van Wulfften Palthe AFY, et al. - Experts evaluated the independent predictors of long-term survivorship following high tibial osteotomy (HTO). They also ascertained the functional outcome of surviving HTO 10–20 years after surgery. Using conversion to arthroplasty as the definition of failure, they performed survival analysis. Authors noted that after HTO medium- to long-term survival and functional outcome was good to excellent at 10–20 years of follow-up. The independent predictors of failure were age, gender, surgeon and surgical technique.
