Vascularization of the Pes Anserinus Superficialis

Abstract

IntroductionThe aim of this study was to evaluate the vascularization of the superficial pes anserinus and its inserting tendons with regard to its potential use as a vascularized graft for the reconstruction of the anterior cruciate ligament.MethodsTwelve fresh cadaveric knees were used in this study. The inferior medial genicular artery was identified at its origin from the popliteal artery and incised to be perfused with a methylene blue solution. Its intra‐ and peritendinous course was evaluated macroscopically and histologically.ResultsThis study proved that the superficial pes anserinus is a highly vascularized structure. The vascularization is potentially able to supply the inserting tendons of the semitendinous and gracilis muscles retrogradely.ConclusionThe results of this study indicate that the option of a pediculated cruciate ligament reconstruction with both tendons of the semitendinous and gracilis muscles inserting at the superficial pes anserinus is theoretically possible. A pediculated reconstruction of the anterior cruciate ligament could decrease postoperative morbidity of the transplant and therefore enshorten the vulnerable healing period after surgery.Grant Funding Source: N/A
