Abstract
The purpose of this study was to determine if women footballers have an increased lack of neuromuscular control of the knee joint after a concussion compared to a healthy cohort tested with tensiomyography (TMG). Forty-one female collegiate footballers were enrolled in this study from which there were 20 with a history of sports-related concussions (SRCs) and 21 control subjects. Results from the SRC group had significantly higher Tc (ms) (z = -5.478, p = 0.000) and significantly lower Dm (mm) (z = -3.835, p = 0.000) than the control group in the case of the rectus femoris muscle. The SRC group had significantly higher Tc (ms) (z = -2.348, p = 0.016) and significantly lower Dm (mm) (z = -4.776, p = 0.000) than the control group in the case of the vastus medialis muscle. The SRC group had significantly higher Tc (ms) (z = -5.400, p = 0.000) and significantly lower Dm (mm) (z = -4.971, p = 0.000) than the control group in the case of the vastus lateralis muscle. The SRC group had significantly higher Tc (ms) (z = -5.349, p = 0.000) than the control group in the case of the biceps femoris muscle response, whereas no significant difference was found in Dm (mm) (z = -0.198, p = 0.853) between the groups. The results of the current study may have implications for current practice standards regarding the evaluation and management of concussions and can add valuable information for knee prevention programs as well.

Abstract
INTRODUCTION This systematic review aims to critically assess the literature comparative studies investigating collared and collarless Corail stem in primary total hip arthroplasty (THA) to find differences in revision rates, radiographic and clinical outcomes, and postoperative complications between these two types of the same stem. METHODS Eligible studies were found by searching PubMed, Science Direct/Scopus, and the Cochrane Database of Systematic Reviews from conception till May 2023. The PRISMA guidelines were followed. The investigation encompassed randomized controlled trials, case series, comparative, cohort, and observational studies that assessed at least one comparative outcome or complication between collared and collarless Corail stems. RESULTS Twelve comparative studies with 90,626 patients undergoing primary THA were included. There were 40,441 collared and 58,543 collarless stems. The follow-up ranged from 12 to 360 months. Our study demonstrated no significant difference in stem revision relative risk (RR = 0.68; 95% confidence interval (CI), 0.23, 2.02; p = 0.49), number of radiolucent lines (RR = 0.3; 95% CI, 0.06, 2.28; p = 0.29) and overall complication risk (RR = 0.62; 95% CI, 0.22, 1.76; p = 0.37) between collared and collarless stems. The collared stems demonstrated significantly lesser subsidence (mean difference: 1.01 mm; 95% CI, -1.77, -0.25; p = 0.009) and risk of periprosthetic fractures (RR = 0.52; 95% CI, 0.29, 0.92; p = 0.03). CONCLUSION The comparative studies between collared and collarless stem groups showed similar survival and overall complication rates and functional outcomes. The similar revision rates between groups make the impact of higher subsidence for collarless stems uncertain. The lower risk of periprosthetic fractures in the collared stems group must be clarified further but could be related to increased rotational stability.

Abstract
BACKGROUND Muscle fatty degeneration following rotator cuff tears has been unequivocally associated with poorer functional outcomes and increased risk for retear following rotator cuff repair. Promising results have emerged from animal studies, with the implementation of various interventions for biologic inhibition of this fatty muscle degeneration. The lack of high quality randomized human evidence on this topic, increases the impact of pooled results from animal literature. The aim of the present study was to systematically review the available published literature for animal studies evaluating the ability of several interventions used to mitigate muscle fatty degeneration following the repair of massive rotator cuff tears. PATIENTS AND METHODS A comprehensive search was conducted on Pubmed, Scopus and Google Scholar, covering the period from conception until 16th April 2022. Datasets were stratified based on the type of intervention performed. SYRCLE risk of bias instrument was implemented for quality assessment of the included studies. RESULTS Rotator cuff repair augmentation with Adipose derived stem cells (ADSC's), Mesenchymal stem cells (MSC's) and Nandrolone was effective against fatty infiltration, but less effective against muscle atrophy. More beneficial effect was shown by the utilization of Beige adipose tissue - Fibroadipogenic progenitors (BAT-FAP) stimulation, using either Amibregon or BAT-FAPs transplantation. Both provided good results in mitigating muscle atrophy, fatty infiltration and fibrosis. DISCUSSION ADSC's, MSC's, Nandrolone and BAT-FAP stimulation may have a role in mitigating muscle fatty degeneration following rotator cuff tears. Large scale human studies are required to further elucidate their role in the clinical setting. LEVEL OF EVIDENCE V; systematic review of pre-clinical studies.

Abstract
PURPOSE Four joint arthroplasty registries (JARs) levels exist based on the recorded data type. Level I JARs are national registries that record primary data. Hospital or institutional JARs (Level II-IV) document further data (patient-reported outcomes, demographic, radiographic). A worldwide list of Level II-IV JARs must be created to effectively assess and categorize these data. METHODS Our study is a systematic scoping review that followed the PRISMA guidelines and included 648 studies. Based on their publications, the study aimed to map the existing Level II-IV JARs worldwide. The secondary aim was to record their lifetime, publications' number and frequency and recognise differences with national JARs. RESULTS One hundred five Level II-IV JARs were identified. Forty-eight hospital-based, 45 institutional, and 12 regional JARs. Fifty JARs were found in America, 39 in Europe, nine in Asia, six in Oceania and one in Africa. They have published 485 cohorts, 91 case-series, 49 case-control, nine cross-sectional studies, eight registry protocols and six randomized trials. Most cohort studies were retrospective. Twenty-three per cent of papers studied patient-reported outcomes, 21.45% surgical complications, 13.73% postoperative clinical and 5.25% radiographic outcomes, and 11.88% were survival analyses. Forty-four JARs have published only one paper. Level I JARs primarily publish implant revision risk annual reports, while Level IV JARs collect comprehensive data to conduct retrospective cohort studies. CONCLUSIONS This is the first study mapping all Level II-IV JARs worldwide. Most JARs are found in Europe and America, reporting on retrospective cohorts, but only a few report on studies systematically.

Abstract
Purpose The main indication of bisphosphonates (BPs) is osteoporosis treatment. However, there is growing interest in the peri- and postoperative use of BPs to mitigate total hip arthroplasty (THA) aseptic loosening (AL) risk. This systematic review aimed to evaluate the implant survival and the AL rate in patients with elective THA receiving BPs compared to those that do not receive BPs. Secondary outcomes included the comparison of revision rate, postoperative complications, and patients' functional scores. Methods This systematic review was conducted under the PRISMA 2020 guidelines with a pre-registered PROSPERO protocol. Three engines and grey literature were searched up until May 2022. Randomized and nonrandomized controlled trials and comparative cohort studies assessing BP and control therapy impact on THA survival were included. Results Twelve studies embraced the inclusion criteria. A total of 99 678 patients and 99 696 THAs were included; 10 025 patients received BPs (BP group), and 89 129 made up the control group. The overall revision and AL rates were lower in the BP group (2.17% and 1.85%) than in the control group (4.06% and 3.2%). Periprosthetic fracture (PPF) cases were higher in the BP group (0.24%) than in the control group (0.04%); however, the majority of PPF cases were derived from a single study. Further complication risk was similar between groups. Most studies reported comparable functional scores between groups. Conclusion BP treatment after elective THA seems to reduce the overall revision and AL risk. Other complications' risk and functional scores were similar between groups. Further high-quality studies are needed to validate the results due to the multifactorial AL pathogenesis.

Abstract
Background Soccer is unique among sports because it is the only sport that involves purposeful use of the head to control, pass, or shoot the ball. Over the previous five years, a relationship between lower extremity (LE) injury and sports related concussion (SRC) has been established in various sporting populations. Athletes at the high school, collegiate, and professional levels have demonstrated a greater risk for sustaining a LE injury post SRC. The purpose of this systematic review was to examine the relationship of the SRC with the incidence of LE injuries. Methods Ten databases were searched with the following keywords: Lower limb, ball heading, neuromuscular control, concussion, MEDLINE, Ovid MEDLINE(R) Daily, and Ovid MEDLINE(R), EMBASE, and Scopus. The search was limited to English-language and peer-reviewed publications, until 15/12/2022. The PEDro scale was used for the assessment of the risk of bias among the included studies. All included papers were qualitatively analyzed. Results A total of 834 studies were identified and 10 articles (four concussion-MSK biomechanics, six concussion-MSK injury) were included in the qualitative analyses. Included papers ranged from low to high quality. Due to the heterogeneous nature of the included study designs, quantitative meta-analysis was unable to be performed. All four of the included concussion-MSK biomechanics studies demonstrated, to some degree, that worse cognitive performance was associated with lower extremity MSK biomechanical patterns suggestive of greater risk for MSK injury. Among the six injury related studies, two investigations failed to determine group differences in cognitive performance between subsequently injured and non-injured athletes. Conclusion More research is needed to better understand the relationship of SRC and lower extremity injuries and the extent to which they are related to concussions and/or repetitive neurotrauma after ball heading sustained in soccer. Level of Evidence 2.

Abstract
Background This comprehensive systematic review aims to assess the literature regarding the risk of postoperative complications in patients undergoing total joint arthroplasty (TJA) with concomitant thyroid dysfunction. Methods Studies were identified by searching PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, and ClinicalTrials.gov (end of search: May 2022). Inclusion criteria Randomized control and case-control studies, cohort and observational clinical studies were included, which focused on postoperative complications and outcomes of patients undergoing TJA operations of major joints (knee, hip, ankle, elbow). All studies were assessed according to their level of evidence, the number and age of patients, and treatment complications. Analysis Nine studies were included in this review that demonstrated a higher risk of postoperative anemia, perioperative blood loss, hemoglobin decrease, and transfusion rates in hypothyroid patients after TJA. Results Hypothyroidism has been identified as a potential but modifiable risk factor for increased rates of deep venous thrombosis, acute kidney injury, pneumonia, and non-specified cardiac complications among hypothyroid patients who underwent TJA as well as increased rates of periprosthetic joint infection. No significant differences in the prosthesis-related mechanical complication rates have been calculated when comparing hypothyroid and euthyroid patients.

Abstract
BACKGROUND The outcomes of constrained liners (CLs) in total hip arthroplasty (THA) remain inconclusive. We evaluated the mid-term performance of CLs in a consecutive series of high-risk dislocation patients undergoing primary or revision THA performed by a single surgeon. The survival, dislocation rate, complications, and functional patients' scores were assessed. Surgical tips to enhance outcomes were reviewed. METHODS 45 patients who received the Trident Tripolar CL between 2010 to 2019 were retrospectively evaluated from Arthroplasty Registry Thessaloniki. There were 17 primary and 28 revision THAs. The primary indications for using CL were severe abductor insufficiency or comorbidities, increasing the dislocation risk in primary, and recurrent dislocation or abductor insufficiency in revision THAs. The mean patient's age was 68.5 (±14.5) years, and the mean follow-up 3.81 (±1.66) years. RESULTS There were 2 dislocations and 1 deep infection in the revision group. For any reason, the cumulative 6-year survival rate was 93.3%, 100% for primary, and 89.3% for revision THAs. The mean overall CL survival was 76.3 months for any reason (95% CI, 68.1-84.5) and 80.5 months for dislocation (95% CI, 75.8-85.2). The mean postoperative functional scores were significantly improved (p < 0.001) at the latest follow-up. CONCLUSIONS CLs can provide hip stability and durable fixation in selected low-demand patients with high-risk for dislocation after primary and revision THA at mid-term follow-up. Careful patient selection and the refined surgical technique aiming at the neutral liner position and considering the high CLs' offset relative to stem-neck impingement are necessary to maximise outcomes.

Abstract
INTRODUCTION The Direct Superior Approach (DSA) is a muscle-sparing hip approach that does not protect the piriformis and the other short external rotators. We present a DSA modification we named STAR (Superior Transverse Atraumatic Reconstruction), which has DSA advantages but always preserves piriformis. Our study compared the early postoperative, radiological, and functional results of patients undergoing primary total hip arthroplasty (THA) through the STAR approach with a matched DSA group performed by a senior surgeon. METHODS Each group, DSA, and STAR included 200 elective primary unilateral THAs performed by the surgeon between 2016-2017 and 2020-2021, respectively. Patients were included in both groups using the same inclusion criteria. Both groups were matched for age and sex. The same postoperative pain management, chemoprophylaxis, and physiotherapy protocols were followed in both groups. Two independent orthopaedic surgeons performed the clinical and radiological follow-up. RESULTS The STAR group had significantly lower mean incision length (p = 0.042) and hospital stay (p = 0.002) than the DSA group. The mean intraoperative blood loss (p = 0.085) and the need for blood transfusion (p = 0.228) were less for the STAR than the DSA group. The mean postoperative functional scores improvement was significantly higher for the STAR than the DSA group at the end of the first and third postoperative months. CONCLUSIONS The STAR approach offers earlier functional improvement, shorter hospital stay and less transfusion need than DSA for patients undergoing primary THA. Both approaches showed a limited complication risk and an outstanding acetabular and femoral access enabling the procedure.

Abstract
PURPOSE Studies comparing clinical outcomes between manual (mTKA) and robotic-assisted TKA (raTKA) are limited. This prospective comparative cohort study aimed to compare early postoperative outcomes, satisfaction, and patient-reported outcome measures (PROMS) between patients undergoing mTKA and ROSA raTKA (Zimmer Biomet, Warsaw, IN) performed by one surgeon. METHODS Thirty ROSA raTKAs and 30 mTKAs performed by one surgeon during 2020-2021 were prospectively evaluated. Groups were matched for age, sex, and body mass index. All procedures were primary unilateral TKAs using the same posterior-stabilized prosthesis (Nexgen Legacy, Zimmer Biomet, Warsaw, IN). Length of hospital stay (LOS) and blood transfusion rate were recorded. Complications, visual analogue scale score (VAS), and Oxford Knee Score (OKS) were assessed preoperatively and for six postoperative months. The Forgotten Joint Score (FJS) and patient satisfaction were evaluated 6 months postoperatively. RESULTS No complications and similar blood transfusion rate were recorded between groups (p = 0.228). The LOS was non-significantly shorter in raTKA than in the mTKA group (p = 0.120). Mean preoperative and third-month OKS and VAS scores were comparable between groups. However, the mean 6-month OKS (p = 0.006) and VAS score (p = 0.025) were significantly better for the raTKA group. The 6-month FJS was significantly greater for raTKA than the mTKA group (p < 0.001). One patient was unhappy in raTKA, and three in the mTKA group (p = 0.301). Significantly more raTKA patients answered that they would undergo surgery again (p = 0.038). CONCLUSION raTKA was associated with the same complication risk, less pain level, better patient satisfaction, and PROMs on 6-month follow-up than the mTKA group.

Abstract
BACKGROUND The direct superior hip approach (DSA) has been less researched than other approaches in the literature. We retrospectively compared the early postoperative and functional outcomes of patients with hip osteoarthritis undergoing total hip arthroplasty (THA) via DSA with a matched control group using a standard posterior approach (SPA). METHODS The DSA group comprised 100 THAs performed via DSA by a senior surgeon between January 2018 and May 2019. Patients with primary osteoarthritis and ASA score ⩽3 who were eligible for surgery were included. The DSA group was compared to a matched cohort of 100 patients operated on with a SPA in the same period by another chief surgeon. Patients were matched for age, sex, and ASA score. All patients received the same postoperative chemoprophylaxis, pain management and physiotherapy. 2 independent attending arthroplasty surgeons assessed the incision length, operative time, blood loss, hospital stay, and complications. VAS, HHS, and HOOS scores were also evaluated for a year postoperatively. RESULTS Mean incision length and hospital stay were significantly lower in the DSA group. DSA patients had non-significantly lower intraoperative blood loss, transfusion needs, and postoperative pain than SPA patients. Mean operation time and complication rate did not differ between groups. The DSA group demonstrated significantly greater functional scores than the SPA group at the first postoperative month. No differences in scores were recorded following the third month. CONCLUSIONS The DSA approach may provide earlier functional recovery and hospital discharge for THA patients compared with SPA. DSA was equivalent to SPA concerning pain and blood loss, showing minimal complication rates.

Abstract
Progressive matrix metalloproteinase (MMP)-induced degradation of the extracellular matrix (ECM) of the articular cartilage is one of the major pathogenic osteoarthritis (OA) events. Several single nucleotide polymorphisms (SNPs) in genes encoding MMPs have been identified as affecting MMP expression, production, and enzymatic activity. This study systematically reviews the literature regarding the association between the SNPs of genes encoding MMPs and the risk of knee OA. An electronic search in the PubMed and Web of Science databases from conception to January 2021 was performed addressing studies relating MMPs genetic polymorphisms with the risk of knee OA. We included case-control studies that used validated genotyping methods to detect the SNPs’ association in MMP genes with primary knee OA risk. Ten studies were finally included in this systematic review, evaluating different SNPs in six MMP genes in terms of knee OA pathogenesis: MMP-1 (3 SNPs), MMP-2 (1 SNP), MMP-3 (9 SNPs), MMP-8 (10 SNPs), MMP-9 (6 SNPs), and MMP-13 (1 SNP). Among them, nine SNPs of four MMP genes have been associated with knee OA: (a) MMP-1 -1607 1G/2G (Turkish, Chinese), (b) MMP-3 rs650108, rs650108, rs520540, rs602128, rs679620 (Chinese), (c) MMP-8 rs1940475 and rs376520 (Finnish), and (d) MMP-13 77A/ (rs2252070) (Chinese). The present review summarizes all known SNPs of MMP genes related to a higher risk of knee OA. There are at least nine SNPs in four MMP genes associated with knee OA. No solid correlation between MMP genotype and knee OA phenotype exists. More high-quality studies and modern genetic testing methods are needed to fully elucidate the role of polymorphisms of MMP genes in knee OA pathogenesis.

Abstract
INTRODUCTION Monoblock cups have theoretical advantages over modular cups; however, their superiority in terms of survival has not been confirmed in comparative studies. METHODS We compared the mid-term survivorship of 107 RM Pressfit vitamys monoblock cups (Mathys Ltd., Bettlach, Switzerland) with 93 modular pressfit Pinnacle cups (DePuy Synthes, Warsaw, IN, USA). All cases were registered in the Arthroplasty Registry Thessaloniki and performed by a senior surgeon through the same approach between 2013 and 2014. The groups were comparable in sex distribution, preoperative diagnosis, follow-up, cup diameter, head diameter, type and use of screws, HOOS and HSS preop scores; the recipients of RM cup were significantly younger. RESULTS 3 sockets were revised. The 6-year survival for any reason was 99.1% for the RM and 97.8 % for the PINNACLE group. There was no difference in survival for aseptic loosening and any reason between groups (log-rank test p = 0.921 and p = 0.483, respectively). The age (95% CI, 0.79-1.1), sex (95% CI, 0.2-45.0), cup diameter (95% CI, 0.18-1.1), head diameter (95% CI, 0.004-6.2), preoperative diagnosis and use of screws (95% CI, 0.02-4.3), did not influence hazard ratio for revision between groups. HHS and HOOS were comparable at the last follow-up. CONCLUSIONS Our study demonstrated that both cup designs had similar revision rates at mid-term follow-up, regardless the fact that the RM vitamys was used in a cohort of younger patients; which according to the literature would have led to earlier failures. Further long-term data are needed to evaluate the superiority of RM vitamys in the clinical setting, especially in the young.

Abstract
PURPOSE Anterior femoral notching (AFN) may be associated with a higher risk for supracondylar periprosthetic fracture (sPPF) after total knee arthroplasty (TKA), although studies have yielded inconclusive results. We aimed to systematically investigate and meta-analyze the best available evidence regarding the association between AFN and the risk of sPPF after TKA. METHODS A comprehensive search of PubMed, Scopus, Mendeley, Google Scholar and Cochrane databases was performed, from conception to February 29, 2020. Data were expressed as odds ratio (OR) with 95% confidence intervals (CI). I2-index was employed for heterogeneity. Newcastle-Ottawa scale was implemented for quality assessment of the included studies. RESULTS Nine studies fulfilled the eligibility criteria, including a total of 3264 patients subjected to TKA. Among them, there were 150 patients who sustained a sPPF. Overall, patients exposed to AFN (AFN group) demonstrated an increased risk for sPPF compared to those not exposed (control group) (OR 3.91, 95% CI 1.22-12.58, p = 0.02; I2 68.52%). Subgroup analysis based on AFN depth with a cut-off value of 3 mm further clarified this association. Patients with AFN ≥ 3mm were at higher risk for sPPF compared to patients with AFN < 3 mm and control group (OR 4.85, 95% CI 2.08-11.33, p = 0.00; I2 0.0%). On the contrary, fracture risk was not significant for patients with AFN < 3 mm compared to the control group (OR 5.0, 95% CI 0.44-56.82, p = 0.19; I2 42.99%). CONCLUSION Patients, exposed to AFN ≥ 3 mm in depth, are at higher risk for sustaining a sPPF.

Abstract
PURPOSE The exact effect of vitamin D supplementation, either as monotherapy or in combination with protein, on musculoskeletal health in patients with sarcopenia is currently unknown. This study aimed to determine the effect of vitamin D alone or with protein supplementation on muscle strength, mass, and performance in this population. METHODS A comprehensive search was conducted in Medline, Cochrane Central and Scopus databases, up to March 31st, 2020. Data were expressed as standardized mean difference (SMD) with 95 % confidence intervals (CI). I2 index was employed for heterogeneity. RESULTS The initial search identified 1164 studies, eight of which met the eligibility criteria for qualitative and quantitative analysis, yielding a total of 776 patients. Vitamin D (100-1600 IU/day) plus protein (10-44 g/day) supplementation exhibited a beneficial effect on muscle strength, as demonstrated by an improvement in handgrip strength (SMD 0.38 ± 0.07, 95 % CI 0.18-0.47, p = 0.04; I2 76.2 %) and a decrease in the sit-to-stand time (SMD 0.25 ± 0.09, 95 % CI 0.06-0.43, p = 0.007; I2 0%) compared with placebo. However, the effect on muscle mass, assessed by skeletal muscle index, was marginally non-significant (SMD 0.25 ± 0.13, 95 % CI -0.006-0.51, p = 0.05; I2 0%). No effect on appendicular skeletal muscle mass or muscle performance (assessed by walking speed) was observed with vitamin D plus protein. CONCLUSIONS Vitamin D supplementation, combined with protein, improves muscle strength in patients with sarcopenia, but has no effect on muscle mass or performance.

Abstract
There is limited evidence on the outcomes of Total Hip Arthroplasty (THA) in Slipped Capital Femoral Epiphysis (SCFE) patients. This systematic review aims to evaluate the current literature in terms of survival rate, functional outcomes, complications and types of implants of THA in SCFE patients. Following the established methodology of PRISMA guidelines, PubMed, Cochrane library, ScienceDirect and Ovid MEDLINE were systematically searched from inception to September 2018. The search criteria used were: (“total hip arthroplasty’’ OR ‘’total hip replacement’’ OR “hip arthroplasty’’ OR ‘’hip replacement’’) AND (‘’slipped capital femoral epiphysis’’ OR ‘’slipped upper femoral epiphysis’’ OR ‘’femoral epiphysis’’). Ten studies were finally included in the analysis and were qualitatively appraised using the Newcastle-Ottawa tool. Variables were reported differently between studies. The sample size varied from 12 to 374 THAs. A total of 877 patients undergone 915 THAs. The mean reported follow-up ranged from 4.4 to 15.2 years and the mean patients’ age at the time of THA from 26 to 50 years. Four studies specified the type of implants used, with 62% being uncemented, 24% hybrid (uncemented cup/cemented stem) and 14% cemented. All but three studies reported the mean survival of implants that ranged from 64.9% to 94.8%. A limited number of complications were mentioned. There was a tendency for more favorable functional outcomes in modern studies. Modern THA-studies in SCFE patients showed improvement of survivorship, clinical outcomes and patient satisfaction. Future higher-quality studies are necessary to estimate long-term postoperative outcomes better.

Abstract
Diabetes mellitus (DM) is associated with an increased risk of fractures, mainly due to impaired bone architecture and microvascular complications. Whether DM is also associated with increased risk of sarcopenia is not yet known, with studies yielding inconclusive results. The aim of this study was to systematically review and synthesize the best available evidence regarding the association between DM and sarcopenia risk. A comprehensive search was conducted in PubMed, CENTRAL and Scopus databases. Data are expressed as odds ratio (OR) with 95% confidence intervals (CI). The I2 index was employed for heterogeneity. Only studies which had implemented at least two of the three criteria for sarcopenia diagnosis (low muscle mass, muscle strength and/or muscle performance), as defined by the international studying groups, were included. Fifteen studies fulfilled eligibility criteria, yielding a total of 1832 patients with type 2 DM (T2DM) and 1159 cases of sarcopenia. Patients with T2DM demonstrated a higher risk of sarcopenia compared with euglycemic subjects (OR 1.55, 95% CI 1.25-1.91, p < 0.001; I2 34.6%). This risk remained significant when analysis was restricted to studies matched for age and sex. Sarcopenia risk was independent of disease definition or study design. Notably, T2DM patients presented lower muscle performance and strength compared with euglycemic subjects, whereas no difference in muscle mass was observed between groups. Patients with T2DM have an increased risk of sarcopenia compared with euglycemic subjects.

Abstract
INTRODUCTION Direct Superior Approach (DSA) is a muscle sparing approach for total hip arthroplasty (THA) implemented using special instrumentation. There is a lack of information in the literature concerning DSA with standard instrumentation. MATERIALS AND METHODS 238 patients were recruited for primary THA by a single surgeon from January 2016 until May 2017. 209 patients underwent THA through DSA approach with non-offset acetabular reamers and femoral broaches. We evaluated accuracy of implantation, complications and early functional results. Independent orthopaedic surgeons performed the clinical and radiographic assessments. RESULTS 200 patients were followed for a year. 3 different implants were used. No sciatic nerve palsies, hip dislocations or fractures were recorded. There was one acute deep and superficial wound infection. The mean functional score was significantly improved at all follow-ups (p < 0.001). 97% of stems were inserted into the neutral coronal and 96% in neutral sagittal alignment. All cups fell within a safe zone of inclination and 91% of anteversion. 2 hips demonstrated heterotopic ossification, Brooker class I. Obese patients had no increased risk of complications. CONCLUSIONS DSA with standard instrumentation is safe and efficacious for THA. It offers fast recovery and facilitates correct implantation of different implants, can be useful even for hip dysplasia and obese patients with minimal complication rates.

Abstract
Obesity and osteoporosis have become major global health problems over the last decades as their prevalence is increasing. The interaction between obesity and bone metabolism is complex and not fully understood. Historically, obesity was thought to be protective against osteoporosis;however, several studies have challenged this belief. Even though the majority of the studies suggest that obesity has a favourable effect on bone density, it is unclear what the effect of obesity is on skeletal microarchitecture. Additionally, the effects of obesity on skeletal strength might be site-dependent as obese individuals are at higher risk of certain fractures. Several mechanical, biochemical and hormonal mechanisms have been proposed to explain the association between the adipose tissue and bone. Mechanical loading has positive effects on bone health, but this may not suffice in obesity. Low-grade systemic inflammation is probably harmful to the bone and increased bone marrow adipogenesis may lead to decreased bone mass in obese individuals. Finally, visceral abdominal fat may exert different actions to the bone compared with the subcutaneous fat. Achieving a better understanding of the association between adipose and bone tissue may help to identify new molecular therapeutic targets that will promote osteoblastic activity and/or inhibit adipogenesis and osteoclastic activity.

Abstract
During the last decade, a cascade of evidence has questioned the anti-fracture efficacy of vitamin D supplementation. In general, vitamin D status, reflected by serum 25-hydroxy-vitamin D [25(OH)D] concentrations, seems to predict fracture risk and bone mineral density (BMD). Despite the well-documented detrimental effect of vitamin D deficiency on bones, vitamin D monotherapy does not seem to reduce the risk of fractures. On the other hand, high vitamin D doses, either at monthly (60,000-100,000 IU) or daily intervals (>4000 IU), appear to be harmful with regard to falls, fracture risk and BMD, especially for people without vitamin D deficiency and at low fracture risk. Therefore, a U-shaped effect of vitamin D on the musculoskeletal system may be supported by the current evidence. Vitamin D supplementation could be of value, at daily doses of at least 800 IU, co-supplemented with calcium (1000-1200 mg/day), in elderly populations, especially those with severe vitamin D deficiency [25(OH)D <25-30 nmol/L (<10-12 ng/mL)], although its anti-fracture and anti-fall efficacy is modest. Good compliance and at least 3-5 years of therapy are required.

Abstract
Total hip arthroplasty (THA) in sickle cell disease (SCD) patients can be a challenging procedure. This systematic review evaluated the revision rate, functional outcomes and complications of THA in sicklers. A systematic search was conducted according to the PRISMA guidelines, using four search engines from inception to May 2019. Fifteen studies with 971 THAs were included. There were 437 cemented and 520 uncemented THAs. There were 164 revision THAs (16.8%); 52 uncemented and 105 cemented THAs. Forty-two infections were recorded; 16 infections for cemented and 23 for uncemented THAs. Fifty-seven cups, 26 stems, eight cup/stem with aseptic loosening that were more frequently cemented were reported. The 28 unspecified aseptic loosening cases were more frequently uncemented THAs. All studies demonstrated the functional improvement of patients. There were 109 medical complications (14.3%). Sickle cell crises (SCC) and transfusion reactions were most usually recorded. Forty-six intraoperative complications (4.7%) were reported; 18 femoral fractures, four acetabular and 18 femoral perforations. Seventeen femoral fractures occurred during uncemented THA. THA in SCD is still related to a high risk of complications. The outcomes in properly selected sicklers have been improved. Perioperative adequate hydration, warming, oxygen supply and transfusion protocols are mandated to prevent SCC and transfusion reactions. The surgeon must be prepared to deal with a high rate of intraoperative fractures and have different implant options readily available. No definite conclusion can be made regarding the best fixation mode. Cemented implants demonstrated a higher revision rate and uncemented implants a higher risk for intraoperative complications.

Abstract
Introduction A new emerging role of nitric oxide (NO) in the aetiology of osteoarthritis (OA) has been reported. Inducible NO synthase (iNOS), produced by chondrocytes, is the major source of NO in the osteoarthritic cartilage. The aim of this study is to evaluate the potential association between the -1173C/T (rs9282799), -1026 C/A (rs 2779249) and -954G/C (rs1800482) single nucleotide polymorphisms (SNPs) in the promoter of the iNOS gene (NOS2A) and the incidence of knee OA in Greek population. Methods Ninety-six patients with primary knee OA were included in the study along with 44 controls. Genotypes were identified using polymerase chain reaction (PCR) and DNA sequencing techniques. Allelic and genotypic frequencies were compared between patients and controls. Results None of the -1173C/T, -1026 C/A and -954G/C SNPs were detected in the studied population, either in patients or controls. However, another SNP was identified at the site -1056 at the promoter region, where the initial G allele was substituted by the T allele. Interestingly, the TT genotype was completely absent in controls, but was detected in six patients with a 6.2% observed frequency. The difference between patients and controls was not statistically significant (p-value = 0.18). In male OA patients, the observed frequency of the TT genotype was higher (28.6%) in comparison to the 0% of the male controls (p-value = 0.1). The frequency of the G allele was 0.82 in controls and 0.78 in OA patients (p-value = 0.53). Conclusions The present study demonstrates that the 954G/C, -1026C/A, -1056G/T and -1173C/T SNPs of the NOS2A gene are not a risk factor for primary knee OA in Greek population. Moreover, -954G/C, -1026C/A and -1173C/T are rare, if not completely absent, in the Greek population. Additional research is mandatory in order to investigate the association of these SNPs with OA in different ethnic populations.

Abstract
INTRODUCTION Combined achondroplasia and hereditary multiple exostosis (HME) syndrome is a rare autosomal dominant inherited skeletal dysplasia. We report, for the 1sttime, a complex primary hip arthroplasty in a patient with combined achondroplasia and HME syndrome. We emphasize to the femoral and acetabular surgical concerns and difficulties of the surgical exposure and soft tissue balancing for this complex procedure. CASE REPORT An ambulatory 66-year-old female Caucasian with achondroplasia and HME presented with the left hip pain, progressive walk disability and limited range of hip motion due to severe hip osteoarthritis. Full cemented primary total hip arthroplasty (THA) with an impaction grafting technique was performed; posterior lip augmentation device was implanted to improve stability. At 5 years follow-up, the patient remains ambulatory and pain-free with improved range of hip motion. No signs of aseptic loosening are present. CONCLUSIONS Cemented THA could be an efficient option to reconstruct the complex hip anatomy in patients with skeletal dysplasia.

Abstract
INTRODUCTION Pharmacological options to address the imbalance between bone resorption and accrual in osteoporosis include anti-resorptive and osteoanabolic agents. Unique biologic pathways such as the Wnt/β-catenin pathway have been targeted in the quest for new emerging therapeutic strategies. AREAS COVERED This review provides an overview of existing pharmacotherapy for osteoporosis in women and explore state-of-the-art and emerging therapies to prevent bone loss, with an emphasis on the mechanism of action, indications and side effects. EXPERT OPINION Bisphosphonates appear to be a reliable and cost-effective option, whereas denosumab has introduced a simpler dosing regimen and may achieve a linear increase in bone mineral density (BMD) with no plateau being observed, along with continuous anti-fracture efficacy. Abaloparatide, a parathyroid-hormone-related peptide (PTHrP)-analogue, approved by the FDA in April 2017, constitutes the first new anabolic osteoporosis drug in the US for nearly 15 years and has also proven its anti-fracture efficacy. Romosozumab, a sclerostin inhibitor, which induces bone formation and suppresses bone resorption, has also been developed and shown a significant reduction in fracture incidence; however, concerns have arisen with regard to increased cardiovascular risk.

Abstract
PURPOSE Early menopause (EM, age at menopause < 45 years) and premature ovarian insufficiency (POI, age at menopause < 40 years) are associated with an increased risk of osteoporosis. However, their association with increased fracture risk has not been established, with studies yielding conflicting results. The primary aim of this systematic review and meta-analysis was to synthesize studies evaluating the association between age at menopause and fracture risk. The secondary aim was to evaluate this effect concerning the site of fractures. METHODS A comprehensive search was conducted in PubMed, CENTRAL and Scopus, up to 31 January 2018. Data were expressed as odds ratio (OR) with 95% confidence intervals (CI). The I2 index was employed for quantifying heterogeneity. RESULTS Eighteen studies were included in the qualitative and quantitative analysis (462,393 postmenopausal women, 12,130 fractures). Compared with women with age at menopause > 45 years, women with EM demonstrated higher fracture risk (OR 1.36, 95% CI 1.11-1.66, p < 0.002, I² 81.5%). Women with POI did not display any difference in fracture risk compared either with women with age at menopause > 40 (OR 1.23, 95% CI 0.72-2.09, p = 0.436, I² 62.5%) or >45 years (OR 0.54, 95% CI 0.22-1.29, p = 0.17, I2 0%). No difference was evident when a separate analysis was performed for vertebral, non-vertebral and hip fractures. CONCLUSIONS This is the first meta-analysis showing that EM is associated with increased fracture risk compared with normal age at menopause, without any distinct effect on the site of the fracture.

Abstract
Objective/Design Menopausal transition has been associated with a derangement of glucose metabolism. However, it is not known if early menopause (EM, defined as age at menopause <45 years) or premature ovarian insufficiency (POI, defined as age at menopause <40 years) are associated with increased risk of type 2 diabetes mellitus (T2DM). To systematically investigate and meta-analyze the best evidence regarding the association of age at menopause with the risk of T2DM. Methods A comprehensive search was conducted in PubMed, CENTRAL and Scopus, up to January 31, 2018. Data are expressed as odds ratio (OR) with 95% confidence intervals (CI). The I 2 index was employed for heterogeneity. Results Thirteen studies were included in the qualitative and quantitative analysis (191 762 postmenopausal women, 21 664 cases with T2DM). Both women with EM and POI were at higher risk of T2DM compared with those of age at menopause of 45-55 years (OR: 1.15, 95% CI: 1.04-1.26, P = 0.003; I 2: 61%, P < 0.002 and OR: 1.50, 95% CI: 1.03-2.19, P = 0.033; I 2: 75.2%, P < 0.003), respectively). Similar associations emerged when women with EM and POI were compared with those of age at menopause >45 years (OR: 1.12, 95% CI: 1.01-1.20, P < 0.02; I 2: 78%, P < 0.001 and OR: 1.53, 95% CI: 1.03-2.27, P = 0.035; I 2: 78%, P < 0.001), respectively). Conclusions Both EM and POI are associated with increased risk of T2DM.

Abstract
New anti-osteoporotic agents have been developed, potentially enriching the therapeutic armamentarium. Currently available osteoanabolic therapies are the parathyroid hormone (PTH) and PTH-related peptide (PTHrP) synthetic analogues, teriparatide and abaloparatide. Daily administration at doses of 20 and 80 μg, respectively, in contrast to continuous PTH secretion, leads to increased bone formation and reduces vertebral and non-vertebral fracture risk. Teriparatide is more effective than bisphosphonates (alendronate, risedronate) in increasing bone mineral density (BMD), improving bone architecture and reducing fracture risk. Abaloparatide leads to greater BMD gain, has greater anti-fracture efficacy regarding major osteoporotic fractures (upper arm, wrist, hip or clinical spine) compared with teriparatide (without a difference in morphometric vertebral and non-vertebral fractures), and has a lower risk of hypercalcaemia. Romosozumab, a sclerostin inhibitor, both induces bone formation and suppresses bone resorption. Administered at monthly subcutaneous doses of 210 mg, it reduces vertebral, non-vertebral and hip fracture risk compared with either placebo or alendronate. However, concerns have arisen about increased cardiovascular risk, which has suspended its approval by the FDA. Anabolic therapy should always be followed by administration of an anti-resorptive agent, such as bisphosphonates or denosumab, which preserves and may further increase BMD gain. Denosumab provides the greatest benefit for BMD when administered sequentially after its combination with teriparatide for 24 months and constitutes a reasonable option for patients at high risk of fracture. However, longitudinal data are needed to confirm the efficacy and safety of these therapeutic interventions.

Abstract
BACKGROUND The role of the sternum, if any, in the aetiopathogenesis of adolescent idiopathic scoliosis (AIS) remains unexplored. We evaluated morphological features of the sternum for the first time in individuals with AIS. METHODS Medical records of a tertiary hospital were reviewed from 2010 to 2018 to identify adolescents with thoracic or thoracolumbar AIS. We included scoliotic patients between 14 and 18 years of age on radiologic evaluation without previous treatment for the disease. A complete history and 3D computed tomography (CT) scan were also prerequisites for study inclusion. We compared the shape and position of the sternum between adolescents with AIS and age-matched individuals as control. The control group was recruited with a random selection from patients attending hospital for extraskeletal reasons during the same period. Using CT, we evaluated the part of the sternum found in the right front quadrant of the axial plane at the level of the middle of the manubrium of the sternum and apical vertebra. We also provided an evidence-based theory of the sternum involvement in AIS aetiopathogenesis. RESULTS Twelve scoliotic patients with mean age 16.6 and mean Cobb angle 39.7 degrees were included in the study. No difference was found between groups at the level of the manubrium of the sternum (p =0.486). At the level of the apical vertebra, there was a significant difference of the part of sternum found in the right front quadrant of the axial plane between groups (95 % vs 56 %, p <0.001). CONCLUSIONS These are preliminary data demonstrating for the first-time morphological differences of the sternum, between AIS and age-matched non-scoliotic individuals. The sternum of adolescents with AIS was more inclined than non-scoliotic controls that could raise the hypothesis of sternum involvement in AIS pathogenesis. HIPPOKRATIA 2018, 22(4): 173-177.

Abstract
PURPOSE Both type 1 (T1DM) and type 2 diabetes mellitus (T2DM) have been associated with bone fragility and increased fracture risk. However, little is known regarding the effect of anti-osteoporotic treatment on bone mineral density (BMD) and/or fracture risk in these patients. We aimed to systematically investigate the efficacy of anti-osteoporotic medications in patients with diabetes in comparison with non-diabetic subjects. METHODS MEDLINE and Scopus databases were searched (up to 31st October 2017). RESULTS Nine studies fulfilled the pre-defined inclusion criteria [patients with T2DM (n = 8) or either T1DM or T2DM (n = 1)]. Regarding fracture risk, five studies were identified. Alendronate demonstrated comparable vertebral anti-fracture efficacy in patients with and without diabetes (n = 2), whereas non-vertebral fracture risk was either the same (n = 1) or higher in diabetic patients (n = 1). Raloxifene also demonstrated comparable vertebral anti-fracture efficacy in both groups (n = 2), without any effect on non-vertebral fractures in either group. In one study, diabetic patients exposed to raloxifene demonstrated the same vertebral and non-vertebral fracture risk with non-diabetic patients. Teriparatide (n = 1) demonstrated the same non-vertebral fracture rates in both patients with and without T2DM. Regarding BMD, equal increases in spine BMD were observed with alendronate (n = 4), risedronate (n = 1), and teriparatide (n = 1). With respect to hip BMD, similar increases were observed with teriparatide (n = 1), whereas data regarding alendronate were controversial (n = 3). No eligible study was found for zoledronic acid, ibandronate, strontium ranelate, denosumab, or bazedoxifene. CONCLUSIONS The presence of diabetes does not alter anti-osteoporotic treatment response, regarding BMD increase and vertebral fracture risk reduction.

Abstract
Background: Due to the severity of the primary disease in patients with lung cancer, quality of life (QoL) is often overlooked. Factors that form QoL should be taken in consideration when planning the appropriate treatment and determining therapy targets, because of the increasing frequency of bone metastasis leading to high levels of pain. Purpose of this study is to assess quality of life in patients with lung cancer, before and after treatment combined with zoledronic acid. Methods and materials: QoL was assessed in 80 patients (49 males-31 females), of which 45 developed bone metastasis. Prior and post treatment (with co administration of zoledronic acid) seven reliable scales: Pittsburgh Sleep Quality index (PSQI), Epworth Sleeping Scale (ess), Dyspnea Scale (ds), Fatigue Severity Scale (FSS), Brief Pain Inventory (BPI), Fact-G scale for sleep quality and EQ-5D for general health condition. Results: Statistically positive correlations were verified between PSQI-DS, PSQI-FSS, BPI-ESS, DS-FSS, DS-BPI and BPI-FSS (p<0,005) prior and post treatment. Patients sleep quality was improved, pain levels decreased and betterment in quality of life was marked (p<0,001). Although significant decrease in fatigue levels was observed (p<0,001) there has been an increase in dyspnea symptoms (p<0,001). Conclusions: Significant improvement was apparent when zoledronic acid was co administered in any treatment in patients with lung cancer. Sleep quality, fatigue and pain parameters also improved, with no positive impact on the symptoms of dyspnea.

Abstract
BACKGROUND Tranexamic acid (TXA) is efficiently used to control blood loss during total knee arthroplasty (TKA). The role of intraarticular epinephrine needs further clarification. Limited data exist, concerning the combined use of intravenous and intraarticular TXA plus epinephrine in the intraoperative management of blood loss in patients undergoing TKA. METHODS This study aimed to evaluate the safety and efficacy of intravenous and intraarticular TXA plus epinephrine in the intraoperative blood management in primary TKA. In this case-control study, 204 patients undergoing primary cemented TKA were enrolled. One hundred two patients received one gr TXA intravenously and intraarticular injection of a mixture containing 500 mg TXA and 0.6 mg epinephrine. They compared to a historical control group comprised of 102 patients that received the same drug combination without epinephrine. The two groups were comparable concerning age, sex, the grade of osteoarthritis, and preoperative hemoglobin and hematocrit. RESULTS The epinephrine group had significantly higher postoperative hemoglobin (11.70 vs 10.75, p <0.001) and hematocrit (35.70 vs 32.25, p <0.001) compared to the control group at the first postoperative day. The epinephrine group received fewer transfusions, not reaching statistical significance (p =0.110), compared to the control group during hospitalization. The rate of complications was similar between the groups. The combined use of TXA and epinephrine was positively associated with a smaller postoperative hemoglobin drop. CONCLUSION The combination of intravenous and intraarticular TXA plus epinephrine was safe and reduced the drop of hemoglobin at the first postop day but not significantly the rate of transfusions, in patients undergoing primary TKA. Future higher-level of evidence studies are needed to validate these results. HIPPOKRATIA 2018, 22(2): 86-90.

Abstract
INTRODUCTION Denosumab is a monoclonal antibody that received approval by the FDA for the treatment of osteoporosis in 2010. Available higher level research evidence concerns the treatment of patients that have not received any anti-osteoporotic medication in the past. Further investigation is warranted, since clinicians often face the challenge of administering the most efficacious drug in patients, pretreated with other medications. AREAS COVERED We conducted a systematic review and meta-analysis to evaluate the efficacy and safety of denosumab compared to other active anti-osteoporotic agents in patients formerly receiving other treatments. We searched MEDLINE, EMBASE, CENTRAL, the metaRegister of Controlled Trials (mRCT) and clinicaltrials.gov up to April 2017 to identify eligible trials in patients with primary osteoporosis. EXPERT OPINION Our meta-analysis included 6 Randomised Controlled Trials encompassing 2968 patients formerly treated with anti-osteoporotic medications. Quantitative data synthesis demonstrated superiority of denosumab in augmenting Bone Mineral Density in all skeletal sites studied compared to controls [treatment difference in total hip: 1.59% (95% CI 1.01, 2.17)], whereas the overall incidence of serious adverse events was not increased (OR 1.12, 95% CI 0.85 to 1.47, p = 0.42). Future research geared towards the fracture incidence, quality of life and patient reported outcomes is warranted.

Abstract
INTRODUCTION Inducible nitric oxide synthase (iNOS) is the enzyme responsible for the production of nitric oxide (NO), a major proinflammatory and destructive mediator in osteoarthritis (OA). Areas covered: This is a comprehensive review of the recent literature on the involvement of iNOS in osteoarthritis and its potential to be used as a target for OA treatment. Evidence from in vitro, in vivo and human studies was systematically collected using medical search engines. Preclinical studies have focused on the effect of direct and indirect iNOS inhibitors in both animal and human tissues. Apart from direct inhibitors, common pharmacological agents, herbal and dietary medicines as well as hyperbaric oxygen, low level laser and low intensity pulsed ultrasound have been shown to exhibit a chondroprotective effect by inhibiting the expression of iNOS. Expert opinion: Data support the further investigation of iNOS inhibitors for the treatment of OA in human studies and clinical trials. Indirect iNOS inhibitors such as interleukin 1 inhibitors also need to be studied in greater detail. Finally, human studies need to be conducted on the herbal and dietary medicines and on the non-invasive, non-pharmacological treatments.

Abstract
BACKGROUND Essential Skills in the Management of Surgical Cases (ESMSC) is an international undergraduate surgical masterclass which combines ex vivo, dry lab and high fidelity in vivo simulation-based learning (SBL). It consists of 32 stations of skills-based learning, including open reduction internal fixation (ORIF) of fractures. Current literature suggests early involvement in skills-based learning at the undergraduate level is vital. AIMS To compare students' dexterity and skills-based performance with demographic and educational background parameters. METHODS 112 medical students from European Union countries including the United Kingdom, Germany, Greece, Cyprus, Germany, and Bulgaria were selected from a competitive pool of candidates to attend the course. Students undertook ORIF in an ex vivo swine model, and in a simulated fracture on a bamboo rod. Skills-based performance was assessed by two consultant surgeons with validated direct observation of procedural skills (DOPS) forms. Anxiety was self-assessed using the Westside Anxiety Scale prior to the ORIF stations. Dexterity was measured with the O'Connor tweezer dexterity test. RESULTS Female students had significantly higher dexterity scores (median difference 7, p =.003). Right-handed students achieved higher dexterity than left-handed students (median difference 7, p =.043). There was no difference in students' performance across different medical schools, and across year groups (p <.05 for any correlation). Self-reported anxiety was not correlated with high fidelity skills-based performance (r = 0.032, p =.74). CONCLUSION Anxiety does not seem to play a significant role in Simulation Skills-Based learning. Undergraduate surgical curricula should incorporate SBL-based modules to enhance practical skills learning and motivate future orthopedic surgeons.

Abstract
PURPOSE Anterior cruciate ligament (ACL) injury is associated with a pathologic gait pattern and increased energy cost during locomotion. ACL reconstruction could improve the gait pattern. Hamstrings tendon (HAM) and bone-patellar tendon-bone (BPTB) grafts are usually used for reconstruction. The aim of this study was to compare the efficacy of anatomic ACL reconstruction with HAM and BPTB grafts on improving and normalizing the energy cost and physiologic reserves during flat, uphill, and downhill walking. METHODS Twenty male subjects with unilateral ACL injuries were randomly assigned to ACL reconstruction with a HAM (n = 10) or BPTB (n = 10) graft. Ten matched controls were also enrolled. All participants performed three 8-min walking tasks at 0, +10, and -10 % gradients before and 9 months after surgery. Energy cost (oxygen consumption, VO2), heart rate (HR), and ventilation (VE) were measured. Lysholm/IKDC scores were recorded. RESULTS Pre-operatively, VO2, HR, and VE were higher in the HAM and BPTB groups than in controls during walking at 0, +10, and -10 % gradients (p < 0.001-0.01). Post-operatively, both HAM and BPTB groups showed reduced VO2, HR, and VE during the three walking tasks (p < 0.001-0.01). Although the post-operative VO2 in both surgical groups reached 90-95 % of the normative (control) value during walking, it remained elevated against the value observed in controls (p < 0.001-0.01). The HAM and BPTB groups showed no differences in post-surgical VO2 or HR during walking at all three gradients. CONCLUSION Anatomic ACL reconstruction with either HAM or BPTB graft resulted in similar short-term improvements in energy cost and nearly normalized locomotion economy and cardiorespiratory reserves during flat, uphill, and downhill walking. The improved locomotion economy is an additional benefit of anatomic ACL reconstruction, irrespective of the type of graft used, that the orthopaedic surgeons should consider. LEVEL OF EVIDENCE II.

PURPOSE Patients with ACL injury requiring surgical treatment (non-copers) demonstrate altered neuromuscular control and gait pattern compared with those returning to their pre-injury activities without surgery (copers). Pathological gait pattern may increase the energy cost of walking. We compared the energy cost of flat, uphill, and downhill walking between ACL-deficient and healthy individuals and between "copers" and "non-copers". METHODS Nineteen young males with unilateral ACL injury were allocated into "copers" and "non-copers" according to their ability to return to pre-injury activity without ACL reconstruction. Lysholm and IKDC scales were recorded, and a control group (n = 10) matched for physical characteristics and activity levels was included. All participants performed 8-min walking tasks at 0, +10, and -10 % gradients. Energy cost was assessed by measurement of oxygen consumption (VO2). HR and ventilation (VE), respiratory exchange ratio (RER), and VE/VO2 were also measured. RESULTS VO2 and HR were higher in ACL-deficient patients than in controls during walking at 0, +10, and -10 % gradients (p < 0.01-0.05). There were no differences between "copers" and "non-copers" in VO2 and HR for any gradient. No differences were observed in VE, RER, and VE/VO2 among the three groups. CONCLUSIONS The walking economy of level, uphill, and downhill walking is reduced in ACL-deficient patients. Despite the improved functional and clinical outcome of "copers", their walking economy appears similar to that of "non-copers" but impaired compared with healthy individuals. The higher energy demand and effort during locomotion in "copers" and "non-copers" has clinical implications for designing safer rehabilitation programmes. The increased energy cost in "copers" may be another parameter to consider when deciding on the most appropriate therapeutic intervention (operative and non-operative), particularly for athletes.

Abstract
BACKGROUND Prognostic value of Salter-Harris (SH) classification is well established. Its reliability, however, can be questioned. We aim to evaluate the interobserver and intraobserver reliability of SH classification and to correlate the level of rater's experience with the correct scoring for each SH subclass. METHODS Twenty-eight independent raters stratified in three levels of seniority evaluated 50 randomly selected radiographs of physeal injuries. The interval for intraobserver reliability was 12 weeks. The overall agreement between raters was assessed using kappa statistics. Student's t-test and Spearman correlation coefficient used to compare results between groups. RESULTS Overall kappa for interobserver reliability was 0.45. The mean kappa difference between specialists and residents was significant (p <0.001). The mean kappa difference was also significant between senior and junior residents (p <0.001), favoring senior residents. Intraobserver kappa differs between specialists (0.55) and residents (0.49), but this did not reach statistical significance (p =0.34). SH type II and III demonstrated the highest category-specific kappa coefficient. Seniority was correlated significantly with the number of correct answers (Spearman rho =0.6 p =0.001). CONCLUSIONS Moderate interobserver reliability that was improved with greater rater's experience was found. Type II and III are the best scored regardless rater's experience. Type I, IV, and V when in doubt, require additional imaging. Hippokratia 2016, 20(3): 222-226.

Abstract
OBJECTIVE To evaluate serum Dickkopf-1 (Dkk-1), sclerostin and vascular endothelial growth factor (VEGF) levels in patients with ankylosing spondylitis (AS) compared to healthy controls as well as their association with smoking, and clinical, inflammatory and radiographic parameters. METHODS Serum samples for total Dkk-1, sclerostin and VEGF were obtained from 57 tumour necrosis factor (TNF) inhibitor naïve patients with AS and 34 sex-, age- and body mass index (BMI)-matched controls. The erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI), modified Stroke AS Spine Score (mSASSS) and smoking status were assessed for each patient. RESULTS There was no significant difference in serum bone metabolism markers between AS patients and controls. Dkk-1 levels were significantly (P<0.05) higher in AS patients with elevated ESR and CRP and no syndesmophytes, and were significantly (P<0.001) correlated with sclerostin levels (r=0.592). VEGF levels were significantly (P<0.05) higher in AS patients with current and ever smoking, elevated ESR and CRP, and high BASDAI and BASFI, and were significantly (P<0.05) correlated with ESR (r=0.284), CRP (r=0.285), BASDAI (r=0.349) and BASFI (r=0.275). In multivariate regression analyses, high Dkk-1 levels were significantly (P≤0.001) associated with elevated ESR and CRP, no syndesmophytes and high sclerostin levels, and high VEGF levels significantly (P<0.05) with ever smoking, and elevated ESR and CRP. CONCLUSION In AS, serum Dkk-1 concentrations appear to be related not only to syndesmophyte formation but also to systemic inflammation. Furthermore, high VEGF levels may be associated with smoking exposure.

Abstract
Background Scoliotic curves do not necessarily stop progressing at skeletal maturity. The factors that influence curve behavior following bracing are not fully determined. Our objectives were to evaluate the loss of the scoliotic curve correction in a cohort of patients treated with bracing during adolescence and to compare the outcomes of 18 versus 23 h of bracing at a mean of 25 years post brace removal. Methods Seventy-seven patients, who were successfully treated for Adolescent Idiopathic Scoliosis with Βoston brace, were re-evaluated 25 years after the end of their treatment. Patients were further divided in 2 matched groups; those wearing the brace for 23 h and those not wearing the brace at school-time, limiting the application of the brace to 18 h. The mean scoliotic curve was compared between groups before, during, just after bracing and 25 years post bracing. Validated in patients’ native language forms of Short Form 36 and Oswestry Disability Index questionnaires were used to compare the quality of life between groups 25 years post bracing. Results The mean age of the cohort was 40.4 (±3.2) years. They underwent long term follow up at a mean of 25.16 (±2.69) years after brace removal. The mean cohort scoliotic curve increased by 3.9 (±6.69) at 25 years since brace removal. There was however no significant difference in the mean Cobb angle of the cohort between pre brace and long term follow up period (p = 0.307). The 18 and 23 h application groups were comparable according to demographics and several bracing and scoliotic curve parameters. There was no significant difference in the mean curve magnitude between 18 and 23 h application groups at brace removal (p = 0.512) and at 25 years follow-up (p = 0.878). There was also no significant difference in the mean score of Quality of Life questionnaires between groups at long term follow up. Conclusion Scoliotic curves do not necessarily stop progressing after bracing. Bracing is effective treatment method with good long term results in appropriate patients. Since compliance was not objectively measured, we don’t feel confident to give any indication about everyday dosage.

Abstract
BACKGROUND The Scoliosis Research Society-22r Questionnaire (SRS-22r) is a questionnaire assessing the health related quality of life of patients with scoliosis. Aim of this study was to evaluate the validity and reliability of the Greek Version of the SRS-22r in patients suffering from scoliosis who were treated conservatively. METHODS The (translated and adapted) Greek versions of the SRS-22r together with the previously validated Short Form-36 questionnaire were mailed to 117 patients suffering from idiopathic scoliosis. Two weeks later, the Greek SRS-22r was mailed to the same patients once again. The internal consistency, reproducibility and concurrent validity were assessed. RESULTS Factor analysis revealed a five-factor structure. The study demonstrated high Cronbach α coefficients for all but the 'Satisfaction with management' domain, when compared with the original questionnaire. Intraclass correlation was excellent regarding every domain of the SRS-22r. Concerning concurrent validity, one domain had excellent (r=0.75-1), thirteen domains good (r=0.50-0.75) and 16 domains moderate correlations (r=0.25-0.50) when compared with the relevant domains of the SF-36 questionnaire. CONCLUSIONS This Greek Version of the SRS-22r outcome instrument is a validated questionnaire which can be used to evaluate Greek-speaking patients suffering from Idiopathic Scoliosis who are being treated conservatively.

Abstract
STUDY DESIGN Various neurophysiological parameters of the motor system were investigated in 43 female patients with Idiopathic Scoliosis (IS) and 31 sex and age matched controls using transcranial magnetic stimulation (TMS). OBJECTIVE To investigate whether asymmetries in excitatory and inhibitory brain processes, as studied by TMS, are a causative factor in IS. SUMMARY OF BACKGROUND DATA Previous studies associated IS with pathological asymmetries of the cerebral cortex and the brain stem at the level of the corticospinal tracts. METHODS Forty-three female patients with right IS and 31 normal female subjects entered the study. Various TMS parameters, including the study of ipsilateral pyramidal tract, were studied. Electrophysiological data were correlated with clinical data, the degrees of the scoliotic curve and the Perdriolle and Nash & Moe indexes. RESULTS In upper limbs, detailed testing failed to reveal any statistically significant differences between the patient and the control group. In lower limbs, side-to-side differences of central motor conduction time (CMCT) and facilitated cortical-to-muscle latencies were increased in the scoliotic patients (p<0.05). This finding correlated significantly with Nash & Moe and Perdriolle indexes (Spearman's r=0.406 and 0.575, respectively, p<0.05). Following the Bonferroni adjustment, however, differences in CMCT SSDs were not statistically significant (p>0.05). CONCLUSION The present TMS data do not support the concept of a generalized brain asymmetry in IS. In lower limbs, a trend towards increased asymmetries in side-to-side differences of CMCT and cortical latencies was detected probably representing subclinical involvement of the corticospinal tracts secondary to mechanical compression. Finally, it is concluded that non-decussation of the pyramidal tracts is not involved in the pathogenesis of IS.

Abstract
Trochanteric bursitis is a clinical condition which simulates major hip diseases and low back pain, it may also mimic nerve root pressure syndrome. Patients with greater trochanteric bursitis pain syndrome (GTBPS) usually suffer from pain radiating to the posterolateral aspect of the thigh, paraesthesiae in the legs, and tenderness over the iliotibial tract.. The purpose of this study is to indicate the similarity between the clinical features of the GTBPS and those of chronic low back pain, and to highlight the importance of diagnosing GTBPS in patients complaining of low back conditions. Three hundred female patients were included in this prospective study. All patients complained about chronic low back pain or sciatica and had a failed long term conservative treatment. Local injection of the tender peritrochanteric area was only done in half of the patients (group 1). Patients were required to answer the Oswestry Disability Index Questionnaire during all periods of follow-up. Patients of group 1 had a better clinical outcome (p < 0.0005) than the patients in group 2 where no injection was done. We conclude that greater trochanter bursitis pain syndrome is a frequent syndrome which may be associated with low back symptoms. Patients with a long standing history of low back pain and sciatica should be routinely checked for GTBPS. GTBPS is easy to diagnose and can be treated. Peritrochanteric infiltration with glucocorticoids mixed with 2% lidocaine relieves patients from their symptoms for a long period of time. Recurrence should always be expected, but treatment may be repeated.

Abstract
The cause of idiopathic scoliosis remains unknown, although research has possibly eliminated some hypothetical causes. Recent reports associating scoliosis convexity with equilibrium control central processing and motor lateralization have suggested that idiopathic scoliosis is connected causally with the motor cortex. In order to analyze these factors a study of labyrinthine function was carried out. This study included seventeen female patients 12 to 14 years old (mean age= 13.36y) with right thoracic idiopathic scoliosis and twelve normal control females 12 to 14 years old (mean age =13.1y). An electro-nystagmographic study of labyrinthine function (potential nystagmus) was performed in all the patients of the study with caloric tests. The nystagmus was recorded with the electronystagmographic technique (ENG) using Hartmann device. We evaluate these parameters: Slow phase velocity (SPV), Total amplitude (Tamp), Frequency of nystagmus (Freq). No children of the study presented spontaneous nystagmus. No correlation was found between the convexity of the curvature and the direction of nystagmus in posture tests. There were no significant differences between left- and right- beating nystagmus. The results are discussed with special reference to aetiology in idiopathic scoliosis.
