Periprosthetic osteolysis: a narrative review

Area of Science:

• Biomaterials Science
• Immunology
• Orthopedic Surgery

Background:

• Periprosthetic osteolysis is a major cause of prosthetic joint failure.
• It involves mechanical and biological factors leading to implant loosening.
• Wear debris and cell-particle interactions are key elements in the periprosthetic microenvironment.

Purpose of the Study:

• To review recent studies on the pathogenesis of periprosthetic osteolysis.
• To summarize biological and mechanical factors contributing to osteolysis.
• To explore current pharmacological treatments for failing implants.

Main Methods:

• Narrative review of existing literature.
• Analysis of studies on wear debris and cell-particle interactions.
• Examination of factors like micromotion, implant position, and joint fluid pressure.

Main Results:

• Osteolysis pathogenesis is driven by a complex interplay of factors.
• Immune response in periprosthetic tissue is a critical component.
• Wear debris and cellular interactions significantly contribute to aseptic loosening.

Conclusions:

• Understanding the multifactorial nature of osteolysis is crucial for improving prosthetic joint longevity.
• Pharmacological interventions show promise in managing or reversing osteolysis.
• Further research is needed to develop effective strategies to "rescue" failing implants.
