Duplex ultrasound and CT angiography of the left lower extremity revealed a 4 cm sac of pseudoaneurysm on the distal part of posterofemoral branch of deep femoral artery and a 9*10 cm haematoma on the posteromedial
part of pseudoaneurysm.
A possible explanation for this is the larger amount of dissection (crossing more anatomical layers, like the ligamentum laciniatum and the tarsal tunnel) that is required to protect the neurovascular bundle in the open posteromedial
approach as compared to the open posterolateral approach.
The popliteal artery was repaired via posteromedial
approach as shown in fig-3 harvesting reverse saphenous venous graft from contralateral leg.
1 cm shallow cup-shaped OCL was present at the posteromedial
aspect of the tibial plafond demarcated by a thin crescent-shaped hypointense T1 and T2 line with minimal marrow edema in the osteochondral fragment and surrounding medullary space.
Usually, adequate posteromedial
fragment reduction and buttress plating require a direct posteromedial
approach, or a combination with an anterolateral approach.
and posterolateral portals were created according to the technique reported by Schreiber (14) (Fig.
7] There are associated posterolateral, posteromedial
or anterolateral corner injuries and meniscal injuries.
The appendix is located posteromedial
to the caecum, but its location may be different in the presence of subserous parts.
portal was created, and the vestige of the hypoplastic PCL was debrided off its insertion point.
The distal fracture displacement were reported as either posterolateral or posteromedial
and as being either an extension or a flexion-type fracture.
Results: For both groups and in both legs, the distance reached in the medial, posteromedial
, posterior and posterolateral directions was similar and further than the other directions.
Standard anteromedial and anterolateral portals were used for anterior ankle arthroscopy (Figures 1 and 2), and posterolateral and posteromedial
portals were used for posterior an kle arthroscopy, as described by van Dijk  (Figures 3 and 4).
