Inability to Bear Body Weight
Another symptom is the knee’s inability to bear the weight of your body. The swelling and the pain may be severe to the extent that you find it extremely difficult to even walk or stand without assistance from someone or a walking sticks.
Bruising Around the Knee
There may also be bruising all over the knee area. This bruising may be due to the contact of the knee to a hard surface right before the impact that caused the tear, and would require treatment.
Conclusion
Despite the fact that ACL tears are quite common, if not handled properly, it can worsen and cause a lot of pain. It is therefore very important to apply first-aid treatment at the moment of injury and go to a doctor for subsequent treatments to avoid pain and worsening of the symptoms.
