background :rupture of the anterior cruciate ligment (acl) is a common knee injury. the purpose of this study was to determine the balance control in football players with and without acl reconstruction in posture of injury.   methods : sway of the center of gravity of 15 patients with acl reconstruction was compared with 15 healthy, age and sex-matched subjects as the control group. all tests ...

methods we handed out questionnaires to 80 female soccer players with a history of acl injury (90 acl injuries). the players were asked about the injury characteristics, injury circumstance, maneuver being performed when the injury occurred, and playing type associated with the injury. the players responded to the questionnaire under the guidance of the medical staff of each team. results the 8...

A retrospective analysis of 48 sportsmen and women from an original series of 76 consecutive patients who had undergone a modified McIntosh repair was carried out to establish whether or not the procedure could provide a satisfactory recovery and return to previous ability. The type and level of sport before injury was compared with that after operation. Symptoms of pain and giving way, and exa...

The authors report a case of a patient that was submitted to a surgery of reconstruction of anterior cruciate ligament and collateral medial ligament repair of the left knee that complicated to a compartment syndrome.

Anterior drawer test: This test is performed with the knee flexed to approximately 90 degrees. Ideally, the patient’s foot should point straight ahead and be secured by sitting directly on the toes of the patient. The examiner’s hands are placed around the proximal tibia with the thumbs placed on the tibial tubercle. A gentle to and fro rocking motion is performed to determine the degree of ant...

OBJECTIVE Clinicians may obtain false-negative Lachman tests for tibial displacement when the trunk position of the athlete varies as the anterior cruciate ligament injury is assessed on the field, on the sideline, and in the clinic. We examined the influence of supine, semireclined, and sitting trunk positions on arthrometric laxity measurements of the knee. DESIGN AND SETTING Subjects in th...

BACKGROUND Despite the ongoing evolution of anterior cruciate ligament injury prevention methods, injury rates and the associated sex-disparity remain. Strategies capable of successfully countering key control parameters existent within the injury mechanism thus remain elusive. Forward dynamics model simulations afford an expedited means to study realistic injury causing scenarios, while contro...

BACKGROUND We are not aware of any previous studies in which independent measurements of function with validated outcome questionnaires such as the Knee Injury and Osteoarthritis Outcome Score and the International Knee Documentation Committee score were evaluated five years after reconstruction of the anterior cruciate ligament. We hypothesized that patient demographics, mechanism of injury, a...

The knee joint The knee joint is a hinge type joint made up of the thigh bone (femur) and the shin bone (tibia). The knee joint has ligaments on the inside and the outside of the joint, (medial collateral ligament and lateral collateral ligament) and ligaments inside the joint itself, (anterior cruciate and posterior cruciate ligament). The joint surfaces are covered in cartilage and the cartil...

INTRODUCTION Anterior Cruciate Ligament (ACL) injuries may lead to knee joint instability, which in turn may cause meniscal tears and cartilage lesions. Although several studies have shown that injuries of the ACL affect performances of daily activities, the three dimensional (3D) gait patterns after ACL injury and/or surgery are not yet clearly understood. The purpose of this study was twofold...
