KOOS-12 Score in Knee Osteoarthritis Patients

Osteoarthritis (OA) is a common condition that affects the joints, causing significant pain and disability. As the population ages and unhealthy lifestyle habits become more common, the prevalence and impact of OA continue to grow. This study focuses on knee OA and aims to understand the effectiveness of various non-surgical treatments. The main goal is to determine how responsive patients are to these treatments and identify the minimal clinically important difference in the Knee Injury and Osteoarthritis Outcome Score-12 (KOOS-12), a measure used to assess the condition of patients with knee OA. Participants in this study will be asked to complete a questionnaire known as the Global Rating of Change (GRC). This questionnaire will ask them to compare their current condition to their condition at the start of the study, using a scale ranging from -7 (a very great deal worse) to 7 (a very great deal better). Based on their responses, participants will be categorized into either a 'change' group or a 'no change' group. Additionally, the KOOS-12 score will be used to evaluate pain, function, and quality of life. Each item in this score ranges from 0 to 4, with a mean score of 100. A score of 0 indicates severe functional difficulties, while a score of 100 indicates normal function.
