Meniscus Tear
了解 Knee Magnetic Resonance Imaging 影像中的 Meniscus Tear，明确其含义与下一步措施。
影像表现
Magnetic Resonance Imaging FindingLinear high-signal cleft reaching articular surface within meniscus; displaced fragments may form a bucket-handle.
临床意义
Common cause of knee pain and locking; management depends on tear type and symptoms.
What is a Meniscus Tear?
Cartilage injury to the medial or lateral meniscus. MRI defines tear pattern and stability.
Imaging Appearance
- High-signal line contacting articular surface
- Horizontal, radial, complex, or bucket-handle patterns
- Parameniscal cysts may accompany horizontal tears
Clinical Significance
- Unstable tears can lock the knee
- Degenerative tears may respond to therapy; traumatic tears in young often repaired
Symptoms
- Joint line pain, catching, locking, effusion
Diagnosis
- MRI knee
- Clinical tests: McMurray, Thessaly
Treatment
- Physical therapy, NSAIDs
- Arthroscopic repair or partial meniscectomy for symptomatic tears
Prognosis
- Better with repair in vascular zones; degeneration risk after meniscectomy
What Should You Do?
- Reduce high-impact activity until evaluated.
- Start quad/hamstring strengthening under guidance.
- Consider surgery if locking or persistent pain.
