Anterior cruciate ligament reconstruction

The anterior cruciate ligament (ACL) is the most commonly reconstructed knee ligament. It is estimated that more than 100,000 new ACL injuries occur annually. This article discusses preoperative education, perioperative nursing care, surgical technique, and postoperative management of patients undergoing ACL reconstruction procedures.     

Early rehabilitation after arthroscopic reconstruction of the anterior cruciate ligament

Background. The purpose of our research was to evaluate the results of early rehabilitation after arthroscopic reconstruction of the anterior cruciate ligament, based on identical rehabilitation methods applied two weeks later. Material and methods. The research involved 30 persons, randomly divided into two groups. Each group received an identical, 12-week program of rehabilitation, differing only in the time of commencement after surgery. We analyzed the range of movement of the knee joint, the circumferences of the knee and hip, and the strength of the flexor and extensor muscle groups in the knee. Results and Conclusions. The outcome for rehabilitation of the knee is not dependent on the time when the rehabilitation process is commenced. However, in view of the occurrence of a greater number of complications when early rehabilitation is applied, individual adjustment of the timing for commencement of rehabilitation procedures would seem to be the optimal solution.     

Anterior and posterior cruciate ligament injuries

Knee pain is a common complaint in the primary care setting, and ACL and PCL injuries are common causes of knee pain. Therefore, it is important for the primary care physician to be skilled in the diagnosis and initial management of these injuries and to be aware of potential associated knee injuries. By understanding the history, mechanism of injury, physical examination maneuvers, and imaging modalities related to ACL and PCL injuries, primary care physicians can prepare themselves to make an accurate diagnosis. Then they can counsel the patients on the available treatments, initiate conservative treatment if appropriate, and facilitate an effective referral to a primary care sports medicine physician or orthopedic surgeon.     

Anterior cruciate ligament injuries. Operative and rehabilitative options

Injury to the ACL carries significant morbidity and it is an injury that afflicts and disables those enjoying a demanding active lifestyle. A decision on the most appropriate treatment is a difficult one and should be taken seriously because all treatment options require dedication and hard work for a successful outcome.     

Anterior cruciate ligament tears and associated injuries

Anterior cruciate ligament (ACL) tears are a commonly sustained sports injury, often occurring in association with meniscal tears and trauma to other ligamentous structures around the knee. Diagnosis can often be made clinically, but assessment may be difficult in the acute setting when there is a large joint effusion and severe pain. Plain radiographs may detect the presence of a joint effusion and any associated fractures. However, magnetic resonance imaging is vital for assessing acute knee injuries and plays an important role in deciding treatment options and planning surgical intervention. Some of the associated meniscal and ligamentous injuries can be subtle and may easily be overlooked if these structures are not scrutinized closely. This article will discuss the anatomy of the ACL and the mechanisms and initial clinical assessment of ACL injuries, and review the imaging features of ACL tears and some of the associated injuries, including the posterolateral corner structures. These associated injuries have important implications for determining treatment options and subsequent return to athletic activities.

Anterior cruciate ligament reconstruction of the knee

Anterior cruciate ligament (ACL) injuries affect more than 175,000 patients annually. Located in the center of the knee joint, the ACL is the major stabilizing ligament of the knee. If the ACL is injured, then the knee becomes unstable and can buckle when the person pivots. Surgeons can use autograft or allograft tissue to accomplish ACL reconstruction by using a single-bundle or double-bundle type of repair. The surgeon performs the reconstruction arthroscopically, using two ports and a small incision over the anteromedial surface of the tibia to facilitate passage of the graft and for distal fixation of the graft. Correct placement of the tibial and femoral tunnels is the most important technical aspect of the procedure. After reconstruction, the patient must undergo intense physical therapy starting one or two days after surgery. If diligent with physical therapy, then the patient can return to full activity as soon as four months after surgery.
