Nonoperative Treatment and Natural History of Posterior Cruciate Ligament Injuries

Augmentation or reconstruction of PCL? A quantitative review

“…These tears, 3.4-20 % of all the injuries to the knee [10], usually occur during sport activities or following traffic accidents and falls [3]. Compared to the ACL, the PCL can heal spontaneously [17,19,24,33,36], given its abundant blood supply from the branch of the middle genicular artery, and the superficial synovial layer by which is covered [4,27]. Management is conservative in acute grade I-II isolated injuries of the PCL and in chronic asymptomatic patients [46].…”

Posterior cruciate ligament is twisted and flat structure: new prospective on anatomical morphology

“…Humphrey's ligament at femoral insertion, midsubstance and lateral meniscus insertion averaged 8.7 ± 2.3, 5.9 ± 2.1 and 6.1 ± 2.0 mm, respectively, while the thickness at each level averaged 2.0 ± 1.2, 1.6 ± 0.6 and 1.9 ± 0.6 mm. The width of the PCL at midsubstance and at medial meniscus level averaged 13.3 ± 2.0 and 11.0 ± 1.6 mm, respectively, while the thickness of the PCL averaged 5.4 ± 0.8 and and preserving proprioceptive function [32,34], but this surgery is technically demanding because remaining tissues make it difficult to understand the normal anatomy [3]. In order to achieve good surgical outcomes in remnant preserving PCL reconstruction for isolated PCL injury, a precise understanding of PCL-related anatomy including the ligaments of Humphrey and Wrisberg is crucial.…”

Surgical Reconstruction in Chronic Posterior Cruciate Ligament Injuries of the Knee

“…Clinical evidence exists that most non-operative treated posterior cruciate ligament injuries heal, provided that proper protocol is followed, the knee is kept in a brace with the tibial in reduced position and good patient compliance. 12 Most of our patient came late or were referred by other institutions after having tried conservative treatment for a period of time. In addition, there was no proper non-operative treatment protocol.…”
