Ganglion cysts of the cruciate ligaments of the knee are rare and their pathogenesis is uncertain. A few cases of the cyst of the posterior cruciate ligament were reported in the literature. We have arthroscopically treated sucessfully the ganglion cysts of the posterior cruciate ligament through the anteromedial portal. We reported three cases of ganglion cyst of the posterior cruciate ligament with brief of literatures.

Isolated posterior cruciate ligament injuries are rare and their management is controversial. But, there is general concept that a bony avulsion of posterior cruciate ligament should be repaired. The treatments for the bony avulsion of posterior cruciate ligament were conservative treatment, open reduction and internal fixation and arthroscopic fixation. We report 2 cases of posterior cruciate ligament avulsion fractures, which were arthroscopically reduced and stabilized with cannulated screws and Kirschner wires, and introduce the arthroscopic fixation technique.

Background: The purpose of this study was to investigate the usefulness of quadriceps exercise for improvement of knee extensor muscular function after cruciate ligament reconstruction. Methods: Participate in 18 of patients with cruciate ligament reconstruction, ACL & PCL reconstruction was 9 of patients, respectively. All subjects instructed that quadriceps exercise repeated daily, composed to QSE(quadriceps femoris setting exercise) and SLR(straight leg raises). Knee extensor muscular function was measured before and after quadriceps exercise. Initial test was measured before cruciate ligament reconstruction, and retest was measured 6month after cruciate ligament reconstruction. Results: Knee extensor muscular function significantly increased in both ACL and PCL reconstruction(P<0.05). Conclusion: The results of this study indicated that quadriceps exercise useful for improve knee extensor muscular function in patients with cruciate ligament reconstruction.

Ganglion cysts have been described in all joints. In the knee, although the finding of meniscal degenerative cysts is fairly common, a few cases have been reported concerning ganglion cysts of anterior cruciate ligament. However, ganglion cysts of posterior cruciate ligament are quite rare. We experienced two cases of ganglion cyst in the posterior cruciate ligament, which were treated successfully with arthroscopic debridement.

The anterior cruciate ligament(ACL) is, perhaps, the most intriguing component of the knee joint. Initially referred to crucial ligament because of the cruciate or crossed arrangement or the anterior and posterior ligaments within the knee. the irony or the ACL being crucial to the well-being or the joint has only recently appreciated. The anterior cruciate ligament of human knee joint is a complex structure and its orientation, construct and biology arc directly related to the knee function as a constraint of knee joint motion. In addition to its functional role as a static stabilizer or the knee. the ACL has a unique neurovascular system. The vascular anatomy of the ACL plays a crucial role in the repair and reconstruction of the ligament, and the neuroreceptors found in its substance suggest a possible proprioceptive role for the ligament. The structural complexity of the ACL allows the ligament to function through the normal range of motion as a static stabilizer or the knee. hut it also makes the exact duplication of this structure very difficult. A comprehensive knowledge or the anatomy of the ACL can provide the orthopedic surgeon with a blueprint for the idealized repair and reconstruction of this most complex structure.

This study aims to find out the standardized test criteria regarding patients with the anterior cruciate ligament damage by identifying the degree of the flexion gap of femur and tibia upon bending of the anterior cruciate ligament in order to carry out the accurate test of such impairment. On the standardized test method and judgement criteria upon the anterior cruciate ligament test using Telos, it has been shown that there was no significant difference in the results according to the position of a fixed roller in the anterior cruciate ligament test for normal patients. However, in a test for patients who had undergone the anterior cruciate ligament reconstruction, it has been shown that the measured values of the anterior cruciate ligament tended to be pushed when the position of a fixed roller was less than 1cm in the test according to the position of a fixed roller of Telos (less than 1cm, more than 3cm), and this was statistically significant. The anterior cruciate ligament test (knee stress test) is a limited method used in orthopedics and rehabilitation medicine, and there have been no standardized test guidelines available yet although numerous ligament measurement tests have been performed. In addition, since the measured values are often different depending on testers even on the test that is expected to give the same result, the reproducibility of the test is still low. Accordingly, it is considered that the criteria for the anterior cruciate ligament test need to be established, and this would contribute to the accuracy of the diagnosis through the accurate test and standardized measurements.

As with anterior cruciate ligament reconstruction, posterior cruciate ligament(PCL) reconstruction requires a good understanding of the anatomy and biomechanical properties of the PCL to place the graft correctly as well as to choose the appropriate structure and material for the graft. The anatomy and function of the PCL can be somewhat confusing and continuing to evolve so far. Recent studies have focused on the insertion site anatomy and the identification of the functional components of the ligament. The issue of the ligament isometry and the role of PCL in knee kinematics are still totally resolved. This article can be provided an update on current concepts of the anatomy and biomechanics of the PCL through literature reviews. A clear understanding of these knowledges enables the clinicians to diagnose injuries to the PCL accurately and to reconstruct these structures successfully.

Purpose : To report a short-term clinical results and technical method of thermal shrinkage with radiofrequency device for anterior and posterior cruciate ligament laxity which is not suitable to indications of reconstructive surgery. Materials and Methods : Nine cases of anterior cruciate ligament injuries (ACL), 5 cases of posterior cruciate ligament (PCL) injuries and 3 cases of combined anterior and posterior cruciate ligament injuries, in which the condition is not indicated as reconstructive surgery, are investigated. The follow-up period averaged 6 months. Results : Instability in living activity, limping and pain were improved with excellent results. But, posterior cruciate ligament thermal shrinkage revealed as recurrent knee laxity progressively Conclusions : The result of thermal shrinkage for partial tear of cruciated ligament was excellent. We believe this procedure is applicable to partial tear of the ACL or PCL which reconstructive surgery is not indicated. Long-term follow-up results were needed.

Ganglion in the anterior cruciate ligament is quite rare finding at the time of knee arthroscopy. We experienced a 58 years old female pateint with a ganglion in the anterior cruciate ligamentwho complained gradual development of flexion contracture of left knee joint and treated with arthroscopic excision of ganglion resulted in freedom from flexion contracture of her knee joint.

In the present paper the current clinical knowledge about proprioception is given for the shoulder, knee, ankle, elbow and the radiocarpal joint. Proprioceptive capabilities are decreased after knee joint injury such as anterior cruciate ligament. Joint position sense is significantly improved by cruciate reconstruction. Thus, we review of the articles for the proprioception of the anterior cruciate ligament of the knee joint. The present information on proprioception will influence our clinical practice in the future. We should choose surgical procedures that not only reconstruct the anatomy, but also the neurophysiologic feed-back mechanism.
