Knee ligaments play a critical role in maintaining joint stability and preventing abnormal bone movements. When these ligaments are injured, the level of damage will determine the appropriate treatment. There are three levels of knee ligament injuries: grade one where the ligaments are stretched but still able to keep the knee stable, grade two with a partial tear causing joint looseness, and grade three with complete or partial rupture combined with other injuries.
For minor injuries, conservative treatments such as splinting and RICE therapy (rest, ice, compression, elevation) may be sufficient to allow the ligament to heal on its own. However, surgery is typically recommended for more severe injuries. The surgery usually involves reconstructing the ligament using either autologous tendons or artificial materials using minimally invasive techniques to reduce the risk of infection.
After surgery, patients undergo rehabilitation that includes personalized exercises aimed at improving ligament function, restoring muscle strength and preventing complications such as muscle atrophy. Rehabilitation also focuses on protecting grafts as they transform into true ligaments. Depending on the type of surgery and individual progress, patients can usually resume walking, running, and playing sports within a few months to a year after surgery.
It is important to seek medical attention promptly when indicated to prevent complications such as joint instability, cartilage degeneration and osteoarthritis. Timely treatment can help avoid disability and the need for artificial joint replacement in severe cases.
