Epidemiology and Treatment of Surgical Infection after Ankle Arthroscopy: A Systematic Review. J Clin Med 2024; 13:983. [PMID: 38398296 PMCID: PMC10889786 DOI: 10.3390/jcm13040983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2023] [Revised: 01/30/2024] [Accepted: 02/03/2024] [Indexed: 02/25/2024] Open
Abstract
Background: Ankle arthroscopy is indicated for both diagnosis and treatment of a large spectrum of common ankle disorders. It has certain advantages over the open procedure; however, it is important to recognize that there are some complications associated with it. Infections after this procedure are quite uncommon, with an overall estimated incidence of 2%. Given the low incidence of infections after ankle arthroscopy, not a great deal of literature on the topic has been published. The present review aims to provide an overview of the incidence, diagnosis, and treatment of infections after ankle arthroscopy. Methods: A systematic review of the literature indexed in the PubMed, MEDLINE, and Cochrane Library databases using search term "ankle arthroscopy infections" was performed in November 2023. No restrictions were applied concerning the date of publication. The Preferred reporting items for systematic reviews and meta-analyses (PRISMA) were followed. Among all surgical operations for the treatment of ankle and foot pathologies, we included articles with a described superficial or deep infection after ankle arthroscopy. Results: The search resulted in 201 studies. Only 21 studies met our inclusion criteria, and they were included in this systematic review. We evaluated 1706 patients who underwent 1720 arthroscopic tibiotalar procedures at an average age of 42 years old. Out of the 1720 procedures, 41 (2%) were complicated by infection. We divided infectious complications into superficial (68%; 28/41) and deep (32%; 13/41) infections. The most common pathogen isolated was Staphylococcus aureus. Arthroscopic arthrodesis was found to be the most affected by deep infections. Conclusions: Infection after ankle arthroscopy is an uncommon complication. Superficial infections were successfully treated with antibiotics, while surgical debridement, arthroscopic drainage, and intravenous antibiotics were necessary in cases of deep infections. Considering the amount of information on pathogens associated with knee and shoulder infections, there is still a lack of literature on pathogens associated with ankle infections, which makes their management difficulty.

Abstract
Despite the increasing popularity of total ankle replacement, ankle arthrodesis remains the gold standard for the treatment of end-stage ankle arthritis. Historically, open techniques have been utilized for ankle arthrodesis. There have been many variations and techniques described, including transfibular, anterior, medial, and miniarthrotomy. Inherent disadvantages to these open techniques include postoperative pain, delayed or nonunion, wound complications, shortening, prolonged healing times, and prolonged hospital stays. Arthroscopic ankle arthrodesis provides the foot and ankle surgeon with an alternative to the traditional open techniques. Arthroscopic ankle arthrodesis has demonstrated faster union rates, decreased complications, reduced postoperative pain, and shorter hospital stays.

Arthroscopic vs open ankle arthrodesis: A prospective case series with seven years follow-up. World J Orthop 2021; 12:1016-1025. [PMID: 35036344 PMCID: PMC8696599 DOI: 10.5312/wjo.v12.i12.1016] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2021] [Revised: 06/27/2021] [Accepted: 12/10/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The osteoarthritis of the ankle, although less common than other joints, is associated with severe functional limitation. Surgical options are ankle arthroscopic debridement, osteotomies, ankle arthrodesis and ankle arthroplasty. Ankle arthroplasty is increasingly used thanks to the new implants design, but ankle arthrodesis still represents the most used technique and it can be performed arthroscopically or with an open procedure.
AIM To compare mid-term results of arthroscopic vs open ankle arthrodesis of patients affected by end-stage ankle arthritis.
METHODS This study enrolled 23 patients, which underwent ankle arthrodesis. The patients were divided into 2 groups: group A (open procedure; n = 11) and group B (arthroscopic procedure, n = 12), the two groups were homogeneous with regard to age and body mass index (P = 0.347). The American Orthopaedic Foot and Ankle score (AOFAS), Freiburg Ankle score (FAS) and visual analogue scale for pain intensity were evaluated preoperatively, at six months and at final follow-up of 7.6 years in group A and 7.3 years in group B (P = 0.364).
RESULTS Patients in the arthroscopic group showed better results at six-month follow-up compared to the open group at the AOFAS (group A, 62.2; group B, 78.5; P < 0.05) and the FAS (group A, 61.1; group B, 70.3; P = 0.015) scores. Pain relief was achieved in both groups at six-month follow-up (group A, 1.4; group B, 0.9; P = 0.162). Both open and arthroscopic groups showed improved clinical outcomes from baseline to final follow-up (P > 0.05). Hospital stay was shorter in group B than in group A (P = 0.001). More complications were reported in the open group than in the arthroscopic group (P = 0.459).
CONCLUSION The arthroscopic and the open arthrodesis are valid and safe options for the treatment of ankle arthritis on the basis of clinical outcomes at 7 years follow-up. Moreover, the arthroscopic treatment shows faster improvement at six-month follow-up in comparison with the open group.

A case of osteophyte excision and arthroscopic arthrodesis for tarsal tunnel syndrome with traumatic osteoarthritis of the ankle. Int J Surg Case Rep 2020; 76:510-516. [PMID: 33207421 PMCID: PMC7596014 DOI: 10.1016/j.ijscr.2020.10.053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Accepted: 10/15/2020] [Indexed: 12/04/2022] Open
Abstract
We successfully treated tarsal tunnel syndrome (TTS) accompanied with traumatic osteoarthritis of the ankle. Osteophyte excision for the TTS and arthroscopic for the osteoarthritis was effective for even TTS with traumatic osteoarthritis of the ankle. There were many advantages in arthroscopic ankle arthrodesis, compared with open ankle arthrodesis.
Introduction There are some reports of tarsal tunnel syndrome (TTS) entrapment/impingement from bony factors, including exostosis and fragment, but there are no reports on TTS with traumatic osteoarthritis of the ankle that were treated with osteophyte excision for TTS and arthroscopic arthrodesis for osteoarthritis of the ankle. Presentation of case A 61-year-old woman with left trimalleolar fracture had undergone surgery 3 years earlier and was referred to our hospital for further investigation of persistent left ankle pain and numbness around the left medial malleolus and plantar aspect of the foot. Clinical examination demonstrated plantar hypesthesia and a positive Tinel’s sign at the tarsal tunnel. Imaging showed severe osteoarthritic change in the ankle and an osteophyte of the posteromedial distal tibia that appeared to be impinging on the tibial nerve. We performed arthroscopic ankle arthrodesis, which is less invasive than the open procedure, with removal of the osteophyte as the cause of TTS. Tarsal tunnel exploration revealed a large osteophyte pushing on the tibial nerve, and the osteophyte was removed. Discussion About 8 weeks after surgery, bony union was achieved. At the 2-year follow-up visit, the patient could perform daily activities with almost no pain or numbness. This case offers further insight into the management of TTS with traumatic osteoarthritis of the ankle. Conclusion We report here successful treatment of a rare case of tarsal tunnel syndrome (TTS) accompanied with traumatic osteoarthritis of the ankle, treated with osteophyte excision for the TTS and arthroscopic for the osteoarthritis.

Abstract
Background We have classified ankle arthrodesis when using an external fixator into four types based on the deformity and defect. Each of the four types of technique have been evaluated retrospectively. Materials and methods Thirty-three lower limb segments in 30 patients (average age 49 years) were treated by ankle arthrodesis using an external fixator in our institution. We classified the pre-treatment problems into four types and adjusted the surgical treatment accordingly: type I—no bone defect, no or mild deformity; type II—no bone defect, severe deformity; type III—bone defect with the possibility to shorten acutely after resection of the pathological focus; and type IV—bone defect but without the ability to shorten acutely after resection of the pathological focus. Type I problems were treated with curettage of ankle cartilage and bone graft with external fixation. Type II problems were treated with mobilisation using an external fixation after performing a type I ankle arthrodesis. Type III problems were treated with ankle arthrodesis using acute shortening and distraction. Type IV problems were treated with ankle arthrodesis using bone transport. Results All patients had secure ankle fusion and were able to bear total weight in walking on completion of treatment. The mean external fixation period was 96 days in type I, 181 days in type II, 231 days with lengthening in type III and IV. The complications included re-fracture in three cases, deformity at the lengthening site in one, delayed union in one, and infection at fusion site in one. Conclusion We have strategized ankle arthrodesis procedures using an external fixator into four groups in order to align the surgical technique with the pre-treatment problem. Our classification can help decide the appropriate operative method when using an external fixator, especially for difficult cases. How to cite this article Matsubara H, Watanabe K, Takata M, et al.

Abstract
Arthroscopic ankle arthrodesis provides an alternative to open techniques. Advancements in arthroscopic techniques and instrumentation have made the procedure easier to perform. Arthroscopic ankle arthrodesis has demonstrated faster rates of union, fewer complications, reduced postoperative pain, and shorter hospital stays. Sound surgical techniques, particularly with regard to joint preparation, are critical for success. Comorbidities such as increased body mass index, history of smoking, malalignment, and posttraumatic arthritis should be considered when contemplating arthroscopic ankle arthrodesis. Although total ankle replacement continues to grow in popularity, arthroscopic ankle arthrodesis remains a viable alternative for management of the end-stage arthritic ankle.

Ankle arthrodesis: A systematic approach and review of the literature. World J Orthop 2016; 7:700-708.

Abstract
Ankle arthrodesis is a common treatment used for patients with end-stage ankle arthritis (ESAA). The surgical goal of ankle arthrodesis is to obtain bony union between the tibia and talus with adequate alignment [slight valgus (0°-5°)], neutral dorsiflexion, and slight external rotation positions) in order to provide a pain-free plantigrade foot for weightbearing activities. There are many variations in operative technique including deferring approaches (open or arthroscopic) and differing fixation methods (internal or external fixation). Each technique has its advantage and disadvantages. Success of ankle arthrodesis can be dependent on several factors, including patient selection, surgeons’ skills, patient comorbidities, operative care, etc. However, from our experience, the majority of ESAA patients obtain successful clinical outcomes. This review aims to outline the indications and goals of arthrodesis for treatment of ESAA and discuss both open and arthroscopic ankle arthrodesis. A systematic step by step operative technique guide is presented for both the arthroscopic and open approaches including a postoperative protocol. We review the current evidence supporting each approach. The review finishes with a report of the most recent evidence of outcomes after both approaches and concerns regarding the development of hindfoot arthritis.

Abstract
PURPOSE To study the safety and efficiency of posterior arthroscopic ankle arthrodesis. METHODS Ten fresh-frozen human lower leg specimens without evidence of previous surgery to the foot and ankle were selected. Arthroscopic debridement of the tibiotalar joint was performed in all specimens using a standardized protocol. Anatomical dissections were regarded the gold standard for safety analysis. To evaluate the efficacy of the posterior ankle arthroscopic arthrodesis, the debrided articular tibiotalar parts were resected and subsequently analysed using Image-analysis software, Image J (Wayne Rasband, National Institutes of Health, Bethesda, MD). RESULTS In none of the specimens, iatrogenic damage was detected during the anatomical dissection following the posterior ankle arthroscopic procedure. A total talar joint surface area of 95 % and total tibial joint surface area of 96 % was addressed during the arthroscopic debridement. CONCLUSIONS The posterior ankle arthroscopic arthrodesis can be regarded safe and is also highly effective in the debridement of cartilage, resulting in optimal biology for fusion to occur. Therefore, this new arthroscopic technique potentially will diminish existing non-union rates for the fusion of the ankle joint.

Abstract
Opinions differ regarding the surgical treatment of posterior calcaneal exostosis. After failure of conservative treatment, open surgical bursectomy and resection of the calcaneal prominence is indicated by many investigators. Clinical studies have shown high rates of unsatisfactory results and complications. Endoscopic calcaneoplasty (ECP) is a minimally invasive surgical option that can avoid some of these obstacles. ECP is an effective procedure for the treatment of patients with posterior calcaneal exostosis. The endoscopic exposure is superior to the open technique and has less morbidity, less operating time, fewer complications, and the disorders can be better differentiated.

Abstract
BACKGROUND Ankle arthrodesis is an accepted treatment for patients with advanced disabling tibiotalar arthritis, mostly in osteoarthritis, rheumatoid, and posttraumatic arthritis. No detailed reports have been published regarding the use of arthroscopy for the treatment of the end-stage hemophilic ankle. The purpose of this article is to report the results of arthroscopic ankle arthrodesis in hemophilic arthropathy of the ankle. METHODS Ten patients (10 ankle joints) who underwent arthroscopically assisted ankle arthrodesis for the treatment of end-stage hemophilic A arthritis were enrolled in this study. The rate of ankle fusion, incidence of complications, and clinical rating by the Morgan system were analyzed. RESULTS In this series, the fusion rate was 100%, and patients achieved bone fusion as shown by radiographs. The average time to fusion was 10.5 weeks. Superficial wound infection occurred in 1 patient. According to the Morgan system, there were 8 (80%) good to excellent results and 2 (20%) fair results. All patients were satisfied with the outcome of the operation. CONCLUSIONS Arthroscopic ankle arthrodesis was an effective alternative to open technique with established advantages in hemophilic arthropathy.

Abstract
PURPOSE To determine the incidence of nonunion after isolated arthroscopic ankle arthrodesis. METHODS Electronic databases and relevant peer-reviewed sources, including OvidSP/Medline (http://ovidsp.tx.ovid.com) and Google, were systematically searched for the terms "arthroscopic ankle arthrodesis" AND "nonunion". Additionally, we manually searched common American, British, and European orthopaedic and podiatric scientific literature for relevant articles. Studies were eligible for inclusion only if they included the following: isolated ankle arthrodesis, greater than 20 ankles, minimum mean follow-up of 12-months, a 2-portal anterior arthroscopic approach, fixation with 2 or 3 large-diameter cannulated cancellous screws, and the nonunion rate with no restriction on cause. RESULTS After considering all the potentially eligible articles, 7 (25.9%) met the inclusion criteria. A total of 244 patients (244 ankles)-148 (60.7%) male and 96 (39.3%) female patients, with a weighted mean age of 49.2 years-were included. For those studies that specified the exact follow-up, the weighted mean was 24.1 months. A total of 21 nonunions (8.6%) were reported, with 14 (66.7%) being symptomatic and requiring further intervention. CONCLUSIONS The results of this systematic review reveal an acceptable incidence of nonunion of 8.6%. However it is important to recognize that of these nonunions, 66.7% were symptomatic. This supports the belief that regardless of approach, nonunion of an ankle arthrodesis is problematic. In light of this finding, additional prospective studies are warranted to compare directly the incidence of nonunion between open, minimum incision, and arthroscopic approaches with a variety of fixation constructs.

Abstract
BACKGROUND Arthroscopic ankle arthrodesis (AAA) is a recognised salvage procedure for end-stage arthritis. Its reported disadvantages include a high rate of re-operation for symptomatic prominence of metalwork. We propose that the use of a headless screw would reduce this re-operation rate. METHODS We reviewed 32 AAAs, using the Acutrak™6/7 mm headless screw fixation system, to determine peri-operative parameters and complication rates. RESULTS At an average of 22 months follow-up, 28 (88%) had united radiologically. There were 2 stable fibrous non-unions not requiring further intervention. Of the other 2, one was successfully revised using an open technique, and the other patient died of unrelated causes. There were no other complications in this series, with no cases of metalwork removal for prominence or pain. CONCLUSIONS Using a headless screw fixation for arthroscopic ankle arthrodesis prevents symptomatic metalwork prominence and the requirement for removal.

Abstract
PURPOSE Ankle arthrodesis (AAD) and total ankle replacement (TAR) are the major surgical treatment options for severe ankle arthritis. There is an ongoing discussion in the orthopaedic community whether ankle arthrodesis or ankle fusion should be the treatment of choice for end stage osteoarthritis. The purpose of this study was to compare the participation in sports and recreational activities in patients who underwent either AAD or TAR for end-stage osteoarthritis of the ankle. METHODS A total of 41 patients (21 ankle arthrodesis /20 TAR) were examined at 34.5 (SD18.0) months after surgery. At follow-up, pre- and postoperative participation in sports and recreational activities has been assessed. Activity levels were determined using the ankle activity score according to Halasi et al. and the University of California at Los Angeles (UCLA) activity scale. Clinical and functional outcome was assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score. The percentage of patients participating in sports and recreational activities, UCLA score and AOFAS score were compared between both treatment groups. RESULTS In the AAD group 86% were active in sports preoperatively and in the TAR group this number was 76%. Postoperatively in both groups 76% were active in sports (AAD, p = 0.08). The UCLA score was 7.0 (± 1.9) in the AAD group and 6.8 (± 1.8) in the TAR group (p = 0.78). The AOFAS score reached 75.6 (± 14) in the AAD group and 75.6 (± 16) in the TAR group (p = 0.97). The ankle activity score decrease was statistically significant for both groups (p = 0.047). CONCLUSIONS Our study revealed no significant difference between the groups concerning activity levels, participation in sports activities, UCLA and AOFAS score. After AAD the number of patients participating in sports decreased. However, this change was not statistically significant.

Abstract
Understanding when to proceed with an arthroscopy of the ankle and foot can at times be difficult. Proper preoperative planning will ensure that the correct surgical procedure is selected. Although most surgeons can determine the correct diagnosis and treatment options for the patient based on the subjective and objective examinations, advanced imaging and diagnostic injections are useful tools in difficult cases.

Abstract
Compared with traditional open arthrodesis, arthroscopic ankle arthrodesis has been associated with similar rates of fusion, decreased time to union, decreased pain, shorter hospital stay, earlier mobilization, reliable clinical results, and fewer complications. The aim of this case-control study was to analyze cost differences between outpatient arthroscopic and inpatient open ankle arthrodesis. To this end, the authors analyzed 20 ankle arthrodesis procedures: 10 performed by one surgeon on an inpatient basis using an open approach, and 10 performed by another surgeon on an outpatient basis arthroscopically. Patient age, body mass index, tourniquet time, length of stay, complications, days to clinical union, and insurance type, as well as charges and reimbursements for the surgeons and the hospital or surgery center were abstracted from the records. Statistically significant differences were observed between the outpatient arthroscopic and inpatient open arthrodesis groups for total site charges ($3898 +/- 0.00 versus $32,683 +/- $12,762, respectively, P < .0001), reimbursement to the surgeon ($1567 +/- $320 versus $1107 +/- $278, respectively, P = .003), and reimbursement to the hospital or ambulatory surgery center ($1110 +/- $287 versus $8432 +/- $2626, respectively); the ratio of hospital/surgery center charges to hospital/surgery center reimbursements was 28.48% for the inpatient arthroscopic group and 25.80% for the inpatient open arthrodesis group. Outpatient arthroscopic ankle arthrodesis, compared with inpatient open ankle arthrodesis, appears to be less expensive for third party payers, and surgeons are paid more, whereas hospitals and ambulatory surgical centers get paid a greater proportion of the charges that they bill.

Abstract
PURPOSE The purpose of this study was to review the literature to provide a comprehensive description of the Level of Evidence available to support the surgical technique of ankle arthroscopy for the current generally accepted indications and assign a grade of recommendation for each of them. METHODS A comprehensive review of the literature was performed (in August 2008) by use of the PubMed database. The abstracts from these searches were reviewed to isolate literature that described therapeutic studies investigating the results of different ankle arthroscopic treatment techniques. All articles were reviewed and assigned a classification (I-IV) of Level of Evidence. An analysis of the literature reviewed was used to assign a grade of recommendation for each current generally accepted indication for ankle arthroscopy. RESULTS There exists fair evidence-based literature (grade B) to support a recommendation for the use of ankle arthroscopy for the treatment of ankle impingement and osteochondral lesions and for ankle arthrodesis. Ankle arthroscopy for ankle instability, septic arthritis, arthrofibrosis, and removal of loose bodies is supported with only poor-quality evidence (grade C). Treatment of ankle arthritis, excluding isolated bony impingement, is not effective and therefore this indication is not recommended (grade C against). Finally, there is insufficient evidence-based literature to support or refute the benefit of arthroscopy for the management of synovitis and fractures (grade I). CONCLUSIONS There exists adequate evidence-based literature to support the surgical technique of ankle arthroscopy for most current generally accepted indications; however, further studies in this area are needed. LEVEL OF EVIDENCE Level IV, systematic review.

Abstract
Numerous techniques for ankle arthrodesis have been reported since the original description of compression arthrodesis. From the early 1950s to the mid 1970s, external fixation was the dominant technique utilized. In the late 1970s and 1980s, internal fixation techniques for ankle arthrodesis were developed. In the 1990s, arthroscopic ankle arthrodesis was developed for ankle arthrosis with minimal or no deformity. The open technique is still widely used for ankle arthrosis with major deformity. For complex cases that involve nonunion, extensive bone loss, Charcot arthropathy, or infection, multiplanar external fixation with an Ilizarov device, with or without a bone graft, may achieve successful union. The fusion rate in most of the recently published studies is 85% or greater, and may depend on the presence of infection, deformity, avascular necrosis, and nonunion.

Abstract
Arthroscopic ankle arthrodesis provides the foot and ankle surgeon with an alternative to traditional open techniques. Advancements in arthroscopic techniques and instrumentation have made the procedure easier to perform. Advantages include faster rates of union, decreased complications, reduced postoperative pain, shorter hospital stays, minimal loss of length of the lower limb, and minimal clinical deformity or shapechanges to the ankle. This article reviews the literature on the subject and discusses the procedure's indications and contraindications, and surgical technique. It concludes that while total ankle replacement continues to grow in popularity, arthroscopic ankle arthrodesis is a viable alternative for management of the end-stage arthritic ankle.

Abstract
Posterior calcaneal exostosis treatment modalities showed many controversial opinions. After failure of the conservative treatment, surgical bursectomy and resection of the calcaneal exostosis are indicated by many authors. But clinical studies also show a high rate of unsatisfactory results with a relative high incidence of complications. The minimal surgical invasive technique by an endoscopic calcaneoplasty (ECP) could be an option to overcome some of these problems. We operated on 81 patients with an age range between 25 and 55 years, 40 males and 41 females. The radiologic examination prior to surgery documented in all cases a posterior superior calcaneal exostosis that showed friction to the Achilles tendon. All patients included in the study had neither clinical varus of the hind foot nor cavus deformities. All patients had undergone a trial of conservative treatment for at least 6 months and did not show a positive response. The average follow-up was 35.3 months (12-72). According to the Ogilvie-Harris-Score, 34 patients presented good and 41 patients excellent results, while three patients showed fair results, and three patients only poor results. All the post-operative radiographs showed sufficient resection of the calcaneal spur. Only minor postoperative complications were observed. ECP is an effective and of minimal-invasive procedure for the treatment of patients with calcaneal exostosis. After a short learning curve, the endoscopic exposure is superior to the open technique has less morbidity, less operating time, and nearly no complications; moreover, the pathology can better be differentiated.

Abstract
Ankle arthrodesis is performed for the treatment of unstable, arthritic, painful, and deformed ankle joints. A wide variety of surgical options and approaches exist to treat the difficult problem of an ankle arthrodesis. In patients with only minor ankle deformity and minor bone loss arthroscopically assisted fusion is the treatment of choice. The risk for the development of a pseudarthrosis depends on clinical factors like corticoid medication, nicotine, incorrect alignment and improper mobilization. With adequate shoes the patients can remain asymptomatic for long time. Adjacent joints may show radiological degenerative changes in the long-term follow-up; however, they do not need to be clinically symptomatic. Nowadays total ankle replacement is a valid alternative. The surgical technique is demanding. Implants of the 1st and 2nd generation did not show satisfying results. The newer 3rd generation total ankle arthroplasties show promising medium-term and long-term results.

Abstract
BACKGROUND Arthroscopic ankle arthrodesis is an effective alternative to open techniques with established advantages in select patient populations. The purpose of this study was to evaluate patients who had arthroscopic ankle arthrodesis for end-stage arthritis with minimal to no deformity of the ankle and to report factors influencing union. METHODS Thirty-nine consecutive patients had arthroscopic ankle arthrodesis between 1994 and 2003. Clinical records and radiographs were retrospectively reviewed to evaluate variables that could predispose patients to nonunion. Union outcomes were correlated with etiology of arthritis, ankle deformity, medical co-morbidities, and the use of demineralized bone matrix or platelet-rich plasma. Arthroscopic ankle arthrodesis was accomplished with a consistent technique using crossed transmalleolar cannulated screw fixation. RESULTS Thirty-four of 39 patients (87.2%) achieved radiographic and clinical union. The average time to fusion was 47 (range 37 to 70) days. Poor bone quality and inherent positional ankle deformity were identified as risk factors for nonunion. Patients who smoked, had diabetes mellitus, peripheral neuropathy, or other medical co-morbidities attained ankle union in nearly all cases. In obese patients, there was an observed trend towards ankle nonunion (relative risk 5.81, p = 0.049, Fisher's Exact test). The addition of demineralized bone matrix or platelet-rich plasma did not improve the rate of ankle union. Aside from nonunion, 10 patients developed minor complications. CONCLUSION Arthroscopic ankle arthrodesis achieves high union rates, facilitates short time to union, and permits rapid patient mobility. Careful patient selection is important for the procedure. Synthetic allograft or platelet-rich plasma did not enhance the fusion rate. Obese patients showed a trend towards nonunion in this series.

Abstract
Fusion of the ankle is an established option for end-stage degenerative joint disease. The purpose of this paper is to present the surgical technique as well as our own results. AAA starts with removal of all the remaining cartilage and joint detritus. For this we routinely use a posterolateral portal. When opening the subchondral plate one must be careful not to remove too much bone. In our hands a small chisel is very helpful for this step. Fixation is performed with two screws. In 31 out of 35 patients, we were able to obtain a solid bony fusion. AAA of the ankle can be performed in patients without significant malalignment or bony defect. It is an "in-situ" fixation of the destroyed painful joint, which is not suitable for patients with neuropathic joints. Patients with secondary joint destruction due to rheumatoid arthritis can also be treated with AAA.

Abstract
We reviewed 116 patients who underwent 118 arthroscopic ankle arthrodeses. The mean age at operation was 57 years, 2 months (20 to 86 years). The indication for operation was post-traumatic osteoarthritis in 67, primary osteoarthritis in 36, inflammatory arthropathy in 13 and avascular necrosis in two. The mean follow-up was 65 months (18 to 144). Nine patients (10 ankles) died before final review and three were lost to follow-up, leaving 104 patients (105 ankles) who were assessed by a standard telephone interview. The preoperative talocrural deformity was between 22 degrees valgus and 28 degrees varus, 94 cases were within 10 degrees varus/valgus. The mean time to union was 12 weeks (6 to 20). Nonunion occurred in nine cases (7.6%). Other complications included 22 cases requiring removal of a screw for prominence, three superficial infections, two deep vein thromboses/pulmonary emboli, one revision of fixation, one stress fracture and one deep infection. Six patients had a subtalar fusion at a mean of 48 months after ankle fusion. There were 48 patients with excellent, 35 with good, 10 with fair and 11 with poor clinical results.

Abstract
Minimally invasive techniques in ankle reconstruction offer the benefits of therapeutic intervention while minimizing the risks for open incisions in this region with tenuous healing capacity. Arthroscopic arthrodesis seems to result in fusion rates that are comparable to, or faster than, procedures done with open incisions. There is an acceptably low rate of complication in high-risk patient populations. Despite the promising results to date, however, there are multiple variables contained within the published studies that impede direct comparison of their outcomes. It is difficult, therefore, to definitively assess the magnitude of benefit of a minimally invasive technique. Based on this review, support exists for a prospective, randomized trial comparing arthroscopic versus open ankle arthrodesis using a similar fusion technique in matched groups of patients. There is some evidence for the usefulness of arthroscopy as an adjunct to open lateral ligament repair or reconstruction. Arthroscopy expands our understanding of the extent of intra-articular pathology resulting from acute ligamentous trauma and the sequelae of chronic instability. It provides an opportunity for treating those lesions that may go on to cause chronic pain, thereby possibly improving patient outcomes compared with carrying out a lateral ligament stabilization procedure alone.

Abstract
Tibiotalar arthrodesis still remains the primary choice of treatment for disabling ankle arthropathy since the results of ankle arthroplasty are not yet convincing. Numerous operative techniques have been described, with an increasing trend towards the use of internal fixation and compression. Using an intramedullary compression nailing technique, 137 tibiotalar fusions were performed at our hospital. The special design of the nail allows distal interlocking in the talus and dynamic axial compression with high primary stability. With correct joint axis, only the cartilage joint surfaces were removed. For axis correction the corresponding bony joint surfaces were also resected. We also performed a dowel technique with bone grafting from the lateral malleolus. We examined 110 of the 137 patients during follow-up. A primary union could be achieved in 99 cases (90.0%). A further six cases (5.5%) healed after recompression and bone grafting. Nonunion remained in five cases (4.5%). Operative complications included one tibial shaft fracture and one hematoma. Septic complications were three superficial and eight deep infections. Sufficient pain relief after arthrodesis was reported by 70 (63.6%) patients; in 37 (33.6%) patients the symptoms remained unchanged and 3 (2.7%) patients found their pain to be worse than before the procedure. Intramedullary compression nailing is shown to be an effective technique for tibiotalar arthrodesis in severe ankle arthropathy. The main advantages of the technique are limited soft tissue damage in the ankle area and high primary stability allowing early weight bearing.

Endoscopic calcaneoplasty--rationale, surgical technique, and early results: a preliminary report. Knee Surg Sports Traumatol Arthrosc 2003; 11:190-5. [PMID: 12709784 DOI: 10.1007/s00167-003-0365-8] [Citation(s) in RCA: 47] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2002] [Accepted: 02/10/2003] [Indexed: 11/24/2022]
Abstract
We present our technique and preliminary results with endoscopic calcaneoplasty in ten patients resistant for conservative therapy for more than 6 months. All patients showed a Haglund spur on radiography; none had a cavovarus deformity. Follow-up ranged from 2 to 12 months (mean 5.2). All patients showed clinical improvement and would undergo for the procedure again. Three showed a good and seven an excellent result in Ogilvie-Harris score. Postoperative radiographic follow-up showed sufficient bone removal in all cases. Surgery lasted on average 46 min (range 28-84). There were no intra- or postoperative complications. Endoscopic calcaneoplasty is an effective minimally invasive treatment option for patients with retrocalcaneal bursitis.

Abstract
It has been generally accepted that residual cartilage and subchondral bone has to be removed in order to get bony fusion in arthrodeses. In 1998 we reported successful fusion of 11 rheumatoid ankles, all treated with percutaneous fixation only. In at least one of these ankle joint there was cartilage left. This was confirmed by arthrotomy in order to remove an osteophyte, which hindered dorsiflexion. More than 25 rheumatoid patients with functional alignment in the ankle joint have subsequently been operated on with the percutaneous technique, and so far we have had only one failure. Patients with rheumatoid arthritis are known to sometimes fuse at least their subtalar joints spontaneously, and the destructive effect of the synovitis on the cartilage could contribute to fusion when using the percutaneous technique. In a rabbit study we therefore tested the hypothesis that even a normal joint can fuse merely by percutaneous fixation. The patella was fixated to the femur with lag screw technique without removal of cartilage, and in 5 of 6 arthrodeses with stable fixation bony fusion followed. Depletion of synovial fluid seemed to be the mechanism behind cartilage disappearance. The stability of the fixation achieved at arthrodesis surgery is an important factor in determining success or failure. Dowel arthrodesis without additional fixation proved to be deleterious. A good fit of the bone surfaces appears necessary. In the ankle joint, it would be technically demanding to retain the arch-shaped geometry of the joint after resection of the cartilage. Normally the joint surfaces are resected to produce flat osteotomy surfaces that are thus easier to fit together, encouraging healing to occur. On the other hand it is considered an advantage to preserve as much subchondral bone as possible, as the strong subchondral bone plate can contribute to the stability of the arthrodesis. Ankle arthrodesis can be successfully performed in patients with rheumatoid arthritis by percutaneous screw fixation without resection of the joint surfaces. This procedure has two advantages: first, it is less surgically traumatic, second, both the arch-shaped geometry and the subchondral bone are preserved, and thus both could contribute to the postoperative stability of the construct. Intuitively, preservation of the arch-shape should increase rotational stability. The results of our experimental sawbone study indicate that the arch shape and the subchondral bone should be preserved when ankle arthrodesis is performed. The importance of this is likely to increase in weak rheumatoid bone. In a finite element study the initial stability provided by two different methods of joint preparation and different screw configurations in ankle arthrodesis, was compared. Better initial stability is predicted for ankle arthrodesis when joint contours are preserved rather than resected. Overall, inserting the two screws at a 30-degree angle with respect to the long axis of the tibia and crossing them above the fusion site improved stability for both joint preparation techniques. The question rose as to whether patients with osteoarthritis could also be operated on solely by percutaneous fixation technique. The first metatarsophalangeal joint in patients with hallux rigidus was chosen as an appropriate joint to test the percutaneous technique. In this small series we have shown that it is possible to achieve bony fusion with a percutaneous technique in an osteoarthrotic joint in humans, but failed to say anything about the fusion rate.

Abstract
SUMMARY The authors report on 15 cases of arthrodesis of the ankle joint performed by operative arthroscopy. The follow-up ranges from 1 to 3 years, and 100% of the ankle joints achieved fusion at an average of 11.5 weeks. Two of the patients had some hindfoot pain, probably because of degenerative changes to their subtalar joints, even with this short follow-up. Five patients required further surgical treatment to correct complications related to infection, symptomatic hardware, or subtalar joint arthritis. Although the fusion rate is certainly encouraging, this procedure in the senior author's hand has a significant complication rate.
