Good stability and complete range of motion should be the ultimate goal of a rehabilitation program after ACL reconstruction. In previous years. the rehabilitation of the ACL reconstructed knee focused on protecting the new ligament by blocking terminal knee extension, hut, despite good stability, this approach led to numerous postoperative complications. Nowadays, most of surgeons agree the accelerated rehabilitation program based on the concept of ligamentization and clinical experience. Accelerated rehabilitation program consists of maintain of full extension of the knee, early weight bearing and prompt recovery of ROM, and closed kinetic chain exercise. Meeting this goal requires effective communication between-members of the health care team-the physician, physical therapist, atheletic trainer, and the patient. We have to know the importance of rehabilitation, knowlege about the physical therapy, and to introduce for special physical therapist and equipment.

목적: 전방십자인대 재건술의 수가 증가하면서, 재건술의 실패로 인한 재재건술의 빈도 또한 증가하고 있다. 따라서 저자는 전방십자인대 재건술 후 발생한 이식건 실패의 원인 및 전방십자인대 재재건술 후의 임상적 결과를 분석하였다. 대상 및 방법: 1998년 2월부터 2010년 7월까지 전방십자인대 재건술 실패에 대하여 전방십자인대 재재건술을 시술받은 후 최소 12개월 이상 추시가 가능하였던 36예를 대상으로 하였다. 재건술 후 재재건술까지의 평균기간은 60(5~334)개월이었으며, 처음 전방십자인대 재건술을 시술 시 23예(63.9%)에서 동종 이식건을, 13예(36.1%)에서 자가 이식건을 사용하였다. 전방십자인대 재건술 실패의 주증상으로 불안정성이 가장 많았으며, 전방십자인대 재건술을 한번 시행 받았던 경우가 35예(97.5%), 두 번 시행 받았던 경우가 1예(2.5%)였다. 임상적 결과는 Lysholm 슬관절 점수, Tegner activity 점수를 이용하여 평가하였으며, 안정성은 Lachman 및 pivot shift 검사와 Telos device를 이용하여 평가하였다. 결과: 환자의 평균 추시 기간은 21(12~40)개월이었으며, 전방십자인대 재건술의 실패원인으로는 외상이 19예(52.8%)로 가장 많았고, 대퇴 터널의 부정위치가 13예(36.1%), 경골부 터널의 부정위치가 1예(2.8%), 골융합의 실패 3예(8.4%)로 나타났다. 전방십자인대 재재건술을 시행할 시 34예(94%)에서 동종이식건을, 2예(6%)에서 자가 이식건을 사용하였으며, 21예에서 반월상 연골판 손상이 동반되었다(내측 반월상 연골판 손상 14예, 외측 반월상 연골판 손상 7예). Lysholm 슬관절 점수는 술전 66.5점에서 술후 최종 추시시 92점으로 호전되었다(p<0.01). 환자의 대부분은 수술 결과에 만족(92%)하고 있었다. Tegner activity 점수는 술전 2.0점에서 술후 6.2점으로 호전되었다(p<0.01). Lachman 및 pivot shift 검사에서 33예, 30예가 Gr I 이하로 호전되었으며, Telos device를 이용한 안정성 검사에서는 양측 차이 정도는 술전 평균 15.5 mm에서 술후 최종 추시시 4.5 mm로 의미있게 호전되었다(p<0.01). 환자의 대부분은 수술 결과에 만족(92%)하고 있었다. 결론: 전방십자인대 재 재건술은 1년 이상 추시 결과 약간의 전방 불안정성이 존재하였으나, 임상적 결과 및 환자의 주관적 만족도에 있어서는 우수한 결과를 보였다.

Purpose : Today, it enjoys a sports and a leisure where the anterior cruciate ligament(ACL) injury patient increase. The knee joint is important means of human body movement and to do an important duty when it encounters ACL injuries of the knee joint and the many restriction follows in the life which is ordinary. When it is damaged ACL, it comes to determinate that ACL reconstruction and preservation treatment that the according to condition of ligament and knee joint. After ACL reconstruction, that is the fact which already becomes known the exercise treatment advances a recovery and to reduce a sequela. Methods : we researched the method of exercise treatment after anterior cruciate ligament reconstruction operation by journal of science direct and KISS in daecu university. Results : The representative exercise treatment is isometric exercise, isokinetic exercise isotonic exercise and complex exercise but what kind of exercise treatment most is effective, it revealed and support it was not. The method of exercise treatment is very various, so It causes a confusion made to the therapist and patients. So it executes once again it sought the kinetic therapeutic method which is efficient from this research and it tried to observe preceding research after ACL reconstruction. To operation a various the exercise treatments, operation only the treatment which is general compared to it was effective in muscular power and muscle functional improvement. But this like improve despite with the exercise treatment consequence which is continuous from research of most the pain leg compares to the health leg, it appeared the discrepancy which is a muscular power, a muscular endurance and a hypertrophy muscle etc, to the health leg or before operating 100% of muscular power to having gets the many therapy time was the recovery rate. Conclusion : Therefore after ACL reconstruction, it will become the many research continuously which is improve the muscle functional and ROM of the exercise treatment method and From therapeutic site of the patients it does to memorizes knowledge in advance about ACL injuries and the application the isokinetic treatment or exercise program are the set of necessary, frequency and amusement that considers complex what kind of therapeutic exercise becomes accomplished with the patient take care of attention.

Anterior cruciate ligament(ACL) injury of the knee is common and a serious ACL injury leads to ligament reconstruction surgery. Gait analysis is used to identify the result of surgery. The purpose of this study is to numerically evaluate and classify knee condition of patients through the chaos analysis. Experiments were carried out for 13 subjects (8 healthy subjects, 5 ACL deficient patients) walking on a treadmill. Sagittal kinematic data of the right lower extremity were collected by using a 3D motion analysis system. The recorded gait patterns were digitized and then coordinated by KWON3D. The largest Lyapunov exponent from the measured knee angular displacement time series was calculated to quantify local stability. It was found that the Lyapunov exponent becomes larger as the knee condition becomes worse. This study suggested a method of the severity of injury and the level of recovery. The proposed method discerns difference between healthy subjects and patients.

Purpose: To evaluate the knee joint after double-bundle anterior cruciate ligament (ACL) reconstruction with three-dimensional (3D) isotropic magnetic resonance (MR) image, and to directly compare the ACL graft findings on 3D MR with the clinical results. Materials and Methods: From January 2009 to December 2014, we retrospectively reviewed MRIs of 39 patients who had reconstructed ACL with double bundle technique. The subjects were examined using 3D isotropic proton-density sequence and routine two-dimensional (2D) sequence on 3.0T scanner. The MR images were qualitatively evaluated for the intraarticular curvature, graft tear, bony impingement, intraosseous tunnel cyst, and synovitis of anteromedial and posterolateral bundles (AMB, PLB). In addition anterior tibial translation, PCL angle, PCL ratio were quantitatively measured. KT arthrometric values were reviewed for anterior tibial translation as positive or negative. The second look arthroscopy results including tear and laxity were reviewed. Results: Significant correlations were found between an AMB tear on 3D-isotropic proton density MR images and arthroscopic proven AMB tear or laxity (P < 0.05). Also, a significant correlation was observed between increased PCL ratio on 3D isotropic MRI and the arthroscopic findings such as tear, laxities of grafts (P < 0.05). KT arthrometric results were found to be significantly correlated with AMB tears (P < 0.05) and tibial tunnel cysts (P < 0.05). Conclusion: An AMB tear on 3D-isotropic MRI was correlated with arthroscopic results qualitatively and quantitatively. 3D isotropic MRI findings can aid the evaluation of ACL grafts after double bundle reconstruction.

Most athletes with anterior cruciate ligament (ACL) ruptures undergo a surgical ACL reconstruction (ACLR) and rehabilitation. On the other hand, controversy still exists because neither a reconstruction nor rehabilitation have been proven to be superior in the management of ACL injury. This study reviewed the success rates of interventions to provide recommendations for the optimal management after an ACL injury. One of the most important considerations after an ACL injury is the timing and type of intervention. At the early stages, which involve the loss of volume and strength of quadriceps femoral muscle, weight bearing (closed kinetic chain) exercises with pain management followed by high velocity resistance exercises in an open kinetic chain environment are recommended to improve the quadriceps function. After that, it is important to apply intensive isokinetic exercise with a lower extension rate. In this case, it is important to apply overload to the muscles and to simultaneously lead the co-contraction of the hamstrings. Standards are essential because the timing and type of interventions are crucial to prevent re-injury and complications, such as osteoarthritis, as well as to confirm the successful outcome of the treatment. Different interventions recommended for ACL damage have yet to reach consensus. Further studies will be needed to observe the effects of the intervention through multidisciplinary approaches.
