With the patient positioned within the supine place on a radiolucent table, the articular surface was identified by palpation and radioscopy. An incision of ∼ 10 cm was carried out, extending proximally from the medial knee joint line. Next, the vastus medialis was bluntly dissected to expose the condyle and the medial femoral cortex. Thus, no neurovascular construction was exposed or put in danger during the surgical access, and the bone floor required for osteotomy was safely approached.
Smoking has a profound effect on fracture healing and we must not danger the bone not healing back collectively. Patients who’re obese typically discover their knee ache is significantly improved when they shed weight. Simple analgesia such as paracetamol along with ibuprofen can help with ache and sleep disturbance type the ache. Limb realignment also can assist relieve pain and problems arising from a patella that is not gliding normally throughout the top of the femur. This is an operation normally performed for arthritis and sometimes patella instability issues around the knee.
Commonly, genu valgum occurs due to femoral malalignment and ought to be corrected with a DFO, whereas genu varum happens due to tibial malalignment and should be corrected with an HTO. However, this generality just isn’t at all times the case—significantly in the setting of post-traumatic malalignment. Therefore, these angular measurements ought to at all times be performed during preoperative templating to make sure that an indirect joint line just isn’t iatrogenically created. In uncommon circumstances, each a DFO and an HTO may be needed to make sure a balanced osteotomy to keep up a joint line that is parallel and horizontal. In addition, the joint congruence angle could also be calculated in the setting of joint house narrowing to make sure that overcorrection doesn’t occur, given that joint area narrowing frequently is partially corrected after correction of osseous malalignment.
Our Osteotomy Plates
During a distal femoral osteotomy, the femur is lined up surgically so that the femoral axis passes via the center of the knee and pressure on the broken side of the knee joint is relieved. The first one is in patients who may have developed arthritis either from a earlier lateral meniscectomy or genetic causes and who’re found to have pretty regular cartilage in the rest of their knee, however have arthritis on the outside of their knee. At this time, a marking pen or surgical electrocautery system could also be used to mark corresponding positions on the proximal and distal osteotomy edges parallel to the femoral shaft. These marks may be approximated to avoid iatrogenic malrotation if the lateral cortex is inadvertently fractured during osteotomy closure.
The present study aims to explain the surgical approach and a case series submitted to femoral osteotomy with medial closing-wedge in a referral service, and to evaluate the current characteristics ensuing from this procedure in up to 15 years of observe-up. In all of the cases, a impartial alignment related to the anatomical axis was achieved. One affected person complained of plaque-associated discomfort, requiring the removal of the device. One patient had a superficial an infection, however no osteotomy revision was needed. Therewere no circumstances of deep venous thrombosis or of pulmonary thromboembolism. Our results point out that an appreciable proportion of varus deformities are of femoral origin and that cDFO supplies comparable radiological and medical results as oHTO.
What’s Distal Femoral Osteotomy?
The facilities of the hip and ankle are decided, and a line is then drawn from the middle of the hip joint to the center of the ankle joint. Next, tibial and femoral knee joint traces are drawn and the lateral distal femoral angle and medial proximal tibial angle are measured. In tibial deformities the new mechanical axis starts from the hip middle and in femoral deformities from the ankle middle and runs between the intercondylar tubercles. The aiming point of the brand new mechanical axis is between the medial and lateral intercondylar tubercle depending on cartilage and meniscal tears.
A diagnostic arthroscopy can be carried out to verify that there is isolated lateral compartment disease . Concomitant procedures may be carried out at this time to deal with lateral compartment chondral or meniscal disease or deficiency. Two surgical approach options can be thought of for a lateral, distal femoral osteotomy. The first is a true additional-articular approach during which a 12- to 15-cm lateral incision is made over the midline lateral femur and angulated anterior 2 cm distal to lateral epicondyle. The vastus lateralis is elevated from intermuscular septum, being careful to coagulate arterial branches of the profunda femoris. Very promising outcomes have recently been revealed by a single analysis group using patient-specific chopping guides in oHTO and oDFO .
- Routinely we then see patients at one yr publish op, to evaluate if they would profit from having the plate removed.
- These spacers are designed to take care of periosteal vascular circulate after plate fixation and enhance the organic features of the assemble.
- This will subsequently be the new mechanical axis of the whole leg (Fig. 1).
- However, the timing of remedy and approaches to therapy have but to be established.
- Dissection should be distal sufficient to have good exposure of the anteromedial condyle of the femur proximally to securely place the locking plate beneath direct visualization.
This depth must be roughly 5 to 10 mm shorter than the previously measured lengths of the wires to ensure that the lateral cortex is not violated. The saw is used to create each medial-to-lateral cuts beneath fluoroscopic steerage, and the wedge of bone ought to then be easily removed from the medial cortex, with confirmation of a whole osteotomy of the anterior and posterior cortices . Difficulty with wedge removing usually happens when the anterior or posterior margins of the wedge haven’t been fully accomplished.

A metadiaphyseal guide pin is positioned approximately 2 to 3 fingerbreadths proximal to the lateral epicondyle and aimed just proximal to the medial epicondyle to ascertain the trajectory of the osteotomy . A mark on the cortex above and under the anticipated osteotomy helps assess any potential rotation of the femur . To decrease the chance of iatrogenic neurovascular injury, the knee is then flexed to lower tension on the neurovascular bundle and increase their distance from the posterior cortex. An oscillating saw blade is used to begin the osteotomy, whereas maintaining the trajectory of the guide pin. Thin osteotomes are used to complete the reduce within 1 cm of the medial cortex (this distance is measured on a calibrated preoperative x-ray and the desired measurement marked on the osteotome). The jack opener is placed and opened, and the osteotomy is hinged fastidiously at the medial cortex slowly over time, to take advantage of the viscoelastic properties of bone.
