Table 5.

Odds ratios (OR), 95% confidence intervals (CI), and associated p-values for variables in the loss of motion-related subsequent surgery model.

Variable	Level	OR (95% CI)	P-value
Sex	Male (reference)	-
	Female	2.49 (1.55,4.02)	<0.001
Age (years)		0.60 (0.39,0.92)	0.02
BMI		0.96 (0.73,1.25)	0.75
Baseline KOOS Symptom score		0.54 (0.39,0.76)	<0.001
Knee Effusion	No (reference)	-
	Yes	1.35 (0.86,2.12)	0.19
Concurrent meniscal repair?	No (reference)	-
	Yes	0.74 (0.41,1.33)	0.31
Graft type	Autograft - BTB (reference)	-
	Autograft - hamstring	1.08 (0.64,1.84)	0.77
	Allograft - BTB	0.83 (0.28,2.48)	0.75
	Allograft - soft tissue	1.93 (1.05,3.56)	0.03

Key: P-values less than 0.05 are bolded; Numeric variables compare the 25^th and 75^th percentiles. Key: BMI=body mass index; BTB = bone-patellar tendon-bone; KOOS=Knee injury and Osteoarthritis Outcome Score.
