What is being measured
The primary outcome is the main question the study is designed to answer.
Promis PF Short form (change in self reported capability)
PROMIS Physical Function instruments measure self-reported capability rather than actual performance of physical activities. It is scored from 0-100, a higher score indicates better physical function
Measured: 1 day, 1 week, 2 week, 4 week, 12 weeks after surgery
