Two Year Follow up of Cadence Total Ankle Replacement

Total ankle replacement has become a viable alternative to ankle arthrodesis in the surgical management of advanced ankle arthritis. Total ankle replacement has generally been reserved for patients who are older and for those who will have a lower demand on the replacement. The purpose of the current study is to review patient outcomes, complications, and implant survival in patients younger than 55 years who underwent total ankle replacement at a single institution. A single-center chart and radiographic review was performed of consecutive patients who underwent total ankle replacement for treatment of end-stage ankle arthritis. All surgeries were performed by 1 of 5 fellowship-trained foot and ankle surgeons at a single institution. A total of 51 patients met inclusion criteria with a mean follow-up of 31.2 months (SD = 16.2). Implant survival was 94%, There were 7 major complications (13%) requiring an unplanned return to the operating room and 8 minor complications (15%) that resolved with conservative care. The results of this study show that total ankle replacement is a viable treatment option for patients younger than 55 years. Levels of Evidence: A retrospective case series

Replacement Design

Recently, the progress in techniques and in projecting new prosthetic designs has allowed increasing indications for total ankle replacement (TAR) as treatment for ankle osteoarthritis. This retrospective work comprehended 39 subjects aged between 47 and 79 years old. The patients, observed for at least 12 months (mean follow up of 18.2 ± 4.1 months), have been evaluated according to clinical and radiological parameters, both pre- and post-operatively. The AOFAS and VAS score significantly improved, respectively, from 46.2 ± 4.8 to 93.9 ± 4.1 and from 7.1 ± 1.1 to 0.7 ± 0.5 (p value < 0.05). At the final evaluation, the mean plantarflexion passed from 12.2° ± 2.3° to 18.1° ± 2.4° (p value < 0.05) and dorsiflexion from a pre-operative mean value of 8.7° ± 4.1° to 21.7° ± 5.4° post-operatively (p value < 0.05). This study found that this new total ankle replacement design is a safe and effective procedure for patients effected by end-stage ankle osteoarthritis. Improvements have been demonstrated in terms of range of motion, radiographic parameters and patient-reported outcomes. However, further studies are needed to assess the long-term performance of these prostheses.

Category: Ankle, Ankle Arthritis Introduction/Purpose: In the last two decades, total ankle replacement (TAR) has gained more acceptance as a treatment option in patients with end-stage ankle osteoarthritis. However, there is a lack of literature on TAR using a lateral transfibular approach. Therefore, we sought to report early clinical and radiographic results of a patient cohort treated with TAR using a lateral transfibular approach by a single surgeon. Methods: Fifty-five primary total ankle arthroplasties using the Zimmer trabecular metal implant were performed in 54 patients (29 men and 25 women; mean age, 67.0 years) from October 2012 to December 2014. Clinical assessment including pain evaluation and measurement of ankle range of motion was done preoperatively and at the latest follow-up. Weight-bearing radiographs were used to determine the angular alignment of the tibial and talar components and to analyze the bone-implant interface. Intraoperative and postoperative complications, revision surgeries, and failures were evaluated. Results: Implant survival was 93% at 36 months follow-up. There were 3 revisions of a tibial component due to aseptic loosening. In 10 of 55 procedures, a secondary procedure was performed during follow-up. Mean follow-up duration was 26.6 ± 4.2 months. No delayed union or non-union was observed for fibula healing. The average VAS pain score decreased significantly from 7.9 ± 1.3 to 0.8 ± 1.2. The average total range of motion increased significantly from 22.9° ± 11.8° to 40.2° ± 11.8°. Conclusion: Early results of Zimmer trabecular metal total ankle replacement demonstrated improved patient-reported outcomes and increased ankle motion at a minimum follow-up of one year. In the first 55 consecutive cases, the fibular osteotomy required for access to the ankle healed without complications. Painful early loosening requiring revision due to lack of bony ingrowth was seen in 3 of 55 cases.

Category: Ankle Arthritis Introduction/Purpose: It has been shown that total ankle replacement (TAR) is effective in reducing pain and maintaining function in posttraumatic ankle osteoarthritis (OA). Compared to ankle fusion, TAR restores hindfoot kinematics more physiological. However, the assumption that the maintenance of ankle motion has a protective effect on the subtalar joint is still a matter of debate. Only a scarce number of long-term studies exist to support this statement.The purpose of this study was (1) to evaluate to which extent the integrity of the subtalar joint can be preserved by treating patients with a TAR, (2) to determine the rate of subtalar fusion following TAR, and (3) to determine whether the need of subsequent subtalar fusion was predictable at time of TAR. Methods: A consecutive series of 1140 primary TAR (508 female, 632 male, median age 63.5 years), performed between May 2000 and December 2015, were prospectively documented. The indication for TAR was posttraumatic OA in 78%, primary and systemic OA in 10% each, and other secondary OA in 3% of the cases. 199 subtalar joints were either fused before (n=73) or during TAR surgery (n=126), leaving 941 subtalar joints available for analysis. Radiographs before implantation and at latest follow-up were classified using the Kellgren and Lawrence Grading Score (KLS). In case of a subtalar fusion, the radiograph prior to the fusion was classified. Results: After a median radiographic follow-up of 6.1 years, the KLS remained unchanged in 66% of all cases. While it was increased by one stage in 30%, it was increased by two stages in 3%; whereas, signs of OA decreased by one stage in 1%. Cases with an increase of two stages on the KLS had a longer follow-up compared to cases without increase (p=0.047).37 cases (3.9%) underwent a subtalar joint fusion, of which the indication was progressive OA in 19 cases (51%), instability in 10 cases (27%) and others in 8 cases (22%). Subtalar joints that required a fusion after TAR did not show higher preoperative KLS than the group which did not need a subtalar joint fusion. Conclusion: Apparently, TAR protects the subtalar joint from secondary degeneration, as found in 67% with no increase in KLS. Although 33% showed an increase in the KLS, only 2% required a subtalar fusion due to progressive OA. Overall, the rate of subtalar joint fusion after TAR was low and comparable to the rates reported in the literature. Subtalar joints requiring fusion after TAR did not show higher preoperative rates of OA. Therefore, the KLS classification of subtalar OA on conventional radiographs provides only limited information about the need for postoperative subtalar fusion, and thus need to be interpreted with caution.

Category: Ankle Arthritis Introduction/Purpose: 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 longterm for MB-TAR and at intermediate-to-longterm follow-up for newer generation FB-TAR. Although comparisons between the two total ankle designs have been reported, to our knowledge, no investigation has compared the two 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: This investigation was approved by our institution’s IRB committee. 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, range 35 to 85) were enrolled; demographic comparison between the two 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 exam 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 (VAS), short form 36 (SF-36), foot and ankle disability index (FADI), short musculoskeletal functional assessment (SMFA) and AOFAS ankle-hindfoot score. Surgeries were performed by non-design team orthopaedic foot and ankle specialists with total ankle replacement expertise. Statistically analysis was performed by a qualified statistician. Results: 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, one had died, 4 were withdrawn after enrolling but prior to surgery and 4 were lost to follow-up. In all outcome measures, the entire cohort demonstrated statistically significant improvements from preoperative evaluation to most recent follow-up. There was no statistically significant difference in improvement in clinical outcomes between the two 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 FB-TAR, respectively. Re-operations were performed in 8 MB-TAR and 3 FB-TAR, with the majority of procedures being to relieve impingement or treat cysts and not to revise or remove metal implants. Conclusion: For the first time, with a high level of evidence, our study confirms that patient reported and clinical outcomes are favorable for both designs and that there is no significant difference in clinical improvement between the two implants. The incidence of lucency/cyst formation was similar for MB-TAR and FB-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 correlate with radiographic findings. Re-operations were more common for MB-TAR and in the majority of cases were to relieve impingement or treat cysts rather than revise or remove metal implants.

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.

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; Ankle Arthritis Introduction/Purpose: Total ankle arthroplasty (TAA) is increasingly used for treatment of end stage arthritis of the ankle; improvements continue to evolve in implant design and instrumentation. We present our experience of the Infinity Total Ankle Arthroplasty (Wright Medical), a fixed bearing 4th generation implant with improved instrumentation Methods: This is a retrospective review of prospectively collected data. From October 2016 to July 2019, we identified 92 (52M/40F) who had the infinity Total Ankle Replacement. This review is of 70 patients with a minimum of 1 year follow up (33M,37F). The mean age was 67.5 years (33-87); 32 right side and 38 left no bilaterals. The indication for surgery was end stage Osteoarthritis in 52, post traumatic arthritis 12, inflammatory arthritis 4, conversion of fusion to TAR 2. The preoperative deformity was graded according to the COFAS classification. All patients had follow up at 6 weeks, 3,6 and 12 months and then annually, with MOXFQ questionnaire and weight bearing radiographs. Results: TAA was performed with the use of fluoroscopy. 77% (54/70) had concomitant procedures as listed in Table.5% (4/70) had complications consisting of, 1 DVT, 1 intra operative medial malleolus fracture, 1 EHL tendon laceration and 1 wound break down. There were no deep or superficial infections. Improvement in clinical outcome and PROMS data was noted on follow up. The MOXFQ for Pain improved from 72 pre-op to 25 at 1year (p<0.001). The outcome for Walking improved from 83 pre-op to 30 at one year (p<0.001). Radiological alignment was maintained asymptomatic posterior heterotopic ossification was noted in 23(16%) patients, lucent lines under the tibial implant were noted in 4 ankles and 1 fibula erosion. 2 TAA (3%) needed to be revised due to malpositioning. Conclusion: Our results show significant improvement in patient outcomes, a short recovery time and marked improvement in mobility post operatively with a very low complication rate, we had no deep infection to date. Two implants were revised which we attribute to the learning curve at the start of practice. This implant is fluoroscopically navigated allowing precise implantation with dedicated instrumentation and we feel this attributed to the low complication rate and good results in our short-term study [Table: see text]

Category: Ankle, Ankle Arthritis, Sports Introduction/Purpose: Total ankle replacement (TAR) and ankle arthrodesis (AA) are two common surgical treatment modalities for end stage tibiotalar arthritis. A key deciding point between the two is anticipated functional outcome postoperatively, especially in regards to sports related activities. However, there is a paucity of data available to help advise patients in their decision making. While TAR provides a theoretical benefit of improved functionality, the outcomes of several European studies have shown mixed results. These studies are limited by small sample size, obsolete TAR implants not used in the United States, and nonspecific outcome measures. The purpose of this study was to compare postoperative sports activity levels following modern TAR and AA in a U.S. population, which may benefit surgical decision making and guide patient expectations. Methods: We conducted a retrospective comparative study that consisted of patients who underwent a TAR (N=62) or AA (N=51) between 2009-2015. The mean age of the arthrodesis group was 57.7 years ± 12.12 (28.84-85.26). There were 27 male participants and 24 female participants. The TAR group had 31 male and 31 female participants with a mean age of 64.9 years ± 8.57 (45-79.6). Exclusion criteria included paralysis, rheumatoid arthritis, revision surgery, incomplete pre- and post-operative scores, and follow up less than 2 years. General health and foot-ankle function were assessed using the SF-12 Health Survey and the revised Foot Function Index (FFI-R) preoperatively and at final follow-up. In addition, activity levels were assessed using a Return to Activities Following Surgery questionnaire that was administered at final follow up. This form included a Visual Analog Scale for Pain, satisfaction questions, and a list of 25 activities. Patients were asked to record their current level of activity, ability to participate pre- and post-surgery, and whether their desired level was met. All three measurements tools were compared between both treatment groups. Results: The SF-12 physical score both groups significantly increased postoperatively from 33.18 ± 10.37 to 43 ± 10.32 for AA’s and from 32.88 ± 9.44 to 45.81 ± 12.94 (p < 0.001) for TAR’s. The FFI scores showed a significant increase in both groups (p < 0.001). In the AA group, 88% of patients returned to work and would repeat the surgery, compared to 92% of patients in the TAR group. In terms of satisfaction and pain, the TAR group was more satisfied (1.78 vs. 1.44) and had less postoperative pain (1.32 vs. 2.56 p < 0.05). The AA group reported a significant increase in six activities including: golf (p < 0.05), weight lifting, and walking (p<0.001), while the TAR group reported significant increase in 15 activities, including hiking, tennis, and yoga (p<0.001). Conclusion: Our study revealed a significant increase in general physical function, foot function, and activity level in both groups. The TAR group was able to perform a wider range of activity and sports compared to the AA group. Overall, TAR patients were significantly more satisfied with their procedure compared to AA patients.
