Effect of midodrine on orthostatic intolerance after hip and knee arthroplasty: A randomized controlled trial (the MObILE study).

Why it matters

OI is a common barrier to early mobilization after arthroplasty, delaying discharge and recovery. This trial provides high-level evidence that a simple, well-tolerated oral agent can reduce OI and syncope, potentially enabling safer, faster rehabilitation.
