Abstract
Anterior cruciate ligament (ACL) is considered as an intra-capsular extra-synovial ligament, primarily responsible for resisting anterior displacement of the tibia on flexion and extension. Magnetic resonance imagining (MRI) has been applied to musculoskeletal patho-anatomy and has been shown to be an effective tool for definition and characterization of knee pathology, regarding the knees subjected to MRI examination, measurement was done for length from femoral to tibial attachment site and thickness at the mid-portion. Comparison between the data obtained in the present study with data obtained from Kowen results there is variable length and thickness. Concluded that for the anterior cruciate ligament the length and thickness of the native ACL played an important role for choosing the type of graft and for the preparation of the graft and dimensions of the native ACL have to be considered in graft selection for anatomic ACL reconstruction.
Highlights
IntroductionAnterior cruciate ligament (ACL) has two identifiable bands, the antero-medial band (AMB) and the poster-olateral band (PLB) according to their insertion on the tibial spine (1)Anatomy is the basis of orthopedic surgery; so the anterior cruciate ligament reconstruction was governed by this concept so when native anatomy was closely restored; superior outcome can be achieved (2).Restoration of the knee kinematics, rotational stability with native ligament orientation, origin and insertion depended on anatomic anterior cruciate ligament reconstruction, and their surgical techniques must be correspondingly evolved to achieve these goals (3).In anterior cruciate ligament reconstruction orthopedic surgeons prefer to use fixed graft length and thickness, so due to the individual variation of the structure of the patient knee, failure of reconstruction was liable to occur (4); so the aim of this work was to achieve Magnetic resonance imagining (MRI) description of the
The anterior cruciate ligament length and thickness obtained from the Magnetic resonance imagining (MRI) (T2MRWI) of the knee sagittal plane and calculated by certain measurement tools built in the system of the machine, the minimum length of Regarding thickness of Anterior cruciate ligament (ACL), it was found minimum thickness was 0.5 cm (Fig.4) and the maximum thickness was 1.2 cm (Fig.5) while the mean thickness was 0.8 cm
Radiological ACL thickness measurement showed that the mean thickness was 0.8 cm
