Dfo Distal Femoral Osteotomy
After that we make a 10cm incision over the within facet of the leg just above the knee to permit us to carry out a managed osteotomy of the top part of the femur. The entire leg alignment X rays permit us to precisely calculate precisely what measurement wedge of bone to take away so as to realign the limb. Very often it may be essential to take bone graft often from the wing of the pelvis to help the therapeutic of the osteotomy. We then use a robust titanium plate and screws to hold the osteotomy website securely whereas it heals.
Lateral compartment illness mixed with valgus alignment can lead to progressive knee joint degeneration. In the symptomatic patient with isolated lateral compartment illness, a varus-producing distal femoral osteotomy can unload the diseased lateral compartment. This osteotomy could also be mixed with different cartilage or meniscal restorative techniques to optimize knee joint preservation and pain aid. The osteotomy may be carried out with a medial closing-wedge or lateral opening-wedge approach. Both strategies have been reported to improve knee-related quality of life in patients with lateral compartment disease.
The physiotherapy team will proceed to work with you as an outpatient and they present us with a report on the 6 week mark post op. We will see you in clinic on the 3 month mark and perform repeat x rays of the limb to assess the correction. Routinely we then see patients at one 12 months post op, to evaluate if they might benefit from having the plate eliminated. After theatre the patient will go to the recovery room and we will remove the bandages across the knee and apply a cryocuff to chill the knee and cut back swelling and pain. We use a particular mixture of medicines before throughout and after the surgical procedure to minimise the amount of bleeding, swelling and ache from the operation. Extra medications might be obtainable on the chart to request if you feel pain or nausea.
Distal femoral osteotomy is indicated to appropriate deformities and malalignments similar to valgus knee, a deformity the place the knee angles out from the middle of the body. It can also be performed to treat osteoarthritis in younger lively patients contraindicated for joint substitute. Several HTO research agree with a ± three° deviation from planning as an appropriate vary . Reported outcomes are very variable with 23 to ninety two% being in the outlined target range .
Other than concurrently either including bone or taking out bone, there is probably not an enormous distinction between both approach. The most necessary approach, therefore, can be the one that one’s surgeon feels most comfy with performing a distal femoral osteotomy. For sufferers with ACL deficiencies, if they’ve vital arthritis of their lateral compartment with valgus alignment, then a concurrent ACL reconstruction with a distal femoral osteotomy could also be indicated. In addition, there are some patients who might have a cartilage substitute surgery and/or a lateral meniscal transplant with their ACL reconstructions. The subsequent most common indication for a distal femoral osteotomy is when a patient is knock knee and wishes a lateral meniscal transplant and/or a cartilage resurfacing procedure of the surface compartment of their knee.
The vastus lateralis is fastidiously lifted up from intermuscular septum and the distal medial facet of the femoral shaft is identified. This is a vital step within the exposure as important bleeding could be encountered if not appropriately coagulated, which may trigger vital issues to the limb, in addition to affect visualization during the process. The authors’ most well-liked method for a distal femoral opening-wedge osteotomy is described below with an accompanying video demonstration . Distal femoral progress plate fractures are not benign fractures and should not be treated as such. Patients and their families should be educated and warned about the potentialities of complications, which aren’t restricted to progress disturbance alone.

Patients might be seen in our pre-assessment clinic the place an anaesthetic verify up shall be performed. They may even see one of the surgical team earlier than the day of surgery to undergo the consent kind. The cut within the distal femur is made using an oscillating saw and a predetermined part of bone is eliminated. • Undercorrection by not sustaining the cortical wedge allograft on the native cortex during placement of the nonlocking compression screw opening osteotomy.
The arthrotomy ought to be made as far proximal as possible to facilitate proximal hardware placement and lessen tension on the medially subluxed patella during access to the intra-articular lateral femoral condyle. The intermuscular septum is launched and a radiolucent retractor so as placed to protect the tibial nerve and popliteal artery . The patient is positioned in the supine position with the sterile subject exposing the whole limb together with the iliac crest so that the axis of the limb may be assessed intraoperatively. Patient place must facilitate enough intraoperative imaging studies; thus, the operative limb could also be raised on a bump or the contralateral limb may be lowered.
After the osteotomy is situated on paper or on a digital platform, the proximal part of the femur/distal a part of the tibia is moved to the final location of the femoral head/ankle middle located on the mechanical axis. In bifocal deformities a vertical line is drawn such that it types an 87-diploma lateral angle with the distal femoral joint line. This will subsequently be the brand new mechanical axis of the entire leg (Fig. 1).
