Abstract
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.

Abstract
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.

Abstract
Patients with bilateral ankle arthritis have higher rates of primary and secondary/inflammatory arthritis and a more debilitating condition than those with unilateral pathology. The limited bilateral total ankle arthroplasty (TAA) literature supports both 1-surgeon and 2-surgeon team bilateral TAAs as safe and effective with comparable improvements in patient-reported outcome measures (PROMs), complications, reoperations, and prosthesis survival as unilateral TAA and staged bilateral TAA. Additional benefits of bilateral arthroplasty supported in the hip and knee literature include cost reduction, noninferior and even superior perioperative complication profiles, improved PROM and satisfaction, shorter recovery time, early rehabilitation, and less time away from employment.

Abstract
BACKGROUND Nonunion rates following ulnar shortening osteotomy (USO) are reported up to 18% with few known risk factors. While resection length is variable in practice, little is known about the prognostic implications on healing. The purpose of this study was to evaluate whether longer resection lengths increased the odds of nonunion. METHODS A retrospective review was performed on patients who underwent an elective USO at a single institution over a 6-year period. Demographic, social, comorbidity, and surgical data were reviewed. Ulnar resection length was obtained from operative notes and dichotomized into smaller (<5.5 mm) and larger (≥5.5 mm) groups. The primary outcome was the rate of nonunion. Univariate analyses and a multivariable logistic regression model were used to assess for significant predictors of nonunion. RESULTS A total of 87 patients were included with a mean age of 45 years. Patient comorbidities included 12.6% with diabetes, 29.9% with an American Society of Anesthesiologists score of ≥ 3, 5.8% reporting current tobacco use, and 29.9% reporting former tobacco use. There were 55 patients (63.2%) with resection lengths < 5.5 mm and 32 patients (36.8%) with ≥ 5.5 mm resections. Multivariable analysis identified longer resection length (≥5.5 mm) and current tobacco use as independent risk factors for nonunion. Patients with a resection length of ≥ 5.5 mm had 20.2 times greater odds of nonunion compared with patients with smaller resections, and current smokers had 72.2 times greater odds of nonunion compared with nonsmokers. CONCLUSION Longer ulnar resection length (≥5.5 mm) significantly increases the risk of nonunion following USO.

Abstract
BACKGROUND The effect of tibiotalar joint line level (TTJL) on patient outcomes following total ankle arthroplasty (TAA) remains unclear. It was previously reported that patients with end-stage ankle arthritis have an elevated TTJL compared with nonarthritic ankles, and the TTJL post-TAA remains elevated compared with nonarthritic ankles. The objectives of this study were to (1) propose a reliable radiographic method to measure the TTJL absolute value and (2) determine the effect of TTJL alterations on tibiotalar range of motion (ROM) following TAA. METHODS A retrospective review was performed on patients who underwent TAA between January 2018 and April 2021 with a minimum of 1-year postoperative follow-up and complete perioperative ROM radiographs. Radiographic TTJL and ROM measurements were performed by 2 observers. The proposed TTJL measuring technique computes 4 measurements: high, low, center of the talus (center), and center of the axis (axis). Reliability of measurements and correlation between TTJL measurements and ROM were assessed. RESULTS A total of 33 patients were included. Postoperatively, 22 patients had a lowered TTJL compared to 11 patients with an elevated TTJL (2.2 ± 1.3 mm lowered vs 1.9 ± 1.2 mm elevated; P < .0001). Of the 4 TTJL measurements, 3 (low, center, axis) demonstrated a significant positive correlation between lowering the TTJL and improved tibiotalar dorsiflexion and 2 (low, axis) for total ROM (all P < .05). Plantarflexion was not significantly affected by TTJL alterations. Compared to patients with an elevated TTJL, patients with a lowered TTJL had improved tibiotalar dorsiflexion (8.8 vs 2.5 degrees; P = .0015) and total ROM (31.0 vs 22.9 degrees; P = .0191), respectively. The interrater reliability was nearly perfect (intraclass correlation r = 0.96-0.99). CONCLUSION In this small series, we found that lowering the TTJL level may more closely reestablish the native TTJL and correlates with improved tibiotalar dorsiflexion and total ROM following TAA.

Regional anesthesia is associated with improved metastasis free survival after surgical resection of bone sarcomas. J Orthop Res 2023; 41:2721-2729. [PMID: 37151123 PMCID: PMC10630530 DOI: 10.1002/jor.25597] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 04/13/2023] [Accepted: 05/03/2023] [Indexed: 05/09/2023]
Abstract
There is increasing evidence that perioperative factors, including type of anesthesia, may be an important consideration regarding oncological disease progression. Previous studies have suggested that regional anesthesia can improve oncological outcomes by reducing the surgical stress response that occurs during tumor resection surgery and that may promote metastatic progression. The purpose of this study is to provide the first robust investigation of the impact of adding regional anesthesia to general anesthesia on oncological outcomes following sarcoma resection. One hundred patients with bone sarcoma were retrospectively analyzed in this study. After adjusting for confounding variables such as age and grade of the tumor, patients with bone sarcoma receiving regional anesthesia in addition to general anesthesia during resection had improved metastasis free survival (multivariate hazard ratio of 0.47 and p = 0.034). Future studies are needed to confer the beneficial effect of regional anesthesia, and to further investigate the potential mechanism. Clinical significance: The results from this study provide evidence that regional anesthesia may be advantageous in the setting of bone sarcoma resection surgery, reducing pain while also improving oncological outcomes and should be considered when clinically appropriate.

Short-Term Outcomes of Jones-Specific Implant Versus Intramedullary Screw and Plate Fixation for Proximal Fifth Metatarsal Fractures. J Foot Ankle Surg 2023; 62:862-867. [PMID: 37211269 DOI: 10.1053/j.jfas.2023.05.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2023] [Revised: 04/24/2023] [Accepted: 05/13/2023] [Indexed: 05/23/2023]
Abstract
Although intramedullary screw fixation is commonly performed for proximal fifth metatarsal fractures, high rates of nonunion, refracture, and hardware prominence have been reported. The Jones Specific Implant (JSI) is a novel surgical implant which contours to the native curvature of the fifth metatarsal allowing for a more anatomic fixation. The purpose of this study was to compare short-term complication rates and outcomes of patients treated with the JSI to other fixation types such as plates and intramedullary screws. Electronic records were queried for adult patients with proximal fifth metatarsal fractures who underwent primary fixation from 2010 to 2021. All patients were treated by a foot and ankle fellowship-trained surgeon with intramedullary screws, plates, or JSI (Arthrex Inc., Naples, FL). Visual analog scale (VAS) and the American Orthopedic Foot and Ankle Score (AOFAS) were recorded and compared using univariate statistics. Eighty-five patients underwent fixation using intramedullary screw (n = 51, 60%), plate (n = 22, 25.9%), or JSI (n = 12, 14.1%) with a mean follow-up of 11.1 ± 14.6 months. The total cohort demonstrated a significant improvement in VAS pain (p < .0001) as well as AOFAS (p < .0001) scores. When comparing the cohort treated with JSI and the cohort treated with all other types of fixation, there were no significant differences in postoperative VAS or AOFAS scores. Only 3 complications, one with JSI (3.5%) required removal of the symptomatic hardware. The JSI is a novel treatment for proximal fifth metatarsal fractures, with similar early outcomes and complication rates when compared with intramedullary screw and plate fixation.

Abstract
Hallux valgus is a common progressive forefoot deformity. Although open techniques have shown good outcomes, no technique has been shown to be superior to other techniques. The current third generation of minimally invasive Chevron-Akin (MICA) technique features a percutaneous procedure with a stable internal fixation. The technique used in this study resulted in stable internal fixation; however, 1 screw was used in intramedullary fashion in the majority of cases. The purpose of this study is to review the early outcomes of MICA. Electronic Health Records (EHR) were queried for patients who underwent MICA to treat hallux valgus (HV) deformity, by a single surgeon. The primary clinical outcomes assessed were visual analog pain score (VAS), rate of revision surgery, and recurrence. Radiographic outcomes were assessed including pre and postoperative hallux valgus angle (HVA), intermetatarsal angle (IMA), and bony foot width. The secondary outcomes included postoperative complications. A total of 91 feet underwent MICA to correct symptomatic HV deformity. The mean age of this cohort was 53.63 ± 15.42 years, mean body mass index (BMI) of 26.81 ± 6.21 kg/m2, mean follow-up of 6.33 ± 6.39 months and 87 feet belonged to female patients. Patients showed significant improvement in VAS and radiographic outcomes at final follow-up, with a mean improvement of 10.70° ± 6.42°, 2.39° ± 3.55°, and 5.30 mm ± 4.23 mm for the HVA, IMA, and bony foot width, respectively. Two patients (2.2%) required revision surgery for nonunion and removal of symptomatic hardware. One patient had a second metatarsal fracture treated nonoperatively. No feet had recurrence, hardware loosening, infection, or scar hypersensitivity. The current study reported on early outcomes for MICA. This technique appears to be effective and safe with no failure of fixation in our patients. We showed in our short-term follow-up, MICA led to significant improvement in pain and radiographic scores.Levels of Evidence: III, retrospective study.

Abstract
BACKGROUND While metatarsophalangeal joint (MTPJ) arthrodesis is regarded as the gold standard treatment option for end-stage hallux rigidus (HR), synthetic cartilage implant (SCI) resurfacing has gained popularity. This study aimed to identify the SCI resurfacing failure rate for a single surgeon, while also comparing clinical outcomes of patients who underwent SCI replacement or MTPJ arthrodesis after failed index SCI resurfacing. METHODS Health records were queried from 2016 to 2021 for patients with HR who were treated with SCI resurfacing by a single surgeon. Preoperative and postoperative range of motion, visual analog scale (VAS) pain scores, and hallux valgus angles were compared. A subgroup analysis was performed on patients who underwent revision with SCI replacement or MTPJ arthrodesis. SCI replacement included the use of bone graft, bone putty, or a custom 3D printed baseplate to prevent implant subsidence. RESULTS A total of 219 SCI resurfacing procedures were performed by a single surgeon, including 23 revisions. When analyzing index procedures, an 8.2% revision rate was determined. The revision cohort (n = 23) consisted of 19 female patients and presented with a mean body mass index of 29.5 ± 5 kg/m2, mean age of 52.8 ± 11 years, mean follow-up duration of 22.3 (range, 3-54) months, and mean time to a revision surgery of 12.1 ± 12 (range, 1-50) months. Specifically, 12 procedures resulted in an SCI replacement, while 11 procedures resulted in arthrodesis. While all patients experienced significant improvement in their VAS pain scores (P < .001), the arthrodesis cohort experienced a greater improvement than the SCI revision cohort (P = .04). CONCLUSION When analyzing SCI revision procedures, MTPJ arthrodesis reduced pain more significantly than SCI replacement. LEVELS OF EVIDENCE Level IV: Retrospective case series.

Abstract
The purpose of this review is to develop evidence-based practices for the use of platelet-rich plasma (PRP) to treat osseous pathologies of the lower extremity. There is moderate high-quality evidence to support the efficacy of PRP as a surgical augment to microfracture in osteochondral lesions of the talus (OLT). The literature supports a conceivable positive impact on bony union and osseous healing. There is insufficient evidence to support PRP injections in the conservative management of OLT or symptomatic ankle osteoarthritis. PRP may serve as a viable treatment method in the surgical augmentation of microfracture surgery in OLT and has promise for increasing bony union following surgical operations. Further high-quality, comparative studies with longer clinical follow-up are required.

Abstract
INTRODUCTION Avascular 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. METHODS This 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. RESULTS Patient 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°. CONCLUSION Patients 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.

Abstract
A flatfoot deformity is a multiplanar foot deformity characterized by forefoot abduction and supination and hindfoot valgus. With progressive pathology, a rigid deformity may develop. In the setting of a rigid deformity, the appropriate procedure to use is not without controversy. The extent of joints to involve in the arthrodesis depends on the ability to obtain a plantigrade foot. Both double and triple arthrodesis have been suggested. Care must be taken to avoid lateral column shortening and loss of foot reduction when fusing the CC joint. The concerns about lateral skin breakdown led some surgeons to describe a single medial incision for a triple or modified double arthrodesis. The necessity of bone grafting has been controversial. Implant selection is essential to achieve solid stabilization of the arthrodesis sites. To decrease the risk of overcorrection and malunion, the surgeon should be familiar with the hindfoot biomechanics and generate, based on the clinical examination and imaging, a meticulous preoperative plan to address and balance both the soft tissue and bony deformity.

Abstract
INTRODUCTION The treatment of pathologic changes to the talus and surrounding joints presents a unique challenge to the foot and ankle surgeon. The purpose of this systematic review is to summarize the literature for unconstrained (no surrounding fusion or replacement) total talus replacement (TTR) and evaluate whether it leads to improved clinical and radiographic outcomes and appropriate safety metrics. METHODS Concepts of talus and arthroplasty were searched in MEDLINE, Embase, CINAHL Complete, and Scopus from 2005 to 2021. Inclusion Criteria were 1) previous trauma to the talus, 2) post-traumatic or degenerative arthritis to the tibiotalar joint, 3) avascular necrosis of talus, 4) multiple failed prior interventions, and 5) inflammatory arthropathy to tibiotalar joint. Manuscripts in non-English languages or those with concomitant total ankle arthroplasty or revision arthroplasty were excluded. RESULTS Twenty-two studies of 191 patients (196 ankles) were included. Nineteen studies utilized third generation implants, two studies used first generation (n = 9) and one study used second generation implants (n = 14) made largely of ceramic (n = 84), cobalt chrome (n = 49), or titanium (n = 24). Patient-reported outcome measures were favorable in all described categories (Table 4) with ten studies reporting an average postoperative change of + 2.92° of dorsiflexion and - 2.05° plantarflexion at final follow-up. The most common adverse outcome was adjacent joint arthritis with five studies reporting some degree of postoperative, degenerative changes in the surrounding joints (n = 52). CONCLUSION TTR is an alternative to joint sacrificing procedures to maintain range of motion through the tibiotalar joint and allow for maintenance of normal foot and ankle biomechanics. Despite promising early- and mid-term outcomes, future, prospective, randomized research should be conducted to better assess survivorship and complication rates with direct comparison of TTR to existing forms of salvage options for advanced talar pathology.

Abstract
BACKGROUND End-stage ankle arthritis is a debilitating condition often necessitating total ankle replacement (TAR). Tendo-Achilles lengthening (TAL) and gastrocnemius recession (GR) are commonly performed with TAR to improve ankle dorsiflexion (DF). No studies to date have radiographically analyzed tibiopedal motion to guide surgical management. The purpose of this study is to determine the effect of a TAL or GR during TAR on radiographic tibiopedal range of motion (ROM). METHODS A retrospective review of a prospectively maintained database was conducted followed by a propensity score-matched analysis of 110 patients who underwent TAL (n = 26), GR (n = 29), or no lengthening procedure (n = 55) with TAR. Minimum of 1-year ROM radiographic follow-up was required. Exclusion criteria included (1) calcaneal osteotomies, (2) simultaneous or previous hindfoot or midfoot arthrodesis, (3) prior ankle arthrodesis, or (4) revision TAR. Demographic data were extracted from the TAR database. Radiographic assessment included tibiopedal dorsiflexion (DF) and plantarflexion (PF). RESULTS DF improved by 2.8 degrees (P = .0286) and by 6.0 degrees (P < .0001) in the TAL and GR cohorts, respectively, with no difference in the control group (+0.7 degrees, P = .3764). PF was decreased by 4.5 degrees (P = .0152) and by 7.2 degrees (P = .0002) in the TAL and GR cohorts, respectively, with no difference in the control group (-0.2 degrees, P = .8546). Minimal differences were observed for total arc of motion for all 3 groups (control 0.5 degrees, GR -1.2 degrees, TAL -1.7 degrees), all of which were nonsignificant (all P > .05). There was no between-group difference in the change in overall arc of motion between the groups (P = .3599). GR resulted in a greater increase in DF (6.0 vs 2.8 degrees; P = .1074), with a reciprocal greater decrease in PF (7.2 vs 4.5 degrees; P = .2416) compared with the TAL cohort. CONCLUSION Both TAL and GR increased postoperative DF; however, this was accompanied by a reciprocal loss in PF. Minimal differences were observed for total arc of motion. Patients should be counseled that concomitant procedures performed to increase DF will do so at the expense of PF. LEVEL OF EVIDENCE Level III, retrospective review of prospectively collected data.

Abstract
BACKGROUND The risk-benefit profiles of simultaneous total ankle arthroplasty (TAA) compared with sequential TAA continue to be debated. There are limited case series reporting outcomes after bilateral TAA, with no previous comparison of simultaneous TAA with sequential TAA. Patients with bilateral pathology represent a unique population with an overall more debilitating condition. Thus, we aimed to compare bilateral simultaneous and sequential TAAs, including perioperative complications and patient-reported outcome measures. METHODS We performed a comparative cohort study of patients who underwent primary bilateral TAA, performed in a simultaneous or sequential fashion, from 2007 to 2019 at a single academic center. Data on patient demographic characteristics, comorbidities, perioperative complications, reoperations, and implant failures were collected. Patient-reported outcome measures included preoperative and postoperative visual analog scale (VAS) scores for pain, Short Form-36 Health Survey (SF-36) scores, and Short Musculoskeletal Function Assessment (SMFA) scores. RESULTS A total of 50 patients (100 ankles) were included, with 25 patients (50 ankles) each in the bilateral simultaneous and sequential cohorts. The mean follow-up was 52.2 ± 27.3 months (range, 24 to 109 months). The mean time between sequential TAAs was 17.5 ± 20.1 months (range, 3 to 74 months). The mean patient age was 64.3 ± 10.6 years (range, 21 to 76 years), and 32 (64.0%) were men. The majority of patients (28 patients [56.0%]) had primary osteoarthritis. Both cohorts had equivalent preoperative patient-reported outcome measures and experienced improvements in all measures, which were maintained at the final follow-up with no significant between-group differences (all p > 0.05). There were no differences between the simultaneous TAA group and the sequential TAA group in perioperative complication rates (22.0% compared with 24.0%; p = 0.7788), reoperations (12.0% compared with 10.0%; p = 0.7354), 5-year reoperation-free survival (88.0% compared with 90.0%; p = 0.4612), or failure-free survival (100%). One patient in the simultaneous TAA cohort required metal component revision at 8 years postoperatively. CONCLUSIONS The patient-reported outcome measures, complications, and prosthesis survival of patients who underwent bilateral simultaneous TAA were comparable with those of patients who underwent bilateral sequential TAA. We advocate that simultaneous bilateral TAA is a safe and effective method for the treatment of bilateral end-stage ankle osteoarthritis. LEVEL OF EVIDENCE Therapeutic Level III .

Abstract
Category: Midfoot/Forefoot Introduction/Purpose: Hallux rigidus (HR) is the most common arthritic condition of a foot with a prevalence of up to 45% in people aged >75 years-old. First metatarsophalangeal joint (MTPJ) arthrodesis has been the historical gold standard treatment for late-stage HR. Polyvinyl alcohol (PVA) hydrogel implants have similar biomechanical properties as native cartilage, and thus have gained popularity as a joint-sparing technique that provides preservation of MTPJ motion. Initial literature demonstrated pain relief and functional outcomes equivalent to first MTPJ arthrodesis and excellent five-year survivorship. However, recent studies report variable failure rates on PVA hydrogel implants for HR. The purpose of this study was to report the five-year experience and outcomes of PVA hydrogel implants for the treatment of HR performed by a single surgeon. Methods: Electronic health records were queried from August 2016 to August 2021 for patients who underwent primary PVA hydrogel implant hemiarthroplasty (Cartiva Synthetic Cartilage Implant; Cartiva Inc, Alpharetta, GA) for symptomatic late-stage HR. All patients were treated by a single foot and ankle fellowship trained orthopaedic surgeon. A minimum of six months follow- up was required. Patient demographics and perioperative data were collected. Preoperative and postoperative range of motion, visual analog scale (VAS) pain scores, and radiographs were evaluated. Complications and the overall implant survivorship were reported. A Kaplan-Meier analysis was used to evaluate implant survival. Descriptive and univariate statistics were used to analyze data. A total of 196 primary PVA hydrogel implant procedures were performed of which 146 had a minimum six-month follow-up and were included. The mean follow-up was 14.5 (+- 11.9) months. Results: The majority of patients were female (n=103, 70.5%) with a mean age of 58.1 (+-10.1) years-old, BMI of 27.3 (+-5.2) Kg/m2, and an ASA score < 3 (n=131, 89.7%). The majority of patients had stage II or III disease (n=115, 78.8%). Patients experienced significant improvement in VAS (p<0.0001) and hallux dorsiflexion (p=0.0005) postoperatively. There was a total of 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 9 (6.2%) revision PVA hydrogel implant procedures and 9 (6.2%) first MTJP arthrodesis. The one-and two-year survival to any revision surgery (n=18) were 89.1% and 80.5%, respectively. The one- and two-year survival to MTPJ arthrodesis (n=9) were 95.9% and 86.3%, respectively (Table 1). Conclusion: In the largest single-surgeon series reported, first MTPJ hemiarthroplasty with a PVA hydrogel implant resulted in significantly improved pain and hallux dorsiflexion at an average of 15 months postoperatively. There was a high two-year survivorship of 86.3% until failure with required first MTPJ arthrodesis. Future prospective studies should be performed to refine the indications for PVA hydrogel implants and identification of risk factors for failure.

Abstract
➢ The preparation methodology for platelet-rich plasma (PRP) may have important clinical implications with varying effectiveness with leukocyte, platelet, and growth factor concentrations. ➢ There is high-quality evidence to support the superiority of PRP over corticosteroids in the case of chronic plantar fasciitis. ➢ There is moderate-quality to high-quality evidence for PRP's ability to increase tendon thickness with no capacity to decrease pain, increase function, or augment percutaneous tenotomy in Achilles tendinopathy. ➢ There is insufficient evidence to support PRP injections in the definitive treatment of Achilles tendon rupture. However, PRP may contribute to postoperative recovery after tendon rupture repair, but this requires further research. ➢ The biochemical theory supporting the clinical use of PRP must be reinforced with high-level evidence research. Based on the current literature, PRP may serve as a viable treatment method in chronic plantar fasciitis. Further high-quality, comparative studies with longer clinical follow-up are required to support recommendations for use of PRP in the treatment of Achilles tendon pathology.

Abstract
Category: Hindfoot Introduction/Purpose: Talar avascular necrosis (AVN) is a difficult pathology to diagnose and manage. Traditional treatment options include both joint sparing procedures (vascularized bone graft, core decompression, intraosseous stem cell injection) and joint sacrificing procedures (arthrodesis or arthroplasty). Three dimensional (3D) printed total talus replacement (TTR) has recently gained more popularity as an intervention to salvage joint motion in patients with talus pathology. Although vascularized bone grafting can treat localized talar AVN, failure of this procedure to improve talar vascularity and prevent further subchondral collapse may require revision surgery. This is the first study to compare outcomes of patients with talar AVN who underwent primary 3D printed TTR and patients who underwent a secondary TTR subsequent to failure of a free vascularized medial femoral condyle (MFC) flap. Methods: This case series analyzed the outcomes of two patients who underwent a secondary 3D printed TTR subsequent to failure of the index revascularization procedure using an MFC flap in 2016. These patients were compared to a cohort of patients who underwent a primary 3D printed TTR to treat talar AVN between 2016 and 2019. Preoperative and postoperative assessment included ankle range of motion, foot and ankle outcome score (FAOS), visual analogue scale (VAS) pain scores, and radiographic imaging. A minimum 12-month follow-up period was reported for patients. Results: Within the group that underwent a secondary TTR after a failed revascularization, both patients had a mean followup of 23.5 months. The 25 patients in the comparison group who all underwent a primary 3D printed TTR had an mean follow-up period of 22.1 (range:12-43) months. All patients in the study experienced improved VAS pain scores and ankle dorsiflexion post- operatively. In the secondary 3D printed TTR group, both patients demonstrated reduced plantarflexion of 20 degrees and ankle motion of 15 degrees relative to the comparison group which showed a minimal increase in both. When analyzing FAOS functional outcome score subscales, patient two demonstrated improvement in pain from 44 to 46, symptoms from 29 to 46, and activities of daily living from 47 to 76. Patient one experienced a decrease in sports and recreation from 15 to 5 and quality of life from 38 to 31. Conclusion: This case series demonstrated poor functional outcomes of two patients who underwent 3D printed TTR after talar revascularization with MFC grafts when compared to the cohort of patients who solely underwent a primary 3D printed TTR for talar AVN. Further investigation is warranted to determine which patients may benefit from a revascularization procedure or a primary 3D printed TTR.

Abstract
Category: Ankle; Hindfoot; Trauma Introduction/Purpose: Prosthetic substitution of the talus presents a unique challenge to the foot and ankle surgeon. The shear and compressive forces on the talus and its tenuous blood supply lead to high rates of avascular necrosis with possible talar collapse. The purpose of this systematic review is to evaluate whether total talus replacements (TTR) lead to improved clinical outcomes with appropriate safety metrics in patients with a history of avascular necrosis or significant trauma. Methods: Concepts of talus and arthroplasty were searched in MEDLINE (PubMed), Embase (Elsevier), CINAHL Complete (EBSCOhost), and Scopus (Elsevier) from the database's inception through November 4, 2021. Inclusion Criteria were 1) previous trauma to the talus, 2) post-traumatic or degenerative arthritis to the tibiotalar joint, 3) avascular necrosis of talus, 4) multiple failed prior interventions, 5) degenerative osteoarthritis to the tibiotalar joint, and 56) inflammatory arthropathy to tibiotalar joint. Manuscripts in non-English languages or those with concomitant total ankle arthroplasty or revision arthroplasty were excluded. All study designs were eligible according to the Journal of Bone and Joint Surgery criteria level I-IV. The modified Coleman Methodology Score was used to evaluate study quality and the Methodological Index for Non-Randomized Studies criteria was used to assess risk of bias. Results: Twenty-two studies of 191 patients (196 tali) at an average age of 50 (14-80) years were included (Figure 1a). Nineteen studies utilized third generation implants, two studies used first generation (n=9), and one study used second generation implants (n = 14) made of ceramic (n=82), cobalt chrome (n=49), or titanium (n=23) (Figure 1b). Radiographic and patient-reported outcomes are outlined in Figure 1c. The most common adverse outcome was osteosclerosis of the tibia (n=24), calcaneus (n=19), and navicular (n=5). Additionally, hindfoot varus (n=3), ankle discomfort (n = 3), decreased subtalar motion (n=7), periprosthetic fracture (n=1), calcaneal fracture (n=1), delayed wound healing (n=3), hindfoot valgus (n=1), prosthetic stem sunken into the talar neck (n=1), superficial peroneal nerve neuroma (n=1), loosening (n=2) were reported. Eight revisions were reported. Conclusion: TTR is an appealing option to maintain range of motion through the tibiotalar joint and allow for maintenance of more normal foot and ankle biomechanics. Given promising early- and mid-term outcomes, TTR is becoming more widely used in the setting of talar collapse. Still, high complication rates, especially adjacent joint osteoarthritis, may remain under-reported in the literature given inadequate long-term follow-up. Future research should aim to expand upon the indications of TTR, elucidate survivorship and complication rates, and directly compare TTR to existing forms of salvage options for advanced talar avascular necrosis.

Abstract
Category: Ankle Arthritis; Ankle; Hindfoot Introduction/Purpose: The utilization of total ankle arthroplasty (TAA) has increased over the past decade to include bilateral TAAs. The risk-benefit profiles of simultaneous versus staged joint arthroplasty continues to be debated in the literature. There are limited case series reporting outcomes after bilateral TAA with no previous comparison of simultaneous versus staged TAA. It is important to study patients with bilateral pathology as they represent a unique population often with a differing arthritis etiology and an overall more debilitating condition. Thus, we aim to compare bilateral simultaneous versus staged TAAs including perioperative complications and patient reported outcome measures (PROMs). Methods: We performed a comparative cohort study of patients who underwent primary TAA from 2007 to 2019 at a single academic center. Inclusion criteria were primary bilateral TAA performed in simultaneous or staged fashion in patients over 18 years of age. Exclusion criteria were patients with less than two-years follow-up and those with previous tibiotalar arthrodesis or infection. Patient demographics, comorbidities, perioperative complications, and PROMs were collected. PROMs included preoperative and postoperative visual analog scale (VAS) for pain, the Short Form-36 (SF-36) Health Survey, the American Orthopaedic Foot and Ankle Society (AOFAS) score, and the Short Musculoskeletal Function Assessment (SMFA) bother and function sub-scores. Bivariate tests of significance were used to compare variables between the two cohorts. Results: Fifty patients were included with an average clinical follow-up was 52.2 (+-27.3; range 24-109) months. The mean time between staged TAA surgeries was 17.5 months (+-20.1, range 3-74). The mean age was 64.3 (+-10.6, range 21-76) years with 32 (64.0%) men. Many patients had primary osteoarthritis (n=28, 56.0%). Both cohorts experienced improvement in all PROMs at one year, which were maintained at final follow-up with no significant between-group differences (p >0.05). There were no differences in perioperative complication rates with similar overall complications (22.0% vs. 24.0%; p=0.7788) and reoperations (6.0% vs 5.0%; p=0.7354) between the simultaneous and staged cohorts, respectively. The two-year and five-year reoperation-free survival were 96.0% and 90.0% for the staged cohort and 94.0% and 88.0% for the simultaneous cohort, respectively (p=0.4612) Both cohorts had 100% failure-free survival up to eight-years postoperative. One patient in the simultaneous cohort required metal component revision at eight years postoperative. Conclusion: The results of bilateral simultaneous TAA, including patient reported outcomes, perioperative complications, and component survival are comparable to patients undergoing staged TAA. When performed under surgeon expertise in appropriately selected patients, we advocate that simultaneous bilateral TAA is a safe and effective method for the treatment of bilateral end-stage ankle osteoarthritis. Potential benefits of simultaneous TAA warranting further investigation include decreased anesthesia events, surgery time, tourniquet time, length of hospitalization, recovery and rehabilitation time, and overall cost. Future investigations will include dedicated analyses of radiographic outcomes and cost comparisons between these two cohorts.

Abstract
Category: Midfoot/Forefoot; Bunion Introduction/Purpose: Hallux valgus (HV) is recognized as a triplanar deformity comprising axial abduction, sagittal hypermobility, and coronal pronation of the first metatarsal. A first tarsometatarsal (TMT) arthrodesis may be used to address all three planes of deformity. The Lapiplasty system (Treace Medical Concepts, Inc., Ponte Vedra, FL) was developed to reproducibly address triplanar deformity. However, the Lapiplasty system is costlier than other fixation constructs. Because healthcare is increasingly value-focused, we sought to determine if the more expensive Lapiplasty system improved radiographic outcomes or decreased complication rates over standard cross-screw fixation. We hypothesized that HV patients undergoing first TMT arthrodesis with the Lapiplasty system would have equivalent radiographic correction and similar complication rates when compared to patients treated with cross-screw fixation. Methods: In this multi-center, IRB-approved retrospective study, consecutive series of patients who underwent 1st TMT arthrodesis for HV, either with cross-screw fixation at Institution A, or Lapiplasty at Institution B, were identified by registry search. Inclusion criteria included age over 18 and preoperative and minimum 6-month postoperative weight-bearing AP and lateral radiographs. Exclusion criteria included primary conditions other than hallux valgus and previous first ray surgeries or ipsilateral arthrodeses. Hallux valgus angle (HVA), intermetatarsal angle (IMA), and tibial sesamoid position (TSP) were measured preoperatively and at final follow-up, and clinic notes were reviewed to identify complications and reoperations. To compare cohorts, Mann-Whitney U tests and Fisher's Exact tests were applied for continuous and discrete variables, respectively. To examine preoperative-postoperative changes, Wilcoxon signed rank tests were used. Multivariable regressions tested the effect of fixation constructs on postoperative radiographic parameters, adjusted for preoperative radiographic measurements, age, sex, and BMI. Results: 65 patients were included in each group, with 121 (93.8%) female patients, mean (SD) age 54.7 (14.8), BMI 25.8 (5.2), and radiographic follow-up time 8.9 (6.7) months. The Lapiplasty cohort had greater BMI (26.8 vs. 24.7, P = .048), and there were no significant differences between groups in age, sex distribution, and radiographic follow-up time. Radiographic measurement data is displayed in Table 1. After adjusting for age, sex, BMI, preoperative HVA, and preoperative IMA, fixation with Lapiplasty was significantly associated with lower postoperative IMA (b=-2.03, 95% CI = [-2.78, -1.37], P < .001) and lower postoperative HVA (b= -7.48; 95% CI = [-9.69, -5.26]; P < .001), but not postoperative sesamoid position. There were no significant differences between cohorts in the incidence of complications or reoperations. Conclusion: We found that use of the Lapiplasty system was associated with better radiographic hallux valgus correction, as evidenced by lower postoperative HVAs and IMAs, compared to standard technique with crossing screws. The clinical significance of these findings is unclear, as complication and reoperation rates were similar between groups. Future research assessing longer- term outcomes, patient-reported outcome data, and cost-benefit analysis will be necessary to further compare techniques and fixation systems.

Abstract
Late-stage talar avascular necrosis (AVN) results in devascularization of the talus with osteonecrosis and subchondral collapse. A combined total ankle and total talus replacement (TATTR) with hindfoot arthrodesis may be utilized for end-stage talar AVN with tibiotalar and hindfoot joint arthritis. The purpose of this study is to evaluate the short-term outcomes of combined TATTR with hindfoot arthrodesis. Patients who underwent a combined TATTR or TTR with a hindfoot arthrodesis (subtalar with or without talonavicular arthrodesis) from 2016 to 2020 were retrospectively reviewed. Patient demographics, comorbidities, and surgical data were collected. Outcomes included the Visual Analog Scale (VAS) scores, range of motion, radiographic parameters, union rates, and complications. A total of 18 patients were reviewed. Nine patients were included with an average of 19.4 months follow-up. Significant postoperative improvements were observed in VAS scores (P < .001), ankle plantarflexion (P = .04), talocalcaneal height (P = .03), and tibiotalar alignment (P = .02). All patients achieved a successful union of their subtalar and talonavicular joints arthrodesis. There was one reoperation for a persistent varus ankle deformity. This is the first study to evaluate the clinical outcomes, radiographic outcomes, and union rate in combined TATTR with hindfoot arthrodesis. The early results demonstrated significant clinical improvement with 100% hindfoot union rate and no prosthetic failure.Level of Evidence: IV.

Abstract
Background: In orthopaedic surgery departments, foot and ankle fellowship directors are tasked to create a robust clinical curriculum for trainees, while division chiefs manage the division's delivery of patient care. The primary aim of this study was to describe characteristics of foot and ankle surgery fellowship directors and division chiefs in an effort to recognize trends or disparities in leadership traits. Methods: The American Orthopaedic Foot and Ankle Society (AOFAS) fellowship directory for 2021 to 2022 was reviewed for AOFAS-recognized fellowship programs in the United States. Between March 2021 and June 2021, 48 fellowship directors and 23 publicly recognized division chiefs were administered an electronic survey to collect demographic, educational, and professional data. Univariate and bivariate statistical analyses were performed. Results: A total of 42 of the 48 (87.5%) fellowship directors and 18 of the 23 (78.3%) division chiefs responded to the questionnaire. Of the 48 fellowship directors, 45 (93.8%) were male, 43 (89.6%) identified as Caucasian, their average age at leadership appointment was 42.6 ± 7.5 (range, 32-70) years, and the average time between fellowship graduation and leadership appointment was 9.9 ± 7.8 (range, 0-36) years. Of the 23 chiefs, 22 (95.7%) were male, 20 (87.0%) identified as Caucasians, their average age at leadership appointment was 41.7 ± 7.8 (range, 32-53) years, and the average time between fellowship graduation and leadership appointment was 9.8 ± 6.8 (range, 2-21) years. The average H-index for the chiefs was greater than that of the fellowship directors (18.4 vs 13.4, P = .0373) when controlling for years of training>. Conclusion: The majority of current leaders identify as middle-age Caucasian males, demonstrate high research productivity, and have attended a select number of the same residency and fellowship training programs. By demonstrating the lack of diversity within foot and ankle surgery leadership, this study serves as a call to action for making inclusivity a priority.Levels of Evidence: Level IV: Cross-sectional study.

Abstract
BACKGROUND In cases of large osteochondral lesions of the talus (OLTs), fresh structural or bulk osteochondral allograft transplantation has yielded favorable outcomes in several retrospective and few prospective case series. The purpose of this study was to prospectively evaluate patients who received fresh structural allograft transplantation of the talar shoulder. METHODS A prospective evaluation of patients who received a fresh structural allograft of an OLT was performed. Preoperative imaging included magnetic resonance imaging (MRI) and/or computed tomography (CT) with plain radiographs. The following patient-reported outcomes questionnaires were administered preoperatively and yearly after surgery: 36-Item Short-Form Health Survey (SF-36), visual analog scale (VAS) for pain, and the Short Musculoskeletal Functional Assessment (SMFA). Preoperative and postoperative imaging were evaluated for allograft assimilation, evidence of arthritic changes, or functional range of motion abnormalities. RESULTS Thirty-one patients with a mean age of 41.4 years (±14.1, range 18-69) underwent structural fresh osteochondral allograft transplantation to the talar shoulder and were included in this study. The mean follow-up was 56.2 months (±36.1, range 24-142). The majority of patients were female (n=17, 54.8%), reported some history of prior ankle trauma (n=21, 67.7%), and underwent prior ankle surgery (n=23, 74.2%). The mean lesion size on CT scan was 1879 mm3 (n = 27) compared to the mean lesion size of 3877 mm3 (n = 21) on MRI. There was a significant improvement in the mean preoperative VAS score (P < .0001), SF-36 score (P < .0005), SMFA bother index (P < .0015), and the SMFA function index (P < .0001) at final follow-up. A total of 15 (48.4%) patients underwent an additional surgery following their osteochondral allograft transplant, most commonly arthroscopic debridement or removal of hardware, performed at an average of 25.2 (±13.0) from their index procedure. There was one failure that required a total ankle replacement. The overall graft survival rate was 96.8%. CONCLUSION Fresh, structural allograft transplantation resulted in significant improvement in patient-reported postoperative pain and function in patients suffering from OLTs. The graft survival rate was 96.8% at a mean of 56.2 months follow-up, with half of patients requiring a second procedure. LEVEL OF EVIDENCE Level IV, prospective case series.

Abstract
BACKGROUND Approximately 56% of patients diagnosed with carpal tunnel syndrome present with bilateral symptoms; however, few studies have investigated bilateral simultaneous endoscopic carpal tunnel release (ECTR) and postoperative effect on return to activity. The purpose of this study was to evaluate the length of recovery in patients who received bilateral simultaneous ECTR, including pain medication requirements, return to activities of daily living, return to work, and return to recreational activities. METHODS A retrospective analysis was performed on patients who underwent bilateral ECTR by a single hand fellowship-trained surgeon from 2013 to 2019. Demographic, operative, and clinical outcomes were collected via chart review and a telephone interview. Student t tests and χ2 tests were conducted for analysis. RESULTS Eighty patients were included in the study; 40 were successfully contacted for telephone interview follow-up. Patients reported an average of 2 days of use of postoperative narcotic pain medication and an average of 5, 7, and 19 days of return to activities of daily living, work, and recreational activities, respectively. Female patients reported more days of narcotic pain medications (1 day vs 3 days, P = .0483) and an average of longer return to work than men (9 days vs 5 days, P = .0477). Manual laborers reported longer return to work (9 days vs 5 days, P = .0500). Older patients (aged >65 years) reported longer return to recreational activities (39 days vs 11 days, P = .0189). CONCLUSIONS Simultaneous bilateral ECTR is a successful procedure with shorter recovery times than reported previously. Female patients, manual laborers, and older patients experience a longer recovery and should be counseled appropriately.

Abstract
Background: Scaphoid nonunion advanced collapse (SNAC) is a common form of wrist arthritis, the treatment of which depends on the arthritic stage. The Vender classification serves to describe SNAC arthritis based on a single posteroanterior (PA) radiograph. The purpose of this study was to evaluate the intraobserver and interobserver agreement of the Vender classification, comparing multi versus single radiographic views. Methods: A retrospective review of patients with SNAC arthritis who underwent a proximal row carpectomy or a 4-corner fusion was performed. The included patients had 3 radiographic views of the pathologic wrist. Fifteen patients were analyzed by 5 blinded reviewers. Wrists were graded using the Vender classification first on the PA view and then using multiview radiographs. The intraobserver and interobserver agreement was determined using weighted kappa analysis. χ2 tests were calculated comparing the evaluation between single- versus multiview radiographs and determining a higher Vender stage. Results: Multiview radiographs demonstrated a higher intraobserver κw compared with single-view radiographs (0.72 vs 0.66), both representing substantial agreement. The average interobserver agreement was moderate (κw of 0.48) for single view and slight (κw of 0.30) for multiview evaluation. Evaluating multiview radiographs was 6.37 times more likely to demonstrate Vender stage 3 arthritis compared with single view (odds ratio = 6.37 [confidence interval, 3.81-10.64], P < .0001). Conclusion: Reviewing multiview radiographs more commonly yielded Vender stage 3 osteoarthritis classification. The decreased interrater reliability in the multiview analysis is likely related to the increased number of articular surfaces evaluated. Using a single PA view may underestimate the severity of arthritis present.

Abstract
Background: The purpose of our study was to review a series of patients with scaphoid fractures to determine whether there was an association between lunate morphology and progression to delayed union or nonunion when treated operatively or nonoperatively. Secondary aims included evaluation of the relationship between lunate morphology and scaphoid fracture location. Methods: A retrospective review of all patients with a diagnosis of scaphoid fracture was performed at our institution between 2014 and 2017. Medical records and radiographs were evaluated to determine lunate morphology, scaphoid fracture location, treatment, and time to union. Differences between groups were determined using χ2 analysis with significance set at P <.05. Multiple logistic regression analyses were used to evaluate scaphoid union in the setting of lunate morphology when controlling for confounders. Results: A total of 169 patients were included; 45.0% (n = 76) of patients had type I lunate morphology, and 55.0% (n = 93) had type II. In all, 64.5% (n = 49) of patients with type I lunate and 68.8% (n = 64) with type II lunate had a fracture at the scaphoid waist. Among all patients with a scaphoid fracture, type II lunates were more likely than type I lunates to progress to nonunion when treated both operatively and nonoperatively (18.3% vs 4.0%, P = .0042). Lunate facet size was not shown to be a significant risk factor for nonunion among patients with a type II lunate (P = .4221). Conclusions: Patients with a scaphoid fracture and type II lunate morphology were more likely to progress to nonunion than patients with a type I lunate.

Return to Play and Performance After Anterior Cruciate Ligament Reconstruction in National Football League Players. 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
Avascular osteonecrosis (AVN) of the talus (AVNT) is a painful and challenging clinical diagnosis. AVNT has multiple known risk factors and etiologies and presents at different stages in severity. Given these unique factors, the optimal treatment solution has yet to be determined. Both joint-preserving and joint-sacrificing procedures are available, including core decompression and arthrodeses. Recently, new salvage and replacement techniques have been described including vascularized pedicle bone grafts and total talus replacement using patient-specific prosthesis; however, evidence remains limited. This review examines the current trends AVNT treatment and the emerging data behind these novel techniques.

Abstract
PURPOSE To evaluate the short-term outcomes of endoscopic proximal hamstring repair including clinical outcomes, patient-reported outcomes, and complications. METHODS A retrospective analysis was performed on consecutive patients who underwent endoscopic proximal hamstring repair from 2013-2018 by a senior sports medicine orthopaedic surgeon. Demographic, operative, clinical data, complications, and patient-reported outcomes were collected and analyzed including the International Hip Outcome Tool-12 (iHOT-12), Single Assessment Numeric Evaluation (SANE), modified Harris Hip Score (mHHS), and the Hip Outcome Score activities of daily living scale (HOS-ADL). RESULTS Thirty patients were included with a minimum 24.0- and average 44.0-month follow-up. The average age was 52.0 years (standard deviation [SD], 14.2), and 80.0% (n = 24) were women. Most patients presented with a history of refractory insertional tendinosis (83.3%, n = 25) and an average of 34.0 months of symptoms prior to surgical intervention. Two-year patient-reported outcomes were clinically acceptable with a postoperative iHOT-12 of 81.9 (SD, 21.1), SANE 78.8% (SD, 20.0), mHHS 89.6 (SD 13.4), and HOS-ADLs 87.2% function (SD, 15.9). Nine patients (30%) had available preoperative iHOT-12 scores. Among these patients, the mean increase in iHOT-12 was 46.3 (P = .0005; n = 9). Eighty percent (n = 24) of patients achieved the iHOT-12 patient acceptability symptomatic state. Complications (3%) included 1 atraumatic rerupture. Four patients participated in an organized sport and 18 in recreational sport with a return to play of 100% and 72.2%, respectively. All patients returned to work. Some 76.7% (n = 23) of patients reported return to their baseline level of physical activity, and 73.3% (n=22) of patients reported complete resolution of pain at last follow-up. There was a 90.0% (n=27) satisfaction rate. CONCLUSIONS Short-term follow-up for endoscopic proximal hamstring repair shows high patient satisfaction (90.0%) and clinically significant patient-reported outcomes with minimal residual pain and a low complication rate (3%).

Abstract
BACKGROUND In young athletes, an association exists between an increased posterior tibial slope (PTS) and the risk of primary anterior cruciate ligament (ACL) injury, ACL graft rupture, contralateral ACL injury, and inferior patient reported outcomes after ACL reconstruction. In spite of this, there is no consensus on the optimal measurement method for PTS in pediatric patients. The purpose of this study was to evaluate the reliability of previously described radiographic PTS measurement techniques. METHODS A retrospective review was performed on 130 patients with uninjured knees between the ages of 6 and 18 years. The medial PTS was measured on lateral knee radiographs by four blinded reviewers using three previously described methods: the anterior tibial cortex (ATC), posterior tibial cortex (PTC), and the proximal tibia anatomic axis (PTAA). The radiographs were graded by each reviewer twice, performed 2 weeks apart. The intrarater and inter-rater reliability were assessed using the intraclass correlation coefficient (ICC). Subgroup analyses were then performed stratifying by patient age and sex. RESULTS The mean PTS were significantly different based on measurement method: 12.5 degrees [confidence interval (CI): 12.2-12.9 degrees] for ATC, 7.6 degrees (CI: 7.3-7.9 degrees) for PTC, and 9.3 degrees (CI: 9.0-9.6 degrees) for PTAA (P<0.0001). Measures of intrarater reliability was excellent among all reviewers across all 3 methods of measuring the PTS with a mean ICC of 0.87 (range: 0.82 to 0.92) for ATC, 0.83 (range: 0.82 to 0.87) for PTC, and 0.88 (range: 0.79 to 0.92) for PTAA. The inter-rater reliability was good with a mean ICC of 0.69 (range: 0.62 to 0.83) for the ATC, 0.63 (range: 0.52 to 0.83) for the PTC, and 0.62 (range: 0.37 to 0.84) for the PTAA. Using PTAA referencing, the PTS was greater for older patients: 9.9 degrees (CI: 7.7-9.4 degrees) vs 8.5 degrees (CI: 9.2-10.7 degrees) (P=0.0157) and unaffected by sex: 9.5 degrees (CI: 8.8-10.1 degrees) for females and 9.0 degrees (CI: 8.0-10.0) for males (P=0.4199). There were no major differences in intrarater or inter-rater reliability based on age or sex. CONCLUSIONS While the absolute PTS value varies by measurement technique, all methods demonstrated an intrarater reliability of 0.83 to 0.88 and inter-rater reliability of 0.61 to 0.69. However, this study highlights the need to identify PTS metrics in children with increased inter-rater reliability. LEVEL OF EVIDENCE IV, Case series.

Abstract
Osteochondral lesions of the talus (OLTs) are difficult to treat. Despite a multitude of interventions, there are no generally-agreed-upon guidelines regarding treatment. The objective of this study was to conduct a systematic review of clinical outcomes after fresh osteochondral allografts transplantation of the talus. PubMed, the Cochrane Central Register of Controlled Trials, EMBASE, and Medline were searched using PRISMA guidelines. Studies that evaluated outcomes after fresh osteochondral allograft transplantation for OLTs were included. Clinical outcomes, according to standardized scoring systems, such as the American Orthopaedics Foot & Ankle Society (AOFAS) Ankle/Hindfoot Scale and the Visual Analog Scale (VAS) were compared across studies. The literature search yielded 12 eligible studies with a mean Coleman Methodology Score of 68.1 (57-79). A total of 191 patients were included with an average age of 37.5 (17-74) years and average follow-up of 56.8 (6-240) months. The AOFAS Ankle/Hindfoot score was obtained pre- and postoperatively in 6 of the studies and had significant improvements in each (p < .05). Similarly, the VAS pain score was evaluated in 5 studies and showed significant decreases from pre- to postoperatively (p < .05). While there were no reported short-term complications, 21.6% of patients required minor subsequent procedures, most commonly arthroscopic debridement and hardware removal. The aggregate graft survival rate was 86.6%. Based on these findings, osteochondral allograft transplantation for OLTs results in positive outcomes with high rates of graft survival and patient satisfaction at intermediate follow-up.

Abstract
BACKGROUND The purpose of this study was to evaluate gender differences in patient outcomes and complications following total ankle replacement (TAR). METHODS Consecutive patients who underwent primary TAR from July 2007 through May 2016 were prospectively followed and retrospectively reviewed. Demographic, operative, patient-reported outcomes (PROs), and complication data were collected and analyzed. PROs included the visual analog scale (VAS), 36-Item Short-Form Health Survey (SF-36), American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot scale, and Short Musculoskeletal Function Assessment (SMFA). A total of 475 patients were evaluated, including 248 males (52.2%) and 227 females (47.8%) with an average of 56.8 months follow-up. RESULTS Women were more likely to have inflammatory arthritis (13.7% vs 2.8%; P < .01) and significantly worse preoperative SF-36 total, SF-36 mental health component, AOFAS total, AOFAS pain, SMFA function, and SMFA bother scores (all P < .05). Both genders demonstrated significant improvement in PROs at 1, 2, and 5 years. The magnitude of improvement was similar between genders for all PROs (all P < .05) with the exception of SF-36 physical function, which was greater in men. Females underwent more nonrevision reoperations (32.2% vs 22.6%; P = .0191), but there was no significant difference in failure rates (male 7.3% vs female 3.5%; P = .07). The reoperation and failure rates at 2 years postoperation were 10.1% and 1.6% for men and 18.5% and 0.9% for women, respectively. CONCLUSION Women undergoing TAR were more likely to have worse preoperative PROs and higher rates of nonrevision reoperations, which remains true when controlling for their increased incidence of inflammatory arthritis. However, women reported similar improvements in PROs and had similar prosthetic survival rates as men. Increased understanding of these disparities, combined with gender-based interventions, may further advance patient outcomes.

Abstract
BACKGROUND Body mass index (BMI), American Society of Anesthesiologists (ASA) score, and Elixhauser Comorbidity Index are measures that are utilized to predict perioperative outcomes, though little is known about their comparative predictive effects. We analyzed the effects of these indices on costs, operating room (OR) time, and length of stay (LOS) with the hypothesis that they would have a differential influence on each outcome variable. METHODS A retrospective review of the institutional database was completed on primary TKA patients from 2015 to 2018. Univariable and multivariable models were constructed to evaluate the strength of BMI, ASA, and Elixhauser comorbidities for predicting changes to total hospital and surgical costs, OR time, and LOS. RESULTS In total, 1313 patients were included. ASA score was independently predictive of all outcome variables (OR time, LOS, total hospital and surgical costs). BMI, however, was associated with intraoperative resource utilization through time and cost, but only remained predictive of OR time in an adjusted model. Total Elixhauser comorbidities were independently predictive of LOS and total hospital cost incurred outside of the operative theater, though they were not predictive of intraoperative resource consumption. CONCLUSION Although ASA, BMI, and Elixhauser comorbidities have the potential to impact outcomes and cost, there are important differences in their predictive nature. Although BMI is independently predictive of intraoperative resource utilization, other measures like Elixhauser and ASA score were more indicative of cost outside of the OR and LOS. These data highlight the differing impact of BMI, ASA, and patient comorbidities in impacting cost and time consumption throughout perioperative care.

Abstract
Background Revision shoulder stabilizations are becoming increasingly common. Returning to play after revision shoulder stabilizations is important to patients. Purpose To evaluate the return-to-play rate after revision anterior shoulder stabilization using arthroscopic, open, coracoid transfer, or free bone block procedures. Study Design Systematic review; Level of evidence, 4. Methods All English-language studies published between 2000 and 2020 that reported on return to play after revision anterior shoulder stabilization were reviewed. Clinical outcomes that were evaluated included rate of overall return to play, level of return to play, and time to return to play. Study quality was evaluated using the Downs and Black quality assessment score. Results Eighteen studies (1 level 2; 17 level 4; mean Downs and Black score, 10.1/31) on revision anterior shoulder stabilization reported on return to play and met inclusion criteria (7 arthroscopic, 5 open, 3 Latarjet, and 3 bony augmentation), with a total of 564 revision cases (mean age, 27.9 years; 84.1% male). The weighted mean length of follow-up was 52.5 months. The overall weighted rate of return to play was 80.1%. The weighted mean rate of return to play was 84.0% (n = 153) after arthroscopic revision, 91.5% (n = 153) after open revision, 88.1% (n = 149) after Latarjet, and 73.8% (n = 65) after bone augmentation. The weighted mean rate of return to same level of play was 69.7% for arthroscopic revision, 70.0% for open revision, 67.1% for Latarjet revision, and 61.8% after bone block revision. There were 5 studies that reported on time to return to play, with a weighted mean of 7.75 months (4 arthroscopic) and 5.2 months (1 Latarjet). The weighted mean rates of complication (for studies that provided it) were 3.3% after arthroscopic revision (n = 174), 3.5% after open revision (n = 110), 9.3% after Latarjet revision (n = 108), and 45.8% after bone block revision (n = 72). Conclusion Revision using open stabilization demonstrated the highest return-to-play rate. Revision using Latarjet had the quickest time to return to play but had higher complication rates. When evaluated for return to same level of play, arthroscopic, open, and Latarjet had similar rates, and bone block had lower rates. The choice of an optimal revision shoulder stabilization technique, however, depends on patient goals. Higher-quality studies are needed to compare treatments regarding return to play after revision shoulder stabilization.

Abstract
Proximal hamstring injuries can present as chronic tendinosis, acute strain, partial tendinous avulsions, or complete 3-tendon rupture. Nonoperative management for chronic insertional tendinosis and low-grade tears includes activity modification, anti-inflammatories, and physical therapy. Platelet-rich plasma injections, corticosteroid injections, dry needling, and shock wave therapy are newer therapies that also may provide benefit. Surgical indications include complete, proximal avulsions; partial avulsions with least 2 tendons injured with more than 2 cm of retraction in young, active patients; and partial avulsion injuries or chronic tendinosis that have failed nonoperative management. Surgical management entails open primary repair, endoscopic primary repair, or augmentation/reconstruction.

Abstract
BACKGROUND We aimed to perform an economic analysis and compare the clinical outcomes between inpatient and short-stay designation total ankle replacement (TAR). METHODS We performed a retrospective study on 178 consecutive patients undergoing primary inpatient versus short-stay designation TAR during the 2016 and 2017 fiscal years. Patient demographics, concomitant procedures, perioperative complications, patient-reported outcomes, and perioperative costs were collected. RESULTS The mean age of our cohort was 62.5 ± 9.6 years (range, 30-88 years), with a significant difference in age (64.1 vs 58.5 years) (P = .005) and Charlson Comorbidity Index (3.3 ± 1.9 vs 2.3 ± 1.4; P = .002) for the inpatient and short-stay designation groups, respectively. At a mean follow-up of 29.6 ± 11.8 months (range, 12-52.3 months), there was no difference in complications between groups (P = .97). The inpatient designation TAR group had a worse baseline Short Musculoskeletal Functional Assessment (SMFA) function score (76.1; 95% CI, 70.5-81.6) than the short-stay designation TAR group (63.9; 95% CI, 52.5-75.3) while achieving similar final postoperative SMFA function scores for the inpatient (55.2; 95% CI, 51.1-59.2) and short-stay (56.2; 95% CI, 48.2-64.2) designation TAR groups (P > .05). However, the inpatient designation TAR group showed a significantly greater mean improvement in SMFA function score (20.9; 95% CI, 19.4-22.4) compared with the short-stay designation TAR group (7.7; 95% CI, 3.7-11.1) (P = .0442). The total direct cost was significantly higher for the inpatient designation group ($15 340) than the short-stay designation group ($13 002) (P < .001). CONCLUSION While inpatient designation TARs were more comorbid, short-stay designation TARs were associated with a 15.5% reduction in perioperative costs, comparable complication rates, and similar final postoperative patient-reported outcome scores compared with inpatient TARs.

Outcomes After Revision Anterior Shoulder Stabilization: A Systematic Review. Orthop J Sports Med 2020; 8:2325967120922571. [PMID: 32528993 PMCID: PMC7263126 DOI: 10.1177/2325967120922571] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2020] [Accepted: 02/12/2020] [Indexed: 12/24/2022] Open
Abstract
Background Primary shoulder stabilization is successful, but there continues to be a risk of recurrence after operative repair, particularly in the young athlete. It is important for surgeons to understand the outcomes after various revision stabilization techniques to best counsel patients and manage expectations. Purpose To analyze recurrent instability and revision surgery rates in patients who underwent revision anterior glenohumeral stabilization procedures with either arthroscopic repair, open repair, coracoid transfer, free bone block, or capsular reconstruction. Study Design Systematic review; Level of evidence, 4. Methods We performed a systematic review of level 2 to 4 evidence studies using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Clinical studies of revision anterior glenohumeral stabilization (arthroscopic repair, open repair, coracoid transfer, free bone block, or capsular reconstruction) with a minimum 2-year follow-up were analyzed. The rate of recurrent instability, rate of revision surgery, patient-reported outcomes, and range of motion were extracted and reported. Study methodological quality was evaluated using the Downs and Black quality assessment score. Results A total of 37 studies met inclusion criteria and were available for analysis: 20 studies evaluated arthroscopic repair, 8 evaluated open repair, 5 evaluated Latarjet procedure, 3 evaluated bone block, and 2 evaluated capsular reconstruction. There was 1 study included in both arthroscopic and Latarjet procedures, for a total of 1110 revision cases. There was 1 level 2 study, and the remainder were level 3 or 4 with poor Downs and Black scores. Participants analyzed were most commonly young (weighted mean age, 26.1 years) and male (78.4%). The weighted mean clinical follow-up after revision surgery was 47.8 months. The weighted mean rate of recurrent instability was 3.8% (n = 245) after the Latarjet procedure, 13.4% (n = 260) after open repair, 16.0% (n = 531) after arthroscopic repair, 20.8% (n = 72) after bone block, and 31.0% (n = 35) after capsular reconstruction. The weighted mean rate of additional revision surgery was 0.0% after bone block, 0.02% after the Latarjet procedure, 9.0% after arthroscopic repair, 9.3% after open repair, and 22.8% after capsular reconstruction. Patient-reported outcomes and objective measures of range of motion and strength improved with all revision techniques. Conclusion The current review identifies a deficiency in the literature pertaining to consistent meaningful outcomes and the effect of bone loss after revision shoulder stabilization. Published studies demonstrate, however, that revision shoulder stabilization using arthroscopic, open, coracoid transfer, or bone block techniques yielded satisfactory objective and patient-reported outcomes. The Latarjet procedure exhibited the lowest recurrent instability rate. This study confirms that recurrent instability remains a common problem, despite revision shoulder stabilization. The quality of research in revision shoulder stabilization remains poor, and higher quality studies are needed to establish best practices for treatment of this complex problem.

Abstract
BACKGROUND Subtalar distraction arthrodesis (SDA) was developed as a means of treating the symptoms of subtalar arthritis. Despite almost 30 years of research in this field, many controversies still exist regarding SDA. The objective of this study was to present an overview of outcomes following SDA, focusing on surgical technique as well as clinical and radiographic results. METHODS MEDLINE and EMBASE were queried and data abstraction was performed by 2 independent reviewers. Inclusion criteria for the articles were (1) English language, (2) peer-reviewed clinical studies with evidence levels I to IV, (3) with at least 5 patients, and (4) reporting clinical and/or radiographic outcomes of SDA. RESULTS Twenty-five studies matched the inclusion criteria (2 Level III and 23 Level IV studies) including 492 feet in 467 patients. The most common indication for SDA was late complications of calcaneus fractures. Many different operative techniques have been described, and there is no proven superiority of one method over the other. The most commonly reported complications were nonunion, hardware prominence, wound complications, and sural neuralgia. All studies showed both radiographic and clinical improvement at the last follow-up visit compared with the preoperative evaluation. Pooled results (12 studies, 237 patients) demonstrated improved American Orthopaedic Foot & Ankle Society ankle-hindfoot scores with a weighted average of 33 points of improvement. CONCLUSION SDA provides good clinical results at short-term and midterm follow-up, with improvement in ankle function as well as acceptable complication and failure rates. Higher quality studies are necessary to better assess outcomes between different operative techniques. LEVEL OF EVIDENCE Level III.

Endoscopic Proximal Hamstring Tendon Repair for Nonretracted Tears: An Anatomic Approach and Repair Technique. Arthrosc Tech 2020; 9:e483-e491. [PMID: 32368468 PMCID: PMC7189203 DOI: 10.1016/j.eats.2019.11.022] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2019] [Accepted: 11/26/2019] [Indexed: 02/03/2023] Open
Abstract
Proximal hamstring injuries are common, and open surgical repair with suture anchors has been the gold standard when surgical intervention is warranted. Endoscopic techniques offer the opportunity of surgical repair with smaller incisions to limit complications and expedite rehabilitation. The purpose of this technique guide is to describe a modified endoscopic technique that allows a safe and anatomic repair of proximal hamstring injuries. The patient is positioned prone with the feet at the head of the bed, table in reverse Trendelenburg, and knees flexed to 90°. Four portals are used, 3 in horizontal alignment within the gluteal fold and 1 directly superior to the ischial tuberosity. The sciatic nerve is identified, dissected, and mobilized away from the operative field. Retraction sutures help retract the gluteus maximus and further protect the sciatic nerve. Dissection is within the interval between the conjoint and semimembranosus tendons. The tendons are freed and mobilized, the ischial tuberosity is decorticated, and an anatomic repair is performed via 4 suture anchors, 2 at each tendon footprint. Advancements in arthroscopy have permitted adequate visualization and exposure of the hamstring footprint, thus allowing for an anatomic repair with increased protection of the sciatic nerve and decreased resources and cost.

The Role of Malnutrition in Ninety-Day Outcomes After Total Joint Arthroplasty. J Arthroplasty 2019; 34:2594-2600. [PMID: 31239176 DOI: 10.1016/j.arth.2019.05.060] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2019] [Revised: 05/08/2019] [Accepted: 05/30/2019] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Research has linked malnutrition to more complications in total joint arthroplasty (TJA) patients. The role of preoperative albumin in predicting length of stay (LOS) and 90-day outcomes remains understudied. Often, an albumin cut-off ≤3.5 g/dL is used as proxy for malnutrition, although this value remains understudied. This preoperative level may be missing some patients at risk for adverse events post TJA. METHODS TJA patients at a single institution from 2013 to 2018 were reviewed for preoperative albumin level. In total, 4047 cases (total knee arthroplasty: 2058; total hip arthroplasty: 1989) had available data, including 90-day readmissions, 90-day emergency department (ED) visits, and postoperative LOS. RESULTS About 5.6% experienced a readmission and 9.6% had at least one ED visit within 90 days. Overall prevalence of malnutrition was 3.6%, and this cohort experienced a longer average LOS (3.5 vs 2.2 days, P < .0001) and was more likely to experience a readmission (16% vs 5%, P < .0001) or ED visit (18% vs 9%, P = .0005). Additionally, albumin ≤3.5 g/dL was correlated with more frequent discharge to skilled nursing facility/rehab (30.8% vs 14.7%, P < .0001), increased risk for 90-day readmission with univariable (odds ratio [OR] 1.79, P < .0001) and multivariable logistic regression (OR 1.55, P < .0001), and increased risk for 90-day ED visits with univariable (OR 1.62, P < .0001) and multivariable regression (OR 1.35, P < .0001). The optimal albumin cut-off was 3.94 g/dL in a univariable model for 90-day readmission. CONCLUSION Screening for malnutrition may serve a role in preoperative evaluation. An albumin cutoff value of 3.5 g/dL may miss some at-risk patients.
