📌 Polyethylene Wear-Induced Synovitis and Osteolysis
- Polyethylene wear-induced synovitis and osteolysis are significant complications that can occur following joint replacement surgery.
✅ Polyethylene Wear-Induced Synovitis
- Frond-like synovial proliferation
- Dense synovial proliferation
- Debris with low-to-intermediate signal intensity
- Variable amounts of joint fluid and distention
✅ Polyethylene Wear-Induced Osteolysis
- Geographic pattern
- Particulate debris with intermediate signal intensity
- Replacement of normal periprosthetic trabecular bone and marrow fat
✅ Complications of Polyethylene Wear
- Bone Erosion: Occurs with increasing burden of intracapsular synovial proliferation and debris
- Neurovascular Compression: Formation of polyethylene granulomas and Focal expansion of the joint capsule
- Diagnostic Value: Sharp contrast resolution for accurate diagnosis and Allows segmentational quantitative volumetry for longitudinal monitoring
