The femoral intercondylar notch width was measured in 93 patients with chronic anterior cruciate ligament (ACL) insufficiency (Group 1), in 62 patients with an acute tear of the ACL (Group 2), and in 38 fresh anatomic specimen knees (Group 3). In six of the specimen knees, further anatomic studies of the intercondylar notch were performed after tissue removal. The average intercondylar distance was 16.1 mm in Group 1, 18.1 mm in Group 2, and 20.4 mm in Group 3. All differences were highly significant. The intercondylar notch was wider in the posterior part and had no crossing bony ridges but had generally concave walls, which provided a functional shelf for the ACL to insert on the lateral side. Significant osteophyte formation and stenosis of the anterior outlet of the intercondylar notch occur early in the ACL-deficient knee. A narrow anterior outlet of the intercondylar notch without osteophytes was also found in knees with an acute ACL rupture. At reconstruction of the ACL, notchplasty should be performed concomitantly.

Ganglion cysts are commonly found in areas of constant mechanical stress such as the joints and tendons of the wrist or hand as well as the anterior aspect of the ankle. In the knee, parameniscal cysts are often encountered secondary to meniscal tears or articular degeneration. Intra-articular ganglion cysts are uncommon and often arise from the cruciate ligaments and are found in the intercondylar notch.

Case: A 16-year-old woman presented with acute on chronic knee pain and instability following a twisting injury. The tibial insertion of the anterior cruciate ligament (ACL) was nonvisualized on magnetic resonance imaging. A cord-like ACL, originating from the lateral intercondylar notch and inserting smoothly into the anterior horn of the intact lateral meniscus, was found on arthroscopy.

Objectives: The literature does not show any studies that correlate between the morphological parameters of knee and functional outcome after anterior cruciate ligament reconstruction. The purpose of this study was to establish a correlation of morphological parameters of the knee in (magnetic resonance imaging) MRI with functional outcome in patients who underwent anterior cruciate ligament reconstruction.
Material And Methods: This was an observational study which included 63 patients who underwent anterior cruciate ligament reconstruction.

The aim of this preliminary study was to morphologically and dimensionally characterize the cat's olfactory bulb in the sagittal plane and to establish potential relationships with the cranial conformation, based on the study of in vivo MRI images. Midsagittal and transverse T2-weighted images of the head of 40 cats subjected to MRI were selected. For each animal, the skull index was calculated to classify the cranial conformation.
