Fear and pessimism predict poor knee surgery outcomes

In the weird world of pain, fearing the worst is at least partially a self-fulfilling prophecy. Dr. Gary J Macfarlane, regarding a paper on knee replacement results:
“We identified 3 distinct response trajectories in patients undergoing knee replacement. Expectations of pain/limited function and poor coping strategies differentiated the trajectories, suggesting a role for preoperative psychosocial support in optimizing the clinical outcome.”
And so it also seems likely that anything at all that increases patient optimism and confidence would probably help. This is consistent with a large body of relevant evidence on the power of mind-over-pain — which is not an easily controlled power, but a power nevertheless.
It’s also a dilemma for health science reporting and clinicians: truth may be harmful! The discouraging reality about side effects, poor outcomes, and other bad science news may make patients more pessimistic and fearful, and actually cause worse outcomes. But we cannot lie or conceal the truth, either! Awkward. 🎵 The truth may be problematic, but also unavoidable and essential. There is no easy solution to this dilemma.
But consider this: the same confidence and optimism that helps surgical patients almost certainly also applies to outcomes for patients who do not get surgery. •head explodes•
