Category: Ankle Introduction/Purpose: Acute hematogenous periprosthetic joint infection(PJI) is defined in the literature as infection diagnosed and treated within two to four weeks from the onset of symptoms. In total hip and knee arthroplasty, irrigation, debridement(I&D) and polyethylene exchange with component retention is the treatment of choice. There is minimal literature evaluating this treatment method for PJI in total ankle arthroplasty (TAA), however, with four patients being the largest sample size. The purpose of this study was to evaluate both the clinical and patient reported outcomes and survivorship of treating PJI in TAA with I&D and polyethylene exchange in patients with acute hematogenous PJIs. Methods: A single center, retrospective chart review of prospectively collected data in patients with TAA PJI who subsequently underwent I&D and polyethylene exchange with retention of metal components was conducted. The primary outcome was failure rate of I&D and polyethylene exchange where failure was defined as subsequent removal of all components and two-stage revision or arthrodesis. Patient reported outcomes collected before primary arthroplasty, after primary arthroplasty and after polyethylene exchange were also analyzed. Results: We identified 11 patients with acute hematogenous PJI who underwent I&D/ polyethylene exchange with retention of metal components. The average time from onset of symptoms to I&D/ polyethylene exchange was 11.55 days +/-5.57. The mean follow-up after this surgery was 2.8 years +/-1.45. The long-term failure rate was 50%. The most common bacteria isolated in patients who failed was Methicillin Resistant Staphylococcus Aureus (MRSA). The most common bacteria isolated in patients who retained their implants was Methicillin Sensitive Staphylococcus Aureus(MSSA). Visual Analog Scale (VAS), Short Musculoskeletal Function Assessment (SMFA), Short Form-36 (SF36), and American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot scale showed significant improvement when compared to preoperative scores in patients who retained their implants both after primary and after I&D and polyethylene exchange. Conclusion: I&D and polyethylene exchange with retention of metal components has comparable long-term survivorship to those reported in the Knee and Hip Arthroplasty literature. Patient reported outcomes after I&D and polyethylene exchange were comparable to those collected after primary arthroplasty in patients who ultimately retained their implants. Two variables which were independent predictors of failure of this surgery include duration of symptoms prior to I&D as well as organism isolated on culture. With a failure rate of 50%, the authors recommend thorough evaluation on a case by case basis prior to indicating a patient for single stage I&D with polyethylene exchange.

Background: Acute hematogenous periprosthetic joint infection (PJI) is defined in the literature as infection diagnosed and treated within 2 to 4 weeks from the onset of symptoms. In total hip and knee arthroplasty, irrigation and debridement (I&D) and polyethylene exchange with component retention has been studied extensively. However, there is minimal literature evaluating this treatment method for PJI in total ankle arthroplasty (TAA). The purpose of this study was to evaluate both the clinical and patient-reported outcomes and survivorship of TAA acute hematogenous PJIs treated with I&D and polyethylene exchange. Methods: A single-center, retrospective chart review of prospectively collected data in patients with TAA PJI who subsequently underwent I&D and polyethylene exchange with retention of metal components was conducted. The primary outcome was failure rate of I&D and polyethylene exchange, where failure was defined as subsequent removal of all components and 2-stage revision or arthrodesis. Patient-reported outcomes collected before primary arthroplasty, after primary arthroplasty, and after polyethylene exchange were also analyzed. Results: We identified 14 patients with acute hematogenous PJI who underwent I&D and polyethylene exchange with retention of metal components. The mean time from primary TAA to symptoms was 43 months (range 1-147 months). The average time from onset of symptoms to I&D and polyethylene exchange was 11.4 ± 5.6 days. The mean follow-up after this surgery was 2.8 ± 1.5 years. The long-term failure rate was 54%. The most common bacteria isolated in patients who failed was methicillin-resistant Staphylococcus aureus (MRSA). The most common bacteria isolated in patients who retained their implants was methicillin-sensitive Staphylococcus aureus (MSSA). Visual analog scale (VAS), Short Musculoskeletal Function Assessment (SMFA), Short Form-36 (SF-36), and American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot scale showed significant improvement when compared to preoperative scores in patients who retained their implants both after primary and after I&D and polyethylene exchange. Conclusions: I&D and polyethylene exchange with retention of metal components has a long-term survivorship comparable to those reported in the total knee and total hip arthroplasty literature. Patient-reported outcomes after I&D and polyethylene exchange were comparable to those collected after primary arthroplasty in those patients who ultimately retained their implants. Two variables in this cohort that were associated with I&D and polyethylene exchange failure include time the patient was symptomatic prior to I&D as well as organism isolated on culture. With a failure rate of 54%, the authors recommend thorough evaluation on a case-by-case basis prior to indicating a patient for single-stage I&D with polyethylene exchange. Levels of Evidence: Level IV, case series.

Category: Ankle Arthritis Introduction/Purpose: With the increasing use of total ankle arthroplasty (TAA), new implants with varied configurations are being developed every year. This study aims to provide the early complications, reoperations and radiographic and clinical outcomes of the Infinity TAA. To date, clinical results of this novel fixed-bearing implant have not been published. Methods: A retrospective analysis of 64 consecutive ankles that underwent a primary Infinity TAA from July 2014 to April 2016 was performed. Patients had an average follow-up of 24.5 (range, 18-39) months. Medical records were reviewed to determine the incidence of complications, reoperations and revisions. Radiographic outcomes included preoperative and postoperative tibiotalar alignment, tibial implant positioning, the presence of periprosthetic radiolucency and cysts, and evidence of subsidence or loosening. Additionally, patient-reported outcomes were analyzed with the Foot and Ankle Outcome Score (FAOS) preoperatively and 1-year postoperatively. Results: Survivorship of the implant was 95.3%. Fourteen ankles (21.8%) presented a total of 17 complications (Table 1). A total of 12 reoperations were necessary in 11 ankles (17.1%). Revision surgery was indicated for 3 ankles (4.7%) due to isolated subsidence of the tibial implant in 2 cases and due to subsidence of both the tibial and talar components in 1 case. Tibiotalar coronal deformity was significantly improved after surgery (P < .0001) and maintained during latest follow-up (P = .81). Periprosthetic radiolucent lines were observed around the tibial component in 20 ankles (31%) and around the talar component in 2 ankles (3.1%). A tibial cyst was observed in 1 ankle (1.5%). Outcome scores were significantly improved for all FAOS components analyzed (P < .0001). Conclusion: Most complications observed in the study were minor and successfully treated with a single reoperation procedure or nonoperatively. Failures and radiographic abnormalities were most commonly related to the tibial implant. Further studies with longer follow-up are needed to evaluate the survivorship of the tibial implant in the long-term.

Background: Prosthetic joint infection (PJI) after total ankle arthroplasty (TAA) is a serious complication that results in significant consequences to the patient and threatens the survival of the ankle replacement. PJI in TAA may require debridement, placement of antibiotic spacer, revision arthroplasty, conversion to arthrodesis, or potentially below the knee amputation. While the practice of TAA has gained popularity in recent years, there is some minimal data regarding wound complications in acute or chronic PJI of TAA. However, of the limited studies that describe complications of PJI of TAA, even fewer studies describe the criteria used in diagnosing PJI. This review will cover the current available literature regarding total ankle arthroplasty infection and will propose a model for treatment options for acute and chronic PJI in TAA. Methods: A review of the current literature was conducted to identify clinical investigations in which prosthetic joint infections occurred in total ankle arthroplasty with associated clinical findings, radiographic imaging, and functional outcomes. The electronic databases for all peer-reviewed published works available through January 31, 2018, of the Cochrane Library, PubMed MEDLINE, and Google Scholar were explored using the following search terms and Boolean operators: “total ankle replacement” OR “total ankle arthroplasty” AND “periprosthetic joint infection” AND “diagnosis” OR “diagnostic criteria.” An article was considered eligible for inclusion if it concerned diagnostic criteria of acute or chronic periprosthetic joint infection of total ankle arthroplasty regardless of the number of patients treated, type of TAA utilized, conclusion, or level of evidence of study. Results: No studies were found in the review of the literature describing criteria for diagnosing PJI specific to TAA. Conclusions: Literature describing the diagnosis and treatment of PJI in TAA is entirely reliant on the literature surrounding knee and hip arthroplasty. Because of the limited volume of total ankle arthroplasty in comparison to knee and hip arthroplasty, no studies to our knowledge exist describing diagnostic criteria specific to total ankle arthroplasty with associated reliability. Large multicenter trials may be required to obtain the volume necessary to accurately describe diagnostic criteria of PJI specific to TAA. Level of Evidence: Level III, systematic review.

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.

Category: Ankle Arthritis; Ankle Introduction/Purpose: Total ankle arthroplasty (TAA) has garnered significant interest and increased use over the past decade, with advancements made in both design and surgical technique. The main advantage of TAA for the surgical treatment of ankle arthritis is to preserve range of motion compared to ankle arthrodesis. Among the criteria guiding the choice between arthroplasty and arthrodesis, the long-term survival and postoperative outcomes are of crucial importance. The Salto Talaris is a fixed-bearing implant first approved in the US in 2006, and long-term survivorship data is limited. The purpose of this study is to determine minimum 5-year survivorship of the Salto Talaris prosthesis and causes of failure. In addition, we evaluate long-term radiographic and patient-reported outcomes. Methods: We retrospectively identified 86 prospectively followed patients from 2007 to 2014 who underwent TAA with the Salto Talaris prosthesis at our institution. Of these, 81 patients (84 feet) had a minimum follow-up of 5 years (mean, 7.1; range, 5 to 12). Mean age was 63.5 years (range, 42 to 82) and mean BMI was 28.1 (range, 17.9 to 41.2). Survivorship was determined by incidence of revision, defined as removal/exchange of a metal component. Chart review was performed to record incidences of revision and reoperation. Preoperative, immediate and minimum 5-year postoperative x-rays were reviewed; coronal tibiotalar alignment (TTA) was measured on standing AP radiographs to assess alignment of the prosthesis. A TTA of +-5° from 90° indicated neutral alignment, while <85° and >95° was considered varus and valgus alignment, respectively. Radiographic subsidence as well as presence and location of periprosthetic cysts were documented. Pre- and minimum 5-year FAOS domains were compared. Results: Survivorship was 97.6% with two 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 19.5% (18) with the main reoperation being exostectomy with debridement for ankle impingement (12). Average preoperative TTA was 88.8° with 48 neutral (average TTA of 90.1°), 18 varus (82.3°) and 8 valgus (99.6°) ankles. Average postoperative TTA was 89.0° with 69 neutral (89.7°), 6 varus (83°), and 1 valgus ankle (99.3°). Radiographic subsidence was observed in one patient who underwent revision, and periprosthetic cysts were observed in 18 patients. There was significant improvement in all FAOS domains at final follow-up. Conclusion: This is the largest study to date dedicated to evaluating survivorship of the Salto Talaris prosthesis. Our data reflects a high survival rate and moderate reoperation rate with long-term follow-up of the Salto Talaris implant. We observed significant improvement in radiographic alignment as well as patient-reported clinical outcomes at minimum 5-year 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]
