RESUMEN

PURPOSE: To assess the effect of kinesiophobia or fear of reinjury on patient-reported outcome measures and physical performance measures in patients with chronic Achilles tendinopathy (AT). METHODS: Three databases were systematically screened for studies from inception to May 22nd, 2023 for literature investigating the impact of kinesiophobia on PROMs or physical performance metrics in AT. The authors adhered to the PRISMA and R-AMSTAR guidelines as well as the Cochrane Handbook for Systematic Reviews of Interventions. Data on demographics, pain, level of activity, self-reported injury severity, quality of life, single-leg hop performance, and heel-raise performance were recorded. Data was presented primarily in a narrative summary fashion. The MINORS score was used for all studies to perform a quality assessment of included studies. RESULTS: Six studies comprising 705 patients were included in this review. Variations of the Tampa Scale of Kinesiophobia (TSK-11 or TSK-17) were used in all studies. TSK scores were strongly correlated with the Pain Catastrophizing Score (PCS) and Visual Analogue Scale (VAS) scores and were correlated with decreased Victorian Institute of Sports Assessment Achilles (VISA-A) and Foot and Ankle Outcome Scores Quality of Life (FAOS-QoL) subscale scores. Kinesiophobia was associated with heel raise completion with conflicting evidence on correlations with hop test performance. CONCLUSION: Increased kinesiophobia scores (> 35 points), measured by TSK are associated with worse PROMs, including increased pain, decreased quality of life, increased self-reported severity, and is also associated with poorer physical performance measures in patients with AT. LEVEL OF EVIDENCE: IV.

RESUMEN

Although replantation of an amputated extremity has been successfully performed, occasionally the surgeon is forced to amputate in the case of an unsalvageable open fracture. These appendages can theoretically act as an autologous 'bone and tissue bank' for patients if they have reconstructable contralateral injuries. We present a case of an athlete who sustained a Gustilo and Anderson IIIC injury on 1 leg resulting in a below knee amputation. Her other lower leg had a traumatic amputation of the heel pad, partial amputation of the calcaneus, and complete Achilles tendon loss. Tissues from this amputated appendage were utilised to restore the anatomy of the contralateral extremity. The distal tibia and the tibialis anterior from the amputated limb were used to reconstruct the missing posterior tuberosity of the calcaneus and the Achilles tendon respectively. The soft tissue deficiency of the heel pad was restored with an anterolateral thigh free flap. At 2-year follow-up, the patient is pain free and back to playing soccer. This case highlights the opportunistic use of amputated parts to reconstruct a calcaneus and Achilles tendon. A multidisciplinary approach with plastic surgeons is required. The main advantage of this 'Spare Part Surgery' philosophy is to provide autologous graft of a similar geometry and to avoid harvesting tissues from an additional donor site.

RESUMEN

The Disability of the Arm, Shoulder and Hand (DASH) and the Patient-Rated Wrist Evaluation (PRWE) scores appear most frequently in the literature when assessing functional outcome after distal radius fracture. We aimed to evaluate if the two questionnaires correlate. We reviewed 258 cases of adults who sustained a distal radius fracture over a one year period. At mean follow-up of 17 months the disability of the arm, shoulder and hand (DASH) and the patient-rated wrist evaluation (PRWE) scores were recorded. The outcome scores for each group were not statistically different (DASH p = 0.86, PRWE p = 0.80). The results of both questionnaires correlated strongly (Spearman's coefficient = 0.90). As the DASH score is potentially influenced by concomitant upper limb problems we suggest that the specific patient rated wrist evaluation (PRWE) be the sole instrument for assessing the functional outcome of distal radius fractures. This will reduce questionnaire fatigue and standardise the literature.

RESUMEN

OBJECTIVE: To determine the effect of deltoid ligament repair on the development of posttraumatic arthritis in logsplitter ankle injuries. METHODS: Design: Retrospective cohort. SETTING: Academic, Level I trauma center. PATIENT SELECTION CRITERIA: Patients ≥18 years of age with logsplitter injuries (OTA/AO 44B, 44C) treated with open reduction internal fixation with or without deltoid ligament repair from January 2008 to October 2021. OUTCOME MEASURES AND COMPARISON: The rate of posttraumatic arthritis (PTOA) development at final follow-up (minimum 6 months) after open reduction internal fixation was evaluated using the Kellgren-Lawrence scale. The achievement of acceptable reduction indicated by articular reduction <2mm, and a medial clear space ≤4mm was assessed at 6 weeks postoperatively with weightbearing radiographs. The effect of deltoid ligament repair on the development of PTOA was investigated. RESULTS: Fifty-nine patients aged 49.1 ± 17.2 years met inclusion criteria with a mean follow up of 16.6 months (range = 6 to 96). Twenty-six of 59 patients (44%) had developed PTOA at final follow-up. Acceptable reduction was achieved in 83.1% (49/59) of fractures. The acceptable reduction rate in fractures undergoing deltoid ligament repair was 100% versus 78% in those without deltoid ligament repair (13/13 vs. 36/46, p=0.017). The rate of PTOA development was significantly lower in patients who underwent deltoid ligament repair (15%) compared to those who did not (52%), p=0.026. Patients who underwent deltoid ligament repair had a significantly reduced rate of PTOA development leading to arthrodesis compared to those who did not (0% vs. 17%, p=0.013). CONCLUSIONS: Logsplitter injuries resulted in a high rate of development of posttraumatic arthritis. An acceptable reduction is required to minimize risk of development of PTOA and progression to arthrodesis. Deltoid ligament repair during open reduction internal fixation may facilitate acceptable reduction, decrease the rate of PTOA and progression to arthrodesis in these injuries. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMEN

Importance: Withdrawal of life-sustaining therapy (WLST) decisions for critically injured trauma patients are complicated and multifactorial, with potential for patients' insurance status to affect decision-making. Objectives: To determine if patient insurance type (private insurance, Medicaid, and uninsured) is associated with time to WLST in critically injured adults cared for at US trauma centers. Design, Setting, and Participants: This retrospective registry-based cohort study included reported data from level I and level II trauma centers in the US that participated in the American College of Surgeons Trauma Quality Improvement Program (TQIP) registry. Participants included adult trauma patients who were injured between January 1, 2017, and December 31, 2020, and required an intensive care unit stay. Patients were excluded if they died on arrival or in the emergency department or had a preexisting do not resuscitate directive. Analyses were performed on December 12, 2023. Exposures: Insurance type (private insurance, Medicaid, uninsured). Main Outcomes and Measures: An adjusted time-to-event analysis for association between insurance status and time to WLST was performed, with analyses accounting for clustering by hospital. Results: This study included 307 731 patients, of whom 160 809 (52.3%) had private insurance, 88 233 (28.6%) had Medicaid, and 58 689 (19.1%) were uninsured. The mean (SD) age was 40.2 (14.1) years, 232 994 (75.7%) were male, 59 551 (19.4%) were African American or Black patients, and 201 012 (65.3%) were White patients. In total, 12 962 patients (4.2%) underwent WLST during their admission. Patients who are uninsured were significantly more likely to undergo earlier WLST compared with those with private insurance (HR, 1.54; 95% CI, 1.46-1.62) and Medicaid (HR, 1.47; 95% CI, 1.39-1.55). This finding was robust to sensitivity analysis excluding patients who died within 48 hours of presentation and after accounting for nonwithdrawal death as a competing risk. Conclusions and Relevance: In this cohort study of US adult trauma patients who were critically injured, patients who were uninsured underwent earlier WLST compared with those with private or Medicaid insurance. Based on our findings, patient's ability to pay was may be associated with a shift in decision-making for WLST, suggesting the influence of socioeconomics on patient outcomes.

RESUMEN

Benign and low-grade malignant bone tumours are often treated with curettage and filling of the resultant defect using any of a number of materials, including autologous bone grafts, allografts, or synthetic materials. The objective of this study was to report our experience using a synthetic bone graft substitute in these patients. Ten consecutive cases (four males, six females; mean age, 36 years) of benign bone tumours were treated surgically at a tertiary musculoskeletal oncology centre, between 2019 and 2021. Following curettage, the contained defects were managed with injectable beta-tricalcium phosphate/calcium sulfate (GeneX; Biocomposites Ltd., Keele, UK). The desired outcomes were early restoration of function and radiographic evidence of healing. No other graft materials were used in any of the patients. The mean follow-up was 24 months (range, 20-30 months). All patients in this series (100%) demonstrated radiographic evidence of healing and resumed their daily living activities. There were no tumour recurrences and no complications were encountered with the use of GeneX. In patients with contained defects following curettage of benign bone tumours, we found GeneX to be a safe and effective filling agent. These findings contrast with some existing studies that have reported local complications with the use of injectable beta-tricalcium phosphate/calcium sulfate.

RESUMEN

Introduction: Metal hypersensitivity affects 10-15% of individuals. Orthopaedic implants contain various metals and, therefore, metal hypersensitivity may impact patient outcomes. Purpose: We report a systematic review of the literature on metal hypersensitivity in patients undergoing foot and ankle (F&A) surgery. Our goal is to provide an overview presenting symptoms, diagnostic methods, treatment, and clinical outcomes. Methods: A comprehensive literature search of Ovid MEDLINE and EMBASE was performed from its inception (01-Jan 1966) to 23-Nov 2021. MeSH search terms on F&A were used including orthopaedic surgeries, metal types, and hypersensitivity. All full-text, English, experimental and observational studies reporting on metal hypersensitivity in the context of foot and/or ankle surgeries using metallic orthopaedic devices were included. Article screening, critical appraisal, and data extraction was performed by two reviewers. Disagreements were resolved by a third reviewer. Results: Fifteen studies were identified, reporting on 45 patients (18 male and 27 female). Median age was 58 years and mean follow-up was 20.8 months. 42 static and three arthroplasty implants were included. In total, 19 patients (42.2%) were diagnosed with metal hypersensitivity to a constituent of their implant, including two (4.4%) patients diagnosed without metal hypersensitivity testing. Twenty-six patients (57.8%) tested negative to their metal implant components. Of the 19 patients allergic to a constituent of their implant, 14 underwent hardware removal and improved. Four patients were asymptomatic and the last was symptomatic, but not revised. Of these, 23 patients retained their hardware (eight with skin reactions) and two symptomatic patients underwent hardware removal. Conclusion: Metal hypersensitivity in the context of F&A surgery is not widely reported. It should be a differential diagnosis in patients who present with hypersensitivity-type symptoms once infection and mechanical failure are ruled out. This data informs a comprehensive algorithm for identifying and treating metal hypersensitivity in F&A patients. Level of evidence: Level IV.

RESUMEN

INTRODUCTION: Treatment for Freiberg's disease is largely conservative. For severe disease and refractory cases, there are various surgical options. The purpose of this study was to report the 5-year clinical outcomes of a modified Weil osteotomy in the treatment of advanced Freiberg's disease. METHODS: Twelve patients (12 feet), with a mean age of 30.7 years (range 17-55), were treated with synovectomy and modified Weil osteotomy of the affected distal metatarsal head. There were 10 females and 2 males. Clinical outcomes were independently evaluated pre and postoperatively using the American Orthopaedic Foot and Ankle Society (AOFAS) scoring system and a subjective satisfaction score. Radiological union was evaluated postoperatively. Nine (75%) feet involved the 2nd metatarsal and 3 feet (25%) involved the 3rd metatarsal. According to the Smillie classification, 6 feet were Grade IV and 6 feet were grade V. RESULTS: No patients were lost to follow up and the mean follow-up time was 5.2 years (4-7). AOFAS scores improved from 48.1 + /- 7.4-88.9 + /- 10.1 postoperatively giving a mean improvement of 40.8 (p < 0.001). In total, 92% of patients were satisfied with their operation at latest follow-up, reporting excellent or good results. All patients had postoperative radiological union. One patient had a superficial postoperative infection that was successfully treated with oral antibiotics. CONCLUSION: Modified Weil osteotomy is an effective treatment for advanced Freiberg's disease with good outcomes and few complications.

RESUMEN

Background: There is currently a scarcity of information and consensus for transportal (arthroscopic or fluoroscopic) joint preparation during tibiotalocalcaneal (TTC) fusion, and therefore this review aims to summarize the available techniques and to evaluate the outcomes after this procedure. Methods: A systematic electronic search of MEDLINE, EMBASE, and Web of Science was performed for all English-language studies published from their inception to April 4, 2022. All articles addressing arthroscopy in TTC nailing were eligible for inclusion. The PRISMA Checklist guided the reporting and data abstraction. Descriptive statistics are presented. Result: A total of 5 studies with 65 patients were included for analysis. All studies used arthroscopic portals for tibiotalar and subtalar joint preparation (in 4 studies) prior to TTC nailing, with 4 studies using an arthroscope and 1 study using fluoroscopy. The overall major complication rate was 13.8%; however, there was only 1 instance of deep wound infection (1.5%) and 4 instances of surgical site infections (6.2%). Full fusion was achieved in 86% of patients with an average time to fusion of 12.9 weeks. The mean American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score preoperatively was 34.0 and postoperatively was 70.5. Conclusion: Although limited by the number of studies, transportal joint preparation during TTC nail ankle fusion is associated with good rates of complications and successful fusion. Level of Evidence: Level III, systematic review of Level III-IV studies.

RESUMEN

Aims: This study aimed to investigate the risk of postoperative complications in COVID-19-positive patients undergoing common orthopaedic procedures. Methods: Using the National Surgical Quality Improvement Programme (NSQIP) database, patients who underwent common orthopaedic surgery procedures from 1 January to 31 December 2021 were extracted. Patient preoperative COVID-19 status, demographics, comorbidities, type of surgery, and postoperative complications were analyzed. Propensity score matching was conducted between COVID-19-positive and -negative patients. Multivariable regression was then performed to identify both patient and provider risk factors independently associated with the occurrence of 30-day postoperative adverse events. Results: Of 194,121 included patients, 740 (0.38%) were identified to be COVID-19-positive. Comparison of comorbidities demonstrated that COVID-19-positive patients had higher rates of diabetes, heart failure, and pulmonary disease. After propensity matching and controlling for all preoperative variables, multivariable analysis found that COVID-19-positive patients were at increased risk of several postoperative complications, including: any adverse event, major adverse event, minor adverse event, death, venous thromboembolism, and pneumonia. COVID-19-positive patients undergoing hip/knee arthroplasty and trauma surgery were at increased risk of 30-day adverse events. Conclusion: COVID-19-positive patients undergoing orthopaedic surgery had increased odds of many 30-day postoperative complications, with hip/knee arthroplasty and trauma surgery being the most high-risk procedures. These data reinforce prior literature demonstrating increased risk of venous thromboembolic events in the acute postoperative period. Clinicians caring for patients undergoing orthopaedic procedures should be mindful of these increased risks, and attempt to improve patient care during the ongoing global pandemic.

RESUMEN

Background: End-stage ankle osteoarthritis is a condition that can be treated with ankle arthrodesis (AA) or total ankle arthroplasty (TAA). The goal of this study is to estimate the 2016-2017 United States' utilization of TAA and AA in specific ambulatory settings and delineate patient and hospital factors associated with the selection of TAA vs AA for treatment of ankle osteoarthritis. Methods: TAA and AA procedures performed for ankle osteoarthritis were identified in the 2016-2017 Nationwide Ambulatory Surgery Sample (NASS) Database. Notably, the NASS database only examines instances of ambulatory surgery encounters at hospital-owned facilities. As such, instances of TAA and AA performed at privately owned or freestanding ambulatory surgical centers or those performed inpatient are excluded from this analysis. Cases were weighted using nationally representative discharge weights. Univariate analyses and a combined multiple logistic regression model were used to compare demographic, hospital-related, and socioeconomic factors associated with TAA vs AA. Results: In total, 6577 cases were identified, which represents 9072 cases after weighting. Of these, TAA was performed for 2233 (24.6%). Based on the logistic regression model, several factors were associated with increased utilization of TAA vs AA. With regard to patient factors, older patients were more likely to undergo TAA, as well as females. Conversely, patients with a higher comorbidity burden were less likely to receive TAA over AA.With regard to socioeconomic factors, urban teaching and urban nonteaching hospitals were significantly more likely to use TAA compared to rural hospitals. Similarly, privately insured patients and those with a median household income of $71 000 or more were also more likely to receive TAA over AA. Private hospitals ("not-for-profit" and "investor-owned") were significantly more likely to offer TAA over AA. Conclusion: Using a large nationally representative cohort, the current data revealed that during 2016-2017, 24.6% of operatively treated cases of end-stage ankle osteoarthritis in the ambulatory setting are treated with TAA. Associations between socioeconomic and hospital-level factors with TAA utilization suggest that nonclinical factors may influence surgical treatment choice for ankle osteoarthritis. Level of Evidence: Level III, retrospective cohort study.

RESUMEN

Background: The safety of outpatient total ankle arthroplasty (TAA), and factors predictive of early complications are poorly understood. The objective of this study was to determine the frequency of early complications in patients undergoing outpatient TAA compared to a matched inpatient TAA cohort. Factors predictive of early complications following TAA are elucidated. Methods: A retrospective review of prospectively collected data from the 2011-2018 American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database was performed. An unadjusted analysis comparing complication rates in outpatient, and inpatient TAA was performed followed by a propensity score-matched cohort analysis. A multivariate logistic regression model was then used to identify significant independent predictors for complications, reoperation, and readmission following TAA. Results: A total of 1487 patients (198 outpatient, 1289 inpatient) undergoing TAA were included in the study. Inpatient TAA was associated with increased 30-day readmission compared with outpatient TAA (3.54% vs 0.51%, P = .032) in a matched cohort analysis. Thirty-eight (2.6%) patients had a minor complication, with 16 (1.1%) patients having a major complication after TAR. Nineteen (1.3%) patients underwent reoperation, and 42 (2.8%) patients were readmitted within 30 days of the index TAR. Multivariate analysis identified factors predictive of early complications to include length of stay (LOS) >2 days, smoking, hypertension, bleeding disorders, and diabetes mellitus. Conclusion: From this relatively limited data set, outpatient TAA appears to be safe for management of end-stage ankle arthritis in select patients. Inpatient status was associated with an increased rate of 30-day readmission following TAA. Postoperative length of stay >2 days, smoking, hypertension, bleeding disorders, and diabetes mellitus were identified to be associated with early postoperative complications following TAA in this cohort. Level of Evidence: Level III, retrospective cohort study.

RESUMEN

CASE: A 54-year-old type 2 diabetic man with a diabetic forefoot ulcer and osteomyelitis successfully underwent a staged reconstruction to salvage his foot. An antibiotic-carrying bone void filler was used to decrease the infection burden after initial debridement. The fifth toe fillet flap was performed to cover the large soft-tissue defect. The patient returned to baseline ambulation at the 1-year follow-up with a well-incorporated flap. CONCLUSION: This case highlights the utility of combining an antibiotic-carrying bone void filler and a toe fillet flap in a two-stage approach to salvage complex diabetic foot ulcers.

RESUMEN

BACKGROUND: Diabetic foot ulcers are associated with significant morbidity and mortality while posing a challenge for healthcare professionals. Offloading is considered the mainstay of treatment. Total contact casting (TCC) is widely used but does not effectively offload the hindfoot. Some studies suggest that a metal stirrup is effective at offloading midfoot and hindfoot ulcers. The primary purpose of this study is to compare the offloading mechanism of TCC to a stirrup cast. METHODS: A pilot observational study assessing 12 healthy volunteers who underwent casting with a TCC or stirrup cast. A sensor (Pedar; Novel GmbH) that measures maximum force, peak pressure, and contact time and area of each foot region, was placed inside the cast to assess the offloading mechanisms of the 2 interventions. RESULTS: We measured a reduction in all plantar foot loading parameters from the TCC to the stirrup cast. The highest reductions of 85% to 96% (±5%-13%) were noted in maximum force and peak pressure under the forefoot (P < .0001) and found reductions in maximum force, the contact area of all regions of the foot, peak pressure and contact time of the forefoot and midfoot, and contact area of the hindfoot (P < .05). CONCLUSION: In this experimental trial of healthy adults, the stirrup cast was more effective than the TCC by offloading the foot mostly in the forefoot and midfoot.

RESUMEN

Four distal femoral axes have been described to aid in the accuracy of transverse plane component alignment in total knee arthroplasty (TKA). These include the surgical epicondylar axis (SEA), the posterior condylar axis (PCA), and the anteroposterior (AP) axis. Therefore, the primary purpose of this study is to identify the axial femoral relationship with the least variation in a Caucasian population awaiting TKA for osteoarthritis. Secondarily, we further plan to determine if these femoral axis relationships differ with respect to sex or preoperative coronal alignment. These anatomic relationships were measured using preoperative magnetic resonance imaging, which was performed within 2 months of the planned operation date for patient specific instrumentation templating. In terms of our primary outcome, the mean SEA/AP angle was 92.8 degrees (standard deviation [SD]: 2.5 degrees), the mean PCA/AP angle was 95.7 degrees (SD: 2.8 degrees), and the mean PCA/SEA angle was 3.4 degrees (SD: 1.8 degrees). Overall, the PCA/SEA relationship had the smallest variance, while the PCA/AP had the most variance for all comparisons. In terms of our secondary outcome, there was no statistical difference between femoral axis relationships based on preoperative coronal plane alignment. In terms of sex differences, the PCA/SEA was significantly higher in female knees compared with males. Females had a PCA/SEA relationship of 4.7 degrees (SD: 1.3 degrees) compared with 2.6 degrees (SD: 1.2 degrees) for males (p < 0.05). By using the PCA/AP axes, the AP axis was externally rotated by 96.7 degrees (SD: 2.3 degrees) in females, compared with 93.2 degrees (SD: 2.1 degrees) in males, from the PCA. In conclusion, our results demonstrate that the PCA/SEA relationship should be used to determine axial rotation in TKA as it shows the least variation. When using the PCA, approximately 5 degrees of external rotation for Caucasian women and 3 degrees of external rotation for the Caucasian men should be dialed into the femoral cutting block to restore anatomic axial rotation. Further evaluation is needed to determine to role of preoperative coronal alignment on distal femoral axial alignment.

RESUMEN

BACKGROUND: Total ankle replacement (TAR) and ankle fusion are effective treatments for end-stage ankle arthritis. Comparative studies elucidate differences in treatment outcomes; however, the literature lacks evidence demonstrating what outcomes are important to patients. The purpose of this study was to investigate patients' experiences of living with both a TAR and ankle fusion. METHODS: This research study used qualitative description. Individuals were selected from a cohort of patients with TAR and/or ankle fusion (n = 1254). Eligible patients were English speaking with a TAR and contralateral ankle fusion, and a minimum of 1 year since their most recent ankle reconstruction. Surgeries were performed by a single experienced surgeon, and semistructured interviews were conducted by a single researcher in a private hospital setting or by telephone. Ankle Osteoarthritis Scale (AOS) scores, radiographs, and ancillary surgical procedures were collected to characterize patients. Themes were derived through qualitative data analysis. RESULTS: Ten adults (8 men, 2 women), ages 59 to 90 years, were included. Average AOS pain and disability scores were similar for both surgeries for most patients. Participants discussed perceptions of each reconstructed ankle. Ankle fusions were considered stable and strong, but also stiff and compromising balance. TARs were considered flexible and more like a "normal ankle," though patients expressed concerns about their TAR "turning" on uneven ground. Individuals applied this knowledge to facilitate movement, particularly during a first step and transitioning between positions. They described the need for careful foot placement and attention to the environment to avoid potential challenges. CONCLUSION: This study provides insight into the experiences of individuals living with a TAR and ankle fusion. In this unusual but limited group of patients, we found that each ankle reconstruction was generally perceived to have different characteristics, advantages, and disadvantages. Most participants articulated a preference for their TAR. These findings can help clinicians better counsel patients on expectations after TAR and ankle fusion, and improve patient-reported outcome measures by better capturing meaningful outcomes for patients. LEVEL OF EVIDENCE: Level IV, case series.
