ADAPT study

ADAPT was a research study that followed people over one year when they were undergoing hip or knee replacement (a longitudinal cohort study).

In total, 123 patients having hip surgery and 126 having knee surgery took part. Participants were asked to answer questions before surgery, three months after surgery, and 12 months afterwards.

Participants were also asked to walk along a corridor and stand up and down on a box so that researchers could see how their mobility was changing over time. Analysis showed that most improvement happened by the three-month assessment after surgery.
