Background: We investigated the association between hindfoot residual malalignment assessed on weightbearing computed tomography (WBCT) images and the development of periprosthetic cysts (PPCs) after total ankle replacement (TAR). We hypothesized that PPCs would be found predominantly medially in the varus configuration and laterally in the valgus configuration. Methods: Cases of primary TAR with available WBCT imaging of the ankle were included in this retrospective study. The location of the PPC was marked and the following volumes were calculated: total (TCV), medial (MCV), central (CCV), and lateral (LCV) cyst volumes. Hindfoot alignment was measured as Foot and Ankle Offset (FAO), with 95% confidence intervals (95% CIs) calculated to define varus (<95% CI) and valgus (>95% CI) groups. Cyst volumes were compared between these 2 groups. The American Orthopaedic Foot & Ankle Society (AOFAS) score at the time of the WBCT was also retrieved. Receiver operating characteristic (ROC) curves were used to determine FAO thresholds for predicting an increased risk of PPC. Results: Forty-eight TARs (mean follow-up, 44.6 months) were included, 81% of which had at least 1 PPC. The mean FAO was 0.12% (95% CI, –1.12 to 1.36). Patients with greater residual malalignment ( P < .001) and those with longer follow-up ( P < .001) presented with increased TCV. In varus cases, the MCV was greater than the LCV ( P = .042), with a threshold FAO value of −2.75% or less predicting an increased MCV. In valgus cases, the LCV was greater than the MCV ( P = .049), with a FAO threshold value of 4.5% or more predicting an increased LCV. Conclusion: In this series, the PPC volume after primary TAR significantly correlated with postoperative hindfoot malalignment and longer follow-up. Level of Evidence: Level III, retrospective comparative series.

The Difference

Category: Ankle, Ankle Arthritis Introduction/Purpose: Peri-prosthetic cysts (PPC) in Total Ankle Replacement (TAR) are a common failure cause but the mechanisms of their development remains unclear. One possible explanation could be hindfoot malalignment and subsequent unequal distribution of load inside the joint. However, how residual malalignment influences the evolution of PPC remains unclear. Computed tomography (CT) has demonstrated superiority on conventional radiography in the follow up of PPC. Weight Bearing CT (WBCT), by combining 3D imaging and weight bearing measurements seems a valid tool to investigate this further. The objective for this work was to study the effects of residual hindfoot deformity on the distribution of PPC in the coronal plane. We hypothesized that cysts would be found predominantly medially in varus configuration, and laterally in valgus configuration. Methods: Retrospective comparative study, ethics committee approved. Forty-eight cases of TAR were included, with relevant demographics. Inclusion criteria were cases of primary TAR with available WBCT imaging of their ankle as part of normal follow up. Exclusion criteria were subsequent implant revision or cyst grafting. In each case, the localization and size of PPC’s were documented and their volume calculated by approximation of the closest ellipsoid. Hindfoot alignment was evaluated by the percentage Foot Ankle Offset (FAO) (foot-length normalized 3D ratio between the midline of the foot and the center of the ankle) using a WBCT dedicated semi-automatic software. The mean FAO value with 95%CI for the population was calculated. The difference in medial and lateral cyst volume defined by their position relative to the median axis in the coronal plane was compared in varus and valgus cases by a Mann-Whitney non-parametric test for unpaired samples. Results: Demographic distributions of the series were 32% female, mean age 65 (45-85) years. Mean FAO value was 0.12% (95%CI -1.09 to 1.33). Mean follow up was 43 months (6 to 239). The mean total cyst volume per case was 1190,7 mm3. In varus cases (defined by FAO<-1.09%), the volume of medial cysts was greater than laterally by a mean 197 mm3, whereas in valgus cases (defined by FAO>1.33%), the volume of lateral cysts was greater than medially by a mean 332 mm3. The difference was statistically significant (p<0.05). There was a weak, significant positive correlation (r=0.25, p<0,001) between FAO and total cyst volume and a moderate, significant correlation (r=0,56, p<0,001) between time to follow up and total cyst volume. Conclusion: Our hypothesis was confirmed. Periprosthetic cysts volume in this series of primary TAR was found to be relatively greater medially in postoperative varus configurations and vice-versa laterally in valgus. This confirms a possible correlation between the direction of residual hindfoot malalignment and the coronal localization of PPC in TAR, although this is certainly not the only pathophysiologic factor involved in PPC onset. Weightbearing CT may be helpful in Total Ankle Replacement follow up, in order to early detect PPC development and possibly to identify situations at risk of a more rapid evolution.

Category: Ankle Arthritis Introduction/Purpose: Ankle arthritis is a highly limiting pathology that causes pain and functional limitation with subsequent deterioration of quality of life. With recent advances in surgical instrumentation and techniques, prosthetic replacement of the ankle has proved to be a valid alternative to arthrodesis with comparable outcomes. The purpose of this study was to evaluate clinical and radiological findings in a transfibular total ankle replacement with two years follow-up. Methods: This prospective study included 59 patients who underwent transfibular total ankle arthroplasty from May 2013 to December 2015. The mean age was 51.6 ± 13.4 years. All patients were followed for at least 24 months postoperative with an average follow-up of 42.0 ± 23.5 months. Patients were assessed clinically and radiologically preoperatively and at 6, 12, and 24 months postoperatively. Results: At 24 months, patients demonstrated statistically significant improvement in the American Orthopaedic Foot and Ankle Society score from 33.6 to 88.1 (P<0.01), VAS scale from 79.3 to 14.0 (P<0.01) and SF-12 Physical and Mental Composite Scores from 29.9 and 44.6 to 74.4 and 95.3, respectively (P<0.01). Ankle dorsiflexion and plantarflexion improved from 5.5 and 8.8 degrees to 24.2 and 20.0 degrees, respectively (P<0.01). Radiographically, patients demonstrated neutral alignment of the ankle with a tibio-talar ratio of 34.9 ± 9.2 and hindfoot alignment view angle of 1.2 ± 7.0 degrees. No patient demonstrated any radiographic evidence of tibial or talar lucency at 24 months. Seven patients underwent reoperation for removal of symptomatic hardware; one patient developed a postoperative prosthetic infection requiring placement of an antibiotic spacer. Conclusion: This study demonstrates that transfibular total ankle replacement is a safe and effective option for the patients for ankle arthritis with improvements in patient-reported outcomes, range of motion, and radiological parameters. However, further studies are required to determine the mid- and long-term performance of these implants.

Category: Ankle Introduction/Purpose: With ankle replacements gaining credibility there is a small subset of patients that might benefit from a conversion of an ankle fusion to a replacement. There is not much in the literature about conversions and we began this study without having any specific data regarding success and expectations we could provide to the patients. Our hypothesis was that for the correct indication a conversion of an ankle fusion to a total ankle replacement might do as well as a primary total ankle replacement. Methods: Twenty five patients presented to the senior author with either ongoing ankle pain after a fusion, or increasing pain after a period of relative comfort after an ankle fusion. All patients came specifically with the desire to discuss a conversion to an ankle replacement. Exclusion criteria included a history of Diabetes, peripheral neuropathy, excision of either malleoli at the time of fusion, pantalar fusion and neurovascular compromise. This study was conducted in compliance and approved with a local IRB. Outcomes were evaluated pre-operatively and post-operatively with the Veterans Rand Health Survey (VR-12), Ankle Osteoarthritis Scale (AOS), Visual Analog Scale (VAS) Pain scale and the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Score forms. A patient satisfaction survey was distributed to all patients and results were tabulated. Average follow up for outcome scores 23.77 months (range 4 – 74.78 months). Results: All ankle fusion conversions done at our center were included; no patients were lost to follow-up. Twenty-five patients(19 females) with the mean age of 63.7 months(36.55-75.83) were followed with a mean follow-up of 22.19 months(4–74.78 months). The mean AOFAS improved pre-operatively 26.25(8.0-56.0) to the latest follow-up of 78(77-100). VR-12 Mental improved from 52.24(34.81-72.46) to 56.13(28.4–72.31), and Physical 21.88(13.34-35.79) to 36.49(19.82-50.39) pre-operatively to post-operatively, respectively. The AOS Pain improved: 533.33(243-898) to the latest follow-up 215.86(15 -641); AOS Disability: 628.67(306-900) to the latest follow-up 221.64(2-612). Given patients have minimal to no dorsiflexion(DF) and plantarflexion(PF) with an ankle fusion, the range of motion increased with the affected ankle. Patients have a DF of 9.47degrees(2-15) and PF of 21.53degrees(12-35). Overall patients were satisfied with their results: 76.81/100. Conclusion: This is a small study with reasonable short follow-up, but the evidence show very satisfactory functional outcomes after a conversion of an ankle fusion to a total ankle replacement. Patient selection is extremely important. Long-term follow-up will show whether the longevity of these replacements compare to primary replacements.

Background: The purpose of this study was to describe the technique of endoscopic resection of talocalcaneal coalition (TCC) by using 2 posterior portals and to report the outcomes of endoscopic resection of different types and sites of TCC. Methods: An interventional prospective study was conducted on 20 feet in 18 consecutive patients who were diagnosed by computed tomography to have TCC for which nonoperative treatment had failed and endoscopic resection was performed. The patients were divided into groups according to the site of the coalition (middle facet or posterior facet) and according to type (fibrous, cartilage, or bony). The mean follow-up period was 26 months (range, 6-36). Results: The average preoperative American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot score was 57.7 (range, 40-65), and the average preoperative visual analog scale (VAS) score was 7.8 (range, 6-8). The average postoperative AOFAS hindfoot score was 92.4 (range, 85-98; P < .01). The average postoperative VAS score was 2.4 (range, 1-4). All patients showed no recurrence on postoperative lateral and Harris-Beath X-ray until the end of the study. Conclusions: Endoscopic resection of TCC was an effective and useful method for the treatment of talocalcaneal coalition. It provided excellent outcomes with no recurrence in this short-term study. Resection of the fibrous type had a better outcome than resection of cartilage and bony types. Endoscopic resection of the posterior coalition had a better outcome than resection of the middle coalition. Level of Evidence: Level III, comparative study.

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.

Category: Ankle Arthritis Introduction/Purpose: Hemophilia is a rare hematological disease associated with spontaneous joint hemorrhaging causing hemophilic arthropathy. Symptoms comprise joint pain and deformity, paired with loss of function. In the presence of advanced joint deterioration, therapeutic options are confined to either arthroplasty or arthrodesis. For the ankle, the latter is still referred to as the procedure of choice. However - in light of its capacity to reduce pain while preserving ankle motion - total ankle replacement (TAR) has recently gained acceptance as an alternative. The aim of this study was to investigate the mid- to long-term results of TAR in hemophilic ankle arthropathy. Methods: Seventeen TARs were implanted between 1998 and 2012 (mean age: 43 years). Preoperative demographic and disease specific data, complications and revision surgeries were recorded. With a mean follow-up of 9.3 years (range, 2.2-17.8) implant survival was estimated using Kaplan-Meier analysis. Follow-up assessment of 12 TARs was performed after 9.6 years (5 lost to follow-up). Satisfaction and pain scales, the AOFAS hindfoot-score, and the SF-36 were obtained to assess clinical outcome. Radiographic evaluation of pre- and follow-up radiographs was conducted. Results: Three cases (17.6%) had undergone TAR removal secondary to loosening at an average interval of 7.5 years. The estimated implant survival was 94% at 5, 85% at 10, and 70% at 15 years (95% CI, 11.9-17.7). The mean estimated implant survival was 14.77 years (95% CI, 11.9-17.7). The mean level of satisfaction was 76%, and of pain 2/10 (VAS). ROM had increased significantly (p=0.037). The SF-36 summary scores were comparable to those of a matched standard population. The AOFAS hindfoot-score averaged 81/100 points. Conclusion: TAR is a viable treatment option for advanced hemophilic ankle arthropathy. Based on the herein presented follow- up, implant survival compares to that of non-hemophilic populations. Clinical mid- to long-term results are favorable. However, the majority of follow-up radiographs revealed component loosening and/or periprosthetic lucency. Considering the study population’s young age and specific risk factors, need for revision surgery secondary to symptomatic component loosening may arise.

Retrospective Comparative Study

Background: Surgeons frequently add an Achilles tendon lengthening or gastrocnemius recession to increase dorsiflexion following total ankle replacement. Previous studies have looked at the effects of these procedures on total tibiopedal motion. However, tibiopedal motion includes motion of the midfoot and hindfoot as well as the ankle replacement. The current study examined the effects of Achilles tendon lengthening and gastrocnemius recession on radiographic tibiotalar motion at the level of the prosthesis only. Methods: Fifty-four patients with an average of 25 months follow-up after total ankle replacement were divided into 3 groups: (1) patients who underwent Achilles tendon lengthening, (2) patients who had a gastrocnemius recession, (3) patients with no lengthening procedure. Tibiotalar range of motion was measured on lateral dorsiflexion-plantarflexion radiographs using reference lines on the surface of the implants. Results: Both Achilles tendon lengthening and gastrocnemius recession significantly increased tibiotalar dorsiflexion when compared to the group without lengthening. However, the total tibiotalar range of motion among the 3 groups was the same. Interestingly, the Achilles tendon lengthening group lost 11.7 degrees of plantarflexion compared to the group without lengthening, which was significant. Conclusion: Both Achilles tendon lengthening and gastrocnemius recession increased radiographic tibiotalar dorsiflexion following arthroplasty. Achilles tendon lengthening had the unexpected effect of significantly decreasing plantarflexion. Gastrocnemius recession may be a better choice when faced with a tight ankle replacement because it increases dorsiflexion without a compensatory loss of plantarflexion. Level of Evidence: Level III, retrospective comparative study.

Background: Anterior cruciate ligament reconstruction (ACLR) with hamstring autograft has gained popularity. However, an unpredictably small graft diameter has been a drawback of this technique. Smaller graft diameter has been associated with increased risk of revision, and increasing the number of strands has been reported as a successful technique to increase the graft diameter. Purpose: To compare failure rates of 5-strand (5HS) and 6-strand (6HS) hamstring autograft compared with conventional 4-strand (4HS) hamstring autograft. We describe the technique in detail, supplemented by photographs and illustrations, to provide a reproducible technique to avoid the variable and often insufficient 4HS graft diameter reported in the literature. Study Design: Cohort study; Level of evidence, 3. Methods: We retrospectively reviewed prospectively collected data of all primary hamstring autograft ACLRs performed at our institution with a minimum 2-year follow-up and 8.0-mm graft diameter. A total of 413 consecutive knees met the study inclusion and exclusion criteria. The study population was divided into 5HS and 6HS groups as well as a 4HS control group. The primary outcome was failure of ACLR, defined as persistent or recurrent instability and/or revision ACLR. Results: The analysis included 224, 156, and 33 knees in the 5HS, 6HS, and 4HS groups, respectively. The overall ACLR failure rate in this study was 11 cases (8%): 5 cases for 5HS, 3 cases for 6HS, and 3 cases for 4HS. No statistically significant differences were found among groups ( P = .06). The mean graft diameter was 9 mm, and the mean follow-up was 44.27 months. Conclusion: The 5HS and 6HS constructs have similar failure rates to the conventional 4HS construct of 8.0-mm diameter and are therefore safe and reliable to increase the diameter of relatively smaller hamstring autografts. We strongly recommend using this technique when the length of the tendons permits to avoid failures reportedly associated with inadequate graft size.

Category: Ankle, Ankle Arthritis Introduction/Purpose: Total ankle replacement as a valid treatment for end stage ankle arthritis, is gaining popularity and every year there is an increasing number of procedures. With revision rates as high as 21% at 5 years and 43% at 10 years there is a need for understanding and reporting the outcome of revision ankle replacement. Our aim was to study the patient reported outcomes following revision TAR with a minimum of 2 year follow up. Methods: All patients that underwent a revision total ankle replacement between 2012 and 2016 were included in the study. All patients received a post-operative questionnaire comprising of MOX-FQ score, EQ-5D (UK) and Foot and Ankle outcomes scores (FAOS) and patients satisfaction questionnaire with a minimum of 2 years follow up. Results: 32 patients had a revision total ankle replacement between 2012 and 2016. 2 patients were deceased therefore 30 patients were included in the study. 5 patients declined participation for completing questionnaires. We received 21 (66%) completed questionnaires. The mean MOX-FQ average domain score for pain was 58.8, walking/standing 65.8 and social function was 48.2. The mean FAOS scores were 50.7 for pain, 50.6 for symptoms, 54.9 for ADL and 28.2 for quality of life. The mean overall health score today for EQ-5D was 67.8/100. 45% of patients were satisfied with the pain relief and return to sports and recreation obtained following the operation, 48% were satisfied with the improved in daily activities. 52% were overall satisfied with the results from surgery. Conclusion: Revision total ankle replacement gives overall satisfactory results demonstrated from patients reported outcomes at a minimum of 2 years following surgery.

Background: The most frequent complication after Weil osteotomies is a floating toe deformity, but there are no reports about its effect on the patient. In this study, we analyzed the consequences of floating toe deformities after the performance of a modified Weil osteotomy (MWO) or a modified Weil osteotomy with interphalangeal fixation (MWOIF). Methods: We performed a retrospective review with a prospective follow-up of 50 patients (98% women, 120 rays) who underwent MWO (65 rays) or MWOIF (55 rays), with a mean age of 54 ± 12 years and a minimum follow-up of 4 years (mean of 6 years). We analyzed the presence of floating toe deformity in MWO and MWOIF and the outcomes measured by the subjective satisfaction, Lower Extremity Functional Scale (LEFS), American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score, and quality of prehension force between patients with or without floating toe deformity. Results: The mean floating toe incidence was of 57%, with no significant difference between operative techniques (48% MWO, 67% MWOIF; P = .053). Our analysis did not show differences in satisfaction, LEFS and AOFAS scores, or grip strength between the group of patients with or without floating toes. Conclusion: The presence of a floating toe deformity was more frequent than generally believed but did not have a meaningful impact on the patient’s satisfaction or functional outcomes measured by the AOFAS and LEFS scales. There was no clear correlation between operative technique, floating toe, and quality of prehension force. Level of Evidence: Level III, retrospective comparative series.
