This study evaluated saturated lipids and unsaturated indices in different compartments of femoral-tibial bone marrow of acute anterior cruciate ligament (ACL) injured patients and compared to healthy controls and osteoarthritic (OA) patents at 3T. There were statistically significant differences (P<0.05) of unsaturation index between LT except LF in OA patients and LT, MF, MT in ACL injured patients; statistically significant differences also existed among different compartments of femoral-tibial bone marrow at 2.03ppm for saturated lipids (P < 0.02) between these two groups. OA patients have the highest saturated lipids at 2.03ppm compared to healthy controls and ACL injured patients.
