Cartilage worsening in whole knee (medial and lateral compartments), knees developing radiographic osteoarthritis only

Meniscal status at P-1 or surgery case	No cartilage worsening N (%)	Cartilage worsening N (%)	Adjusted odds of cartilage loss (outcome) Crude odds ratio (95% CI)^a	Adjusted odds of cartilage loss (outcome) Crude odds ratio (95% CI)^b
	N = 147	N = 162
No surgery / no meniscal damage	74 (50.3%)	67 (41.4%)	Reference	Reference
No surgery, but presence of meniscal damage (tear or maceration)	68 (46.2%)	74 (45.7%)	0.98 (0.58,1.67)	0.88 (0.51,1.51)

Logistic regression adjusted for matching criteria (radiographic OA severity defined by Kellgren-Lawrence grade of index and contralateral knee, age, gender) and BMI

Logistic regression adjusted for matching criteria (radiographic OA severity defined by Kellgren-Lawrence grade of index and contralateral knee, age, gender), BMI and prevalent MRI features (cartilage damage, effusion, synovitis, BMLs)

No data for five knees at P-1

CI confidence interval, BMI body mass index, P-1 annual visit 1 year prior to case-defining visit, BMLs bone marrow lesions
