Dual Portal Closure of Periportal Capsulotomy for Hip Arthroscopy

open access: yesArthroscopy Techniques, EarlyView.
Abstract Capsular management in hip arthroscopy is an area of ongoing research, where ease of access to the hip joint is balanced with the preservation of capsular integrity and stability. Traditional techniques such as interportal and T capsulotomies allow broad exposure but may increase the risk of postoperative instability or microinstability if not
