Abstract
The musculoskeletal system involves multiple tissues which are constantly exposed to being exposed to various biological and mechanical stimuli. As such, isolating and studying a particular system from a complex human clinical environment is not always a realistic expectation. On top of that, recruitment limitations, in addition to the nature of orthopaedic interventions and their associated cost, sometimes preclude consideration of human trials to answer a clinical question. Therefore, in this mini review, we sought to rationalize the rapid evolution of biomedical research at a basic scientific level and explain why the perception of orthopaedic conditions has fundamentally changed over the last decades. In more detail, we highlight that the number of orthopaedic in vitro publications has soared since 1990. Last but not least, we elaborated on the minimum requirements for conducting a scientifically sound infection-related laboratory experiment to offer valuable information to clinical practitioners. We also explained the rationale behind implementing molecular biology techniques, ex vivo experiments, and artificial intelligence in this type of laboratory research.

Kitridis D, Tsikopoulos K, Givissis P, Chalidis B. Percutaneous Fixation for Traumatic Symphysis Pubis Disruption-Are the Results Superior Compared to Open Techniques? A Systematic Review and Meta-Analysis of Clinical and Biomechanical Outcomes. J Clin Med 2023; 12:4988. [PMID: 37568389 PMCID: PMC10420190 DOI: 10.3390/jcm12154988] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Revised: 07/23/2023] [Accepted: 07/25/2023] [Indexed: 08/13/2023] [Imported: 08/29/2023] Open
Abstract
INTRODUCTION Open reduction and reconstruction plate and screws fixation (RPSF) is considered the gold standard for the treatment of traumatic symphysis pubis diastasis (SPD). Percutaneous cannulated screw fixation (PCSF) has recently gained popularity as it may reduce operative time and morbidity. The current systematic review aims to compare the clinical and radiological outcomes of PCSF and RPSF in traumatic SPD and analyze the biomechanical effectiveness of PCSF. MATERIAL AND METHODS The Medline, Scopus, and Cochrane databases were searched until February 2023. The primary outcomes were the incidence of implant failure and revision surgery and the amount of displacement of symphysis pubis. Secondary outcomes were the intraoperative blood loss, the scar length, the operative time, the wound infection, and the patients' functional improvement. RESULTS Six clinical trial studies with a total of 184 patients and nine biomechanical studies were included. There was no significant difference between the two groups regarding the incidence of implant failure, the prevalence of revision surgery, and the amount of postoperative loss of reduction (p > 0.05 for all outcomes). The intraoperative blood loss (14.9 ± 4.2 mL for PCSF versus 162.7 ± 47.6 mL for PCSF, p < 0.001) and the incision length (1.7 ± 0.9 mL for PCSF versus 8 ± 1.4 mL for PCSF, p < 0.001) were significantly lower after PCSF. The mean operative time was 37 ± 19.1 min for PCSF and 68.9 ± 13.6 min for RPSF (p < 0.001). The infection rate was less frequent in the PCSF group (3% for PCSF versus 14.3% for RPSF, p = 0.01). One clinical trial reported better functional recovery after PCSF. In all biomechanical studies, the threshold for implant failure was beyond the applied forces corresponding to daily activities. CONCLUSIONS PCSF for traumatic SPD is associated with less operative time, less blood loss, and a lower infection rate when compared to conventional plate techniques without increasing the incidence of postoperative fixation failure and revision surgery. Moreover, PCSF has been proven to be biomechanically sufficient for stabilization. Therefore, it should be considered an efficient and viable alternative for the reconstruction of SPD when closed reduction can be adequately achieved.

World J Orthop 2022; 13:1015-1028. [PMID: 36439372 PMCID: PMC9685635 DOI: 10.5312/wjo.v13.i11.1015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Revised: 12/01/2021] [Accepted: 10/28/2022] [Indexed: 11/16/2022] [Imported: 08/29/2023] Open
Abstract
BACKGROUND Although the impact of microbial infections on orthopedic clinical outcomes is well recognized, the influence of viral infections on the musculoskeletal system might have been underestimated.
AIM To systematically review the available evidence on risk factors and musculoskeletal manifestations following viral infections and to propose a pertinent classification scheme.
METHODS We searched MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), the Reference Citation Analysis (RCA), and Scopus for completed studies published before January 30, 2021, to evaluate risk factors and bone and joint manifestations of viral infection in animal models and patient registries. Quality assessment was performed using SYRCLE's risk of bias tool for animal studies, Moga score for case series, Wylde score for registry studies, and Newcastle-Ottawa Scale for case-control studies.
RESULTS Six human and four animal studies were eligible for inclusion in the qualitative synthesis. Hepatitis C virus was implicated in several peri- and post-operative complications in patients without cirrhosis after major orthopedic surgery. Herpes virus may affect the integrity of lumbar discs, whereas Ross River and Chikungunya viruses provoke viral arthritis and bone loss.
CONCLUSION Evidence of moderate strength suggested that viruses can cause moderate to severe arthritis and osteitis. Risk factors such as pre-existing rheumatologic disease contributed to higher disease severity and duration of symptoms. Therefore, based on our literature search, the proposed clinical and pathogenetic classification scheme is as follows: (1) Viral infections of bone or joint; (2) Active bone and joint inflammatory diseases secondary to viral infections in other organs or tissues; and (3) Viral infection as a risk factor for post-surgical bacterial infection.

Abstract
Complete talar dislocation—extrusion is an uncommon sequela of high‐energy trauma. When the talus is unavailable for reimplantation, a staged treatment plan with the use (a) of an antibiotic cement spacer, followed by (b) tibiotalocalcaneal fusion with bone allograft interposition, may ensure a good clinical outcome.

Abstract
The anterolateral ligament (ALL) is a primary structure of the anterolateral complex of the knee that contributes to internal rotational stability of the joint. Injury of the ALL is commonly associated with rupture of the anterior cruciate ligament. If left untreated, ALL lesions may lead to residual anterolateral rotational instability of the knee after anterior cruciate ligament reconstruction, which is a common cause of anterior cruciate ligament graft failure. The function of the ALL can be restored by lateral extraarticular tenodesis or anterolateral ligament reconstruction (ALLR). In the lateral extraarticular tenodesis procedure, a strip of the iliotibial band is placed in a non-anatomical position to restrain the internal rotation of the tibia, while in ALLR, a free graft is fixed at the insertion points of the native ALL. Gracilis and semitendinosus grafts have mainly been utilized for ALLR, but other autografts have also been suggested. Furthermore, allografts and synthetic grafts have been applied to minimize donor-site morbidity and maximize the size and strength of the graft. Nevertheless, there has been no strong evidence to fully support one method over another thus far. The present review presents a detailed description of the graft choices for ALLR and the current literature available in regard to the effectiveness and outcomes of published surgical techniques.

Abstract
It is an undeniable fact that systematic reviews play a crucial role in informing clinical practice; however, conventional head-to-head meta-analyses do have limitations. In particular, studies can only be compared in a pair-wise fashion, and conclusions can only be drawn in the light of direct evidence. In contrast, network meta-analyses can not only compare multiple interventions but also utilize indirect evidence which increases their precision. On top of that, they can also rank competing interventions. In this mini-review, we have aimed to elaborate on the principles and techniques governing network meta-analyses to achieve a methodologically sound synthesis, thus enabling safe conclusions to be drawn in clinical practice. We have emphasized the prerequisites of a well-conducted Network Meta-Analysis (NMA), the value of selecting appropriate outcomes according to guidelines for transparent reporting, and the clarity achieved via sophisticated graphical tools. What is more, we have addressed the importance of incorporating the level of evidence into the results and interpreting the findings according to validated appraisal systems (i.e., the Grade of Recommendations, Assessment, Development, and Evaluation system - GRADE). Lastly, we have addressed the possibility of planning future research via NMAs. Thus, we can conclude that NMAs could be of great value to clinical practice.

Abstract
BACKGROUND Iliopsoas muscle abscess (IPA) and spondylodiscitis are two clinical conditions often related to atypical presentation and challenging management. They are both frequently related to underlying conditions, such as immunosuppression, and in many cases they are combined. IPA can be primary due to the hematogenous spread of a microorganism to the muscle or secondary from a direct expansion of an inflammatory process, including spondylodiscitis. Computed tomography-guided percutaneous drainage has been established in the current management of this condition.
AIM To present a retrospective analysis of a series of 8 immunocompromised patients suffering from spondylodiscitis complicated with IPA and treated with percutaneous computed tomography-guided drainage and drain insertion in an outpatient setting.
METHODS Patient demographics, clinical presentation, underlying conditions, isolated microorganisms, antibiotic regimes used, abscess size, days until the withdrawal of the catheter, and final treatment outcomes were recorded and analyzed.
RESULTS All patients presented with night back pain and local stiffness with no fever. The laboratory tests revealed elevated inflammatory markers. Radiological findings of spondylodiscitis with unilateral or bilateral IPA were present in all cases. Staphylococcus aureus was isolated in 3 patients and Mycobacterium tuberculosis in 2 patients. Negative cultures were found in the remaining 3 patients. The treatment protocol included percutaneous computed tomography-guided abscess drainage and drain insertion along with a course of targeted or empiric antibiotic therapy. All procedures were done in an outpatient setting with no need for patient hospitalization.
CONCLUSION The minimally invasive outpatient management of IPA is a safe and effective approach with a high success rate and low morbidity.

Abstract
Adipose tissue and its regenerative products which are isolated with enzymatic or mechanical processing of the harvested fat have been studied in a wide range of degenerative diseases, including osteoarthritis of the knee and hip. Intra-articular injection of these products can provide symptomatic relief of pain and postpone surgery. However, their use in the treatment of thumb carpometacarpal joint (CMCJ) osteoarthritis is limited and just a few studies have been published on that topic. For this reason, a review of the literature was performed by a thorough search of eight terms using the Pubmed database. In total, seven human studies met the selection criteria, including case-control studies, case-series and one case report. In all studies, intra-articular injection of autologous fat in osteoarthritic thumb CMCJ provided reduction in pain and improvement in hand function. Grip and pinch strength showed variable results, from no change to significant improvement. Fat-processing techniques were based on centrifugation and mechanical homogenization but biological characterization of the injected cells was not performed in any study. Although the results are encouraging, a uniformly standardized method of fat processing and the conduction of randomized controlled trials in the future could better evaluate the effectiveness of this procedure for thumb CMCJ osteoarthritis.

World J Orthop 2021; 12:1008-1015. [PMID: 35036343 PMCID: PMC8696598 DOI: 10.5312/wjo.v12.i12.1008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Revised: 08/11/2021] [Accepted: 12/08/2021] [Indexed: 02/06/2023] [Imported: 08/29/2023] Open
Abstract
BACKGROUND Development of infrapatellar saphenous neuroma (ISN) is a well-recognized reason for knee pain following total knee arthroplasty (TKA). So far, very few studies have addressed the development of painful ISN after TKA and its impact on functional outcome and patient satisfaction.
AIM To present the results of surgical treatment for ISN after primary TKA, the level of pain relief, and the improvement of knee motion and function.
METHODS Fifteen patients (13 women, 2 men) with persistent medial pain for more than six months after primary TKA, due to osteoarthritis, underwent surgical excision of ISN. ISN diagnosis was confirmed with the presence of Tinel’s sign along the course of the infrapatellar branch of the saphenous nerve and with pain relief after selective nerve block using local anesthetic. Component loosening, malalignment, instability and infection were excluded systematically in all patients as a source of pain. Pain relief in terms of visual analog scale (VAS), active knee range of motion (ROM), and the Knee Society Score (KSS) for pain and function were evaluated preoperatively and at least six months postoperatively.
RESULTS The mean patients’ age was 71.3 ± 5.4 years old. The mean interval between TKA and neuroma excision was 10 mo (range, 6 to 14 mo), while the mean follow-up was 8 mo (range: 6 to 11 mo). All 15 patients experienced almost complete immediate pain relief and resolution of allodynia and hyperesthesia after surgery. Pain on the VAS scale improved from 8.6 ± 1.3 preoperatively to 0.8 ± 0.9 at the final follow-up (P = 0.001). KSS pain and function scores were improved from 49.3 ± 5.9 and 62.7 ± 12.8 before surgery to 91.8 ± 4.2 and 75.3 ± 11.3 after surgery, respectively (P = 0.001 and P = 0.015). Active knee ROM was also increased postoperatively from 96 ± 4 to 105 ± 6 degrees (P = 0.001). There were no complications and no further operations required.
CONCLUSION ISN should be considered a potential cause of persistent pain following TKA. Neuroma excision not only provides immediate pain relief and resolution of symptoms but may also improve the knee range of motion.

Abstract
BACKGROUND Arthroscopic procedures are commonly performed for rotator cuff pathology. Repair of rotator cuff tears is a commonly performed procedure. The intraoperative evaluation of the tear size and pattern contributes to the choice and completion of the technique and the prognosis of the repair.
AIM To compare the arthroscopic and open measurements with the real dimensions of three different patterns of simulated rotator cuff tears of known size using a plastic shoulder model.
METHODS We created three sizes and patterns of simulated supraspinatus tears on a plastic shoulder model (small and large U-shaped, oval-shaped). Six orthopaedic surgeons with three levels of experience measured the dimensions of the tears arthroscopically, using a 5 mm probe, repeating the procedure three times, and then using a ruler (open technique). Arthroscopic, open and computerized measurements were compared.
RESULTS A constant underestimation of specific dimensions of the tears was found when measured with an arthroscope, compared to both the open and computerized measurements (mean differences up to -7.5 ± 5.8 mm, P < 0.001). No differences were observed between the open and computerized measurements (mean difference -0.4 ± 1.6 mm). The accuracy of arthroscopic and open measurements was 90.5% and 98.5%, respectively. When comparing between levels of experience, senior residents reported smaller tear dimensions when compared both to staff surgeons and fellows.
CONCLUSION This study suggests that arthroscopic measurements of full-thickness rotator cuff tears constantly underestimate the dimensions of the tears. Development of more precise arthroscopic techniques or tools for the evaluation of the size and type of rotator cuff tears are necessary.

Abstract
Background: During notchplasty in anterior cruciate ligament (ACL) reconstruction, bone is excised from the lateral and roof area of the notch to widen the intercondylar space and avoid notch-graft impingement in extension. There are concerns that bone regrowth of the area will cause narrowing and increase the risk of complications. Purpose: To determine the possibility of late narrowing of the notch after notchplasty using computed tomography (CT) analysis. Study Design: Case series; Level of evidence, 4. Methods: Measurements were performed on CT scans (axial and sagittal planes with knee in extension) in patients who had undergone single-bundle anatomic ACL reconstruction using hamstring graft. Two axial image levels were used: at the anterior outlet and the anterior one-eighth level of the notch. The maximum notch height and width, the notch width at one-third and two-thirds of the preoperative notch midwidth height, the maximum condylar width, and the surface area of the lateral half of the notch were measured preoperatively and at 1 week and 2 years postoperatively. Results: Included were 20 consecutive patients (mean ± standard deviation age, 28 ± 7.3 years; follow-up, 24.2 ± 3.3 months). At the anterior notch outlet, the maximum notch width increased by 1.9 ± 1.7 mm at 1 week postoperatively and narrowed by 0.3 ± 1.1 mm at the final follow-up, while the maximum notch height increased by 1.7 ± 1.9 mm and narrowed by 0.8 ± 1.8 mm, respectively. At one-eighth of the roof length, the maximum notch width increased by 1.1 ± 1.7 mm at 1 week postoperatively and narrowed by 0.1 ± 1.1 mm at the final follow-up, and the maximum notch height increased by 1.2 ± 1.5 mm and narrowed by 0.5 ± 1.5 mm, respectively. All differences were statistically significant when comparing the pre- to the immediate postoperative measurements, and they were nonsignificant when comparing the immediate postoperative to the final follow-up measurements. The same applied for the ratio of maximum notch width to maximum condylar width, indicating no postoperative narrowing of the notch. Conclusion: Notch size-shape after a 2-mm notchplasty did not change significantly in stable knees during the first 2 years after anatomic ACL reconstruction. Surgeons should consider performing this adjuvant technique when there is notch-graft impingement during surgery.

Abstract
Background and Objectives: Superior capsular reconstruction (SCR) with the use of a fascia lata autograft or a dermal allograft is an established treatment in treating irreparable rotator cuff (RC) tears. The long head of the biceps tendon (LHBT) has been recently proposed as an alternative graft for SCR. The purpose of this study was to present the surgical techniques and clinical studies utilizing the LHBT for SCR. Material and Methods: Medline, Scopus, and the Cochrane library were searched for relevant studies up to December 2020. The primary outcomes were pain intensity improvement and the incidence of RC and LHBT graft retears. Secondary outcomes were functional scores and acromiohumeral distance (AHD) improvements. Results: Nine studies described surgical techniques of SCR using the LHBT, and four clinical studies reported the outcomes of the technique. The mean pain intensity improved from 4.9 ± 2.3 to 1.6 ± 1.5 in terms of the visual analog scale, exceeding the minimum clinically important difference for adequate pain relief. Significant improvements were also noted in functional scores and AHD. When compared with other repair techniques for massive RC tears, i.e., the double-row repair, the transosseous-equivalent technique with absorbable patch reinforcement, and the traditional SCR with a fascia lata autograft, there were no significant differences in pain and function improvements. Conclusion: SCR using the LHBT is a useful treatment option for massive RC tears; it is equally effective with the traditional SCR and other established techniques. It presents numerous advantages being a safe, easy, time-saving, and cost-effective method. The only precondition for the technique is the presence of an intact LHBT. Additional clinical trials are necessary to determine which treatment is superior for treating massive RC tears, as well as to evaluate the long-term results of the technique.

Abstract
AIM OF THE STUDY To assess the effects of the available coating methods against methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-susceptible S. aureus (MSSA) biofilm development on titanium implants. METHODS We searched the MEDLINE, Embase, and CENTRAL databases until May 18, 2019, for studies that used animal models of infections to evaluate various titanium implant coating methods to prevent S. aureus infection. Twenty-seven studies were eligible for inclusion in qualitative synthesis. Of those, twenty-three were considered in pair-wise meta-analysis. In addition, subgroup analysis of implant protection strategies relative to uncoated controls was performed, and any adverse events stemming from the coating applications were reported. Quality assessment was performed using SYRCLE's risk of bias tool for animal studies. RESULTS Meta-analysis showed that active coating with antibiotics was favoured over uncoated controls (standardised mean differences [SMD] for MRSA and MSSA were - 2.71 [95% CI, - 4.24 to - 1.18], p = 0.0005, and - 2.5 [- 3.79 to - 1.22], p = 0.0001, respectively). Likewise, large effect sizes were demonstrated when a combination of active and conventional non-degradable passive coatings was compared with controls (SMDs for MRSA and MSSA were - 0.62 [95% CI, - 1.15 to - 0.08], p = 0.02, and - 1.93 [95% CI, - 2.87 to - 0.98], p < 0.001, respectively). DISCUSSION/CONCLUSION As a standalone prevention method, active titanium coating with antibiotics yielded promising results against both MSSA and MRSA. Combinations between active and non-degradable passive coatings, potentially allowing for sustained antimicrobial substance release, provided consistent hardware infection protection. Thus, we recommend that future research efforts focus on combined coating modalities against S. aureus biofilm infections in the presence of titanium implants.

Chalidis B, Kitridis D, Givissis P. Tibial tubercle osteotomy in revision total knee arthroplasty: A systematic review. World J Orthop 2020; 11:294-303. [PMID: 32572366 PMCID: PMC7298452 DOI: 10.5312/wjo.v11.i6.294] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2020] [Revised: 05/08/2020] [Accepted: 05/20/2020] [Indexed: 02/06/2023] [Imported: 08/29/2023] Open
Abstract
BACKGROUND Tibial tubercle osteotomy (TTO) is a well-established surgical technique to deal with a stiff knee in revision total knee arthroplasty (RTKA). However, several reports have described potential osteotomy-related complications such as non-union, tibial tubercle migration and fragmentation, and metalware related pain.
AIM To evaluate the literature and estimate the efficiency of TTO in RTKA in terms of osteotomy union, knee mobility and complications.
METHODS MEDLINE, Scopus, and the Cochrane Central Register of Controlled Trials were investigated for completed studies until February 2020. The principle outcome of the study was the incidence of union of the osteotomy. Secondary outcomes were the knee range of motion as well as the TTO-related and overall procedure complication rate.
RESULTS Fifteen clinical studies with a total of 593 TTOs were included. The TTO union rate was 98.1%. Proximal migration and anterior knee pain were the most common TTO-related complications accounting for 6.9% and 6.4% of all cases, respectively. However, only 2.2% of cases suffering from anterior knee pain needed hardware removal. Knee flexion was improved from 82.9° preoperatively to 100.1° postoperatively and total knee range of motion was increased from 73.4° before surgery to 97° after surgery. Stiffness requiring manipulation under anesthesia was recorded in 4.6% of cases. No major complications were reported.
CONCLUSION The current systematic review supports the use of TTO in RTKA, as it is associated with high union rate, significant improvement in knee motion and low osteotomy-related complication risk that rarely leads to secondary tibial tubercle procedures.

Clin Orthop Relat Res 2020; 478:359-377. [PMID: 31625960 PMCID: PMC7438122 DOI: 10.1097/corr.0000000000000946] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2019] [Accepted: 08/08/2019] [Indexed: 01/31/2023] [Imported: 08/29/2023]
Abstract
BACKGROUND To improve ankle stability in patients who have experienced an ankle sprain with residual symptoms of instability and/or objective joint laxity, external supports (such as taping, bracing, and orthotic insoles) are used sometimes. However, available randomized trials have disagreed on whether restraints improve balance in those individuals. In this situation, a network meta-analysis can help because it allows for comparing multiple treatments simultaneously, taking advantage not only of direct but also indirect evidence synthesis. QUESTIONS/PURPOSES The aim of this network meta-analysis was to assess (1) the impact of taping and orthotic devices on dynamic postural control in individuals with ankle instability and (2) the presence of a placebo effect in participants treated with sham taping and complications resulting from the administered treatments. METHODS We searched the PubMed, Scopus, and CENTRAL databases up to February 13, 2019 for completed studies. Randomized trials assessing the results of real and/or sham taping, wait-and-see protocols, ankle bracing, and foot orthotics for ankle instability as determined by one or more ankle sprains followed by ongoing subjective symptoms and/or mechanical laxity were included. We evaluated dynamic postural control in terms of the Star Excursion Balance Test in the posteromedial direction (SEBT-PM), which is considered the most representative of balance deficits in patients with ankle instability. Standardized mean differences were re-expressed to percentage differences in SEBT-PM, with higher scores representing possible improvement. Subsequently, those data were checked against the established minimal detectable change of 14% for this scale to make judgements on clinical importance. We also assessed the presence of a placebo effect by comparing the results of sham taping with no treatment and complications resulting from the administered treatments. Additionally, we judged the quality of trials using the Cochrane risk of bias tool and quality of evidence using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach. A total of 22 trials met our inclusion criteria, 18 of which were deemed to be at a low risk of bias. A network of treatments consisting of 13 studies was created, and the level of evidence was judged to be high. As far as participants' allocation to treatment arms, 85 patients followed a wait-and-see protocol, 29 received placebo taping, 99 were treated with taping, 16 were treated with bracing, 27 were administered insoles, and six individuals were offered a combination of insoles with bracing. Of note, with statistical power set at 80%, a minimum of 16 patients per treatment group was required to provide sufficient statistical power and detect a SEBT-PM percentage difference of 14%. RESULTS A network meta-analysis did not demonstrate a benefit of taping or bracing over no treatment (percentage difference in SEBT-PM between taping and bracing versus control: -2.4 [95% CI -6 to 1.1]; p = 0.18, and -7.5 [95% CI -15.9 to 1]; p = 0.08, respectively). This was also the case for sham taping because the measurement increase failed to exceed the minimal detectable change (percentage difference in SEBT-PM between sham taping and untreated control: -1.1 [95% CI -6.9 to 4.7]; p = 0.72). Importantly, there were no reported adverse events after treatment application. CONCLUSIONS Evidence of moderate strength indicated that external supports of any type were no more effective than controls in improving dynamic postural control in patients with at least one ankle sprain and residual functional or mechanical deficits. Therefore, implementing those tools as a standalone treatment does not appear to be a viable strategy for the primary management of ankle instability. It is conceivable that combinations of rehabilitation and external supports could be more effective than external supports alone, and future trials should evaluate the potential of such combinations in enhancing not only clinician-reported but also patient-oriented outcomes using long-term follow-up measurements. LEVEL OF EVIDENCE Level I, therapeutic study.

Postoperative Administration of Alpha-tocopherol Enhances Osseointegration of Stainless Steel Implants: An In Vivo Rat Model. Clin Orthop Relat Res 2020; 478:406-419. [PMID: 31714415 PMCID: PMC7438137 DOI: 10.1097/corr.0000000000001037] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/31/2023] [Imported: 08/29/2023]
Abstract
BACKGROUND Alpha-tocopherol, a well-known antioxidative agent, may have a positive effect on bone formation during the remodeling phase of secondary fracture healing. Fracture healing and osseointegration of implants share common biological pathways; hence, alpha-tocopherol may enhance implant osseointegration. QUESTIONS/PURPOSES This experimental study in rats assessed the ability of alpha-tocopherol to enhance osseointegration of orthopaedic implants as determined by (1) pull-out strength and removal torque and (2) a histomorphological assessment of bone formation. In addition, we asked, (3) is there a correlation between the administration of alpha-tocopherol and a reduction in postoperative oxidative stress (as determined by malondialdehyde, protein carbonyls, reduced and oxidized glutathione and their ratio, catalase activity and total antioxidant capacity) that develops after implantation of an orthopaedic implant? METHODS This blinded study was performed in study and control groups, each consisting of 15 young adult male Wistar rats. On Day 0, a custom-designed stainless-steel screw was implanted in the proximal metaphysis of both tibias of all rats. On Day 1, animals were randomized to receive either alpha-tocopherol (40 mg/kg once per day intraperitoneally) or saline (controls). Animals were treated according to identical perioperative and postoperative protocols and were euthanized on Day 29. All animals completed the study and all tibias were suitable for evaluation. Implant pullout strength was assessed in the right tibias, and removal torque and histomorphometric evaluations (that is, volume of newly formed bone surrounding the implant in mm, percentage of newly formed bone, percentage of bone marrow surrounding the implant per optical field, thickness of newly formed bone in μm, percentage of mineralized bone in newly formed bone, volume of mature newly formed bone surrounding the implant in mm and percentage of mineralized newly formed bone per tissue area) were performed in the left tibias. The plasma levels of alpha-tocopherol, malondialdehyde, protein carbonyls, glutathione, glutathione disulfide, catalase, and the total antioxidant capacity were evaluated, and the ratio of glutathione to oxidized glutathione was calculated. RESULTS All parameters were different between the alpha-tocopherol-treated and control rats, favoring those in the alpha-tocopherol group. The pullout strength for the alpha-tocopherol group (mean ± SD) was 124.9 ± 20.7 newtons (N) versus 88.1 ± 12.7 N in the control group (mean difference -36.7 [95% CI -49.6 to -23.9]; p < 0.001). The torque median value was 7 (range 5.4 to 8.3) versus 5.2 (range 3.6 to 6 ) N/cm (p < 0.001). The newly formed bone volume was 29.8 ± 5.7 X 10 versus 25.2 ± 7.8 X 10 mm (mean difference -4.6 [95% CI -8.3 to -0.8]; p = 0.018), the percentage of mineralized bone in newly formed bone was 74.6% ± 8.7% versus 62.1% ± 9.8% (mean difference -12.5 [95% CI -20.2 to -4.8]; p = 0.003), the percentage of mineralized newly formed bone per tissue area was 40.3 ± 8.6% versus 34.8 ± 9% (mean difference -5.5 [95% CI -10.4 to -0.6]; p = 0.028), the glutathione level was 2 ± 0.4 versus 1.3 ± 0.3 μmol/g of hemoglobin (mean difference -0.6 [95% CI -0.9 to -0.4]; p < 0.001), the median glutathione/oxidized glutathione ratio was 438.8 (range 298 to 553) versus 340.1 (range 212 to 454; p = 0.002), the catalase activity was 155.6 ± 44.6 versus 87.3 ± 25.2 U/mg Hb (mean difference -68.3 [95% CI -95.4 to -41.2]; p < 0.001), the malondialdehyde level was 0.07 ± 0.02 versus 0.14 ± 0.03 μmol/g protein (mean difference 0.07 [95% CI 0.05 to 0.09]; p < 0.001), the protein carbonyl level was 0.16 ± 0.04 versus 0.27 ± 0.08 nmol/mg of protein (mean difference -0.1 [95% CI 0.05 to 0.15]; p = 0.002), the alpha-tocopherol level was 3.9 ± 4.1 versus 0.9 ± 0.2 mg/dL (mean difference -3 [95% CI -5.2 to -0.7]; p = 0.011), and the total antioxidant capacity was 15.9 ± 3.2 versus 13.7 ± 1.7 nmol 2,2-diphenyl-1-picrylhydrazyl radical/g of protein (mean difference -2.1 [95% CI -4.1 to -0.18]; p = 0.008). CONCLUSIONS These results using an in vivo rat model support that postoperatively administered alpha-tocopherol can enhance the osseointegration of an orthopaedic implant, although a cause and effect relationship between the administration of alpha-tocopherol and a reduction in postoperative stress cannot be securely established. CLINICAL RELEVANCE These findings suggest that postoperative administration of alpha-tocopherol is a promising approach to enhance osseointegration of orthopaedic implants in patients. Further studies with different animal models and/or different implants and those evaluating the alpha-tocopherol dose response are needed before performing clinical trials that will examine whether these promising, preliminary results can be extrapolated to the clinical setting as well.

Abstract
BACKGROUND Several pharmacological interventions are used for the management of adhesive capsulitis of the shoulder, although the optimal treatment has yet to be defined. PURPOSE To conduct a network meta-analysis to compare the effects of different pharmacological interventions for adhesive capsulitis, administered either alone or after distension of the shoulder capsule. STUDY DESIGN Network meta-analysis. METHODS The authors searched Scopus, PubMed, and the Cochrane Central Register of Controlled Trials up to April 22, 2018, for completed studies. They enrolled trials that assessed the results of different pharmacological treatments for the primary management of adhesive capsulitis. The primary outcome was pain relief as measured by self-administered questionnaires. The secondary outcome included the assessment of composite instruments that evaluated, at a minimum, pain and function. The authors clinically interpreted the results after back-transforming the standardized mean differences into mean differences in simple instruments and assessed the quality of the source studies using the Cochrane "risk of bias" tool. RESULTS The authors considered 30 trials with a total of 2010 participants in this systematic review. For pain relief, there was a significant difference in favor of intra-articular corticosteroids and distension of the shoulder capsule with steroids as compared with control in the short term (mean difference in visual analog scale (VAS): -1.4 [95% CI, -2.5 to -0.4] and -1.7 [95% CI, -3.2 to -0.1], respectively). Furthermore, rotator-interval injections were found to be superior to placebo (mean difference in VAS: -7.2; 95% CI, -10.1 to -4.4), although the intervention was considered in only 1 trial. Finally, there was a statistically significant difference in favor of multiple-site corticosteroid injections compared to placebo in both the short- (mean difference in Shoulder Pain and Disability Index [SPADI]: -86.7; 95% CI, -133.6 to -40) and intermediate-term assessment (mean difference in SPADI: -102.9; 95% CI, -163.9 to -41.8). CONCLUSION Intra-articular corticosteroid intervention, administered either alone or after distension of the shoulder capsule, provided clinically meaningful improvements in the short term. Likewise, rotator-interval corticosteroid injections yielded promising results in terms of pain relief. However, these short-term benefits of steroids dissipated over time. Multiple-site corticosteroid injections showed clinical advantage over placebo for short- and intermediate-term composite outcome assessments.

Abstract
BACKGROUND Dorsiflexion closing wedge metatarsal osteotomy (DCWMO) has been considered the traditional treatment of Freiberg disease. Several case reports presented osteochondral autologous transplantation (OAT) as an alternative treatment. PURPOSE/HYPOTHESIS The purpose was to compare the results of DCWMO versus OAT for the treatment of Freiberg infraction in an athletic population. It was hypothesized that OAT was superior to DCWMO regarding functional outcomes, pain, and the time that the athletes returned to training and to previous sport level. STUDY DESIGN Randomized controlled trial; Level of evidence, 2. METHODS Between 2008 and 2013, 27 consecutive patients with Freiberg disease were randomly assigned to either the DCWMO group (14 patients) or the OAT group (13 patients). The primary outcomes collected were as follows: postoperative complications, range of motion of the metatarsophalangeal joint, length of the metatarsal, function of the foot (measured with the American Orthopaedic Foot and Ankle Society-lesser metatarsophalangeal-interphalangeal [AOFAS-LMI] score), and pain (assessed with the visual analog scale-foot and ankle score). RESULTS Mean follow-up was 46 months (range, 36-60 months). The mean ± SD AOFAS-LMI score in the DCWMO group was 63.4 ± 14.4 preoperatively, 81.8 ± 6.6 at 1 year postoperatively, and 84.4 ± 5.6 at 3 years postoperatively, while in the OAT group, it was 62.8 ± 14, 89.9 ± 7.1, and 92 ± 6.9, respectively (P < .001). The differences in the AOFAS-LMI scores favoring the OAT group at 1 and 3 years reached statistical but not clinical significance. The mean visual analog scale-foot and ankle score was improved significantly from 48.1 ± 11.5 to 91.8 ± 9.5 in the DCWMO group and from 49.9 ± 10.9 to 95.4 ± 4.4 in the OAT group. There was a shortening of the metatarsals by a mean 1.9 ± 0.5 mm in the DCWMO group, as opposed to a metatarsal lengthening of 0.2 ± 0.1 mm in the OAT group. In the OAT group, patients were able to start training at 6 ± 1 weeks (P < .001) and return to full sport action at 10 ± 2.5 weeks (P < .05), while in the DCWMO group, the time was 8 ± 1.5 and 13 ± 2.5 weeks, respectively. CONCLUSION The authors concluded that OAT is equal to DCWMO. Acceptable clinical results were reported, as well as very low morbidity and early return to sport activities. That makes the OAT procedure a safe, effective, and optimal treatment for an athletic population experiencing Freiberg infraction.

Abstract
INTRODUCTION Lauge-Hansen classification for ankle fractures is helpful in directing the management of the fracture and has got prognostic significance. However, trimalleolar fractures with double medial malleolar fracture are not yet described. CASE REPORT Two cases of trimalleolar fracture-dislocation of the ankle with a double fracture of the medial malleolus are reported. Both of them had a Weber B fracture of the lateral malleolus, accompanied by a posterior dislocation of the ankle and a fracture of the posterior malleolus. The medial malleolus though presented an interesting variation, a large vertical or oblique fragment was combined with a small horizontal fragment of its tip. CONCLUSION We propose a separate subtype in the Lauge-Hansen classification of supination with combined external rotation and adduction when this pattern of the medial malleolus is accounted. Awareness of this fracture pattern will help better pre-operative planning.

Abstract
BACKGROUND Urinary catheters are commonly used in patients undergoing total hip and knee arthroplasty. Bladder training before catheter removal is reported to shorten the time to return to normal bladder function and reduce the incidence of urinary retention. OBJECTIVE To evaluate the results of bladder training in patients with total hip and knee arthroplasty. DESIGN Randomized controlled trial. SETTING Orthopaedic Department of a tertiary Military Hospital. PARTICIPANTS We enrolled consecutive patients undergoing total hip or knee arthroplasty during a period of 14 months. METHODS We randomly allocated the participants into either a bladder training group, in which clamping was considered prior to catheter removal, or a free drainage removal group, using a computer-generated list and subsequently assessed their need for re-catheterization due to urinary retention. The primary outcome of this study was to evaluate if bladder training in patients with total hip and knee arthroplasty reduces the need for re-catheterization due to urinary retention. Multivariable logistic regression was used to model the association between postoperative urinary retention and independent variables (total hip or total knee arthroplasty, age, gender, and history of diabetes mellitus or prostatism). Secondary outcomes were the incidence of urinary tract infection, and subjective patients' symptoms. RESULTS We included 218 patients in the study; 114 in the bladder training group and 104 in the free drainage removal group. All patients were over 50 years old with a mean age of 69.3 (SD = 8) years. We observed three cases of urinary retention in the bladder training and six in free drainage removal group, and the difference was not statistically significant (2.6% and 5.8% respectively, p = 0.316). We also observed increased odds of re-catheterization in patients with prostatism under medication (odds ratio was 26.42, p < 0.001). No infections or major subjective symptoms were noted. CONCLUSION This trial shows that bladder training by catheter clamping offers no advantage over free draining removal of short-term urinary catheters in patients with total hip and knee arthroplasty. Therefore, we conclude that the bladder training procedure is not indicated. However, healthcare providers should monitor patients' urination after removal of the catheter.

Abstract
BACKGROUND Dorsal closing wedge calcaneal osteotomy is a technique for the treatment of Haglund's triad, which is considered a safe procedure with good results. However, one of the complications that could lead to revision operation is the nonunion of the osteotomy and failure of osteosynthesis. This is attributed to instability of the osteotomy site and proximal migration of the posterior calcaneal process due to breakage of plantar bone-bridge at the apex of the wedge osteotomy. METHODS This study presents a technical tip that helps the surgeon to avoid the breakage of the plantar hinge of the os calcis which is believed that causes instability of the osteotomy. RESULTS After the utilization of that technical tip, no proximal migration of posterior calcaneal process or subsequent nonunion and failure of the osteosynthesis was noted. CONCLUSION Dorsal closing wedge osteotomy is a technique for the treatment of IAT, which is considered a safe procedure with good results. The proposed technical tip helps to avoid the breakage of the plantar hinge which is believed that causes instability of the osteotomy with proximal migration of the posterior calcaneal process and subsequent nonunion and failure of the osteosynthesis.
