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.

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.

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 giant cell tumor of tendon sheath is very rarely present inside the knee joint. The authors report a case of intraarticular giant cell tumor of tendon sheath arising from posterior cruciate ligament which was successfully excised arthroscopically using posterior trans-septal portal at the time of arthroscopic reconstruction of anterior cruciate ligament.

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.

Posterior cruciate ligament reconstructions are dangerous procedure in terms of neurovascular complication. But deep vein thrombosis and associated compartment syndrome after posterior cruciate ligament reconstruction has not been reported, yet. We have experienced a patient who developed a deep vein thrombosis and compartment syndrome after revision posterior cruciate ligament reconstructive surgery, and report the importance of diagnosis and management with the discussions.

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.

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.

Purpose: We investigated the natural history of acute, isolated posterior cruciate ligament injuries treated conservatively. Materials and Methods: Between February 1999 and October 2006, we evaluated retrospectively the results of acute, isolated posterior cruciate ligament injuries treated conservatively. The subjects consisted of 21 patients. At initial and follow up visits physical examination, $KT-2000^{TM}$ arthrometer and MRI were performed to assess improvement on the knee stability and continuity of the posterior cruciate ligament. IKDC (International Knee Documentation Committee) knee scoring and quadriceps muscle strength were also checked in all population. Comparing the results of initial and follow up examinations we assessed the natural history of acute, isolated posterior cruciate ligament injuries treated conservatively. The mean follow up period was 22.7 months. Results: The posterior drawer test showed 14 cases of Grade I, 6 cases of Grade II and 1 case of Grade III progressing 18 cases of Grade I and 3 cases of Grade II. The mean difference of 5.7mm by $KT-2000^{TM}$ arthrometer was changed Into 2.7mm and the continuity of posterior cruciate ligament initially checked by 48.1% on MRI increased to 69.7%. The mean quadriceps muscle strength was grade 'Good' and mean IKDC knee score was nearly grade 'A'. Conclusion: Our study suggests that patients with acute, isolated posterior cruciate ligament injuries treated conservatively may get good clinical outcomes on clinical situation and MRI.
