[Diagnosis and treatment of acute medial collateral ligament ruptures of the knee].
OBJECTIVE
To study the diagnosis and treatment of the acute medial collateral ligament ruptures of the knee.


METHODS
From August 1998 to August 2003, 87 cases of acute medial collateral ligament ruptures were examined with physical method and MR imaging. Out of them, 35 cases of I degree and II degree ruptures were treated with non-surgery and 52 cases of III degree ruptures were treated surgically. The torn medial collateral ligaments were mended, 21 of which were strengthened with the anterior partial gracilis muscle tendon after the arthroscopy.


RESULTS
In 35 cases of I and II degree ruptures, 32 were followed up 13 months on average. According to Lysholm scoring system, the clinical results were classified as excellent or good in 93.7% of the cases. In 52 cases of III degree ruptures, 50 were followed up 16 months on average. The excellent or good result was 90%.


CONCLUSIONS
For I and II degree ruptures, MR imaging is an important way to definitely diagnose medial collateral ligament ruptures. Abduction stress test of knee extension shows that the medial direct instability is a main way to definitely diagnose III degree ruptures. The results of conservative treatment of I degree and II degree ruptures are excellent. Surgical therapy are fit for the cases of III degree ruptures.
