AB  - PURPOSE: To identify the arthroscopic findings associated with deterioration of 
      10-year clinical outcomes after opening-wedge high tibial osteotomy (OWHTO) in 
      patients with knee osteoarthritis. METHODS: A total of 114 consecutive knees of 
      91 patients with knee osteoarthritis who underwent OWHTO between 2007 and 2011 
      were retrospectively reviewed. Of these patients, those who underwent second-look 
      arthroscopy and were followed up for a minimum of 10 years were enrolled. The 
      Knee Society Score (KSS) and hip-knee-ankle angle were assessed. Cartilage status 
      was graded at the time of osteotomy (first look) and plate removal (second look) 
      according to the International Cartilage Repair Society (ICRS) grading system. 
      The KSS knee subscale score and function subscale score were assessed separately, 
      and on the basis of the changes in each of these scores from 1 to 10 years 
      postoperatively and the minimal clinically important difference (MCID), the 
      patients were divided into 2 groups: deteriorated (deterioration of score >/= MCID) 
      and non-deteriorated (deterioration of score < MCID). RESULTS: Sixty-nine knees 
      were included in this study. The mean knee score improved continuously from 48.7 
      +/- 11.3 preoperatively to 86.8 +/- 10.3 at 1 year (P < .001), 87.5 +/- 9.9 at 5 years 
      (P < .001), and 86.5 +/- 10.5 at 10 years (P < .001) postoperatively. The mean 
      function score also improved continuously from 62.5 +/- 12.1 preoperatively to 90.7 
      +/- 12.9 at 1 year (P < .001), 91.6 +/- 12.1 at 5 years (P < .001), and 88.5 +/- 13.1 
      at 10 years (P < .001) postoperatively. Three knees underwent conversion to total 
      knee arthroplasty within 10 years postoperatively. The deteriorated KSS group 
      showed significantly progressed ICRS grades in the lateral compartment compared 
      with the non-deteriorated KSS group. The ICRS grade in the lateral compartment at 
      second-look arthroscopy was identified as the only significant factor associated 
      with both knee score deterioration (odds ratio, 4.89; P = .03) and function score 
      deterioration (odds ratio, 3.91; P = .03) on multivariable logistic regression 
      analysis. CONCLUSIONS: The presence of cartilage degeneration of the lateral 
      compartment of the knee at second-look arthroscopy is associated with 
      deterioration of long-term clinical outcomes after OWHTO. LEVEL OF EVIDENCE: 
      Level IV, therapeutic case series.
