Symptoms
When you injure your anterior cruciate ligament, you might hear a "popping" noise and you may feel your knee give out from under you. Other typical symptoms include:
- Pain with swelling. Within 24 hours, your knee will swell. If ignored, the swelling and pain may resolve on its own. However, if you attempt to return to sports, your knee will probably be unstable and you risk causing further damage to the cushioning cartilage (meniscus) of your knee.
- Loss of full range of motion
- Tenderness along the joint line
- Discomfort while walking
症狀
當前交叉韌帶受傷時，可能會聽到“砰”的聲音，並且會感覺到膝的跌落感。 其他典型症狀包括：
- 脹痛。 在24小時內，膝蓋會腫脹，腫脹和疼痛一般會自行消失。 但是，如果嘗試重新參加運動，則膝關節可能會不穩定，並且有可能進一步對半月板造成損傷。
- 活動範圍的缺失
- 關節處的壓痛
- 行走時不適
Doctor Examination
Physical Examination and Patient History
During your first visit, your doctor will talk to you about your symptoms and medical history.
During the physical examination, your doctor will check all the structures of your injured knee, and compare them to your non-injured knee. Most ligament injuries can be diagnosed with a thorough physical examination of the knee.
醫生檢查
體格檢查及病史
第一次就診時，醫生詢問症狀和病史。
在體檢時，醫生會檢查受傷膝關節的所有結構，並與沒有受傷的膝關節進行比較。大多數韌帶損傷可以通過對膝關節進行全面的檢查來診斷。
maging Tests
Other tests which may help your doctor confirm your diagnosis include:
X-rays. Although they will not show any injury to your anterior cruciate ligament, x-rays can show whether the injury is associated with a broken bone.
Magnetic resonance imaging (MRI) scan. This study creates better images of soft tissues like the anterior cruciate ligament. However, an MRI is usually not required to make the diagnosis of a torn ACL.
影像檢查
其他可能有助於醫生確診的檢查包括：
X光片。儘管它們不會顯示前交叉韌帶的損傷，但X射線可以顯示該損傷是否與骨折有關。
磁共振成像（MRI）掃描。 這項檢查能更好的顯示軟組織圖像，如前交叉韌帶。 但是，通常不需要MRI即可診斷ACL的撕裂。
