Optimizing indications and technique in osteotomies around the knee. Once the osteotomy was mobile, an opening-wedge device was placed. Distal femoral varus osteotomy for osteoarthritis of the knee. This site needs JavaScript to work properly. The remaining 31 knees (82%) in 30 patients comprised the study population. (3) What are the nonunion, complication, and reoperation rates after lateral opening-wedge osteotomy? 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. Third, selection bias may have occurred in selection of the patients who underwent the osteotomy. View Doctor Profile. 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. Two studies [3, 4] on the lateral opening-wedge technique report a mean improvement in the tibiofemoral angle of 11 and 6, respectively. 10. Duivenvoorden T, Brouwer RW, Baan A, Bos PK, Reijman M, Bierma-Zeinstra SM, Verhaar JA. This was devastating news after being a top triathlete (3rd in the world in my age group in 1989 & 1st nationally in my age group) and a big marathon runner. Dr. Garcia will take limb alignment films to identify have much correction is needed. 1 Even with evolving fixation strategies and implants, . Other than concurrently either adding bone or taking out bone, there may not be a big difference between either technique. 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. Thirty-eight knees (97%) in 36 patients were lateral opening-wedge varus-producing osteotomies; of those, 31 knees (82%) in 30 patients had followup at a minimum of 2 years (mean, 5 years; SD, 2; range, 2-12 years) and comprised the study population. Some features of this site may not work without it. Comparison of closing-wedge and opening-wedge high tibial osteotomy for medial compartment osteoarthritis of the knee: a randomized controlled trial with a six-year follow-up. 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. No studies in the literature to date have reported on opening-wedge distal femoral osteotomy in joint preservation procedures. The osteotomy is supported by one in a series of Femoral Osteotomy Plates and secured with traditional proximal bicortical screw and distal cancellous screw fixation. Survivorship of the osteotomy, with conversion to arthroplasty (UKA or TKA) as the endpoint, was calculated using the Kaplan-Meier method. After proper soft tissue exposure and identification of the fracture it is recommended to close the prepared osteotomy before application of the plate. *StimuBlast is a registered trademark of AlloSource. Based on these studies, a wide variation exists in the amount of correction as well as the final alignment correction achieved. The frequency of hardware removal was higher than we expected and indicates that this should be discussed with patients preoperatively. HSS J. 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. Wang JW, Hsu CC. The survival rate for CW DFO was 81.5% (mean follow-up, 8.8 4.3 years) compared with 90.5% for OW DFO (mean follow-up, 4.5 1.5 years). The third most common reason for a distal femoral osteotomy is in patients who have a chronic MCL tear who are in valgus alignment. 1. 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. Statistical analyses for survivorship were performed using MedCalc for Windows, version 12.5 (MedCalc Software, Ostend, Belgium). Most studies for osteotomies around the knee report on the use of proximal tibial valgus osteotomy for varus deformities [5, 8]. Seven knees in six patients were lost to followup before 2 years and were excluded. 2022 Dec 19;23(1):1105. doi: 10.1186/s12891-022-06078-y. These patients were either treated nonoperatively or were considered for TKA. This transfer bias is important to remember when reviewing our results. Return to Sport and Work Following Distal Femoral Varus Osteotomy: A Systematic Review. SPSS Version 13.0 (IBM Corporation, Armonk, NY, USA) was used for all statistical analyses. 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. Specifically designretractors are then used to clear any soft tissue and the osteotomy isprecisely performed preserving approximately 1 cm of the medial cortex. I have looked many times for answers on my tibial tubercle osteotomy and never found any as detailed as i needed. 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. EDINA- CROSSTOWN OFFICE 16. Orthop J Sports Med. Dewilde et al. An official website of the United States government. Sternheim A, Garbedian S, Backstein D. Distal femoral varus osteotomy: unloading the lateral compartment: long-term follow-up of 45 medial closing wedge osteotomies. Saithna et al. Survivorship at 7 years with revision surgery or conversion to TKA as the endpoint was 82%. 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. Hey - if he is good enough for Olympic and professional athletes..he's good enough for me! Distal Femoral Medial Opening Wedge Osteotomy for Post-Traumatic, Distal Femoral Varus Deformity. 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. HHS Vulnerability Disclosure, Help a A valgus knee with the mechanical axis., MeSH Abdel Khalik H, Lameire DL, Rubinger L, Ekhtiari S, Khanna V, Ayeni OR. A distal femoral involves a surgical cut of the bone at bottom of the femur. 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. Orthop Traumatol Surg Res. In general, patients who smoke are not candidates for a distal femoral osteotomy because bone does not heal very well in smokers and this would generally be a contraindicated surgical procedure in this circumstance. Wylie JD, Jones DL, Hartley MK, Kapron AL, Krych AJ, Aoki SK, Maak TG. 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%]). [4] reported that four of 19 patients who had an opening-wedge osteotomy underwent hardware removal, one patient underwent fracture fixation, and two patients were converted to TKA. Our clinical and radiographic results are comparable to published series evaluating medial closing-wedge distal femoral osteotomy. 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. Clipboard, Search History, and several other advanced features are temporarily unavailable. 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 Many of the patients who had postoperative films were not within 3 of neutral alignment. Before This AP radiograph demonstrates a healed nonunion (left). official website and that any information you provide is encrypted Distal Femoral Osteotomy. 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 meniscus allografting) has been performed. Calculations of the specific amount of opening that is needed using the current digital x-ray systems are very accurate. Federal government websites often end in .gov or .mil. The authors reported a survivorship of 64% at 10 years, which included seven failures (three early and four late). Delva ML, Samuel LT, Roth A, Yalin S, Kamath AF. Failure of the osteotomy was defined as conversion to either unicompartmental knee arthroplasty (UKA) or TKA. 2019. Systematic review, Level of evidence, 4. After successful application of the plate and screws re-open the osteotomy allowing compression at the fracture site. . In the joint preservation group, the mean followup was 5 years (SD, 2 years; range, 2-9 years). The https:// ensures that you are connecting to the Introduction. The unloading osteotomy is especially useful in the young, active patient as an adjunct procedure for cartilage repair. Specifically designretractors are then used to clear any soft tissue and the osteotomy isprecisely performed preserving approximately 1 cm of the medial cortex. OSferions micro- and macroporous structure allows it to be resorbed and replaced by bone during the healing process. Usually bone graft, plates, and screws are used to hold open the distal femoral osteotomy. No postoperative infections, nerve palsies, or wound complications occurred. If patients have knock kneed knees and arthritis this can be a very effective surgery and delay the need for a knee replacement. 2019 Jul;38(3):351-359. doi: 10.1016/j.csm.2019.02.004. (1) Does lateral opening-wedge osteotomy lead to accurate correction? As part of the planning for a distal femoral osteotomy, we like to put most of our patients into a lateral compartment unloader brace. Finkelstein JA, Gross AE, Davis A. Varus osteotomy of the distal part of the femur. 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. This was an unexpected but noteworthy finding. For larger procedures in younger patient full recovery may take longer based on the other procedures performed. osc@harvard.edu, t: For the meniscus and cartilage transplant patients realigning the knee can increase the healing of the transplant and improve survival. 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. The reoperation rate and survivorship were 53% and 74%, respectively, for the arthritis group and 50% and 92%, respectively, for the joint preservation group. Epub 2020 Jul 20. Clin Orthop Relat Res. Future studies with more patients and longer followup will provide clarity on this topic. Total knee arthroplasty after opening-versus closing-wedge high tibial osteotomy. See this image and copyright information in PMC. Joint line convergence angle (JLCA) = 5, mechanical lateral distal femoral angle (mLDFA) = 84. b Preoperative planning of opening-wedge (DFO). At latest followup, Hospital for Special Surgery knee scores improved from 65 to 84. Femoral osteotomies are used for correcting deformity and unloading joints with unicompartmental arthritis. 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. In general, these are performed for patients with knock knees, which we call valgus alignment, and the goal of the surgery is to realign them such that the weightbearing axis is changed to pass either through the center of the knee or just barely into the inside compartment of the knee. 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. Some distal femoral osteotomies involve taking out bone where you let the . [4] reported on the outcome of opening-wedge distal femoral osteotomy for lateral arthritis of the knee in 19 patients using the Puddu plate and calcium phosphate. Ten knees in the arthritis group and six knees in the joint preservation group had additional surgery after the osteotomy, consisting primarily of hardware removal, arthroscopy for cartilage-related conditions, or conversion to arthroplasty. Clinical Orthopaedics and Related Research neither advocates nor endorses the use of any treatment, drug, or device. Wang and Hsu [20] reported on 30 knees undergoing varus osteotomy with a medial blade plate. Usually bone graft, plates, and screws are used to hold open the distal femoral osteotomy. Hardware prominence and removal rates have been shown to be approximately 2.5 times greater in the LOW group . Feucht MJ, Winkler PW, Mehl J, Bode G, Forkel P, Imhoff AB, Lutz PM. This work was performed at Scripps Clinic, La Jolla, CA, USA. 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 Would you like email updates of new search results? Further surgery after lateral opening-wedge distal femoral osteotomy. In general, one should be between the ages of 16 (with closed growth plates) and a roughly upper age of 55 to benefit from a distal femoral osteotomy. 2017 Nov;103(7):1035-1039. doi: 10.1016/j.otsr.2017.07.011. 2016 Oct;32(10):2141-2147. doi: 10.1016/j.arthro.2016.04.010. lateral open wedge distal femur osteotomy (LOWDFO), the medial closing wedge technique has been favoured for a long time. Twenty-one of 31 knees had postoperative radiographic data available for review. In total, we included 23 retrospective studies (n = 619 knees), of which 10 studies (n = 271 knees) reported outcomes after CW DFO and 13 studies (n = 348 knees) reported on OW DFO outcomes. Opening wedge distal femoral varus osteotomy using the Puddu plate and calcium phosphate bone cement. Second, three different fixation devices were used in the series to secure the osteotomy site and insufficient numbers of patients with each device did not allow analysis of a difference in outcome. Full weightbearing was allowed at radiographic evidence of healing, typically between 8 and 16 weeks (Fig. FOIA The use of varus-producing osteotomies for valgus knee deformity is less common and limited clinical studies have been published [1, 2, 6, 7, 10, 12, 13, 15, 16, 20]. There are often many symposia and debates at national and international meetings on this topic. This image shows radiographic appearance of a healed opening-wedge distal femoral osteotomy. The authors reported 18 of 19 patients were satisfied. Results: Of the 71 patients who followed -up beyond six months post-operatively, seven eventually converted to total knee arthroplasty (9.9%). This is what this term means. official website and that any information you provide is encrypted 12. I was life flighted to MCR in Loveland, CO. My orthopedic injuries were severe, but totally missesd by the orthopedic team at Poudre. Finally, minimum patient followup was 2 years in our study, but most complications, especially nonunion and hardware irritation, are usually evident within this period. 4. The patients who underwent a TKA were female (age, 26 and 40.1 years; BMI, 30.5 and 30.7, respectively) and received these procedures 2.4 and 3.2 years after their DFVO because . Knee Surg Sports Traumatol Arthrosc. This site needs JavaScript to work properly. In the arthritis group, the mean IKDC total score improved from 47 (SD, 15) preoperatively to 67 (SD, 10) postoperatively. Survivorship at 5 years, with conversion to arthroplasty as the endpoint, was 74% in the arthritis group and 92% in the joint preservation group. Distal femoral osteotomy for valgus deformity of the knee. 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 situations involving lateral unicompartmental arthritis unresponsive to conservative treatment options, the Distal Femoral Opening Wedge Osteotomy System is a safer, more reproducible alternative to traditional closing wedge distal femoral osteotomies. In our hands, almost all patients who benefit from the use of a lateral unloader brace do very well with a later performed distal femoral osteotomy and are able to correct the knock knee condition. View Profile, Grant H. Garcia, MD These studies have small numbers of patients and variable lengths of followup. for hardware removal following operative xation of distal radius fractures. Epub 2016 Jun 3. SPECIMENS: Multiple cultures from the right ankle. Achieving our desired correction of 3 from neutral alignment was clinically difficult. Relative disadvantages include potential for delayed union or nonunion and irritation of the sensitive lateral knee structures by hardware or surgical trauma. Epub 2019 Mar 26. 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]. 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. Some distal femoral osteotomies involve taking out bone where you let the leg compress on itself, this is called a closing wedge distal femoral osteotomy. Time to radiographic union, complications, and reoperations were captured. This surgery aims to reduce lateral compartment overload and to prevent knee osteoarthritis (OA) progression [ 1 ]. Otherwise, there is a risk that the hinge on the inside part of the knee could crack or the screws could break because too much weight is being placed on them from relying on the plate and screws to hold the fracture apart rather than allowing the bone to heal. Survivorship and Complications of the Distal Femoral Osteotomy. Orthopaedic Journal of Sports Medicine 2 (2 Suppl): 2325967114S00051. 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%. Keywords: 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). Book an appointment today! J Knee Surg. Long-term survival data, defined as conversion to total knee arthroplasty, were analyzed using a multiple metaregression model as a function of individual study follow-up time points and surgical technique. The success rate of distal femoral osteotomies is felt to be about 70% to 75% at 10 years. Our retrospective study aims to evaluate the outcomes and analyze survivorship of the distal femoral osteotomy until eventual conversion to knee arthroplasty. 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. Kosashvili Y, Safir O, Gross A, Morag G, Lakstein D, Backstein D. Distal femoral varus osteotomy for lateral osteoarthritis of the knee: a minimum ten-year follow-up. 6. Generally, these patients are younger than 55 years old. 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 meniscus allografting) has been performed. Means and frequencies were calculated to describe patient characteristics of the study population, type of fixation and graft material, amount of intraoperative correction, and mechanical axis alignment. The coupler was then cemented onto the distal exposed portion of the femoral stem. At an average 99-month followup, 83% were reported as satisfactory and three were converted to TKA. Contemporary Knee Osteotomy in the United States: High Tibial Osteotomy and Distal Femoral Osteotomy Have Comparable Complication Rates despite Differing Demographic Profiles. Multiple metaregression demonstrated that patient follow-up (P < .001) was significantly associated with knee survival, while surgical technique (P = .810) was not a predictor of clinical failure. 4010 W. 65th St. Improvement in pain and function of this procedure at intermediate-term followup has been acceptable [1, 2, 6, 7, 12, 13, 20]. Cameron, James I. MD1; McCauley, Julie C. MPHc2; Kermanshahi, Arash Y. MD3; Bugbee, William D.

Ehlinger M, D'Ambrosio A, Vie P, Leclerc S, Bonnomet F, Bonnevialle P, Lustig S, Parratte S, Colmar M, Argenson JN; French Society of Orthopedic Surgery, Traumatology (SoFCOT). However, osteoarthritis continues to progress and multiple arthroscopic or open procedures may be required despite a successful osteotomy. Federal government websites often end in .gov or .mil. Importantly, our survivorship in the joint preservation group was higher than any other reported in the literature to date. Ramanathan, Deepak, Arvind Von Keudell, Tom Minas, and Andreas H. Gomoll. They also reported two cases of loss of correction, one infection, and one nonunion. Unable to load your collection due to an error, Unable to load your delegates due to an error. When performed at the optimal time in a carefully selected patient, distal femoral osteotomy can provide adequate joint function for many years until arthroplasty becomes inevitable. In general, the plates and screws that are used to fix long bone fractures are left in for a minimum of one year prior to having them taken out. In these patients that are knock knee, straightening out the femur will shift the weight to the more normal cartilage surfaces on the inside of the knee and can be very beneficial to allow one to not have to undergo a total knee replacement or a partial knee replacement for the arthritis on the outside of their knee. Stahelin T, Hardegger F, Ward JC. sharing sensitive information, make sure youre on a federal Careful selection of each surgical candidate is necessary to ensure maximum benefit. Objectives: 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. (3) What are the nonunion, complication, and reoperation rates after lateral opening-wedge osteotomy? This surgery is very successful in these cases and can dramatically improve success of these procedures if done in conjunction. 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. 2.
