Fragment size, intra\u2010articular fragment location and cartilage injury score were recorded. Presence of synovitis was retrospectively evaluated in 157 joints. Kruskal\u2013Wallis and Mann\u2013Whitney tests were used for group comparisons, and Dunn's post hoc test was applied for multiple comparisons. Linear regression analysis was used to assess strength of association between age and mean cartilage score. Univariable regression analysis was performed and variables with <jats:italic>p<\/jats:italic>\u2009<\u20090.2 were used in the final mixed\u2010effects multivariable model to which backwards stepwise selection was applied.
