Screw sequence entails putting the distal locking screws first, then a kickstand nonlocking screw in compression mode, followed by the proximal unicortical locking screws. It is important to maintain the cortical wedge allograft at the native cortex during placement of the nonlocking compression screw so as to keep away from undercorrection of the opening osteotomy. During preoperative arthroscopy, although the anterior cruciate ligament and the lateral compartment have been normal, International Cartilage Research Society grade II to III cartilage damage was famous in the patellofemoral joint. A four–5 cm longitudinal incision was made at the lateral facet of the femur simply above the femoral epicondyle based on the biplanar technique. The TomoFix medial distal femur anatomical plate was bent in accordance with the individual’s anatomy and positioned underneath the vastus medialis muscle for osteotomy fixation . Postoperative X-ray pictures showed that the operation went nearly as deliberate with an improvement of 86 degrees in mLDFA and 177 levels in FTA.

When you come to clinic we take a full patient historical past and examination along with standing X-rays of the knee joint and the patello-femoral joint. The X-ray will often show narrowing of the joint house within the lateral compartment of the knee which means that a affected person has lateral compartment osteoarthritis. Other sufferers could have sustained an injury to the knee to provoke the damage to the cartilage in the lateral compartment.

A Dedicate Instrumentation For A Precise Surgery

We may also carry out an X-ray of the whole of each of your legs from the hip joints to the ankle joints, this permits us to rigorously examine the overall alignment of your legs. We can calculate the burden bearing axis of your leg and find out where many of the force is passing through your knee joint. Mild bone marrow edema in the lateral condyle of the femur and a high sign space suggestive of hemorrhage underneath the muscular layer are noted. At the time of the initial visit to our department, visible valgus deformity of the proper knee is famous. The oHTO group had a barely extra precise correction result, with an absolute mean deviation of 2.2° ± 0.5 from preoperative planning, compared to the cDFO group with 2.6° SD ± zero.7. Accordingly, a deviation of lower than ±3° was observed more incessantly in the oHTO group after surgical procedure (14 instances / eighty two%) than in the cDFO group (7 cases, sixty four%).

  • Given the quality of knee arthroplasty methods and implants, DFO has become mostly used for joint preservation within the younger patient with the aim to preserve the native knee joint and postpone or keep away from whole knee arthroplasty.
  • Deformity correction with osteotomies near the knee joint is therefore an necessary therapeutic intervention, which may prevent or delay the need for joint substitute even in cases of severe cartilage damage unbiased of affected person age .
  • One affected person complained of plaque-associated discomfort, requiring the removal of the device.
  • Abnormal lateral distal femoral angles are considered anything lower than eighty four degrees.
  • The most important method, due to this fact, could be the one that one’s surgeon feels most snug with performing a distal femoral osteotomy.
  • To a certain extent this mimics the results of osteotomy surgical procedure by pushing the leg into a more regular alignment and taking the pressure of the broken medial compartment.

Once the specified correction is obtained, the plate is then placed and secured on the lateral femoral cortex. Final anteroposterior and lateral intraoperative images of the distal femur are then obtained previous to formal wound closure. Coronal limb malalignment is a significant contributor to asymmetric joint wear, gait abnormalities, and the development and progression of degenerative joint disease. Osteotomies concerning the knee have been developed to realign the mechanical axis of the limb to unload the affected compartment. Valgus malalignment is much less widespread than varus malalignment, but can contribute to a wide range of medical situations, including lateral compartment cartilage defects and arthritis, lateral patellofemoral instability, and medial collateral ligament laxity.

Indications For Distal Femur Osteotomy

The method offered in this article offers a protected, reproducible method to perform the medial closing-wedge DFO. Moreover, the pearls and pitfalls that are mentioned will allow the treating surgeon to first avoid and, when necessary, handle lots of the intraoperative problems that may happen during this surgical procedure. Excellent postoperative outcomes together with reliable healing, improved operate, and decreased pain can be anticipated when this process is accurately indicated and carried out. The lateral opening wedge distal femoral osteotomy is a reproducible approach for limb alignment correction in patients with valgus malalignment. Backstein et al. reported the expected survivorship of this process to be greater than 80% after 10 years.6 More latest studies have proven comparable outcomes.
