RESUMO
INTRODUCTION: Total ankle replacement (TAR) is an effective treatment for end-stage osteoarthritis. The aim of this systematic review was to assess the age of patients undergoing TAR in prospective comparative studies. Our hypothesis is that the age reported in most recent papers might be lower than those reported in older papers. METHODS: This systematic review was performed using Pubmed, Scopus, EMBASE and Cochrane databases. Only Level I and II studies dealing with TAR were included. Data regarding demographics, study design, number of cohorts in each study, year of publication and year/years in which surgery was performed were extracted. A two-fold analysis was conducted building groups of patients based on the year of publication and creating 1) two groups (before and after the median year) and 2) three groups (using tertiles) in order to compare age of patients operated in different period of times. A comparison was also performed considering the median year of surgery for patients undergoing TAR. RESULTS: Overall 59 cohorts (42 studies, published between 1999 and 2023; median year of publication: 2017) were included (6397 ankles, 6317 patients, median age 63 years). The difference between the median age for 27 cohorts published until 2016 (weighted median 63 years; IQR, 62.5-64) and the median age for 32 cohorts published after 2017 (weighted median 63.2 years; IQR, 63-67.8) was not statistically significant (p = 0.09). The division in tertiles did not reveal any significant change in the weighted median age at surgery (T1 (1999-2014; 63.2 years; IQR, 62.8-64.1), T2 (2015-2018; 63 years; IQR,63-63.5) and T3 (2019-2023; 63.2 years; IQR, 62.6-67.8)) over time (p = 0.65). The median age of patients operated between 1999 and 2008 vs 2009 and 2023 (data from 48 cohorts) was not different either (p = 0.12). CONCLUSION: According to this review of prospective studies published between 1999 and 2023, the median age for patients undergoing TAR over the last two decades has been 63 years, remaining steady with no significant changes over time. LEVEL OF EVIDENCE: Level II - systematic review including Level I and Level II studies.
RESUMO
Periprosthetic joint infections (PJIs) are a prominent subject of discussion in orthopedics and are frequently debated at conferences and congresses. In the context of PJIs affecting the knee, the decision between following a one-stage or two-stage treatment approach has historically been a pivotal consideration. The first option is limited by indications and potentially devastating complications in case of failure, whereas the second is widely accepted as the gold standard. Initially, the spacer was conceived solely to restore and maintain knee space after removal of the implant. An articulating spacer was introduced to mitigate patient limitations and improve knee function and quality of life. Two main types of articulating spacers are utilized in knee PJI treatment: the mold spacer and the metal-on-poly spacer. This text outlines a technique for metal-on-poly spacer implants. Based on our experience and the existing literature, this approach facilitates early full weight bearing and faster recovery of the knee's range of motion, ultimately improving the quality of life after surgery, thus allowing the spacer retention for an extended period, as suggested by the 1.5-stage revision.
RESUMO
BACKGROUND: The gold standard treatment for periprosthetic joint infections is the two-stage revision that includes the spacer placement before definitive reimplantation. The management of PJI affects patients' joint function and, subsequently, their mental health. Even though significant advances have been achieved, little to no attention has been paid to the psychological implications. So, based on standardized patient-reported outcome measures (PROMs), this study aimed to clarify the effect of spacer treatment of infected hip and knee arthroplasties on patients' mental health. METHODS: We performed research on the literature on PJIs in the English language using the MEDLINE database with the search strings "spacer" OR "spacers" AND "hip" OR "knee" AND "SF-12" OR "SF-36" OR "EQ-5" OR "mental" OR "depression" OR "anxiety." The reference lists of selected articles were also hand-searched for any additional articles. RESULTS: A total of 973 published papers were extracted, and 9 papers were finally included. A total of 384 patients who underwent spacer placement for PJI were identified. Of these 384 patients, 54% were female. The mean age ranged from 62 to 78.2 years. Of the11 papers identified for this review, 4 analyzed only hip spacers, including 119 patients; 4 only knee spacers, evaluating 153 patients; while a single study included 112 patients for both joints. CONCLUSIONS: Patients with the spacer are living in a state of mental upset, albeit better than the preoperative state. Clinical improvement with the review is not assured. The alteration of mental state turns out not to be transient for all the patients.
RESUMO
BACKGROUND: Several arthroscopic glenoid bone augmentation techniques have been introduced to treat patients affected by anterior shoulder instability associated with critical bone loss. The efficacy of the different arthroscopic bony procedures has not been compared yet. PURPOSE: To compare the recurrence, complication, and reoperation rates of the arthroscopic Latarjet (AL) and arthroscopic free bone block (ABB) procedures for anterior shoulder instability. STUDY DESIGN: Meta-analysis and systematic review; Level of evidence, 4. METHODS: A systematic search was conducted in MEDLINE/PubMed, Web of Science, and Embase to identify clinical studies reporting the outcomes of the AL and ABB procedures. The following search phrases were used: "Arthroscopic" AND "Bone Block" OR "Bone Graft," and "Arthroscopic" AND "Glenoid Augmentation" OR "Glenoid Reconstruction," and "Arthroscopic" AND "Latarjet" OR "Coracoid Graft" OR "Coracoid Transfer." Exclusion criteria were <24 months of minimum follow-up, sample size <10 cases, revision after previous glenoid bone grafting, epilepsy, and multidirectional instability. Data regarding the study design, patient characteristics, surgical technique, and outcomes were extracted and analyzed. A proportional meta-analysis was conducted to compare the complication, recurrence, and reoperation rates between the 2 groups. Multiple subgroup analyses were performed to analyze the incidence of each complication and assess the weight of different fixation methods (in the whole cohort) or different graft types (in the ABB group). The modified Coleman Methodology Score was used to assess the risk of bias. RESULTS: Of 5010 potentially relevant studies, 18 studies regarding the AL procedure (908 cases) and 15 studies regarding the ABB procedure (469 cases) were included. The 2 groups were comparable in age (P = .07), sex (P = .14), glenoid bone loss (P = .14), number of preoperative dislocations (P = .62), proportion of primary and revision procedures (P = .95), length of follow-up (P = .81), modified Coleman Methodology Score (P = .21), and level of evidence (P = .49). There was no difference in the recurrence (P = .88), reoperation (P = .79), and complication (P = .08) rates. The subgroup analyses showed a higher rate of hardware-related complications for screw fixation compared with flexible fixation (P = .01). CONCLUSION: The AL and ABB procedures had similar recurrence, reoperation, and complication rates. Screw fixation of the bone graft was related to an increased risk of complications compared with flexible fixation. REGISTRATION: CRD42022368153 (PROSPERO).

Background: We reviewed the shoulder arthroplasty (SA) literature to correlate citations, methodological characteristics and quality of most-cited articles in this field. We hypothesized that a greater number of citations would be found for high-quality clinical studies. Methods: We searched the Web of Knowledge database for the 50 most-cited articles about SA and collected author name, publication year, country of origin, journal, article type, level of evidence (LoE), subject of paper, type of arthroplasty and metrics (number of citations and citation rate). Coleman Methodology Score (CMS) was computed for clinical articles. Statistical analysis of variance and correlation coefficients were used to investigate the relationship between different variables. Results: Out of the selected 50 studies on SA, 26% were nonclinical. There were 15,393 citations overall (mean 307.8), with a mean 19.5 citations per year (range 48.3-6.7). Thirty or 60% of all articles were LoE IV. All studies were published between 1984 and 2011 in 8 journals. Reverse SA (RSA) was the most common subject (36% of studies). The United States was the country responsible for most contributions (50% of studies). CMS ranged from 81 to 38 (mean 59.6). RSA received the highest number of citations (P < .001), independently from country of origin (P = .137) and LoE (P = .723). CMS correlated with citation rate (r = 0.397; P = .013) and publication year (tau = 0.397; P = .013), but not with LoE (P = .204). Conclusion: In SA literature, citation rate positively correlates with methodological quality of a study, independently from publication country and LoE. Among most-cited papers, RSA is the most common standalone subject.
RESUMO
Ankle arthrodesis is commonly performed to treat end-stage ankle osteoarthritis. The aim of this study was to determine whether the use of fibular autograft might increase the fusion rate and decrease the complication rate in ankle arthrodesis (AA) fixed using cannulated screws. To perform this PRISMA-compliant proportional meta-analysis, multiple databases were searched for studies in which patients undergone AA (using exclusively cannulated screws and augmented with fibular bone graft) were followed. The characteristics of the cohort, the study design, surgical details, the nonunion and complication rate at the longest follow-up were extracted and recorded. The modified Coleman Methodology Score (mCMS) was applied to appraise the quality of studies. Two groups were built: arthrodeses fixed with screws combined with cancellous autograft (G1) and arthrodeses fixed with screws combined with cancellous autograft and augmented with a lateral fibular onlay (G2). A third group (arthrodeses fixed with screws and no graft, G3) was extracted from previous literature for a further comparison. Overall, we included 306 ankles (296 patients) from ten series (ten studies). In G1 and G2 there were 118 ankles (111 patients) and 188 ankles (185 patients), respectively. In patients where cancellous autograft was used, a further augmentation with a fibular lateral strut autograft did not change significantly the nonunion (4% [95% CI 1-9] in G1 vs. 2% [95% CI 0-5) in G2, p = 0.99) nor the complication rate (18% [95% CI 0-36] in G1 vs. 13% [95% CI 6-21) in G2, p = 0.71). Upon comparison with 667 ankles (659 patients, G3) in which arthrodeses had been performed without grafting, the nonunion and complication rates did not differ significantly either (pooled estimates: 3% [95% CI 1-3) in G1 + G2 vs. 3% [95% CI 2-4] in G3, p = 0.73 for nonunion; 15% [8-23] in G1 + G2 vs. 13% [95% CI 9-17] in G3, p = 0.93 for complications). In ankle arthrodesis fixed with cannulated screws combined with cancellous autograft at the fusion site, a construct augmentation with a distal fibular onlay strut graft positioned laterally at the ankle joint does not reduce the risk of nonunion or complication. In general, the use of bone graft does not influence significantly the nonunion nor the complication rate as compared to non-grafted screw-fixed ankle arthrodeses.Kindly check and confirm the corresponding author mail id is correctly identified.It's all correct.

BACKGROUND AND AIM: Periprosthetic joint infection (PJI) is among the most common complications of Total Ankle Replacement (TAR) and its management may be challenging. We set out to define which are the criteria currently used to diagnose PJI after TAR. METHODS: This PRISMA-compliant systematic review was registered in the Open Science Framework. Multiple databases were searched including clinical studies in which PJI after TAR was diagnosed and treated. Data were harvested regarding the cohort, the study design and the diagnostic criteria for PJI. Risk of bias was assessed using the modified Coleman Methodology Score (mCMS). RESULTS: Six papers (122 infected TARs) published between 2012 and 2022 were included in this review. Ankle pain with swelling and unexplained increased local temperature were the most common clinical findings leading to a suspicion of PJI. In 100% of cases the diagnosis was confirmed through synovial fluid analysis associated with positive blood tests. In all the revision surgeries intraoperative cultures (at least 3) were performed. In 109 ankles (90%) there was a microbiological isolation. Out of these, 38 (35%) were single organism infections by Staphylococcus coagulase negative and 37 (34%) were single organism infections by Staphylococcus Aureus. The mean mCMS was 37.6 out of 100. CONCLUSIONS: There is a lack of diagnostic criteria specific for PJI after TAR. Clinical and laboratory tests inspired to the knowledge in total knee and total hip arthroplasty are generally adopted in the field of ankle arthroplasty. The quality of evidence for studies included in this review was poor.

OBJECTIVES: To evaluate sensitivity, specificity, and predictive value of Patrick-FABER test in assessing magnetic resonance imaging (MRI) sacroiliitis and addressing the diagnosis of spondyloarthritis (SpA) in subjects with low back pain (LBP). METHODS: Subjects with LBP were consecutively enrolled. The assessors were blinded to patients' clinical, laboratory, or imaging data. All subjects underwent sacroiliac joint MRI to detect presence of sacroiliac oedema or structural changes. RESULTS: One hundred and ten subjects were included in the study [males (61.8%); median age of 45 (21-69) years; LBP duration of 78 (3-240) months]. Patrick-FABER test sign's sensitivity was 76.2% (95% CI: 60.5-87.9%), specificity was 66.2% (95% CI: 53.6-77.2%), positive predictive value (PPV) was 58.1% (95% CI: 44.1-71.3%) and negative predictive value (NPV) was 81.8% (95% CI: 69.1-90.9%) for the diagnosis of sacroiliitis, with an overall diagnostic accuracy of 70%. At the univariate and multivariate analysis, Patrick-FABER test sign was associated with inflammatory lesions of sacroiliitis at MRI and SpA diagnosis. Univariate and multivariate analysis showed an association between smoking status (p=0.01), sacroiliitis, and SpA diagnosis. The odds of having sacroiliitis was 2.7 higher in smokers (OR: 2.7; 95% CI: 1.1-7) as compared to non-smokers and 6.3 higher in those with a positive Patrick-FABER test sign (OR: 6.3; 95%CI: 2.5-15.6) as compared to those with a negative sign. CONCLUSIONS: Our study shows that Patrick-FABER test positivity could represent a useful clinical test for addressing the use of sacroiliac joints MRI and SpA diagnosis in subjects with LBP. Further, smoking habit could represent an associate anamnestic element for addressing the use of sacroiliac MRI.

OBJECTIVE: The purpose of this study was to determine whether the number of cannulated screws used during ankle arthrodesis (AA) might influence the union and complication rate. METHODS: In this Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-compliant PROSPERO-registered systematic review, multiple databases were searched including studies in which patients undergone AA using cannulated screws as exclusive fixation method were followed. Data were harvested regarding the cohort, the study design, the surgical technique, the nonunion, and complication rate at the longest follow-up. Risk of bias was assessed using the modified Coleman Methodology Score (mCMS). Two groups were built (arthrodeses fixed with 2 screws [group 1, G1] vs arthrodeses fixed with 3 screws [group 2 G2]) and compared. RESULTS: Fifteen series of patients from 15 studies (667 ankles) were selected (G1 = 458 ankles and G2 = 209). The pooled proportion estimate revealed a similar nonunion rate in the 2-screw group as compared with the 3-screw group (4% vs 3%; P = .68). The pooled proportion of complications was higher in G1 (19%) than in G2 (8%), but it was not significantly different either (P = .45). After exclusion of "symptomatic hardware and screw removal," the difference was still not significant (P = .28) although it resulted lower in G1 than in G2 (4% vs 8%, respectively). CONCLUSIONS: Using 3 cannulated screws during AA as compared with a 2-screw construct does not significantly reduce the risk of nonunion nor the risk of complications. LEVEL OF EVIDENCE: Level IV, Systematic review of level IV.
RESUMO
Background: Achilles tendon injuries represent one of the most common reasons for referral to orthopaedic surgeons. Purpose: To outline the characteristics, examine trends in publication, and evaluate the correlation between citations and study quality of the 50 most cited articles on Achilles tendon injury. Study Design: Cross-sectional study. Methods: After searching the Web of Science for articles published in orthopaedic journals, we identified the 50 most cited articles on Achilles tendon injury and abstracted their characteristics. Risk of bias was assessed using the modified Coleman Methodology Score (mCMS). Multiple bivariate analyses (Pearson or Spearman correlation coefficient) were used to evaluate the association among number of citations, citation rate (citations/year), 2020 journal impact factor (JIF), year of publication, level of evidence (LoE), study type (tendon rupture or chronic tendinopathy), sample size, and mCMS. Results: The top 50 articles were cited 12,194 times. Each article had a mean ± SD 244 ± 88.8 citations (range, 157-657) and a citation rate of 12.6 ± 5.4 per year (range, 3-28). A total of 35 studies (70%) were published between 2000 and 2010. The citation rate of the 16 most recent studies was almost double that of the 16 oldest studies (17.5 vs 9.9; P < .001). Nineteen studies (49%) were classified as having poor quality (mCMS <50 points). The mean JIF of the 9 journals that published the studies was 5.1. The citation rate correlated with the number of citations (r = 0.56; P < .001), publication year (r = 0.60; P < .001), and LoE (r = -0.44; P = .005). The publication year correlated with the LoE (r = -0.40; P = .01). Study quality in terms of mCMS correlated with the JIF (r = 0.35; P = .03) and LoE (r = -0.48; P = .003) but not the citation rate (P = .15). Conclusion: The mean LoE and the citation rate of the most cited articles on Achilles tendon injury both significantly increased over time. Although the JIF was positively correlated with study quality, almost half of the studies had poor-quality methodology.
RESUMO
OBJECTIVE: Ankle arthrodesis (AA) is often fixed using cannulated screws. The irritation from metalwork is a relatively common complication, but there is no consensus regarding the need to remove the screws on a systematic basis. The aim of this study was to determine (1) the proportion of screws removed after AA and (2) whether predictors of screw removal could be identified. METHODS: This PRISMA-compliant systematic review was part of a larger previous protocol registered on the PROSPERO platform. Multiple databases were searched including studies in which patients undergone AA using screws as exclusive fixation method were followed. Data were harvested regarding the cohort, the study design, the surgical technique, the nonunion and complication rate at the longest follow-up. Risk of bias was assessed using the modified Coleman Methodology Score (mCMS). RESULTS: Forty-four series of patients from thirty-eight studies (1990 ankles, 1934 patients) were selected. The average follow-up was 40.8 months (range 12-110). In all studies, hardware was removed due to symptoms reported by patients and related to the screws. The pooled proportion of removal of metalwork was 3% (95% CI 2-4). The pooled proportion of fusion was 96% (95%CI 95-98), while the pooled proportion of complications and reoperations (excluding the removal of metalwork) stood at 15% (95% CI 11-18) and 3% (95% CI 2-4), respectively. The mean mCMS (50.8 ± 8.1, range 35-66) revealed only an overall fair quality of studies. The univariate analysis and the multivariate model showed that the year of publication (R = - 0.004; p = 0.01) and the number of screws (R = 0.08; p = 0.01) were associated with the screw removal rate. Specifically, we found that over time the removal rate decreased by 0.4% per year and that the use of three screws instead of two reduced the risk of removal of metalwork by 8%. CONCLUSIONS: In this review, removal of metalwork after ankle arthrodesis using cannulated screws was needed in 3% of cases at an average follow-up of 40.8 months. It was indicated only in case of symptoms related to soft tissue irritation from screws. The use of three screws was paradoxically related to a reduced risk of removal of screws as compared to two-screw constructs. LEVEL OF EVIDENCE: Level IV, systematic review of Level IV.

OBJECTIVE: High tibial valgus osteotomy (HTO) is a widely accepted procedure indicated for varus knee with symptomatic osteoarthritis of the medial compartment. However, there is a lack of studies evaluating long term results of this procedure. The primary aim of this study was to evaluate the long-term survival of opening wedge high tibial osteotomy (HTO) for isolated osteoarthritis in the medial compartment of the knee. The secondary objective was to identify independent predictors of conversion to total knee arthroplasty (TKA). METHODS: This is a long term retrospective study of 296 cases of open wedge HTOs performed at a single center (level of evidence IV) between January 2005 and August 2015. Opening wedge medial HTO was always performed after diagnostic arthroscopy. Eighty-three percent of the population (233 patients, 247 procedures) was followed up at a mean 11.6 years (6-17) by telephone interview, to evaluate the possible conversion to TKA. Mean age at the index operation was 42.8 years (range 15-70) and most patients were male (70%). Associated procedures (e.g., platelet rich plasma supplementation, microfractures, meniscectomy, etc.) were carried out at the time of the HTO in 80 (32%) cases. Survival of HTO and its association with age, sex, body mass index, smoking habit, preoperative severity of varus deformity, cartilage status at surgery, and associated procedures were evaluated. Kaplan-Meier and Cox regression analyses were performed. RESULTS: Thirty-three of the 247 HTOs (13.4%) were converted to knee replacement, with 86.6% of the original procedures surviving at a mean 12-year follow-up. Kaplan-Meier survival estimates at 17 years for HTO were 75.5% (95% confidence interval [CI] 66.7-84.3). There was significant difference (P < 0.001) in the 17-year survival rate between obese (55.5%; 95% CI 35.3-75.6) and non-obese (79.7%; 95% CI 70.1-89.2) patients. The determinants of conversion to knee arthroplasty detected at multivariate Cox regression analysis were body mass index, severity of cartilage degeneration in the medial compartment (Outerbridge grade), and age. CONCLUSION: The long-term survival of open wedge HTO for osteoarthritis in the medial compartment of the knee is satisfactory. The risk of conversion to TKA is significantly increased in obese patients. Advanced age and severity of pre-existing cartilage damage may also contribute to the risk of conversion to TKA.

PURPOSE: To compare functional outcomes, complication rates, and survival in patients with intertrochanteric fracture treated with percutaneous compression plate (PCCP) or gamma nail (GN). METHODS: A retrospective study of prospectively collected data of patients treated with PCCP or GN for AO/OTA 31.A1 or AO/OTA 31.A2 fractures was conducted. Sixty-eight consecutive patients treated with PCCP between 2018 and 2020 were enrolled and matched with 68 patients with comparable characteristics treated with GN. The activities of daily living (ADL) index and specific scales for walking ability and need for walking aids at 4 months and 1 year after fracture fixation were chosen as primary outcomes. Postoperative complications and one-year survival were recorded and compared between the two groups. RESULTS: Walking ability and ADLs index decreased and the need for walking aids increased in both groups compared to the prefracture state at both follow-up intervals (p < 0.001), regardless of the treatment received. There was no difference between the two implants in the rate of implant-related complications. One-year survival rate was 78.9% (95% CI 67.0-86.9) and 82.4% (95% CI 71.0-89.5) in patients undergoing PCCP or GN, respectively, with no significant difference between the two groups. CONCLUSIONS: Walking ability, ADLs, complication rate, and 1-year survival are not significantly different when patients undergoing PCCP or GN are compared. The choice of implant may not be decisive for the outcome of treatment of intertrochanteric fractures, provided that stable fixation is ensured.

BACKGROUND: It is unclear whether lateral soft tissue release (LSTR) is required as part of percutaneous hallux valgus (PHV) surgery. The primary aim of this systematic review was to assess whether LSTR reduces the risk of recurrence of hallux valgus deformity. The secondary aims were to assess if LSTR increases the risk of complications, improves the clinical outcome and leads to a greater radiographic correction. METHODS: We performed a PRISMA-compliant PROSPERO-registered systematic review, pooling clinical papers reporting results after PHV surgery into two categories (PHV with (Group 1, G1) and without LSTR (Group 2, G2)) and comparing them. Data regarding the study design, demographics, the surgical procedure and the clinical and radiological outcome were extracted and compared. Risk of bias was assessed using the modified Coleman Methodology Score (mCMS). RESULTS: Sixteen studies were selected (G1:594 feet; G2:553 feet). The pooled proportion of recurrence at a minimum 21-month follow-up (2%, 95%CI 0-3 vs 2%, 95%CI 0-5; p = 0.70) did not differ in the two groups. Similarly, the pooled proportion of complications (27%, 95%CI 17-38 vs 25%, 95%CI 12-37; p = 0.79) was similar. The pre- (p = 0.23) and post-operative AOFAS scores (p = 0.16), the pre-(HVA: p = 0.23) (IMA: p = 0.94) and post-operative radiological angles (HVA: p = 0.47) (IMA: p = 0.2) and the methodological quality of studies (p = 0.2) did not differ either between G1 and G2. CONCLUSION: There is no evidence that LSTR performed during percutaneous HV surgery reduces the risk of recurrence of the deformity at a mean 4-year follow-up nor improves the clinical and radiological outcome. LEVEL OF EVIDENCE: Level IV systematic review of Level I to IV studies.

INTRODUCTION: Bösch osteotomy (BO), which is a first metatarsal subcapital osteotomy stabilised with a K-wire, is a surgical option to correct hallux valgus (HV). The aim of this study was to assess the long-term clinical and radiographic results in a cohort of patients treated at our institution with such osteotomy. METHODS: In this retrospective monocentric single-surgeon cohort study, we included 58 HVs (46 patients) who underwent HV correction by BO and were followed at a minimum of 7 years. The range of motion (ROM), the American Orthopaedic Foot and Ankle Society's Forefoot scale (AOFAS-FS) and the Visual Analogic Scale (VAS) for pain were recorded. On weightbearing radiographs, the Hallux Valgus Angle (HVA), Intermetatarsal Angle (IMA), the Distal Metatarsal Articular Angle (DMAA), and the Lateral Sesamoid Position (LSP) were measured and compared with pre-operative values. The complication rate and first metatarsophalangeal joint stiffness were also assessed. RESULTS: At a mean follow-up of 10 ± 2 (7-17) years, mean ± standard deviation AOFAS-FS and VAS were 89 ± 11 (67-93) and 2.1 ± 2.8 (0-7) points, respectively. In 42 (72%) cases there was no limitation in the choice of footwears. Radiographically, we found a significant improvement in the HVA (from 33.9° ± 6.7 to 18.8° ± 5.6, p < 0.001), in the IMA (14.2° ± 3.1 to 9.4° ± 2.7, p < 0.001), in the DMAA (from 30.3° ± 6.8 to 11.5° ± 5.1, p < 0.001) and in LSP (median value from 3 to 1, p < 0.001). In 36 (62%) cases the ROM was greater than 75° while in 22 (38%) it ranged between 30° and 75°. Minor complications occurred in six (10%) cases, which did not require any further surgery at the longest follow-up. CONCLUSION: Bösch technique provided satisfactory clinical and radiographic outcomes in the treatment of hallux valgus which persisted at a mean 10-year follow-up. The complication rate did not differ from more recent techniques described in literature. LEVEL OF EVIDENCE: Level IV, retrospective cohort study.

Background: Osteoporosis is responsible for fragility fractures, which are associated with impaired quality of life (QoL) and disability. Objective: The aim of the study was to evaluate the QoL in patients affected by osteoporosis and possible determinants. Methods: One-hundred thirty-four subjects followed at the osteoprosis outpatient clinic at our institution completed the QUALEFFO-41 questionnaire for quality of life. All subjects had undergone bone densitometry measurement and the FRAX index, summarizing the risk of fragility fracture, was calculated for each of them. The QoL in these subjects and its possible determinants were investigated with univariate and multiple linear regression analysis. Results: Subjects with osteoporosis had lower scores in the domains of physical and social function of the QUALEFFO questionnaire in comparison with subjects with normal bome mineral density. Main factors associated with impairment in QoL were high FRAX score and body mass index (BMI). Conclusion: Physical and social function is reduced in osteoporotic subjects. High BMI and an increased risk of fragility fracture were main determinants of impairment in the QoL in this study.
RESUMO
A method to detect the presence of infection after Total Joint Arthroplasty is presented. The method is based on Electrical Bioimpedance Spectroscopy and guarantees low latency, non-invasiveness, and cheapness with respect to the state of art. Experimental measurements were carried out on a singular patient who had already undergone bilateral Total Knee Arthroplasty. He was affected by a hematogenous Periprosthetic Joint Infections on the left knee. The right knee was adopted as the reference. Measurements were acquired once before the surgical procedure (Diagnosis Phase) and twice in the postoperative phases (Monitoring Phase). The most relevant frequency range, for diagnosis and monitoring phases, was found to be between 10 kHz to 50 kHz. The healing trend predicted by the decrease of impedance magnitude spectrum was reflected in clinical and laboratory results. In addition, one month after the last acquisition (two months after the surgery), the patient fully recovered, confirming the prediction of the Electrical Bioimpedance Spectroscopy technique.
RESUMO
Lateral extra-articular tenodesis (L.E.T.) have been proposed to reduce the tibia's anterior translation and internal rotation in concomitant to Anterior cruciate ligament (A.C.L.) reconstruction. Recent studies show that the addition of L.E.T. to A.C.L. reconstruction results in a statistically significant reduction in graft failure. The purpose of the present study was to evaluate the clinical outcomes, complications, and rate of return to preinjury sports level in pediatric patients who underwent combined A.C.L. reconstruction with L.E.T. at a minimum 2-year follow-up. The authors retrospectively evaluated 42 pediatric patients at high risk of graft failure who experienced ACLR connected to L.E.T. IKDC and Tegner-Lysholm Knee Scores Scale were used to assess clinical outcomes, and the Tegner Activity Scale to evaluate the return to sport. No graft failure or subsequent surgery related to A.C.L. reconstruction occurred. Furthermore, 88% of patients returned to the sport. Satisfactory clinical results were obtained on a short and medium-term follow-up. These findings help to consider this procedure for active adolescents at a high risk of graft failure to enhance A.C.L. reconstruction.
RESUMO
Snapping a knee related to a biceps femoris tendon subluxation is an uncommon syndrome that could be disabling in patients with high functional requirements such as athletes. We report a case of a 21-year-old soccer player with a painful left snapping biceps femoris tendon due to a varus trauma. He underwent knee arthroscopy and surgical exploration of the knee: the long head of the biceps femoris tendon was partially detached from his fibular insertion and there was a prominence on the fibular head. Reinsertion of the tendon and osteotomy of the fibular head allowed for resolution of all symptoms and the return to sport.
RESUMO
Debridement, antibiotic, and implant retention (DAIR) can be used as a first surgical procedure for acute infections in patients who have well-fixed components. However, its use in hematogenous or late acute infections is still debated. This systematic review of literature aims to clarify the effectiveness of DAIR procedure in the treatment of hematogenous periprosthetic knee infections. DAIR is an effective way to treat acute hematogenous PJIs of the knee and reaches its best efficacy when performed within one week from the onset of symptoms, modular components are exchanged, and a pathogen-oriented antibiotic therapy can be set. It is safe, economic, and effective technique, but has to be performed in a very narrow temporal window.
