Description
High tibial osteotomy (HTO) represents a joint preserving procedure responsible for delaying the need for joint replacement. A deep insight into predictive demographical and radiological factors related to surgical failure might help in highlighting a surgical algorithm to select the best treatment for specific patients. The current study was aimed to evaluate demographical and radiological risk factors predictive of failure and to detect differences among two different techniques of valgus-producing HTO, closing (CW) and opening (OW) wedge. The results pointed out that high BMI, previous meniscectomy, and high KL index were significant risk factors in the overall population, while smoking, high LDFA and KL index were found significant in CW population. Previous meniscectomy was the only factor found significant in OWHTO.
