No statistically significant differences were found for age (P = .53) and sex (P = .87) when considering included versus excluded subregions. 14, No. Introduction. 10.1016/j.joca.2006.05.011 [Google Scholar] Chan P. M. B., Wen C., Yang W. C., Yan C., Chiu K. (2017). SBCs, bone marrow lesion (BML), and hip-knee-ankle (HKA) axis were measured by using validated methods. (B) Sagittal PD FS image shows well-defined subchondral cyst (arrow) with surrounding BML (arrowheads). Introduction. Figure 2: Coronal STIR MR image demonstrates a partial-thickness focal defect of cartilage (grade 2.0) in the central subregion of the medial femoral condyle (arrow). These cysts are produced in areas of damaged articular cartilage, subjacent to the underlying subarticular cortical plate. 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. An overview of the published literature is presented. Copyright © 2020 Elsevier B.V. or its licensors or contributors. There was no apparent relationship between severity of full-thickness cartilage loss at baseline and incident SCs. Methods. (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. The cause of SCs in subjects with or at risk for knee OA is still unknown. Osteonecrosis and bone infarcts, inflammation, tumor, transient idiopathic bone marrow edema, red marrow and post-surgical alterations should also be considered. The synovial fluid intrusion theory posits that elevated intraarticular pressure leads to the intrusion of joint fluid into the subchondral bone through fissured or ulcerated cartilage (3,6), with subsequent development of cystic cavities. Subchondral bone marrow edema-like lesions represent a predictor of subchondral cyst–like lesions (SCs), which supports the bone contusion theory of SC formation. Methods: The preoperative knee of 42 knee arthroplasty patients was scanned using QCT. Figure 3a: (a) Coronal STIR MR image at baseline shows a grade 1 BML at the central subregion of the medial tibia (arrowheads). The MRI also demonstrated a large Baker’s cyst and a group of small loculated subchondral cysts in the posterior medial condyle. 3, 27 September 2011 | Rheumatology, Vol. Design: Retrospective cohort of 32 patients with two sequential knee MRI. The most likely cause is either synovial fluid intrusion or bone contusions.

Supportive of this theory is the fact that cysts are often observed in areas of the knee exhibiting concomitant bone marrow edema–like lesions (BMLs) that show histologic features of bone trauma, including areas of necrosis. Is Subchondral Acetabular Edema or Cystic Change on MRI a Contraindication for Hip Arthroscopy in Patients With Femoroacetabular Impingement? After HTO, the evolution of cysts was evaluated on MRI performed with a five year follow-up on the 72 knees with pre-operative cysts. As the joint tries to repair itself, the remodeling of bone can often b… Surgical treatment options for New York patients may vary, based on the size, type and symptoms of the hip cyst. In the present study, we included all participants with available baseline and 30-month follow-up MR imaging results. A musculoskeletal radiologist and a rheumatologist, who were not authors (both with more than 10 years of experience reading study radiographs) and were blinded to clinical data, independently graded the images according to the Kellgren-Lawrence scale (17). 5, 1 December 2017 | Scientific Reports, Vol. 5, American Journal of Roentgenology, Vol. Published by Elsevier Ltd.

Open Archive in partnership with OsteoArthritis Society International, MRI-detected subchondral bone marrow signal alterations of the knee joint: terminology, imaging appearance, relevance and radiological differential diagnosis. The Health Insurance Portability and Accountability Act–compliant study protocol was approved by the Institutional Review Boards at the University of Iowa, University of Alabama at Birmingham, University of California at San Francisco, and Boston University School of Medicine. The aim of this study was to test the synovial fluid intrusion versus the bone contusion theory of SC formation in subjects with or at risk for knee OA by evaluating the association of prevalent BMLs and full-thickness cartilage loss with incident SCs in the same subregion of the knee by using MR imaging. If readers disagreed on the presence of OA, readings were adjudicated by a panel of three readers (two nonauthors and D.T.F.). However, the effect was significantly attenuated after adjustment for BMLs, with an odds ratio of 1.4 (95% CI: 1.0, 2.0; P = .036). 23, No. 1998, 39: 167-173. Of 19 153 subregions analyzed initially, 663 (3.5%) exhibited SCs at baseline and were excluded. Furthermore, there was no apparent relationship between severity of full-thickness cartilage loss at baseline and incident SCs (Table 2). However, despite the growing interest on BMLs in multiple pathological … subchondral tibial cysts in patients with knee OA and to explore relationships between proximal tibial subchondral cyst parameters and subchondral bone density as well as clinical characteristics of OA (alignment, joint space narrowing (JSN), OA severity, pain) in patients with knee OA. An MRI allows him to see both the bony structures of the hip as well as the soft tissues. Thus, grades 2.5, 5, and 6 include full-thickness cartilage loss, but the other grades do not. 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). Knee pain was assessed by using the Western Ontario and McMaster University pain subscale. Dr. Nwachukwu will often be able to see acetabular paralabral cysts or subchondral cysts on an MRI scan. 9, No. At the onset of disease, the space between the joint bones will begin to narrow due to cartilage degeneration.2 2. Subchondral cyst–like lesions (SCs) are a common finding in patients with knee osteoarthritis (OA). The presence and size of subchondral cysts and bone marrow edema-like lesions (BMLs) were scored semiquantitatively in each subregion on non-contrast-enhanced MRI from 0 to 3. Furthermore, a larger size of BMLs at baseline was associated with an increased risk for the development of SCs at follow-up, which also favors the bone contusion theory. We assessed the longitudinal association of prevalent BMLs (score ≥ 1) and full-thickness cartilage loss (grades 2.5, 5, and 6) with incident SCs (score ≥ 1) on a per-subregion basis by using logistic regression with generalized estimating equations to account for correlations among the subregions within a knee (using one knee per person). WORMS is a validated research tool for semiquantitative assessment of knee OA. A subchondral cyst (Fig. No statistically significant differences were found for age (P = .97) and sex (P = .68) when considering subregions with incident SCs. ; 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. All statistical calculations were performed by using software (SAS, version 9.1 for Windows; SAS Institute, Cary, NC). The tibiofemoral and patellofemoral joints were subdivided into 14 subregions. BMLs and SCs were scored from 0 to 3. A recommendation for terminology is provided and the relevance of these imaging findings for osteoarthritis (OA) research is emphasized. Cyst … She had reported that the Baker’s cyst had been there for many years and periodically aspirated by different doctors. Presence of osteophytes and subchondral cysts in four locations of tibiofemoral joint (medial and lateral femur and tibia) was recorded. 23, No. 19, No. Subchondral bone cyst presents as a tumor mimic due to the following scenario: A patient with a known cancer develops worsening pain in a joint. To discuss terminology, radiological differential diagnoses and significance of magnetic resonance imaging (MRI)-detected subchondral bone marrow lesions (BMLs) of the knee joint. 1, 2 January 2013 | BMC Musculoskeletal Disorders, Vol. 28, No. Tomosynthesis had a higher sensitivity for osteophyte detection in left and right lateral femur (0.96 vs 0.75, P = .025, and 1.00 vs 0.71, P = .008, respectively), right medial femur (0.94 vs 0.72, P = .046), and right lateral tibia (1.00 vs 0.83, P = .046). The weighted κ coefficients of intrareader observer reliability (studies in 30 knees randomly selected) were 0.8 and 0.94 for the readings of BMLs (comparing scores 0–3 in each subregion), 0.86 and 0.93 for SCs (comparing scores 0–3 in each subregion), and 0.88 for cartilage morphology (comparing scores 0–6 in each subregion). Figure 4a: (a) Sagittal proton density–weighted fat-suppressed MR image at baseline shows a grade 1 BML at the anterior (trochlear) subregion of the lateral femur (arrowheads). No evidence of epithelial lining has been detected in prior histologic studies (2–5). 12, Current Opinion in Rheumatology, Vol. Cyst not associated with OA. 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). Osteoarthritis typically develops in stages: 1. Prevalent full-thickness cartilage loss showed a significant association with incident SCs in the same subregion, with an odds ratio of 5.4 (95% CI: 4.1, 7.2; P < .0001), compared with subregions without baseline full-thickness cartilage loss. 45, No. Magnetic resonance imaging (MRI) of the knee joint is one of the most commonly requested in general radiological practise examinations and belongs to the core clinical practice in most MRI units along with spinal and brain MRI. Rhaney and Lamb (4) have demonstrated the histologic similarity of subchondral cysts and the surrounding subchondral bone marrow, which suggests that subchondral cyst formation is secondary to subchondral bone marrow necrosis due to increased loading. The subchondral cyst was determined as the source of the excess synovial fluid filling up the Baker’s cyst. 05, No. 19, No. A recent cross-sectional study (12) showed SCs to be highly associated with BMLs in the same subregion of the knee in patients with or at risk for knee OA, which favors the bone contusion theory of SC formation. are shareholders in and one author (F.W.R.)
