The transosseous perforator veins of the knee

The perforator veins (PVs) of the knee can be responsible for reticular veins, telangiectases, and varicosities around the knee, but they are frequently underdiagnosed and missed by the phlebologists and the sonographers because of their tiny size. These PVs are frequently located around the patella and connected with transosseous perforators, well-demonstrated in the anatomical part of this work This could explain why sclerotherapy of cosmetic lesions around the knee frequently leads to poor results and recurrence. This article proposes a systematization of these atypical PVs and discusses their possible role in phleboarthrosis.
