Distal Femoral Osteotomy Surgery Wayne, Nj

All of the sufferers had their medical information and imaging exams reviewed to judge the diploma of correction and their current state. In contrast to the HTO, very little medical information exist on lateral distal femoral osteotomies in circumstances of varus deformities. At the distal femur, a closed wedge procedure is really helpful as a result of frequent instability in femoral open wedge osteotomies . There exist only 2 studies reporting on lateral distal closing wedge femoral osteotomies, covering a total of only 19 circumstances .

Mr Dawson has carried out over forty of these procedures with excellent outcomes from longterm patient follow up. Realigning the limb on the stage when there is only osteoarthritis in one compartment is assumed to dramatically slow and in some cases halt the spread of osteoarthritis all through the rest of the knee joint. It is a helpful different for sufferers who are still too young or active to contemplate a joint substitute. Realigning the leg helps to take the pressure off the diseased lateral compartment of the knee and relieve pain. Patients who are born with valgus knees usually tend to get lateral compartment osteoarthritis. This is as a result of the weight of their body primarily passes via the lateral compartment of the knee quite than spreading the load evenly between the entire gliding surface of the knee.

Lateral inaccuracy of DFO might be produced by the same purpose and because of the tension of the gastrocnemius muscle on the distal femur. The tibial slope influences the coronal alignment in lengthy standing radiographs . Sagittal adjustments within the distal femoral group might have influenced the coronal alignment and will count for some extent of inaccuracy. Distal femoral osteotomies are performed for patients with knock knee alignment, which we name valgus alignment.

  • The medial-proximal tibial angle and lateral-distal femoral angle also needs to be calculated to determine the origin of the osseous deformity .
  • These marks could be approximated to keep away from iatrogenic malrotation if the lateral cortex is inadvertently fractured throughout osteotomy closure.
  • It could be seen that the overcorrections have decrease preoperative initial values and attain decrease postoperative values, most likely reflecting a extra severe cartilage damage in these patients.
  • It is a useful various for sufferers who’re still too young or lively to think about a joint substitute.
  • Coronal limb malalignment is a significant contributor to asymmetric joint wear, gait abnormalities, and the development and progression of degenerative joint illness.

Once the desired correction is obtained, the plate is then placed and secured on the lateral femoral cortex. Final anteroposterior and lateral intraoperative photographs of the distal femur are then obtained prior to formal wound closure. Coronal limb malalignment is a significant contributor to asymmetric joint put on, gait abnormalities, and the development and progression of degenerative joint illness. Osteotomies in regards to the knee had been developed to realign the mechanical axis of the limb to unload the affected compartment. Valgus malalignment is much less frequent than varus malalignment, but can contribute to a wide range of scientific situations, together with lateral compartment cartilage defects and arthritis, lateral patellofemoral instability, and medial collateral ligament laxity.

Indications For Distal Femur Osteotomy

The technique presented on this article provides a protected, reproducible method to carry out the medial closing-wedge DFO. Moreover, the pearls and pitfalls which are mentioned will allow the treating surgeon to first avoid and, when needed, tackle lots of the intraoperative problems that will happen throughout this surgical procedure. Excellent postoperative outcomes including dependable healing, improved perform, and decreased ache may be anticipated when this procedure is appropriately indicated and carried out. The lateral opening wedge distal femoral osteotomy is a reproducible method for limb alignment correction in patients with valgus malalignment. Backstein et al. reported the expected survivorship of this procedure to be greater than 80% after 10 years.6 More recent studies have shown similar outcomes.
