Posterior Cruciate Ligament Rupture

Abstract The morphology and histology changes in the medial meniscus after posterior cruciate ligament (PCL) rupture are poorly understood. Forty-eight rabbits were divided into matched mode pairs; each rabbit had an experimental side, in which the PCL was transacted, and a control side. At the 4, 8, 16 and 24 weeks after the PCL transection, each of the 12 rabbits was killed. Histology was performed to detect the expression of the tissue inhibitors of metalloproteinases-1 (TIMP-1), matrix metalloproteinase (MMP)-1 and MMP-13 in the medial meniscus. We found that medial meniscus displayed significant degenerative characteristics in morphology. The histological evaluation of the degeneration found that the expression levels of TIMP-1, MMP-1 and MMP-13 in the medial meniscus were higher in the experiment side than those in the control side (P<0.05). The expression of both TIMP-1 and MMP-13 was initially elevated and then decreased. The MMP-1 expression reached its peak swiftly and then maintained a relatively high level. There were clear time-dependent degenerative changes in the histology of the medial meniscus after PCL rupture. The high expression of TIMP-1, MMP-1 and MMP-13 in the cartilage may be responsible for the degeneration, and PCL rupture may trigger meniscus degradation and ultimately osteoarthritis.

Introduction: Heterotopic ossifications (HO) are a well-recognized but infrequently encountered condition. In the lower limb, the literature commonly reports the formation of HO around the hip after surgeries. However, HO is uncommon around the knee and a rare complication after open fixation of posterior cruciate ligament (PCL) avulsion fracture. Case Report:Here, we describe a case of HO in a 42-year-old patient with multiligament injury, including PCL and arcuate ligament avulsion, partial ACL tear, and medial meniscus root tear with suspected vascular compromise. He underwent open reduction and internal fixation of PCL avulsion fracture and medial meniscus root repair after the injury. At a 6-week follow-up, a plain radiograph revealed posterior capsule HO which kept increasing over successive follow-ups compromising his knee function. The patient was not willing for any mode of intervention for the same at any given time. Conclusion:HO after open PCL avulsion fixation is an uncommon entity. This article sheds light on how open fixation of PCL bony avulsion in a multiligament injured knee could result in a HO. Keywords: Posterior cruciate ligament avulsion, multiligament injury, open fixation, suture anchor, heterotopic ossification, posterior capsule.
