# Risk of Periprosthetic Joint Infection after Intra-Articular Injection: Any Difference among Shoulder, Knee and Hip?

## TL;DR

This paper investigates whether the risk of joint infection after intra-articular injections differs among shoulder, knee, and hip joints.

## Contribution

The study explores correlations between injection type, dosage frequency, and timing with infection risk in future prosthetic surgery.

## Key findings

- The risk of periprosthetic joint infection is a significant concern following intra-articular injections.
- Literature review suggests a need to correlate injection type and timing with infection rates.
- Conservative treatment strategies may delay surgery but carry infection risks.

## Abstract

Osteoarthritis is a degenerative joint disease caused by the wear and tear of joint cartilage. The definitive and resolving treatment is prosthetic replacement of the articular surface, the demand of which is on the rise for patients with mild to moderate severity. However, a conservative strategy may be considered that aims to reduce and contain pain symptoms by postponing surgical treatment in the case of worsening that can no longer be otherwise controlled. Intra-articular infiltrations, like other therapeutic strategies, are not without complications, and among these the most feared is joint infection, especially in anticipation of future prosthetic replacement. Is important to avoid periprosthetic joint infections because they represent one of the third most common reasons for revision surgery. Using cases found in the literature, the aim of this article is to determine if there is a real correlation between the type of injections, the number of doses injected and the time between infiltrations and the surgical procedure.
