Arthroscopy. To determine the interobserver reliability of the International Cartilage Repair Society (ICRS) grading system of chondral lesions in cadavers, to determine the intraobserver reliability of the ICRS grading system comparing arthroscopy and video assessment, and to compare the arthroscopic ICRS grading system with histological grading of lesion depth. The Wilcoxon signed rank test was used to analyze paired data (preoperative and postoperative). Reliability and validity of the arthroscopic International Cartilage Repair Society classification system: correlation with . As higher grades are more likely to be unstable and need intervention, there is a utility to using a corresponding grading system in preoperative MR imaging (19) . assessing cartilage damage assessment using LIPA and 3.0 Tesla MRI (T2 mapping and DT imaging), this study investigates the usefulness of the various methods. The most traditional and well-known include that devised by Outerbridge , whereas one of the most recent and detailed is the International Cartilage Repair Society (ICRS) classification .

Disorganized architecture of fibrocartilage following microfracture technique—high-power light microscopy, hematoxylin & OBJECTIVE: The International Cartilage Repair Society classification is the one mainly used to define chondral defects. Puhakka J, Paatela T, Salonius E, Muhonen V, Meller A, Vasara A, Kautiainen H, Kosola J, Kiviranta I. The decision in Göteborg was to continue with IKDC but there will also be comparative studies with the KOOS ( www.koos.nu) The clinical evaluation system can also be combined with the . Download Table | International Cartilage Repair Society classification from publication: Usefulness of using laser-induced photoacoustic measurement and 3.0 Tesla MRI to assess knee cartilage . Intermediate-weighted fast SE and 3D fat-suppressed T1-weighted GRE sequences are most commonly used for this purpose ( , Table 1 ). Radius - on the opposite side of the lower arm to the ulna. macroscopic (International Cartilage Repair Society [ICRS] classification) and histological evaluations (modified Mankin score and Osteoarthritis Research Society International [OARSI] histological grade). The arthroscopic indication for HTO is a grade 2 or 3 chondral lesion, according to Outerbridge 13 or International Cartilage Repair Society 14 classification, at the medial compartment, associated with a varus knee and a good lateral compartment. rently, the International Cartilage Repair Society (ICRS) classification is the gold standard for assessing lesion sta-bility,2,10,18 and it is determined intraoperatively under either arthroscopic or direct observation. The results were evaluated with the Knee injury and Osteoarthritis Outcome Score (KOOS), the Lysholm score and a Visual Analogue Scale (VAS) for pain. Google Scholar The International Cartilage Repair Society (ICRS) Hyaline Cartilage Lesion Classification System is the international standard for classifying the severity of chondral lesions [28, 29]. Currently, the International Cartilage Repair Society (ICRS) classification is the gold standard for assessing lesion stability, 2,10,18 and it is determined intraoperatively under either arthroscopic or direct observation. This study evaluates the reliability of the International Cartilage . 2017;33(6):1219-24. ICRS - Articular cartilage injury classification Study design: Controlled laboratory study. Patient has one or two defects in the target knee with a defect-grade of III or IV according to the International Cartilage Repair Society (ICRS) classification or grade III or IV ICRS classification of osteochondritis dissecans lesions (ICRS-OCD). A The ICRS classification was used to assess the cartilage of the femoral head (see Table 1 for the definition of the grades). There was a discussion regarding the use of IKDC-1999 vs KOOS (Knee Injury and Osteoarthritis Outcome Score). Purpose: To evaluate the reliability of the ICRS scoring system using an animal cartilage repair model. Arthroscopic International Cartilage Repair Society Classification System Has Only Moderate Reliability in a Porcine Cartilage Repair Model. International Cartilage Repair Society 1397. Repair cartilage may be evaluated by using the same acquisition techniques that are used for evaluating the native cartilage, as recommended by the International Cartilage Repair Society (, 10). additional classification systems used to define chondral defects include the International Cartilage Repair Society (ICRS) classification and the Noyes classification. The elbow is a hinge joint that is made up of three bones: Humerus - the upper arm bone. Humeroulnar - a simple hinge joint . Ulna - on the inside of the lower arm when the arms are down and palms facing forward. The International Cartilage Repair Society classification based on intraoperative findings is the current gold standard for assessing the lesion severity for OCD [3,[18][19][20]. classified as grade 4 according to the International Carti-lage Repair Society (ICRS) classification system5 and with a of size >400 mm2. However, this classification does not include delamination. To date, only Smith et al.15 have made an attempt to val- unstable on probing; fragment not dislocated; complete discontinuity of the "dead in situ" lesion; stage IV. Note: ICRS classification can be estimated by MRI at visit 1 if no data is available from medical history. ICRS is the main forum for international collaboration in cartilaginous tissue research. ICRS-Osteochondritis dissecans classification ICRS-Cartilage Repair Assessment system The ICRS Clinical Cartilage Injury Evaluation system-2000 was developed dur ing ICRS 2000 Standards Workshop at Schloss Münchenwiler, Switzerland, January 27-30, 2000 and further discussed during the

Different histological scoring systems in cartilage repair exist such as the comprehensive O'Driscoll7, 8, 9, the simple Pineda scale7, 10, the Bern score 11 and the International Cartilage Repair Society (ICRS) Visual Histological Assessment Scale 12. Cartilage tissue assessment. Background: The International Cartilage Repair Society (ICRS) score was designed for arthroscopic use to evaluate the quality of cartilage repair. Patient has an intact meniscus; a maximum of 50% resection is allowed. Radius - on the opposite side of the lower arm to the ulna. In grade III "dead in situ" lesions with cartilage discontinuity and subchondral bone instability as well as grade IV lesions with dislocation of the fragment, according to the International Cartilage Repair Society classification system,2 surgical treatment is indicated.3 C The Arthro-BST was used to assess the same points assessed by the ICRS classification.D Cartilage sections were made by cutting . Lesions were staged using the classification of the International Cartilage Repair Society (ICRS) as well as the classification established by Berndt and Harty, and modified by Loomer (Table 1). These three bones connect to form three joints within a capsule. In ICRS grading, cartilage defects are classified into four stages based on the lesion depth. MRI was performed preoperatively to measure the T2 and the apparent diffusion coefficient. Modified International Cartilage Repair Society Chondral Injury Classification System Figure 2a. Because OCD of the elbow most frequently presents in adolescents, a noninvasive method to assess the instability These two scoring systems were specifically designed to evaluate the macroscopic outcome of cartilage repair in an attempt to simplify and focus the scoring system on clinical needs. Although long-term studies have reported very satisfying clinical results, they are scarce. stable on probing; partial discontinuity of the lesion from the host bone; stage III.

The mal-alignment, ligament laxity, other pathology needed to be corrected before. The objective of the study is to describe the characteristics of this lesion to better explain its classification in the context of chondral lesions of the hip. Osteochondral Lesions of the Talus Sara Lyn Miniaci-Coxhead, MD Dr. Miniaci-Coxhead or an immediate family member serves as a board member, owner, officer, or committee member of the American Orthopaedic Foot and Ankle Society. The correct grading and diagnosis of the lesions allow surgeons to select the most appropriate treatment. The Arthro-BST induces streaming potentials using 37 microelectrodes. Reliability and validity of the arthroscopic international cartilage repair society classification system: correlation with histological assessment of depth. B Schematic drawing of the Arthro-BST. cartilage defects had grade 3-4 according to ICRS (International Cartilage Repair Society) Classification System(12,13). It is hypothesized that the classification system of the International Cartilage Repair Society (ICRS) will allow for improved assessment of lesion grade and stability in OCD. Table 1. Therefore, the International Cartilage Repair Society (ICRS) classification remains the gold standard to determine OCD lesion stability. To grade a lesion, the sur-geon must first débride the cartilage defect during arthroscopy. Repair cartilage may be evaluated by using the same acquisition techniques that are used for evaluating the native cartilage, as recommended by the International Cartilage Repair Society (, 10). This chapter is adapted from Chao W, Freeland E, Dedini R: Osteochondral Lesions of the Talus in Chou LB, ed: Orthopaedic… Am J Sports Med, 49(6):1524-1529, 18 Mar 2021 Currently, the International Cartilage Repair Society (ICRS) classification is the gold standard for assessing lesion stability, 2,10,18 and it is determined intraoperatively under either arthroscopic or direct observation. International Cartilage Repair Society (ICRS Classification System for OCD Lesions) (A) Grade 1: Thickening of cartilage without disruption 1a: Bone marrow edema 1b: Fluid at lesion-bone interface Grade 2: Cartilage breached, fluid at interface, but not entire interface Grade 3: Cartilage completely disrupted with fluid interface surrounding . For young patients with cartilage defects, the emergence of clinically applicable cell therapy for biological joint reconstruction is an appealing prospect. Characteristics of the evaluated patients and comparison according to the therapeutic outcomes. Twenty-five patients (50%) had undergone a previous operative intervention for cartilage lesions of grade 3 and 4 per International Cartilage Repair Society classification repair (Table 1) on the ipsilateral knee at least 1 year before PRP treatment (S1 group), while 25 patients did not undergo any previous operative intervention for the knee . Methods: This study included 24 patients with OCD of the knee (19 males, 5 females; mean age, 16 years).Patients were treated according to the ICRS classification.
