Dewilde et al. Preoperatively, the amount of correction was estimated using a simplified calculation of 1 mm of linear correction at the osteotomy site to 1 of correction of axial alignment. I have looked many times for answers on my tibial tubercle osteotomy and never found any as detailed as i needed. 2. After fluoroscopic confirmation of correct guide pin placement, an osteotomy was performed using an oscillating saw and sharp osteotomies, taking care to maintain approximately 1 cm of medial bone bridge for osteotomy stability. Epub 2020 Jul 20. 1 Even with evolving fixation strategies and implants, . 4. Distally the coupler was mated to a DFR in the usual fashion . Generally, a hinge of 8-15 mm is made to improve the alignment and offset potential issues of the knee. Usually bone graft, plates, and screws are used to hold open the distal femoral osteotomy. Seven knees in six patients were lost to followup before 2 years and were excluded. 2022 May;18(2):297-306. doi: 10.1177/15563316211051295. Methods: This surgery aims to reduce lateral compartment overload and to prevent knee osteoarthritis (OA) progression [ 1 ]. The fascia over the vastus medialis is incised and retracted laterally and anteriorly to expose the femoral shaft. Pain requiring hardware removal was the most common complication in both techniques, while long-term survivability was found to be a function of follow-up and not surgical technique. Distal femoral varus osteotomy for painful genu valgum. Five-year survivorship was 74% in the arthritis group and 92% in the joint preservation group with conversion to arthroplasty as the endpoint. This estimate was adjusted intraoperatively based on both clinical and radiographic analysis. [17] recently reported on the outcome of 45 knees treated with medial closing-wedge distal femoral osteotomy for lateral compartment arthritis. Careful selection of each surgical candidate is necessary to ensure maximum benefit. We only report on 21 of 31 knees in regard to alignment correction, because full-length radiographs were not available on all patients. Distal femoral varus osteotomy may be used to treat valgus knee malalignment or to protect a knee compartment in which cartilage restoration surgery (such as osteochondral or meni 4010 W. 65th St. I am so glad I did! This website uses cookies. Characteristics of the arthritis and the joint preservation groups. Hardware prominence and removal rates have been shown to be approximately 2.5 times greater in the LOW group. The https:// ensures that you are connecting to the Epub 2021 Oct 27. The surgical goal was to restore the mechanical alignment to neutral with the mechanical axis through the center of the knee. Medial closing-wedge osteotomy has demonstrated good success in treatment of osteoarthritis in published series, but few studies have evaluated distal femoral lateral opening-wedge osteotomy in terms of correction of deformity, pain and function, and survivorship. These studies report the correction of deformity and the pain and function of small cohorts of patients undergoing a medial closing-wedge distal femoral osteotomy for treatment of lateral compartment arthritis. DFO to correct genu valgum has traditionally been completed through a medial closing wedge distal femoral osteotomy (MCWDFO). Joint preservation patients satisfied the criteria for osteotomy as described but were younger patients with a mean age of 26 years and were motivated to maintain an active lifestyle. Varus-producing distal femoral osteotomy has been described as a treatment option for symptomatic lateral compartment osteoarthritis in active individuals with genu valgum. MeSH official website and that any information you provide is encrypted Federal government websites often end in .gov or .mil. This is the first study to our knowledge to look at both of these groups of patients undergoing the same procedure by the same surgeon. OSferions micro- and macroporous structure allows it to be resorbed and replaced by bone during the healing process. The femur is cut with surgical instruments to about 1 cm away from the medial edge of the femur, commonly at a 45-degree angle and angling towards the adductor tubercle, and the bone is then slowly opened up to the point where the weightbearing goes through the center of the knee. Our retrospective study aims to evaluate the outcomes and analyze survivorship of the distal femoral osteotomy until eventual conversion to knee arthroplasty.

Patients who had any symptoms in the medial or patellofemoral compartment in addition to the lateral compartment were not considered for osteotomy. Survivorship at 74 months with the endpoint of TKA was 83%. [16] reported on 21 medial closing-wedge osteotomies in 19 patients with a mean age of 57 years at 2- to 12-year followup. The system is designed to correct valgus malalignment through the knee joint and is carried out through a distal lateral femoral approach. For the meniscus and cartilage transplant patients realigning the knee can increase the healing of the transplant and improve survival. Results: Of the 71 patients who followed -up beyond six months post-operatively, seven eventually converted to total knee arthroplasty (9.9%). The workup of this includes long leg x-rays to confirm that the patient is malaligned and does have valgus alignment, one has an arthroscopic surgery or an MRI to confirm that the cartilage on the inside part of the knee is fairly intact, as well as the majority of the medial meniscus and that one has intact ligaments or plan to reconstruct the ligaments either concurrently or thereafter the osteotomy. I was hit by a car on my bicycle near Horsetooth Reservoir in CO. Achieving our desired correction of 3 from neutral alignment was clinically difficult. Osteotomies around the knee are well-recognized treatments for unloading the affected compartment in cases of lower limb malalignment. We achieved our goal of within 3 of mechanical neutral alignment in seven of 15 patients in the arthritis group and three of six patients in the joint preservation group who had followup mechanical axis radiographs. The third most common reason for a distal femoral osteotomy is in patients who have a chronic MCL tear who are in valgus alignment. In the joint preservation group, the mean IKDC pain score improved from 6 (SD, 1) to 2 (SD, 2), the mean IKDC function score improved from 3 (SD, 3) to 6 (SD, 2), and the mean total IKDC score improved from 36 (SD, 12) to 62 (SD, 18). The most important technique, therefore, would be the one that ones surgeon feels most comfortable with performing a distal femoral osteotomy. The reoperation rate and survivorship were 53% and 74%, respectively, for the arthritis group and 50% and 92%, respectively, for the joint preservation group. However, osteoarthritis continues to progress and multiple arthroscopic or open procedures may be required despite a successful osteotomy. Pain and function were measured preoperatively and postoperatively using the International Knee Documentation Committee (IKDC) score. Thin and low profile to prevent overlying soft-tissue irritation, the titanium plate is attached to bone using 4.5 mm and 6.5 mm cancellous screws that seat flush to the plate surface. Its combination with various cartilage repair procedures has been shown to further improve outcomes. This surgery is very successful in these cases and can dramatically improve success of these procedures if done in conjunction. HHS Vulnerability Disclosure, Help Additionally, compared to knee replacement patients are allowed to participate in much more rigorous activities. The aim of this study was to report the occurrence of . In general, this is a successful procedure if done for the right indications. Dr. Robert F. LaPrade operated on my right knee in May of 2010. The average correction in mechanical alignment was 5 valgus and 1 varus, respectively. Thank you, Dr. LaPrade, for treating me with the care, focus, and expertise as if I was an Olympic athlete!- From your 63 year old very appreciative patent ~. Means and SDs were calculated to describe IKDC pain, function, and total scores preoperatively and at latest followup. Besides, it is still controversial whether patellofemoral arthritis should be considered as a contraindication to performing a DFO, as well as in HTO. Ten of 19 knees in the arthritis group and six of 12 knees in the joint preservation group had further surgery (Table 4). Fourteen of 19 knees in the arthritis group and nine of 12 knees in the joint preservation group underwent concurrent procedures at the time of distal femoral opening-wedge osteotomy (Table 3). Joint line convergence angle (JLCA) = 5, mechanical lateral distal femoral angle (mLDFA) = 84. b Preoperative planning of opening-wedge (DFO). Please enable it to take advantage of the complete set of features! There are few papers in the literature describing the outcomes of distal femoral osteotomy (DFO), as compared with the studies reporting on high tibial osteotomy (HTO), probably because valgus malalignment is less common than the varus one. 20. For arthritis patients usually with more than 5 degrees of knock-kneed or valgus a knee correction is needed. HSS J. 2021 Jul;34(8):816-821. doi: 10.1055/s-0039-3400742. Matsushita T, Mori A, Watanabe S, Kataoka K, Oka S, Nishida K, Nagai K, Matsumoto T, Hoshino Y, Kuroda R. Arch Orthop Trauma Surg. Terry GC, Cimino PM. Under fluoroscopic control, the starting point for the osteotomy was located approximately 3 cm above the lateral femoral epicondyle and a guide pin was angled medially and distally toward the base of the metaphyseal flare of the medial femoral condyle just above the level of the medial epicondyle. SPSS Version 13.0 (IBM Corporation, Armonk, NY, USA) was used for all statistical analyses. At an average 99-month followup, 83% were reported as satisfactory and three were converted to TKA. The study population was stratified into two groups based on reason for osteotomy: patients with isolated symptomatic lateral compartment arthritis (arthritis group; 19 knees [61%]) and patients who underwent joint preservation procedures including osteochondral allograft transplantation or meniscal allograft transplantation (joint preservation group; 12 knees [39%]). Limb alignment was checked fluoroscopically and clinically. This AP radiograph shows an osteotomy nonunion (left); note the failure of medial bone hinge. I can run, bike, & climb mountains. HHS Vulnerability Disclosure, Help Osteotomies around the knee are well-recognized treatments for unloading the affected compartment in cases of lower limb malalignment. 2016 Jun 6;4(6):2325967116649901. doi: 10.1177/2325967116649901. The chamfered wedge design of the OSferion implants corresponds to the shape of the osteotomy and can be easily trimmed to size using a rongeur. The next most common indication for a distal femoral osteotomy is when a patient is knock knee and needs a lateral meniscal transplant and/or a cartilage resurfacing procedure of the outside (lateral) compartment of their knee. Preoperatively, all patients underwent complete radiographic evaluation including full-length, standing AP radiographs of bilateral lower extremities (some radiographs were done at outside institutions and were not available for alignment measurements for this study). Contact administrator regarding this item (to report mistakes or request changes), e: Thein R, Bronak S, Thein R, Haviv B. Distal femoral osteotomy for valgus arthritic knees. The distal femoral cortex was removed to expose 80 mm of the distal portion of the revision femoral stem. 5. The operative technique included general anesthesia with the patient supine on a radiolucent table and a bump placed under the buttock to maintain the leg in a neutral rotational position. *StimuBlast is a registered trademark of AlloSource. For younger patients with ligament and cartilage surgeries the success rate is much high as 90% at 10 years and these procedures in young patients can last upwards of 20 years. Distal Femoral Osteotomy vlog: Hardware removal - YouTube Last vlog!My blog: https://orbite-beast.tumblr.com/ Last vlog!My blog: https://orbite-beast.tumblr.com/. 11. White dotted line: mechanical axes of the femur. Background: Our reoperation and survivorship rates for patients with arthritis are similar to these other studies discussed previously. PROMs and complications were analyzed using random-effects modeling to identify differences in outcomes as a function of surgical technique. As part of the planning for a distal femoral osteotomy, we like to put most of our patients into a lateral compartment unloader brace. Survivorship at 5 years, with conversion to arthroplasty as the endpoint, was 74% in the arthritis group and 92% in the joint preservation group. When the amount of planned correction was obtained at the osteotomy site, lateral fluoroscopic images were obtained to ensure there was no flexion or extension of the osteotomy. Distal femoral varus osteotomy for osteoarthritis of the knee. The average patient age at surgery is 33 11 years with mean BMI of 28 6. The opening-wedge plate was then placed and fixed with four screws (Fig. Epub 2019 Nov 27. By continuing to use this website you are giving consent to cookies being used. Distal femoral varus osteotomy in the valgus osteoarthritic knee. In situations where the lateral cortex or anteromedial cortex has been inadvertently fractured, the Two-Hole Osteotomy Support Plate Implant System can be utilized to help fixate these fractures. For patients with ACL deficiencies, if they have significant arthritis in their lateral compartment with valgus alignment, then a concurrent ACL reconstruction with a distal femoral osteotomy may be indicated. 1). Epub 2018 Oct 5. Disclaimer, National Library of Medicine (including injections and arthroscopic surgery), I heard Dr. La Prade was going to practice in the Twin Cities - where I live, & waited for him, based on his renown reputation. Postoperatively, seven of 15 knees in the arthritis group and three of six knees in the joint preservation group were within the correction goal of 3 from neutral mechanical alignment. In this study we report on a cohort of patients who underwent this procedure either for symptomatic lateral compartment knee arthritis or in patients undergoing a joint preservation procedure. Orthopedic Surgeon & Sports Medicine Specialist Two knees (two patients) underwent a medial closing-wedge osteotomy and were not included in the present study. a A valgus knee with the mechanical axis., MeSH Knee Society knee scores improved from 43 to 78. Thin and low profile to prevent overlying soft-tissue irritation, the titanium plate is attached to bone using 4.5 mm and 6.5 mm cancellous screws that seat flush to the plate surface. A survivorship analysis. Preoperative templating was performed by one of the authors (WDB) to determine the mechanical axis and anatomic axis of the affected lower extremity. 2021. Jacobi M, Wahl P, Bouaicha S, Jakob RP, Gautier E. Distal femoral varus osteotomy: problems associated with the lateral open-wedge technique. Disclaimer, National Library of Medicine Return to Sport and Work Following Distal Femoral Varus Osteotomy: A Systematic Review. Primary total hip arthroplasty can become a challenge for the experienced surgeon in the setting of a deformed proximal femur or with re In the arthritis group, the mean IKDC pain score improved from 6 (SD, 2) to 3 (SD, 3), the mean IKDC function score improved from 4 (SD, 1) to 7 (SD, 2), and the mean total IKDC score improved from 47 (SD, 15) to 67 (SD, 10).

Unable to load your collection due to an error, Unable to load your delegates due to an error. Bookshelf Clin Sports Med. Specifically designretractors are then used to clear any soft tissue and the osteotomy isprecisely performed preserving approximately 1 cm of the medial cortex. Osteosynthesis with a malleable implant. Lower extremity malalignment in association with arthritis or cartilage deficiency is a clinical challenge. (3) What are the nonunion, complication, and reoperation rates after lateral opening-wedge osteotomy? These are the lateral opening wedge osteotomy, whereby a bone wedge is placed into the outside portion of the femur to change the alignment or a closing wedge medial distal femoral osteotomy, whereby a bone wedge is taken out and the bone is collapsed down to change the alignment. Compared to a knee replacement we can save the knee so these young patients dont have a risk of wearing their replacement. your express consent. My right knee was totally destroyed; ACL, MCL, PCL all severely torn; the patella was the only thing intact in my right knee. Survivorship at 10, 15, and 20 years was 90%, 79%, and 21.5%, respectively. Also, partial knee replacements of the outside of the knee do not last as long versus inside partial replacement so there is even more reason to consider distal femoral osteotomy compared to knee replacement. Supracondylar osteotomy of the femur with use of compression. Orthopedic Surgeon & Sports Medicine Specialist I could not bear weight on my right side though I tried repeatedly, but finally I went and got an MRI and one of the orthopedic surgeons that I worked with was shocked when he saw the MRI result. In general, we keep patients non-weightbearing for 8 weeks for the distal femoral osteotomy, obtain x-rays at 8 weeks to ensure there is sufficient healing, and then initiate a partial protective weightbearing program, advancing it one-quarter body weight per week until the 3-month point. I was life flighted to MCR in Loveland, CO. My orthopedic injuries were severe, but totally missesd by the orthopedic team at Poudre. Removal of hardware was performed in 63% after 1.3 years (0.6-2.1 years). This video shows the surgical technique for a medial opening wedge distal femoral osteotomy, for correcting a knee with valgus deformity (courtesy of Arthrex). Two studies [1, 10] on the medial closing-wedge technique report a mean improvement in the tibiofemoral angle of 11 and 16, respectively. (3) What are the nonunion, complication, and reoperation rates after lateral opening-wedge osteotomy? The authors concluded that osteotomy was indicated in younger (mean, 46 years) high-activity patients, but after 20 years most patients were converted to TKA. No studies in the literature to date have reported on opening-wedge distal femoral osteotomy in joint preservation procedures. Routine closure was then performed and the patient was placed into a ROM brace. The indications for osteotomy included symptomatic lateral compartment arthritis with clinical valgus deformity or a cartilage or meniscal defect in the lateral compartment with clinical valgus alignment. OSferion wedges are intended to be used in conjunction with the distal femoral and high tibial opening wedge osteotomy plates and screws to promote healing and provide added rigidity to the repair. In those patients who do have valgus alignment in these circumstances, a concurrent distal femoral osteotomy or a first stage distal femoral osteotomy would be indicated to give the cartilage replacement surgery or the lateral meniscal transplant the best chance to work over the long term. While rates of required hardware removal secondary to these complications were as high as 72% in 1 group, 7 all remaining articles reported lower rates of hardware removal. Grant H. Garcia, MD 2022 Dec 6;23(23):15365. doi: 10.3390/ijms232315365. Each author certifies that he or she, or a member of his or her immediate family, has no funding or commercial associations (eg, consultancies, stock ownership, equity interest, patent/licensing arrangements, etc) that might pose a conflict of interest in connection with the submitted article. Further research with larger groups in this area is needed. (1) Does lateral opening-wedge osteotomy lead to accurate correction? government site. Future studies with more patients and longer followup will provide clarity on this topic. Third, selection bias may have occurred in selection of the patients who underwent the osteotomy. Edina, MN 55435, EAGAN-VIKING LAKES OFFICE There was one nonunion. doi:10.1177/2325967114S00051. Improvements in the IKDC scores were noted postoperatively. All ICMJE Conflict of Interest Forms for authors and Clinical Orthopaedics and Related Research editors and board members are on file with the publication and can be viewed on request. In general, most U.S. surgeons perform an opening wedge distal femoral osteotomy to realign the knee. EFORT Open Rev. White continuous lines: femur and tibia joint line. Lateral opening-wedge distal femoral osteotomy was less accurate in correction of valgus deformity than we expected, but the procedure was associated with improved pain and function and a 5-year survivorship of 74% and 92% in the arthritis and joint preservation patient cohorts, respectively. The purpose of our study was to report on a series of opening-wedge distal femoral varus osteotomies used to treat osteoarthritis of the lateral compartment or as an adjunct to correct malalignment with cartilage or meniscal restoration. Additionally, each screw can be pivoted within the plate's mobile bushing system to optimize placement prior to being locked to the plate, creating a rigid construct. 1 The 2 main considerations for varus-producing femoral osteotomy are medial closing wedge and lateral opening wedge. Clin Orthop Relat Res. Distal femoral osteotomy (DFO) is a well-accepted procedure for the treatment of femoral deformities and associated symptoms including osteoarthritis, especially in younger and physically active patients in whom knee arthroplasty is undesirable. Of the 31 knees, 20 (14 in the arthritis group and six in the joint preservation group) had preoperative mechanical axis measurements and 21 (15 in the arthritis group and six in the joint preservation group) had postoperative mechanical axis measurements. A sterile tourniquet was used. Specifically, we sought to determine the following: (1) Does lateral opening-wedge osteotomy lead to accurate correction?

Oftentimes, we will place the patient into a lateral compartment unloader brace to use as a screen to determine that a distal femoral osteotomy may be a useful procedure. The frequency of hardware removal was higher than we expected and indicates that this should be discussed with patients preoperatively. The indications for osteotomy included symptomatic lateral compartment arthritis with valgus deformity or an isolated cartilage defect in the lateral compartment with valgus or minimal varus alignment.
