Summary
Revision total knee arthroplasty (TKA) can cause snapping due to the iliotibial band (ITB) adhering to the femoral component. Fractional lengthening of the ITB effectively resolved this issue, preventing further surgical intervention.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Revision total knee arthroplasty (TKA) cases are rising globally.
- Postoperative complications in TKA require careful management and understanding.
Purpose of the Study:
- To present a case of snapping phenomenon following revision TKA.
- To identify the cause of the snapping and its resolution.
Main Methods:
- Surgical observation during revision TKA.
- Identification of iliotibial band (ITB) impingement.
- Intervention via fractional lengthening of the ITB.
Main Results:
- Snapping was caused by the ITB adhering to the lateral femoral component.
- Fractional ITB lengthening successfully eliminated the snapping phenomenon.
Conclusions:
- The ITB impinging on the femoral component is a potential cause of snapping after revision TKA.
- Intraoperative identification and fractional lengthening of the ITB can resolve this complication, avoiding secondary procedures.
