Objectives: To analyze the intra and interobserverreliability of the International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine (ISAKOS) classification of meniscal tears. Methods: Thearthroscopic classification of meniscal lesions created by the ISAKOS was used. Thirty one arthroscopic videos, made between June and December 2013,with different meniscal tear characteristics were analyzedby three orthopedic surgeons (two specialists in knee surgery and a fellowship), twice at an interval of 30 days. The Kappa Coefficients (k) was used to assess the intraobserver reliability and intraclass correlation coefficient (ICC) for interobserverreliability. Results: The averageintraobserver reliability was for the first observer 51%, the second 65% and the third 58%, reaching moderate agreement according to the Kappa coefficient used by Landis and Koch. Regarding interobserver reliability, good agreement (ICC = 0.71) was obtained as the intraclass correlation coefficient. The whole results were significantlystatical (p <0.05). Conclusion: While this classification provides a detailed description of meniscal lesions, the intraobserver reliability did not reach the optimum values obtained despite having on average a moderate agreement. However interobserver reliability results showed on average 70% of agreement (good agreement), which can affirm that the agreement and interobserver reliability is acceptable.

ObjectiveTo evaluate the inter-rater and intermethod correlation (reliability between MRI and arthroscopy) of knee for findings of meniscus tears using International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine (ISAKOS) classification on both 1.5 and 3.0 T images.Methods81 knees were evaluated in 69 patients aged 30.0±12.6 years (mean±SD). Consecutive arthroscopy-proven meniscal tears were evaluated by two board-certified radiologists on MRI and two sports surgeons on arthroscopies. The surgically validated ISAKOS classification of meniscal tears was used to describe medial meniscus (MM) and lateral meniscus (LM) tears on MRI and re-evaluation of images from completed arthroscopies. Prevalence-adjusted bias-adjusted kappa (PABAK), t-tests and intraclass correlation coefficient (ICC) were calculated.ResultsFor LM on 1.5 T, the agreements for location, depth, tear length and pattern were good to excellent in all categories except fair for tissue quality (PABAK=0.35–0.41) and zone 2 (PABAK=0.35) identification. For MM, the agreements were good to excellent in all except moderate for tissue quality (PABAK=0.6) and zone 1 and 3 (PABAK=0.40–0.47), and fair for zone 2 identification (PABAK=0.27). Similar results were seen on 3 T with improved LM zonal identification (PABAK=0.52–0.90) and better correlation of tear lengths, which were different on 1.5 T vs 3.0 T (p=0.01–0.03). For 1.5 T cases, both MM and LM tear lengths were larger on MRI versus arthroscopy (MM, p=0.004; LM, p=0.095). For 3 T, the MM tear lengths were larger on MRI versus arthroscopy (p=0.001).ConclusionISAKOS classification of meniscal tears on both 1.5 and 3.0 T MRI provides satisfactory inter-rater and intermethod reliability for use in clinical practice. Level of evidence: IV.

ObjectivesThe number of abstracts presented at the biennial International Society of Arthroscopy, Knee Surgery, and Orthopaedic Sports Medicine (ISAKOS) Congress has grown exponentially since its inaugural meeting in 1997. Despite this, publication rates of abstracts presented at the Congress have not been studied since 1999 where publication rates were found to be 39%. The primary objective of the current study was to provide an update on rates of publication and examine factors associated with publication.MethodsAll abstracts presented at the 2013 ISAKOS Congress were obtained from the official meeting website. Searches for subsequent publications were conducted using the MEDLINE, EMBASE and Google Scholar by two independent reviewers. Data collected included presentation type (ie, podium or poster), publication status (yes or no), study results (positive or negative), date of publication, journal name, and whether there were discrepancies between abstract and publication.ResultsA total of 746 abstracts were presented at the 2013 ISAKOS Congress. There were 413 (55.4%) abstracts that were published in peer-reviewed journals by the end of 2018 with a mean time to publication of 593 days. Podium presentations were significantly more likely to be published than poster presentations with publication rates of 61.0% and 52.5%, respectively (p<0.03). Abstracts with positive results were significantly more likely to be published than those with negative results with publication rates of 60.8% and 48.5%, respectively (p<0.001). Discrepancies from congress abstract to eventual publication were noted in 17% of studies.ConclusionPublication rates of abstracts presented at the ISAKOS Congress have improved dramatically since last studied in 1999 and are comparable to other prominent orthopaedic and sport medicine conferences. Podium presentations and abstracts with positive findings were more likely to be published. Approximately, one in five abstracts were found to have discrepancies between the abstract presented and subsequent publication.
