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 supplements are good for ligament injuries?

Patients with ligament injuries are advised to consume more foods containing high-quality protein, such as beef, eggs, and milk. However, it is not recommended to eat high-calorie, high-nutrient foods, such as sea cucumber and abalone. Ligaments are important structures that connect two bones at the joint. Once a ligament is injured, it can only recover under strict rest, which may involve immobilization with plaster casts and bed rest. After a ligament rupture, a great amount of energy is consumed during the healing process. It is crucial to balance meat and vegetables in the diet and maintain nutritional balance. It is suggested to appropriately increase the intake of high-quality protein foods, such as beef, eggs, and milk, but it is not advised to consume high-calorie, high-nutrient foods, like sea cucumber and abalone.

What should I do if I have a knee ligament injury?

Ligament injuries in the knee are commonly seen in two areas: the first is the anterior cruciate ligament (ACL) injury, and the second is the medial collateral ligament (MCL) injury. The treatment for these two ligament injuries is the same; for instance, in cases of just a simple ligament tear or partial tear, it only requires the use of a plaster cast for external fixation, and immobilization for three to four weeks can achieve recovery. If there is a complete tear, surgery might be needed. There are two types of surgeries: the first one involves direct repair of the ligament, the second involves using autologous tendons to reconstruct the ligament, restoring the stability of the entire knee joint. To determine whether you have a tear, complete tear, or partial tear, it is necessary to undergo an MRI of the knee to confirm.

Symptoms of fibular ligament injury

The symptoms of fibular ligament damage include, first, pain, especially noticeable tenderness or pain around the fibula when bearing weight, which can further affect weight-bearing walking. Second, swelling can occur, particularly after prolonged weight-bearing walking, leading to localized swelling that gradually subsides with rest. Third, joint instability can also occur as the stability of the entire joint deteriorates after ligament damage, resulting in instability during prolonged weight-bearing activities, and in severe cases, affecting joint mobility and damaging the joint cartilage.

Can ligament injuries heal by themselves?

Whether ligament injury can be healed depends on the severity of the injury. Generally, there are four types of ligament injuries. The mildest is a sprain, which is when some fibers of the ligament are torn. The second type is a partial tear of the ligament, the third type is a complete tear of the ligament, and the fourth type is a combined injury, which includes damage to other structures in addition to the ligament injury. If the ligament injury is just a sprain, it can generally heal within two to three weeks with immobilization. However, partial ligament tears that are more severe may require surgical intervention. If the partial ligament injury is not severe and does not affect stability, it can also heal with about three to six weeks of immobilization. However, complete ligament tears or combined injuries often require surgery for suturing or reconstruction in order to heal.
