“Digital Technology Package” Reduces Pain After TKA — Here’s Why Not to Use It

What’s the Claim?

It’s not every day that we recommend taking a pass on a paper published in one of the JAMA family journals, but here goes. A randomized trial evaluating a “digital technology package” (exercise app, fitness tracker, and online health coaching) that sought to reduce pain after TKA found no benefits to the intervention in terms of pain on their most-definitive adjusted analysis 3 months after surgery, a less-than-one-point reduction out of 10 in their unadjusted analysis on pain, and only small (likely clinically unimportant) benefits in terms of secondary endpoints like reducing sedentary behavior out to a year after surgery.
