In a young patient like you a complex lateral meniscus tear can be a significant pain and instability source, especially if you have locking, catching, swelling after activity, or knee giving-way. Low-grade ACL/PCL sprains usually heal without surgery, but the meniscus tear does not always heal on its own, particularly when it is complex. Management depends on symptoms—if pain, swelling, or mechanical symptoms persist despite rest and conservative care, arthroscopic evaluation and treatment may be required. A detailed clinical examination will help decide whether surgery is needed or if careful non-operative management is still reasonable.
