Morphometry of Posterior Cruciate Ligament in Knee joint - A Cadaveric Study
1Department of Anatomy, All India Institute of Medical Sciences AIIMS Jodhpur.
Objectives:
Surgical repair of severely injured posterior cruciate ligament is mandatory. Therefore, the anatomical features of the PCL and its two bundles description help to define the appropriate size of the allograft for excellent results in reconstruction surgeries.
Material And Methods:
Fifty knees were dissected from twenty-five fresh human cadavers (15 male and 10 female) of donors used for teaching purpose. The length and footprint area of PCL and patellar tendon length were measured, and determined the range of normality according to sex and height.
Results:
The average lengths of the PCL's Antero-medial (AM) and posterolateral (PL) bundle were 35. 52 ± 0.66 mm and 32.76 ± 0.64mm, respectively in male and 35.37 ± 0.07 & 32.58 ± 0.61mm in female. The femoral footprint of PCL was 133.10 ± 0.7 mm2 in male and 133.05 ± 0.7 mm2 in female observed, while the tibial footprint 132.21± 1.02 mm2 in male and 132.42 ± 0.8 mm2 in female was observed.
Conclusion:
The AM and PL bundle lengths were higher in males than females. There was a strong correlation between height and length of ligaments but no correlation with age.
