Open Versus Arthroscopic Ankle Arthrodesis: A Comparative Study

A retrospective review was undertaken for 36 patients who underwent ankle arthrodesis. Nineteen patients underwent an arthroscopic ankle arthrodesis, and 17 patients underwent an open arthrodesis. Only patients with limited angular deformities were suitable candidates for an arthroscopic arthrodesis. The open arthrodesis group inclusion criteria were defined by the maximum coronal and sagittal plane deformity in the arthroscopic group. Perioperative parameters were compared and analyzed. Arthroscopic ankle arthrodesis yielded comparable fusion rates to open ankle arthrodesis, with significantly less morbidity, shorter operative times, shorter tourniquet times, less blood loss, and shorter hospital stays. Arthroscopic ankle arthrodesis is a valid alternative to traditional open arthrodesis of the ankle for selected patients with ankle arthritis.

Consensus in chronic ankle instability: Aetiology, assessment, surgical indications and place for arthroscopy

Ankle sprains are the most common injuries sustained during sports activities. Most ankle sprains recover fully with non-operative treatment but 20-30% develop chronic ankle instability. Predicting which patients who sustain an ankle sprain will develop instability is difficult. This paper summarises a consensus on identifying which patients may require surgery, the optimal surgical intervention along with treatment of concomitant pathology given the evidence available today. It also discusses the role of arthroscopic treatment and the anatomical basis for individual procedures.

Evidence-Based Indications for Ankle Arthroscopy

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.

Minimally invasive surgical treatment for chronic ankle instability: a systematic review.

AbstractPurpose The purpose of this study was to determine the evidence-based support for the treatment for chronic ankle instability (CAI) using minimally invasive surgery (MIS) techniques.MethodsA systematic comprehensive review of the literature was performed on 4 September 2015 using PubMed, EMBASE, Cochrane databases and Web of Science along with the two search concepts: lateral ligament of the ankle (patients) and minimally invasive surgical procedure (intervention). Articles of clinical study on MIS for CAI were included in this review and classified into four MIS categories (arthroscopic repair, non-arthroscopic minimally invasive repair, arthroscopic reconstruction and non-arthroscopic minimally invasive reconstruction) based on the adopted surgical procedure. Included articles were reviewed and assigned a classification according to the research method quality of evidence (Level I–V evidence). Analysis of these studies was then conducted to provide a grade of recommendation for each MIS category.ResultsThe systematic literature review generated 430 articles, and 33 articles met our inclusion criteria. The highest recommendation was Grade C (poor-quality evidence) to support the use of the arthroscopic repair, arthroscopic reconstruction and non-arthroscopic minimally invasive reconstruction. Insufficient evidence was currently available to make any recommendation (Grade I) for non-arthroscopic minimally invasive repair category.ConclusionsDespite recent increases in publications on MIS for the treatment for CAI, there was currently poor quality of evidence that was insufficient to allow a high grade of recommendation to support the use of the MIS. This paper should stimulate those surgeons performing higher quality studies in the form of prospective and preferably randomized comparative studies that will be necessary to allow better recommendations for the treatment for CAI with MIS. The present study showed thorough evidence-based recommendation for the clinical use of the MIS based on the comprehensive review of the literature.Level of evidenceSystematic review, Level IV.

Arthroscopic anterior talofibular ligament repair for lateral instability of the ankle

AbstractAlthough several arthroscopic procedures for lateral ligament instability of the ankle have been reported recently, it is difficult to augment the reconstruction by arthroscopically tightening the inferior extensor retinaculum. There is also concern that when using the inferior extensor retinaculum, this is not strictly an anatomical repair since its calcaneal attachment is different to that of the calcaneofibular ligament. If a ligament repair is completed firmly, it is unnecessary to add argumentation with inferior extensor retinaculum. The authors describe a simplified technique, repair of the lateral ligament alone using a lasso-loop stitch, which avoids additionally tighten the inferior extensor retinaculum. In this paper, it is described an arthroscopic anterior talofibular ligament repair using lasso-loop stitch alone for lateral instability of the ankle that is likely safe for patients and minimal invasive. Level of evidence Therapeutic study, Level V.

Ankle arthroscopy in industrial injuries of the ankle

Industry-related injuries to the foot and ankle are not uncommon. These cases are often difficult to evaluate with respect to degree of damage and even more difficult to quantitate with regard to functional impairment. This article represents an attempt to determine the role of ankle arthroscopy in the evaluation of ankle injuries that involve compensation or liability. A retrospective review was conducted. The study group consisted of 40 patients who underwent a total of 42 arthroscopic procedures. The patients were evaluated with regard to the mechanism of injury and clinical manifestations. Pain and swelling were the most common preoperative symptoms. The majority of patients had pain localized to the lateral and anterolateral ankle. There were a high percentage of positive bone scans that correlated well with bone pathology but poorly with soft-tissue pathology. Computed tomography (CT) scans were equivalent to tomograms in the demonstration of bone pathology. Follow-up was obtained in 24 patients. At least 50% of the patients had some improvement in their symptoms. Thirty-three percent believed there was no change, and 17% said they were worse. Over 70% of the patients were able to return to work, although 20% had to change their occupation. Fifteen percent were considered disabled. In patients without a specific diagnosis, ankle arthroscopy was helpful in establishing a diagnosis.(ABSTRACT TRUNCATED AT 250 WORDS)

Percutaneous Ankle Reconstruction of Lateral Ligaments (Perc-Anti RoLL).

Summary Chronic ankle instability following ankle sprains causes pain and functional problems such as recurrent giving way. If non-operative treatments fail, then operative ankle stabilization may be required to improve pain and function. Operative options include both anatomic repair and reconstruction techniques. Anatomic repair techniques utilize pre-existing ligament remnants that are either reattached or tightened to improve stability of the ankle. If pre-existing ligament structures have been damaged beyond repair or are insufficient to allow repair, then it is appropriate to choose an anatomic reconstructive technique. These procedures have traditionally been performed using open techniques and have been successful in restoring function and decreasing pain. In 2005, an open anatomic reconstruction technique using a gracilis Y-graft and Inside-out technique was reported with good results. In the current paper we describe a Percutaneous Reconstruction of the Lateral Ligaments (Perc-Anti RoLL), which is a new minimally invasive surgical technique for anatomic reconstruction of the lateral ligaments of the ankle that utilizes the anatomic Y-graft and Inside-out technique. The Perc-Anti RoLL technique can be performed percutaneously using fluoroscopic guidance.

Percutaneous Ankle Reconstruction of Lateral Ligaments

Chronic ankle instability following ankle sprains causes pain and functional problems such as recurrent giving way. Within the 3 ligaments of the lateral ligament complex, 80% of patients tear the anterior talofibular ligament (ATFL), whereas the other 20% of patients tear the ATFL and calcaneofibular ligament (CFL). Rarely, the posterior talofibular ligament is involved. An incidence of 10% to 30% of patients will fail conservative treatment and result in chronic ankle instability that may require surgical treatment. To date, numerous open surgical procedures for anatomic repair or reconstruction of ATFL and/or CFL provide good clinical results.

Osteochondral Allograft: Proceedings of the International Consensus Meeting on Cartilage Repair of the Ankle

Background: The evidence supporting best practice guidelines in the field of cartilage repair of the ankle is based on both low quality and low levels of evidence. Therefore, an international consensus group of experts was convened to collaboratively advance toward consensus opinions based on the best available evidence on key topics within cartilage repair of the ankle. The purpose of this article is to report the consensus statements on “Osteochondral Allograft” developed at the 2017 International Consensus Meeting on Cartilage Repair of the Ankle. Methods: Seventy-five international experts in cartilage repair of the ankle representing 25 countries and 1 territory were convened and participated in a process based on the Delphi method of achieving consensus. Questions and statements were drafted within 11 working groups focusing on specific topics within cartilage repair of the ankle, after which a comprehensive literature review was performed and the available evidence for each statement was graded. Discussion and debate occurred in cases where statements were not agreed upon in unanimous fashion within the working groups. A final vote was then held, and the strength of consensus was characterized as follows: consensus, 51% to 74%; strong consensus, 75% to 99%; and unanimous, 100%. Results: A total of 15 statements on osteochondral allograft reached consensus during the 2017 International Consensus Meeting on Cartilage Repair of the Ankle. One achieved unanimous support and 14 reached strong consensus (greater than 75% agreement). All statements reached at least 85% agreement. Conclusions: This international consensus derived from leaders in the field will assist clinicians with osteochondral allograft as a treatment strategy for osteochondral lesions of the talus.
