Principal investigator: Prof. Dr. R.W. Poolman
Contact:  L.A.C. Roubos & A.J. Rasker

The HAKA study compares standard check-ups with on-demand check-ups following a total hip- or knee replacement surgery and consists of three work packages (WP).


The inclusion phase for the HAKA study is ongoing. Patients who are on the waiting list for a total hip or knee replacement or had surgery 10 years ago in one  of the participating centre may be eligible for participation.


WP1: A stepped wedge cluster randomized trial focusing on standard follow-up one year after surgery.


WP2: A three-arm randomized controlled trial (RCT) focusing on standard follow-up 10 years after surgery.


WP3: A qualitative study focusing on whether discontinuing standard follow-ups is acceptable to patients and healthcare providers.
