Introduction: Minimally invasive surgery has improved outcomes of patients as is the case of posterior tibial tendoscopy. But sometimes certain procedures are initiated without sufficient experimental studies in animals or cadavers to provide security and traceability in the implementation of these procedures and improve the learning curve on the impact on patients. Methods: We performed a descriptive study in a group of cadaveric bodies on which we underwent the conventional technique for addressing the vision portal for the posterior tibial tendon. We evaluated whether there were injuries to important structures involved. Results: The study showed lesions in the posterior tibial muscle, artery and vein. Discussion: The results show the importance of simulation processes in anatomical pieces in special techniques like this one to allow previous training that improves the learning curve of surgeons.
