Adaptation of High Activity Arthroplasty Score to Turkish

The HAAS questionnaire, developed in 2010, is self-reported and comprises the four items walking, running, stair climbing, and the activity level [20]. The response level for each item ranges from normal function to serious limitation. The patient selects the highest possible level of his functional ability for each item. A point system for each item is applied whereby a higher score indicates a higher functional ability. The total score ranges from 0 to 18 points. The original version provides no instruction regarding missing answers.

The Knee Injury and Osteoarthritis Outcome Score (KOOS) is a knee-specific instrument, developed to assess the patients' opinion about their knee and associated problems. The KOOS evaluates both short-term and long-term consequences of a knee injury. It holds 42 items in 5 separately scored subscales; Pain, other Symptoms, Function in daily living (ADL), Function in Sport and Recreation (Sport/Rec), and knee-related Quality of Life (QOL). A Likert scale is used, and all items have five possible answer options scored from 0 (No Problems) to 4 (Extreme Problems) and each of the five scores is calculated as the sum of the items included. Scores are transformed to a 0-100 scale, with zero representing extreme knee problems and 100 representing no knee problems

The 36-Item Short Form Survey (SF-36) is an oft-used, well-researched, self-reported measure of health. It stems from a study called the Medical Outcomes Study. It comprises 36 questions which cover eight domains of health:

• Limitations in physical activities because of health problems.
• Limitations in social activities because of physical or emotional problems
• Limitations in usual role activities because of physical health problems
• Bodily pain
• General mental health (psychological distress and well-being)
• Limitations in usual role activities because of emotional problems
• Vitality (energy and fatigue)
• General health perceptions

The FJS-12 was developed to identify the awareness of an artificial joint (hip or knee) during activities of daily living. It uses a 5-point Likert response format (0, never; 1, almost; 2, seldom; 3, sometimes; and 4, mostly) consisting of 12 items that assess "the patient's ability to forget the artificial joint in everyday life" following activities of daily living -in bed at night; sitting in a chair (>1hr); walking (>15 min); taking bath; traveling in a car; climbing stairs; walking on uneven ground; standing up from a low sitting position; standing for long periods; doing housework or gardening; taking a walk or hiking, and involving in a sports activity. The raw scores are transformed to range from 0 to 100 points. High scores indicate a good outcome, which means a high degree of "forgetting" the joint.
