Which is more serious, a meniscal injury or a ligament injury, depends at this point on the clinical symptoms caused by the injury to each structure and the stability of the knee joint. If the meniscus injury or ligament injury is mild and there is only clinical pain in the knee joint without joint instability or symptoms of popping or interlocking of the knee joint, it is not very serious and only requires conservative treatment, requiring 4-6 weeks of immobilization of the knee joint with a brace or cast and gradual functional exercises. If the meniscus or ligament injury causes severe knee pain, joint popping, interlocking, or significant joint instability due to ligament injury, it is more serious and often requires surgery to suture the meniscus or remove the meniscus, as well as suture repair or ligament reconstruction to restore the integrity of the ligament. This will restore the integrity of the ligaments and allow the knee to function normally.
