5. The knee feels unstable
Knee instability, also described as the knee “giving out” can be caused by many things including arthritis, patellar instability, or a meniscus tear. However, the one accompanying a popping sound and chilling pain is proof of an ACL tear. This means that the knee is compromised and would require immediate medical attention. An unstable knee is unlikely to support weight or bend and stretch effortlessly.
Treating an unstable knee depends on the severity of the ACL tear. A mild ACL injury resulting in knee instability can cure with enough rest, icing, and elevation of the knee to deal with swelling and pain. The victim can also wear a knee brace to help support the knee while it heals. From there, a series of physical therapies become essential in improving the knee’s strength and mobility. In a few weeks, the victim should be recuperating just fine.
