The aim of this systematic review is to determine the effectiveness on functional and pain outcomes of different exercise protocols as a conservative treatment for massive, irreparable rotator cuff tears in elderly patients. A literature search was carried out consulting Pubmed -Medline, Cochrane central and Scopus to select randomized clinical trials, prospective and retrospective cohort studies or case series, that evaluated functional and pain outcomes after physical therapy in patients aged 65 or over, affected by massive rotator cuff tears. The present systematic review followed the Cochrane methodology for systematic reviews and the reporting was implemented using through the PRISMA guidelines. The Cochrane risk of bias tool and MINOR score were used for methodologic assessment. Nine articles were included. Data concerning physical activity, functional outcomes and pain assessment were obtained from the included studies. The exercise protocols assessed within the included studies were extremely wide with equally different methods of evaluation of the outcomes. However, most of the studies demonstrated a trend of improvement after the treatment, in terms of functional scores, pain, ROM and quality of life. An intermediate methodological quality of the included papers was assessed through the risk of bias evaluation. Our results showed a positive trend in patients who underwent physical exercise therapy. Our conclusion is that further studies of a high level of evidence are needed to achieve consistent evidence to improve clinical practice in the future.

Total Hip Arthroplasty (THA) may be performed through various approaches; however, depending on the surgical position of the patient, the superiority of lateral or supine position is still debated. The aim of this systematic review and meta-analysis was to compare the supine versus lateral position in THA in terms of intraoperative and postoperative outcomes and component placement. The systematic literature search was performed by the use of Cochrane Central, Pub-Med–Medline, and Google Scholar in order to select studies that evaluated clinical outcomes and the outliers of cup alignment for inclination and anteversion between supine and lateral position for hip arthroplasty. Finally, 9 articles were included in this review. The meta-analysis showed no significant differences between the two groups for clinical outcomes, unless for blood loss and VAS (respectively p = 0.05 and p = 0.004 in favour of lateral decubitus). Regarding the number of outliers, the supine decubitus showed significant differences only for the cup anteversion (p = 0.01). However, more prospective studies with a longer follow-up that analyze both clinical and radiological parameters are needed to assess the superiority of supine or lateral patient position for total hip arthroplasty.

In countries with a high average population age, total knee arthroplasty is still carried out in an inpatient setting. The roadmap to performing major surgery on an outpatient basis passes through the understanding of those perioperative features that correlate with higher lengths of hospital stay (LOS). A retrospective database of 1200 patients was reviewed for retrieving preoperative and perioperative factors including anthropometric and demographic data, comorbidities, preoperative laboratory assessment, and surgical time. Considering the LOS as a discrete series, data were analyzed by means of logistic regression with multiple univariate and multivariate models. The results showed a median length of hospital stay of 3 (IQR 3, 4) days. According to multiple univariate analysis, arterial hypertension (p = 0.008), diabetes mellitus (p = 0.028), CCI score (p < 0.001), ASA score (p = 0.006), surgical time (p < 0.001) and intraoperative blood loss (p < 0.001) were significantly associated with the duration of hospital stay in days. Moreover, preoperative hemoglobin value was inversely correlated to the LOS (p = 0.008). Multivariate analysis showed a significant correlation between LOS and surgical time and intraoperative blood loss. Many factors influence the permanence of the inpatient and acting on those variables, by stabilizing comorbidities and optimizing laboratory values, may reduce the overall healthcare burden.

The aim of this retrospective investigation is to evaluate the correlation between several preoperative and perioperative factors and the length of hospital stay in patients that underwent elective total hip arthroplasty with overnight admission. Medical records of patients that underwent THA from the beginning of 2016 to the end of 2018 were retrospectively screened. Demographics, comorbidities, whole blood count, intraoperative details, and length of postoperative stay were retrieved. The association between clinical, laboratory and surgical factors and the length of hospital stay was explored by means of negative binomial and logistic regression models. The median length of postoperative hospital stay was four days (Inter Quartile Range, IQR 3, 5). After univariate regression a stepwise multivariate regression showed that operative time (p = 0.001), the preoperative serum creatinine (p &lt, 0.001), the intraoperative blood loss (p = 0.04) and the use of an anterolateral approach (p &lt, 0.001) were found to correlate significantly with the increase of the hospitalization length, while no significant correlation was found for all the other features. Multivariable model fitted through logistic regression (LOS below or over the median value of four days) had an Area Under the Curve (AUC) of 0.748. Our analysis suggests a significant role played by different preoperative and perioperative variables in influencing the length of hospital stay.

Thanks to modern surgical techniques and implants, traditional exclusion criteria for unicompartmental knee arthroplasty (UKA) are no longer considered contraindications. The aim of this study is to clarify the impact of obesity on functional outcomes and revision rates of UKA. We performed a comprehensive systematic review using PubMed–Medline, Google Scholar and Cochrane Central. Then, we extracted data related to body mass index (BMI), age and follow-up, functional outcome scores and rate of revisions (all-cause, aseptic and septic). Patients were stratified according to BMI into two groups: non-obese (BMI < 30) and obese (BMI ≥ 30). We identified 22 eligible studies, of which 13 were included in the meta-analysis. Patients with a BMI > 30 had a significantly higher likelihood for revision (p = 0.02), while the risk of septic revision was similar (p = 0.79). The clinical outcome measures showed a significant difference in favor of patients with a BMI < 30 (p < 0.0001). The improvements in Oxford Knee Score and Knee Society Score were significant in both obese and non-obese patients, although the latter showed inferior results. The results of this systematic review and meta-analysis show that BMI is not a contraindication to UKA. However, obese patients have a higher risk for aseptic failure and lower improvement in clinical scores compared to non-obese patients.

Chronic low back pain (CLBP) affects nearly 20–25% of the population older than 65 years, and it is currently the main cause of disability both in the developed and developing countries. It is crucial to reach an optimal management of this condition in older patients to improve their quality of life. This review evaluates the effectiveness of physical activity (PA) to improve disability and pain in older people with non-specific CLBP. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines were used to improve the reporting of the review. Individual risk of bias of single studies was assessed using Rob 2 tool and ROBINS-I tool. The quality of evidence assessment was performed using GRADE analysis only in articles that presents full data. The articles were searched in different web portals (Medline, Scopus, CINAHL, EMBASE, and CENTRAL). All the articles reported respect the following inclusion criteria: patients > 65 years old who underwent physical activities for the treatment of CLBP. A total of 12 studies were included: 7 randomized controlled trials (RCT), 3 non-randomized controlled trials (NRCT), 1 pre and post intervention study (PPIS), and 1 case series (CS). The studies showed high heterogeneity in terms of study design, interventions, and outcome variables. In general, post-treatment data showed a trend in the improvement for disability and pain. However, considering the low quality of evidence of the studies, the high risk of bias, the languages limitations, the lack of significant results of some studies, and the lack of literature on this argument, further studies are necessary to improve the evidences on the topic.

In the scientific landscape, there is a growing interest in defining the role of several biomolecules and humoral indicators of the aging process and in the modifications of these biomarkers induced by physical activity and exercise. The main aim of the present narrative review is to collect the available evidence on the biohumoral indicators that could be modified by physical activity (PA) in the elderly. Online databases including Pubmed, Web of science (Medline), and Scopus were searched for relevant articles published in the last five years in English. Keywords and combination of these used for the search were the following: “biological”, “indicators”, “markers”, “physical”, “activity”, and “elderly”. Thirty-four papers were analyzed for inclusion. Twenty-nine studies were included and divided into four categories: cardiovascular (CV) biomarkers, metabolic biomarkers, inflammatory markers-oxidative stress molecules, and other markers. There are many distinct biomarkers influenced by PA in the elderly, with promising results concerning the metabolic and CV indexes, as a growing number of studies demonstrate the role of PA on improving parameters related to heart function and CV risk like atherogenic lipid profile. Furthermore, it is also a verified hypothesis that PA is able to modify the inflammatory status of the subject by decreasing the levels of pro-inflammatory cytokines, including interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α). PA seems also to be able to have a direct effect on the immune system. There is a strong evidence of a positive effect of PA on the health of elderly people that could be evidenced and “quantified” by the modifications of the levels of several biohumoral indicators.

This systematic review aimed to investigate the clinical and functional outcomes and complication rate of simultaneous anterior cruciate ligament reconstruction (ACLR) and unicompartmental knee arthroplasty (UKA). A systematic search in PubMed–Medline, Cochrane Library, and Google Scholar was carried out to identify eligible randomized clinical trials, observational studies, or case series that reported on clinical and functional results of combined ACLR and UKA in adults with a unicompartmental knee osteoarthritis and ACL deficiency. Four retrospective studies and three prospective studies were included in this review. A total of 169 patients were included with a mean follow-up of 6.3 years. The Mean Oxford Knee Score improved from 29.4 to 43.9 at the final follow-up. All the other reported scores significantly improved after surgery. The overall revision rate was 3.5%. The MINORS score ranged from 8 to 14. Association analysis of MINORS score and year of publication, through Pearson’s coefficient, showed no significant association (p = −0.089). Simultaneous ACLR and UKA is a safe procedure with a significant postoperative improvement of functional and clinical outcomes for patients with ACL injury that complain of knee instability and isolated medial compartment pain.

The aim of this systematic review and meta-analysis was to evaluate the rate of return to sport in elderly patients who underwent anatomic (ATSA) and reverse (RTSA) total shoulder arthroplasty, to assess postoperative pain and functional outcomes and to give an overview of postoperative rehabilitation protocols. A systematic search in Pubmed-Medline, Cochrane Library, and Google Scholar was carried out to identify eligible randomized clinical trials, observational studies, or case series that evaluated the rate of return to sport after RTSA or ATSA. Six retrospective studies, five case series, and one prospective cohort study were included in this review. The overall rate of return to sport was 82% (95% CI 0.76–0.88, p < 0.01). Patients undergoing ATSA returned at a higher rate (90%) (95% CI 0.80–0.99, p < 0.01) compared to RTSA (77%) (95% CI 0.69–0.85, p < 0.01). Moreover, the results showed that patients returned to sport at the same or a higher level in 75% of cases. Swimming had the highest rate of return (84%), followed by fitness (77%), golf (77%), and tennis (69%). Thus, RTSA and ATSA are effective to guarantee a significative rate of return to sport in elderly patients. A slightly higher rate was found for the anatomic implant.

Orthopedic sports medicine is a subspecialty of Orthopedics that focuses on managing pathological conditions of the musculoskeletal system arising from sports practice. When dealing with athletes, timing is the most difficult issue to face. Typically, athletes aim to return to play as soon as possible and at the pre-injury level. This means that management should be optimized to combine the need for prompt return to sport and to the biologic healing time of the musculo-skeletal. This poses a great challenge to sport medicine surgeons, who need to follow with attention to the latest scientific evidence to offer their patients the best available treatment options. We briefly review the most commonly performed orthopedic sports medicine procedures, outlining the presently available scientific evidence on their indications and outcomes.

Purpose The alignment at the cervical spine has been considered a determinant of degeneration at the adjacent disc, but this issue in cervical disc replacement surgery is poorly explored and discussed in this patient population. The aim of this systematic review is to compare anterior cervical fusion and total disc replacement (TDR) in terms of preservation of the overall cervical alignment and complications.Methods A systematic review of the current literature was performed, together with the evaluation of the methodological quality of all the retrieved studies.Results In most of the retrieved studies, a tendency towards a more postoperative kyphotic alignment in TDR was reported. The reported mean complication rate was of 12.5 % (0-66.2 %). Complications associated with cervical prosthesis included heterotopic ossification, device migration, mechanical instability, failure, implant removal, reoperations and revision.Conclusions Even though cervical disc arthroplasty leads to similar outcomes compared to arthrodesis in the middle term follow-up, no evidence of superiority of cervical TDR is available up to date. We understand that the overall cervical alignment after TDR tends towards the loss of lordosis, but only longer follow-up can determine its influence on the clinical results.

The aim of this review is to collect and discuss the current best evidence published in literature about the effect of the Masai Barefoot Technology(MBT) shoes on gait and muscle activation and try to draw conclusions on the possible benefits. We searched Medline, CINAHL, Embase and the Cochrane Central Registry of Controlled Trials. The reference lists of the previously selected articles were then examined by hand. Only studies comparing biomechanical and clinical outcomes were selected. Review, anatomical studies, letter to editor and instructional course were excluded. Finally, all the resulting articles were reviewed and discussed by all the authors to further confirm their suitability for this review: in the end, 22 articles were included. A total of 532 patients presenting a mean age of 34.3 years were studied. All patients evaluated were healthy or amateur sports except in two studies where only obese subjects and knee osteoarthritis patients were involved. Seven studies evaluated only male subjects, whereas four studies evaluated only female. Twelve of twenty-two studies performed electromyographic analyses. Weight was reported in 19 studies, whereas body mass index were reported only in a five studies. All studies reported kinematic analysis of shoe effects and compared the relationship between muscle recruitment and electromyographic activity. Unstable footwears were shown to immediately alter the stability in gait during daily-life activities. The center of body pressure is moved posteriorly with a consequent posterior displacement of the upper part of body in order to regain an appropriate body balance, and these postural changes are associated with an overall increase in the activity of lumbar erector spine muscles, as well as certain lower limb muscles. Current literature provides enough cues to conclude for a beneficial role of MBT shoes in the postural and proprioceptive recovery, but from the same literature cannot be drown clear and appropriate guidance to determine more in detail their indication for specific pathological conditions or for particular phases of the musculoskeletal recovery process.

To overview the complications involving extensor apparatus of the knee following total knee arthroplasty (TKA) and to summarize which are the lines of treatment available and their reported outcomes in literature. A comprehensive search of several databases was performed using as basic keywords “complications after TKA”, “extensor mechanism disruption”, “periprosthetic patellar fracture”, “quadriceps tendon rupture”, “quadriceps tendon rupture” isolated or combined with other terms by using Boolean operators. The methodological quality of each article was also evaluated using the Coleman methodology score (CMS). Twenty-nine studies were evaluated. The mean CMS of the studies selected was 33.1/100. Patellar fractures, requiring surgical treatment when there is rupture of the extensor mechanism or loosening of the patellar component, were treated surgically in 28.1 % of patients. The patellar and quadriceps tendon ruptures were surgically treated with reconstruction or augmented repair, respectively, in 98.6 and 76.5 %. Complications involving the extensor apparatus of the knee following a TKA need early and appropriate management to avoid their devastating influence on joint functionality. Management has to be evaluated very carefully based on the site of the lesion, integrity of the prosthetic components and surrounding tissue to restore, and the patients’ individual characteristics. The surgical approach for comminuted periprosthetic fractures and reconstruction of torn tendons of the extensor apparatus are needed to restore function and decrease pain, but, given the poor methodological quality of the studies published so far, it is not clear which surgical technique or graft leads to better outcomes. Therefore, there is an absolute need for better designed comparative trials producing clearer and stronger evidence on this critical matter. IV.

Symptomatic tendon tears are one of the most important causes of pain and joint dysfunction. Among the intrinsic causes, vascularization recently gained a major role. Endothelial function is indeed a key factor, as well as vascular tone and thrombotic factors, in the regulation of vascular homeostasis and the composition of vascular wall. In this review, we studied systematically whether there is a relationship between endothelial dysfunction and tendinopathy. A literature search was performed using the isolated or combined keywords endothelial dysfunction and tendon,' 'nitric oxide (NO) and tendinopathy,' and 'endothelial dysfunction in tendon healing.' We identified 21 published studies. Of the selected studies, 9 were in vivo studies, 2 focusing on animals and 7 on humans, while 12 reported about in vitro evaluations, where 7 were carried out on humans and 5 on animals. The evidence about a direct relationship between tendinopathy and endothelial dysfunction is still poor. As recent studies have shown, there is no significant improvement in clinical and functional assessments after treatment with NO in patients suffering from tendinopathy in different locations. No significant differences were identified in the outcomes reported for experiment group when compared with controls treated with conventional surgical procedures or rehabilitation programs. Nitric oxide could be a marker to quantify the response of the endothelium to mechanical stress or hypoxia indicating the final balance between vasodilatating and vasoconstricting factors and their effects, but more ad stronger evidence is still needed to fully support this practice.

Introduction: Multiple Myeloma (MM) typically involves the spine and causes bone pain, pathological fractures and spinal cord compression with possible consequent neurological deficits. This retrospective study reports the results of surgery on a selected population of patients who underwent surgery for symptomatic spinal myeloma.Materials and methods: A total of 26 patients who underwent surgery for spinal myeloma with neurological involvement were studied retrospectively. Neurological evaluation was performed according to the Frankel grade. Characteristics of this population, reconstructive techniques and surgery-related complications were reviewed.Results: The tumours involved the thoracic spine in 13 patients, the lumbar spine in 10 patients, and the cervical spine in three patients. The most common approach was a posterior-only approach (70%), followed by a staged, combined approach (20%), and an anterior-only approach (10%). The mean postoperative survival time was 43 months (range: 8-60 months). A significant improvement in neurological function was observed in the study population after surgery (p = 0.001). There were seven early postoperative complications, two late complications and five surgery-related complications.Discussion: Surgery in selected patients affected by spinal myeloma with neurological involvement is associated with good clinical outcomes and neurological recovery and an acceptable rate of complications. Neurological deficit and segmental instability can be treated sufficiently in most cases by the implementation of a posterior-only approach; however, the final treatment should, when possible, include adjuvant chemotherapy and radiotherapy and rigorous bracing.

Background and purpose Osteomyelitis (OM) is considered one of the most challenging medical conditions an orthopaedic surgeon has to face. Much debate is present concerning diagnosis and treatment, especially about differences between acute and chronic forms of the condition. The main aim of the present work is to show the key points where research should be implemented. Methods Online database were searched to find evidence about the clinical management of osteomyelitis. Clinical randomized trials, case series, prospective cohort studies reporting on diagnosis and treatment of acute and chronic osteomyelitis were taken into consideration. Cadaveric studies, laboratory studies, case reports, review articles and meta-analyses were excluded. Furthermore, studies concerning implant related OM were excluded. Studies in English, Spanish and French were considered in this process of inclusion. The cohorts of all the included studies were composed of adult patients. Results The main growpoints concerning OM are the identification of a correct laboratory test array to allow a prompt diagnosis and provide a sensitive and specific detection of the bacterial species involved, along with antibiotic drug resistance; optimal imaging techniques, according to the phase of the infection, have to be performed, to avoid unnecessary medical expenses; the identification of a suitable compromise between intravenous and oral drugs administration. A flow chart is proposed for optimal clinical management of this pathology. Conclusion More work should be carried out to clarify the main issues concerning the clinical management of osteomyelitis in adult patients.

The aim of this review is to evaluate the clinical role of sarcopenia in patients affected by osteoarthritis (OA) of major joints.An online database research was performed, in order to retrieve all articles investigating the relationship between sarcopenia and OA. No peer-reviewed journal was excluded. Papers in English, French, Spanish and Italian language were considered. After consulting the full-text article, five studies have been included in the review.Of the five studies included, four are prospective studies and only one is a cross-sectional study which retrieved data retrospectively. A total of 4,231 patients, presenting a mean age of 62.0 years, were studied. Three studies evaluated only female subjects. Weight, height and body mass index were reported in all the articles. Knee OA has been assessed using the Kellgren-Lawrence grading system and the American college of rheumatology criteria. Alterations of the lean body mass on body weight ratio have been reported to be as a significant predictive parameter in two studies. Relationship between radiographic OA and an increase in the leg lean mass has been observed in one study.We cannot support neither the thesis of a direct effect of sarcopenia on OA development nor the opposite relation, because the up-to-date literature lacks basic science studies concerning these topics. The absence of clinical studies regarding measurements and tools to compare sarcopenia and OA do not allow to definitely clarify this relationship.
