Abstract
The opinion vary as to whether conservative treatment or operative treatment should be taken for medial collateral ligament (MCL) injuries of the knee. In the present study we discussed the absolute indication for operation for MCL of the knee. The subjects were 32 cases treated in our hospital over the past 9 years. All cases were operated on according to the operative indication on our hospital's assumption and obtained successful results regardless of the injured lesion.
In the case of athletes' MCL injurys of the knee, only valgus stress affected the knee 2-dimensionally in a few cases, while not only valgus stress but also external rotation with the knee-semiflexion 3-demensionally in many cases. Therefore it is problematic to decide which therapy to use easily based on the severity of valgus stress only. In order to have athletes return, we suppose it is necessary to diagnose generally and correctly using arthroscope or other means. The problem is whether or not we can identify correctly the injured lesion preoperatively.
