Abstract:

Objective To study the pinpoint of footprint during the individual in-situ reconstructing of anterior cruciate ligament(ACL). Methods The footprints of femur were detected on 15 healthy knee specimen, and 15 cases with ACL rupture and underwent ACL reconstruction procedure by navigation. The angle between the axis of ACL footprint and the shaft of femur, the distance from the center of AM to posterior margin of femoral condyle, PL to the inferior margin of cartilage were detected, both in specimen and ACL reconstruction cases. Results The angle between the axis of ACL footprint and the shaft of femur was about (18.5±2.5)° and (19.3±3.1)° for specimens and patients respectively; The distance from the AM to medial surface of lateral condyle of femur was (6.1±1.8)mm and (5.8±1.2)mm; The distance from PL to the edge of inferior cartilage was about (6.2±2.2)mm and (5.9±2.5)mm respectively; The values of parameter were different for different samples and cases. Conclusions The footprints of ACL on the femur and the tibia are variant both in specimens and patients. During in-situ ACL reconstruction procedure, individual ACL footprint measurement should be performed.
