Background: Evidence on the management of and outcomes from periprosthetic fractures about a total ankle replacement (TAR) are limited. The purpose of this study was to develop an algorithm for the management of patients with postoperative periprosthetic fractures about a TAR. Methods: This was a retrospective analysis of patients undergoing a TAR from 2007 through 2017 with a subsequent periprosthetic fracture >4 weeks from index surgery. Implant stability was defined radiographically and intraoperatively where appropriate. Univariate and multivariate analyses were used to identify differences in outcomes. Thirty-two patients were identified with a remote TAR periprosthetic fracture with an average follow-up of 26 months (range, 3-104 months). Results: Most fractures were located about the medial malleolus (62.5%); the majority of fractures (75%) were deemed to have stable implants. Fractures of the talus always had unstable implants and always required revision TAR surgery (100%, P = .0002). There was no difference in patient-reported outcomes between stable and unstable fractures at an average of 36 months. In a multivariate analysis, fracture location (talus), less time to fracture, and implant type were found to be predictive of unstable implants ( P < .001). Implant stability was independently associated with the need for revision surgery ( P < .049). Nonoperative treatment was independently associated with treatment failure ( P < .001). Conclusion: The majority of stable fractures about a TAR required operative fixation. Management with immobilization was fraught with a high rate of subsequent surgical intervention. We found that fractures about the talus required revision TAR surgery or arthrodesis. Level of Evidence: Level III, retrospective cohort study.

Category: Ankle Introduction/Purpose: Total ankle replacements (TAR) are an increasingly popular option for the management of tibiotalar arthritis. Periprosthetic fracture is an uncommon but challenging complication of patients undergoing arthroplasty. Evidence on the management of and outcomes from periprosthetic fractures about a TAR are limited. The purpose of this study was to evaluate patients with postoperative periprosthetic fractures about a TAR and determine clinical outcomes of these patients following operative fixation. Additionally, we propose an algorithm for the management of these patients. Methods: We retrospectively analyzed 400 patients who underwent TAR from 2007 through 2017. Charts were reviewed and patients with postoperative fractures were selected for inclusion. Patients with a fracture >4 weeks from index surgery were considered candidates for inclusion. Patients with intraoperative fractures were excluded. Univariate analyses were used to identify differences in outcomes. Results: 32 patients were identified with a postoperative periprosthetic fracture about a TAR. Average age was 65.3 years. Average time to fracture was 39.5 months while average follow up from fracture was 26 months. Fractures were primarily located about the medial malleolus (60.6%). 76.8% of fractures were deemed to be stable (Table 1); 75% of these fractures were managed with ORIF or IMN, while 21% of these fractures were treated with immobilization. 80% of patients with stable fractures treated with immobilization ultimately required surgical intervention. 24.2% of fractures were deemed to be unstable. Fractures about the talus were always unstable and always required revision TAR surgery (100%, p= 0.0002). Conclusion: This retrospective review demonstrates that the majority of periprosthetic fractures about a TAR involve the medial malleolus. Additionally, the majority of stable fractures about a TAR required operative fixation. Despite attempts at nonoperative management, management with immobilization is fraught with a high rate of subsequent surgical intervention. Fractures about the talus should be treated with revision TAR surgery or arthrodesis. Based on these findings, we propose an algorithm for the management of patients with a periprosthetic fracture about a TAR.

Background: Neutral ankle alignment along with medial and lateral support are paramount to the success of total ankle replacement (TAR). Fibula, intra-articular medial malleolus, and supramalleolar tibia osteotomies have been described to achieve these goals; however, the literature is scant with outcomes and union rates of these osteotomies performed concomitant to TAR. The purpose of this study was to describe our results. Methods: A retrospective review was performed to identify patients who had a concomitant tibia, fibula, or combined tibia and fibula osteotomy at the same time as TAR. Routine radiographs were used to assess osteotomy union rates and changes in alignment. Outcomes questionnaires were evaluated preoperatively and at most recent follow-up. Twenty-six patients comprising 4% of the total TAR cohort were identified with a mean follow-up of 3.9 years. Results: There were 12 combined tibia and fibula osteotomies, 9 isolated tibia osteotomies, and 5 isolated fibula osteotomies. The union rate for these osteotomies was 92%, 100%, and 100%, respectively. Mean coronal alignment improved from 15.2 to 2.1 degrees ( P < .001). There was significant improvement in patient-reported outcome scores, including Short Form-36, Short Musculoskeletal Function Assessment, and visual analog scale pain. There was 1 failure in the study. Conclusion: These data demonstrate successful use of tibia, fibula, or combined tibia and fibula osteotomies at the same time as TAR in order to gain neutral ankle alignment. The overall union rate was 96% with significant improvement in alignment, pain, and patient-reported outcomes. We believe concomitant osteotomies can be considered a successful adjunctive procedure to TAR. Level of Evidence: Level III, retrospective comparative series.

Background: Total ankle replacement (TAR) and ankle fusion are effective treatments for end-stage ankle arthritis. Comparative studies elucidate differences in treatment outcomes; however, the literature lacks evidence demonstrating what outcomes are important to patients. The purpose of this study was to investigate patients’ experiences of living with both a TAR and ankle fusion. Methods: This research study used qualitative description. Individuals were selected from a cohort of patients with TAR and/or ankle fusion (n = 1254). Eligible patients were English speaking with a TAR and contralateral ankle fusion, and a minimum of 1 year since their most recent ankle reconstruction. Surgeries were performed by a single experienced surgeon, and semistructured interviews were conducted by a single researcher in a private hospital setting or by telephone. Ankle Osteoarthritis Scale (AOS) scores, radiographs, and ancillary surgical procedures were collected to characterize patients. Themes were derived through qualitative data analysis. Results: Ten adults (8 men, 2 women), ages 59 to 90 years, were included. Average AOS pain and disability scores were similar for both surgeries for most patients. Participants discussed perceptions of each reconstructed ankle. Ankle fusions were considered stable and strong, but also stiff and compromising balance. TARs were considered flexible and more like a “normal ankle,” though patients expressed concerns about their TAR “turning” on uneven ground. Individuals applied this knowledge to facilitate movement, particularly during a first step and transitioning between positions. They described the need for careful foot placement and attention to the environment to avoid potential challenges. Conclusion: This study provides insight into the experiences of individuals living with a TAR and ankle fusion. In this unusual but limited group of patients, we found that each ankle reconstruction was generally perceived to have different characteristics, advantages, and disadvantages. Most participants articulated a preference for their TAR. These findings can help clinicians better counsel patients on expectations after TAR and ankle fusion, and improve patient-reported outcome measures by better capturing meaningful outcomes for patients.

Context: Ankle syndesmotic injuries present a significant challenge for athletes due to prolonged disability and recovery periods. The optimal management of these injuries and rates of return to sport in athletes remains unclear. Objective: The purpose of this study was to evaluate return to sport for athletes after ankle syndesmotic injuries. Data Source: The electronic databases MEDLINE, EMBASE, and PubMed were searched for relevant studies from database inception to January 15, 2017, and pertinent data were abstracted. Study Selection: Only studies reporting return-to-sport rates after ankle syndesmotic injuries were included. Study Design: Systematic review. Level of Evidence: Level 4. Data Extraction: Two reviewers extracted data from the included studies, which were stored in a standardized collection form (Microsoft Excel). Recorded data included demographics (eg, author, year of publication, study design), descriptive statistics (eg, patient age, percentage male, number of athletes, sample size), and outcomes (eg, time to return to sport, proportion of those who returned to sport, the self-reported questionnaire the Olerud-Molander Ankle Score). Results: A total of 10 studies and 312 patients with ankle syndesmotic injuries were included in this systematic review. The rate of return to preinjury or any injury level of sport after ankle syndesmotic injuries was 93.8% ± 1.2% and 97.6% ± 1.5%, respectively, for the corresponding 7 and 3 studies that reported this characteristic. The mean time to return to sport was 46.4 days (range, 15.4-70 days), with 55.2 ± 15.8 and 41.7 ± 9.8 days for operative and nonoperative management, respectively. Conclusion: This systematic review found a high rate of return to any as well as preinjury level of sport after ankle syndesmotic injury in both operative and nonoperative treatment groups. However, further high-level studies are required to compare operative and nonoperative treatment groups associated with return to sport after ankle syndesmotic injury.

End Stage

Background: Outcomes of total ankle replacement for the treatment of end-stage ankle arthritis continue to improve. Debate continues whether a mobile-bearing total ankle replacement (MB-TAR) or a fixed-bearing total ankle replacement (FB-TAR) is superior, with successful outcomes reported long term for MB-TAR and at intermediate- to long-term follow-up for newer generation FB-TAR. Although comparisons between the 2 total ankle designs have been reported, to our knowledge, no investigation has compared the 2 designs with a high level of evidence. This prospective, randomized controlled trial conducted at a single institution compares patient satisfaction, functional outcomes, and radiographic results of the mobile-bearing STAR and the fixed-bearing Salto-Talaris in the treatment of end-stage ankle arthritis. Methods: Between November 2011 and November 2014, adult patients with end-stage ankle osteoarthritis failing nonoperative treatment were introduced to the study. With informed consent, 100 patients (31 male and 69 female, average age 65 years, range 35-85 years) were enrolled; a demographic comparison between the 2 cohorts was similar. Exclusion criteria included inflammatory arthropathy, neuropathy, weight exceeding 250 pounds, radiographic coronal plane deformity greater than 15 degrees, or extensive talar dome wear pattern (“flat-top talus”). Prospective patient-reported outcomes, physical examination, and standardized weightbearing ankle radiographs were obtained preoperatively, at 6 and 12 months postoperatively, and then at yearly intervals. Data collection included visual analog pain score, Short Form 36, Foot and Ankle Disability Index, Short Musculoskeletal Functional Assessment, and American Orthopaedic Foot & Ankle Society ankle-hindfoot score. Surgeries were performed by a nondesign team of orthopedic foot and ankle specialists with total ankle replacement expertise. Statistical analysis was performed by a qualified statistician. At average follow-up of 4.5 years (range, 2-6 years) complete clinical data and radiographs were available for 84 patients; 7 had incomplete data, 1 had died, 4 were withdrawn after enrolling but prior to surgery, and 4 were lost to follow-up. Results: In all outcome measures, the entire cohort demonstrated statistically significant improvements from preoperative evaluation to most recent follow-up with no statistically significant difference between the 2 groups. Radiographically, tibial lucency/cyst formation was 26.8% and 20.9% for MB-TAR and FB-TAR, respectively. Tibial settling/subsidence occurred in 7.3% of MB-TAR. Talar lucency/cyst formation occurred in 24.3% and 2.0% of MB-TAR and FB-TAR, respectively. Talar subsidence was observed in 21.9% and 2.0% of MB-TAR and FH-TAR, respectively. Reoperations were performed in 8 MB-TARs and 3 FH-TARs, with the majority of procedures being to relieve impingement or treat cysts and not to revise or remove metal implants. Conclusion: With a high level of evidence, our study found that patient-reported and clinical outcomes were favorable for both designs and that there was no significant difference in clinical improvement between the 2 implants. The incidence of lucency/cyst formation was similar for MB-TAR and FH-TAR for the tibial component, but the MB-TAR had greater talar lucency/cyst formation and tibial and talar subsidence. As has been suggested in previous studies, clinical outcomes do not necessarily correlate with radiographic findings. Reoperations were more common for MB-TAR and, in most cases, were to relieve impingement or treat cysts rather than revise or remove metal implants. Level of Evidence: Level I, prospective randomized study.

Talar Fractures

Category: Ankle; Ankle Arthritis; Trauma Introduction/Purpose: Although total ankle replacement (TAR) for the treatment of end-stage ankle arthritis has been shown to have excellent radiographic and clinical outcomes, there is a risk for complications such as periprosthetic fractures. While periprosthetic fractures of the tibia are well described in the literature, little is known about such fractures involving the talus. The purpose of this case series is to describe the radiographic findings and surgical management of talar fractures sustained after placement of total ankle prostheses. Methods: We retrospectively reviewed 489 patients who underwent total ankle replacement from June 2015 to March 2019, and identified five cases (2 males, 3 females, average age 45.7 years) in which patients sustained a periprosthetic fracture of the talus. All patients presented symptomatically with ankle pain during postoperative follow-up, and fractures of the talus were confirmed on computed tomography (CT) imaging. One patient had psoriatic arthritis and four patients had primary osteoarthritis of the ankle. CTs were reviewed to confirm location and pattern of the fracture, as well as related pathology such as osteolysis and subsidence. Hospital charts and operative reports were reviewed to record patient demographics and postoperative management including reoperations. Results: Overall the incidence of talar fractures was 1% (5/489) and all occurred in implants with a talar stem (4 INBONE II, 1 Salto Talaris). All fractures extended from the stem of the talar component into the subtalar joint, with one case of a non- displaced fracture. Osteolysis surrounding the talar stem was observed in all cases, with subsidence of the talar component observed in four out of five patients on CT. All five patients presented symptomatically and underwent reoperation (1 revision of talar component with ORIF, 3 subtalar fusions, 1 tibiotalar fusion). Conclusion: The findings in this case series suggest that periprosthetic fractures of the talus following total ankle replacement is a possible complication of stemmed implants and is associated with poor clinical outcomes requiring reoperation. Therefore, a periprosthetic fracture of the talus should be considered in a patient with unexplained pain and evidence of radiographic osteolysis around the stemmed component. [Table: see text]

Osteotomy Technique

Background: The current techniques for medial malleolar osteotomy may lead to posterior tibial tendon injury and have a high rate of malunion. Purpose: To describe a novel partial step-cut medial malleolar osteotomy technique and evaluate its technical feasibility and its advantages compared with traditional methods. Study Design: Case series; Level of evidence, 4. Methods: The novel technique consisted of osteotomy of the anterior one-third to two-thirds of the medial malleolus. A total of 19 ankles (18 patients) with osteochondral lesions of the talus underwent the novel osteotomy technique before osteochondral reconstruction. All patients were evaluated for more than 2 years. Radiographs were analyzed for postoperative displacement and malunion, and postoperative ankle function was evaluated according to the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scale and the visual analog scale (VAS) for pain. Results: The partial step-cut osteotomy technique was able to provide adequate intra-articular exposure without disturbing the posterior tibial tendon. The 19 ankles healed at a mean of 7.3 ± 1.5 weeks (range, 6-12 weeks). There was slight incongruence in 4 ankles, with a displacement of 1.0 ± 0.1 mm proximally and 0.3 ± 0.1 mm medially. The mean postoperative AOFAS and VAS scores improved compared with preoperatively, from 54.2 ± 12.1 to 84.6 ± 6.6 and from 6.4 ± 1.0 to 1.8 ± 1.3, respectively ( P < .001 for both). No intraoperative tendon injuries were observed. Conclusion: Results indicated that partial step-cut osteotomy is a reliable and effective method for providing enough exposure, avoiding displacement after reduction, and not disturbing the anatomic structures behind the medial malleolus.

Background: Restoration of ankle alignment is important in total ankle arthroplasty (TAA), but sagittal alignment of the talar component is less studied than coronal sagittal. Little has been published on the importance of sagittal talar alignment in TAA. The radiographic talar component inclination was hypothesized to be predictive of TAA survival, subsidence, and functional outcomes. Methods: A retrospective review of the Vancouver End-Stage Ankle Arthritis Database was performed on all TAAs at a single center over 11 years utilizing 1 of 2 implants. Talar component inclination (TCI) angles were measured and standard descriptive statistics were completed with a survival analysis. Inter- and intraobserver reliability were determined. Postoperative TCI angles were analyzed against several definitions of TAA survival and patient-reported outcome measures from the database. A total of 109 TAAs satisfied inclusion and exclusion criteria. Results: A postoperative talar component inclination angle greater than 22 degrees was associated with talar component anterior subsidence, defined as a change in that angle of 5 degrees or more between postoperative and last available radiographs. This was still significant after adjusting for confounders: age, gender, body mass index, and presence of inflammatory arthritis. All measured angles had good inter- and intraobserver reliability. Conclusion: Surgeons should avoid dorsiflexing the talar prosthesis during TAA, which hypothetically diminishes the ankle critical dorsiflexion range. This may cause anterior talar undercoverage in terminal dorsiflexion and may edge load the talar prosthesis, predisposing to anterior subsidence. Elevated TCI was a simple and reliable radiographic measurement to predict long-term TAA outcome due to predictable anterior subsidence of the talar prosthesis. Level of Evidence: Level III, retrospective comparative series.

Background There are few reports in the literature detailing the arthroscopic treatment of multidirectional instability of the shoulder. Hypothesis Arthroscopic management of symptomatic multidirectional instability in an athletic population can successfully return athletes to sports with a high rate of success as determined by patient-reported outcome measures. Study Design Case series; Level of evidence, 4. Methods Forty patients (43 shoulders) with multidirectional instability of the shoulder were treated via arthroscopic means and were evaluated at a mean of 33.5 months postoperatively. The mean patient age was 19.1 years (range, 14-39). There were 24 male patients and 16 female patients. Patients were evaluated with the American Shoulder and Elbow Surgeons and Western Ontario Shoulder Instability scoring systems. Stability, strength, and range of motion were also evaluated with patient-reported scales. Results The mean American Shoulder and Elbow Surgeons score postoperatively was 91.4 of 100 (range, 59.9-100). The mean Western Ontario Shoulder Instability postoperative percentage score was 91.1 of 100 (range, 72.9-100). Ninety-one percent of patients had full or satisfactory range of motion, 98% had normal or slightly decreased strength, and 86% were able to return to their sport with little or no limitation. Conclusion Arthroscopic methods can provide an effective treatment for symptomatic multidirectional instability in an athletic population.

Lisfranc Injuries

Background: While surgery is indicated in Lisfranc fracture-dislocations, the natural history and optimal management of minimally displaced injures are unclear. The aim of this study was to define the rate of subsequent displacement and to determine the clinical outcome after conservative treatment of minimally displaced Lisfranc injuries. Methods: Over a 5-year period (2011-2016), 26 consecutive patients with minimally displaced Lisfranc injuries presenting to a single university teaching hospital were identified retrospectively using hospital electronic records. Patient demographics, injury mechanism, and radiological outcomes were recorded. Patient-reported outcome scores (PROMS) were collated at least 1 year postinjury and included the American Orthopaedic Foot & Ankle Society (AOFAS) midfoot score and Manchester Oxford Foot Questionnaire (MOXFQ). Results: The rate of displacement was 54% (14/26). The median time to displacement was 18 days (range, 2-141 days). Forty-six percent (12/26) of the Lisfranc injuries remained minimally displaced after 12 weeks of conservative treatment. Initial weightbearing status was not associated with the risk of subsequent displacement ( P = .9). At a mean follow-up of 54 months, PROMS were comparable between patients whose injury remained minimally displaced and those that required surgery for further displacement, despite the delay to surgery (AOFAS 78.0 vs 75.9, MOXFQ 24.8 vs 26.3, P > .1). Conclusion: There was a high rate of displacement after initial conservative management of the minimally displaced Lisfranc injuries. Subsequent surgical management of displaced injuries resulted in outcomes comparable to those that remained minimally displaced. Level of Evidence: Level III, retrospective comparative series.
