RESUMEN

BACKGROUND: Collapse of the talus and peri-talar arthritis pose treatment challenges due to the anatomy and location of the talus as a keystone of the foot and ankle. Custom 3D-printed total talus replacement (TTR) and combined total ankle total talus replacement (TATTR) have emerged as treatment options for these pathologies. However, the safety and efficacy of these implants is unknown due to the limited number of cases and short follow-up durations. METHODS: This was a retrospective study to assess surgical outcomes of patients who underwent a TTR and TATTR with or without subtalar fusion. Patient demographics, intraoperative parameters, device related surgical and non-surgical events, imaging and clinical evaluations, and patient reported outcome (PRO) measures were compiled. RESULTS: A total of 38 patients received a custom 3D-printed implant with mean follow-up time of 22.1 (range: 12-45) months. In this cohort, 7 (18.4 %) required secondary surgery and 3 (7.9 %) required implant removal. Multivariate logistic regression revealed that patient diagnosis of depression was a significant predictor of secondary surgery with an OR 17.50 (p = 0.037). Significant postoperative improvements were observed in the talocalcaneal height (p = 0.005) and talar declination angle (p = 0.013) for the TATTR group. VAS and PROMIS pain interference (PI) scores demonstrated an initial significant improvement in pain, but this improvement did not maintain significance at most recent follow-up. However, there was a significant increase in the PROMIS physical function (PF) scores (p = 0.037) at most recent follow-up. CONCLUSION: These results demonstrate that TTR and TATTR provide significant improvement in post-operative radiographic foot and ankle alignment and physical function at the two-year timepoint. PRO findings suggest that patients are more active after surgery. Surgeons considering proceeding with either of these procedures should counsel patients about pain and functional outcomes as well as realistic expectations in patients with depression. LEVEL OF EVIDENCE: Level 3.

RESUMEN

BACKGROUND: The recent addition of biceps tendon augmentation to partial arthroscopic rotator cuff repair (ARCR) for the treatment of large-to-massive rotator cuff tears is proposed to improve clinical outcomes and reduce re-tears. MATERIALS AND METHODS: The purpose of this systematic review and meta-analysis (5 studies) was to compare outcomes between partial ARCR with (142 patients) and without (149 patients) biceps augmentation. RESULTS: Partial ARCR with and without biceps augmentation were comparable in pain, function, and range of motion. However, biceps augmentation vs no augmentation at all during ARCR may lower re-tear rates for irreparable large-to-massive rotator cuff tears (42.9% vs 72.5%, P=.007). CONCLUSION: More research is needed to investigate this technique and guide surgical decision-making. [Orthopedics. 20XX;4X(X):XXXXXX.].

RESUMEN

BACKGROUND: Telemedicine has seen increasing adoption in healthcare over the past two decades, with proven clinical efficacy in several medical specialties. Orthopedics surgery has shown potential benefits from telemedicine implementation. OBJECTIVE: This review aims to evaluate the impact of telemedicine on clinical outcomes and patient and physician preferences in foot and ankle orthopedics, providing insight into the potential role of telemedicine within this subspecialty. METHODS: Multiple databases were searched for relevant articles on telemedicine in foot and ankle orthopedics. Inclusion criteria encompassed articles on telemedicine use and foot and ankle orthopedic care. Data included patient demographics, reasons for visits, duration of telemedicine, and outcomes. Analysis involved descriptive statistics, and a narrative approach to describe outcomes. RESULTS: Out of 218 articles, 12 met the inclusion criteria, comprising a total of 1,535 patients. Telemedicine visits were used for follow-up care, opinion consultations, monitoring, postoperative care, and treatment of various orthopedic conditions. Clinical outcomes demonstrated equivalence to in-person care. Patients expressed satisfaction with telemedicine but preferred in-person visits for future appointments. Physicians held neutral attitudes towards telemedicine, with concerns about the lack of physical examination. CONCLUSION: This review highlights the benefits of telemedicine in foot and ankle orthopedics. Telemedicine provides an alternative to in-person visits, improving patient access to care and offering cost and time savings. However, patient and physician preferences for in-person visits suggest a need to address concerns related to physical examination limitations. Telemedicine can supplement traditional care, but further research is required to explore its applicability in new patient consultations and optimize physician engagement.

RESUMEN

INTRODUCTION: Launched in 2018 for revision total ankle arthroplasty (rTAA), the INVISION talar component addresses subsidence when poor talar bone stock is present. Due to the recency of the market-availability of the INVISION, studies evaluating its efficacy are lacking. This study presents the first analysis of early-term outcomes of patients undergoing rTAA with the INVISION talar component. METHODS: This was a single-center, retrospective review of 28 patients undergoing rTAA with the INVISION talar component and INBONE II tibial component performed between 2018 and 2022. Data on preoperative characteristics, postoperative complications, secondary procedures, and survivorship were collected. The primary outcome measures were rates of major complications, re-operation, and implant failure. Secondary outcomes included post-operative changes in varus and valgus alignment of the tibia and talus. RESULTS: The most common secondary procedures performed with rTAA were medial malleolus fixation (n = 22, 78.6%) and gastrocnemius recession (n = 14, 50%). Overall, 10.7% (n = 3) of patients underwent reoperation and 14.3% (n = 4) suffered major complications. Incidence of implant failure was 10.7% (n = 3). All reoperations were caused by infection. Mean varus alignment of the tibia and talus improved from 4.07 degrees and 4.83 degrees to 1.67 degrees and 1.23 degrees, respectively. Mean valgus alignment of the tibia and talus improved from 3.67 degrees and 4.22 degrees to 2.00 degrees and 2.32 degrees, respectively. CONCLUSIONS: In a series of 28 patients undergoing rTAA with the INVISION talar component, we discovered comparatively low rates of reoperation, major complication, and implant failure (10.7%, 14.3%, and 10.7%). The INVISION system appears to have a reasonable safety profile, but further studies evaluating long-term outcomes are required to assess the efficacy of the INVISION system.

RESUMEN

STUDY DESIGN: Retrospective Analysis. OBJECTIVE: The objective of the study was to assess the impact of academic productivity at both individual and program levels on lifetime industry earnings within US orthopedic spine fellowships. SUMMARY OF BACKGROUND DATA: Physician-industry transparency was codified by the Physician Payments Sunshine Act (PSSA) in 2010. No study has explored the relationship between academic productivity and industry earnings at the fellowship level. METHODS: Inclusion criteria encompassed physicians with complete academic and industry data from orthopedic spine fellowship programs listed on the North American Spine Society (NASS) 2022-2023 fellowship directory. Academic productivity was defined via H-index on the Scopus website, and industry productivity by total lifetime earnings on the Open Payments Database (OPD). RESULTS: This analysis included 75 orthopedic spine fellowship programs with 320 individual physicians. Median individual physician lifetime earnings were $86,852.71 (mean: $666,580.23 ± $1,887,734.64; minimum-maximum: $10.86-$27,164,431.49) and the median individual physician (n=320 physicians) H-index was 17.0 (mean: 21.82 ± 19.28; minimum-maximum: 0-109). Median combined physician H-index per fellowship (n=75 fellowships) was 65.0 (mean: 93.08 ± 85.67; minimum-maximum: 3-434) and median combined physician lifetime earnings was $927,771.60 (mean: $2,844,075.64 ± $4,942,089.56; minimum-maximum: $1,112.32-$29,983,900.69). A positive correlation was observed between academic productivity and industry productivity at an individual level (P<0.001; Spearman's rho = 0.467). This correlation was stronger at the fellowship level (P<0.001; Spearman's rho = 0.734). There was no significant difference in total lifetime earnings (P=0.369) or H-index per fellowship (P=0.232) when stratified by region of the fellowship program in the United States. CONCLUSION: Orthopedic spine surgery fellowship programs in the United States exhibit a positive correlation between academic productivity and nonresearch industry lifetime earnings at both individual and program levels. This correlation is stronger at the program level, and regional differences among fellowship programs do not significantly impact academic or industry productivity.

RESUMEN

This systematic review and meta-analysis delved into the impact of race and ethnicity on outcomes following foot and ankle surgery, an area garnering increasing attention within the medical community. Despite significant literature on postsurgical clinical and functional outcomes, limited research has explored the influence of racial and ethnic factors on postoperative outcomes. In this study, data from 33 relevant studies, involving a total of 557,734 patients, were analyzed to assess outcomes across different racial and ethnic groups. Notably, only 6 studies met the criteria for inclusion in the final meta-analysis due to variations in outcome reporting. Findings revealed disparities in functional scores, pain levels, and resource utilization among different racial and ethnic cohorts. Specifically, non-White and minority patients exhibited higher rates of foot and ankle fractures and lower extremity surgeries, worse functional outcomes, increased pain, longer hospital stays, and a greater incidence of complications compared to their White counterparts. However, some studies presented contradictory results, emphasizing the necessity for further investigation to elucidate these discrepancies fully. This research underscores the importance of considering racial and ethnic factors in foot and ankle surgery outcomes and highlights the need for targeted interventions to address existing disparities.

RESUMEN

INTRODUCTION: Physician-review websites (PRWs) are commonly used by patients while searching for a surgeon. There is no current literature investigating the factors that contribute to online one-star reviews of musculoskeletal oncology surgeons. This retrospective study aims to identify these factors to determine areas of care affecting patient's subjective reviews. METHODS: Patient ratings and comments regarding musculoskeletal oncology surgeons from the Musculoskeletal Tumor Society (MSTS) were collected from Vitals.com. One-star reviews with comments were then classified as either operative or nonoperative. These complaints were then further classified based on content including wait time, uncontrolled pain, time spent with the physician, surgical outcomes, medical staff/institutional complaints, and bedside manner. RESULTS: A total of 169 reviews (375 complaints) from 181 physicians were included. Of these complaints, 198 were from patients in the operative category while 177 were from patients in the nonoperative category. Bedside manner was the most common complaint. Operative patients reported higher instances of uncontrolled pain in their reviews, whereas nonoperative patients more frequently cited wait time. No significant difference in the complaints that mentioned the amount of time spent with the physician, bedside manner, a disagreement with the plan, or the medical staff or institution was found. CONCLUSION: Online one-star reviews of musculoskeletal oncology surgeons on Vitals.com referenced both surgical and non-surgical aspects of patient encounters, with bedside manner being the most popular complaint overall. Surgical patients were more likely to complain of uncontrolled pain whereas non-operative patients were more likely to complain of wait time. TYPE OF STUDY: Outcomes 2c.

RESUMEN

Interpositional arthroplasty for the treatment of hallux rigidus (HR) involves resection of the diseased joint surface and placement of spacer material within the joint to preserve length at the metatarsophalangeal joint while still allowing for range of motion. The majority of studies available in the literature have focused on capsular interpositional arthroplasty, revealing generally positive outcomes. Other forms of interpositional arthroplasty are less supported by long-term follow-up and large sample sizes. Moreover, there exists substantial heterogeneity in the studies evaluating interpositional arthroplasty. Despite the limitations of the current data, interpositional arthroplasty seems to be a viable treatment option for HR.

RESUMEN

The differences in complication rates between the direct anterior and posterior approaches for hemiarthroplasty in elderly patients with femoral neck fractures are not yet fully understood. Dislocation, a severe complication associated with increased mortality and often requiring additional surgery, may occur less frequently with the direct anterior approach compared to the posterior approach. Careful consideration of patient demographics is essential when planning the surgical approach. Future research in this area should focus on robust randomized controlled trials involving elderly patients recovering from femoral neck fractures.

RESUMEN

This article describes the etiology, clinical presentation, surgical management, and outcomes for treatment of the failed first metatarsophalangeal (MTP) joint arthroplasty. Failure following implant arthroplasty typically creates large osseous deficits and surgical management can be difficult. Salvage arthrodesis provides reliable joint stability while maintaining hallux length. Outcomes following conversion of a failed MTP joint arthroplasty to MTP joint arthrodesis have demonstrated consistent pain relief and high satisfaction: however, high rates of complication and nonunion have been reported. Bone graft may be necessary to fill large voids in the joint. Other revision options for failed arthroplasty have been described, but outcomes remain inconsistent and varied. Ultimately, conversion to MTP joint arthrodesis is the recommended intervention for treatment of the failed MTP arthroplasty implant, providing sufficient stability and pain relief.

RESUMEN

Osteochondral lesions of the talus are common injuries that are most often the result of trauma. The natural progression of osteochondral lesions is not well understood. It is still unclear which lesions eventually lead to joint degeneration and osteoarthritic changes and if the treatment method affects the progression. The existing literature surrounding this topic is sparse, with inconsistent findings. The presented images are taken from a 72-year-old man with bilateral osteochondral lesions of the talus. To our knowledge, this is the first published series of images illustrating the natural progression of a patient with bilateral osteochondral lesions of the talus over a 12-year time period.

RESUMEN

Ankle osteoarthritis (OA) is less common than knee and hip OA, and 75% to 80% of all presentations are posttraumatic in nature, resulting from either ligamentous or bony injury to the ankle. While the ankle joint cartilage demonstrates capacity for self-restoration, the ankle joint is sensitive to aberrancies in biomechanics and the inflammatory milieu after an injury is thought to contribute to the onset of posttraumatic ankle OA. Conservative care for ankle OA is currently centered on pain reduction, and derivatives that may delay the progression of ankle OA are the subject of ongoing investigation. Surgical management for end-stage ankle OA currently focuses on ankle arthrodesis and total ankle arthroplasty. Specific indication for one procedure over the other is the topic of much debate. While total ankle arthroplasty has become more frequently used with the advent of newer generation systems, ankle arthrodesis may still be favored in younger patients with high-demand occupations.

RESUMEN

Smoking is a well-known cause of impairment in wound healing and postoperative outcomes; however, its effects on treating meniscus issues remain unclear. This study assesses the relationship between smoking and meniscus treatment outcomes. PubMed, Scopus, Cochrane, and CINAHL were searched from inception to 24 December 2023. Inclusion criteria encompassed studies examining smoking's impact on patient outcomes regarding meniscus pathology. A secondary PubMed search targeted randomized controlled trials (RCTs) in the top ten orthopedic journals focusing on meniscus pathology and smoking as a demographic variable. Meta-analysis of six studies (n = 528) assessed meniscus failure rate based on smoking status. Eighteen observational studies (n = 8353 patients; 53.25% male; mean age: 51.35 ± 11.53 years; follow-up: 184.11 ± 117.34 months) were analyzed, covering meniscus repair, meniscectomy, allograft transplant, conservative care, and arthroscopy. Results showed four studies (36.36%) linked smoking with worse meniscus repair outcomes, while seven studies (63.64%) did not find significant associations. Meta-analysis from six studies showed no significant impact of smoking on repair failure (p = 0.118). Regarding meniscectomy, one study (33.33%) identified a significant association with smoking, but two did not. Only one (3.8%) of the RCTs in leading orthopedic journals included smoking as a factor. The evidence on smoking's effect on meniscus treatment is mixed, necessitating further investigation.

RESUMEN

Background Hallux rigidus (HR) is the most common arthritic condition of the foot. Although first metatarsophalangeal joint (MTPJ) arthrodesis has been the historical gold-standard treatment, polyvinyl alcohol (PVA) hydrogel implants have gained popularity as a joint-sparing technique. However, recent studies have shown variable failure rates of PVA hydrogel implants. The purpose of this study was to report the five-year experience with PVA hydrogel implants performed by a single surgeon. Methodology Health records were queried from August 2016 to 2021 for patients who underwent primary PVA hydrogel implant hemiarthroplasty for symptomatic late-stage HR. Patient demographics and postoperative outcomes variables were evaluated. Kaplan-Meier analysis was used to evaluate implant survival. A total of 146 PVA hydrogel implant procedures were performed with a minimum six-month follow-up. Results The majority of patients were female (n = 103, 70.5%), with a mean age of 58.1 (±10.1) years, body mass index of 27.3 (±5.2) kg/m2, and American Society of Anesthesiologists score <3 (n = 131, 89.7%). The majority had stage II or III disease (n = 115, 78.8%). Patients experienced significant improvement in visual analog scale score (p < 0.0001) and hallux dorsiflexion (p = 0.0005). There were 22 (15.1%) complications, including implant subsidence (n = 15, 10.3%), deep infection (n = 6, 4.1%), and hypertrophic ossification (n = 1, 0.7%). Revision surgeries were required in 12.3% (n = 18) of patients at an average of 9.4 (±9.2) months postoperatively. This included nine (6.2%) revision PVA hydrogel implant procedures and nine (6.2%) first MTJP arthrodesis. The one- and two-year survival rates for MTPJ arthrodesis (n = 9) were 95.9% and 86.3%, respectively. Conclusions In the largest single-surgeon series reported, first MTPJ hemiarthroplasty with a PVA hydrogel implant significantly improved pain and hallux dorsiflexion at an average of 14.5 months postoperatively. There was a high two-year survivorship of 86.3% until failure which required first MTPJ arthrodesis. Future studies should be performed to refine the indications for PVA hydrogel implants and identify risk factors.

RESUMEN

Background: Arthroscopic-assisted treatment of ankle fractures has proven useful in the adult population, but little evidence exists for the utilization of arthroscopic-assisted ankle fracture fixation in the pediatric population. The purpose of this systematic review is to examine the management of pediatric ankle fractures using arthroscopy. Methods: A systematic review was performed using PubMed, Web of Science, CINAHL, and MEDLINE from database inception to February 22nd, 2023. Inclusion criteria for this systematic review was pediatric population less than age 18, arthroscopic surgery management, and ankle fracture. Results: A total of 19 articles (n=30 patients) out of 176 articles met final inclusion criteria with all articles consisting of case reports or case series. The average patient age was 13.8±1.6 years. Sixteen of the patients (53%) had arthroscopic surgery along with an adjunct surgery as indicated, whereas 14 patients (47%) had arthroscopic surgery with or without percutaneous fixation. A high majority of patients demonstrated full range-of-motion and large improvements in function. Conclusions: Arthroscopy is used with percutaneous fixation or in adjunct to open approaches for pediatric ankle fracture management with good results. More research is needed to determine the utility of arthroscopy in the management of pediatric ankle fractures.

RESUMEN

Background: The incidence of primary total ankle arthroplasty (TAA) is rising, with a corresponding increase in revision surgeries. Despite this, research on risk factors for revision TAA following primary TAA remains limited. Radiographic soft tissue thickness has been explored as a potential predictor for outcomes in hip, knee, and shoulder arthroplasty, but its role in TAA has not been assessed. This study aimed to assess the predictive value of radiographic soft tissue thickness for identifying patients at risk of requiring revision surgery following primary TAA. Methods: A retrospective study was conducted on 323 patients who underwent primary TAA between 2003 and 2019. Radiographic measurements of soft tissue thickness were obtained from preoperative radiographs. Two novel radiographic measures of soft tissue thickness were developed and assessed (tibial tissue thickness and talus tissue thickness). Clinical variables including age, gender, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, diabetes, smoking status, primary diagnosis, and implant type were recorded. Logistic regression analysis was used to assess the predictive value of soft tissue thickness and BMI for revision TAA. Results: The rate of revision surgery was 4.3% (14 of 323 patients). Patients requiring revision had significantly greater tibial tissue (3.54 vs 2.48 cm; P = .02) and talus tissue (2.79 vs 2.42 cm; P = .02) thickness compared with those not requiring revision. Both the tibial tissue thickness (odds ratio 1.16 [1.12-1.20]; P < .01) and the talus tissue thickness (odds ratio: 1.10 [1.05-1.15]; P < .01) measurements were significant predictors of revision TAA in multivariable logistic regression models. However, BMI was not a significant predictor of revision TAA. The two metrics demonstrated excellent interrater reliability. Conclusion: Greater soft tissue thickness was a better predictor of revision TAA compared with BMI. These findings suggest that radiographic soft tissue thickness may be a valuable tool for assessing the risk of the need for revision TAA following primary TAA. Further research is needed to validate and explore the potential impact on clinical practice. Level of Evidence: Level III, comparative study.

RESUMEN

Background During the COVID-19 pandemic, Americans transitioned away from their normal routines, drove in motor vehicles less, and reduced their physical activity, ultimately influencing the incidence and nature of orthopedic injuries that were operatively managed. The purpose of this study was to evaluate the effect of the COVID-19 pandemic lockdown and subsequent deconditioning on the mechanism of injury and severity of Lisfranc injury. Methods This retrospective study included patients with a traumatic Lisfranc injury who were surgically treated by a foot and ankle fellowship-trained orthopedic surgeon between 2015 and 2021. Electronic health records were queried for patient demographics, mechanism of injury, physical exam findings, and pain scores. Preoperative radiographs were reviewed to grade Lisfranc injuries using the previously described Nunley-Vertullo classification system. Descriptive and univariate statistics were performed to compare 15 patients in the pre-COVID-19 cohort and 15 patients in the post-COVID-19 cohort. Results In the pre-COVID-19 cohort, 80% (n=12/15) of the patients were female, the mean age was 46±15 years, the mean BMI was 29.7±7 kg/m2, and the mean follow-up period was 18.1±12 months. In the post-COVID-19 cohort, 53% (n=8/15) of the patients were female, the mean age was 48.5±17 years, the mean BMI was 31.4±7 kg/m2, and the mean follow-up period was 9.5±4 months. Significantly higher proportions of plantar ecchymosis (n=8/15, 53%), neuropathic pain (n=7/15, 47%), and swelling (n=12/15, 80%) were present in the post-COVID-19 cohort. A low-energy mechanism of injury was sustained by 73% (n=11/15) of the pre-COVID-19 cohort and 80% (n=12/15) of the post-COVID-19 cohort. Lisfranc injuries for the pre-COVID-19 cohort and the post-COVID-19 cohort demonstrated the following classifications: Grade 1 (33%, n=5/15 vs. 40%, n=6/15), Grade 2 (60%, n=9/15 vs. 53%, n=8/15), and Grade 3 (7%, n=1/15 vs. 7%, n=1/15). Conclusion Although a higher proportion of plantar ecchymosis, neuropathic pain, and swelling was observed, there was no association between a low mechanism of injury and a higher grade of Lisfranc injury following the COVID-19 pandemic.

RESUMEN

The last several decades have brought about substantial development in our understanding of the biomolecular pathways associated with chondral disease and progression to arthritis. Within domains relevant to foot and ankle, genetic modification of stem cells, augmentation of bone marrow stimulation techniques, and improvement on existing scaffolds for delivery of orthobiologic agents hold promise in improving treatment of chondral injuries. This review summarizes novel developments in the understanding of the molecular pathways underlying chondral damage and some of the recent advancements within related therapeutics.

RESUMEN

Cartilage damage presents a significant clinical challenge due to its intrinsic avascular nature which limits self-repair. Addressing this, our study focuses on an alginate-based bioink, integrating human articular cartilage, for cartilage tissue engineering. This novel bioink was formulated by encapsulating C20A4 human articular chondrocytes in sodium alginate, polyvinyl alcohol, gum arabic, and cartilage extracellular matrix powder sourced from allograft femoral condyle shavings. Using a 3D bioprinter, constructs were biofabricated and cross-linked, followed by culture in standard medium. Evaluations were conducted on cellular viability and gene expression at various stages. Results indicated that the printed constructs maintained a porous structure conducive to cell growth. Cellular viability was 87% post printing, which decreased to 76% after seven days, and significantly recovered to 86% by day 14. There was also a notable upregulation of chondrogenic genes, COL2A1 (p = 0.008) and SOX9 (p = 0.021), suggesting an enhancement in cartilage formation. This study concludes that the innovative bioink shows promise for cartilage regeneration, demonstrating substantial viability and gene expression conducive to repair and suggesting its potential for future therapeutic applications in cartilage repair.
