Abstract

Insights

Accurate pathogen identification is key for periprosthetic joint infection (PJI) two-stage revisions. This review evaluates diagnostic tests, guiding optimal re-implantation timing based on sensitivity and specificity.

Area of Science:

  • Orthopedic Surgery
  • Infectious Diseases
  • Diagnostic Imaging

Background:

  • Periprosthetic joint infection (PJI) management requires precise pathogen identification for successful two-stage revision surgeries.
  • Determining the optimal timing for re-implantation is critical to prevent reinfection and ensure prosthesis survival.

Purpose of the Study:

  • To systematically review literature on diagnostic methods for PJI pathogens.
  • To evaluate the sensitivity and specificity of microbiological, molecular, and nuclear imaging techniques.
  • To develop an algorithm for guiding re-implantation timing in two-stage PJI revisions.

Main Methods:

  • Systematic literature review of peer-reviewed papers on PJI diagnostic methods.
  • Analysis of microbiological and molecular diagnostic tests for pathogen identification.
  • Evaluation of nuclear imaging modalities for PJI detection, focusing on sensitivity and specificity.

Main Results:

  • Microbiological and molecular tests showed average sensitivities of 65.6% (cultural) to 86.9% (MicroDTTect) and specificities of 94.4% to 96%.
  • Nuclear imaging methods demonstrated high sensitivity (94% for bone scintigraphy, 100% for PET/CT) but lower specificity (69% and 62.5%, respectively).
  • MicroDTTect, molecular diagnosis, and specific nuclear imaging techniques offer valuable data for PJI diagnosis.

Conclusions:

  • Only select microbiological, molecular, and nuclear imaging tests are recommended for guiding re-implantation decisions in two-stage PJI revisions.
  • Test sensitivity and specificity are crucial factors in selecting appropriate diagnostic tools.
  • A refined diagnostic approach can optimize outcomes for patients undergoing two-stage revision for PJI.

Stages of Infection01:26

Stages of Infection

Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

Structural Joints: Fibrous Joints01:03

Structural Joints: Fibrous Joints

Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

Structural Joints: Cartilaginous Joints01:17

Structural Joints: Cartilaginous Joints

As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Joints01:26

Joints

Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
Fibrous Joints Are Immovable
The bones of a...

Introduction to Joints00:58

Introduction to Joints

The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Joints are the location where bones come together. Many joints allow for movement between the bones. At these joints, the articulating surfaces of the adjacent bones can move smoothly against each other. However, the bones of other joints may be joined by connective tissue or cartilage. These joints are designed for stability and provide little or no...
