With the increasing number of primary ACL reconstructions, revision surgery has become more frequent. Despite arthroscopic technique and treatment advancements, the current methods of reconstruction are far from perfect that a significant number of patients have an unsatisfactory. This article discusses the multiple mechanisms of failure of primary intra-articular ACL reconstruction and provides the orthopaedic surgeon with a systematic approach to the evaluation and treatment of failed ACL reconstructions.

The complication caused by a bioabsorbable interference screw composed of Poly-L-Lactic-Acid is rare after anterior cruciate ligament (ACL) reconstruction. We reported a case of a pretibial ganglion at the orifice of the tibial tunnel where the graft tendon had been fixed with a bioabsorbable interference screw $(Bioscrew^{\circledR})$ for ACL reconstruction using autogenous hamstring tendon. The patient was underwent ganglion excision and interference screw removal.

The mechanical study on the anterior and posterior cruciate ligament(ACL, PCL) is of importance because the recent increase of outdoor and indoor activities is directly related to causing sport injuries on the knee joints. Constitutive models for many biological tissues have been known as hyperelasticitic models. The elastic behavior of ACL and PCL may be described by the free energy function which accounts for the matrix and the collagen fibers. This paper addresses a comparison of different types of the free energy function to the existing results.

Localized form of tenosynovial giant cell tumor rarely affects the knee joint, only a few cases can be found in the literatures and there is no case report of the giant cell tumor arising from the posterior cruciate ligament in Korea. We experienced two cases of giant cell tumor arising from the posterior cruciate ligament, they were excised arthroscopically and pathologically confirmed. So we report these cases with a review of the literatures.

본 논문에서는 연구실에서 만든 음성인식기와 합성기를 이용하여 십자말 게임을 구현하였다. 십자말 게임에는 고사성어 600개 정도의 단어가 사용되었으며, 다른 영역별 사전을 추가 할 수 있도록 만들어졌다. 구현된 게임은 시작, 진행 등의 모든 과정이 음성으로 동작하며, 부과적인 정보는 음성 합성(TTS)에 의해 이루어진다. 십자말 게임에 사용되는 단어의 배열은 매번 랜덤하게 선택되도록 구성되며, 음성 인식기는 VCCV (Vowel + Consonant + Consonant + Vowel) 기반의 화자독립으로 구현되었다. 선택된 문제에 대한 설명은 텍스트로 보여주면서, 동시에 TTS 시스템에 의해 음성으로 출력된다.
