Radiograph shows well-defined radiolucency in the lateral tibia representing a cystic lesion (arrow). However, the effect of full-thickness cartilage loss was diluted after adjustment for BMLs, and no significant association was found when evaluating different grades separately, which does not support the synovial fluid intrusion theory of SC formation. Results. 5, 1 March 2011 | The Journal of Rheumatology, Vol. 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. Subjects were not eligible to participate in the MOST study if they had rheumatoid arthritis (14), ankylosing spondylitis, psoriatic arthritis, Reiter syndrome, renal insufficiency that required hemodialysis or peritoneal dialysis, or a history of cancer (except for nonmelanoma skin cancer); had undergone or planned to undergo bilateral knee replacement surgery; were unable to walk without assistance; or were planning to move out of the area in the next 3 years. BMLs and SCs were scored from 0 to 3. We used the MR imaging definition to assess SCs, because radiographic assessment may not depict the small incident SCs in this study. 7, 1 April 2012 | Radiology, Vol. subchondral cysts (geodes) altered shape of the femoral condyles and tibial plateau; Plain radiographs are the workhorse of imaging including follow-up, although there is a poor correlation between radiographic findings and clinical symptoms 1,2. The most common abnormalities were bone marrow necrosis, fibrosis, and trabecular abnormalities (1). 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). 11, Osteoarthritis and Cartilage, Vol. 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. Subchondral bone cysts commonly occur adjacent to a treated focal cartilage defect and are possibly connected to the joint cavity. A multitude of differential diagnoses of subchondral BMLs may present with a similar aspect and signal characteristics. 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. Two musculoskeletal radiologists (F.W.R. Other more common findings that may be mistaken for pathologic BMLs are patches of red … If readers disagreed on the presence of OA, readings were adjudicated by a panel of three readers (two nonauthors and D.T.F.). Enhancement of subchondral cysts was evaluated on contrast enhanced MRI as grade 0 (absent), grade 1 (partial enhancement), or grade 2 (full enhancement). Knee pain was assessed by using the Western Ontario and McMaster University pain subscale. 1, 15 January 2013 | Clinical Rheumatology, Vol. 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. 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 cyst–like lesions (SCs) are a common finding in patients with knee osteoarthritis (OA). 6, 22 September 2016 | Nature Reviews Rheumatology, Vol. Surgical Technique. Introduction. Radiographs were presented sequentially with readers blinded to all clinical data and to MR images. Patients may develop subchondral cysts in areas of marrow edema; the clinical relevance of subchondral cysts concerning symptomatic osteoarthritis needs to be explored. 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. 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. Bone marrow lesions (BMLs) around the knee are a common magnetic resonance imaging (MRI) finding. 41, No. 27, No. 19, No. 10.1111/j.1740-8261.1998.tb00334.x. Two-dimensional MRI analyses of tibiofemoral subregions have demonstrated that subchondral BMLs predict cartilage loss and subchondral bone attrition at the same subregion [49, 50]. The subchondral bone acts as a shock absorber in weight-bearing joints, such as … The MRI evaluation in JOG included the joint features of subchondral BMLs, subchondral cysts, cartilage, meniscus, effusion and synovitis using the Whole Organ Magnetic Resonance Imaging Score (WORMS) method .

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). These were the most common abnormalities found at histologic examination, whereas only 40% of patients had small amounts of edema. 6, 30 November 2015 | The American Journal of Sports Medicine, Vol. is vice president of and partner in Boston Imaging Core Lab (BICL) (Boston, Mass), a company that provides radiologic image assessment services. The Baker’s cyst was easily palpated and grossly seen with the patient in the prone position. 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. Structural abnormalities (osteophytes, cartilage loss, bone marrow lesions (BMLs), subchondral cysts, meniscal abnormalities, effusion, Baker's cyst) at 9 patellofemoral and tibiofemoral locations were scored following the knee OA scoring system. Osteonecrosis and bone infarcts, inflammation, tumor, transient idiopathic bone marrow edema, red marrow and post-surgical alterations should also be considered. The MRI also demonstrated a large Baker’s cyst and a group of small loculated subchondral cysts in the posterior medial condyle. To assess the association of prevalent bone marrow edema–like lesions (BMLs) and full-thickness cartilage loss with incident subchondral cyst–like lesions (SCs) in the knee to evaluate the bone contusion versus synovial fluid intrusion theories of SC formation. No baseline full-thickness cartilage loss was detected in this subregion. Radiographs were read in approximately 8 months without interruption. 15, No. 42, No. 6, Seminars in Arthritis and Rheumatism, Vol. Subchondral bone marrow edema-like lesions represent a predictor of subchondral cyst–like lesions (SCs), which supports the bone contusion theory of SC formation. Knee osteoarthritis (OA) is a painful and debilitating disease characterized by cartilage deterioration and altered subchondral bone. Geodes, also known as a subchondral cysts, are well-defined lytic lesions at the periarticular surfaces. BMLs were defined as poorly delineated areas of hyperintensity directly adjacent to the subchondral plate on STIR and proton density–weighted fat-suppressed MR images. Detection of SCs on radiographs (sometimes referred in radiography as geodes) is usually possible when they are big enough to produce areas of hyperlucency in the subchondral bone, which usually occurs in advanced disease. 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 Background: Subchondral bone cysts are a widely observed, but poorly understood, feature in patients with knee osteoarthritis (OA). 11, 13 April 2016 | Knee Surgery, Sports Traumatology, Arthroscopy, Vol. A total of 2141 subregions were finally excluded. 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. Enhancement of subchondral cysts was evaluated on contrast-enhanced MRI as grade 0 (absent), grade 1 (partial enhancement), or grade 2 (full enhancement). The fracture can be seen as irregular linear or curvilinear subchondral low signal intensity structure near the subchondral bone plate of low signal intensity in T1-weighted images and also sometimes, but not always in T2-weighted images 1,2,4-8. Methods: The preoperative knee of 42 knee arthroplasty patients was scanned using QCT. We showed that both prevalent BMLs and full-thickness cartilage loss predict SC formation longitudinally, with the association much stronger for prevalent BMLs. They can develop in … Patients with acute trauma, infection, neoplasm, or osteonecrosis were excluded. 36, No. Whole-Organ Magnetic Resonance Imaging Score, International Journal of Paleopathology, Vol. BMLs, which represent focal bone remodeling due to overloading, are predictors of pain and progression of cartilage damage in OA (15,20) and are potential treatment targets. However, despite the growing interest on BMLs in multiple pathological conditions, they remain controversial not only for the still unknown role in the etiopathological processes, but also in terms of clinical impact and treatment. The underlying BML may have vanished (20). 2, No. A P value less than .05 was considered to indicate a significant difference. Subchondral bone cysts (SBC) have been identified in patients with knee osteoarthritis (OA) as a cause of greater pain, loss of cartilage and increased chance of joint replacement surgery. To our knowledge, this is the largest prospective and longitudinal study to assess the temporal relationship between MR imaging–detected BMLs and full-thickness cartilage loss and SCs in the same subregion of the knee for the evaluation of the pathogenesis of SCs in light of the synovial fluid intrusion and bone contusion theories. MR imaging depicted 171 osteophytes and 51 subchondral cysts. 14, No. Figure 3b: (a) Coronal STIR MR image at baseline shows a grade 1 BML at the central subregion of the medial tibia (arrowheads). Although a plain xray would reveal the true nature of the lesion, in some cases MRI is the first imaging modality used. However, readers were not aware of the aim of the study at the time of MR imaging assessment. 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). 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. Funding: This work was supported by National Institute on Aging (grants U01-AG-18947, U01-AG-18832, U01-AG-19069, and U01-AG-18820). 23, No. We obtained written informed consent from all patients. Osteoarthr. Is Subchondral Acetabular Edema or Cystic Change on MRI a Contraindication for Hip Arthroscopy in Patients With Femoroacetabular Impingement? Cartilage morphology and signal intensity were scored semiquantitatively from 0 to 6 in each subregion (0, normal thickness and signal intensity; 1, normal thickness but increased signal intensity on proton density–weighted or STIR images; 2.0, partial-thickness focal defect < 1 cm in greatest width [Fig 2]; 2.5, full-thickness focal defect < 1 cm in greatest width; 3, multiple areas of partial-thickness defects intermixed with areas of normal thickness or a grade 2.0 defect wider than 1 cm but < 75% of the region; 4, diffuse [≥75% of the region] partial-thickness loss; 5, multiple areas of full-thickness loss or a grade 2.5 lesion wider than 1 cm but < 75% of the region; 6, diffuse [≥75% of the region] full-thickness loss). 10.1016/j.joca.2006.05.011 [Google Scholar] Chan P.

The procedure is initiated by aspiration of the bone marrow from the ipsilateral iliac crest using a sharp trocar with a … 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. 12, Current Opinion in Rheumatology, Vol. (A) Chronic lateral knee pain in 23-year-old man. Examinations were performed at the University of Alabama at Birmingham and at the University of Iowa at Iowa City with the same MR unit. 11, 3 August 2016 | Orthopedics, Vol. Osteoarthritic cysts are also referred to as subchondral cysts, pseudocysts, or geodes (the preferred European term) and may range from 2 to 20 mm in diameter. A subchondral cyst (Fig. Subchondral insufficiency fractures are non-traumatic fractures that occur immediately below the cartilage of a joint. 12, No. By continuing you agree to the use of cookies. Prevalent BMLs strongly predict incident SCs in the same subregion, even after adjustment for full-thickness cartilage loss, which supports the bone contusion theory of SC formation. The magnetic resonance imaging (MRI) in 4 cases of subchondral cyst at the knee joint region, were acquired from a 1.5 Tesla imager. In the present study, we included all participants with available baseline and 30-month follow-up MR imaging results. A recent study (12) demonstrated that BMLs are highly associated with SCs in the same subregion of the knee. However, of all analyzed MR imaging studies, only one knee showed a subacute tibial depression fracture at follow-up and was excluded. Subjects considered at high risk for knee OA included those who were overweight or obese; those with knee pain, aching or stiffness on most of the past 30 days, a history of knee injury that made it difficult to walk for at least 1 week; or those who underwent previous knee surgery. What Is a Subchondral Bone Cyst? 4, Cytokine & Growth Factor Reviews, Vol. bone marrow edema-like lesions and subchondral cysts. Introduction. 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. (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. 05, No. 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). 7, No. Methods. 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. 12, 1 September 2015 | The Journal of Rheumatology, Vol. SCs have a characteristic appearance on MR images, demonstrating well-defined rounded areas of fluidlike signal intensity on unenhanced images (1,2). 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). 45, No. After adjustment for full-thickness cartilage loss, prevalent BMLs showed a strong and significant association with incident SCs in the same subregion, with an odds ratio of 12.9 (95% confidence interval [CI]: 8.9, 18.6). One thousand two hundred eighty-three knees (one knee per patient, 16 349 subregions assessable at baseline and follow-up examinations) were included. 38, No. 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. In our study, most (92.6%) incident SCs detected were small (grade 1). 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). 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. An MRI visible cartilage abnormality was adjacent to 87% (20/23) of cysts. Background: Choice of appropriate MR pulse sequence is important for any research studies using imaging-derived data. Indeed, we found that, without any adjustment, grades 5 and 6 were significantly associated with incident SCs compared with subregions with no full-thickness cartilage loss at baseline. In the knee, cyst-like degenerations may occur resulting from changes in the conjunctive matrix of some articular structures. Therapeutic approaches targeting BMLs, including unloading or pharmacologic intervention, may delay or prevent cyst development, but this is unknown. However, that was a cross-sectional study, and no temporal relationship between these two features could be assessed. Surgical treatment options for New York patients may vary, based on the size, type and symptoms of the hip cyst. It is meaningful to investigate associations between subchondral bone cyst parameters (e.g., number, size, and location) and associated articular degeneration in OA pathology. An MRI allows him to see both the bony structures of the hip as well as the soft tissues. 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). 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. No adjacent full-thickness cartilage loss is seen. Many subregions were excluded because they were not assessable, mainly because of motion artifacts or field inhomogeneity at baseline and/or at follow-up, which did not allow scoring of the features evaluated in these subregions (cartilage morphology, BMLs, and SCs). 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). 4, 20 August 2014 | Journal of Magnetic Resonance Imaging, Vol. A bone radiographs were read in approximately 8 months without interruption in approximately 8 months interruption.
