Computer-Assisted High Tibial and Double-Level Osteotomies for Genu Varum Deformity

  title={Computer-Assisted High Tibial and Double-Level Osteotomies for Genu Varum Deformity},
  author={D. Saragaglia},
We have utilized computer navigation to perform osteotomies around the knee. The goal of this article is to present our rationale, indications, and surgical technique of computer-assisted high tibial and doublelevel osteotomies for genu varum deformity. The results are based on 2 studies: (1) a comparative cohort study of computer-assisted versus conventional high tibial osteotomy, showing a 96% reproducibility in achieving a mechanical axis of 184 T 2 degrees in the computer-navigated group… Expand


Navigated osteotomies around the knee in 170 patients with osteoarthritis secondary to genu varum.
The purpose of this article is to present the authors' surgical technique and to discuss double-level osteotomy of the femur and tibia to avoid altered joint line obliquity in genu varum deformity. Expand
Double Level Osteotomy of the Knee: A Method to Retain Joint-Line Obliquity Clinical Results
Double osteotomy is a valuable procedure for patients with such a large varus deformity that appropriate realignment and load transfer to the unaffected compartment, together with an acceptable joint-line obliquity, cannot be achieved by a single osteotomy. Expand
Ostéotomie tibiale haute de valgisation pour gonarthrose sur genu varum. A propos d'une série de 193 cas revus après 6 à 10 ans de recul.
The authors have analyzed the results of 193 tibial osteotomies with varus deviation reviewed after an average 8 year follow-up and found the height of the medial tibio-femoral space was the most important factor for the stage of development of A.O. syndrome. Expand
Proximal tibial osteotomy. A critical long-term study of eighty-seven cases.
There is a considerable risk of failure of a proximal tibial osteotomy if the alignment is not overcorrected to at least 8 degrees of valgus angulation and if the patient is substantially overweight. Expand
Tibial Osteotomy for Varus Gonarthrosis: A 10- to 21-Year Followup Study
The results of this long-term followup study show that high tibial osteotomy for varus gonarthrosis allows a long period of relief of pain, good range of motion, and function in a large number of patients. Expand
Deterioration of long-term results following high tibial osteotomy in patients under 60 years of age
Investigation of the outcome of a valgus osteotomy of the tibia in patients less than 60 years of age with arthrosis of the medial compartment and a varus angle of no more than 177.7° finds HTO results in redistribution of the main stresses towards normal levels, although normal values are never attained.

Taux de survie à long terme des ostéotomies tibiales de valgisation pour gonarthrose
A long term survival analysis of 109 out of 111 consecutive HTO patients with a minimal potential follow-up of ten years finds ideal patients for HTO, with an expected survival rate of 100 per cent after 13 years, have moderate degenerative changes and a congenital deformation superior to 5 degrees.

Medial Opening-Wedge High Tibial Osteotomy with Use of Porous Hydroxyapatite to Treat Medial Compartment Osteoarthritis of the Knee
The medial opening-wedge osteotomy of the proximal part of the tibia provided satisfactory clinical results for patients with osteoarthritis of the knee, and the usefulness of hydroxyapatite wedges as the supporting material was examined. Expand
Proximal tibial osteotomy for osteoarthritis with varus deformity. A ten to thirteen-year follow-up study.
P proximal tibial osteotomy is a very suitable operation for patients who have gonarthrosis of the medial compartment, but a rigidly standardized and precise operative technique is required as well as accurate radiographic measurements of the mechanical axis of the limb, because exact postoperative alignment is the prerequisite for the longest possible period of relief of symptoms after osteotomy.

Tibial osteotomy for osteoarthritis of the knee.
The results are presented of upper tibial osteotomy carried out in ten patients for osteoarthritis of the knee associated with lateral deformity, and in every case pain has been relieved, and recovery of movement after operation has been easy. Expand
