Anatomic reconstruction of the posteromedial corner of the knee: The Versailles Technique.

Multiligament knee injury with posteromedial laxity is serious and usually requires surgery. Reconstruction is preferable to repair.The main aim of the present study was to report clinical results and laximetry for an original posteromedial corner (PMC) allograft reconstruction technique known as The Versailles Technique. The secondary aim was to determine prognostic factors for surgery.The study hypothesis was that anatomic PMC reconstruction by tendon allograft provides satisfactory medium-term clinical and laximetric results. A retrospective study assessed postoperative clinical and laximetric results after PMC allograft reconstruction at a minimum 12 months' follow-up. Laxity was assessed on comparative bilateral stress X-rays, and functional results on the International Knee Documentation Committee (IKDC) score, the Lysholm score and the Knee injury and Osteoarthritis Outcome Score (KOOS). Twenty-six patients were included between 2013 and 2019. Mean follow-up was 27.4 ± 9 months. Mean subjective IKDC score was 69.21 ± 17.36, mean Lysholm score 77.78 ± 14.98 and mean KOOS 66.44 ± 18.52. IKDC results were 77% grade A, 22% grade B, and 0% grade C or D.Mean medial differential laxity in forced varus was 0.83 ± 1.26 mm.Mean subjective IKDC scores were poorer in Schenck KD III than KD I (p = 0.03). Functional results were comparable with acute and with chronic laxity. Age correlated inversely with median KOOS (p = 0.009). There was no correlation between postoperative radiologic laxity in forced varus and functional results. Versailles anatomic PMC allograft reconstruction for acute or chronic posteromedial knee laxity showed medium-term efficacy in restoring good objective and subjective stability. IV; retrospective observational study.
