There was evidence of meniscus regeneration and improvement in knee pain following treatment with allogeneic human mesenchymal stem cells. These results support the study of human mesenchymal stem cells for the apparent knee-tissue regeneration and protective effects.

A systematic approach to evaluation and treatment is needed for the patient with knee dislocation. There is a paucity of high-level evidence on which to base treatment decisions. Reported controversies related to the treatment of the multiligament-injured knee include the selective use of arteriography for vascular assessment, serial physical examination with the ankle-brachial index, acute surgical treatment of all damaged structures, the selective application of preoperative and postoperative jointspanning external fixation, arthroscopic reconstruction of the anterior cruciate ligament and posterior cruciate ligament, simultaneous open reconstruction with repair of the posterolateral corner, reconstruction and/or repair of the posteromedial corner, and the use of allograft tissue. Physical Examination Vascular Assessment Popliteal artery injury and the potential for loss of the limb are of major concern following knee dislocation. Whether a patient should be evalu
