In end-stage ankle arthritis, little is known about the impact of concomitant knee pathology, including the impact of ipsilateral knee pain on total ankle arthroplasty (TAA) outcomes. The aim of this study was to determine the prevalence of ipsilateral preoperative knee pain in patients undergoing TAA and analyze its impact on patient-reported functional outcome measures (PROMs). A retrospective review was performed on the Vancouver End Stage Ankle Arthritis Database at a single institution. In total, 114 patients were studied, with patient demographics collected preoperatively, including the presence or absence of knee pain. Postoperative follow-up was performed at 5 years, primarily analyzing disease-specific PROMs, including the Ankle Osteoarthritis Score (AOS) and Ankle Arthritis Score (AAS). Multivariate mixed-effects linear regression models compared the scores between the groups. In total, 31 patients (27.2%) presented with concomitant ipsilateral knee pain. Despite more females in the knee pain group (64.5% vs 36.1%) there were no other significant differences at baseline between the knee pain and no knee pain groups in terms of demographics or baseline primary disease specific PROMs. At 5 years, the patients with knee pain had significantly worse AAS (37.9 ± 23.8 vs 21.2 ± 16.3, P = .004) and AOS total scores (38.1 ± 24.1 vs 21.9 ± 15.5, P = .005) compared with the no-knee pain group. Both groups improved significantly from baseline across all outcome measures; however, the magnitude of improvement was less in the knee pain group. Our study demonstrated that over one-quarter of patients with end-stage ankle arthritis undergoing TAA present with ipsilateral concomitant knee pain. If present, it is associated with worse functional outcomes at the 5-year mark. Further studies are needed to evaluate if knee pain influences complications, implant failure rates, and survival.

Category: Ankle Arthritis Introduction/Purpose: Ankle arthritis can be a debilitating disease that results in decreased daily activity and chronic morbidity. Many patients elect for surgical intervention to minimize pain and improve function. To curb costs associated with the increasing demand for total joint arthroplasty (TJA) in the growing elderly Medicare population, CMS announced the Comprehensive Care for Joint Replacement (CJR) model, which included total ankle arthroplasty. To provide continued quality care and cost containment, it is necessary to determine the optimal surgical intervention for patients that could fall within the CJR program. Therefore, we sought to determine the impact of surgical fixation on functional outcomes, systemic utilization, and medical expenditures for patients with ankle arthritis. Methods: We reviewed a prospectively collected and maintained database to identify all patients who underwent a total joint replacement from April 2016 to September 2017. Patients were identified based on DRG codes for primary arthritis of a lower extremity joint, then specifically for foot and ankle, as well as CPT codes for ankle arthroplasty (27702) or ankle arthrodesis (27870/28725). Functional outcomes were assessed based on insurance type. The cohorts were matched for age, comorbidities, and gender. Statistical analysis was performed using chi-squared and paired t-test to assess for differences in patient reported outcomes. Descriptive statistical analysis was used to assess for differences in cost between the cohorts. Results: A total of 573 patients were included.There were 48 replacements and 47 fusions. Arthrodesis procedures costs approximately $6,500 less per case than the system costs for patients who underwent arthroplasty procedures. The average length of stay for patients who underwent total ankle arthroplasty was 1.6 days compared to outpatient surgical centers utilized for most arthrodesis patients. Overall, patients reported improved pain and a 30.96 increase in FAAM scores. Most patients had a global rate of change that was “very much better” or “much better” (68%). Based on insurance type, patients who underwent a total ankle replacement in the CJR program had improved outcomes and lower cost than patients commercially insured. Conclusion: With the CJR, there is greater emphasis on the optimal intervention for elective operations. There should be coordinated efforts to optimize quality care, while minimizing financial waste within the healthcare system. The price differential suggests an annual potential for financial savings as high as $325,000 for a system that supports intervention for ~50 cases per year. As such, these results suggest that arthroplasty may be optimal for patients with severe symptomatic ankle arthritis, while most patients have adequate relief with an ankle fusion. More importantly, quality improvement efforts should focus on the impact of surgical intervention on functional activity.

The Impact

Category: Ankle Arthritis Introduction/Purpose: Accepted surgical treatment options for end-stage ankle arthritis include total ankle arthroplasty (TAA) and ankle arthrodesis (AA). Although they have comparable clinical outcomes, TAA is growing in popularity and one reason for this is that TAA, compared to AA, better preserves range of motion and function at the ankle, and results in a gait pattern that more closely replicates normal controls. This has the theoretical benefit of protecting adjacent articulations and thereby limiting degenerative changes from occurring in other joints. Although multiple studies have analysed the impact of both TAA and AA on adjacent joint disease in the foot, little data exists on their impact on the knee. This study explored the relationships between knee pain, TAA and AA in patients with end-stage ankle arthritis. Methods: Prospectively collected data was used from the Canadian Orthopaedic Foot and Ankle Society (COFAS) database of ankle arthritis at a single institution by three fellowship-trained foot and ankle surgeons between January 2003 and July 2012. In total, 342 patients were studied, with patient demographics collected pre-operatively, and post-operative follow up performed at the 5 year mark. All patients were examined for the development or resolution of knee pain, as well as patient-reported outcome measures including the Ankle Osteoarthritis Scale (AOS). Using a linear regression model, a multivariate analysis was performed to examine the relationship between knee pain, TAAs and AAs. Results: In the 233 patients that presented without knee pain pre-operatively, 22% who underwent TAA developed knee pain at 5 years, compared to 16% of AA patients (p>0.05). In this group, patients who underwent TAA had statistically significant better outcomes in terms of AOS Pain (p<0.02), AOS Difficulty (p<0.05) and AOS Total Scores (p<0.02). In the 109 patients who presented with knee pain, knee pain resolved in 47% of TAA patients vs 38% of AA patients at 5 years (p<0.05). There was no statistically significant difference in AOS outcomes (p>0.05) between patients who underwent TAA and AA. Compared with patients who did not have knee pain pre-operatively, the presence of pre-operative knee pain resulted in worse AOS (p<0.02), with no difference between TAA and AA. Conclusion: In those patients presenting without knee pain, TAA did result in more superior functional outcomes, with no significant difference in development of knee pain compared to AA. In patients with pre-operative knee pain, TAA had benefits of improved resolution of knee pain, with no difference in functional outcomes when compared with AA. Regardless of surgical technique, the presence of pre-operative knee pain was an independent adverse predictor of outcome in patients with tibiotalar arthritis.

Category: Ankle Arthritis Introduction/Purpose: Total ankle arthroplasty (TAA) is gaining popularity as an alternative to ankle arthrodesis in the setting of end-stage ankle arthritis. However, compared to hip and knee arthroplasty, there is a relative dearth of evidence to support its use. This study assesses the quality of literature surrounding modern TAA designs. Methods: A search of all peer-reviewed, English-language journals was conducted to identify publications involving TAA. The initial search identified 444 articles published during 2006-2016. Of these, 182 were excluded because they were not clinical outcomes studies, 46 because the TAA implant was no longer available, and 15 because the primary outcome of the study was not related to TAA, leaving 201 articles for analysis. Results: No Level I studies were identified. Seventeen (8%) studies were Level II, 48 (24%) Level III, 128 (64%) Level IV, and 8 (4%) Level V. One hundred forty-three studies (71%) were retrospective in nature. Stratification by study design revealed 128 (64%) case series, 33 (16%) experimental cohort studies, 19 (10%) case-control studies, 13 (6%) observational cohort studies, and 8 (4%) case reports. The number of studies published each year steadily increased from 2006 to 2016. A total of 51% of TAA research was published in only two journals: Foot and Ankle International and the Journal of Bone and Joint Surgery. Publications from the United States accounted for 36% of total publications. The most published implant was the Scandinavian Total Ankle Replacement (Figure 1). Conclusion: While the number of TAA studies published each year has steadily increased since 2006, the quality of this research as measured by level of evidence remains suboptimal. This analysis highlights the need for continued improvement in methodology and development of robust prospective registries to advance our knowledge of TAA as a treatment for end-stage ankle arthritis.

Background: Total ankle arthroplasty is a viable option for the treatment of end stage ankle arthritis. The purpose of this study is to report on the mid-term results with a cemented total ankle prosthesis, the Inbone™ II implant over a 5 year period. Methods: A retrospective, single-center chart and radiographic review of all patients with end stage ankle arthritis treated with Inbone™ II TAR) as the primary index procedure from 12/1/2012 to 3/1/2017. Clinical data were evaluated at 3 month, 6 month, 1 year and subsequent intervals for the study period. Preoperative diagnosis, pertinent patient demographics adjunctive procedures, implant associated complications, subsequent surgeries, and revisions were recorded. Results: 121 total ankles met our inclusion criteria. Patients had an INBONE™ II TAR implant placed with bone cement with a minimum of a 12 months follow up. Average age was 62.88 (range, 32-87) years, average body mass index was 32.74 (range, 21.8-56.04) kg/m2 and average follow up was 28.51(range, 12-69) months. Using the COFAS complication classification there were 14 minor, 11 moderate, and 5 major complications. 6/121 (5.0%) revisions which included: polyethylene exchange, device explant/fusion, and antibiotic spacer in situ. No complications over the course of this study ended in amputation. Conclusion: Total Ankle Arthroplasty utilizing the cemented INBONE™ II yielded good midterm results with regards to minor, moderate, and major complications. Rate of revision 6/121 (5.0%) was within the reported range with only 5 patients converted to fusion during the study period resulting in a 95% survivability at mid-term follow up.

Category: Ankle Arthritis Introduction/Purpose: Ankle push off power, which requires gastroc-soleus muscle strength, is a critical aspect of healthy gait and increases as gait speed increases. It is therefore surprising that one-to-two-year outcomes following total ankle arthroplasty (TAA) include improved gait speed but deficient ankle power. One possible explanation for low ankle power following TAA is ankle plantarflexion weakness. Information on plantarflexion strength is extremely limited in people before or after TAA. Evaluating plantarflexion strength may inform postoperative expectations and guide rehabilitation programs. The purpose of this study was to evaluate the change in ankle plantarflexion strength, ankle power during gait, and gait speed before and after TAA in people with end-stage ankle arthritis, and in comparison to a healthy matched control group. Methods: Twenty-five participants were included in this prospective case-control study. TAA group participants (n = 13) [mean (SD): Age 60.9 (15.3) years; BMI 30.53 (5.5) Kg/m2; 85% male] with end-stage ankle arthritis who received a TAA were evaluated preoperatively and six months postoperatively. Performance of adjunct soft tissue procedures were patient specific (5/13 participants received tendo-achilles lengthening). All patients received formal physical therapy. Healthy control participants (n=12) were matched to the TAA group on age, gender and BMI. Ankle peak isokinetic plantarflexion strength (torque at 60 and 120 degrees/second; Nm/kg) was measured with an instrumented dynamometer. Peak ankle power (joint torque x segmental velocity; W/kg) was calculated via three-dimensional multi-segment foot motion analysis while participants walked barefoot over a force plate at controlled speeds. Gait speed (m/s) was measured with the Six-Minute Walk Test. Appropriate nonparametric comparisons were made to evaluate differences across time, between limbs, and between groups. Results: Compared to preoperative values, involved limb ankle strength was preserved at 60 and 120 degrees/second following TAA (both p > 0.59). Postoperative involved limb ankle strength at both speeds were 37-56% lower than the non-involved limb and control group (all p < 0.05) (Figure 1). Similarly, involved limb ankle power was preserved following TAA (p = 0.43), but remained at least 38% lower than the non-involved limb or control group (both p < .01). A subset analysis revealed that TAA participants with tendo-achilles lengthening had 25-33% less involved limb postoperative ankle power and strength than TAA participants without tendo-achilles lengthening. Interestingly, gait speed increased following TAA (p = 0.01) and was similar to control group speeds [TAA 1.5 vs. Control 1.6 m/s; p = 0.59]. Conclusion: Robust improvements in gait speed were observed following TAA. These values approached normative gait speed in spite of diminished ankle strength and power. Ankle plantarflexion weakness reduces the capacity to generate ankle power during gait, regardless of possible contributing factors (i.e. preexisting atrophy/weakness, tendo-achilles lengthening). Accordingly, improvements in gait speed were likely linked to proximal joint compensations (i.e. hip, knee). The long term consequences of plantarflexion weakness may negatively affect implant loading. Study findings provide new information and point to the importance of targeting strength during postoperative TAA rehabilitation, potentially adjusting strategies for patients receiving soft tissue lengthening procedures.
