Sophia Y Kim, Charles E Spritzer, Gangadhar M Utturkar, Alison P Toth, William E Garrett, Louis E DeFrate
BACKGROUND: The motions causing noncontact anterior cruciate ligament (ACL) injury remain unclear. Tibiofemoral bone bruises are believed to be the result of joint impact near the time of ACL rupture. The locations and frequencies of these bone bruises have been reported, but there are limited data quantifying knee position and orientation near the time of injury based on these contusions. HYPOTHESIS: Knee position and orientation near the time of noncontact ACL injury include extension and anterior tibial translation...

BACKGROUND: Bone bruising is commonly observed on magnetic resonance imaging (MRI) after non-contact anterior cruciate ligament (ACL) injury. OBJECTIVES: The primary objective of this study was to determine if the location and prevalence of tibial and femoral bone bruises after ACL injury can be explained by specific injury mechanism(s). The secondary objective was to determine whether the bone-bruise literature supports sex-specific injury mechanism(s). We hypothesized that most studies would report bone bruising in the lateral femoral condyle (LFC) and on the posterior lateral tibial plateau (LTP)...

PURPOSE: To determine whether there is a relationship between the size of the bone bruise volume after an acute anterior cruciate ligament (ACL) rupture and the presence of meniscal tears in the medial and lateral compartment. METHODS: Following Institutional Review Board approval, 50 patients with an acute ACL rupture and MRI imaging within 30 days of injury were identified. Two musculoskeletal radiologists evaluated the lateral and medial menisci and graded them as one of the following: no meniscal tear, tear of one meniscus (medial or lateral) or tear of both menisci (medial and lateral)...

BACKGROUND: Bone bruising, commonly found on magnetic resonance imaging (MRI) after anterior cruciate ligament (ACL) injury, may be associated with intra-articular injuries, but little is known about this association. PURPOSE: To examine demographic factors and intra-articular injuries associated with bone bruising in patients undergoing ACL reconstruction. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: Patients with ACL injury who had an MRI within 6 weeks and arthroscopy within 3 months of injury were included in this prospective study (N = 171)...

INTRODUCTION: The purpose of this study was to assess the natural history of bone bruise and bone mineral density (BMD) after traumatic hip dislocations and conservatively treated acetabular fractures. Our hypothesis was that poor bone quality can influence degree of bone bruise and, in time, cause degenerative changes. MATERIALS AND METHODS: Eight consecutive patients with traumatic hip dislocations and five patients with conservatively treated fractures in the femoral head and/or acetabulum were included...

BACKGROUND/AIM: Bone bruise is a common finding in acutely injured knee examined by magnetic resonance (MR). The aim of the study was to determine the association of bone bruise frequency with postinjury lesions of anterior cruciate ligament (ACL) and menisci. Bone bruise involves posttraumatic bone marrow change with hemorrhages, edema and microtrabecular fractures without disruption of adjacent cortices or articular cartilage. MR imaging is a method of choice for detecting bone bruises which can not be seen on conventional radiographic techniques...

BACKGROUND: Bone bruises located on the lateral femoral condyle and posterolateral tibia are commonly associated with anterior cruciate ligament (ACL) injuries and may contribute to the high risk for knee osteoarthritis after ACL injury. The resultant footprint (location) of a bone bruise after ACL injury provides evidence of the inciting injury mechanism. Purpose/ HYPOTHESIS: (1) To analyze tibial and femoral articular cartilage pressure distributions during normal landing and injury simulations, and (2) to evaluate ACL strains for conditions that lead to articular cartilage pressure distributions similar to bone bruise patterns associated with ACL injury...

BACKGROUND: Earlier studies have found that tibial eminence fractures (TEFs) in children are rarely associated with additional injuries. In skeletally immature patients with this fracture, the rate of meniscal injury is reported to be less than 5%. Most earlier studies that evaluate TEFs are based on conventional radiographic findings and do not address injuries to the subchondral bone and soft tissues of the knee. Therefore, the purpose of this study was to assess additional injuries, specifically bone bruises and meniscal tears identified by magnetic resonance imaging (MRI) in skeletally immature patients who have sustained a TEF...

BACKGROUND: Bone bruises on magnetic resonance imaging (MRI) are common in patients with acute knee ligament injuries and have been well described for injuries involving the anterior and posterior cruciate ligaments and the medial collateral ligament. These have not yet been described in detail for posterolateral corner injuries. HYPOTHESIS: Acute grade III posterolateral corner (PLC) injuries are often accompanied by bone bruises located in the medial compartment...

PURPOSE: To evaluate traumatized bone marrow with a dual-energy (DE) computed tomographic (CT) virtual noncalcium technique. MATERIALS AND METHODS: In this prospective institutional review board-approved study, 21 patients with an acute knee trauma underwent DE CT and magnetic resonance (MR) imaging. A software application was used to virtually subtract calcium from the images. Presence of fractures was noted, and presence of bone bruise was rated on a four-point scale for six femoral and tibial regions by two radiologists...

The term bone bruise, in modern medicine, is still a relatively young one, which followed the advent of MRI. Resolution takes between 12 and 24 weeks, however clinical significance is unknown. We present the case of an 18-year-old male who developed bone bruising of his lateral femoral condyle, associated with meniscal injury and anterior cruciate ligament rupture, following a fall from a push bike. A subsequent injury then led to collapse of his lateral femoral condyle following initial resolution of his symptoms...

Articular cartilage and its supporting bone functional conditions are tightly coupled as injuries of either adversely affects joint mechanical environment. The objective of this study was set to quantitatively investigate the extent of alterations in the mechanical environment of cartilage and knee joint in presence of commonly observed osteochondral defects. An existing validated finite element model of a knee joint was used to construct a refined model of the tibial lateral compartment including proximal tibial bony structures...

Osteonecrosis of the knee is extremely rare following anterior cruciate ligament (ACL) reconstruction surgery. We report a case of osteonecrosis of the lateral femoral condyle in a patient after ACL reconstruction. The osteonecrotic lesion occurred in the same area as a large bone bruise, which was sustained at the time of the initial injury. We hypothesize that the combination of bone bruising and femoral tunnel drilling for ACL reconstruction may have compromised the overall vascularity of the articular cartilage and the subchondral bone, thereby resulting in osteonecrosis...

Bone mineral density (BMD) loss is one of the secondary problems occurring in knee joint after injury of anterior cruciate ligament (ACL). The effect of this injury on BMDs of specific regions is not clear. The aim of this study was to investigate BMD changes in unreconstructed ACL-deficient knees with subregion analysis of dual energy X-ray absorptiometry (DEXA). Precision and reliability studies of DEXA revealed that two region of interests (ROI) in medial condyle, two ROIs in lateral femoral condyle (LFC) and one ROI in medial tibial plateau (MTP) in anteroposterior (AP) DXA view and one ROI for each of distal femur, proximal tibia and patella in lateral view had high reproducibility and reliability...

BACKGROUND: The knee is one of the most frequently injured joints, including 80 000 anterior cruciate ligament (ACL) tears in the United States each year. Bone bruises are seen in over 80% of patients with ACL injuries, and have been associated with an overt loss of cartilage overlying those regions within 6 months of injury. HYPOTHESIS: The level of contact pressure developed in the human knee joint and the extent of articular cartilage and underlying subchondral bone injuries will depend on the mechanism of applied loads/moments during rupture of the ACL...

With the advent of magnetic resonance imaging (MRI) after knee injuries interest has focussed on the clinical relevance of different concomitant osseous damage. Different MRI- sequences reveal varying characteristics of such lesions. Prospective data of 69 patients with MRI-detected sub-acute subchondral fractures or bone bruises according to the classification of Mink was recorded. Function, symptoms (Noyes) and activity (Tegner) were assessed at the time of first MRI and 7,4 months later including a follow-up MRI using T 2-weighted fat saturated (fs) fast-spin-echo-sequences (FSE), T 1-weighted spin echo (SE) sequences, Proton-density-weighted spin echo-sequences (SE) and T 2-weighted (fs) gradient-echo-sequences...

OBJECTIVE: We developed an animal model of bone injury to determine the timing of the MR appearance of bone bruises and to follow these changes over time. MATERIALS AND METHODS: We performed serial MRI of 16 knees of eight swine with one nontraumatized knee as a control and 15 knees traumatized by direct patellar impact injuries using a force-calibrated device. All knees were imaged on a 1.5-T scanner using an 8-channel phased-array coil with T1-weighted, fat-saturated T2-weighted and STIR sequences...
