| Cause: When the shin bone is pressed outwards in relation to the thigh bone the inner side-ligament is stretched. If the load becomes sufficiently powerful (as is the case when the load is sudden, so that the thigh muscles do not have time to tighten and stabilize the joint) the ligament can rupture.
Symptoms: Sudden pain on the inside of the knee. Occasionally a snap is felt when the ligament ruptures. In severe cases the athlete complains about a sense of looseness in the knee.

Examination: If a total or partial rupture of the ligaments in the knee is suspected, you should seek medical attention for a diagnosis. An x-ray examination is recommended as many ligament injuries in children and adolescents can be accompanied by damage to the bone at the point of attachment of the ligaments (article). The doctor can perform various knee tests (internal side-instability-test), to examine the stability of the knee. If the knee is stable the injury is called a “sprain” of the inner side-ligament. If the knee is loose the injury is called a “rupture” of the ligament. The diagnosis is usually made from a normal medical examination. If there are any doubts surrounding the diagnosis, an ultrasound scan can be performed which will reveal the rupture and the bleeding along the ligaments (Ultrasonic image) .
Treatment: The treatment of a partial or total rupture of the inner side-ligament involves relief and rehabilitation. If the knee is markedly loose, you can, for a short period, use a support splint (Don Joy). Surgical treatment previously considered has today largely been abandoned in uncomplicated ruptures of the inner side-ligament (article-1)(article-2). (However if the rupture of the inner side-ligament is combined with other ligament ruptures, many would recommend surgery).
Bandage: Hinge bandages can be used initially (Don Joy). Tape treatment of ligament ruptures in the knee have no sure effect.
Complications: If smooth progress is not achieved, it should be considered whether the diagnosis is correct or whether complications have arisen. Supplementary examinations (X-ray, ultrasound, MR scan or arthroscopy) will often be required. The following should be considered:
Special: Since there is a risk that the injury can cause permanent disability, the injury should be reported to your insurance company.
