title: [Proximal tibial osteotomy for osteoarthritis of the knee with varus deformity].
abstract: OBJECTIVE
  Correction of the axial malalignment to slow down wear and tear of the medial compartment of the knee in instances of medial compartment osteoarthritis with varus deformity. Return to nearly normal weight-bearing ability of the knee.
  
  
  METHODS
  Patients up to a biologic age of 65 years with medial compartment osteoarthritis with varus malalignment.
  
  
  METHODS
  Morbid obesity, circulatory disturbances, gait disorders neurologic in origin, osteoarthritis of all three compartments.
  
  
  METHODS
  1st step: oblique fibular osteotomy between proximal and middle third without internal fixation. 2nd step: anterolateral approach to the proximal tibia from distal-lateral to medial-proximal and resection of a bony wedge leaving the medial cortex intact. Internal fixation with a six-hole semitubular plate using a tensioner for compression of the fragments.
  
  
  RESULTS
  In 113 patients 121 valgus realignment tibial osteotomies for medial compartment osteoarthritis were performed by three surgeons. Minimal postoperative follow-up period 10 years. 86% of the osteotomies required no further treatment even after 10 years, a total knee replacement was done in only three patients between the 7th and 10th postoperative year.
