Purpose: To report 3 patients operated on using medial hip arthroscopic portals, describe the surgical technique and clinical outcomes.
Methods: Three medial portals were made, the first one at the posterior edge of the adductor longus muscle (posterior medial portal), the second one at the anterior (anterior medial portal) and the third at the posterior border of the adductor longus, 5 cm distal to the inguinal crease (distal posterior medial portal). The first case was an 8-year-old boy with a lytic lesion at the posteromedial region of the femoral neck suggestive of sub-acute osteomyelitis. The second patient was a 21-year-old male with a posteromedial femoral neck nidus. The third patient was a 42-year-old male with a posteromedial femoral neck cystic lesion.
Conclusions: The described portals allowed successful access to posteromedial femoral neck. There were no neurovascular lesions, infection, femoral head osteonecrosis, skin retraction or functional limitation related to the portals.
