Anatomical relationships between Wrisberg meniscofemoral and posterior cruciate ligament's femoral insertions

Abstract

Objective To evaluate the frequency and morphometry of the Wrisberg's ligament and its relationships with the posterior cruciate ligament's femoral insertion. Study design Controlled laboratory study. Methods 24 unpaired knee pieces, 12 right and 12 left were submitted to a deep dissection of the Wrisberg and posterior cruciate ligaments. The pieces were photographed with a digital camera and ruler; the Image J software was used to measure the ligaments’ insertion areas, in square millimeters. Results The Wrisberg ligament was present in 91.6% of the studied pieces. In those its shape was elliptical in 12 pieces (54.54%). In 68% of the knees, the WL insertion was proximal to the medial intercondilar ridge, close to the PCL posteromedial bundle. The average area for the WL was 20.46 ± 6.12 mm 2 . This number corresponded to 23.3% of the PCL's average area. Conclusions WL ligament is a common structure in knees. There is a wide variation of its insertion area. Proportionally to the PCL's insertion area the WL ones suggests that it may contribute to the posterior stability of the knee joint.

Prevalence, Biomechanics, and Pathologies of the Meniscofemoral Ligaments: A Systematic Review

“…Following full-text review and cross-referencing, 47 studies met all criteria for inclusion and were included in the review. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] After each step of the review process, any disagreement on inclusion of a study was resolved by discussion and agreement between the two reviewers. If consensus could not be reached, then inclusion was decided by the senior author (A.C.).…”

“…6 Extensive research has detailed the position and incidence of the MFLs. [7][8][9][10][11][12][13][14][15][16][17][18][19] However, a limited number of studies have proposed theories regarding their function. [20][21][22][23][24] As their role in knee biomechanics continues to unfold, these structures have potential implications for the advancement of surgical intervention on the PCL and menisci.…”
