Brief Summary
This study follows patients with infections after a joint replacement over time. During follow-up, treatment outcomes are carefully measured to determine whether the infection can be cured. In addition, factors that may change infection cure rates are examined, including the patient's overall health, the type of bacteria causing the infection, and the surgical and antibiotic treatments used. The goal is to understand what leads to more frequent cure and to improve future care.

Outcome Measures
Primary Outcomes (1)
Rate of infection failure
Rate of incident periprosthetic joint infection (according to European Bone \& Joint Infection Society criteria) or infection-related death. Types of failure include i) persistent or recurrent PJI with the same pathogen or no detected pathogen (i.e., treatment failure) and ii) a new infection caused by a pathogen different from the index episode.
Up to 5 years. The outcome will be evaluated during the period from enrollment until the date of last clinical visit, adminstrative censoring, lost to follow-up, death; whichever occurs first.
Secondary Outcomes (8)
Mean of range of motion measurement (hip)
Up to 5 years. The outcome will be evaluated during the period from enrollment until the date of last clinical visit, adminstrative censoring, lost to follow-up, death; whichever occurs first.
Mean of range of motion measurement (knee)
Up to 5 years. The outcome will be evaluated during the period from enrollment until the date of last clinical visit, adminstrative censoring, lost to follow-up, death; whichever occurs first.
Percent using any analgesics
Up to 5 years. The outcome will be evaluated during the period from enrollment until the date of last clinical visit, adminstrative censoring, lost to follow-up, death; whichever occurs first.
Percent using walking aids (for lower extremity)
Up to 5 years. The outcome will be evaluated during the period from enrollment until the date of last clinical visit, adminstrative censoring, lost to follow-up, death; whichever occurs first.
Mean of EuroQol five-dimensional questionnaire score
Up to 5 years. The outcome will be evaluated during the period from enrollment until the date of last clinical visit, adminstrative censoring, lost to follow-up, death; whichever occurs first.
- +3 more secondary outcomes
Interventions
Participants who undergo revision surgery of a prosthetic hip, knee, shoulder, ankle, or elbow joint for suspected periprosthetic joint infection. A patient may contribute one or more episodes, which are defined as a condition leading to revision surgery for a suspected or confirmed periprosthetic joint infection.
Eligibility Criteria
Participants who undergo revision surgery of a prosthetic hip, knee, shoulder, ankle, or elbow joint for suspected periprosthetic joint infection.
You may qualify if:
- ≥18 years of age
- Revision surgery of any large prosthetic joint (i.e., hip, knee, shoulder, ankle, or elbow) performed for a suspected or confirmed periprosthetic joint infections at any of the participating study centres. This includes patients who were previously treated at another hospital and referred to a participating study centre if data on a transferred patient from the previous institution are available, complete, and archived in the institutional patient information system, and the patient underwent at least one surgery at a participating institution.
- Obtained written informed consent
- Periprosthetic joint infections diagnosis likely or confirmed according to European Bone and Joint Infection Society criteria
You may not qualify if:
- Documented objection to subsequent use of personal health data
- Patient follow-up outside of Switzerland
- Diagnosis "periprosthetic joint infections unlikely" according to European Bone and Joint Infection Society criteria
