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, Ankle Arthritis Introduction/Purpose: Primary ankle osteoarthritis is very uncomon, in fact 70-78% of the case ankle arthritis has a post- traumatic cause. Ankle arthrodesis (AA), has been considered a reliable procedure for resolution of ankle osteoarthritis. Recent modifications in Total ankle replacement (TAR) designs have challenged the perception that AA is the treatment of choice for end-stage ankle arthritis. Trabecular Metal Total Ankle system is a fixed-bearing prosthesis. The new design is flanked by use of new materials. The tibial articular surface is constructed of highly crosslinked UHMWPE and Trabecular Metal lining the talar and the tibial base component. The purpose of this retrospective study was to show the preliminary result in 31 patients underwent to ankle replacement using Zimmer Trabecular Metal Total Ankle system. Methods: We retrospectively assessed prospectively collected data on the initial cohort of 31 patients undergoing TAR with this implant. Clinical evaluation was determined pre and postoperatively for a minimum of 24 months after surgery. Pain was rated using the visual analogue scale (VAS). Functional results were assessed as well as ankle range of motion (ROM). Clinical outcomes used where the Short Form SF-12 Quality of Life score, the American Foot and Ankle Society (AOFAS). The imaging follow-up included ankle radiographs done at 6, 12 and 24 months. Radiological parameters were angles??(normal values 90 +- 2),?? (normal value 85 +- 2),??? normal values 20 +- 2) and TTratio? normal values: 27% to 42%). Results: The study included 31 ankles of TM Ankle Replacement in 31 consecutive patients over a period of 2 years (2013–2015). Out of 31 patients, 13 were females and 18 were males (average age 49.4 years, range, 30–75 years). All procedures were performed by a single surgeon. The ROM plantarflexion and dorsiflexion improved significantly (p <0.001) at the last follow up. The mean VAS pain score decreased significantly from 7.42 points (range 4 – 10 points) preoperatively to 1.42 points (range, 0 - 3 points) at the time of the latest follow-up (p <0.001). AOFAS and SF-12 scores both improved from postoperatively to the last follow up. (Table 1). We noted stable implants based on our radiographic parameters, with no corrections loosening. (Table 2) Conclusion: Our study evaluated the new fixed bearing Zimmer TM total ankle replacement approved by the US FDA in 2012 and is the first studies to evaluate the clinical and radiographic outcomes of this prosthesis. Of 31 ankles treated with a new transfibular arthroplasty system, only two asymptomatic fibular delayed union were registered. No implant failure was noted at 24 months postoperatively. Four ankles underwent secondary surgery for symptomatic fibular hardware with good outcome. The findings suggest that this total ankle system is safe and effective at short-term follow-up.

Background: The Integra Cadence total ankle replacement (TAR) is a fourth-generation anatomic, fixed-bearing implant requiring minimal tibial and talar resection, which has been in clinical use since June 2016. The primary purpose of this study is to assess its short-term clinical and radiographic outcomes after TAR using this prosthesis. Methods: This is a prospective case series of consecutive patients that underwent TAR using this novel fourth-generation prosthesis between June 2016 and November 2017. The primary outcome of interest was the Ankle Osteoarthritis Scale (AOS). Secondary outcomes included Short Form Health Survey–36 (SF-36) scores, radiographic alignment, complications, reoperations, and revisions. Results: In total, 69 patients were included in our study. Fifty-one patients (73.9%) required a total of 91 ancillary procedures. Postoperatively, AOS pain scores decreased significantly by an average of 17.8±30.1 points from 45.9±18.2 to 28.4±27.3 ( P < .001). AOS disability scores also decreased significantly following surgery by an average of 22.0±30.5 points from 53.9±18.5 to 32.5±27.9 ( P < .001). The SF-36 physical component summary score improved 10.4±9.8 points from 33.1±9.1 to 42.6±9.1 ( P < .001). Radiographic analysis demonstrated significant improvement to neutral coronal plane alignment, which was achieved in 97% of patients ( P < .01) with no cyst formation at 2 years. There was 1 reported complication, 9 reoperations, and no metal or polyethylene component revisions. Overall, the 2-year implant survivorship was 100% in our cohort. Eighteen patients (26.1%) demonstrated fibrous ingrowth of the tibial component. However, outcome scores for these patients did not demonstrate any negative effects. Conclusions: In our hands, this TAR system demonstrated excellent early clinical and radiographic outcomes. Patients reported improved physical health status, pain, and disability in the postoperative period. Total ankle instrumentation allowed for accurate and reproducible implantation with correction of coronal and sagittal plane deformities. Early results for the clinical use of this TAR system are promising, but further long-term prospective outcome studies are necessary. Level of Evidence: Level IV, case series.

Category: Ankle Arthritis; Ankle Introduction/Purpose: The Inbone Total Ankle Replacement System (Wright) is a modular stemmed ankle replacement, it is marketed as for both primary and revision TAR, it has been in use at Nottingham since 2016 mainly for revisions, we are reporting our experience with this system and our early results. Methods: This is a retrospective study with prospective collected data. We identified 27 (18M/9F) patients who had Inbone 2 TAR for revision surgery during the period August 2016 -March 2019. The mean follow up was 21 months (7-38months). Mean age of 69 years (51-81).All ankle revisions were a single-stage revision apart from 1 patient who had a 2 stage revision as at the first stage infection was suspected, it was left with a cement spacer and when all samples came back negative the second stage was carried out.All patients had follow up appointments at 6 weeks, 3,6 and 12 months. Patients were required to fill in MOXFQ questioner and all had weight-bearing radiographs on every follow up appointment.The indication for the surgery was aseptic Loosening 23, Malalignment 1 Insert wear 2 and heterotopic ossification 1. Results: 20 patients had concurrent procedure during the surgery(Table 1). There was 1 deep wound infection that required DAIR procedure 3 weeks after the revision surgery and has gone to make full recovery, no other complication were reported.Improvement in clinical outcome and PROMS data was noted on follow up, MOXFQ for Pain improved from 70 pre op to 34 at 6 months and 32 at 1 year(p<0.001 paired t test),The outcome for Walking improved from 69 pre op to 41 at 6 months and 40 at 1 year(p<0.001 paired t test).Radiological alignment was maintained in all ankles both in the coronal and the sagittal plain, posterior heterotopic ossification was noted in 8(29%), No loosening or signs of failure at any follow up appointment Conclusion: This is one of the largest series of this implant used in revision TAR. Our early results show considerable improvement in patient outcomes with very low complications and no failures.This implant provides a good option as a revision implant and our view that it is a superior solution to ankle fusions for failed total ankle replacements [Table: see text]
