45 cases of anterior cruciate ligament rupture were evaluated on anteromedial rotatory instability (AMRI) and the effect of anterior cruciate ligament reconstruction, 8 were acute and others were old injuries. The incidence of AMRI was 69% (31 cases). 32 cases had medial meniscus tears and AMRI was severe in the cases of peripheral tears. The grade three ruptures of the medial collateral ligament was seen in two cases and in them AMRI was severe. All cases underwent reconstruction of anterior cruciate ligament with Leeds-Keio artificial ligament by the arthroscopic method. Medial meniscus tears were treated with the meniscal suture in 14 cases, subtotal meniscectomy in 8 cases and the partial meniscectomy in 10 cases. Medial collateral ligament ruptures were reconstructed in the cases of more than grade three. The results of each operative method were successful, and AMRI was noted in 4 cases postoperatively. But in these cases there were no disability related to AMRI.
