TI  - Survival and functional outcome of high tibial osteotomy for medial knee 
      osteoarthritis: a 10-20-year cohort study.

AB  - BACKGROUND: The primary aim of this study was to identify independent predictors 
      of long-term survivorship after high tibial osteotomy (HTO). The secondary aims 
      were to describe the functional outcome of surviving HTO 10-20 years after 
      surgery. METHODS: A retrospective cohort of 223 HTO that were performed for the 
      treatment of medial osteoarthritis was identified. Details were recorded from the 
      patient notes. All surviving patients were contacted and asked to complete a 
      Tegner Activity Scale, Lysholm Knee Score and rate pain using the Visual Analogue 
      Scale (VAS). Survival analysis was performed, using conversion to arthroplasty as 
      the definition of failure. RESULTS: The mean age was 54 years (24-80 years). 
      There were 123 (55.2%) in males and 100 (44.8%) in females. The mean BMI was 27.2 
      (SD 3.9). Twenty (9%) patients were lost to follow-up. The mean follow-up was 12 
      (SD 4) years. Survival at 10 years was 75 and 55% at 15 years and less than 40% 
      at 20 years. Cox regression analysis demonstrated age of 50 years or more, female 
      gender and surgical technique to be significant independent predictors of 
      failure. The median Tegner score was 3 (inter-quartile range (IQR) 1-3). The mean 
      Lysholm score was 75.5 (SD 18.4). The median VAS was 5 (IQR 0-6). CONCLUSIONS: 
      The medium- to long-term survival and functional outcome after HTO was good to 
      excellent at 10-20 years of follow-up. Age, gender, surgeon and surgical 
      technique were identified as independent predictors of failure.
