To evaluate the possible relationship between femoral intercondylar notch stenosis and anterior cruciate ligament injuries in pivoting and cutting sports, a 2-year prospective study was performed on intercollegiate athletes at a Division I university. Daily practice times and athlete participation in practices and games were recorded for each sport during the 2-year period. Bilateral intercondy...

Abstract Introduction: The presence of cruciate ligaments are very important for normal knee kinematics. Knee arthroplasty prostheses, in which these ligaments are maintained, have better kinematics. The aim of the present study was to investigate the association between femoral intercondylar notch narrowing in radiography and clinical and histopathologic integrity of anterior cruciate li...

Females demonstrated 2-9 times higher ACL injury rate, narrow notch width and higher joint laxity in multi-planar directions [1,2]. One of potential ACL injury mechanisms is ACL impingement against the lateral wall of the femoral intercondylar notch [3], expressed as elongated and deformed ACL geometry [3] and contact area and contact pressure between the ACL and the intercondylar notch [4]. Ho...

Objective: To compare intercondylar notch width index and reverse notch width index in cases with and without anterior cruciate ligament tears. Patients and methods: 33 patients with a positive lachman’s test and pivot shift and a complete ACL tear on MRI were taken as cases. 33 patients with knee pain but a negative Lachman’s test and pivot shift and no ACL tear on MRI were taken as controls. ...

The principal purpose of this prospective study was to examine intercondylar notch size and the value of inner angle of lateral femoral condyle as the risk factors for noncontact anterior cruciate ligament ACL injury and than to correlate them to the physical values of the athletes such as body mass index (BMI), hight, wight, etc. There are indentified two type of risk factors, external include...

OBJECTIVE A multifactorial combination of predictors may increase anterior cruciate ligament (ACL) injury risk in athletes. The objective of this twin study was to examine these risk factors to identify commonalities in risk factors that predisposed female fraternal twins to ACL injury. METHODS Female twins in high-risk sports were prospectively measured prior to an injury for neuromuscular c...

Background/Objective: It has been proposed that a narrow intercondylar notch may increase the risk of anterior cruciate ligament (ACL) injury but the data are conflicting. We performed this cross-sectional study to investigate if a narrow intercondylar notch width is a risk factor for ACL tears. Patients and Methods: All adult patients with knee problems, who were referred to the MRI department...

We assessed the possible association between an aggressive intercondylar notchplasty and histopathologic, radiographic, and gait changes to the knee. Three groups of six adult greyhounds were observed for 6 months. Group I dogs had a sham operation. Group II dogs had a 4-mm notchplasty of the lateral femoral condyle where it articulates with the lateral tibial spine. Group III dogs had a 7- to ...

Background: Exposure of the insertion site of the anterior cruciate ligament (ACL) is important for appropriate tunnel placement in ACL reconstruction surgery. However, observing the femoral ACL insertion site via the standard anterolateral portal is sometimes difficult. In this study, we compared views of the femoral ACL insertion site between 30-degree and the 45-degree arthroscopes. Methods:...

The aim of this study was to research whether the patients with knee osteoarthritis (OA) exist intercondylar notch stenosis and the relationship between stenosis and OA complicated with anterior cruciate ligament (ACL) injury from magnetic resonance imaging (MRI).A total of 79 cases of moderate-severe OA patients and 71 cases of healthy people were collected; among these OA patients, 38 were OA...
