A Diagnostic Test Accuracy Study Comparing Biopsy to Aspiration in Shoulder and Elbow Arthroplasty Revision Surgery (BASE Study)
The aim of this study is to compare the diagnostic accuracy of percutaneous aspiration against open biopsy, using microbiological and histological methods, for the detection of shoulder and elbow periprosthetic joint infection (PJI). This is to establish the utility of pre-operative joint aspiration in the treatment pathway for shoulder and elbow PJI.
