Check for warning signs of a torn anterior cruciate ligament (ACL). Don't ignore it until you can't walk.
Symptoms indicating a "torn anterior cruciate ligament".
In the early stages, many patients can still walk normally without any noticeable severe symptoms, so they often become complacent, thinking it's just minor pain. When the anterior cruciate ligament (ACL) begins to damage, the body may send subtle warning signals, but not all symptoms come suddenly. Sometimes it's just a slight feeling of instability when climbing stairs or a sharp pain when turning. One of the most common symptoms is a "pop" or "snap" sound when twisting occurs in the knee, a sound often accompanied by a jolt.
This may then be followed by swelling of the knee joint in the first few hours, making it immediately noticeable that the knee is not the same as before. While some people may have no noticeable symptoms until they begin to feel that their knee is unstable, as if it's about to collapse with each step, or feel unusually tired after walking for a few minutes.
In some patients, the pain may not be severe, but rather a feeling of stiffness or tightness when moving, a sensation as if the knee is "not in place" when moving quickly, such as running or stopping suddenly, or when going up or down stairs, requiring more support with the hands, or reluctance to put weight on the injured leg.
What distinguishes an anterior cruciate ligament (ACL) tear from other injuries is the feeling of knee instability, as if the leg can no longer bear weight or be controlled as before. If left untreated, the knee joint's structures can become unbalanced, leading to premature osteoarthritis. Furthermore, a loose and unstable knee is susceptible to recurrent injuries such as meniscus tears or articular cartilage erosion.
As these problems accumulate, some patients may develop chronic pain, difficulty walking, and eventually need a cane or wheelchair to assist with movement.
Behaviors that increase risk.
These symptoms often result from seemingly harmless daily habits that unknowingly accumulate pressure or twisting force on the knee joint. Examples include sudden changes in direction while walking or running, sudden stops, prolonged squatting or sitting cross-legged, repeatedly climbing stairs, or wearing ill-fitting shoes.
When these behaviors are repeated without strengthening the muscles around the knee, they can eventually accelerate the tearing of the anterior cruciate ligament (ACL).
Prevention is better than cure: Don't wait until your knees are out of balance.
While it's impossible to prevent injuries 100%, we can reduce the risk by strengthening the muscles around the knee, practicing safe movement techniques, avoiding sudden jerks, and choosing appropriate footwear for the activity.
If a patient notices or experiences symptoms indicating an anterior cruciate ligament (ACL) tear, they should seek immediate diagnosis and treatment to prevent further injury. At S Hospital, we have a team of experienced doctors who treat patients according to the correct cause. With state-of-the-art technology and equipment, we offer minimally invasive arthroscopic surgery to repair torn ligaments, a key aspect of our treatment that helps patients regain movement and return to normal life more quickly.
