Outcome measures
Primary outcome
The general average physical activity score, derived from the Actometer- data, and determined by the number of accelerations per 5-min periods will be determined during a 14-days period.
Secondary outcome
Self-reported daily Activity, Pain and Fatigue severity
Background summary
Total hip arthroplasty with impacted bone grafts show a tendency for better long-term prosthesis survival than hip arthroplasty patients without acetabular bone reconstruction. To determine whether activity levels play a role in prosthesis survival, a prospective observational cohort study was designed to determine activity levels in young primary cemented total hip arthroplasty patients under 50-years.
Physical activity levels are determined by actometer-data obtained during a 14-day period and by self-reported daily Activity, Pain and Fatigue severity questionnaire.
Study objective
The outcome of primary cemented total hip arthroplasty in young patients under 50-years implanted at our Department shows promising long-term prosthesis survival rates. However, many young patients have already an acetabular bone stock deficiency at surgery and they are the more demanding hips. In case of acetabular deficiency, these defects are reconstructed with impacted bone-grafts. Total hip arthroplasty with impacted bone grafts showed a tendency to even better long-term survival rates than hip arthroplasty without acetabular bone reconstruction, which is remarkable. Insight into the level of activity is necessary to determine if these good results are related to lower activity levels in the acetabular reconstruction group or related to the acetabular bone-grafting technique.
