Modified Coleman Methodology Score Research Articles

The influence of sex is a neglected focus in rotator cuff repair: A systematic review and meta-analysis.

Rotator cuff (RC) disorders are the most common cause of shoulder disability. The aim of this study was to quantify the evidence on the sex-related differences in RC repair. A systematic review of the literature was performed in January 2023 in PubMed, Wiley Cochrane Library and Web of Science on research articles on humans with RC tears treated surgically. A meta-analysis was performed to compare results in men and women. The Downs and Black score and the modified Coleman methodology score (MCMS) were used to assess the retrieved studies. A total of 39,909 patients were enroled in the 401 studies analysed (45% women, 55% men). A trend toward more sex-balanced recruitment was observed over time. Only 4% of the studies on 1.5% of the documented patients presented disaggregated outcome data and were quantitatively analysed. A tendency for lower range of motion values after surgery was found for external shoulder rotation in women, with 39.9° ± 6.9° versus 45.3° ± 4.1° in men (p = 0.066). According to Downs and Black scores, four studies were good and 12 fair, with a main MCMS score of 69/100. There is a lack of awareness on the importance to document women- and men-specific data. Only 4% of the articles disaggregated data, and it was possible to analyse only 1.5% of the literature population, a sample which cannot be considered representative of all patients. The lack of disaggregated data is alarming and calls for action to better study men and women differences to optimise the management of RC tears. This will be necessary to provide sex-specific information that could be of clinical relevance when managing RC repair. Level IV.

Knee Cartilage Injuries in Football Players: Clinical Outcomes and Return to Sport After Surgical Treatment: A Systematic Review of the Literature.

To systematically review the literature and analyze clinical outcomes and return-to-sport after surgical management of cartilage injuries in football players. A systematic literature review was performed in August 2023 on PubMed, WebOfScience, and Cochrane Library to collect studies on surgical strategies for cartilage lesions in football players. Methodological quality and risk of bias were assessed with the modified Coleman Methodology score and RoB2 and RoBANS2 tools. Fifteen studies on 409 football players (86% men, 14% women) were included: nine prospective and two retrospective case series, one randomized controlled trial, one prospective comparative study, one case report, and one survey. Bone marrow stimulation (BMS) techniques were the most documented. The lesion size influenced the treatment choice: debridement was used for small lesions (1.1 cm2), BMS, osteochondral autograft transplantation (OAT), matrix-assisted autologous chondrocytes transplantation (MACT), and scaffold-augmented BMS for small/mid-size lesions (2.2-3.0 cm2), and autologous chondrocytes implantation (ACI) for larger lesions (5.8 cm2). The surgical options yielded different results in terms of clinical outcome and return-to-sport, with fastest recovery for debridement and scaffold-augmented BMS. The current evidence is limited with large methodological quality variation (modified Coleman Methodology score 43.5/100) and a high risk of bias. Decision-making in cartilage injuries seems to privilege early return-to-sport, making debridement and microfractures the most used techniques. The lesion size influences the treatment choice. However, the current evidence is limited. Further studies are needed to confirm these findings and establish a case-based approach to treat cartilage injuries in football players based on the specific patient and lesion characteristics and the treatments' potential in terms of both return-to-sport and long-term results. Systematic review, level IV.

Evidence-Based Update on the Surgical Technique and Clinical Outcomes of Retrograde Drilling: A Systematic Review.

Retrograde drilling is an established surgical technique to treat osteochondral lesions of the talus (OLT). It involves non-trans-articular drilling to induce subchondral bone revascularization and bone formation without damaging the overlying articular cartilage. The present study aimed to elucidate the heterogeneity of clinical studies on retrograde drilling for OLT. A systematic search of the MEDLINE, Web of Science, EMBASE, and Cochrane Library databases for studies published between January 1996 and August 27, 2022, was performed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines by two independent reviewers. The included studies were evaluated for their level of evidence (LoE) and quality of evidence (QoE) using the Modified Coleman Methodology Score. Variables reporting surgical and clinical outcomes and complications were evaluated. Eleven studies with 207 ankles were included (mean follow-up period = 31.1 months). The mean LoE was 3.8 (LoE 3: two studies, LoE 4: nine studies), and the mean QoE was 50.8 (fair: three studies, poor: eight studies). Ten studies used the American Orthopedic Foot and Ankle Society (AOFAS) score, which improved from 57.9 preoperatively to 86.1 postoperatively. The period and protocol of conservative treatment, lesion character, surgical technique, and postoperative protocol were inconsistent or underreported. This systematic review revealed that low LoE and poor QoE, coupled with heterogeneity among the included studies, impede definitive conclusions regarding the effectiveness of this technique. Consequently, well-designed clinical trials are essential to develop standardized clinical guidelines for using retrograde drilling in OLT.

Medial Collateral Ligament Reconstruction With Autograft Versus Allograft: A Systematic Review.

Medial collateral ligament (MCL) reconstruction (MCLR) is performed after failed nonoperative treatment or high-grade MCL injury with associated valgus instability. To evaluate clinical outcomes after MCLR with autograft versus allograft. Systematic review, Level of evidence, 4. A systematic review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The authors conducted a search of the PubMed, CINAHL, EMBASE, and Cochrane databases to identify studies comparing outcomes of MCLR with autograft versus allograft. Studies were included if they evaluated clinical outcomes after MCLR using autograft and/or allograft. Any study that included concomitant knee ligament injury other than the anterior cruciate ligament injury was excluded. A quality assessment was performed using the modified Coleman Methodology Score. The initial search identified 746 studies, 17 of which met the inclusion criteria and were included in this review. The studies included 307 patients: 151 (49.2%) patients received autografts, and 156 (50.8%) received allografts. The most used autograft was the semitendinosus tendon (136 grafts; 90.1% of specified allografts), and the only allograft used was the Achilles tendon (110 grafts; 100% of specified autografts). The mean follow-up of the studies was 25.6 months. Postoperative pain (Lysholm scores) ranged from 82.9 to 94.8 in patients receiving autografts and 87.5 to 93 in patients receiving allografts. Postoperative range of motion was full in 8 of 15 (53.3%) patients receiving autografts compared with 82 of 93 (88.2%) patients receiving allografts. Five of the 151 (3.3%) patients who had MCLR with autografts had complications such as infection, instability, and prominent screws. Two of the 156 (1.3%) MCLRs with allografts developed complications of prominent screws and nonhealing incisions. MCLR with either autografts or allografts leads to improved patient-reported, radiographic, and clinical outcomes. Patient-reported postoperative pain was similar in patients receiving either graft type. Other outcomes were difficult to compare between graft types because of nonstandardized reporting and a lack of pre- and postoperative measurements. Therefore, there is no evidence of significantly improved outcomes in the use of either autograft or allograft with MCLR.

Non-unions and wound infections do not differ following intramedullary nailing and plate osteosynthesis for distal third femur fractures: a meta-analysis.

The fixation method of distal, extra-articular femur fractures is a controversially discussed. To ensure better stability itself, earlier mobilization and to prevent blood loss - all these are justifications for addressing the femur via reamed intramedullary nailing (RIMN). Anatomical reposition of multifragmentary fractures followed by increased risks of non-union are compelling reasons against it. The purpose of this study was to systematically review the literature for rates of non-union and wound infection, as well as blood loss and time of surgery. According to the PRISMA guidelines we conducted this systematic review by searching the Cochrane, PubMed, Ovid, MedLine, and Embase databases. Inclusion criteria were the modified Coleman methodology score (mCMS) >60, age >18 years, and extra-articular fractures of the distal femur. Biomechanical and animal studies were excluded. By referring to title and abstract relevant articles were reviewed independently. In the consecutive meta-analysis, we compared 9 studies and 639 patients. There is no statistically significant difference comparing superficial wound infections when RIMN was performed (OR = 0.50; 95% CI: 0.18 - 1.42; P = 0.19) as well as in deep wound infections (OR = 0.74; 95% CI: 0.19-2.81; P = 0.62). However, these results were not significant. We also calculated for potential differences in the rate of non-unions depending on the surgical treatment applied. Data of 556 patients revealed an overall number of 43 non-unions. There was no significant difference in rate of non-unions between both groups (OR = 0.97; 95% CI: 0.51-1.85; P = 0.92). No statistical difference was found in our study among RIMN and plate fixation in the treatment of distal femoral fractures with regard to the incidence of non-union and wound infections. Therefore, the indication for RIMN or plating should be made individually and based on the surgeon's experience.

Top fifty cited articles on humeral fractures

Humeral fractures (HF) are common orthopedic pathologies. Reviewing the content and quality of influential literature over time is important to advance scientific research regarding a specific topic. This study aims to explore and appraise the fifty most cited HF studies that had been published in orthopedic literature. The Web of Science database was used to conduct a systematic search for articles pertaining to HF. Articles were sorted out in descending order of citations and were included based on their relevance to HF. Data and metrics of the included studies were recorded. The methodological quality of the studies was assessed using the Modified Coleman Methodology Score (MCMS) and the Methodological Index for Non-randomized Studies criteria. Statistical analysis was conducted to explore any significant relationships between the date of publication and other relevant variables. Included articles (N= 50) were published between 1959 and 2015, with a total of 14,864 accumulated citations. Europe and North America contributed to all but one of the included studies. The Journal of Bone and Joint Surgery contributed to the highest number of included articles with 27 articles (54%). The proximal humerus was the most commonly explored HF location in our study (72%). The average MCMS and Methodological Index for Non-randomized Studies scores were reported to be 64.6 and 10.4, respectively, and the majority of articles (52%) were considered level four case series. Year of publication was found to have a positive correlation with increasing level of evidence(r=-0.301, P=.044), citation density (r= 0.734, P < .001), and MCMS score (r= 0.41, P= .01). The level of evidence, MCMS scores, and citation density of influential HF literature has been increasing with time, reflecting the increasing effort and work being put in that field. While the findings seem encouraging, additional high-quality research is needed to help achieve better treatment strategies and outcomes.

Arthroscopic Latarjet Versus Arthroscopic Free Bone Block Procedures for Anterior Shoulder Instability: A Proportional Meta-analysis Comparing Recurrence, Complication, and Reoperation Rates.

Several arthroscopic glenoid bone augmentation techniques have been introduced to treat patients affected by anterior shoulder instability associated with critical bone loss. The efficacy of the different arthroscopic bony procedures has not been compared yet. To compare the recurrence, complication, and reoperation rates of the arthroscopic Latarjet (AL) and arthroscopic free bone block (ABB) procedures for anterior shoulder instability. Meta-analysis and systematic review; Level of evidence, 4. A systematic search was conducted in MEDLINE/PubMed, Web of Science, and Embase to identify clinical studies reporting the outcomes of the AL and ABB procedures. The following search phrases were used: "Arthroscopic" AND "Bone Block" OR "Bone Graft," and "Arthroscopic" AND "Glenoid Augmentation" OR "Glenoid Reconstruction," and "Arthroscopic" AND "Latarjet" OR "Coracoid Graft" OR "Coracoid Transfer." Exclusion criteria were <24 months of minimum follow-up, sample size <10 cases, revision after previous glenoid bone grafting, epilepsy, and multidirectional instability. Data regarding the study design, patient characteristics, surgical technique, and outcomes were extracted and analyzed. A proportional meta-analysis was conducted to compare the complication, recurrence, and reoperation rates between the 2 groups. Multiple subgroup analyses were performed to analyze the incidence of each complication and assess the weight of different fixation methods (in the whole cohort) or different graft types (in the ABB group). The modified Coleman Methodology Score was used to assess the risk of bias. Of 5010 potentially relevant studies, 18 studies regarding the AL procedure (908 cases) and 15 studies regarding the ABB procedure (469 cases) were included. The 2 groups were comparable in age (P = .07), sex (P = .14), glenoid bone loss (P = .14), number of preoperative dislocations (P = .62), proportion of primary and revision procedures (P = .95), length of follow-up (P = .81), modified Coleman Methodology Score (P = .21), and level of evidence (P = .49). There was no difference in the recurrence (P = .88), reoperation (P = .79), and complication (P = .08) rates. The subgroup analyses showed a higher rate of hardware-related complications for screw fixation compared with flexible fixation (P = .01). The AL and ABB procedures had similar recurrence, reoperation, and complication rates. Screw fixation of the bone graft was related to an increased risk of complications compared with flexible fixation. CRD42022368153 (PROSPERO).

Outcomes following total ankle total talus replacement: A systematic review

BackgroundProsthetic substitution of the talus presents a significant challenge to the foot and ankle surgeon. The shear and compressive forces on the talus and its tenuous blood supply lead to high rates of avascular necrosis and eventual talar collapse. The purpose of this systematic review is to evaluate whether total ankle total talus replacement (TATTR) leads to improved clinical and radiographic outcomes with appropriate safety metrics in patients with a history of avascular necrosis or significant trauma. MethodsWe searched the concepts of talus, prosthesis, and arthroplasty in MEDLINE (PubMed), Embase (Elsevier), CINAHL Complete (EBSCOhost), and Scopus (Elsevier) from the database's inception through March 9, 2023. Inclusion Criteria were 1) previous trauma to the talus, 2) post-traumatic arthritis to the tibiotalar joint, 3) avascular necrosis of talus, 4) multiple failed prior interventions, 5) degenerative osteoarthritis to the tibiotalar joint, and 6) inflammatory arthropathy to tibiotalar joint. Patients less than 18 years of age and manuscripts in non-English languages were excluded. ResultsOf the 7625 references, 16 studies met the inclusion criteria, yielding data from 136 patients (139 ankles). The studies varied in design, with case reports and retrospective case series being predominant. The overall weighted average modified Coleman Methodology Score (mCMS) was 70.4 out of 100, indicating moderate flaws in study design that may be subject to various forms of bias and possible confounders. Demographics showed a diverse range of etiologies, with alumina ceramic being the primary prosthesis material. Functional scores demonstrated improvements in dorsiflexion and plantarflexion, although patient-reported outcome measures (PROs) were inconsistently reported. Complications included fractures, heterotopic ossification, prolonged wound healing, and infections. Revision details were sparsely reported. ConclusionTATTR is a promising treatment modality for improving short-term functional outcomes for patients with avascular necrosis or trauma-related issues. However, this systematic review underscores the need for standardized reporting, longer-term follow-ups, and further research to establish the procedure’s efficacy and safety, particularly in comparison to other treatment modalities.

Evidence-Based Approaches to Anticoagulation in Reconstructive Microsurgery-A Systematic Literature Review.

This systematic review addresses the crucial role of anticoagulation in microsurgical procedures, focusing on free flap reconstruction and replantation surgeries. The objective was to balance the prevention of thrombotic complications commonly leading to flap failure, with the risk of increased bleeding complications associated with anticoagulant use. A meticulous PubMed literature search following Evidence-Based-Practice principles yielded 79 relevant articles, including both clinical and animal studies. The full-texts were carefully reviewed and evaluated by the modified Coleman methodology score. Clinical studies revealed diverse perioperative regimens, primarily based on aspirin, heparin, and dextran. Meta-analyses demonstrated similar flap loss rates with heparin or aspirin. High doses of dalteparin or heparin, however, correlated with higher flap loss rates than low dose administration. Use of dextran is not recommended due to severe systemic complications. In animal studies, systemic heparin administration showed predominantly favorable results, while topical application and intraluminal irrigation consistently exhibited significant benefits in flap survival. The insights from this conducted systematic review serve as a foundational pillar towards the establishment of evidence-based guidelines for anticoagulation in microsurgery. An average Coleman score of 55 (maximum 103), indicating low overall study quality, however, emphasizes the need for large multi-institutional, randomized-clinical trials as the next vital step.

Effect of Various Ancillary Operating Room Techniques on Wound Healing Outcomes After Total Knee Arthroplasty.

The successful management of wound healing after total knee arthroplasty (TKA) depends on several aspects of ancillary intraoperative techniques and surgical variables. Many of these have been evaluated in a few recent reports. The prior reviews studied many aspects of wound healing and, for example, found lower risks of wound complications with barbed sutures compared with interrupted closure with non-barbed sutures, no differences in wound complications between adhesives, subcuticular sutures, staples, glue, or mesh adhesives for the closure of the skin layer, and that mesh adhesives may be associated with faster closing times compared to subcuticular sutures or staples in TKA. However, some topics that can be influenced by the surgeon were not covered in these previous reviews. Namely, the use of deep vein thrombosis (DVT) prophylaxis, tourniquet application, management of intraoperative drains, surgical approach selection, and patellar handling techniques can all potentially influence wound healing. Therefore, in this comprehensive systematic review of the literature, we focused on these five factors that may influence wound healing. Specifically, we evaluated: (1) the impact of different DVT prophylaxis methods on wound healing and infection rates; (2) the role of tourniquet application on wound closure and potential infection risks; (3) the effects of intraoperative drain usage on wound healing; (4) the influence of different surgical approaches on wound closure and postoperative infection rates; and (5) the effects of varying patellar handling strategies on wound healing and infection rates. A systematic search of electronic databases, including PubMed, Cochrane Library, Medline, and Embase, was conducted to identify studies assessing auxiliary surgical techniques and their impact on wound healing in total knee arthroplasty (TKA). Relevant terms like "knee," "arthroplasty," and "wound healing" refined the search, which included English language publications until May 1, 2023. Independent screening by two authors and a third mediator facilitated the selection process, with 24 studies meeting the criteria. Assessment of these studies involved evaluating their evidence level and methodological quality using the Modified Coleman Methodology Score (MCMS). A comparison was made on wound healing outcomes in TKA, which included evaluating methodological quality parameters like sample sizes, follow-up durations, and clinical effect measurements. Data synthesis for the studies provided a comprehensive summary, categorizing them by evidence level. There were seven reports on DVT prophylaxis that showed no statistically significant differences in wound complications among various treatment methods and medications in patients undergoing total knee arthroplasty (TKA), with wound complication rates ranging from 0.25 to 1%, except that aspirin appeared to have lower wound complications rates in three recent studies than other methods. There were five reports on tourniquet application that showed a generally increased rate of wound complications, but no increase in deep infections. The five reports on intraoperative drain use showed that while there is an increase in total blood loss in the group with drains, ranging from 568ml to 1,856ml, compared to 119ml to 535ml in the no-drain group, there are no significant differences in wound complications, infection rates, or other postoperative outcomes such as swelling, deep vein thrombosis, and range of motion between the drain and no-drain groups. There were three studies on surgical approaches revealing no differences in wound complication rates between the mini-subvastus and medial parapatellar incisions. Also, the surgical variables of patella eversion and anterior tibial translation were only studied in one report. The current literature highlights the importance of using aspirin when possible for DVT prophylaxis and the possibility that tourniquets may lead to increased superficial wound complications. Drains or surgical approach do not appear to lead to wound problems. Surgical variables, such as patella eversion and anterior tibial translation, need more study.

Effect of Various Ancillary Operating Room Techniques on Wound Healing Outcomes After Total Hip Arthroplasty.

The successful management of wound healing following total hip arthroplasty (THA) is multifaceted, relying on various intraoperative techniques and surgical variables. Recent reviews have evaluated many of these factors, including the comparison between mesh-adhesive dressings and other skin closure methods, the closing time of different suture techniques, and the four aspects of closure for THA (deep fascial layer; subdermal layer; intradermal layer). However, previous articles did not cover certain topics that can be directly influenced by the surgeon. Specifically, these include the use of deep vein thrombosis (DVT) prophylaxis, the management of intraoperative drains, and the selection of surgical approaches. Therefore, in this comprehensive systematic review of the literature, we have focused on three factors that may influence wound healing. We evaluated the following: (1) the impact of different DVT prophylaxis methods on wound healing and infection rates; (2) the effects of intraoperative drain use on wound healing; (3) the influence of various surgical approaches on wound closure, and postoperative infection rates. By concentrating on these areas, this review aims to provide a more complete understanding of the factors that contribute to successful wound management after THA. A systematic search of electronic databases, including PubMed, Cochrane Library, Medline, and Embase, was conducted to identify studies assessing surgical variables and techniques, specifically focusing on DVT prophylaxis, intraoperative drain use, and surgical approaches and their impact on wound healing in THA. Relevant terms like "hip," "arthroplasty," "wound healing," "DVT prophylaxis," and "surgical approaches" refined the search, which included English language publications until May 1, 2023. Independent screening by two authors and a third mediator facilitated the selection process, with 13 studies meeting the criteria. Assessment of these studies involved evaluating their evidence level and methodological quality using the Modified Coleman Methodology Score (MCMS). A comparison was made on wound healing outcomes in THA, specifically focusing on the three factors outlined in the introduction: (1) the impact of different DVT prophylaxis methods on wound healing and infection rates; (2) the effects of intraoperative drain use on wound healing; and (3) the influence of various surgical approaches on wound closure and postoperative infection rates. Data synthesis for the studies provided a comprehensive summary, categorizing them by evidence level, and aimed to contribute to a more complete understanding of the factors that influence successful wound management after THA. In studies examining DVT prophylaxis for total knee arthroplasties (TKA), three reports found that both rivaroxaban and enoxaparin had similar wound infection rates at 0.36%. However, one study segment suggested a slightly higher infection rate for rivaroxaban at 0.71% compared to enoxaparin's 0.49%. Despite this difference, it was not statistically significant (odds ratio [OR] 1.34, 95% confidence interval [CI] 0.46 to 3.86). In recent research, a low dose of aspirin has been observed to yield fewer wound complications when contrasted with other techniques. Five studies on intraoperative drain use revealed mixed outcomes. A total of five studies were identified that evaluated wound complications with drains following THA, comprising two randomized controlled trials (RCTs) and three observational cohort studies, with a combined sample size of 765. Among these, four studies specifically compared the use of closed suction drains to no drains. Half of these studies (two out of four) reported no significant differences in wound complications between the two groups, while the other half presented mixed findings. In surgical approach comparisons by Jin et al., meta-analysis between the direct anterior approach (DAA) and posterolateral approach (PLA) showed no significant difference in complications (OR 0.57, p=0.952). Two studies analyzed bikini incision DAA versus PLA or conventional DAA, indicating comparable outcomes with no significant differences in wound complications between the approaches and no major variations in healing, acute PJI, or dysesthesia when comparing bikini incision DAA to conventional DAA. Wound healing post THA is a complex process, influenced by various surgical techniques and intraoperative decisions. This systematic review meticulously examined three critical factors: the role of DVT prophylaxis, the implications of intraoperative drain usage, and the impact of different surgical approaches. Our analysis revealed that rivaroxaban and enoxaparin exhibit similar wound infection rates in THA. The decision to use intraoperative drains in the current literature indicates no definite advantage or disadvantage regarding wound problems with the use of closed-suction drainage in THA. In exploring surgical methodologies, the DAA and the PLA showed comparable complication rates. Yet, specific techniques within the DAA category demonstrated variations in delayed wound healing, particularly among obese patients. These findings emphasize the nuanced role of surgical choices in determining wound healing outcomes. As the field of THA continues to evolve, it becomes important for surgeons to be well-informed, ensuring optimal patient outcomes.

Does Tibial Tuberosity Osteotomy Improve Outcomes When Combined With Medial Patellofemoral Ligament Reconstruction in the Presence of Increased Tibial Tuberosity-Trochlear Groove Distance? A Systematic Review and Meta-analysis.

There has been recent debate regarding the optimal surgical management strategy for recurrent patellofemoral instability in the presence of an increased tibial tuberosity-trochlear groove (TT-TG) distance. In particular, performing a combined tibial tuberosity osteotomy (TTO) and medial patellofemoral ligament reconstruction (MPFLR) for patients with a TT-TG >20 mm has been questioned, with the hypothesis that an isolated MPFLR (iMPFLR) would be just as effective. To pool and compare outcomes after MPFLR+TTO versus iMPFLR in patients with a TT-TG >20 mm. Systematic review; Level of evidence, 4. PubMed-MEDLINE, Embase, Web of Science, and Cochrane Central were searched, and a systematic review was performed. Included were studies that reported postoperative redislocation rates and/or functional outcome scores for patients with recurrent patellar instability and a TT-TG >20 mm who underwent either MPFLR+TTO or iMPFLR and had minimum 2-year follow-up data. Methodologic quality was assessed using the modified Coleman Methodology Score (mCMS). A proportional meta-analysis comparing redislocation, subjective instability, and total complication rates was performed, and mean postoperative functional outcome scores were pooled using a random-effects model with a restricted maximum likelihood estimator. In total, 1548 studies were screened, from which 13 were included for analysis. Of the 386 included patients (406 knees), 276 underwent MPFLR+TTO and 110 underwent iMPFLR. The mean mCMS was 61.3 ± 10.5 (range, 48-77). The pooled postoperative redislocation rate was 1.22% (95% CI, 0.22%-7%), with no significant difference between the study groups (P = .9995). The pooled complication rate was 10.17% (95% CI, 6.2%-16.3%) with no difference between groups (P = .9275), although the MPFLR+TTO group had higher heterogeneity in complication rates (I2 = 79.4%) compared with iMPFLR (I2 = 0%). There was no group difference in the pooled postoperative Lysholm scores (P = .5177), but patients who underwent iMPFLR had significantly higher postoperative Kujala scores compared with those who underwent MPFLR+TTO (P = .0283). Even in the presence of previously indicative anatomic factors (TT-TG >20 mm), TTO combined with MPFLR does not seem to confer additional benefit compared with iMPFLR. This finding could be advantageous in minimizing the burden of additional surgery with its associated risks. The study findings should, however, be interpreted with caution given the heterogeneity of the studies.

Correction of symbrachydactyly: a systematic review of surgical options

Symbrachydactyly is a rare congenital malformation of the hand characterized by short or even absent fingers with or without syndactyly, mostly unilaterally present. The hand condition can vary from a small hand to only nubbins on the distal forearm. This study aims to systematically review the surgical management options for symbrachydactyly and compare functional and aesthetic outcomes.The review was performed according to the PRISMA guidelines. Literature was systematically assessed searching the Cochrane Library, PubMed, Embase, and PROSPERO databases up to January 1, 2023. Studies were identified using synonyms for ‘symbrachydactyly’ and ‘treatment’. Inclusion criteria were the report of outcomes after surgical treatment of symbrachydactyly in humans. Studies were excluded if they were written in another language than English, German, or French. Case reports, letters to the editor, studies on animals, cadaveric, in vitro studies, biomechanical reports, surgical technique description, and papers discussing traumatic or oncologic cases were excluded.Twenty-four studies published were included with 539 patients (1037 digit corrections). Only one study included and compared two surgical techniques. The quality of the included studies was assessed using the Modified Coleman Methodology Score and ranged from 25 to 47. The range of motion was the main reported outcome and demonstrated modest results in all surgical techniques. The report on aesthetics of the hand was limited in non-vascularized transfers to 2/8 studies and in vascularized transfers to 5/8 studies, both reporting satisfactory results. On average, there was a foot donor site complication rate of 22% in non-vascularized transfers, compared to 2% in vascularized transfers. The hand-related complication rate of 54% was much higher in the vascularized group than in the non-vascularized transfer with 16%.No uniform strategy to surgically improve symbrachydactyly exists. All discussed techniques show limited functional improvement with considerable complication rates, with the vascularized transfer showing relative high hand-related complications and the non-vascularized transfer showing relative high foot-related complications.There were no high-quality studies, and due to a lack of comparing studies, the data could only be analysed qualitatively. Systematic assessment of studies showed insufficient evidence to determine superiority of any procedure to treat symbrachydactyly due to inadequate study designs and comparative studies. This systematic review was registered at the National Institute for Health Research PROSPERO International Prospective Register of Systematic Reviews number: CRD42020153590 and received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors.Level of evidenceI.Systematic review registrationPROSPERO CRD42020153590.

Reverse or Ulnar-Sided, Greater Arc Perilunate Injury: Case Report and Systematic Review of Literature.

Perilunate injuries of carpal bones are uncommon, high-energy injuries that necessitate early diagnosis and appropriate management to prevent progressive carpal instability and posttraumatic osteoarthritis. A much more uncommon mechanism that starts from the lunotriquetral ligament and proceeds radially in an opposite direction than the classic mechanism may cause a reverse or ulnar-sided perilunate dislocation (PLD). The purposes were: (1) to present an uncommon case of greater arc reverse (ulnar-sided) perilunate fracture-dislocation (REPLFD); and (2) to conduct a systematic review (SR) to evaluate the current evidence on reverse perilunate injuries (REPLIs). A novel pattern of injury of REPLFD with fractures of the ulnar styloid, triquetrum, and capitate is presented. A SR was conducted with primary outcome measures of the type of injury (pathoanatomy of lesions) and pathomechanics. Secondary outcome measures were choice of surgery and outcome on follow-up. The Murad's tool and modified Coleman Methodology Score revealed poor methodological quality of the available literature on REPLI. Evidence is lacking in the mechanism of injury and treatment of REPLI, especially regarding REPLFD. The SR revealed poor methodological quality of the available literature and exposes that not all PLDs can be explained by the current existing pathomechanical injury classifications. However, following the management principles of perilunate injuries, REPLI tends to have good functional results with no major complications. Level V.

Role of fibular autograft in ankle arthrodesis fixed using cannulated screws: a proportional meta-analysis and systematic review

Ankle arthrodesis is commonly performed to treat end-stage ankle osteoarthritis. The aim of this study was to determine whether the use of fibular autograft might increase the fusion rate and decrease the complication rate in ankle arthrodesis (AA) fixed using cannulated screws. To perform this PRISMA-compliant proportional meta-analysis, multiple databases were searched for studies in which patients undergone AA (using exclusively cannulated screws and augmented with fibular bone graft) were followed. The characteristics of the cohort, the study design, surgical details, the nonunion and complication rate at the longest follow-up were extracted and recorded. The modified Coleman Methodology Score (mCMS) was applied to appraise the quality of studies. Two groups were built: arthrodeses fixed with screws combined with cancellous autograft (G1) and arthrodeses fixed with screws combined with cancellous autograft and augmented with a lateral fibular onlay (G2). A third group (arthrodeses fixed with screws and no graft, G3) was extracted from previous literature for a further comparison. Overall, we included 306 ankles (296 patients) from ten series (ten studies). In G1 and G2 there were 118 ankles (111 patients) and 188 ankles (185 patients), respectively. In patients where cancellous autograft was used, a further augmentation with a fibular lateral strut autograft did not change significantly the nonunion (4% [95% CI 1–9] in G1 vs. 2% [95% CI 0–5) in G2, p = 0.99) nor the complication rate (18% [95% CI 0–36] in G1 vs. 13% [95% CI 6–21) in G2, p = 0.71). Upon comparison with 667 ankles (659 patients, G3) in which arthrodeses had been performed without grafting, the nonunion and complication rates did not differ significantly either (pooled estimates: 3% [95% CI 1–3) in G1 + G2 vs. 3% [95% CI 2–4] in G3, p = 0.73 for nonunion; 15% [8–23] in G1 + G2 vs. 13% [95% CI 9–17] in G3, p = 0.93 for complications). In ankle arthrodesis fixed with cannulated screws combined with cancellous autograft at the fusion site, a construct augmentation with a distal fibular onlay strut graft positioned laterally at the ankle joint does not reduce the risk of nonunion or complication. In general, the use of bone graft does not influence significantly the nonunion nor the complication rate as compared to non-grafted screw-fixed ankle arthrodeses.Kindly check and confirm the corresponding author mail id is correctly identified.It's all correct

Assessment and trends in the methodological quality of the top 50 most cited articles in shoulder arthroplasty

IntroductionShoulder arthroplasty is increasingly frequent, and the associated literature is abundant. Citation rate is often considered a good means of assessing impact and scientific value. However, analysis of methodological quality is also essential in evidence-based medicine. Objectives(1) To identify the 50 most cited articles on shoulder arthroplasty, and (2) to assess the correlation between citation rate and methodological quality. The study hypothesis was that there is no correlation between citation rate and methodological quality. MethodArticles were retrieved from PubMed and Google Scholar, identifying the 50 most cited articles on shoulder arthroplasty via the keywords “shoulder joint replacement”, “shoulder arthroplasty”, “anatomic shoulder prothesis”, “reverse shoulder prothesis”, and “glenohumeral arthritis”. Modified Coleman Methodology Score (MCMS) and the Methodological Index for Non-Randomized Studies (MINORS) were calculated. ResultsMean citation rate for the 50 articles was 312.4±169.5 (range, 151–841.5), with a mean citation density of 18.8±10.6 (range, 4.7–46.7). 56% of the studies (28/50) were retrospective case series with level of evidence IV. There was no correlation between citation rate and methodological quality. DiscussionThe 50 most cited articles on shoulder arthroplasty mostly showed low levels of methodological quality. There was no correlation between citation rate and methodological quality: the literature needs to be read with a critical eye. Level of evidenceIV.

Corticosteroid injections for the treatment of lateral epicondylitis are superior to platelet rich plasma at 1 month but platelet rich plasma is more effective at 6 months: An updated systematic review and meta-analysis of level 1 and 2 studies.

The purpose of this study was to perform a systematic review and meta-analysis of studies comparing local injections of either platelet-rich plasma (PRP) or corticosteroid for the treatment of lateral elbow epicondylitis. A systematic review of Medline, Embase, Scopus, and Google Scholar was performed, and all level 1 and 2 randomized studies from 2000 to 2022 were included. Clinical symptoms, patient perceived outcomes, and pain were assessed by the DASH (disabilities of the arm, shoulder and hand questionnaire) and pain by the VAS (visual analog scale). Publication bias and risk of bias were assessed using the Cochrane Collaboration's tools. The modified Coleman Methodology Score (CMS) and the GRADE system were used to assess the quality of the body of evidence. Heterogeneity was assessed using χ2 and I2 statistics. Thirteen studies were included in the analysis. Five studies had a high risk of bias, and the risk of bias across studies was assessed as unclear. There was no publication bias identified. Two of the four GRADE domains (inconsistency of results, imprecision of results) were downgraded to low quality, and the final GRADE assessment was downgraded to a low quality of evidence. The mean CMS score was 62.8, indicating fair quality. The pooled estimate for VAS at 1 month favored corticosteroids (p=0.75), but favored PRP at three (p=0.003) and six months (p=0.0001). The pooled estimate for the DASH score favored corticosteroids at 1 month (p=0.028), but favored PRP at three (p=0.01) and six months (p=0.107) CONCLUSION: The results of this meta-analysis suggest that PRP has no advantage over steroid injections within the first month of treatment, but that it is superior to steroids at both 3 and 6 months. These results also suggest that corticosteroids have a short-term beneficial effect during the early treatment period, although the quality of the available evidence is not very robust in support of this finding. However, these findings must all be viewed with caution as the high risk of bias and moderate to low quality of the included studies may not justify a recommendation of one treatment over another.

A Systematic Review of the Biomechanical Studies on Shoulder Kinematics in Overhead Sporting Motions: Types of Analysis and Approaches

The shoulder is a unique and complex joint in the human body with three bones and four joints, which makes it the most unstable joint in the body due to the amount of motion. To improve approaches toward understanding the performance of overhead throwing movements, this systematic review summarizes the type of analysis related to shoulder biomechanics involving overhead sporting motions. A search of seven databases identified 33 eligible studies, which were subsequently scored using the Modified Coleman Methodology Score scale. A total of nine articles from badminton, seven from baseball, five from volleyball, five from tennis, three from cricket, and one from softball were reviewed. All 33 studies evaluated shoulder kinematics and 12 of them also investigated the forces and torques (kinetics). The most common methods used were 3D motion analysis (76%), digital video cameras (15%), electromagnetic tracking system (6%), and finally 3% used IMU sensors. Overall, shoulder external rotation during the back swing, internal rotation, and elbow extension during the forward acceleration phase were the strongest predictors of high velocity overhead throwing movement. The findings provide some useful insights and guidance to researchers in their future contribution to the existing body of literature on shoulder overhead throwing movement biomechanics.

A Worldwide Analysis of Adipose-Derived Stem Cells and Stromal Vascular Fraction in Orthopedics: Current Evidence and Applications.

The biological enhancement of tissue regeneration and healing is an appealing perspective in orthopedics. We aimed to conduct a systematic review to describe the global distribution of studies investigating the use of adipose tissue derivates in orthopedics and to provide information on their quality and on the products available. The quality of the included studies was assessed using the modified Coleman Methodology Score (mCMS) and the Cochrane risk-of-bias tool for randomized trials. Eighty-two studies were included, with a total of 3594 patients treated. In total, 70% of the studies investigated the treatment of knee disorders, predominantly osteoarthritis; 26% of all studies dealt with expanded adipose-derived stem/stromal cells (ADSCs), 72% of which had stromal vascular fraction (SVF); 70% described the injection of adipose tissue derivates into the affected site; and 24% described arthroscopies with the addition of adipose tissue derivates. The mean mCMS for all studies was 51.7 ± 21.4 points, with a significantly higher score for the studies dealing with expanded ADSCs compared to those dealing with SVF (p = 0.0027). Our analysis shows high heterogeneity in terms of the types of performed procedures as well as the choice and processing of adipose tissue derivates.

Poster 357: Tranexamic Acid in Foot and Ankle Surgery: A Systematic Review and Meta-analysis

Objectives: Tranexamic acid (TXA) use has become common in Orthopedic surgeries. Despite the growing number of publications related to its use, no recent systematic reviews have been published examining TXA use in foot and ankle surgery. The aim of this review article is to provide a summary of the current available literature regarding TXA use in foot and ankle surgery and to further the understanding of its safety and efficacy. Methods: This was a systematic review following the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines as outlined on the PRISMA checklist. Databases utilized included PubMed, Ovid, CINAHL, Clinical Key, Medline, and Embase, and the search was conducted through May 21, 2022. Key words used in the search included: “tranexamic acid,” “TXA,” “foot,” “ankle,” “calcaneal,” and “surgery.” The outcomes within the studies analyzed included measures of perioperative blood loss (intra-operative blood loss, 24-hour postoperative blood loss, blood loss from hour 24 to hour 48, postoperative hemoglobin (Hgb), and postoperative hematocrit (Hct)), as well as wound complications and vascular events. Wound complications and vascular events were defined as infection, hematoma formation, necrosis, dehiscence, DVT, PE, myocardial infarction (MI), acute coronary syndrome (ACS), cardiovascular event (CVA), limb ischemia (LI), gastrointestinal hemorrhage (GIH), nerve damage, and any other conditions specified as wound complications or vascular events within individual studies. The Cochrane Collaboration’s Risk of Bias 2 (RoB2) tool was used to assess the risk of bias in the studies included. The quality of the studies included was scored using a modified Coleman methodology score (MCMS). Primary treatment outcomes having data from three or more studies available were summarized in forest plots using RevMan 5.4.1 software (The Cochrane Collaboration, Copenhagen, Denmark). Random-Effects models were used to calculate mean differences with 95% confidence intervals for each outcome measure. Heterogeneity of studies was assessed using Tau2, Chi2, and I2 statistics. Statistical significance was set at α=0.05 for all comparisons. Results: The literature search produced 1125 papers. The full texts of 16 studies were assessed using inclusion and exclusion criteria and seven studies met preliminary inclusion criteria. Upon further inspection, five met full inclusion criteria for the meta-analysis. All groups receiving TXA had statistically significantly lower blood loss values at 24 hours. One study found a statistically significant increase in blood loss from 24-48 hours in their A group (TXA) versus non-TXA. Three study groups demonstrated statistically significantly higher values of postoperative hemoglobin in patients receiving TXA versus patients not receiving TXA. Three study groups demonstrated statistically significantly higher values of postoperative hematocrit in patients receiving TXA versus patients not receiving TXA. No studies found statistically significant differences in wound complications between TXA and non-TXA groups. Conclusions: Despite a growing amount of literature on the topic, there is still a paucity of literature published on TXA use in foot and ankle surgery. Additional literature is required to determine the best strategy for TXA use to optimize patient outcomes. Current literature suggests that foot and ankle surgery patients treated with TXA may have reduced 24-hour postoperative blood loss, increased postoperative hemoglobin and hematocrit when compared to similar patients not receiving TXA. The use of TXA in foot and ankle surgery did not lead to increased thromboembolic complications.
