Individuals with hand osteoarthritis (OA) with more severely affected joints or a higher number of affected joints are more likely to report hand pain than their peers, a recent study found. Specifically, individuals with hand joints with Kellgren-Lawrence (KL) 3 or 4 have the greatest likelihood of hand pain. Researchers conducted a cross-sectional study with 3,604 participants from the Osteoarthritis Initiative (OAI). Posteroanterior radiographs of the dominant hand were read using a modified KL scale. Hand OA at person level was defined as ≥2 finger joints with KL ≥grade 2. Researchers also explored more conservative definitions of hand OA as well as different sum scores and digit- and row-based scores. They found:
- The majority of definitions of radiographic hand OA were statistically significantly associated with self-reported hand pain.
- In the main analysis, persons with ≥2 finger joints with KL grade >2 were approximately 2 times more likely to self-report hand pain than persons without radiographic hand OA.
- Increasing KL grades and increasing number of joints affected lead to stronger associations.
- Almost all definitions of hand OA were related to pain.
