Abstract
Jones type fifth metatarsal fractures pose a challenge to the foot and ankle surgeon, given documented high nonunion rates as well as high complication rates including hardware prominence, nerve injury, and screw breakage for existing treatment modalities including screw and plantar plate fixation. We call for the design of innovative Jones-fracture specific implants which contour to the natural curve of the fifth metatarsal. Future research should aim to expand upon existing literature for Jones fracture fixation and evaluate efficacy of novel implants which are designed to address unacceptably high complication rates for existing treatment modalities.

Orthop J Sports Med 2022; 10:23259671221079637. [PMID: 35284583 PMCID: PMC8905068 DOI: 10.1177/23259671221079637] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Accepted: 12/31/2021] [Indexed: 11/26/2022] Open
Abstract
Background: Considerable variability exists in return-to-play rates after anterior cruciate ligament (ACL) injury and reconstruction (ACLR) among National Football League (NFL) players of different positions. Purpose/Hypothesis: The purpose of this study was to compare return-to-play and performance levels by position in NFL players after ACLR. It was hypothesized that (1) ACL injuries have significant effects on the careers of NFL players, including return to play and performance, and (2) players of certain positions that involve relatively less pivoting and cutting perform better after ACLR. Study Design: Descriptive epidemiology study. Methods: All NFL players who underwent ACLR between 2013 and 2018 were identified using the FantasyData injury database. Player characteristics, snap count, games played, games started, and performance metrics were collected for 3 years before and after injury using the Pro Football Reference database. Performance was measured using an approximate value (AV) algorithm to compare performance across positions and over time. Nonparametric tests were used to compare the pre- and postinjury data and the percentage change in performance between different positions. Results: Overall, 312 NFL players were included in this study, and 174 (55.8%) returned to play. Of the eligible players, only 28.5% (n = 59/207) remained in the league 3 years postinjury. Within the first 3 years postinjury, players played in fewer games (8.7 vs 13.7; P < .0001), started in fewer games (3.0 vs 8.3; P < .0001), had lower AVs (1.5 vs 4.3; P < .0001), and had decreased snap counts (259.0 vs 619.0; P < .0001) compared with preinjury. Quarterbacks were most likely to return to play (92.9% vs 53.7%; P = .0040) and to return to performance (2% vs 50% decrease in AV; P = .0165) compared with the other positions. Running backs had the largest decrease in AV (90.5%), followed by defensive linemen (76.2%) and linebackers (62.5%). Conclusion: The study findings indicated that NFL players are severely affected by ACL injury, with only 28.5% still active in the league 3 years after the injury. Running backs, defensive linemen, and linebackers performed the worst after injury. Quarterbacks were most likely to return to play and had superior postinjury performance compared with the other positions.

Abstract
Medical malpractice lawsuits can place significant economic and psychologic burden on a provider. Orthopedic surgery is one of the most common subspecialties involved in malpractice claims. There is currently no study examining malpractice lawsuits within foot and ankle surgery. Accordingly, the purpose of this work is to examine trends in malpractice claims in foot and ankle surgery. The Westlaw legal database was queried for lawsuits pertaining to foot and ankle surgery from 2008 to 2018. Only cases involving medical malpractice were included for analysis. All available details pertaining to the cases were collected. This included plaintiff demographic and geographic data. Details regarding the cases were also collected such as anatomical location, pathology, complications, and case outcomes. Forty-nine malpractice lawsuits pertaining to foot and ankle were identified. Most plaintiffs in these cases were adult females, and the majority of cases occurred in the northeast (53.1%). The most common anatomical region involved in claims involved the forefoot (29%). The majority of these claims involved surgery (65%). Infection was the most common complication seen in claims (22%). The jury ruled in favor of the defendant surgeon in most cases (73%). This is the first study to examine trends in medical malpractice within foot and ankle surgery. Infection was the most frequent complication seen in claims and forefoot surgery was the most common anatomic location. A large portion of claims resulted after nonoperative treatment. A better understanding of the trends within malpractice claims is crucial to developing strategies for prevention.

Abstract
Introduction: COVID-19 is among the most deleterious pandemics that the world has ever faced. It is known that SARS-CoV-2 engenders its effects by triggering a massive immune response identified as a “cytokine storm,” but the full extent of clinical manifestations of the disease is still not understood. Case Presentation:We report the first case of a patient with COVID-19 infection who developed inflammatory (IL) aseptic arthropathy. The patient is a South Asian male of Indian origin residing in the United States. Conclusion: This case demonstrates the importance of remaining vigilant about the new and unique manners, in which COVID-19 may present itself. Providers should be aware of the possible development of IL arthropathy in patients with the disease. Keywords: COVID-19, inflammatory arthropathy, aseptic arthropathy, musculoskeletal sequelae.

Abstract
Introduction. Segmental bone loss in the hindfoot hinders the chance of successful outcomes. Tibiotalocalcaneal arthrodesis is a reliable option; nevertheless, the risk of nonunion is high. Three-dimensional (3D) printed titanium implants offer a strong scaffold that can be customized and has demonstrated encouraging healing rates. In this study, we described the clinical outcomes and the radiologic union rate of a case series of patients with hindfoot arthrodesis, using a retrograde intramedullary nail associated to a 3D printed titanium cage. Methods. Seven patients undergoing hindfoot arthrodesis, using a retrograde intramedullary nail associated to a custom 3D printed titanium cage, were included. Demographic data were collected. Functional outcomes were assessed using the American Orthopedic Foot and Ankle Score and the Visual Analogue Scale for pain. Hindfoot alignment and radiographic union were evaluated using weight-bearing radiographs and computed tomography scan, respectively. Results. A total of 6 (85%) patients had more than 50% bony bridging. Only 1 patient underwent below knee amputation due to recurrence of chronic osteomyelitis. Two additional patients had minor complications. Conclusion. Tibiotalocalcaneal arthrodesis using customized titanium cages for patients with large bone defects has shown a high rate of union in those at risk of nonunion. However, further research with larger series is needed.Levels of Evidence: Level IV: Case series.

Abstract
BACKGROUND Subchondroplasty (SCP) is a relatively new procedure, developed in 2007 for the treatment of bone marrow lesions (BMLs), that has shown promising results in the knee through several different case series. The foot and ankle literature, however, is sparse, with only a few documented case reports or case series. At our institution, we have identified several patients with complications after this specific procedure. As a result, we report our case series of patients who developed talar avascular necrosis (AVN) after undergoing SCP. METHODS A retrospective review was performed of patients who underwent SCP for a talar BML at our facility or who were referred to our facility after undergoing SCP at an outside institution. Patients were included if they developed radiographic evidence of talar AVN after the procedure. Patient demographics, comorbidities, concomitant intraoperative procedures, complications, and subsequent interventions were reviewed. RESULTS Seven patients were identified as having radiographic evidence of talar AVN after SCP. Average time interval was 23 months postoperative from index procedure to radiographic confirmation of AVN. Two of the index procedures were performed at our institution, whereas 5 of the index procedures were performed at outside institutions and referred for further management. Three patients had documented risk factors for AVN before the SCP procedure. All 7 patients were symptomatic from the AVN. CONCLUSION We identified 7 patients who went on to develop talar AVN after having undergone SCP. LEVEL OF EVIDENCE Level IV, case series.

Abstract
Three-dimensional (3D) printing has greatly benefited medicine, manufacturing vital organs like skin, hearts, kidneys, and livers. Early studies on 3D printing in surgery have consistently reported decreased operative time and improved precision. This technology has gained popularity with orthopaedic surgeons in knee, hip, and shoulder surgeries because 3D printing is associated with enhancing osseointegration. However, this innovation is still not commonly used among foot and ankle surgeons; one reason is that whereas the literature on 3D printing-assisted surgery is populated with studies on operative techniques and clinical outcomes, there exists an ambiguity on how to incorporate this feature into the clinic. Thus, the aim of this technology column is to consolidate and standardize a workflow to guide foot and ankle surgeons on integrating 3D printing into one's practice. We describe a model developed by a single surgeon at one institution who directs a large caseload of 3D-printed foot and ankle surgeries. From the initial patient visit to the interaction between the surgeon and the implant engineering team, to documentation of data adding to the preliminary literature, this work has great implications on streamlining the assimilation of a highly successful technology to improve foot and ankle surgery for both surgeons and patients.Level of Evidence: Level V.

Abstract
Peroneal tendon disorders remain an often overlooked source of lateral hindfoot pain and tenderness. Medical professionals who specialize in foot and ankle care are still far more likely to diagnose a peroneal tendon disorder as an ankle injury. In fact, acute peroneal dislocations are misdiagnosed in up to 40% of cases. The major subsets of peroneal disorders include peroneal tendonitis and tenosynovitis, painful os peroneum syndrome, subluxation, and tearing of the peroneal tendons. Proper history and physical exam maneuvers must be performed to help identify the source of the injury and differentiate these categories. Detailed imaging through X-ray and magnetic resonance imaging must also be used to diagnose the etiology of the patient's condition in order to direct management. Currently, there is very limited knowledge on peroneal pathologies, and treatment protocol is highly variable and limited to expert opinion. Despite the individual preferences and nuances held by each surgeon when it comes to operating, the overarching principles that guide appropriate management of tendonitis, subluxation, and tendon tear should maintain a higher level of consistency. Therefore, the authors of this review aim to elucidate the most current methods to diagnose these disorders as well as evidence-based practices for optimal management.Levels of Evidence: Level V.

Abstract
BACKGROUND We report the clinical outcomes and complications following our limited open incision Achilles tendon repair technique without instrument guides. METHODS A total of 33 patients were included in this study. We recorded pre- and postoperative scores on the Foot and Ankle Disability Index (FADI), visual analog scale (VAS), and the Foot and Ankle Outcome Score (FAOS). Subgroup analyses were performed for acute (<2 weeks) and subacute (2-6 weeks) Achilles tendon repairs. A P value <.05 was considered significant for all statistical analyses. RESULTS The median time from injury to surgery was 10.0 days (range, 1-45 days). At a median follow-up of 3.7 years (range, 1.0-9.8 years), the average pre- and postoperative outcome scores improved significantly for the following: FADI index (49.1-98.4, P < .001), VAS (4.8-0.2, P < .001), FAOS Pain (54.8-99.2, P < .001), FAOS Symptoms (84.6-97.0, P < .001), FAOS activities of daily living (61.4-97.2, P < .001), FAOS Sports and Recreational Activity (39.5-98.5, P < .001), and FAOS quality of life (39.7-88.7, P < .001). There were no significant differences between pre- and postoperative outcome scores between the acute and subacute Achilles repair groups. There were no wound complication, reruptures, or reoperations in the entire cohort. CONCLUSION Patients showed improvements in postoperative patient-reported outcome scores with minimal complications. There was no significant difference in outcomes for acute vs subacute repairs. Our limited open incision Achilles tendon repair, which required no additional targeting instrumentation, had favorable midterm results. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
Although there is growing evidence supporting posterior-based surgical approaches to open reduction internal fixation (ORIF) of malleolar fractures, the lateral approach still remains the standard of care for this injury. The purpose of this review was to integrate the results of several studies investigating outcomes following posterior-based approaches to the ORIF of malleolar fractures. The literature search was undertaken using PubMed, the Cochrane Library, and Embase. Crude event rates for fracture healing and postoperative complications were calculated. When possible, meta-analyses were conducted to estimate the relative risk of these outcomes between patients treated by posterior-based approaches versus other approaches to ORIF of malleolar fractures. Twenty-two studies were eligible, and 4 studies were included in the meta-analyses. The healing rate was 100% in all patients, regardless of the surgical approach. Overall, 1.26% of patients developed an infection, 0.63% required reoperation, 1.13% experienced aseptic loosening, 5.53% experienced pain after treatment, and 2.52% experienced symptomatic hardware. No malunion or heterotopic ossification was reported in any study. Among patients treated with a posterior-based approach, the most frequently reported complication was infection (2.50%), with lower rates of reoperation and postoperative pain. Patients with trimalleolar fractures experienced slightly poorer outcomes. Patients treated by posterior-based approaches had a significantly increased risk of infection (p = .010) relative to those treated by the lateral approach; patients treated by the lateral approach had a significantly increased risk of pain after surgery (p = .004) and symptomatic hardware (p = .007). This study brought together evidence that posterior-based surgical approaches and non-posterior-based approaches to ORIF are effective in healing malleolar fractures, with significant differences in specific postoperative complications that need to be further explored.

Abstract
BACKGROUND Talus avascular necrosis (AVN) is a challenging entity to treat. Management options depend on disease severity and functional goals. Total talus replacement (TTR) is a treatment option that maintains joint range of motion. The literature on TTR is limited with variability in implant design and material. The purpose of this study was to evaluate outcomes following TTR with a custom 3D printed metal implant. METHODS Patients who underwent TTR were retrospectively reviewed over a 3-year period. Basic demographic data and comorbidities were collected. Medical records were reviewed to obtain postoperative and preoperative visual analog scale (VAS) scores, Foot and Ankle Outcome Scores (FAOSs), ankle range of motion, and postoperative complications. Statistical analysis was conducted to compare clinical and patient-reported outcomes pre- and postoperatively. Twenty-seven patients underwent TTR for talar AVN with a mean follow-up of 22.2 months. RESULTS Ankle range of motion remained unchanged postoperatively. VAS pain scores improved postoperatively from 7.1 to 3.9 (P < .001). FAOSs improved postoperatively with regard to pain (P < .001), symptoms (P = .001), quality of life (P < .001), and activities of daily living (P < .001). There were 3 complications requiring reoperation in this cohort. CONCLUSION 3D printed TTRs represent a unique surgical option for patients with severe talar AVN. Patients in this cohort demonstrated significant improvements in pain scores and patient-reported outcomes. TTR allows for symptomatic improvement with the preservation of motion in individuals with talar collapse and AVN. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
BACKGROUND Patients with talar avascular necrosis (AVN) have limited treatment options to manage their symptoms. Historically, surgical options have been limited and can leave patients with little ankle motion and have high failure rates. The use of custom 3D printed total talar replacements (TTRs) has arisen as a treatment option for these patients, possibly allowing better preservation of hindfoot motion. We hypothesized that patients undergoing TTR will demonstrate a statistically significant improvement in Foot and Ankle Outcome Score (FAOS) at 1 year after surgery. METHODS We retrospectively reviewed 15 patients who underwent a TTR over a 2-year period. Patient outcomes were reviewed, including age, sex, comorbidities, etiology of talar pathology, number and type of prior surgeries, radiographic alignment, FAOS and Visual Analog Scale (VAS) score, and range of motion. Data analysis was performed with Student t-tests and multivariate regression. RESULTS FAOSs and VAS scores showed statistically significant improvements postoperatively as compared with preoperative scores. There was a statistically significant decrease in VAS pain scores from 7.0 preoperatively to 3.6 (P < .001). Average follow-up was 12.8 months. With the number of patients available, there was no statistically significant change in radiographic alignment parameters postoperatively as compared with preoperatively (P values ranged from .225 to .617). CONCLUSION Our hypothesis that these patients show statistically significant improvements in FAOSs at 1 year was confirmed. TTR represents an exciting treatment option for patients with talar AVN, though longer-term follow-up is needed.Level of Evidence: Level IV: Case series.

Abstract
Significance: Continuous external tissue expansion (CETE) is a versatile tool in soft tissue injury management, and could be an addition to the traditional reconstructive ladder. Recent Advances: This critical review discusses the principles and application of CETE, covering a company-sponsored consensus meeting on this emerging technology and highlighting the DermaClose® (Synovis Micro Companies Alliance, Inc., Birmingham, AL) device's unique approach to soft tissue injury management. There is clinical evidence to support the use of CETE in the management of a number of wound types, including fasciotomy, trauma, amputation, and flap donor sites. The device can be applied to open wounds, potentially avoiding the need for a skin graft or other more complex or invasive reconstruction options. DermaClose applies constant tension without restricting blood flow and does not require repeated tightening. Critical Issues: CETE is becoming more widely used by surgeons of different specialties, and numerous reports describing its efficacy and safety in wound management have been published. Surgeons using CETE must follow the correct technique and select patients carefully to achieve optimal outcomes. However, there is no single source of information or consensus recommendations regarding CETE application. Future Directions: Prospective evidence on the efficacy and safety of CETE in clinical practice is required to communicate the best techniques and share important experiences. This will help to solidify its place in the reconstructive ladder as a valuable additional option for surgeons.

Abstract
BACKGROUND Suture anchors have been used for soft tissue repair in orthopedic surgery for decades. Recently, bioabsorbable suture anchors have increased in popularity and have spurred the introduction of ultrasound-assisted systems. The purpose of our study was to determine the clinical safety and efficacy of a new ultrasound-assisted suture anchor system for foot and ankle procedures. METHODS We retrospectively reviewed 50 cases using the ultrasound-assisted suture anchor with at least 24 months of follow-up. We reviewed demographic data including comorbidities, type of procedure, adverse events, and clinical outcomes using the Foot and Ankle Outcome Score (FAOS) and visual analog scale (VAS) score. We divided complications into minor and major, with major complications requiring revision surgery or leading to long-term morbidity. Our primary outcome was complication rates and our secondary outcome was improvement in clinical scores. RESULTS The most frequent cases using the anchor included lateral ankle ligament reconstruction (n = 19), insertional Achilles repair (n = 15), lateral ligament reconstruction in conjunction with a total ankle arthroplasty (n = 6), and plantar plate repair (n = 3). There were 5 superficial wound infections that resolved with wound care and/or oral antibiotics. There were 3 major complications (6%): a deep wound infection that required an irrigation and debridement, a deep venous thrombosis, and a recurrence of varus deformity in a patient who underwent a total ankle arthroplasty with lateral ligament reconstruction. Only the varus deformity recurrence case could possibly be directly linked to the suture anchor (2% of all cases). VAS scores improved from 6.0 to 1.2 (P < .001) and FAOS improved from 54.7 to 94.2 (P < .001). CONCLUSION This bioabsorbable anchor was a safe device with low failure rates, and it was used for soft tissue repair cases in the foot and ankle with successful clinical outcomes.

Abstract
Background. Tibiotalocalcaneal (TTC) arthrodesis is a common treatment option for hindfoot arthritis and deformity. Loss of compression over time with statically locked nails may contribute to nonunion. A novel retrograde intramedullary nail with an internal pseudoelastic component has recently been used to provide sustained dynamic compression (SDC). The purpose of this study was to compare fusion rates and time to union between the SDC and nondynamized (ND) nails. Methods. All patients who underwent TTC arthrodesis with an intramedullary nail at a single institution from 2013 to 2017 and who had at least 1 year of follow-up were included in this study. Baseline patient and operative characteristics were collected and compared between the sustained SDC and ND nail groups. The rate of successful fusion, time to union, and complications were compared between the groups. Results. The SDC cohort had a significantly faster time to union by 3.9 months (P = .049). The SDC cohort had a higher fusion rate (78.0%) compared with the ND nail cohort (75.0%), although this was not statistically significant (P = .75). The SDC nail was used significantly (P < .05) more often in patients with known risk factors for nonunion, including female sex, smoking, revision surgery, prior trauma, and patients requiring 3D cage implants for significant bone loss. There were no differences between the groups in terms of complications. Conclusion. The SDC nail has been shown to achieve successful arthrodesis in a population at high risk for nonunion, using less hardware, and at a faster rate than ND nails.

Abstract
Avascular necrosis (AVN) of the talus remains a clinical challenge with suboptimal outcomes after treatment. In cases of extensive disease, the insufficient blood supply leads to a high rate of complications including non-union after surgical treatment. This, in conjunction with the development of premature adjacent arthritis represents a challenge for the treating surgeon. Nowadays, total ankle arthroplasty is a reasonable option for the treatment of end-stage ankle arthritis with improved short- and long-term outcomes. We present a technique for patients with end-stage ankle arthritis associated to extensive talar osteonecrosis, and patients with prior total ankle replacement and talar component collapse due to AVN. This technique provides a more anatomic treatment for patients with severely deficient bone stock due to talar necrosis with ankle arthritis or failed ankle replacement. Nonetheless, evaluation of the outcomes at long-term is needed. (Journal of Surgical Orthopaedic Advances 29(4):244-248, 2020).

Abstract
In recent years, it has become increasingly important for physicians to understand the healthcare system holistically. Thus, some physicians have sought formal education in business through a Master's in Business Administration (MBA). In this study, we looked specifically at orthopedic MD-MBAs and their career trajectories. We conducted a cross-sectional study of 127 orthopedic surgeons who have both MD and MBA degrees. Through online searches and phone calls, we compiled information regarding years in practice, fellowship training, practice type, non-clinical roles, and business school education. Almost all (96.85%) orthopedic MD-MBAs identified are still practicing clinically. The most common nonclinical roles are administration (38.58%), industry consulting (20.47%), and entrepreneurship (11.02%). Most (65.35%) pursued MBAs after medical school, but dual-degree programs are increasing in popularity. Almost all (88.57%) graduates of such programs have been practicing for less than 15 years. Orthopedic surgeons participate in a variety of nonclinical roles including administration, consulting, and entrepreneurship. For those currently in training, it is important to recognize the many opportunities that exist and the potential paths to pursuing them.

Abstract
Background. Lateral malleolus (LM) fixation is necessary for unstable ankle fractures. Traditional fixation relies on the use of plates through a lateral incision, wound healing can be an issue for such incisions. A novel intramedullary (IM) fixation device has been developed that can be placed through a minimal incision. The purpose of this study was to demonstrate the clinical efficacy of this device. Methods. A retrospective analysis was performed on patients who received IM fixation for isolated fibula, bimalleolar (BM), and trimalleolar (TM) fractures. Pertinent demographic information, operative factors, complications, and clinical outcomes were recorded. Results. Sixteen patients were included in the study with an average age of 59 years (range 35-86 years). Six patients presented with isolated LM fractures, four patients had a BM fracture with a syndesmotic injury, 2 patients sustained a LM fracture with an associated syndesmotic injury, 2 patients had a BM fracture, and 2 patients had a TM fracture with a syndesmotic injury. There was a 100% healing rate of the lateral malleolus without any cases of malunion or shortening. There were no cases of sural nerve or peroneal tendon injuries, nor any wound complications found. Conclusion. These findings demonstrate the safe and efficacious use of a novel intramedullary fixation device for fibula fractures with lower wound complications compared with published outcomes found with lateral fibular plating. The features of this device allow for reliable fixation of the fibula, maintaining length and minimizing wound issues. Levels of Evidence: Level IV: Case series.

Abstract
RECOMMENDATION We recommend that aspiration of the ankle with an antibiotic spacer prior to a second-stage reimplantation be strongly considered. Available studies indicate that a positive culture of the aspirate in this setting is predictive of residual infection, while a negative aspirate culture does not rule out infection and should be interpreted in light of other clinical indicators and laboratory values. LEVEL OF EVIDENCE Consensus. DELEGATE VOTE Agree: 92%, Disagree: 8%, Abstain: 0% (Super Majority, Strong Consensus).

Abstract
Distal Chevron osteotomy is a well-established surgical procedure for mild to moderate hallux valgus deformity. Many methods have been described for fixation of osteotomy site; secure fixation, enabling large displacement of the metatarsal head, is one of the essentials of this procedure. The purpose of the present study was to evaluate the short-term radiographic outcome of a distal Chevron osteotomy using an intramedullary plate for the correction of hallux valgus deformity. The present study evaluated 37 patients (40 feet) who underwent distal Chevron osteotomy using an intramedullary plate by periodic radiographs obtained preoperatively and at 4 weeks, 8 weeks, 3 months, and 6 months postoperatively. Correction of the hallux valgus angle averaged 17.8°, intermetatarsal angle 7.4°, distal metatarsal articular angle 2.7°, and sesamoid position 1.4 stages at 3 months postoperatively. The average lateral shift of the capital fragment was 6.5 mm. All patients achieved bone union, and there were no cases of dislocation, displacement, or avascular necrosis of the metatarsal head fragment. In conclusion, a distal Chevron osteotomy using an intramedullary plate was a favorable method for the correction of mild to moderate hallux valgus deformity. Levels of Evidence: Level IV: Case series.

Abstract
BACKGROUND: Third generation total talar prostheses (TTPs) are viable options for talar avascular necrosis (AVN) in the absence of neighboring joint pathology. The use of modern three-dimensional (3D) printing allows the production of custom implants that exactly mimic the patient's anatomy. The aim of this study is to determine the accuracy of 3D printing in reproducing a synthetic talus and, in doing so, restoring more normal anatomical relationships. We hypothesize that this mode of replication will restore and maintain normal radiographic alignment of the ankle, subtalar, and forefoot joints in the setting of talar AVN. METHODS: A retrospective analysis was performed on all patients undergoing TTP implantation for the treatment of talar AVN between 2016 and 2017. Radiographic measurements were taken preoperatively and postoperatively to determine native talar dimensions, TTP implant dimensions, and the corresponding radiographic alignment about the forefoot, hindfoot, and ankle. RESULTS: A total of 14 patients were identified in our cohort. Talar arc length and width were not found to be significantly changed; however, talar height was significantly increased with use of TTP. Five alignment dimensions were measured, of which, only talar tilt angle was significantly changed. Instances of Meary's angle correction were observed in cavus and planus foot deformity. CONCLUSION: As a proof of concept, 3D-printed TTP was successful in restoring talar height and talar tilt in the setting of AVN. Additionally, the procedure maintained normal alignment in nonpathological joints. TTPs, based on our cohort, are a viable option to restore more normal anatomical alignment.

Abstract
BACKGROUND: A number of new 2-component total ankle arthroplasty systems that emphasize minimal bone resection have been introduced for which few clinical outcomes reports are available. Our aim was to identify the rate of early revision among patients receiving the 2-component INFINITY prosthesis. METHODS: Patients from 2 prospectively collected databases at the authors' institution were screened for inclusion in the present study. All patients who underwent a primary total ankle arthroplasty (TAA) with the INFINITY prosthesis and who were at least 1 year postoperative were included. A total of 159 ankles with a mean 20 months of follow up (range, 12-37) met these criteria. All surgeries were performed by 1 of 2 orthopedic foot and ankle surgeons with extensive experience in TAA. The primary outcome was the need for revision surgery, defined as removal of 1 or both metal components. Peri-implant lucency at most recent follow-up was a secondary outcome. Weightbearing radiographs at most recent follow-up were graded for lucency independently by 2 reviewers. RESULTS: Sixteen ankles (10%) underwent revision at a mean 13 months postoperatively. The most common reasons for revision were symptomatic tibial component loosening and deep infection (6 patients each, 3.8%). Of the 108 ankles with retained components and at least 1 year of radiographic follow-up, 8 (7.4%) had global lucency around the tibial component suggestive of loosening at most recent follow-up. CONCLUSIONS: Our initial review of patients undergoing TAA with this new 2-component prosthesis demonstrates an elevated early revision rate due to tibial component loosening compared to other implant systems. LEVEL OF EVIDENCE: Level IV, case series.

Abstract
Outpatient total ankle arthroplasty is a potential significant source of cost savings. The ability to institute an effective outpatient total ankle program depends on appropriate patient selection, surgeon experience with total ankle replacement, addressing preoperative patient expectations, the involvement of an experienced multidisciplinary care team including experienced anesthesiologists, nurse navigators, recovery room nursing staff and physical therapists, and most importantly, such a program requires complete institutional logistical support.

Abstract
BACKGROUND Talar osteochondral lesions (OLT) occur frequently in ankle sprains and fractures. We hypothesize that matrix-induced autologous chondrocyte implantation (MACI) will have a low reoperation rate and high patient satisfaction rate in treating OLT less than 2.5cm2. METHODS A systematic review was registered with PROSPERO and performed with PRISMA guidelines using three publicly available free databases. Clinical outcome investigations reporting OLT outcomes with levels of evidence I-IV were eligible for inclusion. All study, subject, and surgical technique demographics were analyzed and compared. Statistics were calculated using Student's t-tests, one-way ANOVA, chi-squared, and two-proportion Z-tests. RESULTS Nineteen articles met our inclusion criteria, which resulted in a total of 343 patients. Six studies pertained to arthroscopic MACI, 8 to open MACI, and 5 studies to open periosteal ACI (PACI). All studies were Level IV evidence. Due to study quality, imprecise and sparse data, and potential for reporting bias, the quality of evidence is low. In comparison of open and arthroscopic MACI, we found both advantages favoring open MACI. However, open MACI had higher complication rates. CONCLUSIONS No procedure demonstrates superiority or inferiority between the combination of open or arthroscopic MACI and PACI in the management of OLT less than 2.5cm2. Ultimately, well-designed randomized trials are needed to address the limitation of the available literature and further our understanding of the optimal treatment options.
