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.

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.

How to recover from collateral ligament injury of the knee joint

The knee joint has important ligaments on both the inner and outer sides, known as the medial collateral ligament and the lateral collateral ligament. In sports injuries, collateral ligament damage of the knee is very common. If there is an injury, the first step is to conduct a series of examinations to determine the stability of the knee joint. The damage to these ligaments can range from tears to complete ruptures. If there is only a contusion or a tear, the knee can recover its function through the use of supportive braces and the natural healing of the ligament. However, if the collateral ligament is completely ruptured, surgery is necessary for repair. The specific extent of the damage needs to be determined by MRI and physical examinations to decide the best treatment approach for the patient's recovery.

Symptoms of femoral head ligament injury

The clinical symptoms of a femoral head ligament injury mainly manifest as significant local pain. Severe cases may affect the patient's joint mobility and normal ability to move about, which are the clinical manifestations of a femoral head ligament injury. Usually, within a recent period, it is necessary to strictly rest in bed to protect the area, reducing local stimulation, which is the best condition for patient recovery. If the patient is not allergic to plasters, topical plasters that invigorate blood and dissolve stasis can be used, along with oral non-steroidal anti-inflammatory and pain-relieving drugs, and drugs that invigorate blood and dissolve stasis for treatment. After 48 hours post-injury, local heat application should be actively performed. Most patients will gradually recover through these active treatment methods. (The use of medications should be under the guidance of a professional doctor.)

What medicine is good for ligament injury?

Ligament injuries first require assessment of whether the damage is acute or chronic before considering medications. For acute ligament injuries, there are key principles to follow. First, the injured area must rest and the joint should no longer be active. Second, immediately apply cold compresses. The temperature of the ice-water mixture touching the skin should be between 4℃ to 10℃. Apply the cold compress for about 10 to 15 minutes, generally not exceeding 20 minutes. If there is severe swelling, you can continue to apply cold compresses two hours later. Then, elevate the patient's limb and apply compression bandaging to the injured site, which forms the treatment principles for acute ligament injuries. For chronic ligament injuries, different situations require different approaches. For ligament injuries that do not affect joint stability, some topical medications can be used. This can include traditional Chinese medicines or anti-inflammatory and analgesic patches, which mainly improve local blood circulation and reduce local chronic inflammation. (Please use medications under the guidance of a doctor.)

What should I do if the patellar ligament is injured?

Once a patellar ligament injury occurs, the first step is to immobilize the area; stop all activities to prevent further damage and secondary injuries. Secondly, apply ice. The initial ice application should last from half an hour to an hour, applied directly to the injured patellar ligament. Thirdly, bandage to immobilize the area, primarily using an elastic bandage and cotton padding to compress the knee joint. This can help stop bleeding and limit swelling. Fourth, elevate the injured limb to at least 30 degrees above the level of the heart. After these measures, it's necessary to go to the hospital for further examination including physical assessments by a doctor, X-rays, or an MRI to fully understand the extent of the ligament damage. If there is a partial tear of the ligament without complete discontinuity, conservative treatment such as casting or bracing can be effective, typically for three to four weeks. However, if the ligament is completely torn and surgery is clearly indicated, surgical treatment should be followed by the use of a brace for six weeks. Thus, proper early management of a patellar ligament injury is crucial, followed by hospital evaluation. Additionally, since patellar ligament injuries often coincide with fractures or damage to other structures such as the meniscus or cruciate ligaments, these factors cannot be overlooked.
