ABSTRACT

Introduction. Until the beginning of 1993, our experience in treating rotula instability: relapsing luxations and subluxations, had been through open procedures: proximal or distal alignment, or combining them into each other. From July 1993, we began the rotula instability management through the release of the lateral retinaculum and median retinaculum fold, assisted by arthroscopy. Material and methods. We reviewed 24 cases of rotula instability operated between 1993 and December 1999 with a minimum follow-up period of three years and six months, and a maximum of nine years and three months in postoperative. We describe the arthroscopy surgical procedure, which combines: the release of the lateral retinaculum, and the fold of the proximal-median retinaculum. Our evaluation parameter was whether the rotula stabilization was achieved. Results. In relation to the presence of rotula luxation or subluxation events subsequent to the surgery, the rotula stabilization was achieved in 22 cases (91.6%), with the only presence of complications as two cases of luxation: one of them in a young patient, who presented an acute initial luxation, and other patient presenting with recurrent bilateral luxation. We also performed a review on the postoperative management. Discussion. Rotula instability, in its diverse clinical presentations, has been a point of controversy in relation to the best treating method, with the obvious aim of avoiding new instability events, as well as finally achieving an asymptomatic knee. When comparing the positive results by the Small’s least-invasive technique, 1993 (92.5%).
