Two for One: Bilateral Simultaneous versus Staged Total Ankle Arthroplasty, are Patient-Centered Outcomes Equivalent?

Category: Ankle; Ankle Arthritis Introduction/Purpose: The utilization of total ankle arthroplasty has increased over the past decade, including bilateral TARs. The risk-benefit profiles of staged versus simultaneous joint arthroplasty continues to be debated in the literature. Previous studies of the hip and knee have demonstrated simultaneous bilateral surgery is associated with shorter hospitalization, shorter recovery and rehabilitation time, and decreased cost without increasing perioperative morbidity or mortality. There are limited case series reporting outcomes after bilateral TAR with no previous comparison of simultaneous versus staged TAR. Thus, we aim to compare our experience with bilateral simultaneous versus staged TARs including perioperative complications and patient reported outcomes. Methods: We performed a retrospective study on 62 patients (124 ankles) undergoing primary TAA (CPT 27702) from 2008 at a single academic center. Inclusion criteria were primary bilateral TAA performed in staged or simultaneous fashion in patients over the age of 18 years-old. Exclusion criteria were patients with less than one-year follow-up. Patient demographics, comorbidities, concomitant procedures, perioperative complications, and patient reported outcomes were also collected. Patient reported outcomes included preoperative and postoperative visual analog scale (VAS) for pain, the Short Form-36 (SF-36) Health Survey, the American Orthopaedic Foot & Ankle Society (AOFAS) score, the Foot and Ankle disability Index (FADI) score, and the Short Musculoskeletal Function Assessment (SMFA) bother and function sub-scores. Every patient had separate outcome scores available for each ankle. Univariate and multivariable tests of significance were used to relate patient and operative characteristics to outcomes. Separate subgroup analyses were performed comparing stages versus simultaneous surgeries. Results: The mean age was 63.7 years-old with a mean duration of 40.5 months of clinical follow-up. There were no significant pre-operative differences between simultaneous and staged groups in terms of age, gender, BMI, ASA classification, or arthritis etiology (p>0.05). The majority (54.5%) of patients had primary or secondary arthritis. Comorbidities were similar between the two groups with the exception of the simultaneous cohort having a higher proportion of previous smokers (56.3 vs 26.1, p=0.0020) and coronary artery disease (19.8 vs 6.5, 0.0447). There was no difference in perioperative complications between the groups(p= 0.4652). Both cohorts significantly improved in all reported patient reported outcomes at final follow-up (<0.001) without a difference in overall improvement between groups (p >0.05) (Table 1). Conclusion: The prevalence of osteoarthritis (primary arthritis) and inflammatory arthritis (secondary arthritis) was higher in patients with bilateral end-stage arthritis necessitating a TAR than previous reports of unilateral TAR. The results of bilateral simultaneous TAA, including perioperative complications and patient reported outcomes, are comparable to patients undergoing staged TAA. We advocate that simultaneous bilateral TAA is a safe and effective method the treatment of bilateral end-stage ankle osteoarthritis in a setting where experienced surgeons are available. Potential benefits of simultaneous TAR for further investigation include decreased: anesthesia events, surgery time, length of hospitalization, recovery and rehabilitation time, and overall cost.

Background: 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 proven 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 follow-up of at least 2 years. Methods: This prospective study included 89 patients who underwent transfibular total ankle arthroplasty from May 2013 to February 2016. The mean age was 53.2 ± 13.5 years. All patients were followed for at least 24 months postoperatively with an average follow-up of 42.0 ± 23.5 months. Patients were assessed clinically and radiographically preoperatively and at 6, 12, and 24 months postoperatively. Results: At 24 months postoperatively, patients demonstrated statistically significant improvement in the American Orthopaedic Foot & Ankle Society (AOFAS) Ankle Hindfoot Score from 33.8 ± 14.3 to 88.5 ± 6.6 ( P < .001), visual analog scale (VAS) from 80.5 ± 17.0 to 14.1 ± 9.2 ( P < .001), and Short Form-12 Physical and Mental Composite Scores from 29.9 ± 6.7 and 43.3 ± 8.6 to 47.0 ± 7.6 and 53.3 ± 8.1, respectively ( P < .001). In addition, ankle dorsiflexion and plantarflexion improved from 6.2 ± 5.5 and 9.6 ± 5.8 degrees to 24.2 ± 7.9 and 18.1 ± 7.6 degrees, respectively ( P < .001). Radiographically, patients demonstrated maintained neutral alignment of the ankle at 24 months. No patient demonstrated any radiographic evidence of tibial or talar lucency at final follow-up. Seven patients underwent reoperation for removal of symptomatic hardware (6 fibular plates, 1 syndesmotic screw); 2 patients experienced delayed wound healing. The first one was treated with plate removal and flap coverage. The second one required fibular plate removal. One patient developed a postoperative prosthetic infection requiring operative debridement, removal of implants, and placement of an antibiotic spacer. Conclusion: This study found that transfibular total ankle replacement was a safe and effective option for patients with ankle arthritis resulting in improvements in patient-reported outcomes, range of motion, and radiographic parameters. However, further studies are required to determine the mid- and long-term performance of these implants. Level of Evidence: Level IV, case series.

Background: The Salto Talaris is a fixed-bearing implant first approved in the US in 2006. While early surgical outcomes have been promising, mid- to long-term survivorship data are limited. The aim of this study was to present the survivorship and causes of failure of the Salto Talaris implant, with functional and radiographic outcomes. Methods: Eighty-seven prospectively followed patients who underwent total ankle arthroplasty with the Salto Talaris between 2007 and 2015 at our institution were retrospectively identified. Of these, 82 patients (85 ankles) had a minimum follow-up of 5 (mean, 7.1; range, 5-12) years. The mean age was 63.5 (range, 42-82) years and the mean body mass index was 28.1 (range, 17.9-41.2) kg/m2. Survivorship was determined by incidence of revision, defined as removal/exchange of a metal component. Preoperative, immediate, and minimum 5-year postoperative AP and lateral weightbearing radiographs were reviewed; tibiotalar alignment (TTA) and the medial distal tibial angle (MDTA) were measured to assess coronal talar and tibial alignment, respectively. The sagittal tibial angle (STA) was measured; the talar inclination angle (TIA) was measured to evaluate for radiographic subsidence of the implant, defined as a change in TIA of 5 degrees or more from the immediately to the latest postoperative lateral radiograph. The locations of periprosthetic cysts were documented. Preoperative and minimum 5-year postoperative Foot and Ankle Outcome Score (FAOS) subscales were compared. Results: Survivorship was 97.6% with 2 revisions. One patient underwent tibial and talar component revision for varus malalignment of the ankle; another underwent talar component revision for aseptic loosening and subsidence. The rate of other reoperations was 21.2% ( n = 18), with the main reoperation being exostectomy with debridement for ankle impingement ( n = 12). At final follow-up, the average TTA improved 4.4 (± 3.8) degrees, the average MDTA improved 3.4 (± 2.6) degrees, and the average STA improved 5.3 (± 4.5) degrees. Periprosthetic cysts were observed in 18 patients, and there was no radiographic subsidence. All FAOS subscales demonstrated significant improvement at final follow-up. Conclusions: We found the Salto Talaris implant to be durable, consistent with previous studies of shorter follow-up lengths. We observed significant improvement in radiographic alignment as well as patient-reported clinical outcomes at a minimum 5-year follow-up. Level of Evidence: Level IV, retrospective case series.

Background: Ankle ligamentous injuries without fracture can result in end-stage ligamentous post-traumatic osteoarthritis, which may cause ligamentous imbalance after total ankle arthroplasty (TAA). However, outcomes of TAA in these patients are not well known. The purpose of this study was to evaluate intermediate-term clinical and radiographic outcomes of TAA in patients with ligamentous post-traumatic osteoarthritis and compare them with results of TAA for patients with primary osteoarthritis. Methods: We enrolled 114 patients (119 ankles) with consecutive primary TAA using HINTEGRA prosthesis at a mean follow-up duration of 6.0 years (range, 3-13). We divided all patients into 2 groups according to the etiology of osteoarthritis: (1) primary osteoarthritis group (69 ankles) and (2) ligamentous post-traumatic osteoarthritis group (50 ankles). Results: There was no significant intergroup difference in mean Ankle Osteoarthritis Scale (AOS), American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score, Short Form-36 Physical Component Summary, visual analog scale pain score, ankle range of motion, or complications at the final follow-up. However, the final tibiotalar angle was less corrected to 4.2 degrees in the ligamentous post-traumatic osteoarthritis group compared to 2.7 degrees in the primary osteoarthritis group ( P = .001). More concomitant procedures were required at the index surgery for the ligamentous post-traumatic osteoarthritis group ( P = .001). The estimated 5-year survivorship was 93.4% (primary osteoarthritis group: 91.3%; ligamentous post-traumatic osteoarthritis group: 95.8%). Conclusions: Clinical outcomes, complication rate, and 5-year survivorship of TAA in ankles with primary and ligamentous post-traumatic osteoarthritis were comparable with intermediate-term follow-up. Our results suggest that TAA would be a reliable treatment in ankles with ligamentous post-traumatic osteoarthritis when neutrally aligned stable ankles are achieved postoperatively.

Category: Ankle Arthritis Introduction/Purpose: The Scandinavian Total Ankle Replacement(STAR) system and Salto Talaris(ST) total ankle system are two of the more commonly studied total ankle implants. As the STAR is one of the oldest total ankle arthroplasty (TAA) implants still in use today, most studies focus on longevity and survivorship. Reported rates of cyst formation for these two prosthesis in most series vary from 11-22% but no large study has focused on surgical management of these cysts or included patient reported outcomes after surgery. In this series, we aimed to investigate rates of cyst formation between mobile(MB) and fixed-bearing(FB) TAA and examine clinical and patient reported outcomes of bone grafting or cementing of large cysts surrounding the STAR and ST implants. Methods: A prospectively collected database at a high volume total ankle replacement center was retrospectively reviewed to identify patients who underwent TAA with either the STAR or the ST total ankle system between 2007 and 2015. Cysts were identified and measured on standard weight bearing radiographs and confirmed on computed tomography(CT) when available. Visual analog scale (VAS) score, Short Form-36 (SF-36) physical and mental component scores, Short Musculoskeletal Function Assessment(SMFA), and AOFAS hindfoot scores were collected from all patients preoperatively and then at 6 months, 1 year and annually postoperatively. Patients with a minimum 2 years follow-up who underwent revision TAA secondary to catastrophic bone cysts or who were managed with either curettage and bone grafting or curettage and cementing of bone cysts surrounding the TAA prosthesis were included in the patient reported outcomes (PRO) analysis Results: Excluding 53 patients for inadequate follow-up, 232 patients (29% female, 71% male; follow-up 6.7 years) who underwent STAR-TAA and 147 patients (26.6% female, 73.5% male; follow-up 7 years) who underwent ST-TAA were identified. Cysts <20 mm diameter occurred more often in the MB TAAs, and more often in the tibia than talus (table). Cysts >10 mm were identified in 95/232 (41%) STAR and 24/147 (16%) ST ankles. In the STAR group, 24 patients underwent cyst bone grafting (13), cementing (6) or both (8) at a mean 4.8 years. In the ST group, 14 patients underwent cyst bone grafting (6), cementing (4), or both (4) at a mean of 2.7 years. PRO data improved significantly for both the STAR and ST group in all questionnaires (p<0.05 for all). Conclusion: Mobile-bearing total ankle arthroplasty in this cohort had a higher rate of cyst formation greater than 10 mm (95/232 patients, 41%) when compared to a fixed-bearing TAA (24/147, 16.3%). Only 24/95 (25%) of STAR patients and 14/24 (58%) of ST patients required surgical intervention for cyst management. Patient reported outcomes after cyst surgery improved significantly when compared to pre-cyst management surgery and did not differ between MB and FB cohorts (p=0.424). Successful surgical management of large cyst surrounding either mobile-bearing or fixed-bearing total ankle systems can be expected based on the results of this study. [Table: see text]

Background: Ankle disorders in patients with rheumatoid arthritis (RA) reduce their quality of life and activities of daily living. The aim of this study was to evaluate the midterm clinical and radiographic outcomes of TAA in patients with RA. Methods: This retrospective study included patients with a minimum follow-up of 2 years. A total of 37 RA patients (39 ankles) were enrolled in this study from August 2006 to March 2016. All the patients had undergone primary cemented mobile-bearing total ankle arthroplasty (TAA). Nine ankles received arthrodesis of the subtalar joint simultaneously. Patient-reported outcomes were measured preoperatively and at the latest follow-up by Self-Administered Foot-Evaluation Questionnaire (SAFE-Q). Radiographs of the ankle were analyzed preoperatively and at all follow-up visits to measure the periprosthetic radiolucent line, migration of the tibial component, and the subsidence of the talar component. Intraoperative and postoperative complications were recorded. The average duration of follow-up for the entire cohort was 5.0 ± 2.0 years (range 2.1-10.1 years). Results: All subscales of the SAFE-Q had improved significantly at the latest follow-up. No significant difference was found between the range of motion of the ankle before and after the surgery. Radiolucent lines were observed in 28 (73.7%) ankles. Migration of the tibial component and subsidence of the talar component were found in 8 (21.1%) and 11 (28.9%) ankles, respectively. Intraoperative malleolus fractures occurred in 3 (7.7%) ankles and delayed wound healing in 10 (25.6%) ankles. Four ankles were removed because of deep infection or noninfective loosening, resulting in an implant survival rate of 88.4% (95% CI, 0.76-1.0) at 10 years. Conclusion: The midterm patient-reported outcomes and implant retention rate after cemented mobile-bearing TAA for RA patients were satisfactory. However, a low radiographic implant success rate was observed. Level of Evidence: Level IV, retrospective case series.

Introduction. Failure to correct coronal deformity at the time of total ankle arthroplasty (TAA) can lead to early implant failure. We aimed to determine clinical, radiographic, and patient-reported outcomes of patients with moderate to severe valgus deformity who underwent TAA for end-stage ankle arthritis. Methods. Patients with a valgus deformity of at least 10° who underwent TAA were retrospectively reviewed. The coronal tibiotalar angle was assessed on radiographs preoperatively, at 1 year, and at final follow-up. The visual analog scale (VAS) for pain, Short Form-36 (SF-36), American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot-ankle scale, and Short Musculoskeletal Function Assessment (SMFA) scores were assessed preoperatively and at final follow-up. Results. Mean preoperative valgus deformity was 15.5 ± 5.0°, and was corrected to a mean of 1.2 ± 2.6° of valgus postoperatively. VAS, SF-36, AOFAS, and SMFA scores improved significantly ( P < .001 for all). There was no significant change in tibiotalar angle between 1 year and final follow-up in either group. Reoperation and revision rates did not differ between groups. Conclusion. Correction of coronal alignment was achieved and maintained in patients with both moderate and severe preoperative valgus malalignment. Outcome scores significantly improved for all patients.

Background: Total ankle arthroplasty (TAA) has been developed to treat patients with end-stage ankle osteoarthritis (OA). However, there is often difficulty in treating complicated pathologies such as ankle OA with subtalar joint OA and severe talar collapse. Therefore, this study aimed to explore the short-term results and complications of TAA with total talar prosthesis, known as combined TAA, as the new techniques to treat such complicated pathology. Methods: We examined postoperative results including ankle range of motion, Japanese Society for Surgery of the Foot (JSSF) scale, and complications. There were 22 patients (15 women), with mean follow-up of 34.9 (range, 24–53 months), and the mean age was 72 (range, 62–80) years. The main indications for combined TAA included osteoarthritis (18 patients), rheumatoid arthritis (3 patients), and talar osteonecrosis with osteoarthritis (one patient). Results: The mean range of motion improved from 4.0 to 14.4 degrees in dorsiflexion and from 23.8 to 32.0 degrees in plantarflexion. The JSSF scale improved from 50.5 to 91.5 points. Prolonged wound healing occurred in 3 patients, and medial malleolus fracture occurred in 4 patients. Conclusion: Combined TAA was a reliable procedure for the treatment of not only ankle OA following avascular necrosis of talus but also of degeneration of both ankle and subtalar joints. Level of Evidence: Level IV, case series.

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.

The Impact

Category: Ankle Introduction/Purpose: Poor pre-operative mental health and depression have been shown to negatively impact patient- reported outcomes (PROMs) after a broad array of orthopaedic procedures involving the spine, hip, knee, shoulder, and hand. However, the relationship of mental health and patient-reported outcomes in foot and ankle surgery is less clear. The purpose of this study is to characterize the impact of pre-operative mental health and depression on patient-reported outcomes after total ankle arthroplasty. The study hypothesis is that depression and decreased SF36 MCS will be significantly associated with diminished improvement in PROMs after total ankle arthroplasty. Methods: All patients undergoing primary TAA between January 2007 and December 2016 who were enrolled into a prospective, observational study and who had at least 1 to 2-year minimum study follow-up were included. Patients were separated into 4 groups based on the presence or absence of SF36 MCS<35 and diagnosis of depression. Pre-operative to post- operative change scores in the SF36 physical and mental component summary scores (PCS and MCS), Short Musculoskeletal Function Assessment (SMFA) function and bother components, and visual analog scale (VAS) pain were calculated in 1 to 2-year follow-up. Multivariable, main effects linear regression models were constructed to evaluate the impact of SF36 and depression status on pre-operative to 1 to 2-year follow-up change scores with adjustment for age, sex, race, body mass index, current smoking, American Society of Anesthesiologist’s score, smoking, and Charlson-Deyo comorbidity score. Results: As in Table 1, adjusted analyses demonstrated that patients with MCS<35 and depression had significantly lower improvements in all change scores including SF36 MCS (-5.1 points) and PCS (-7.6 points), SMFA bother (6 points) and function scores (5.7 points), and VAS pain (7.5 points) compared with patients that had SF36>=35 and no depression. Patients with MCS<35 and no depression had significantly greater improvement in SF36 MCS (5.3 points) compared with patients that had MCS>=35 and no depression. Patients with MCS>=35 and depression had significantly lower improvement in SF36 MCS (-3.2 points) compared with patients that had MCS>=35 and no depression. Adjusted analyses of minimum 5-year outcomes demonstrated significantly increased improvement in MCS and SMFA function for patients with pre-operative MCS<35 and no depression. Conclusion: Presence of depression and decreased SF36 MCS are risk factors for diminished improvement in PROMs. Patients with depression and decreased MCS should be counseled about their risk of diminished improvement in outcomes compared to peers. As PROM’s become part of physician evaluations, it is becoming increasingly important to identify factors for diminished improvement outside of the physician’s control. [Table: see text]

Background: Total ankle arthroplasty (TAA) is commonly pursued for patients with painful arthritis. Outpatient TAA are increasingly common and have been shown to decrease costs compared to inpatient surgery. However, there are very few studies examining the safety of outpatient TAA. In this study, we retrospectively reviewed 65 consecutive patients who received outpatient TAA to identify complication rates. Methods: The medical records of 65 consecutive outpatient TAA from October 2012 to May 2016 with a minimum 6-month follow-up were reviewed. All patients received popliteal and saphenous blocks prior to surgery and were managed with oral pain medication postoperatively. All received a STAR total ankle. Demographics, comorbidities, American Society of Anesthesiologists (ASA) class, and perioperative complications including wound breakdown, infection, revision, and nonrevision surgeries were observed. Mean follow-up was 16.6 ± 9.1 months (range, 6-42 months). Results: There were no readmissions for pain control and 1 patient had a wound infection. The overall complication rate was 15.4%. One ankle (1.5%) had a wound breakdown requiring debridement and flap coverage. This patient thrombosed a popliteal artery stent 1 month postop. The 1 ankle (1.5%) with a wound infection occurred in a patient with diabetes, obesity, hypertension, and rheumatoid arthritis. Conclusion: This study demonstrates the safety of outpatient TAA. The combination of regional anesthesia and oral narcotics provided a satisfactory experience with no readmissions for pain control and 1 wound infection. The 1 wound breakdown complication (1.5%) was attributed to arterial occlusion and not outpatient management. Level of Evidence: Level IV, retrospective case series.
