Distal Femoral Osteotomy Plate

At the most recent follow-up go to at 2 years after surgical procedure, with respect to scientific scores, each the Knee harm and Osteoarthritis Outcome Score and International Knee Documentation Committee subjective rating improved from 318 to 447 and 52 to 86, respectively. The KOOS confirmed that there was a major improvement in signs, ache, sports activities, and high quality of life. As with all surgical procedures, distal femoral osteotomy could also be associated with certain problems such as an infection, blood clots, delayed or nonunion of the bone and accidents to the encompassing blood vessels. The DFOS system contains implants to right a number of distal femoral situations, similar to flexion contractures and varus/valgus deformities. The instrumentation includes a pin information and minimize guides to assist with extra exact osteotomies and implant placement. Regarding the side, thirteen patients underwent left femur osteotomies, 12 underwent proper femur osteotomies, and 1 affected person underwent a bilateral osteotomy, totaling 27 distal femoral osteotomies.

As a part of the planning for a distal femoral osteotomy, we wish to put most of our patients right into a lateral compartment unloader brace. These braces help push the burden in direction of the within of the knee, and by doing so, they might help serve as an excellent display to find out if a patient would profit from a distal femoral osteotomy. In our palms, nearly all patients who profit from the use of a lateral unloader brace do very properly with a later performed distal femoral osteotomy and are in a position to correct the knock knee situation. Examining each the mechanical and anatomic axes is an important consideration earlier than surgical procedure.


Excluded had been patients requiring simultaneous multilevel osteotomies or these with incomplete observe up. Varus malalignment has been recognized as a threat issue for the incidence and development of medial osteoarthritis . Deformity correction with osteotomies close to the knee joint is due to this fact an important therapeutic intervention, which can stop or delay the need for joint alternative even in circumstances of extreme cartilage injury impartial of affected person age .

Thromboembolic prophylaxis is supplied based mostly on preoperative threat factors. The affected person is restricted to partial weight bearing for 6 weeks, adopted by progressive weight bearing thereafter. Closed-chain strengthening and low-influence, aerobic exercises are permitted according to the affected person’s signs. Sport-specific training and progressive influence loading actions begin when deemed applicable. Full-length standing radiographs are obtained to verify correction of deformity at 3 months postoperatively. Intraoperative fluoroscopic imaging is used to confirm adequate correction and plate-screw assemble on the lateral femoral cortex.

The DFO may be carried out concomitantly with other joint-preserving procedures together with cartilage restoration procedures and/or meniscal transplantation. Given the quality of knee arthroplasty techniques and implants, DFO has turn into mostly used for joint preservation within the younger affected person with the goal to protect the native knee joint and postpone or avoid whole knee arthroplasty. An 18-year-old male suffered a valgus damage to the right knee due to a fall during a bigfoot race he took half in when he was 15 years old.

Osteotomies For The Knee: Indications, Leading Edge Method And Outcomes

The success charges for lateral meniscal transplants and cartilage resurfacing procedures are much much less if the valgus alignment isn’t corrected with the surgical process . Overall, there is a high reoperation price in sufferers with DFOs, commonly due to the necessity for hardware elimination or, at later time points, conversion to total knee arthroplasty. In this inhabitants, the speed of conversion to arthroplasty will doubtless be significantly lowered. Cameron et al.7 reported a 92% survival price at midterm of their collection of sufferers undergoing lateral opening-wedge osteotomy for joint preservation, which was significantly better than results documented in sufferers undergoing osteotomy for lateral compartment arthritis. An osteotomy is a surgical process that entails chopping and reshaping of a bone.

As test of significance, a two-sided Wilcoxon take a look at for dependent groups was performed (SPSS model 25, SPSS Inc., Chicago/Illinois, USA) to evaluate changes in radiological and scientific parameters earlier than and after surgical procedure. Subgroup variations (oHTO vs. cDFO) were calculated with the Mann-Whitney U test. In the first 2 weeks after the operation patients should goal to be at house not doing a lot and resting. You will be discharged from hospital with the cuff a part of the Cryocuff gadget which when filled with water could be frozen and refrozen in the freezer. Please alternate this with other related gadgets and even frozen peas but remember to put a tea towel or related between the pores and skin and the frozen device.

Bony fusion was achieved six months after surgery, and he might play a number of sports activities activity. In varus deformities, osteotomies have been normally carried out in the tibia, with valgus deformities predominantly handled with femoral procedures. However, it has become widespread apply to carry out a deformity evaluation utilizing an extended standing radiograph to find out the origin of deformity previous to surgical procedure , since varus deformities can be localized either in the tibia or in the femur . In the case of femoral malalignment, a excessive tibial osteotomy ends in a pathological indirect knee joint line with increased shear forces and vice versa in the case of a tibial malalignment and femoral correction . Clinical and biomechanical studies point out that if the postoperative knee joint line just isn’t physiologically aligned, this results in a poor result . In common, most U.S. surgeons carry out a gap wedge distal femoral osteotomy to realign the knee.

A ruler is used to verify the osteotomy size primarily based on preoperative calculations. Posteroanterior fluoroscopic picture of wires placed to information the osteotomy, with medial on the right side and lateral on the left aspect of the picture. After completion of the concomitant procedures, consideration is turned to the DFO. An incision is made on the distal anteromedial facet of the femur from eight cm proximal to the patella to the center third of the patella . An incision must be made to facilitate use in future arthroplasty if needed.

At Neosteo we imagine that, given value efficient implant know-how and improved implant design, more clinicians will integrate our solutions into their practice and help patient to get well early mobility. The new technology of implants developed by Neosteo permits a direct weight bearing and a fast return of the mobility of the patient. Developed in cooperation with the medical career actors, it permits the medical team to save lots of surgical time and facilitates its handling.
