Distal Femoral Osteotomy

Distal Femoral Osteotomy

Several authors have recognized a postoperative HKA of 3–5° valgus or a mechanical axis at sixty two–66% of the tibial width as optimum in medial OA . Recently studies think about the extent of medial chondromalacia and carry out an individually adjusted correction with a extra average focused range of valgus (HKA 1.7–5° or 50–65% of the total tibial plateau width), while avoiding overcorrection . A knee joint arthroscopy is recommended in the identical session, for addressing intraoperative pathologies and nice-tuning of correction, relying on the type and extent of intraarticular harm .

distal femoral osteotomy

For a medial closing wedge osteotomy, a wedge-shaped section of bone is removed, and the opening is closed by bringing the reduce ends of the bones together, thus changing the alignment of the bones. We have discovered that performing the distal femoral osteotomy and the MCL reconstruction on the identical time is successful and doesn’t require two separate reconstructions. Calculations of the precise quantity of opening that is needed using the current digital x-ray systems are very accurate. Concurrent with this, a plate and screws are placed on the skin of the knee and bone graft is positioned into the opening wedge which is created to assist with therapeutic of the hole. The wedge measurement can also be planned earlier than surgery and confirmed intraoperatively.

Dfo (distal Femoral Osteotomy)

In the case of lateral compartment osteoarthritis we carry out an osteotomy within the femur to realign the knock knee to being more straight and even barely bow legged. Patients with lateral compartment arthritis usually complain of ache and stiffness across the knee. They often level to the outer side of the knee as the main focus of their pain. The knee can swell up particularly after strenuous activity and a few sufferers will notice grinding or locking of their knee. Depending upon the degree of severity of the symptoms they might have difficulty doing their usual sporting actions such as working, or walking so far as normal. In common, sufferers who want to remain comparatively high impression, especially laborers or sufferers who are still pretty energetic, or in younger sufferers, a distal femoral osteotomy can be preferred over a complete knee alternative.

  • This article provides an in depth, step-clever methodology that allows the reproducible creation of a medial closing-wedge DFO for the valgus knee utilizing locking-plate fixation.
  • Typically, a extra lateral skin incision is made to gain access to the lateral femoral cortex.
  • Closure is then accomplished in layers with the medial patellofemoral ligament repaired if partially transected.
  • Commonly, genu valgum occurs due to femoral malalignment and should be corrected with a DFO, whereas genu varum occurs due to tibial malalignment and must be corrected with an HTO.
  • The TomoFix medial distal femur anatomical plate was bent in accordance with the individual’s anatomy and positioned under the vastus medialis muscle for osteotomy fixation .

Sports-associated injuries and motorcar accidents are at present the most common causes of harm. Proper care of those injuries includes counseling sufferers and parents regarding the longer term likelihood of progress-related issues. Among them, Salter-Harris sort II is the most typical, making up about half of growth plate fractures, whereas types IV and V are rare, accounting for just a few % . Distal femoral perichondral ring injury (SH type VI, Rang’s type VI) is a relatively rare damage and is thought to lead to a high prevalence of development issues with angular deformity . However, the timing of remedy and approaches to remedy have yet to be established.
