Distal Femoral Osteotomy Houston

No obvious ligament damage or fracture was noted on MRI and physical examination. However, he progressively turned conscious of the valgus deformity of the right knee. Finally, he couldn’t participate in a sports activity due to right knee pain. X-ray images at the age of 18 at an preliminary visit to our department confirmed extreme valgus deformity with mechanical lateral distal femoral angle of seventy one levels in contrast to left mLDFA which was 87 levels.

distal femoral osteotomy

In this setting, the distal metaphyseal screws may be placed and the bicortical proximal screw can then be used to reduce the femoral shaft to the plate, thereby lowering the displacement and compressing the osteotomy. The venous plexus at the distal aspect of the medial femur should be rigorously coagulated throughout publicity. Young patients with valgus alignment and lateral compartment illness including isolated lateral compartment arthritis, lateral meniscal deficiency, and/or focal chondral or osteochondral lateral compartment defects are wonderful candidates for a DFO. Our desire is a medial closing-wedge approach because of the inherent stability of the construct, ease of surgical method, and dependable bony healing. Concomitant joint-restoring procedures including meniscal transplantation or cartilage restoration could be carried out at the time of osteotomy or in a staged method.

When Can One Have Painful Hardware Taken Out After A Distal Femoral Osteotomy?

Although not routine, if articular or meniscal pathology is suspected following preoperative analysis, magnetic resonance imaging may be thought of. Distal femoral osteotomy is performed to appropriate knee alignment which may result in extreme loading and degeneration of 1 aspect of the knee joint. The process entails chopping of the distal femur, repositioning the bones and securing them within the proper alignment. In common, one should be between the ages of sixteen and a roughly upper age of 55 to learn from a distal femoral osteotomy. Distal femoral osteotomies are mostly carried out with chronic MCL tears or ACL tears. Patients who have a distal femoral osteotomy, which is basically a surgical fracture, need to be on crutches till the osteotomy heals sufficiently to start out weightbearing.

Otherwise, there is a risk that the hinge on the within a part of the knee may crack or the screws could break because an excessive amount of weight is being placed on them from counting on the plate and screws to carry the fracture aside quite than permitting the bone to heal. The most common kind of distal femoral osteotomy is one that includes an incision on the outside of the knee. Distal femoral medial closing-wedge osteotomy on the proper distal femur of a cadaveric specimen. The patient is positioned within the supine position, with viewing from the left side of the affected person.

Standardised Radiological And Medical Evaluation

Occasionally sufferers have harm to their articular cartilage that’s limited to the outside of the knee. When this area alone is affected then it is called lateral compartment osteoarthritis. When the cartilage in all three compartments of the knee is damaged then this is named tricompartmental osteoarthritis and this is not often appropriate for osteotomy surgical procedure. If a concomitant intra-articular procedure, corresponding to a lateral femoral condyle cartilage process is to be performed, then an extended lateral peripatellar strategy is recommended. Typically, we favor to finish concomitant procedures previous to the osteotomy; arthroscopy could also be used for diagnostic purposes as needed before proceeding . In instances of concomitant procedures, for instance, lateral femoral condyle osteochondral allograft transplantation is completed first to avoid hyperflexing the knee that could cause intraoperative lack of fixation.

The success fee of distal femoral osteotomies is felt to be about 70% to seventy five% at 10 years. The success fee additionally relies upon upon the quantity of arthritis of the lateral compartment, if there’s a concurrent meniscal transplant or cartilage resurfacing procedure, and also if the affected person just isn’t significantly obese . In common, patients who smoke aren’t candidates for a distal femoral osteotomy because bone does not heal very properly in people who smoke and this would generally be a contraindicated surgical procedure in this circumstance. A varus-producing DFO can be a wonderful choice to improve ache and function in sufferers with isolated lateral compartment disease and valgus alignment.
