Distal Femoral Osteotomy Plate

Usually we might want to acquire an MRI scan which is finished on a separate go to to the Radiology division. An MRI allows us to take a look at the menisci to see if they are torn and will require attention at the time of surgery. It also permits us to check that the cartilage within the medial compartment is in good condition and can face up to some extra drive passing by way of it. After your MRI scan we will bring you back to clinic to debate the results of the MRI and focus on therapy options.

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

Benefits Of Distal Femoral Osteotomy

Valgus knee alignment in excess of physiological valgus results in extreme loading of the lateral compartment, which can probably improve the chance of osteoarthritis and can place the medial knee buildings vulnerable to continual attenuation. Varus-producing distal femoral osteotomies have been proposed for correction of valgus malalignment, to alleviate rigidity on medial-sided structures, as well as to off-load the lateral compartment. A distal femoral osteotomy is a process whereby a surgical fracture is created on the end of the femur and the form of the bone is modified. The video describes our preferred technique for lateral opening wedge distal femoral osteotomy. The affected person is supine, with the operative extremity draped in a traditional sterile trend. Typically, a extra lateral skin incision is made to achieve entry to the lateral femoral cortex.

This permits to calculate the accuracy of the process with a imply deviation of 2.2° within the oHTO and a pair of.6° in dhe cDFO group on this examine cohort. Table2 describes the outcomes of the medical scores for both teams pre- and postoperatively, distinguishing between overcorrections in MPTA/mLDFA in comparison with corrections inside the regular range. It can be seen that the overcorrections have lower preoperative initial values and reach lower postoperative values, most probably reflecting a extra extreme cartilage harm in these sufferers.

Distal Femoral Osteotomy & High Tibial Osteotomy: When, Where And The Way

The average postoperative Lysholm score is reported to range between sixty nine and ninety six factors and the imply SF-36 between 73 and 89 factors . Referring to these stories, the scientific outcomes of our oHTO patients are within the higher range. Only the research by van der Woude et al. investigated the postoperative scientific end result after a cDFO thus far and reported a Lysholm rating of seventy three factors and a pain degree of 3 . In comparability, the sufferers in our cDFO group confirmed a 17-level greater Lysholm rating and a 2-point lower postoperative pain level.

The success rate of distal femoral osteotomies is felt to be about 70% to seventy five% at 10 years. The success fee also relies upon upon the quantity of arthritis of the lateral compartment, if there is a concurrent meniscal transplant or cartilage resurfacing procedure, and also if the affected person just isn’t significantly chubby . In common, sufferers who smoke usually are not candidates for a distal femoral osteotomy as a result of bone doesn’t heal very nicely in smokers and this would generally be a contraindicated surgical procedure in this circumstance. A varus-producing DFO can be an excellent possibility to enhance ache and function in patients with isolated lateral compartment illness and valgus alignment.
