ABSTRACT
PURPOSE:
Purpose of this study was to establish and validate an MRI-associated classification to graduate postoperative results of MPFL reconstructions.METHODS:
30 autologous MPFL reconstructions of 28 patients were evaluated by two independent raters using MRI. All grafts were assigned to a novel graduation system respecting the graft's anchoring insertions, its MRI signal appearance, continuity and tension and the differentiation relating to the surrounding soft tissue.RESULTS:
All grafts could reliably be assigned to one of the subgroups by both raters. 86.6 % of the grafts could be classified A1 or B1, reflecting a correct positioning and a low to intermediate signal intensity. Only one graft had to be classified C3 (malpositioned, elongated).CONCLUSION:
We were able to establish and validate an MRI-associated classification to graduate the postoperative outcome after MPFL reconstructions. Foresighted, the presented classification might support further decision making in case of unsatisfying postoperative results.Palavras-chave
