After ligament injuries, the common imaging examinations usually include standard X-rays, CT scans, and MRI. X-rays are mainly used to observe the overall shape of the bones and the alignment, CT scans are primarily for examining the condition of the bones at the injury site, especially the form of the bones, while MRI mainly uses the hydrogen atom content, or water content, to determine if there is an injury. When a ligament is injured, there won't be bleeding, which leads to an increase in water content; thus, an MRI can easily reveal the increased water content and help diagnose the injury. Therefore, the best method to diagnose ligament injuries is through MRI. Of course, X-rays are used for general overview and alignment, which are the most basic and common examinations, followed by CT scans. Generally, CT scans are not necessary unless there is a special circumstance.

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.)

How to recover from ligament damage

For patients with ligament injuries, it is first necessary to determine the severity of the ligament damage in order to establish an active treatment plan to promote rapid repair of the ligament. If the ligament injury is relatively mild and joint stability is good, it is entirely possible for such patients to choose active conservative treatment. It is necessary to strictly use plaster casts or supportive external fixation. During this period, treatment can include oral non-steroidal anti-inflammatory and pain-relieving medication as well as drugs that promote blood circulation and disperse blood stasis. For those with more severe ligament injuries and poor joint stability, it becomes necessary to actively proceed with surgical treatment, which might involve repairing or reconstructing the damaged ligament. (Please use medication under the guidance of a doctor.)

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.

How to operate on ligament damage

Ligament injuries that affect joint stability require surgery, and different locations necessitate different surgical methods. Generally, for ligaments within a joint, such as the anterior cruciate ligament or the posterior cruciate ligament of the knee, reconstruction is performed using either autografts, allografts, or synthetic tendons to replace the original damaged ligaments. For ligaments outside of a joint, such as the medial collateral ligament, lateral collateral ligament of the knee, or the anterior talofibular ligament of the ankle, if the joint stability is compromised, suturing is generally performed during the acute phase. For chronic, long-standing injuries that affect joint stability, reconstruction is usually necessary, also using autografts, allografts, or synthetic tendons to substitute their function.

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.
