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. and transmitted securely. Hardware prominence and removal rates have been shown to be approximately 2.5 times greater in the LOW group . osc@harvard.edu, t: No patients noted a leg-length inequality and no persistent symptoms from the iliac crest bone graft site were noted. Usually bone graft, plates, and screws are used to hold open the distal femoral osteotomy. OSferions micro- and macroporous structure allows it to be resorbed and replaced by bone during the healing process. Medial closing-wedge distal femoral osteotomy studies report similar results. [15] reported on 21 knees that underwent opening-wedge distal femoral osteotomy with followup from 1.6 to 9.2 years. 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. The system is designed to correct valgus malalignment through the knee joint and is carried out through a distal lateral femoral approach. Statistical analyses for survivorship were performed using MedCalc for Windows, version 12.5 (MedCalc Software, Ostend, Belgium). Two studies [3, 4] on the lateral opening-wedge technique report a mean improvement in the tibiofemoral angle of 11 and 6, respectively. This work was performed at Scripps Clinic, La Jolla, CA, USA. Epub 2017 Sep 6. Conclusion: Distal femoral osteotomy is an acceptable surgical option for the young patient with severe unicompartmental knee osteoarthritis and malalignment. Soft tissue stabilization of the hinge position in medial closed wedge distal femoral osteotomy: an anatomical study. This AP radiograph demonstrates a healed nonunion (left). 2017 Nov;103(7):1035-1039. doi: 10.1016/j.otsr.2017.07.011. 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). We used the method of Paley [14] to determine the mechanical axis deviation and amount of required correction. . Your message has been successfully sent to your colleague. 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%. 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. 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. Before Third, selection bias may have occurred in selection of the patients who underwent the osteotomy. 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 . Opening- and Closing-Wedge Distal Femoral Osteotomy: A Systematic Review of Outcomes for Isolated Lateral Compartment Osteoarthritis. EFORT Open Rev. 2021 Oct;29(10):3299-3309. doi: 10.1007/s00167-020-06166-3. Finkelstein et al. Epub 2021 Oct 27. While this is very uncommon, putting weight on it before Dr. Garcia instructs you, high BMI or smoking can increase this risk. Technique selection should be based on shared patient-physician decision making with an emphasis on surgeon preference and technique familiarity. Patients with a cartilage defect in the lateral compartment who also had medial knee pain were also not deemed candidates for the osteotomy. For information on cookies and how you can disable them visit our Privacy and Cookie Policy. Distal femoral osteotomy (DFO) unloads the lateral joint compartment and can be performed using closing wedge (CW) or opening wedge (OW) techniques. Study design: 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. 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. All cases of arthrofibrosis were noted to have had intra-articular surgical manipulation for associated procedures such as cartilage repair. Previous attempts to make it better provided only temporary relief. I was life flighted to MCR in Loveland, CO. My orthopedic injuries were severe, but totally missesd by the orthopedic team at Poudre. Das et al. 2 Here we will focus on lateral opening wedge osteotomy (), its stated advantages and disadvantages, surgical indications, preoperative planning, surgical technique, and . The rst is a true Table 1. By continuing to use this website you are giving consent to cookies being used. Distal femoral varus osteotomy. Relative disadvantages include potential for delayed union or nonunion and irritation of the sensitive lateral knee structures by hardware or surgical trauma. 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. Epub 2022 Jun 8. Survivorship at 7 years with revision surgery or conversion to TKA as the endpoint was 82%. Broken hardware and screws were removed. 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. Given . 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. 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. Valgus knee deformity increases the risk for lateral articular chondral damage, contributing to earlier onset and accelerated progression of osteoarthritis. Arthroscopy. 2022 Jun 8;7(6):396-403. doi: 10.1530/EOR-22-0057. A distal femoral osteotomy (knock knee surgery) is a procedure whereby a surgical fracture is created at the end of the femur and the shape of the bone is changed. Finkelstein JA, Gross AE, Davis A. Varus osteotomy of the distal part of the femur. Call Us Today (888) 260-0449 Correction of valgus knee deformity with a supracondylar V osteotomy. 17. Many of the patients who had postoperative films were not within 3 of neutral alignment. Joint line convergence angle (JLCA) = 5, mechanical lateral distal femoral angle (mLDFA) = 84. b Preoperative planning of opening-wedge (DFO). http://dx.doi.org/10.1177/2325967114S00051. Osteotomies around the knee are well-recognized treatments for unloading the affected compartment in cases of lower limb malalignment. 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. After proper soft tissue exposure and identification of the fracture it is recommended to close the prepared osteotomy before application of the plate. 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. In general, most U.S. surgeons perform an opening wedge distal femoral osteotomy to realign the knee. 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. 8600 Rockville Pike Our retrospective study aims to evaluate the outcomes and analyze survivorship of the distal femoral osteotomy until eventual conversion to knee arthroplasty. Indications and Contraindications Indications Moderate corrections up to 10 degrees for opening wedge Larger corrections from 12 to 27 degrees for closing wedge Lateral compartment mild to moderate osteoarthritis Lateral condyle cartilage lesions (with or without cartilage restoration) Unable to load your collection due to an error, Unable to load your delegates due to an error. Orthop Traumatol Surg Res. Epub 2019 Mar 26. An official website of the United States government. The distal femur was resected en bloc . At an average 99-month followup, 83% were reported as satisfactory and three were converted to TKA. A survivorship analysis. 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]. However, osteoarthritis continues to progress and multiple arthroscopic or open procedures may be required despite a successful osteotomy. Knee Society knee scores improved from 43 to 78. Survivorship at 5 years, with conversion to arthroplasty as the endpoint, was 74% in the arthritis group and 92% in the joint preservation group. Some distal femoral osteotomies involve taking out bone where you let the . In general, patients who wish to remain relatively high impact, especially laborers or patients who are still pretty active, or in younger patients, a distal femoral osteotomy would be preferred over a total knee replacement. 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. 2021 Jul;34(8):816-821. doi: 10.1055/s-0039-3400742. Dr. La Prade had just moved to Vail and I was his 2nd patient @ The Steadman Clinic. This answers all my questions! There are often many symposia and debates at national and international meetings on this topic. The authors reported 18 of 19 patients were satisfied. 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. PROMs and complications were analyzed using random-effects modeling to identify differences in outcomes as a function of surgical technique. Clin Sports Med. Conclusions: To perform a systematic review and meta-analysis for patients with valgus knee deformity undergoing DFO to determine differences in patient-reported outcome measures (PROMs), complications, and survival rates, comparing CW versus OW DFO. 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. Patients who are bowlegged are in varus alignment. Careers. 2015 Jun;473(6):2009-15. doi: 10.1007/s11999-014-4106-8. Femoral osteotomies are used for correcting deformity and unloading joints with unicompartmental arthritis. Primary total hip arthroplasty can become a challenge for the experienced surgeon in the setting of a deformed proximal femur or with re [16] reported on 21 medial closing-wedge osteotomies in 19 patients with a mean age of 57 years at 2- to 12-year followup. Two knees (two patients) underwent a medial closing-wedge osteotomy and were excluded from the present study. The frequency of hardware removal was higher than we expected and indicates that this should be discussed with patients preoperatively. Healy WL, Anglen JO, Wasilewski SA, Krackow KA. 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. In the arthritis group, the mean IKDC total score improved from 47 (SD, 15) preoperatively to 67 (SD, 10) postoperatively. 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. The unloading osteotomy is especially useful in the young, active patient as an adjunct procedure for cartilage repair. After successful application of the plate and screws re-open the osteotomy allowing compression at the fracture site. All I can say is Dr. La Prade did an amazing job and I am not limited in any of my activites. In general, it is felt that younger patients definitively should have a distal femoral osteotomy when it is indicated, whereas older patients may equally benefit from a distal femoral osteotomy or a total knee replacement, depending upon their overall activity levels, if they have other medical problems, and if their bone is relatively osteopenic (softer than normal). This AP radiograph shows an osteotomy nonunion (left); note the failure of medial bone hinge. 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. (3) What are the nonunion, complication, and reoperation rates after lateral opening-wedge osteotomy? The remaining 31 knees (82%) in 30 patients comprised the study population. 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. 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. Saithna A, Kundra R, Getgood A, Spalding T. Opening wedge distal femoral varus osteotomy for lateral compartment osteoarthritis in the valgus knee. Knee Surg Relat Res. Jacobi M, Wahl P, Bouaicha S, Jakob RP, Gautier E. Distal femoral varus osteotomy: problems associated with the lateral open-wedge technique. The heights of . Time to radiographic union, complications, and reoperations were recorded. and transmitted securely. 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 ~. Characteristics of the arthritis and the joint preservation groups. The average follow-up duration was 43 31 months and the need for further procedures (such as arthroscopic adhesiolysis, hardware removal, revision osteotomy and eventual progression to arthroplasty) was identified with relation to complications. 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. 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. 15. However, as a result of the small sample size, it was not appropriate to test the change from preoperatively to followup statistically; thus, no p value is given. Survivorship at 10, 15, and 20 years was 90%, 79%, and 21.5%, respectively. The ContourLock distal femoral osteotomy plates are designed to work in conjunction with the Osteotomy Instrument System. The https:// ensures that you are connecting to the [7] reported on 21 knees in 20 patients with a mean 11-year followup. Distal femoral osteotomy can be technically demanding and various complications are reported in the literature. An improved method of preoperative templating and refinement of the intraoperative technique may improve this. For cartilage patients the cut off is slightly lower at 3-4 degrees of valgus. 4010 W. 65th St. If patients have knock kneed knees and arthritis this can be a very effective surgery and delay the need for a knee replacement. Data is temporarily unavailable. Saithna et al. 2021. Accessibility You may be trying to access this site from a secured browser on the server. Improvement in pain and function of this procedure at intermediate-term followup has been acceptable [1, 2, 6, 7, 12, 13, 20]. 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. They also reported two cases of loss of correction, one infection, and one nonunion. It is completed through an anteromedial longitudinal incision, approximately 10 cm above the patella extending distally to its upper third. Between 2000 and 2010, we performed 40 distal femoral osteotomies. 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). Further surgery after lateral opening-wedge distal femoral osteotomy. Terry GC, Cimino PM. After successful application of the plate and screws re-open the osteotomy allowing compression at the fracture site. 11. 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. Epub 2019 Nov 27. The ContourLock distal femoral osteotomy plates are designed to work in conjunction with the Osteotomy Instrument System. Patient preoperative and postoperative pain and function were assessed using the International Knee Documentation Committee (IKDC) score. Besides, it is still controversial whether patellofemoral arthritis should be considered as a contraindication to performing a DFO, as well as in HTO. Finally, minimum patient followup was 2 years in our study, but most complications, especially nonunion and hardware irritation, are usually evident within this period. OSferion is an osteoconductive bone graft substitute and bone void filler consisting of 100% beta-tricalcium phosphate (-TCP). Readers are encouraged to always seek additional information, including FDA-approval status, of any drug or device prior to clinical use. The second is in patients who have arthritis on the outside of the knee and are too young for a standard partial knee replacement. In addition, there are some patients who may have a cartilage replacement surgery and/or a lateral meniscal transplant with their ACL reconstructions. Would you like email updates of new search results? The 5-year survival with the endpoint of conversion to arthroplasty was 79%. Dr Charlie Peterson, Orthopedic Surgeon & Sports Medicine Specialist. Phil Downer, M.D | Knee Surg Sports Traumatol Arthrosc. Knee Surg Sports Traumatol Arthrosc. Methods: We performed a retrospective review of 78 open-wedge distal femoral osteotomies done on 74 patients at our institution between 2001 and 2011. 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. Orthopedic Surgeon & Sports Medicine Specialist 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. Distal femoral varus osteotomy for painful genu valgum. 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. 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. Epub 2014 Dec 24. Inclusion criteria consisted of studies reporting outcomes in patients undergoing CW or OW DFO for the treatment of valgus knee deformities with symptomatic lateral compartment pathology with a minimum 2-year follow-up. 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. Seattle Shoulder Surgery | 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. The entire limb, including the iliac crest, was prepped and draped free. There are two main surgical techniques for a distal femoral osteotomy. 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. 18. 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. Further x-rays are obtained at that point to verify healing. official website and that any information you provide is encrypted This transfer bias is important to remember when reviewing our results. 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. Routine radiographs of the osteotomy site were obtained at followups as well as postoperative long-limb alignment radiographs when possible. Cameron, James I. MD1; McCauley, Julie C. MPHc2; Kermanshahi, Arash Y. MD3; Bugbee, William D.

EDINA- CROSSTOWN OFFICE 2022 Aug 24;9:100436. doi: 10.1016/j.ejro.2022.100436. The aim of this study was to report the occurrence of . 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. The success rates for lateral meniscal transplants and cartilage resurfacing procedures are much less if the valgus alignment is not corrected with the surgical procedure (or before it). In a simplified technique, an opening wedge osteotomy is performed originating from the distal femoral diaphyseal-metaphyseal flare, avoiding surgical exposure to the medial side of the distal femoral region. Closed intramedullary osteotomies of the femur. 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. This site needs JavaScript to work properly. Epub 2018 Oct 5. SPECIMENS: Multiple cultures from the right ankle. 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. Conclusion: Distal femoral osteotomy is an acceptable surgical option for the young patient with severe unicompartmental knee osteoarthritis and malalignment. Oda T, Maeyama A, Yoshimura I, Ishimatsu T, Miyazaki K, Tachibana K, Yoshimitsu K, Yamamoto T. BMC Musculoskelet Disord. Some error has occurred while processing your request. 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. I can run, bike, & climb mountains. 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. your express consent. HHS Vulnerability Disclosure, Help 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. 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. DFOs can be performed with a medial closing wedge (CWDFO) or a lateral opening wedge (OWDFO) technique. Routine closure was then performed and the patient was placed into a ROM brace. Eagan, MN 55121, I struggled with my knee for 18 months - having gone from 10,000 steps a day to only walking as needed. 2017 Mar;45(4):909-914. doi: 10.1177/0363546516676266. may email you for journal alerts and information, but is committed
