Subgroup Analysis for the Meniscochondral Unit: MM-Preserved vs MM-Meniscectomy Group ^a

	T2 Relaxation Time, milliseconds
First vs second MRI, Δ	MM-Preserved (n = 20 knees) b	MM-Meniscectomy (n = 16 knees)	P
MFC	20.0 ± 12.6	15.9 ± 10.7	.054
MTP	4.8 ± 1.7	4.91 ± 1.1	.980
LFC	-1.6 ± 4.9	-1.9 ± 3.2	.649
LTP	1.0 ± 1.1	0.90 ± 1.9	.096
Patella	2.4 ± 1.1	2.7 ± 0.9	.072
TG	1.4 ± 1.4	1.3 ± 1.2	.871

^a Data are presented as mean ± SD. LFC, lateral femoral condyle; LTP, lateral tibial plateau; MFC, medial femoral condyle; MM, medial meniscus; MTP, medial tibial plateau; TG, trochlear groove.

^b The MM-preserved group included cases of intact MM without tear, small-size fraying on the inner side that required simple debridement, and repaired MM tear.
