With distal hand gently extend knee. & Staheli, L.T. Changes in the CCD angle is the result of changes in the stress patterns applied to the hip joint. There are two main joints in the knee: 1) the tibiofemoral joint where the tibia meet the femur 2) the patellofemoral joint where the kneecap (or patella) meets the femur. Genu valgum is the Latin-derived term used to describe knock-knee deformity. Despite an initially satisfactory surgical outcome, pain, dysfunction, and implant failure can occur over time. Although rare, posterolateral corner (PLC) injuries can result in sustained instability and failed cruciate ligament reconstruction if they are not diagnosed. Unable to process the form. 1 (1): 46. | Find, read and cite all the research you . During normal growth the tibiofemoral angle reaches zero between 18 to 24 months, after which it turns into a physiologic genu valgus, finally reaching the adult configuration by the age of 6 to 7 years. Kinematic MRI techniques were developed because various pathologic conditions are dependent on the specific position of the joint or in response to loading or stress. Importantly, static- Brian D.

This volume provides an up-to-date and comprehensive review of imaging of the knee. In the first part of the book, the various techniques employed when imaging the knee are discussed in detail. The varus deformity can be quantified with the hip-knee-ankle angle (HKA), which measures the angle between the mechanical axis of the femur and the center of the ankle joint on AP, full-length, weight-bearing radiographs. It is our responsibility to be able to describe features we see on radiographs to other health care professionals. Reference article, Radiopaedia.org. Knee angle and intermalleolar (IM) or intercondylar (IC) distance were measured in 196 white children aged 6 months to 11 years to establish normal limits of tibiofemoral angle. Soft tissue calcifications pop up all of the time, and it behooves the radiologist to say something intelligent about them. (The colloquial expression "cartilage damage" might also include meniscal tears, which is an altogether separate category of disease.) (2013), 2. The management of genu varum primarily focuses on the treatment of the underlying condition (e.g. (2011). Journal of Pediatric Orthopedics, 13, 259 . X-rays pass through the knee from anterior to posterior at a 90° angle to the lower leg. As the knee extends, the patella should slide over the lateral femoral condyle and pop into the groove. The lower extremity alignment was determined using the mechanical tibiofemoral or hip-knee-ankle (HKA) angle measured with CT-scan in non-weight-bearing conditions 17 The coronal alignment of the lower limb is usually assessed using various axes [6] . At its origin it is thin and pointed, but it gradually increases in size as it descends. .

The hip region is located lateral and anterior to the gluteal region, inferior to the iliac crest, and overlying the greater trochanter of the femur, or "thigh bone". Such artifacts can result in areas of increased signal intensity on short-TE pulse sequences, particularly along the deep margin of the tendon, with decreasing prominence on T2-weighted acquisitions [ 75 ]. Patients with trochlear dysplasia often have increased medial and lateral patellar translation near full extension and at 45 degrees of knee flexion. There are two condylar joints between the femur and tibia (tibiofemoral). of chronic chondromalacia include subluxation, an increased quadriceps angle, quadriceps imbalance, posttraumatic malalignment, excessive lateral pressure syndrome and PCL injuries. ; The Q angle can be measured in laying or standing.

The flexor digitorum longus is situated on the tibial side of the leg. The anatomy of the PLC was once thought to be perplexing and esoteric—in part because of the varying nomenclature applied to this region in the literature, which added unnecessary complexity. Soft Tissue Calcifications. Espandar, Ramin, Mortazavi, Seyed Mohammad-Javad, Baghdadi, Taghi. First-time patellar dislocation typically occurs with twisting knee motions, during which the medial ligamentous stabilizers rupture, and the patella strikes against the lateral femoral condyle. Recent studies of OA of the knee have shown that OA involvement of the patellofemoral joint compartment, either isolated or together with medial compartment OA, is associated with more pain and lower function level than when OA is limited to the medial or lateral tibiofemoral compartments 2,3. The knee joint is a synovial joint which connects the femur (thigh bone), the longest bone in the body, to the tibia (shin bone). Its presentation in adolescence is rare. Several pathologic conditions may manifest as an osteochondral lesion of the knee that consists of a localized abnormality involving subchondral marrow, subchondral bone, and articular cartilage.
