Purpose: we would like to suggest the proper surgical methods according to the severity of instability by analyzing the results. Materials and Methods: Between January 1998 and August 2002, eighty five patients have been operated on because of posterolateral rotatory instability (PLRI). The materials were included the patients who had followed-ups for over 2 years in sixty one patients and the patient's assessments were done by clinical score (OAK, IKDC) and posterolateral drawer and dial test. Results: Through our results, the fibular tunnel turned out to be superior compared to the tibia tunnel method in rotational stability. Hughston-Jacobson methods and biceps tenodesis showed poor results. Fibula head tunnel was superior to tibia tunnel in rotational stabiliaty Conclusion: The surgical technique that passes the modified posterolateral corner sling through the fibula head tunnel may provide good clinical results in grade II PLRI. It is necessary to reconstruct both tibia and fibula tunnel in grade III PLRI. When there is combined varus instability, a positive result may be obtained if an additional LCL reconstruction is performed.

Purpose: Several methods of anatomical reconstruction for chronic lateral ankle instability has been reported to avoid the problems of nonanatomical reconstruction. Precise reconstruction of the normal anatomy is essential to the restoration of normal joint mechanics and stability. The problem with anatomical reconstruction is that it is very difficult to reconstruct the normal anatomic course of the ligaments. We thought making one tunnel at the fibular attachment of anterior talofibular ligament and calcaneofibular ligament was more anatomical than making separate tunnels for each ligaments because the two ligaments are contiguous. In this article, the basis of anatomical reconstruction of the lateral ankle ligaments was reviewed and a technique of reconstruction using semitendinosus was introduced.

Purpose: The purpose of this study is to evaluate the clinical results of posterior cruciate ligament (PCL) and posterolateral structure (PLS) reconstruction using bilateral hamstring tendon autografts. Materials and Methods: From October 2002 to March 2004, ten patients were received PCL and PLS reconstruction simultaneously using bilateral hamstring autografts. PCL was reconstructed using ipsilateral hamstring tendon and fixed with cross pins and Intrafix (Mitek, Norwood, MA). PLS was reconstructed using contralateral hamstring tendon. The mean follow up was 17 months. Clinical assessments consisted of Lysholm knee scores, International Knee Documentation Committee (IKDC) evaluation form and posterior stress radiographs. External rotation of tibia was evaluated at $30^{\circ}\;and\;90^{\circ}$ knee flexion using Noyes and Barber-Westin's classification. Contralateral harvest site morbity was evaluated using IKDC evaluation form and flexion power of the knee. Results: Mean posterior displacement of tibia using stress radiographs was improved from 13.3 mm to 3.7 mm. In tibial external rotation evaluation, 7 patients were functional, 2 patients were partially functional and one failure. The average Lysholm knee score improved from 54 preoperatively to 86 postoperatively. At the final IKDC evaluation, 8 patients were graded as nearly normal, 2 were graded as abnormal. In contralateral harvest site morbidity evaluation, 2 patients complained of numbness around the wound but negligible. Conclusion: PCL and PLS reconstruction using bilateral hamstring autografts was considered as a good treatment method with minimal contralateral harvest site morbidity.
