O1272 EVALUATION OF KNEE RETINACULAR LATERAL RELEASES USING AN ARTHROSCOPIC TECHNIQUE



Abstract

Aims: Clinical and radiographic evaluation of retinacular lateral releases using an arthroscopic approach, for anterior knee pain in cases with slight patelar axial malposition Methods: Prospective study in 34 patients. Evaluation according to the Insall clinical score, patient opinion, and change in radiographic angles and index from pre-operative to post-operative. Results: Postoperative clinical score (Insall 1983): 82% excellent; 6% good; 6% poor; 6% bad. Angular values: patelar index (Cross 1976) of 7,1 and sulcus angle (Brattstrom 1964) of 139,6∞. Radiographic correction: from 15,7 to 17,9 in patello-femoral angle (Laurin 1978); from −5,6 to −5,3∞ in congruency angle (Merchant 1974); and from 1,37 to 1,12 in patello-femoral index (Laurin 1978). Conclusions: Clinical results, patient satisfaction, and radiographic correction of congruency angle, patello-femoral angle and patello-femoral index make justifiable the use of arthroscopic lateral releases in the treatment of selected cases of patello-femoral pain.
