Patient Demographics and Physical Activity in Ankle Osteoarthritis Study

262 patient records from a retrospective cross-sectional study of ankle osteoarthritis at a tertiary referral clinic between June 2022 and October 2024. The dataset includes demographics, radiographic OA severity (Takakura stage), and self-reported physical activity levels (MET-min/week) from the IPAQ-SF questionnaire. It was authored by Woo Sub Kim and published under a CC-BY-4.0 license.

Use Cases

• Analyze correlations between radiographic ankle OA severity and physical activity levels based on Takakura stage and MET-min/week scores.
• Investigate demographic factors (age, sex, BMI) influencing physical activity in patients with ankle osteoarthritis.
• Train models to predict patient-reported outcomes (FAOS) based on clinical and activity parameters.
• Explore sex-stratified differences in the relationship between OA severity and activity types (vigorous, moderate, walking).

Strengths

• 262 patient records with a clear mean age (66.8 years) and BMI (26.3 kg/m²).
• Detailed breakdown of OA severity across four Takakura stages (2, 3a, 3b, 4).
• Multivariable partial-correlation analyses controlling for age, sex, BMI, and pain severity are documented.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is very small (5.5 KB), indicating a limited scope suitable for pilot studies rather than large-scale modeling.
