Structural Foot Characteristics in People With Midfoot Osteoarthritis: Cross‐Sectional Findings From the Clinical Assessment Study of the Foot
Authors' conclusion
People with midfoot OA have a flatter foot posture compared with controls.
Study context
- Population
- Adults aged 50 years and older registered with four UK general practices who reported foot pain in the past year
- Participants
- 63 vs 63
- Exposure
- Symptomatic radiographic midfoot osteoarthritis (OA) vs matched controls
- Midfoot OAn = 63
- Controlsn = 63reference
- Outcome
- Eleven radiographic measures of foot structure (weightbearing dorsoplantar and lateral radiographs)
Methodological detailscase-control matched 1:1 for sex and age (5-year tolerance), independent sample t-tests, Cohen's d effect sizes
- Case-control matched 1:1 for sex and age (5-year tolerance)
- Independent sample t-tests
- Cohen's d effect sizes
Main finding
As reported in the abstract
Radiographic foot structure measures
Cohen's d (calcaneal-first metatarsal angle, higher in midfoot OA)
0.43
P = 0.018
Midfoot OA
Cohen's d (calcaneal inclination angle, lower in midfoot OA)
0.46
P = 0.011
Midfoot OA
