ABSTRACT

PURPOSE: To evaluate the mid-term clinical outcomes for the non-surgical and surgical management of acute proximal hamstring avulsions. METHODS: Sixty physically active individuals were offered surgical or non-surgical management for their proximal hamstring avulsion injuries. Distal retraction was defined as greater than 2 cm. Primary outcome measures were the Victorian Institute of sport assessment-proximal hamstring tendons (VISA-H) and functional assessment scale for acute hamstring injuries (FASH). Secondary outcome measures included palpable gap (cm), return to sport (RTS) and the ability to perform Nordic hamstring curls. Outcome variables were adjusted in regression models for gender, age, and treatment. RESULTS: Thirty-one patients elected to undertake non-surgical management, and 29 chose surgery with a mean follow-up of 34.8 ± 8.7 and 34.9 ± 7.0 months, respectively. The mean VISA-H for the non-surgical and surgical groups were 87.3 ± 3.4 and 87.9 ± 4.1 (n.s.), respectively. The mean FASH for the non-surgical group was 89.3 ± 2.4 and 88 ± 3.6 for the surgical group (n.s.). This was consistent after adjusting for confounders. The mean gap for the non-surgical group was 4.5 ± 1.09 and 4.9 ± 1.19 cm for the surgical group (n.s.). No significant differences were found in the abilities to perform Nordic hamstring curls (n.s.). Both groups achieved comparable RTS rates (n.s.). On average, the non-surgical group achieved RTS at 5.5 ± 1.2 months post-injury, whereas the surgical group was at 5.7 ± 0.7 months (n.s.). CONCLUSION: Physically active individuals with acute proximal hamstring avulsions and distal retraction of the tendon stump can be managed non-surgically, achieving similar functional levels and RTS compared to patients treated surgically. LEVEL OF EVIDENCE: Level III.

ABSTRACT

Background: The safety and restriction regulations implemented to contain the COVID-19 pandemic significantly impacted people's quality of life compromising the perception of dignity. Preserving dignity for end-of-life patients remains a paramount objective in palliative care. This study aimed to compare dignity levels in terminal cancer patients between pre- and during-pandemic periods. Methods: Dignity was assessed by the Italian version of the Patient Dignity Inventory (PDI-IT) in both pre- and during-pandemic groups of terminal cancer inpatients (hospitalized or admitted in hospice). The 2 groups were compared using non-parametric tests and a multivariate logistic regression analysis to estimate the association of the different dimensions of dignity with COVID-19 period, adjusting for other confounders. The study involved 2 groups of end-of-life cancer patients with a Karnofsky Performance Status (KPS) index less than 50. The first group included 506 patients before COVID-19, and the second group consisted of 156 patients enrolled during pandemic. Results: Existential Distress, Loss of Purpose and Meaning, Physical Symptoms and Dependency, Social Support PDI subscales and PDI Total score were higher in the during-pandemic group. The multivariate regression model partially supported the previous results as Loss of Purpose and Meaning, Social Support, and Existential Distress PDI subscales were associated with during-pandemic period, whereas PDI Physical Symptoms and Dependency and PDI Psychological Distress were not. Conclusion: Social isolation and other restrictions put in place to contain the COVID-19 pandemic may have had a negative impact on the perception of dignity in cancer patients at the end of life.

ABSTRACT

Total knee arthroplasty (TKA) is a gold standard surgical procedure to improve pain and restore function in patients affected by moderate-to-severe severe gonarthrosis refractory to conservative treatments. Indeed, millions of these procedures are conducted yearly worldwide, with their number expected to increase in an ageing and more demanding population. Despite the progress that has been made in optimizing surgical techniques, prosthetic designs, and durability, up to 20% of patients are dissatisfied by the procedure or still report knee pain. From this perspective, the introduction of robotic TKA (R-TKA) in the late 1990s represented a valuable instrument in performing more accurate bone cuts and improving clinical outcomes. On the other hand, prolonged operative time, increased complications, and high costs of the devices slow down the diffusion of R-TKA. The advent of newer technological devices, including those using navigation systems, has made robotic surgery in the operatory room more common since the last decade. At present, many different robots are available, representing promising solutions to avoid persistent knee pain after TKA. We hereby describe their functionality, analyze potential benefits, and hint at future perspectives in this promising field.

ABSTRACT

PURPOSE: Addressing trapezio-metacarpal (TMC) osteoarthritis often involves considering TMC joint replacement. Utilizing TMC prostheses offers advantages such as preserving the thumb length and more accurately replicating the thumb's range of motion (ROM). TMC prostheses have an intrinsic risk of dislocation and aseptic loosening. Analyzing pre- and postoperative imaging can mitigate complications and improve prosthetic placement, providing insights into both successes and potential challenges, refining overall clinical outcomes. MATERIALS AND METHODS: We conducted a prospective analysis of 30 patients with severe TMC arthritis treated with a Touch© (Kerimedical, Geneva, Switzerland) prosthesis in 2021-2023: X-ray and CT protocols were developed to analyze A) the correct prosthesis placement and B) its correlation with clinical outcomes (VAS, Kapandji and QuickDASH scores) by performing Spearman correlation analysis. RESULTS: The average differences in trapezium height and M1-M2 ratio pre- and post-surgery were, respectively, 1.8 mm (SD ± 1.7; p < 0.001) and 0.04 mm (SD ± 0.04; p = 0.017). Pre-to-postoperative M1 axis length increased by an average of 2.98 mm (SD ± 3.84; p = 0.017). Trapezial cup sinking, indicated by the trapezium index, measured 4.6 mm (SD ± 1.2). The metacarpal index averaged at 11.3 mm (SD ± 3.3). The distance between the centers of the trapezium distal surface and the prosthesis cup was 2.23 mm (SD ± 1.4). The Spearman correlation analysis gave the following results: negative correlations were highlighted between postoperative VAS scores and the M1/M2 ratio and residual trapezium height (correlation coefficient: -0.7, p = 0.03 and -0.064, p = 0.03, respectively) at 6 months; a negative correlation was found at the 3-month mark between QuickDASH and the trapezium residual height (correlation coefficient: -0.07, p = 0.01); and a positive correlation was found for the trapezium index at 1 month (correlation coefficient: 0.07, p = 0.03) and 3 months (p = 0.04) using the Kapandji score. Similarly, we found a positive correlation between the distance between the prosthesis and trapezium centers and QuickDASH score at 1 and 3 months (correlation coefficient: 0.066, p = 0.03; correlation coefficient: 0.07, p = 0.05, respectively) and a positive correlation between prosthesis axis and the residual first metacarpal angle with QuickDASH score at 3 months (correlation coefficient: 0.07, p = 0.02). CONCLUSIONS: Pre- and postoperative systematic imaging analysis should become a method for predicting complications and guiding recovery in TMC prosthesis: CT imaging could provide us with radiographical landmarks that are intrinsically linked to clinical outcomes. Further research is necessary to fuel a protocol for the correct intraoperative TMC prosthesis implantation.

ABSTRACT

Traumatic events increase risk of mental illnesses, but childhood neglect prevalence in psychiatric disorders is understudied. This systematic review and meta-analysis assessed neglect prevalence, including emotional neglect (EN) and physical neglect (PN), among adults with psychiatric disorders. We conducted a systematic search and meta-analysis in 122 studies assessing different psychiatric disorders. Prevalence was 46.6% (95%CI[34.5-59.0]) for unspecified neglect (Ne), 43.1% (95%CI[39.0-47.4]) for EN, and 34.8% (95%CI[30.6-39.2]) for PN. Although a moderating effect of the psychiatric diagnostic category was not confirmed, some clinical diagnoses had significantly lower prevalence rates than others. Patients with bipolar disorder and major depressive disorder showed lower prevalence rates of EN and PN, whereas lower prevalence was found in psychotic disorders and eating disorders for PN only. Neglect assessment was a significant moderator for Ne and PN. No moderating effect of age and sex on neglect prevalence was found. Heterogeneity levels within and between psychiatric diagnostic categories remained high. This is the first meta-analysis examining diverse types of neglect prevalence considering different psychiatric diagnoses. Our results explore the prevalence of childhood neglect and its subtypes among adults with psychiatric disorders, contributing to understanding the nuanced interplay between neglect and specific psychiatric conditions, and guiding interventions for affected individuals.

ABSTRACT

BACKGROUND: Chronic Achilles tendon ruptures (CATR) often require surgical intervention to restore function. Despite numerous treatment modalities available, the optimal management strategy remains controversial given the limited high-quality evidence available. This article aims to provide evidence-based guidelines for the surgical management of CATR through a comprehensive systematic review of the available data. The consensus reached by synthesizing the findings will assist clinicians in making informed decisions and improving patient outcomes. METHODS: A group of 9 foot surgeons in three continents was consulted to gather their expertise on guidelines regarding the surgical management of CATR. Following the proposal of 9 clinical topics, a thorough and comprehensive search of relevant literature published since 1980 was conducted for each topic using electronic databases, including PubMed, MEDLINE, and Cochrane Library, to identify relevant studies published until 1 October 2023. All authors collaborated in drafting, discussing, and finalizing the recommendations and statements. The recommendations were then categorized into two grades: grade a (strong) and grade b (weak), following the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) concept. Additionally, feedback from 21 external specialists, who were independent from the authors, was taken into account to further refine and finalize the clinical guidelines. RESULTS: Nine statements and guidelines were completed regarding surgical indications, surgical strategies, and postoperative rehabilitation protocol. CONCLUSION: Based on the findings of the systematic review, this guideline provides recommendations for the surgical management of CATR. We are confident that this guideline will serve as a valuable resource for physicians when making decisions regarding the surgical treatment of patients with CATR.

ABSTRACT

It is held that the condition of endogenous chronic hypersecretion of cortisol (Cushing syndrome, CS), causes several comorbidities, including cardiovascular and metabolic disorders, musculoskeletal alterations, as well as cognitive and mood impairment. Therefore, CS has an adverse impact on the quality of life and life expectancy of affected patients. What remains unclear is whether disease remission may induce a normalization of the associated comorbid conditions. In order to retrieve updated information on this issue, we conducted a systematic search using the Pubmed and Embase databases to identify scientific papers published from January 1, 2000, to December 31, 2022. The initial search identified 1907 potentially eligible records. Papers were screened for eligibility and a total of 79 were included and classified by the main topic (cardiometabolic risk, thromboembolic disease, bone impairment, muscle damage, mood disturbances and quality of life, cognitive impairment, and mortality). Although the limited patient numbers in many studies preclude definitive conclusions, most recent evidence supports the persistence of increased morbidity and mortality even after long-term remission. It is conceivable that the degree of normalization of the associated comorbid conditions depends on individual factors and characteristics of the conditions. These findings highlight the need for early recognition and effective management of patients with CS, which should include active treatment of the related comorbid conditions. In addition, it is important to maintain a surveillance strategy in all patients with CS, even many years after disease remission, and to actively pursue specific treatment of comorbid conditions beyond cortisol normalization.

ABSTRACT

INTRODUCTION: Computer tomography (CT) based navigation is considered by some authors as an advance in total hip arthroplasty (THA). A meta-analysis was conducted to compare CT based versus conventional THA in terms of surgical duration of the procedure, leg length difference, acetabular cup position, and rate of dislocation. MATERIAL AND METHODS: The present study was conducted according to the PRISMA 2020. In December 2022, the following databases were accessed: PubMed, Web of Science, Google Scholar, Embase with no time constrain. All the clinical studies comparing CT based navigation versus the conventional THA were accessed. RESULTS: Data from 1801 procedures were collected. The mean age of the patients was 61.6 ± 5.3 years, and the mean BMI was 26.9 ± 2.3 kg/m2. There was between studies comparability at baseline in terms of age, BMI, pain score, Harris hip score, leg length discrepancy (P > 0.1). The navigated group demonstrated lower leg length discrepancy (P = 0.02), and lower degrees of cup anteversion (P = 0.002). Similarity was found in cup inclination (P = 0.98), surgical duration (P = 0.3), and the rate of dislocation (P = 0.6). CONCLUSION: CT guided THA may have the potential to increase the accuracy of acetabular positioning and reduce the leg length discrepancy. Current evidence is very limited and heterogeneous, and no recommendations can be inferred. Further investigations are required to definitely clarify the role of CT based THA in current practice.

ABSTRACT

BACKGROUND: Osteoporosis results in reduced bone mass and consequent bone fragility. Small interfering RNAs (siRNAs) can be used for therapeutic purposes, as molecular targets or as useful markers to test new therapies. SOURCES OF DATA: A systematic search of different databases to May 2023 was performed to define the role of siRNAs in osteoporosis therapy. Fourteen suitable studies were identified. AREAS OF AGREEMENT: SiRNAs may be useful in studying metabolic processes in osteoporosis and identify possible therapeutic targets for novel drug therapies. AREAS OF CONTROVERSY: The metabolic processes of osteoporosis are regulated by many genes and cytokines that can be targeted by siRNAs. However, it is not easy to predict whether the in vitro responses of the studied siRNAs and drugs are applicable in vivo. GROWING POINTS: Metabolic processes can be affected by the effect of gene dysregulation mediated by siRNAs on various growth factors. AREAS TIMELY FOR DEVELOPING RESEARCH: Despite the predictability of pharmacological response of siRNA in vitro, similar responses cannot be expected in vivo.

ABSTRACT

Percutaneous repair is a safe and reliable method to restore continuity after acute Achilles tendon ruptures, with a lower incidence of wound complications compared to open techniques. We describe a novel percutaneous cruciate suture performed through 5 stab skin incisions, four of which are longitudinal and parallel to the course of the sural nerve to minimize the risk of injury and one transverse incision at the site of rupture, with a total of 16 suture threads and the knot outside the tendon body, increasing the tensile strength of the suture and minimizing the risk of re-rupture. Clinical studies are necessary to ascertain whether the theoretical advantages of the cruciate suture technique translate into better clinical outcomes compared to established percutaneous techniques.

ABSTRACT

INTRODUCTION: Inside-out and all-inside arthroscopic meniscal repairs are widely performed. However, it remains unclear which method promotes greater clinical outcomes. This study compared inside-out versus all-inside arthroscopic meniscal repair in terms of patient-reported outcome measures (PROMs), failures, return to play, and symptoms. METHODS: This systematic review was conducted in accordance with the PRISMA guidelines. Two authors independently performed the literature search by accessing the following databases: PubMed, Google Scholar, and Scopus in February 2023. All clinical studies which investigated the outcomes of all-inside and/or inside-out meniscal repair were considered. RESULTS: Data from 39 studies (1848 patients) were retrieved. The mean follow-up was 36.8 (9 to 120) months. The mean age of the patients was 25.8 ± 7.9 years. 28% (521 of 1848 patients) were women. No difference was found in PROMs: Tegner Activity Scale (P = 0.4), Lysholm score (P = 0.2), and International Knee Document Committee score (P = 0.4) among patients undergoing meniscal repair with all inside or inside-out techniques. All-inside repairs showed a greater rate of re-injury (P = 0.009) but also a greater rate of return to play at the pre-injury level (P = 0.0001). No difference was found in failures (P = 0.7), chronic pain (P = 0.05), reoperation (P = 0.1) between the two techniques. No difference was found in the rate of return to play (P = 0.5) and to daily activities (P = 0.1) between the two techniques. CONCLUSION: Arthroscopic all-inside meniscal repair may be of special interest in patients with a particular interest in a fast return to sport, while, for less demanding patients, the inside-out suture technique may be recommended. High-quality comparative trials are required to validate these results in a clinical setting. LEVEL OF EVIDENCE: Level III, systematic review.

ABSTRACT

BACKGROUND: Chronic low back pain, common from the sixth decade, negatively impacts the quality of life of patients and health care systems. Recently, mesenchymal stem cells (MSCs) have been introduced in the management of degenerative discogenic pain. The present study summarizes the current knowledge on the effectiveness of MSCs in patients with discogenic back pain. SOURCES OF DATA: We performed a systematic review of the literature following the PRISMA guidelines. We searched PubMed and Google Scholar database, and identified 14 articles about management of chronic low back pain with MSCs injection therapy. We recorded information on type of stem cells employed, culture medium, clinical scores and MRI outcomes. AREAS OF AGREEMENT: We identified a total of 303 patients. Ten studies used bone marrow stem cells. In the other four studies, different stem cells were used (of adipose, umbilical, or chondrocytic origin and a pre-packaged product). The most commonly used scores were Visual Analogue Scale and Oswestry Disability Index. AREAS OF CONTROVERSY: There are few studies with many missing data. GROWING POINTS: The studies analysed demonstrate that intradiscal injections of MSCs are effective on discogenic low-back pain. This effect may result from inhibition of nociceptors, reduction of catabolism and repair of injured or degenerated tissues. AREAS TIMELY FOR DEVELOPING RESEARCH: Further research should define the most effective procedure, trying to standardize a single method.

ABSTRACT

BACKGROUND: We determined whether autologous mesenchymal stem cells (MSCs) injections provide clinical and functional improvements in knee osteoarthritis (KOA) patients, and whether the results differ between autologous bone marrow cells (BMAC) and adipose-derived stromal cells (ADSCs). METHODS: Between January 2021 and April 2022, 51 patients undergoing intra-articular injection of BMAC and 51 patients undergoing intra-articular injection of ADSCs were prospectively recruited. The Kellgren and Lawrence (K-L) classification was used to grade the severity of osteoarthritis. Knee Injury and Osteoarthritis Outcome Score (KOOS), Oxford Knee Score (OKS), and visual analog scale (VAS) were collected for all 102 patients in the previous week before the procedures, and at the one and 6 months from injection. RESULTS: Knee KOOS scores, knee OKS scores, and VAS pain scores changed in similar ways in the two treatment groups. Both treatment groups demonstrated significant improvement pre-procedure to post-procedure in knee KOOS scores (p < 0.0001), knee OKS scores (p < 0.0001), and VAS pain scores (p < 0.0001). Patients with K-L grade 2 showed better functional and clinical outcomes than patients with K-L grades 3 and 4 (p < 0.0001). CONCLUSION: Both intra-articular BMAC and ADSC injections significantly improved pain and functional outcomes at 6-month follow-up in patients with KOA. The difference between BMAC and ADCSs groups as tissue sources of MSCs was not statistically significant in terms of clinical and functional outcomes.

ABSTRACT

Ruptures of the quadriceps tendon (QTRs) are uncommon. If the rupture is not diagnosed, chronic ruptures may develop. Re-ruptures of the quadriceps tendon are rare. Surgery is challenging because of tendon retraction, atrophy and poor quality of the remaining tissue. Multiple surgical techniques have been described. We propose a novel technique in which the quadriceps tendon is reconstructed using the ipsilateral semitendinosus tendon.

ABSTRACT

PURPOSE: After four weeks from injury, tears of the Achilles tendon are considered chronic. Their management is challenging, and the use of a graft is suggested when the gap between proximal and distal stumps is greater than 6 cm. The present study systematically reviews the outcome of free tendon grafts in chronic ruptures of the Achilles tendon, evaluating clinical outcomes, complications and return to sport. METHODS: The present study was conducted according to the PRISMA 2020 guidelines. PubMed, Google Scholar, Embase, and Web of Science databases were accessed in February 2023. All the published clinical studies reporting clinical outcome, return to sport and complications of free tendon grafts used the treatment of chronic rupture of the midportion of the Achilles Tendon were accessed. The mean CMS (Coleman Methodology Score) of 65.7 suggested an overall good quality of the available published articles, attesting to the low risk of bias. RESULTS: Data from 22 articles (368 patients with a mean age of 47 years) were retrieved. The average time from rupture to surgery was 25.1 week. At last follow-up, the AOFAS (American Orthopaedic Foot and Ankle Surgery) and ATRS (Achilles Tendon Total Rupture Score) scores improved of 33.8 (P = 0.0004), and 45.1 points (P = 0.0001) respectively. Return to activity was reported in 105 patients, and 82 (78.1%) had no activity limitations, while 19 (18.1%) had limited recreational but not daily activity limitations, and 4 (3.8%) reported limitations in daily activities. Return to sport data was reported in six studies, and 45 of 93 (48.4%) patients returned to sport at an average of 22.6 weeks. CONCLUSION: In chronic tears of the Achilles tendon, with a gap of at least 6 cm, free tendon grafts allow predictable return to sport and acceptable recovery function. LEVEL OF EVIDENCE: Level IV.

ABSTRACT

The current literature has mainly focused on the biology of tendons and on the characterization of the biological properties of tenocytes and tenoblasts. It is still not understood how these cells can work together in homeostatic equilibrium. We put forward the concept of the "tendon unit" as a morpho-functional unit that can be influenced by a variety of external stimuli such as mechanical stimuli, hormonal influence, or pathological states. We describe how this unit can modify itself to respond to such stimuli. We evidence the capability of the tendon unit of healing itself through the production of collagen following different mechanical stimuli and hypothesize that restoration of the homeostatic balance of the tendon unit should be a therapeutic target.

ABSTRACT

BACKGROUND: Tendon xanthomatosis is often associated with familial hypercholesterolemia, but it can also occur in other medical conditions. The Achilles tendon is the most common site of tendon xanthomas. Reconstruction of large defects after the xanthoma excision, can be challenging. METHODS: We propose a novel technique for Achilles tendon reconstruction with the use of an ipsilateral autologous semitendinosus tendon graft. The technique consists of six steps. RESULTS: This procedure has a low rate of complications and provides results that are at least comparable with those reported with other surgical approaches.

ABSTRACT

PURPOSE: All-inside anterior talofibular ligament (ATFL) repair using anchors is frequently used to manage chronic lateral ankle instability (CLAI) with satisfactory functional outcomes. It remains unclear whether there are differences in the functional results between the use of one or two double-loaded anchors. METHODS: This retrospective cohort study included 59 CLAI patients who underwent an all-inside arthroscopic ATFL repair procedure from 2017 to 2019. Patients were divided into two groups according to the number of anchors used. In the one-anchor group (n = 32), the ATFL was repaired with one double-loaded suture anchor. In the two-anchors group (n = 27), the ATFL was repaired with two double-loaded suture anchors. At the last follow-up time point, the Visual Analogue Scale (VAS) scores, American Orthopedic Foot and Ankle Society (AOFAS) scores, Karlsson Ankle Function Score (KAFS), Anterior Talar Translation (ATT), Active Joint Position Sense (AJPS), and the rate of return to sports in both groups were compared. RESULTS: All the patients were followed up for at least 24 months. Improvement in the functional results (VAS, AOFAS, KAFS, ATT, and AJPS) were recorded at the final follow-up time point. No significant differences were observed regarding VAS, AOFAS, KAFS, ATT, and AJPS between the two groups. CONCLUSION: In patients with CLAI undergoing all-inside arthroscopic ATFL repair, the use of either one or two double-loaded suture anchors produces comparable and predictably good functional outcomes. LEVEL OF EVIDENCE: Level III.
