Effect of collagen supplementation on knee osteoarthritis: an updated systematic review and meta-analysis of randomised controlled trials.

OBJECTIVES: To perform a systematic review and meta-analysis to assess the clinical efficacy of collagen-based supplements on knee osteoarthritis (OA) symptoms. METHODS: Until October 2023, we conducted searches on the MEDLINE, EMBASE, Web of Science, and Scopus databases to identify randomised controlled trials (RCTs) that reported the effects of oral collagen-based supplements on knee OA. Quantitative data from outcomes were pooled using a random- or fixed-effects model (depending on inter-study variability) and the generic inverse variance method. The Cochrane Risk of Bias 2.0 tool was employed to assess the risk of bias. RESULTS: This systematic review incorporated information of 870 participants included from 11 RCTs, with 451 allocated to the collagen supplementation group and 419 to the placebo group. The meta-analysis revealed an overall significant improvement of both function [MD, -6.46 (95% CI -9.52, -3.40); I2=75%; p=0.00001] and pain scores [MD, -13.63 (95% CI -20.67, -6.58); I2=88%; p=0.00001], favouring collagen supplementation. CONCLUSIONS: The results of this meta-analysis suggest that oral collagen administration relieves OA symptoms. Our findings revealed noteworthy improvements, statistically and clinically, in both functional and pain scores.

A comparison of three techniques for the osteosynthesis after minimal invasive osteotomies for hallux valgus.

PURPOSE: Third and fourth-generation minimal invasive osteotomies (MIO) for the treatment of hallux valgus (HV) have become popular procedures worldwide with promising results due to the improvement in the fixation method. The tricortical cannulated screw placement remains a complex procedure that is technically challenging and requires a long skill learning curve with high radiation exposure mainly in the form of intensifier shots (IS) required for the MIO fixation. This study aims to compare the number of X-ray IS required using three different techniques for the cannulated guide placement. METHODS: A retrospective cross-sectional observational and comparative study was conducted to assess the number of X-rays IS required for correct cannulated screw guide placement using three different techniques: traditional perforator, the drill and joystick, and K-wire first techniques. RESULTS: A total of 53 MIS procedures from thirty-one patients in two different hospitals were included. IS X-rays were 155.1 ± 29.7 in the traditional technique (n = 14), 143.0 ± 43.2 in the drill and joystick technique (n = 22), and 85 ± 18.7 in the K-wires first technique (n = 17), p = < 0.001 using one-way ANOVA. CONCLUSIONS: The K-wire first technique statistically significantly decreases X-ray IS numbers p ≤ 0.001. There were no statistically significant differences between the traditional (after osteotomy K-wire placement) and the drill and joystick techniques (p = 0.36).

Effect of extracorporeal shockwave therapy on plantar fascia thickness in plantar fasciitis: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: Extracorporeal shockwave therapy (ESWT) has been used as a therapeutic option for plantar fasciitis. The objective was to investigate the effect of ESWT over the plantar fascia thickness. METHODS: MEDLINE, Embase, Web of Science, and SCOPUS databases were searched for randomized controlled trials evaluating the effect of ESWT in patients with plantar fasciitis, comparing ESWT with another treatment. Meta-analysis was conducted using a random-effects model and the generic inverse variance method. Meta-regression and subgroup analyses were also carried out. RESULTS: A total of 14 studies (867 participants) were included. ESWT significantly decreased plantar fascia thickness (weighted mean difference [WMD], -0.21 mm [95% CI -0.39, -0.02]; p = 0.03). No significant improvement in pain was observed (WMD, -0.51 cm [95% CI -1.04, 0.01]; p = 0.06) compared with non-surgical interventions. CONCLUSIONS: Our results suggest that plantar fascia thickness is significantly decreased after ESWT intervention in patients with plantar fasciitis. However, pain relief was not significantly improved compared to other non-surgical interventions.

Effect of Adipose-Derived Mesenchymal Stem Cells (ADMSCs) Application in Achilles-Tendon Injury in an Animal Model.

Background: Achilles-tendon rupture prevails as a common tendon pathology. Adipose-derived mesenchymal stem cells (ADMSCs) are multipotent stem cells derived from adipose tissue with attractive regeneration properties; thus, their application in tendinopathies could be beneficial. Methods: Male rabbit ADMSCs were obtained from the falciform ligament according to previously established methods. After tenotomy and suture of the Achilles tendon, 1 × 106 flow-cytometry-characterized male ADMSCs were injected in four female New Zealand white rabbits in the experimental group (ADMSC group), whereas four rabbits were left untreated (lesion group). Confirmation of ADMSC presence in the injured site after 12 weeks was performed with quantitative sex-determining region Y (SRY)-gene RT-PCR. At Week 12, histochemical analysis was performed to evaluate tissue regeneration along with quantitative RT-PCR of collagen I and collagen III mRNA. Results: Presence of male ADMSCs was confirmed at Week 12. No statistically significant differences were found in the histochemical analysis; however, statistically significant differences between ADMSC and lesion group expression of collagen I and collagen III were evidenced, with 36.6% and 24.1% GAPDH-normalized mean expression, respectively, for collagen I (p < 0.05) and 26.3% and 11.9% GAPDH-normalized mean expression, respectively, for collagen III (p < 0.05). The expression ratio between the ADMSC and lesion group was 1.5 and 2.2 for collagen I and collagen III, respectively. Conclusion: Our results make an important contribution to the understanding and effect of ADMSCs in Achilles-tendon rupture.

Clinical Efficacy of Botulinum Toxin in the Treatment of Plantar Fasciitis: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

OBJECTIVE: To evaluate the efficacy of botulinum toxin A (BTX-A) for the treatment of plantar fasciitis through a meta-analysis of randomized controlled trials (RCTs) focusing on pain and functional outcomes since current literature has supported a potential benefit of BTX-A. DATA SOURCES: The MEDLINE, EMBASE, Web of Science, and Scopus databases were searched until December 2020 for RCTs reporting the effects of BTX-A injections on plantar fasciitis. The complementary literature search included Cochrane Central Register of Controlled Trials, Clinicaltrials.gov, and greylit.org. STUDY SELECTION: Only RCTs assessing the effect of BTX-A injections on pain, functional improvement, or plantar fascia thickness in patients with plantar fasciitis were included. Multiple researchers carried out the screening process of the 413 records. DATA EXTRACTION: Data were extracted independently and in duplicate using a standardized data extraction format. Information was contrasted by a third observer. DATA SYNTHESIS: BTX-A injections resulted in significant pain relief (mean difference, -2.07 [95% CI, -3.21 to -0.93]; P=.0004; I2=97%) and functional improvement (standardized mean difference, 1.15 [95% CI, 0.39-1.91]; P=.003; I2=87%). A subanalysis indicated that pain relief was sustained at 12 months while functional improvement remained significant after 0-6 months. The results were not affected by a single study after sensitivity analysis. The site of injection and the use or not of ultrasound-guided injections may account for potential sources of interstudy heterogeneity. CONCLUSIONS: This meta-analysis suggests both a statistically significant and a clinically meaningful improvement on plantar fasciitis symptoms after BTX-A treatment.

The morphology of the femoral footprint of the anterior cruciate ligament changes with aging from a large semicircular shape to a small flat ribbon-like shape.

PURPOSE: Compare the differences in the morphology of the ACL femoral footprint between the cadavers of the young and elderly in consideration of the degenerative physiological process that occurs with aging. METHODS: The femoral footprint of the ACL was dissected in 81 knees of known gender and age (45 male/36 female). They were divided into four groups by age and gender, establishing 50 years as the cut-off point to divide patients by age. Three observers analyzed the femoral footprint dissections, and the shapes were described and classified. The area and morphometric characteristics of the femoral insertion of the ACL were determined and these were compared between genders and age groups. RESULTS: The femoral footprint of the ACL from the cadavers of males younger than 50 years of age presented a semicircular morphology in 90% of the cases. In males aged more than 50 years, a ribbon-like morphology was found in 96% of the cases. In women less than 50 years old, the semicircular morphology was observed in 93.7% of the cases. In women aged over 50 years old, the ribbon-like morphology was found in 95% of the cases. A significant difference was observed between the prevalence rates of the morphologies, area size and measurements of the younger and older groups (p < 0.001 for both genders). CONCLUSIONS: The femoral insertion of the ACL presents variations in its morphology, area and morphometric characteristics over time. It goes from a large semicircular shape that almost contacts the posterior articular cartilage to a smaller, flattened ribbon-like shape that moves away from the edge of the articular cartilage. It is bounded anteriorly by the lateral intercondylar ridge. These findings should be considered to avoid employing reconstruction techniques in which femoral tunnels with oval or rectangular shapes are used in patients under 50 years of age because they do not correspond to the morphology of the femoral insertion of the ACL in this age group.

Fixed-bearing unicompartmental knee arthroplasty provides a lower failure rate than mobile-bearing unicompartimental knee arthroplasty when used after a failed high tibial osteotomy: a systematic review and meta-analysis.

Despite the fact that the choice of bearing design has been thought to influence the functional outcomes and longevity of unicompartimental knee arthroplasty (UKA), there is a lack of clinical evidence supporting the decision-making process in patients who have undergone high tibial osteotomy (HTO). A systematic review of studies was carried out that reported the outcomes of fixed-bearing (FB) or mobile-bearing (MB) medial UKA in patients with a previous HTO. A random effect meta-analysis using a generalized linear mixed-effects model to calculate revision rates was done. Seven retrospective cohort studies were included for this study. Regarding the fixation method, 40 were the FB-UKA and 47 were MB-UKA. For both groups, the mean post-operative follow-up was 5.8 years. The survival rates were 92% for the FB-UKA with a mean follow-up of 10 years. For the MB-UKA, it ranged from 35.7 to 93%, with a mean follow-up of 4.2 years. For the FB, the time to revision was reported as 9.3 years, while 1.2, 2.5 and 2.91 years was reported for the MB. The results of the meta-analysis showed that the revision rate for the patients receiving a FB-UKA after failed HTO was 8%, compared to 17% in those who received an MB-UKA. The results of the review suggest that the use of the FB-UKA is associated with lower revision rates and a longer survival time than the MB-UKA and have similar functional ability scores.Level of evidence: III (systematic review of level-III studies).

Distal radius fractures: Classifications concordance among orthopedic residents on a teaching hospital.

BACKGROUND: Several classification systems have been developed to support orthopedic surgeons regarding diagnostic, treatment, or prognostic outcomes of distal radius fracture (DRF). However, the best classification system for this fracture remains controversial. We aimed to identify the reliability of three different DRF classifications among orthopedists in training (medical residents). METHODS: Orthopedic residents (n = 22) evaluated thirty cases of DRF in anteroposterior and lateral projections in three different periods (0, 6, 12 months). Each radiography was sorted with three different classifications: Frykman, AO/OTA, and Jupiter-Fernandez. All assessments were blinded to the investigators. The inter- and intra-observer reliability was evaluated using the Cohen's kappa coefficient. An additional analysis was performed for a simpler sub-classification of the AO/OTA (27, 9, or 3 groups). RESULTS: Inter-observer agreement for AO/OTA, Frykman, and Jupiter-Fernandez classifications was slight (k = 0.15), fair (k = 0.31), and fair (k = 0.30), respectively. Intra-observer agreement showed similar results: AO/OTA, k = 0.14; Frykman, k = 0.28; and Jupiter-Fernandez, k = 0.28. When the AO/OTA classification was simplified (9 or 3 descriptions), the inter-observer agreement improved from slight (k = 0.16) to fair (k = 0.21 and k = 0.30, respectively). A similar improvement from slight (k = 0.14) to fair (k = 0.32 and k = 0.21) was detected for intra-observer agreement. CONCLUSIONS: The more complex the DRF classification system, the more complex is to reach reliable inter- and intra-observer agreements between orthopedic trainees. Senior residents did not necessarily show greater kappa values in DRF classifications.

The morphology of the tibial footprint of the anterior cruciate ligament changes with ageing from oval/elliptical to C-shaped.

PURPOSE: To further the current understanding of the modifications of the morphology of the ACL tibial footprint in healthy knees during the ageing process. The hypothesis is that there are differences in the morphology of the ACL tibial footprint between the cadavers of the young and elderly due to a degenerative physiological process that occurs over time. METHODS: The tibial footprint of the ACL was dissected in 64 knee specimens of known gender and age. They were divided into four groups by age and gender, setting 50 years of age as the cut-off point. Three observers analyzed the tibial footprint dissections and the shape was described and classified. RESULTS: The knees from the cadavers of males older than 50 years of age presented a "C" morphology in 85% of the cases. In the group of males aged less than 50 years, an oval/elliptical morphology was found in 85.7% of the cases. In the group of women over 50 years-old, the "C" morphology was observed in 82.3% of the cases. In women under the age of 50, the oval/elliptical morphology was found in 84.6% of the cases. A significant difference was observed between the prevalence rates of the morphologies of the younger and older groups (p < 0.001 for both genders). However, no differences were observed between males and females of the same age group (n.s.). CONCLUSIONS: The morphology of the tibial footprint of the ACL presents significant variations with ageing. It can go from an oval/elliptical shape to a "C" shaped morphology. The results of this work make for an advance in the individualization of ACL reconstruction based on the age and the specific morphology of the tibial footprint.

Treatment of lateral ankle sprain with platelet-rich plasma: A randomized clinical study.

BACKGROUND: We aimed to clinically evaluate the effect of platelet-rich plasma (PRP) therapy in patients with acute lateral ankle sprain treated with rigid immobilization. METHODS: Patients with first-time grade II lateral ankle sprain clinically diagnosed were evaluated (n=21). A rigid immobilization was placed in all patients for ten days; previously, an application of PRP over the anterior talofibular ligament was performed in patients from the experimental group. The Visual Analogue Scale, the American Orthopedic Foot and Ankle Score, and the Foot and Ankle Disability Index were applied at 3, 5, 8 and 24 weeks of follow-up period. RESULTS: The experimental group presented the highest reduction in pain and better functional scores than the control group at 8 weeks. At the end of follow-up period the results of both groups were similar. CONCLUSIONS: A similar evolution was observed in patients treated with rigid immobilization with or without PRP after 24 weeks. TRIAL REGISTRATION: Clinical Trials.gov with ID NCT02609308.

Effect of glucosamine and chondroitin sulfate in symptomatic knee osteoarthritis: a systematic review and meta-analysis of randomized placebo-controlled trials.

Although glucosamine and chondroitin sulfate have showed beneficial effects on joint tissues in osteoarthritis (OA), their therapeutic use in the clinical setting is still debatable. Hence, a systematic review and meta-analysis of randomized placebo-controlled trials was conducted to investigate the efficacy of glucosamine and chondroitin sulfate on knee OA symptoms. Medline, SCOPUS, Web of Science, and Google Scholar databases were searched for randomized placebo-controlled trials evaluating the effect of orally administered glucosamine and/or chondroitin sulfate on OA symptoms using the Western Ontario and McMaster Universities Osteoarthritis index (WOMAC) and/or the Visual Analog Scale (VAS). Meta-analysis was conducted using a random-effects model and generic inverse-variance method. Heterogeneity was tested using the I2 statistic index. Treatments with glucosamine and chondroitin were found to significantly reduce pain in VAS [weighted mean difference (WMD) - 7.41 mm, 95% CI - 14.31, - 0.51, p = 0.04 and WMD - 8.35 mm, 95% CI - 11.84, - 4.85, p < 0.00001, respectively]. Their combination did not show this behavior (WMD - 0.28 mm, 95% CI - 8.87, 8.32, p = 0.95). None of the glucosamine, chondroitin or their combination had a significant positive effect on the total WOMAC index and its subscores. Oral supplementation with glucosamine or chondroitin sulfate reduces pain in knee OA. However, there is no additional effect using both therapeutic agents in combination for the management of symptomatic knee OA.

Leukocyte-poor platelet-rich plasma is more effective than the conventional therapy with acetaminophen for the treatment of early knee osteoarthritis.

INTRODUCTION: Knee osteoarthritis (OA) is a degenerative and progressive articular cartilage disease. Infiltration of autologous platelet-rich plasma (PRP) has been proposed as a therapeutic alternative due to the content of biologically active cytokines in PRP. We aimed to compare the clinical response of acetaminophen and intra-articular leukocyte-poor PRP (LP-PRP) in early knee OA. MATERIALS AND METHODS: A total of 65 patients with clinically and radiographically documented knee OA (grade 1-2) were analyzed. Patients were randomized into two groups: 32 were treated with acetaminophen (500 mg/8 h) over 6 weeks, and 33 received three intra-articular injections of autologous LP-PRP (once every 2 weeks). All patients were evaluated by the Visual Analogue Scale (VAS), the Western Ontario and McMaster Universities (WOMAC) score, and the SF-12 health survey at baseline and 6, 12, and 24 weeks of follow-up. All LP-PRP preparations were analyzed for the platelet, leukocyte, IL-1ra, and TGF-ß concentrations. RESULTS: The decrease in the VAS pain level in the LP-PRP group was greater than that in the acetaminophen group (p < 0.05). Patients treated with LP-PRP showed a sustained improvement in knee function at week 24 (p < 0.01). The SF-12 results only indicated an improvement in quality-of-life in the LP-PRP group at 6, 12, and 24 weeks of follow-up (p < 0.01). Both IL-1ra and TGF-ß were detected in the LP-PRP samples (313.8 ± 231.6 and 21,183.8 ± 8556.3 pg/mL, respectively). CONCLUSIONS: Treatment with LP-PRP injections resulted in a significantly better clinical outcome than did treatment with acetaminophen, with sustained lower EVA and WOMAC scores and improvement in quality-of-life (higher SF-12 score). Therapy with LP-PRP may positively modify the inflammatory joint environment by counteracting IL-1ß action.

Genicular Nerve Block for Knee Osteoarthritis: A Systematic Review and Meta-analysis of Randomized Clinical Trials.

OBJECTIVES: Genicular nerve block (GNB) has emerged as a novel nonsurgical therapy for symptomatic knee osteoarthritis (KOA). The objective was to evaluate GNB versus placebo and other intra-articular (IA) therapies. METHODS: The Medline, Embase, and Scopus databases were searched from their inception to January 2021. Only randomized controlled trials (RCTs) were included. A random-effects model and the generic inverse variance method were used for quantitative data synthesis. Heterogeneity was tested with the I2 index. RESULTS: Regarding pain statistically significant scores were demonstrated at 1 and 3 months overall total effect of 1.43 (95% CI, 0.86, 1.99; P= 0.00001; I2 =85%). Similarly, for knee function a total effect of 0.71 (95% CI, 0.35, 1.06; P= 0.00001; I2 =69%) at 1 and 3 months, statistically significant. The minimal clinically important difference regarding pain was achieved at 1 and 3 months. DISCUSSION: Although, GNB achieved the MCID for KOA pain and statistically significant results for knee functions. We cannot recommend its routine use besides being a safe procedure so far, evidence is fair on GNB for primary KOA due to study heterogeneity and limited follow-up.

Effect of Topical Vancomycin on Surgical Site Infections in Ankle Fractures: A Randomized, Double-Blind, Controlled Trial.

Background Applying topical vancomycin has shown a decrease in the likelihood of surgical site infections (SSIs) in surgeries linked to a heightened risk of severe and resistant infections. Nevertheless, the effectiveness of this prophylactic approach has not been assessed in open ankle surgeries with internal fixation. Objective This study aimed to assess whether topical vancomycin diminishes the risk of SSI in patients with ankle fractures undergoing open reduction with internal fixation. Methods A randomized, controlled, double-blind clinical trial was carried out. Patients were divided into two groups in a 1:1 ratio. The control group received the standard prophylactic treatment with IV cephalothin 1 g, while the intervention group was administered topical vancomycin (1 g) in addition to the standard prophylactic treatment. The main outcomes were the SSI rates at 14 days, 28 days, and three months post-surgery, based on relevant clinical signs and laboratory tests. Results One hundred thirty-two patients were randomized (51.2% female), with 66 subjects included in each intervention arm. A total of 97.7% of them completed the study. Both groups were homogeneous in baseline characteristics. There were two SSIs in both the vancomycin group (3.3%) and the control group (3.5%), with no statistical differences (p = 0.945). The microorganisms isolated as causal agents were Staphylococcus aureus and Acinetobacter baumannii. By the three-month follow-up, no infections were noted in both intervention groups. Conclusion These results indicate that the topical administration of vancomycin may not represent an advantage in preventing SSI in ankle fractures requiring open reduction with internal fixation at the three-month postoperative stage.

Epidural administration of ropivacaine and midazolam is superior to intra-articular administration as postoperative analgesia after isolated arthroscopic anterior cruciate ligament reconstruction with hamstrings autograft: a randomized controlled clinical trial.

OBJECTIVE: Reconstructive surgery of the anterior cruciate ligament (ACL) is quite common, previous studies have documented that adequate pain control in the early phases of the postoperative period translates into early mobility and a rapid start of rehabilitation. Therefore, the search for new strategies for postoperative pain control is justified. The aim of this study was to compare intra-articular to the epidural administration of ropivacaine and midazolam as postoperative analgesia after arthroscopic ACL reconstruction with hamstring autograft (HA). MATERIAL AND METHODS: Double-blinded, prospective randomized clinical trial included 108 consecutive patients aged from 18 to 50 years that had undergone arthroscopic ACL reconstruction with HA. The patients were randomly assigned to 2 groups. The first group received intraarticular ropivacaine and midazolam. The second group received epidural ropivacaine and midazolam. The need for rescue analgesia, the postoperative pain experienced, side effects and complications of the analgesic drugs were evaluated. RESULTS: The intra-articular group received statistically significantly higher mean doses of rescue analgesia on the first two days (2.8 â€‹± â€‹1.0 vs. 1.3 â€‹± â€‹0.6 in the epidural group; p â€‹= â€‹0.001). Visual Analogue Scale scores at flexion were statistically significantly higher in the intra-articular group over the entire study period. The intra-articular group also reported a statistically significantly lower range-of-motion 87 â€‹± â€‹15 vs. 102 â€‹± â€‹11 in the epidural group (p â€‹= â€‹0.001). CONCLUSIONS: Epidural administration of ropivacaine combined with midazolam in patients undergoing primary ACL reconstruction with HA was clinically and significantly better relative to rescue analgesia and the intensity of pain in the first 48 postoperative hours when compared to intraarticular administration. There was no difference in terms of adverse effects and complications.

Clinical efficacy of botulinum toxin in lateral elbow tendinopathy: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Botulinum toxin injections for lateral elbow tendinopathy have been used as an alternative therapeutic option. However, few studies have quantitatively summarized the effect of botulinum toxin as well as its clinical significance. We aimed to evaluate the clinical efficacy (based on pain and grip strength) and adverse events of botulinum toxin on lateral elbow tendinopathy. PATIENTS AND METHODS: The MEDLINE, EMBASE, Web of Science, and Scopus databases were searched until March 2023 for randomized controlled trials reporting the effects of botulinum toxin injections on lateral elbow tendinopathy. A random- or fixed-effects model (depending of inter-study variability) and generic inverse variance method were used to pool quantitative data from outcomes. The risk of bias was assessed with the Cochrane Risk of Bias 2.0 tool. RESULTS: A total of 8 clinical trials recruiting 438 subjects were included for meta-analysis. Pooled analysis revealed that botulinum toxin significantly reduced pain (mean difference [MD] -0.95, 95% CI [-1.63, -0.26], p=0.007) but it was not clinically relevant. No significant effect was detected for grip strength (MD-0.62kg, 95% CI [-2.25, 1.02], p=0.46) or in the risk for adverse events (odds ratio [OR] 0.41, 95% CI [0.05, 3.56], p=0.42) between botulinum toxin injection and control interventions. DISCUSSION: The use of botulinum toxin reached greater pain relief than control interventions and normal saline after a period of 12 to 24 weeks. However, changes in pain relief did not reach clinical significance. The studies that had the greatest reduction in pain used higher doses of botulinum toxin (60 U). Additionally, differences in grip strength and adverse events did not reach statistical or clinical importance. A subanalysis indicated that botulinum toxin outperformed corticosteroid injections in terms of improving grip strength. Botulinum toxin only causes local and minimal side effects such as irritation, ecchymosis, and paralysis. LEVEL OF EVIDENCE: I.

Effect of corticosteroids over plantar fascia thickness in plantar fasciitis: a systematic review and meta-analysis.

OBJECTIVES: Corticosteroid injections have been typically used for the management of plantar fasciitis with apparently good clinical outcomes; however, there is no information of the effect of corticosteroids on the thickness of the plantar fascia which is typically altered in this pathology. We aimed determine whether treatment with corticosteroid injections induces plantar fascia thickness changes in plantar fasciitis. METHODS: MEDLINE, Embase, Web of Science, and Scopus databases were searched for randomized controlled trials (RCT) reporting the use of corticosteroid injection to treat plantar fasciitis to July 2022. Studies must have reported plantar fascia thickness measurement. The risk of bias in all studies was assessed with the Cochrane Risk of Bias 2.0 tool. Meta-analysis was conducted using a random-effects model and the generic inverse variance method. RESULTS: Data from 17 RCT (including 1109 subjects) were collected. The follow-up period ranged from one to six months. Most studies measured the thickness of the plantar fascia at the insertion into the calcaneus using ultrasound. Pooled analysis revealed that corticosteroid injections had no significant effect on plantar fascia thickness (weighted mean differences [WMD], 0.06 mm [95% CI: -0.17, 0.29]; p = 0.61) or pain relief (WMD, 0.12 cm [95% CI: -0.36, 0.61]; p = 0.62) above active controls. CONCLUSION: Corticosteroid injections do not perform better than other common interventions in terms of a decrease of plantar fascia thickness and pain relief for plantar fasciitis.

Open Inferior glenohumeral joint dislocation with complete range of motion recovery: Case Report and literature review.

Luxatio erecta is an inferior glenohumeral dislocation. It is an uncommon pathology with a prevalence of 0.5% of all shoulder dislocations. An open luxatio erecta presentation is rarer. After an extensive literature search, we only could find three complete case reports. From these cases, 2 out of 3 developed complications such as infections and severely limited range of motion, especially in flexion and abduction. We report the case of a 39-year-old man with an open inferior glenohumeral joint dislocation with complete rotator cuff tear and fracture of the greater tuberosity secondary to a motor vehicle accident. He was treated with open reduction, glenohumeral capsulorrhaphy, and transosseous rotator cuff repair with good clinical outcome. In conclusion, an open inferior shoulder dislocation is rare, less than 0.1% of all dislocations, with a high incidence of nerve injury. We suggest prompt surgical treatment with immediate administration of antibiotic therapy, wound debridement, irrigation, open reduction, and repair of the rotator cuff as an adequate protocol and focused rehabilitation with early mobilization of the glenohumeral joint.

Systemic and Local Cytokines Profile Determine Severity and Prognosis in Human Septic Arthritis.

BACKGROUND: Septic arthritis (SA) is a medical emergency. The most common etiological agents are bacteria, which activate the local immune response coordinated by cytokines; however, little is known about the cytokine profile in human SA. AIM: To determine the association of local and systemic cytokine profiles with the severity and prognosis of patients with SA. METHODS: Patients with clinical and laboratory diagnosed SA were enrolled as well as a control group. Serum and synovial fluid (SF) samples were obtained for determining cytokines and glucose levels; SF samples were used for histological analysis. Osteochondral damage and general health status and quality of life (SF-36) were evaluated during recruitment day. WOMAC osteoarthritis index score and SF-36 questionnaire were used a year after recruitment day as a follow up. RESULTS: A systemic and local proinflammatory cytokine profile was found in patients compared to the control group (p <0.05). IL-6 was 28 and 525 times higher than controls in sera and SF, respectively (p <0.0001). Systemic IL-6 correlated negatively with general mental health score (p = 0.0184) and was associated with a higher osteoarthritis index after one year follow-up in the patients (p = 0.0352). HMGB1 in SF was found higher in patients with SA (p <0.0001), and it was associated with osteochondral damage (p = 0.0042). TNF-α in SF correlated negatively with SF-36 questionnaire one year after patients' recruitment in role limitation score (p = 0.0318), body pain score (p = 0.0315), and general mental health score (p = 0.0197). CONCLUSION: Serum and SF cytokine signatures are associated with disease severity and prognosis in patients with SA.

Spinal epidural hematoma in antiphospholipid syndrome: case report and review of the literature.

INTRODUCTION: Spinal epidural hematomas are a surgical emergency, the delay in diagnosis can develop devastating sequelae due to its acute and progressive course. If not treated properly, it may lead to death or permanent neurological deficit. It is a rare condition that can occur in patients with hematologic pathology. CASE PRESENTATION: We report a case report and literature review of a patient with antiphospholipid syndrome, who undergoes a diagnostic lumbar puncture for probable fungal meningitis. Developed a spinal acute epidural hematoma with neurological involvement that is evidenced in MRI. Urgent surgical decompression was performed with good results. DISCUSSION: Despite the low incidence of an epidural hematoma in patients who undergo lumbar puncture, it is important to perform a thorough evaluation in any patient with coagulation abnormalities prior and after a lumbar puncture, by reason of the inherent possibility of developing an epidural hematoma at the site of the procedure. In the same way, early diagnosis and aggressive treatment is necessary in patients who develop progressive neurological symptoms to limit the damage and improve the prognosis for neurological recovery.
