subchondral cyst knee mri

However, readers were not aware of the aim of the study at the time of MR imaging assessment. However, of all analyzed MR imaging studies, only one knee showed a subacute tibial depression fracture at follow-up and was excluded. Overall, 87% (20/23) of subchondral cysts were subjacent to an MRI visible cartilage abnormality (any grade). An MRI allows him to see both the bony structures of the hip as well as the soft tissues. It's a fluid-filled sac that forms in one or both of the bones that make up a joint. Useful MR scoring parameters include lesion location, lesion size in 3 planes, subchondral bone marrow edema, subchondral cyst formation and/or sclerosis, status of the overlying cartilage, contour depression of the articular bone plate. Cyst not associated with OA. At the onset of disease, the space between the joint bones will begin to narrow due to cartilage degeneration.2 2. 10.1111/j.1740-8261.1998.tb00334.x. Dr. Nwachukwu will often be able to see acetabular paralabral cysts or subchondral cysts on an MRI scan. 19, No. Subchondral bone cysts (SBCs) were detected on 72 knees of these 140 knees. 6, 18 March 2011 | Rheumatology, Vol. Subchondral cysts have always been taught to be one of the cardinal radiological features of knee osteoarthritis but are not well understood. Subregions without BMLs (score = 0) and without full-thickness cartilage loss (scores 0, 1, 2, 3, and 4) were considered the reference group. 9, No. 6, Open Journal of Orthopedics, Vol. The cysts occur in the subchondral bone, the layer of bone just under the cartilage. Mean subject age was 62.3 years ± 7.9 (standard deviation), and mean subject body mass index was 30.1 kg/m2 ± 4.9 (range, 18.0–55.8 kg/m2). However, we may only hypothesize this in the present study, because several visits within short time intervals including MR imaging were not available in the MOST study to detect such causality.

A longitudinal subanalysis of the individual BML and cartilage morphology grades was performed. MRI tends to make these lesions look much more worrisome than they really are. Subchondral cysts are of variable size from a f… subchondral bone marrow edema on dual-energy CT; MRI. Although a plain xray would reveal the true nature of the lesion, in some cases MRI is the first imaging modality used. 27, No. the presence of pain in chondral pathology of the knee.1 Therefore, subchondral pathology, visible as sclerosis and/ or cysts (plain radiographs) and hyperintensity (on mag-netic resonance imaging [MRI]), has been targeted as a viable entity to treat in a therapeutic strategy to relieve pain.2 Inhibition of subchondral lesions has been shown (A) Chronic lateral knee pain in 23-year-old man. The Baker’s cyst was easily palpated and grossly seen with the patient in the prone position. The exact pathogenesis of these degenerative cysts is not certain. (b) Sagittal proton density–weighted fat-suppressed MR image at 30-month follow-up shows an incident SC (arrow) in the middle of the BML depicted at baseline. Knee osteoarthritis (OA) is a painful and debilitating disease characterized by cartilage deterioration and altered subchondral bone. Recently, there has been increasing interest in the role of subchondral bone cysts in OA progression; in particular how subchondral bone cysts may influence pain [1,2,3], or how subchondral bone cysts influence subchondral bone mechanical behaviour []. 39, No. The most common abnormalities were bone marrow necrosis, fibrosis, and trabecular abnormalities (1). In a retrospective study of 32 patients who underwent two sequential knee MR imaging examinations, Carrino et al (13) reported that 92% of incident SCs developed in regions with BMLs, which favors the bone contusion theory. Figure 3b: (a) Coronal STIR MR image at baseline shows a grade 1 BML at the central subregion of the medial tibia (arrowheads). 48-Month Data from the Osteoarthritis Initiative, Search under the Cartilage: A Gamut of Subchondral Lesions, Think Different: Sorting Out Osteochondral Lesions of the Knee, Subchondroplasty: A New Minimally Invasive Procedure for Treatment of Knee Pain Associated with Arthritis. Prevalent BMLs were found in 1843 subregions (11.3%), prevalent full-thickness cartilage loss was found in 1624 subregions (9.9%), and incident SCs were found in 216 subregions (1.3%). According to the synovial fluid intrusion theory (3,6), SCs should develop only in subregions with full-thickness cartilage loss, where breaches of the articular surface could allow synovial fluid and/or synovial tissue to intrude into the subchondral bone. We found a high incidence of concomitant occurrence of subchondral cysts with a ruptured anterior cruciate ligament (ACL) in all of these cases. We showed that both prevalent BMLs and full-thickness cartilage loss predict SC formation longitudinally, with the association much stronger for prevalent BMLs. These cysts are produced in areas of damaged articular cartilage, subjacent to the underlying subarticular cortical plate. The resolution of the MR images obtained in the MOST study might be below the threshold for detection of small full-thickness fissuring of cartilage, which may be responsible for synovial fluid intrusion. No adjacent full-thickness cartilage loss is seen. BML and SC sizes were scored from 0 to 3 on the basis of the extent of regional involvement (0, none; 1, <25% of the subregion; 2, 25%–50% of the subregion; 3, >50% of the subregion). We used the MR imaging definition to assess SCs, because radiographic assessment may not depict the small incident SCs in this study. 17, No. MRI shows a well defined, regular, complex heterogenously altered lobulated completely intraosseous lesion in the subchondral location of the glenoid with no expansion / bleed / labral / cartilage / joint involvement. Examinations were performed at the University of Alabama at Birmingham and at the University of Iowa at Iowa City with the same MR unit. Subchondral insufficiency fractures are non-traumatic fractures that occur immediately below the cartilage of a joint. Prevalent BMLs showed a strong association with incident SCs in the same subregion, with an odds ratio of 15.0 (95% confidence interval [CI]: 10.9, 20.5; P < .0001), compared with subregions without prevalent BMLs (Figs 3 and 4). 2, No. 12, 1 September 2015 | The Journal of Rheumatology, Vol. The HIPAA-compliant protocol was approved by the institutional review boards of all participating centers, and written informed consent was obtained from all participants. (B) Sagittal PD FS image shows well-defined subchondral cyst (arrow) with surrounding BML (arrowheads). No statistically significant differences were found for age (P = .97) and sex (P = .68) when considering subregions with incident SCs. Enhancement of subchondral cysts was evaluated on contrast-enhanced MRI as grade 0 (absent), grade 1 (partial enhancement), or grade 2 (full enhancement). Baseline and follow-up MR images were presented paired and sequentially to the readers, with the chronological order known to the readers. 41, No. The evidence for local and central pain processing, Semiquantitative assessment of subchondral bone marrow edema-like lesions and subchondral cysts of the knee at 3T MRI: A comparison between intermediate-weighted fat-suppressed spin echo and Dual Echo Steady State sequences, Mechanical Loading: Bone Remodeling and Cartilage Maintenance, Frequency of Bone Marrow Lesions and Association with Pain Severity: Results from a Population-based Symptomatic Knee Cohort, Comment on: Bone marrow lesions in people with knee osteoarthritis predict progression of disease and joint replacement: a longitudinal study, Magnetic Resonance Imaging in Knee Osteoarthritis Research: Semiquantitative and Compositional Assessment, Rapidly Progressive Osteoarthritis: Biomechanical Considerations, Osteoarthritis year 2010 in review: imaging, Crosstalk between cartilage and bone: When bone cytokines matter, Articular Cartilage in the Knee: Current MR Imaging Techniques and Applications in Clinical Practice and Research1, Subchondral Bone Marrow Edema in Patients with Degeneration of the Articular Cartilage of the Knee Joint. The IW fs sequence should be used for determination of lesion extent whenever the size of subchondral bone marrow edema-like lesions is the focus of attention. Patients with acute trauma, infection, neoplasm, or osteonecrosis were excluded. Radiographs were presented sequentially with readers blinded to all clinical data and to MR images. In the present study, we included all participants with available baseline and 30-month follow-up MR imaging results. 3, 27 September 2011 | Rheumatology, Vol. If this theory is valid, SCs should develop only in regions of the knee exhibiting full-thickness cartilage loss or fissuring. 38, No. 3, 16 February 2017 | Clinical Reviews in Bone and Mineral Metabolism, Vol. In our study, most (92.6%) incident SCs detected were small (grade 1). Med. Osteoarthritis typically develops in stages: 1. Second, even though spin-echo MR imaging sequences are widely accepted as an accurate technique to evaluate articular cartilage (22–24), we do not have arthroscopic or histologic proof of cartilage status. A multitude of differential diagnoses of subchondral BMLs may present with a similar aspect and signal characteristics. Two authors (M.D.C. and M.D.M.) Baseline and follow-up MR readings were performed during a period of 2 years. Baird DK, Hathcock JT, Kincaid SA, Rumph PF, Kammermann J, Widmer WR, Visco D, Sweet D: Low-field magnetic resonance imaging of early subchondral cyst-like lesions in induced cranial cruciate ligament deficient dogs. An MRI visible cartilage abnormality was adjacent to 87% (20/23) of cysts. 10, 1 December 2013 | The Journal of Rheumatology, Vol. 2011; 12 (1):198. The association of prevalent BMLs and full-thickness cartilage loss with incident SCs in the same subregion was assessed by using logistic regression with mutual adjustment for both predictors. Incident SCs, considered the outcome, were defined as grade 0 at baseline and grade 1 or greater at follow-up. We use cookies to help provide and enhance our service and tailor content and ads. No baseline full-thickness cartilage loss was detected in this subregion. On the other hand, the bone contusion theory posits that SCs are a consequence of traumatic bone necrosis after impact of two opposing articular surfaces (4,7). For subregions demonstrating incident SCs without prevalent BMLs at baseline, it is still possible that an incident BML developed after the baseline visit that turned into a subchondral cyst, which was then observed at follow-up. 263, No. Because there is a high prevalence of BMLs in subregions exhibiting cartilage damage (20,21), we adjusted these results for the presence of concomitant BMLs when considering full-thickness cartilage loss as the predictor. 12, 9 September 2011 | BMC Musculoskeletal Disorders, Vol. The weighted κ coefficients of interobserver reliability (studies in 30 knees randomly selected and read by both readers) were 0.66 for the readings of BMLs (comparing scores 0–3 in each subregion), 0.57 for SCs (comparing scores 0–3 in each subregion), and 0.78 for cartilage morphology (comparing scores 0–6 in each subregion). (A) Chronic lateral knee pain in 23-year-old man. MRI of bone marrow edema-like signal in the pathogenesis of subchondral cysts. 12, No. Dr. Nwachukwu will often be able to see acetabular paralabral cysts or subchondral cysts on an MRI scan. Radiographs were read in approximately 8 months without interruption. 1, Osteoarthritis and Cartilage, Vol. Enter your email address below and we will send you your username, If the address matches an existing account you will receive an email with instructions to retrieve your username. Patients with acute trauma, infection, neoplasm, or osteonecrosis were excluded. 15, No. However, that was a cross-sectional study, and no temporal relationship between these two features could be assessed. 5, Progress in Biophysics and Molecular Biology, Vol. Tibiofemoral OA was considered present at radiography if the Kellgren-Lawrence grade was 2 or greater. The most likely cause is either synovial fluid intrusion or bone contusions. In the present study, we showed that prevalent BMLs are strongly associated with incident SCs in the same subregion of the knee compared with those subregions without BMLs at baseline, which supports the bone contusion theory of SC formation. If readers disagreed on the presence of OA, readings were adjudicated by a panel of three readers (two nonauthors and D.T.F.). Surgical Technique. Thus, according to the bone contusion theory, MR imaging–detected BMLs should represent the source of SCs in subjects with or at risk for knee OA. The underlying BML may have vanished (20). Of 19 153 subregions analyzed initially, 663 (3.5%) exhibited SCs at baseline and were excluded. Subchondral cyst. Subchondral cyst–like lesions (SCs) are a common finding in patients with knee osteoarthritis (OA). After adjustment for BMLs, prevalent full-thickness cartilage loss showed a significant but much less important association with incident SCs in the same subregion (odds ratio, 1.4; 95% CI: 1.0, 2.0). To determine if a relationship exists between bone marrow edema-like signal and subchondral cysts on magnetic resonance imaging (MRI). 2, Journal of Orthopaedic Translation, Vol. These lesions have a characteristic appearance on magnetic resonance (MR) images, demonstrating well-defined rounded areas of fluidlike signal intensity on unenhanced images (1,2).No evidence of epithelial lining has been detected in prior histologic studies (2–5). SBCs, bone marrow lesion (BML), and hip-knee-ankle (HKA) axis were measured by using validated methods. BMLs are defined as noncystic subchondral areas of ill-defined hyperintensity on proton density–weighted, intermediate-weighted, T2-weighted, or short tau inversion-recovery (STIR) MR images and areas of hypointensity on T1-weighted spin-echo MR images (1,8–10). MR images were obtained in both knees at baseline and 30-month follow-up with a 1.0-T dedicated extremity unit (OrthOne; ONI Medical Systems, Wilmington, Mass) with a circumferential extremity coil by using fat-suppressed fast spin-echo proton density–weighted sequences in the sagittal (repetition time msec/echo time msec, 4800/35; 3-mm section thickness; 0-mm intersection gap; 32 sections; 288 × 192 matrix; number of signals acquired, two; 140 × 140-mm field of view; echo train length, eight) and axial (4680/13; 3-mm section thickness; 0-mm intersection gap; 20 sections; 288 × 192 matrix; number of signals acquired, two; 140 × 140-mm field of view; echo train length, eight) planes and a STIR sequence in the coronal plane (6650/15; inversion time, 100 msec; 3-mm section thickness; 0-mm intersection gap; 28 sections; 256 × 192 matrix; number of signals acquired, two; 140-mm2 field of view; echo train length, eight). Prevalent BMLs strongly predicted incident SCs in the same subregion longitudinally, even after adjustment for full-thickness cartilage loss, which supports the bone contusion theory of SC formation. https://doi.org/10.1016/j.joca.2009.03.012. Subregions with prevalent SCs (score ≥ 1) were excluded. SCs were defined as well-delineated areas of hyperintensity directly adjacent to the subchondral plate on STIR and proton density–weighted fat-suppressed MR images. Sixty percent were women (n = 776), 86.4% were white (n = 1109), and 44.4% had tibiofemoral radiographically depicted OA (Kellgren-Lawrence grade, ≥2) at baseline (n = 570). ; clinical studies, M.D.C., F.W.R., Y.Z., C.E.L., G.Y.E., A.G.; statistical analysis, Y.Z., J.N., Y.Z., A.G.; and manuscript editing, all authors. Objective: To determine if a relationship exists between bone marrow edema-like signal and subchondral cysts on magnetic resonance imaging (MRI). No evidence of epithelial lining has been detected in prior histologic studies (2–5). Furthermore, in the same study, in about half of cases, SCs were found in subregions with no areas of full-thickness cartilage loss. 23, No. The aim of this study was to compare semiquantitative assessment of subchondral bone marrow edema-like lesions and subchondral cysts using intermediate-weighted (IW) fat-suppressed (fs) spin echo and Dual Echo Steady State (DESS) sequences on 3 T MRI. Magnetic resonance images were acquired at baseline and 30-month follow-up and read semiquantitatively by using the Whole-Organ Magnetic Resonance Imaging Score system. Design: Retrospective cohort of 32 patients with two sequential knee MRI. There was no apparent relationship between severity of full-thickness cartilage loss at baseline and incident SCs. 2, No. post-traumatic, in sport injuries, in rheumatological disorders, in oncological imaging), the number of incidental cystic and “cyst-like” lesions in and around the knee joint found on routine knee MRI scans has also increased [1–4]. When comparing the MR imaging features of the tibial plateau in 16 patients with severe knee OA with histologic specimens prior to joint replacement, Zanetti et al (1) found that abnormal tissue appeared in only about half of the regions with MR imaging–detected BMLs. 36, No. First and probably most important is that no arthroscopic or histologic correlation was performed. However, spin-echo MR imaging is able to depict and help differentiate BMLs and SCs, in accordance with previous studies correlating the MR imaging appearance of these abnormalities and histologic findings (1,2,11). Keywords: bone marrow lesion, cyst, MRI, knee, osteoarthritis * Correspondence: dhayashi@bu.edu However, the association of baseline BMLs and full-thickness cartilage loss with incident SCs was not assessed in that cohort.

The subspinous region was not considered in this study because it is not covered by articular cartilage. The Multicenter Osteoarthritis study is a longitudinal study of individuals who have or are at risk for knee osteoarthritis. According to the WORMS system (18), grades 2.5, 5, and 6 for cartilage morphology indicate subregions with full-thickness cartilage loss, with different amounts of the cartilage surface involved. Published by Elsevier Ltd. All rights reserved. and A.G., with 6 and 8 years of experience, respectively, in standardized semiquantitative MR imaging assessment of knee OA), who were blinded to OA grade at radiography and clinical data, graded BMLs, cartilage status, and SCs according to the Whole-Organ Magnetic Resonance Imaging Score (WORMS) system (18). No baseline full-thickness cartilage loss was detected in this subregion. Given the fact that magnetic resonance imaging (MRI) is being performed more frequently for assessment of the knee joint (e.g. 2, 19 January 2011 | RadioGraphics, Vol. 1, 15 January 2013 | Clinical Rheumatology, Vol. Full-thickness cartilage loss is seen in this subregion at follow-up. To our surprise, the effects of grades 5 and 6 of cartilage morphology were completely diluted after this adjustment, and no association was found between prevalent full-thickness cartilage loss and incident SCs when each grade was assessed separately, which speaks against the synovial fluid intrusion theory of SC formation. These lesions have a characteristic appearance on magnetic resonance (MR) images, demonstrating well-defined rounded areas of fluidlike signal intensity on unenhanced images (1,2). Surgical treatment options for New York patients may vary, based on the size, type and symptoms of the hip cyst. Assessment of subchondral non-cystic ill-defined BMLs on gradient echo-type sequences should be avoided as they will underestimate the size of the lesion. Because BMLs are highly associated with cartilage damage in the same subregion of the knee (20,21), we adjusted for full-thickness cartilage loss when testing prevalent BML (bone contusion theory) as the predictor. Marrow edema-like signal size always changed with cyst development: increased in 6/11 (54.5%), decreased in 2/11 (18.1%) and resolved in 3/11 (27.2%). bone marrow edema-like lesions and subchondral cysts. A subchondral cyst (Fig. 5, American Journal of Roentgenology, Vol. is vice president of and partner in Boston Imaging Core Lab (BICL) (Boston, Mass), a company that provides radiologic image assessment services. No adjacent full-thickness cartilage loss is seen. A P value less than .05 was considered to indicate a significant difference.

Bone marrow lesions (BMLs) around the knee are a common magnetic resonance imaging (MRI) finding. Is subchondral bone cyst formation in non-load-bearing region of osteoarthritic knee a vascular problem? 24) is an intraosseous cyst which occurs beneath an articular surface of a bone. They were recruited from two U.S. communities, Birmingham, Alabama, and Iowa City, Iowa, through mass mailing of letters and study brochures, which were supplemented by media and community outreach campaigns.
