Evidence suggests that radiographic measures of knee osteoarthritis (K-OA) pathology only weakly correlate with clinical pain. We sought to evaluate possible differences in pain sensitivity and psychosocial distress profiles between K-OA patients with discordant versus congruent clinical pain reports relative to radiographic severity measures.
K-OA patients with high clinical pain in the absence of moderate to severe radiographic OA symptoms display abnormalities in pain processing. The findings were not explained by clinical pain severity alone or the presence of psychosocial distress, suggesting that the discordance between clinical and radiographic OA symptoms may be driven by underlying pathophysiological processes, such as central sensitization.
These findings should be replicated in a larger representative OA sample. If replicated, the findings should spur further research on how this subgroup of OA patients is medically managed.
