education group received an online education session prepared by the researchers, covering dislocation precautions, potential complications, and home exercise programs.

The Turkish version of the Western Ontario McMaster University Osteoarthritis Index (WOMAC), was used. The index includes 24 items divided into three subscales: pain (5 items, maximum score 20), stiffness (2 items, maximum score 8), and physical function (17 items, maximum score 68). Higher scores indicate greater pain and stiffness and poorer physical function.

The World Health Organization Quality of Life-Bref (WHOQOL-BREF) is used for general perceived quality of life. The WHOQOL-BREF consists of 26 items assessing general perceived quality of life across physical, psychological, social, environmental, and national environment domains. Each domain is scored separately on a scale up to 20 or 100, with higher scores reflecting better quality of life.

Pain intensity was assessed using the Visual Analog Scale (VAS). The VAS was used to evaluate pain at rest, during sleep/night, and while walking. The scale consists of a 10-cm horizontal line, with 0 indicating "no pain" and 10 representing "the worst pain imaginable." Participants were asked to mark point that best described their pain, and the distance from the 0 point was measured in centimeters.

The Lawton-Brody Instrumental Activities of Daily Living (IADL) scale assesses individuals' ability to perform instrumental daily activities. Scores range from 0-8 (dependent), 9-16 (partially dependent), and 17-24 (independent).
