The individual prognosis of an external ligament extension is essentially dependent on the involvement of other structures of the knee as well as individual factors of the affected person. In general, the prognosis of an extension of the external ligament can be considered very good if the injury is treated consistently. Complications are rare and, as a rule, complete restoration of the function and stability of the knee joint can be achieved. It should be noted, however, that the prognosis is significantly worse in the case of involvement of bony structures and serious injuries in the context of major accidents.
Since sports injuries are known to be the main cause of outer ligament stretching, special caution is recommended, especially for sports that are suspected of causing this injury. A general recommendation, which is a precautionary measure for the development of the outer ligament strain, cannot be recommended.
