Objective:
The aim of this study was to culturally adapt the Osteoarthritis Knowledge Scale (OAKS) into a simplified Chinese version and to evaluate its measurement properties among Chinese-speaking populations.
Methods:
The OAKS scale was translated and cross-culturally adapted following COSMIN guidelines. A total of 368 participants were recruited, including individuals with knee or hip osteoarthritis (OA), healthcare professionals, and individuals without OA. The study evaluated the scale's internal consistency, test-retest reliability, and factor structure using Exploratory Factor Analysis (EFA).
Results:
The translated OAKS scale demonstrated acceptable levels of reliability across different groups. Cronbach's alpha for the KOAKS was 0.70 overall, with subgroup values ranging from 0.70 to 0.71. For the HOAKS, Cronbach's alpha was 0.77 overall, with subgroup values ranging from 0.63 to 0.72. Test-retest reliability showed high Intraclass Correlation Coefficient (ICC) values for both scales (KOAKS: ICC = 0.960; HOAKS: ICC = 0.982). EFA revealed that the overall OAKS explained a substantial portion of the variance (60.51%), with KOAKS accounting for 59.35% and HOAKS accounting for 54.68% of the variance.
Conclusion:
The simplified Chinese version of the OAKS is a reliable tool for assessing OA knowledge among Chinese-speaking patients, healthcare professionals, and the general public. The findings highlight the necessity for continuous improvement and adaptation of educational interventions to address specific knowledge gaps within the Chinese context.

Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...
01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:09Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
