Medial Closing

Closure is then completed in layers with the medial patellofemoral ligament repaired if partially transected. The affected person is placed in a hinged knee brace with a gentle dressing and cooling system. Full-size radiographs are obtained at 6 weeks postoperatively to confirm correction of mechanical alignment . After the osteotomy is closed and the desired correction is obtained, the anteromedial-distal femoral locking plate is placed on the anteromedial femur within the appropriate position. There are 2 small spacers placed on the proximal and distal features of the plate. These spacers are designed to keep up periosteal vascular flow after plate fixation and improve the biological elements of the construct.

distal femoral osteotomy

Care must also be taken to obtain a perfect anteroposterior fluoroscopic view of the distal femur to make sure that angular malalignment is not created. The calculated wedge size should be equal to the space between the two units of wires. These wires also serve as a boundary to information the saw blade and be sure that over-resection does not happen. The affected person is positioned supine on a radiolucent table to permit radiographic evaluation from the hip to the ankle. The affected person undergoes preparation and draping with the decrease leg placed in a stockinet and wrapped in adherent wrap to a position just distal to the tibial tubercle.

Standardised Radiological And Clinical Assessment

This is especially related in youthful sufferers, as lifetime danger of revision surgery after knee joint replacements will increase dramatically inside this patient group . We may offer sure patients a type of knee brace often known as a lateral offloading brace to trial. To a sure extent this mimics the result of osteotomy surgical procedure by pushing the leg right into a extra regular alignment and taking the pressure of the damaged medial compartment.

  • Only TomoFix plates had been used as implants for the oHTO and the operative approach was much like Staubli et al. with biplanar slicing method .
  • Varus-producing distal femoral osteotomies have been proposed for correction of valgus malalignment, to alleviate rigidity on medial-sided structures, in addition to to off-load the lateral compartment.
  • Depending upon the diploma of severity of the signs they could have issue doing their usual sporting actions similar to operating, or strolling so far as normal.
  • After your MRI scan we will convey you again to clinic to debate the results of the MRI and talk about therapy choices.
  • In the case of lateral compartment osteoarthritis we carry out an osteotomy in the femur to realign the knock knee to being extra straight and even slightly bow legged.

This permits us to document data regarding your knee condition and leg alignment on a secure central database. Patients will periodically be emailed out observe up questionnaires to watch their progress. This database will additional our detailed understanding of osteotomy surgical procedure. Osteotomy surgical procedure is not extensively carried out within the UK, it has gone out of fashion as knee replacements became well-liked. However osteotomy surgery is still widely performed in Europe and there is a massive body of evidence to support the practice.

Plate Fixation

A medial closing wedge osteotomy is carried out on the within of the femur while a lateral opening wedge osteotomy is performed on the outside. The finest approach to determine the success price of distal femoral osteotomies is to evaluate the success price in systematic critiques in the peer-reviewed literature. In common, it is felt that distal femoral osteotomies have a hit rate of 70% to eighty% at 10 years postoperatively. Most patients who did not have success during this timeframe had been converted to a complete knee substitute. The wound is copiously irrigated with regular saline answer, and meticulous hemostasis is obtained.
