ObjectivesThis study aimed to examine the content of the most-viewed pes planus exercise videos on YouTube^® and evaluate their quality and reliability.MethodsYouTube was searched with keywords "Pes planus exercises," "Pes planus rehabilitation," "Pes planus physiotherapy," "Flat foot exercises," "Flat foot rehabilitation," and "Flat foot physiotherapy." A total of 360 videos were independently reviewed by 2 evaluators. The URL of the videos, length, publication date, number of views/likes, number of comments, number of subscribers of the video source, video type, and exercise type of the videos were recorded. Video popularity view rate; quality and information content of videos, Global Quality Scale (GQS) and modified DISCERN scale; its reliability was evaluated with the Journal of the American Medical Association (JAMA) comparison score.ResultsOf the 49 videos that met inclusion criteria, 42.85% were of high quality according to GQS. Video length, number of comments, modified DISCERN, and JAMA scores were significantly higher in the high-quality group (P < .05). Other video features were not different (P > .05). The number of likes, comments, views, and subscribers of the videos, and video popularity, were positively correlated with each other at a moderate to high level (P < .001). High quality and reliability were significantly correlated only with longer video length and higher number of comments (P < .05).ConclusionThe overall quality of pes planus exercise videos on YouTube is low; however, longer videos with active viewer engagement tend to be of higher quality. This highlights the need for clinicians to direct patients to reliable digital resources and for content creators to follow standards.Level of Evidence:Level V: Systemic review of nonpeer-reviewed resources.

BackgroundThis study aims to investigate the validity of the Charlson Comorbidity Index (CCI) and Elixhauser Comorbidity Index (ECI) as predictive tools for adverse outcomes following total ankle arthroplasty (TAA).MethodsThe Nationwide Readmissions Database (NRD) was queried from 2015 to 2020 to identify 29 705 patients undergoing primary TAA. Patients' comorbidity was measured via CCI and ECI scores, and patients who experienced adverse postoperative outcomes (any complication, readmission, mortality, extended length of stay (LOS), and adverse discharge) were identified.ResultsBoth the ECI and CCI comorbidity indices predicted mortality with excellent accuracy (Area under the Curve [AUC] = 0.88 for both). However, ECI outperformed CCI in predicting complications, extended LOS, and adverse discharge, although both had poor predictive capability for these outcomes.ConclusionThese findings indicate that while ECI and CCI are capable of predicting postoperative mortality following TAA, there is a need for alternative models that better predict other postoperative adverse outcomes.Level of Evidence:Level III; Retrospective cohort study.

BackgroundSymptomatic progressive collapsing foot deformity (PCFD) is frequently treated with reconstructive surgery. Multiple studies have documented successful treatment based on improvements in symptoms and physical examination findings. However, it is not well-established whether there are corresponding improvements in gait function following surgical treatment for PCFD.MethodsA systematic review of biomechanical outcomes of treatments for flexible PCFD was conducted on PubMed. The 4 articles chosen involved patients with symptomatic flexible PCFD who underwent a reconstructive surgery. Surgical interventions included osteotomy, tendon transfer, and/or ligament repair or reconstruction. Primary outcomes involved objective quantifiable measurements of kinematic, kinetic, or temporospatial parameters.ResultsThe initial search yielded 605 articles, from which 26 were retained after screening the title and abstract. Twenty-two were eliminated yielding 4 articles. Temporospatial, kinematic, and kinetic parameters were all altered after the patients underwent surgical intervention. Specifically, stride length, cadence, and walking speed all improved postoperatively. Walking kinetics also improved with restoration of normal motion in the frontal and sagittal planes and improvements in the dorsiflexion angle. There were also improvements in sagittal power.DiscussionSurgical intervention to treat flexible PCFD improves objective biomechanical outcomes; however, more follow-up studies are needed to establish the reliability and durability of these improvements.Level of Evidence:Level III: Systematic review.

BackgroundThe aim of the study is to investigate the differences between the extensile lateral (EL) and sinus tarsi (ST) approaches for the treatment of displaced intra-articular calcaneus fractures as treated by a single surgeon.MethodsA retrospective cohort study performed at a Level 1 trauma center. One hundred twenty-nine consecutive intra-articular calcaneus fractures from 2011 to 2018 that were surgically treated by a single surgeon. Primary outcomes were time to surgery, operative time, postoperative restoration of the critical angle of Gissane, postoperative wound complications, and need for unplanned re-operation.ResultsPatient characteristics, including demographics, mechanism of injury, and fracture patterns were similar between the EL and ST approach groups. There was a significant decrease in unplanned secondary procedures (P = .008), shorter time to definitive fixation (P = .00001), and shorter average operative time in the ST group (P = .00001). Postoperative measurement of the critical angle of Gissane between the two groups was significantly different, but minute with an average difference of approximately 3 degrees (P = .025). Measurements in both groups were within the expected range of normal.ConclusionsFor displaced intra-articular calcaneus fractures, a limited open ST approach is associated with a significant reduction in the time to definitive fixation and decreased operative time. The EL approach was associated with a small, but significant improvement in the restoration of the critical angle of Gissane compared with the ST approach. Therefore, an ST approach may allow for earlier surgical intervention and result in equivalent quality of reduction compared with an EL approach.Level of Evidence:Level III.

Ankle fractures are a relatively common injury in the lower extremity. They can be treated with conservative management if they are nondisplaced and only involve the fibula. Nonunions at the fracture site, however, are a potential complicating factor during treatment. There is growing literature supporting the use of intramedullary fixation for fracture care. Not only does it have the advantages of using smaller incisions to preserve periosteum while providing improved biomechanical outcomes, but intramedullary reaming can help stimulate cells to promote bone healing. Few articles discuss the use and success of intramedullary reaming in revision surgery of the distal fibula. We present 3 cases of computed tomography-confirmed fibular nonunion following conservative fracture care, which underwent revision surgery with fibular nail fixation technique. These cases illustrate clinical and image findings as well as highlight the surgical technique used for each patient. At follow-up, all patients were asymptomatic and radiographs confirmed healing of the previous nonunion site. These cases are examples of successful revision for fibular fracture nonunion using intramedullary nail fixation.Level of Evidence: Level IV: Case series.

BackgroundFirst metatarsophalangeal (MTP) arthrodesis is a common surgical procedure for addressing hallux MTP pathology. In the setting of revision procedures with significant bone loss, porous titanium wedges may provide an alternative to structural bone autograft or allograft.ObjectiveThe purpose of this study is to report the clinical and radiographic outcomes achieved in first MTP interposition arthrodesis using porous titanium wedges.MethodsA retrospective analysis of 9 patients with a mean age 65.4 years (45-82 years) who underwent first MTP interposition arthrodesis with the use of porous titanium wedges from February 2014 to September 2017 was performed. Outcomes were assessed using both plain-film radiographs and computed tomography (CT) scans, as well as patient-reported outcome measures, including Foot and Ankle Ability Measure (FAAM) (Sports and Activities of Daily Living), pain Visual Analogue Scale (VAS), and 36-Item Short Form Survey (SF-36). Average follow-up time was 34.2 months (14-72 months).ResultsAt final follow-up, the average FAAM score was 91.1 ± 14.7 (75.1 ± 5.3 FAAM Activities of Daily Living; 17.9 ± 9.9 FAAM Sports). Average pain VAS score was 1.9 ± 1.7. Postoperative computed tomography (CT) imaging was obtained for 5 patients, all of which demonstrated good bony apposition or osseous integration of the wedge. Four patients underwent subsequent surgical procedures, including 3 isolated dorsal fixation revisions, and 1 complete MTP arthrodesis revision.ConclusionTo our knowledge, this study represents the first reported clinical and radiographic outcomes in patients undergoing first MTP interposition arthrodesis with use of porous titanium wedges. While we found this technique to be a viable alternative to bone grafting for this difficult problem, further research should focus on comparative data with other commonly performed operative techniques.Level of Evidence:Level IV: Case series.

IntroductionAvascular necrosis (AVN) of the talus is 1 of the most difficult foot and ankle pathologies to diagnose and manage. The purpose of this study was to report on the functional outcomes of 3D-printed total talus replacement (TTR) in 2 patients with talar AVN who both underwent a failed revascularization.MethodsThis is a case series of 2 patients with TTR after a failed revascularization and a comparison group of 25 patients with primary TTR. Clinical and functional outcomes are used to compare both groups.ResultsPatient 1 had a postrevascularization Visual Analogue Scale (VAS) pain score of 9. Imaging showed failure of the medial femoral condyle to incorporate with talar fragmentation. Patient underwent TTR at 5 months postoperatively. At 2 years postoperatively, the patient underwent a cavovarus foot reconstruction; however, patient continued to suffer from ankle pain (VAS 6) and ultimately underwent below knee amputation at 3 years after the TTR. Patient 2 initially underwent a core decompression for a talar bone infarct followed by revascularization procedure at 6 months postoperatively due to persistent pain and bony infarcts. At 18 months postrevascularization, the patient had a VAS pain score of 9 and progression of the AVN. She underwent a TTR. At 1-year follow-up, the VAS pain score was 8. Both patients had an ankle plantarflexion of 30° at their last TTR follow-up. The comparison group consisted of 25 patients who underwent 3D-printed TTR with mean postoperative VAS score and ankle plantarflexion of 3.7° and 41.8°.ConclusionPatients 1 and 2 demonstrated reduced plantarflexion and ankle motion after TTR relative to the comparison group which improved in both physical assessments. The first patient needed a below knee amputation for persistent pain. Patient 2 showed less improvement in all the foot and ankle outcome scores as compared with the primary TTR group.Level of Evidence:Level V: Retrospective case series.

BackgroundThis study investigates the effect of malnutrition, defined by hypoalbuminemia, on rates of complication, readmission, reoperation, and mortality following midfoot, hindfoot, or ankle fusion.MethodsThe National Surgical Quality Improvement Program (NSQIP) database was queried from 2005 to 2019 to identify 500 patients who underwent midfoot (n = 233), hindfoot (n = 261), or ankle (n = 117) fusion. Patients were stratified into normal (n = 452) or low (n = 48) albumin group, which was defined by preoperative serum albumin level <3.5 g/dL. Demographics, medical comorbidities, hospital length of stay (LOS), and 30-day complication, readmission, and reoperation rates were compared between groups. The mean age of the cohort was 58.7 (range, 21-89) years.ResultsHypoalbuminemia patients were significantly more likely to have diabetes (P < .001), be on dialysis (P < .001), and be functionally dependent (P < .001). The LOS was significantly greater among the low albumin group (P < .001). The hypoalbuminemia cohort also exhibited a significantly increased likelihood of superficial infection (P = .048). Readmission (P = .389) and reoperation (P = .611) rates did not differ between the groups.ConclusionThis study shows that malnourished patients have an increased risk of superficial infection following foot and ankle fusions but are not at an increased risk of readmission or reoperation, suggesting that low albumin confers an elevated risk of surgical site infection.Levels of Evidence:Level III, Retrospective cohort study.

BackgroundThe representation of sociodemographic data within randomized-controlled trials (RCT) regarding foot and ankle surgery is undefined. The purpose of this study was to determine the incidence of sociodemographic data being reported in contemporary foot and ankle RCTs.MethodsRandomized-controlled trials within the PubMed database from 2016 to 2021 were searched and the full text of 40 articles was reviewed to identify sociodemographic variables reported in the manuscript. Data regarding race, ethnicity, insurance status, income, work status, and education were collected.ResultsRace was reported in the results in 4 studies (10.0%), ethnicity in 1 (2.5%), insurance status in 0 (0%), income in 1 (2.5%), work status in 3 (7.5%) and education in 2 (5.0%). In any section other than the results, race was reported in 6 studies (15.0%), ethnicity in 1 (2.5%), insurance status in 3 (7.5%), income in 6 (15.0%), work status in 6 (15.0%), and education in 3 (7.5%). There was no difference in sociodemographic data by journal (P = .212), year of publication (P = .216), or outcome study (P = .604).ConclusionThe overall rate of sociodemographic data reported in foot and ankle RCTs is low. There was no difference in the reporting of sociodemographic data between journal, year of publication, or outcome study.Level of Evidence:Level II.

Critical sized bone defects in the ankle are becoming increasingly more common in patients undergoing limb reconstruction with tibiotalocalcaneal arthrodesis. Bulk allografts have not fared well over time. There have been scattered preliminary reports using custom spinal cages or 3D-printed Titanium Implants to address the critical bony defect; however, the cost of these devices is prohibitive in many clinical practice settings. The purpose of this investigation is to report the preliminary experience using a commercially available Trabecular Metal (Zimmer-Biomet) tibial metaphyseal cone combined with a retrograde locked intramedullary nail to address this challenging problem. Eight consecutive patients underwent tibiotalocalcaneal arthrodesis using a commercially available Trabecular Metal tibial metaphyseal cone combined with a retrograde locked intramedullary nail. Five developed bone loss secondary to neuropathic (Charcot) bony resorption and 3 underwent surgery for failed total ankle arthroplasty. All 8 patients eventually achieved clinical and radiographic healing and were able to ambulate with standard footwear. One patient developed a postoperative wound infection at the site of calcaneal locking screws, which resolved with debridement and parenteral antibiotic therapy. Critical bone defects about the ankle have successfully addressed with custom 3D titanium implants. This small series suggests that similar clinical outcomes can be achieved with the use of a commercially available porous tantalum metaphyseal spacer borrowed from our arthroplasty colleagues, combined with the use of a retrograde locked intramedullary nail.Levels of Evidence: Level 4: Retrospective case series.
