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.
Aged: 18 years or older.
A participant is willing and able to give informed consent for participation in the study.
Patient undergoing revision shoulder or elbow arthroplasty surgery.

Refusal of consent.
Antibiotic treatment was not stopped 2 weeks before aspiration or biopsy.
