Knee ligament injuries first require us to determine which ligament is damaged. The injury mechanism can help determine which ligament is affected, such as an inversion or eversion injury of the knee, which could cause damage to the medial or lateral collateral ligaments of the knee. Sometimes, knee flexion and rotation injuries may damage the cruciate ligaments of the knee. Once the specific ligament is identified, the extent of the injury must be determined. If the injury is minor, such as a contusion, rest may allow the ligament to gradually recover. If there is a tear, but the knee joint is still stable, conservative treatment can be pursued; however, if there is a tear and the knee joint is unstable, or if the ligament is completely ruptured, we recommend surgical repair to restore the stability of the knee joint.

How long will it take for a ligament sprain and soft tissue injury to fully heal?

Ligament strains or soft tissue injuries are common in everyday life, and they also typically require grading. Some minor ligament strains or soft tissue injuries generally heal after about three weeks of rest and immobilization. If a ligament strain or soft tissue injury is very severe, such as when the ligament has reached the level of tearing, or if there is significant bleeding, edema, and swelling at the time of the injury, this indicates a very serious soft tissue injury. In such cases, the duration of immobilization might be much longer, possibly around six weeks. The recovery time for such soft tissue injuries or ligament strains can also be very lengthy, sometimes extending up to three months or even six months.

How to treat patellar ligament injury?

First, it is necessary to qualitatively assess the injury of the patellar ligament, determining whether it is a partial or complete rupture, whether it is a simple rupture, or a compound rupture, the latter involving other injuries such as fractures or joint dislocations. The treatment of patellar ligament injuries, like other tendon injuries, follows the principle of "three earlies": early diagnosis, early treatment, and early rehabilitation. Early diagnosis has been mentioned before. Early treatment means that if surgery is needed, it should be conducted as soon as possible, as earlier surgeries often result in better postoperative recoveries. If surgery is not required, an immediate fixation with a cast or brace should be applied to keep the knee joint in an extended position, and this fixation should be maintained for three to four weeks. The third step is early rehabilitation. As the knee joint is immobilized during the fixation period, and pain and swelling starts to decrease, early functional exercises should be initiated, focusing on distal joint movement and muscular isotonic exercises, but avoiding flexion and extension movements of the knee joint. Early rehabilitation primarily aims to prevent muscle atrophy, prevent joint adhesion, and promote recovery from the condition.

Can I drink yogurt with a ligament injury?

After a ligament injury, the treatment varies depending on the severity of the injury. However, in the acute phase, the main treatments include immobilization and elevation of the affected limb. As for what medications to take or what foods to eat to promote healing of a ligament injury, currently, there are no foods found to have a significant promoting effect on ligament recovery, nor are there common everyday foods that hinder ligament repair. Of course, we still recommend avoiding spicy foods. Therefore, after a ligament injury, it is okay to drink yogurt. There are no contraindications with yogurt, nor is there evidence that yogurt has any beneficial effects on ligament repair.

Post-symptoms of knee ligament injury

The knee joint has four crucial ligaments: the anterior and posterior cruciate ligaments, and the medial and lateral collateral ligaments. They act like four pillars, firmly anchoring the knee joint in a very stable and normal position. If any of these ligaments rupture, this balance is disrupted, causing the knee to move abnormally in a certain direction, leading to increased local wear and tear or compensatory wear in other parts. Therefore, if ligament damage is not repaired, and the balance is disrupted, it can lead to many complications or sequelae. The first is traumatic arthritis. The second is patellar chondromalacia. The third is meniscus damage. The fourth is damage to other ligaments, or even rupture. The fifth is knee arthritis, also known as OA, or degenerative changes. The sixth is knee effusion and synovitis. Thus, the sequelae of knee ligament injuries are numerous and troublesome.
