THA: total hip arthroplasty; TKA: total knee arthroplasty; CI: confidence interval; n.a. if <50 cases were at risk.

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.
