Fig. 1 Concurrent associations between category of body mass index and prevalence of medial tibiofemoral cartilage defects at each phase in (A) offspring; (B) controls. The bars represent prevalence of medial tibiofemoral cartilage defects in normal, overweight and obese group (Normal: body mass index < 25; Overweight: 25 ≤ body mass index < 30; Obesity: body mass index ≥ 30). P for trend determined by Kruskal–Wallis test.

Fig. 2 Interaction between weight and time on lateral knee cartilage volume in offspring. There was a significant interaction between weight and time on lateral knee cartilage volume. The effect of increasing weight on lateral knee cartilage volume becomes more negative over time. The model adjusted for common covariates including age, sex, height, smoking, knee injury, radiographic knee OA, bone size and cartilage defects.

Fig. S1Increase in medial tibiofemoral cartilage defects among those with weight loss, weight stable and weight gain over 10 years. An increase in medial tibiofemoral cartilage defect was defined as an increase of one or greater. Weight loss, weight stable and weight gain were defined as those who lost relative weight change of 5% or greater, those who gained or lost less 5% and those who gained 5%. P for trend determined by Kruskal–Wallis test.
