Worth replacing a loss of medial meniscal tissue with a polyurethane substitute (Actifit®) when performing a valgus tibial osteotomy addition

Introduction:The addition tibial valgus osteotomy (ovat) is a common treatment of symptomatic genu varus. This frequently is accompanied by considerable loss of medial meniscal tissue. The aim was to evaluate, in the context of performing a ovat, restoring the functional impact of this lack of medial meniscal tissue with Actifit® compared with the simple meniscectomy.Material and Methods:Sixty patients with symptomatic genu varo operated with ovat were studied prospectively. In 30 patients we have left a medial meniscal defect> 25 mm (M) and in 30 a medial Actifit® was implanted(A). The evaluations were performed using Womet, IKDC, Kujala, EVA and satisfaction (0-4).Results:Both groups were statistically comparable preoperatively, including follow-up time (31.2 months; range, 24-47.5; p = 0.35). 53.4 ± 8.4 Womet improved and 42.4 ± 17.2 points in M and A (p = 0.002), improved IKDC 56.7 ± 12 and 50.3 ± 15.6 points in M and A (p = 0.107), 50.4 ± 14.7 Kujala improved to 38.9 ± 21.6 points M and A (p = 0.02) ...
