Kaplan - Meier survivorship analysis estimates mean survival time of 123 8 months (with 95% confidence interval of 107 - 138) and survival probability at 10 years follow-up is estimated at 78%. Osteotomies around the knee are well-recognized treatments for unloading the affected compartment in cases of lower limb malalignment. 2022 Dec 6;23(23):15365. doi: 10.3390/ijms232315365. The two groups of patients (arthritis group and joint preservation group) were considered separately when analyzing the data. Isolated high tibial osteotomy is appropriate in less than two-thirds of varus knees if excessive overcorrection of the medial proximal tibial angle should be avoided. Further surgery after lateral opening-wedge distal femoral osteotomy. (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. official website and that any information you provide is encrypted Each author certifies that his or her institution approved the human protocol for this investigation, that all investigations were conducted in conformity with ethical principles of research, and that informed consent for participation in the study was obtained. Epub 2022 Jun 8. My right knee was totally destroyed; ACL, MCL, PCL all severely torn; the patella was the only thing intact in my right knee. Generally, a hinge of 8-15 mm is made to improve the alignment and offset potential issues of the knee. Technique selection should be based on shared patient-physician decision making with an emphasis on surgeon preference and technique familiarity. Careers. The theoretical advantages of the opening-wedge technique over the medial closing-wedge technique include a single bone cut, avoidance of vascular structures, better control of the amount of correction, and more anatomic correction of the typical pathoanatomy of excessive distal femoral valgus [9]. Results: Of the 71 patients who followed -up beyond six months post-operatively, seven eventually converted to total knee arthroplasty (9.9%). The reoperation rate and survivorship were 53% and 74%, respectively, for the arthritis group and 50% and 92%, respectively, for the joint preservation group. 2022 May;18(2):297-306. doi: 10.1177/15563316211051295. 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. DFO to correct genu valgum has traditionally been completed through a medial closing wedge distal femoral osteotomy (MCWDFO). 1. Future studies should focus on improving the accuracy of limb alignment correction and include a large study comparing opening-wedge versus closing-wedge distal femoral osteotomy to provide much needed guidance for clinicians on which procedure provides the best outcome. Apply the anatomically contoured two hole plate over the fracture site and secure it with two 4 mm x 30 mm titanium self-tapping cancellous screws. Patients with a cartilage defect in the lateral compartment who also had medial knee pain were also not deemed candidates for the osteotomy. Medial closing-wedge osteotomy A medial-side distal femoral approach is normally used with a skin incision starting 2 cm distal to the medial epicondyle and extending 15 cm proximally. 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. a Preoperative long-leg standing X-rays. Return to Sport and Work Following Distal Femoral Varus Osteotomy: A Systematic Review. There are usually 3 main indications for distal femoral osteotomies. Epub 2014 Dec 24. Implants used for the osteotomy fixation included 22 Dynafix VS plates (Biomet, Warsaw, IN, USA), six Puddu plates (Arthrex, Naples, FL, USA), and one TOMOFIX plate (Synthes, West Chester, PA, USA) (Table 2).

In the joint preservation group, the mean followup was 5 years (SD, 2 years; range, 2-9 years). After proper soft tissue exposure and identification of the fracture it is recommended to close the prepared osteotomy before application of the plate. Although similar . 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. The system is designed to correct valgus malalignment through the knee joint and is carried out through a distal lateral femoral approach. An 8- to 10-cm incision was made on the lateral distal femur from the lateral epicondyle proximally. pt13: proximal femoral plate removal pt14: chiari pelvic osteotomy (child with neurological impairment) pt15: san diego / degas pelvic osteotomy (child with neurological impairment) pt16: distal femoral rotational osteotomy pt17: distal tibial rotational osteotomy pt18: evan's calcaneal lengthening pt19: triple arthrodesis pt20: botox . This realignment moves the force on the arthritis part of the knee to the normal part. HHS Vulnerability Disclosure, Help This study is to analyze the indications of the two most popular techniques of distal femoral osteotomy (DFO) performed in patients with valgus malalignment and symptomatic degenerative changes in the lateral compartment of the knee and to evaluate the clinical and radiological outcome of a case series of patients who have received this operation at the Department of Orthopaedics and . In the arthritis group, the mean IKDC total score improved from 47 (SD, 15) preoperatively to 67 (SD, 10) postoperatively. Additionally, each screw can be . No postoperative infections, nerve palsies, or wound complications occurred. 2022 Jun 8;7(6):396-403. doi: 10.1530/EOR-22-0057. I can run, bike, & climb mountains. Delva ML, Samuel LT, Roth A, Yalin S, Kamath AF. (3) What are the nonunion, complication, and reoperation rates after lateral opening-wedge osteotomy? Find top doctors who perform Knee Osteotomy near you in Vallejo, CA. The small number of patients included in this study makes it difficult to draw conclusions on the data we present. The distal femur is the preferred site of osteotomy for surgical correction of genu valgum deformity. The most common type of distal femoral osteotomy is one that involves an incision on the outside of the knee. Federal government websites often end in .gov or .mil. 3. See this image and copyright information in PMC. Future studies with more patients and longer followup will provide clarity on this topic. Keywords: Patients in both groups demonstrated improvements in the IKDC pain and function scores from preoperatively to postoperatively. 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. 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. I was life flighted to MCR in Loveland, CO. My orthopedic injuries were severe, but totally missesd by the orthopedic team at Poudre. JavaScript is disabled for your browser. 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. Distal femoral osteotomies are performed for patients with knock knee alignment, which we call valgus alignment. A literature review was performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines utilizing PubMed, Cochrane Database, Ovid/MEDLINE, and Scopus. Download Citation | Biomechanical study of the stiffness of the femoral locking compression plate of an external fixator for lower tibial fractures | Background: A locking compression plate (LCP . Careers. For the meniscus and cartilage transplant patients realigning the knee can increase the healing of the transplant and improve survival. Jacobi M, Wahl P, Bouaicha S, Jakob RP, Gautier E. Distal femoral varus osteotomy: problems associated with the lateral open-wedge technique. For more information, please refer to our Privacy Policy. Additionally, each screw can be pivoted within the plate's mobile bushing system to . Importantly, our survivorship in the joint preservation group was higher than any other reported in the literature to date. The fascia over the vastus medialis is incised and retracted laterally and anteriorly to expose the femoral shaft. 12. After surgery patients are non-weight bearing for 6 weeks. For cartilage patients the cut off is slightly lower at 3-4 degrees of valgus. Healy WL, Anglen JO, Wasilewski SA, Krackow KA. Further research with larger groups in this area is needed. An official website of the United States government. Wang and Hsu [20] reported on 30 knees undergoing varus osteotomy with a medial blade plate. Generally, a hinge of 8-15 mm is made to improve the alignment and offset potential issues of the knee. Methods: The authors reported 18 of 19 patients were satisfied.

Garcia, MD Wolters Kluwer Health Ten of 19 knees in the arthritis group and six of 12 knees in the joint preservation group had further surgery (Table 4). 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. Two studies [3, 4] on the lateral opening-wedge technique report a mean improvement in the tibiofemoral angle of 11 and 6, respectively. 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. The ContourLock distal femoral osteotomy plates are designed to work in conjunction with the Osteotomy Instrument System. The IKDC score improved from 36 to 53 (p < 0.05). 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. Between 2000 and 2010, we performed 40 distal femoral osteotomies. Relative disadvantages include potential for delayed union or nonunion and irritation of the sensitive lateral knee structures by hardware or surgical trauma. (1) Does lateral opening-wedge osteotomy lead to accurate correction? (2) What pain and function levels do patients experience after lateral opening-wedge osteotomy? Other associated procedures included lateral release, tibial tubercle osteotomy, quadricepsplasty and ACL reconstruction. Varus-producing distal femoral osteotomy has been described as a treatment option for symptomatic lateral compartment osteoarthritis in active individuals with genu valgum. (2) What pain and function levels do patients experience after lateral opening-wedge osteotomy? Once this is indicated, Dr. Garcia will discuss when this portion of the surgery will occur, or if a separate surgery is needed. Pilone C, Rosso F, Cottino U, Rossi R, Bonasia DE. 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. Predictable healing of the osteotomy was observed. lateral, distal femoral osteotomy. Distal femoral osteotomy (DFO) is a useful procedure in the young patient with symptomatic unicompartmental osteoarthritis and valgus malalignment to avoid or postpone knee arthroplasty. Orthopedic Surgeon & Sports Medicine Specialist 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). This surgery is very successful in these cases and can dramatically improve success of these procedures if done in conjunction. Eur J Radiol Open. Epub 2020 Jul 20. Seven knees in six patients were lost to followup before 2 years and were excluded. 8600 Rockville Pike 2019 Jul;38(3):351-359. doi: 10.1016/j.csm.2019.02.004. 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. Epub 2016 Dec 21. Survivorship at 10, 15, and 20 years was 90%, 79%, and 21.5%, respectively.

Thedesired amount of angular correction is achieved utilizing the Osteotome Jackor Osteotomy Wedge and the osteotomy site is packed with allograft or autograftbone void filler. A five-to-11-year follow-up study. At an average 99-month followup, 83% were reported as satisfactory and three were converted to TKA. Other less common complications included hardware failure (3.8%), septic arthritis (3.8%) and nonunion (2.6%). Duivenvoorden T, Brouwer RW, Baan A, Bos PK, Reijman M, Bierma-Zeinstra SM, Verhaar JA. Unable to load your collection due to an error, Unable to load your delegates due to an error. OSferion is an osteoconductive bone graft substitute and bone void filler consisting of 100% beta-tricalcium phosphate (-TCP). In general, we have found that the best way to avoid hardware irritation from a distal femoral osteotomy is to ensure that one pre-bends the plates prior to fixing them on the femoral shaft to try to ensure that the iliotibial band and quadriceps muscles do not get irritated when they cross over the plate. However, with renewed interest in biologic restoration and the use of cartilage restoration techniques, osteotomies have seen an increase in popularity, particularly in younger (age 25-40 years) patients. The https:// ensures that you are connecting to the Given . After successful application of the plate and screws re-open the osteotomy allowing compression at the fracture site. Other than concurrently either adding bone or taking out bone, there may not be a big difference between either technique. 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. It is felt that if the valgus alignment is not corrected with a reconstruction of a chronic MCL tear, that there is a much higher risk the MCL tear will stretch out. 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. The use of an opening-wedge osteotomy on the tibial side for varus deformity has become well established as the favored alternative to the previously more common closing-wedge techniques [8]. Unfortunately, pre-bending the plate may not always be successful at eliminating future hardware irritation in smaller patients, so these patients may have to wait until the osteotomy is completely healed and a minimum of one year after surgery prior to having the plate and screws that are causing any of the hardware irritation removed. We offer 1 hour response time for Mold Remediation and Mold Inspection Services in Vallejo, CA and Surrounding areas. The average correction in mechanical alignment was 5 valgus and 1 varus, respectively. This was an unexpected but noteworthy finding.

Saithna A, Kundra R, Getgood A, Spalding T. Opening wedge distal femoral varus osteotomy for lateral compartment osteoarthritis in the valgus knee. 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. Background:Distal femoral varus osteotomy (DFVO) is a well-described procedure to address valgus deformity of the knee. No significant differences were appreciated in the incidence of complications reported in patients undergoing CW (20%) versus OW (33%) DFO (P = .432). SPECIMENS: Multiple cultures from the right ankle. White continuous lines: femur and tibia joint line. Orthop Traumatol Surg Res. 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%]). Please try again soon. Emed Res 2: 100013. . In the arthritis group, the average preoperative mechanical axis was 7 valgus (SD, 4; range, 17 valgus to 1 varus). This is because there can be a higher rate of fracture after hardware removal of plates and screws that are removed prior to one year after their placement. Dewilde et al. Intraoperative fluoroscopic and visual analysis of correction to neutral mechanical axis is not as accurate as we had anticipated. Five-year survivorship was 74% in the arthritis group and 92% in the joint preservation group with conversion to arthroplasty as the endpoint. 11. They also reported two cases of loss of correction, one infection, and one nonunion. *StimuBlast is a registered trademark of AlloSource.

Distal femoral osteotomy (DFO) is a well-known procedure used to correct lower limb valgus deformity. Please try after some time. The distal femoral cortex was removed to expose 80 mm of the distal portion of the revision femoral stem. View Doctor Profile. Analysis of bone union after medial closing wedge distal femoral osteotomy using a new radiographic scoring system. Further studies on alignment correction are needed for clinicians to determine the optimum position of the mechanical axis and to decide whether opening-wedge or closing-wedge osteotomy provides optimal improvement in alignment. Concurrent with this, a plate and screws are placed on the outside of the knee and bone graft is placed into the opening wedge which is created to assist with healing of the gap. Phil Downer, M.D | Additional procedures at the time of lateral opening-wedge distal femoral osteotomy. Clin Sports Med. 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. 1 Even with evolving fixation strategies and implants, . Right Knee Surgery After Auto Bicycle Accident, Medical Second Opinion Service MRI/X-ray Review, Lateral Patellotibial Ligament Reconstruction. Would you like email updates of new search results? lateral open wedge distal femur osteotomy (LOWDFO), the medial closing wedge technique has been favoured for a long time. Dewilde et al. We used the method of Paley [14] to determine the mechanical axis deviation and amount of required correction. Supracondylar osteotomy of the femur with use of compression. OSferions micro- and macroporous structure allows it to be resorbed and replaced by bone during the healing process. Medial opening-wedge proximal tibial osteotomy for varus knee deformity is commonly performed but lateral opening-wedge distal femoral osteotomy for a valgus knee deformity is less common. Arthroscopy. 2015 Jun;473(6):2009-15. doi: 10.1007/s11999-014-4106-8. Data is temporarily unavailable. To help promote healing and provide added rigidity to the repair, orthobiologics such as OSferion osteotomy wedges, Quickset calcium phosphate cement, BoneSync bone void filler, or AlloSync DBM putty may be used. Background: OSferion is an osteoconductive bone graft substitute and bone void filler consisting of 100% beta-tricalcium phosphate (-TCP). The frequency of hardware removal was higher than we expected and indicates that this should be discussed with patients preoperatively. 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). Hardware prominence and removal rates have been shown to be approximately 2.5 times greater in the LOW group. 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. . Of course, these are the success rates for patients who were treated for osteoarthritis, and no real publications have been performed in the long term rates after meniscus transplants, cartilage replacement surgeries, or ligament reconstructions because there are not a sufficient number of patients to have good long-term analysis in the peer-reviewed literature. There is still debate as to what the correct indication is and which surgical techniques lead to the best outcomes in performing a DFO. Most studies for osteotomies around the knee report on the use of proximal tibial valgus osteotomy for varus deformities [5, 8]. A distal femoral osteotomy can be performed for osteoarthritis when one has had development of osteoarthritis on the outside part of their knee, their knee alignment has become knock knee and is in valgus, and whereby the cartilage and the meniscus on the inside of the knee is still in good condition to whereby shifting the weight towards the inside of the knee would benefit the patient. a A valgus knee with the mechanical axis., MeSH Some error has occurred while processing your request. Distal femoral varus osteotomy for painful genu valgum. The first one is in patients who may have developed arthritis either from a previous lateral meniscectomy or genetic causes and who are found to have fairly normal cartilage in the rest of their knee, but have arthritis on the outside of their knee. Grant H. Garcia, MD No studies in the literature to date have reported on opening-wedge distal femoral osteotomy in joint preservation procedures. 17. Geometry of the Valgus Knee: Contradicting the Dogma of a Femoral-Based Deformity. An improved method of preoperative templating and refinement of the intraoperative technique may improve this. Opening- and Closing-Wedge Distal Femoral Osteotomy: A Systematic Review of Outcomes for Isolated Lateral Compartment Osteoarthritis Show all authors. The success rate of distal femoral osteotomies is felt to be about 70% to 75% at 10 years. Results: 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. Correction of valgus knee deformity with a supracondylar V osteotomy. Das et al. 13. Distal femoral varus osteotomy for osteoarthritis of the knee. Osteoarthritis as an Umbrella Term for Different Subsets of Humans Undergoing Joint Degeneration: The Need to Address the Differences to Develop Effective Conservative Treatments and Prevention Strategies. A distal femoral involves a surgical cut of the bone at bottom of the femur. This AP radiograph demonstrates a healed nonunion (left). Abdel Khalik H, Lameire DL, Rubinger L, Ekhtiari S, Khanna V, Ayeni OR. Call Us Today (888) 260-0449 MeSH Previous attempts to make it better provided only temporary relief. High tibial osteotomy increases patellofemoral pressure if adverted proximal, while open-wedge HTO with distal biplanar osteotomy discharges the patellofemoral joint: different open-wedge high tibial osteotomies compared to an extra-articular unloading device. X-rays are taken at each visit to confirm healing and check alignment. Its combination with various cartilage repair procedures has been shown to further improve outcomes. 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. The median preoperative valgus angle was 6.1 valgus (range 2-15.5). Thedesired amount of angular correction is achieved utilizing the Osteotome Jackor Osteotomy Wedge and the osteotomy site is packed with allograft or autograftbone void filler. This website uses cookies. 2021. 19. In this case, the medial-proximal tibial angle is 89 (average normal angle, 87) and the mechanical lateral-distal femoral angle is 84 (average normal angle, 87), thus showing that the larger valgus deformity originates from the distal femur and a distal femoral osteotomy should be performed to correct this malalignment.
