Prosthetic joints

Definition

Prosthetic joints are artificial devices surgically implanted to replace damaged or diseased joints, commonly in the hip or knee. They can be susceptible to bacterial infections that can complicate the circulatory and lymphatic systems.

5 Must Know Facts For Your Next Test

1. Bacterial infections of prosthetic joints often involve biofilm formation, making them difficult to treat.
2. Staphylococcus aureus and Staphylococcus epidermidis are common pathogens responsible for these infections.
3. Early diagnosis of prosthetic joint infection is crucial and typically involves synovial fluid analysis and imaging studies.
4. Treatment usually requires a combination of surgical intervention and prolonged antibiotic therapy.
5. Prosthetic joint infections can lead to severe complications, including sepsis and chronic pain.
