Summary
Total knee replacement surgery is increasingly common, offering an alternative to arthrodesis. Radiologists evaluate alignment and diagnose complications like loosening or infection using X-rays and arthrography.
Area of Science:
- Orthopedic surgery
- Medical imaging
- Biomedical engineering
Background:
- Total knee replacement (TKR) is a successful surgical option.
- Advances in surgery and bioengineering enhance TKR viability.
- More patients are offered TKR as an alternative to arthrodesis.
Purpose of the Study:
- To outline the radiologic evaluation of total knee replacement.
- To discuss the diagnosis of postoperative complications.
- To illustrate radiographic findings associated with TKR.
Main Methods:
- Plain film radiography for assessing alignment and complications.
- Arthrography as an additional imaging technique.
- Review of radiographic features of common TKR issues.
Main Results:
- Radiographic evaluation is crucial for TKR success.
- Common complications include loosening, instability, and infection.
- Plain films and arthrography effectively identify these issues.
Conclusions:
- Total knee replacement is a growing procedure.
- Radiologic consultation is essential for postoperative management.
- Imaging techniques aid in diagnosing TKR complications and ensuring proper alignment.
