Mặc dù phương pháp điều trị chấn thương ligamentous đã liên tục được cải thiện, nhiều câu hỏi vẫn còn về việc tăng cường tốc độ, chất lượng, và đầy đủ chữa bệnh dây chằng. Được biết, khả năng của một chấn thương dây chằng để chữa bệnh phụ thuộc vào nhiều yếu tố, bao gồm cả vị trí giải phẫu, | Healing and Repair of Ligament Injuries in the Knee Savio . Woo PhD DSc Tracy M. Vogrin MS and Steven D. Abramowitch Abstract Although methods of treating ligamentous injuries have continually improved many questions remain about enhancing the rate quality and completeness of ligament healing. It is known that the ability of a torn ligament to heal depends on a variety of factors including anatomic location presence of associated injuries and selected treatment modality. A grade III injury of the medial collateral ligament MCL of the knee usually heals spontaneously. Surgical repair followed by immobilization of an isolated MCL tear does not enhance the healing process. In contrast tears of the anterior cruciate ligament ACL and the posterior cruciate ligament often require surgical reconstruction. The MCL component of a combined ACL-MCL injury has a worse prognosis than an isolated MCL injury. The results of animal studies suggest that nonoperative treatment of an MCL injury is effective if combined with operative reconstruction of the ACL. Experimentation using animal models has helped to define the effects of ligament location associated injuries intrinsic factors surgical repair reconstruction and exercise on ligament healing. New techniques utilizing growth factors and cell and gene therapies may offer the potential to enhance the rate and quality of healing of ligaments of the knee as well as other ligaments in the body. J Am Acad Orthop Surg 2000 8 364-372 The incidence of knee ligament injuries resulting from sports activities has stimulated interest in ligament healing. Clinical experience has shown that an isolated ruptured medial collateral ligament MCL of the knee can heal with nonoperative care but that a midsubstance tear of the anterior cruciate ligament ACL usually does not. An ACL deficiency can result in chronic knee instability with a 2-degree injury to other soft-tissue structures and eventually progressive osteoarthritis. Primary surgical .
