Welcome to LROI Report 2023
This online annual report 2023 of the Dutch Arthroplasty Register (LROI) contains trends and outcome information on primary and revision hip, knee, ankle, shoulder, elbow, wrist and finger arthroplasties in the Netherlands between 2007 and 2022. Since 2007, the LROI has been collecting data on hip and knee procedures, on ankle, shoulder, and elbow procedures since 2014, and on wrist and finger procedures since 2016.
What’s new
Survival outcomes are available for all joints

Survival outcomes of hip, knee, ankle, shoulder and elbow arthroplasties are expanded. Examples are:
- survival by year of surgery by fixation of primary THA and TKA;
- survival by year of surgery by approach of primary THA;
- survival according to province of residence of the patient of THA and TKA;
- survival according to articulation and PE type of THA and TKA;
- survival by year of reverse TSA, anatomical TSA and hemi;
- survival according to patient characteristics of ankle and total elbow arthroplasties;
- survival by year of revision THA and TKA.
This year PROMs response rate are shown by hospital volume:
- of patients who underwent a primary total hip arthroplasty for osteoarthritis;
- of patients who underwent a primary total knee arthroplasty for osteoarthritis;
- of patients who underwent a primary total (anatomical or reverse) shoulder arthroplasty for osteoarthritis.
