title: Combined medial open-wedge high tibial osteotomy and modified Maquet procedure for medial compartmental osteoarthritis and patellofemoral arthritis of the knee.
abstract: OBJECTIVE
  Patellofemoral arthritis comes frequently with medial compartmental osteoarthritis. The combination of closed wedge high tibial osteotomy with tibial tuberosity anteriorization osteotomy has been introduced in several reports, but this technique is a technically demanding procedure and the outcomes of this technique show variable results. This article describes a novel osteotomy technique that combines medial open-wedge high tibial osteotomy (HTO) and tibial tuberosity anteriorization osteotomy (TTAO) for medial compartmental osteoarthritis and patellofemoral arthritis of the knee.
  
  
  METHODS
  Twelve knees in 10 patients who were diagnosed with combined medial compartmental osteoarthritis with patellofemoral compartmental arthritis were treated with the combination of medial open-wedge HTO and TTAO and were followed up for more than 1 year. We evaluated the patients with the Lysholm functional questionnaires, the hospital for special surgery score (HSS), and the international knee documentation committee (IKDC) criteria (mean follow-up, 14.8 months).
  
  
  RESULTS
  Union was achieved in all cases within 12 weeks. The mean Lysholm score increased from 42 preoperatively to 82.5 postoperatively (p < 0.001), the HSS increased from 57.5 preoperatively to 83 postoperatively (p < 0.001), and the IKDC score increased from 51 preoperatively to 82 postoperatively (p < 0.001). There were no other complications, such as iatrogenic fractures, nonunion, wound problem, collapse or loss of correction, and so on.
  
  
  CONCLUSIONS
  The combination of medial open-wedge HTO and modified Maquet procedure (TTAO) is considered to be an effective treatment modality for medial and patellofemoral compartmental osteoarthritis. This technique could, therefore, constantly provide a minimally invasive, precise correction of the deformity and a firm fixation that is enough to allow early rehabilitation.
