Background: Chronic Achilles tendon ruptures (CATRs) pose a clinical challenge because guidelines on optimal treatment modalities are lacking. This meta-analysis aims to investigate the use of Flexor Hallucis Longus (FHL) tendon transfer as a treatment option. Methods: A literature search was performed across multiple databases from inception until 31 July 2025. The databases searched included Ovid MEDLINE®, EMBASE (Elsevier), Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews. Included studies presented CATR patients of all ages, with no previous surgeries to the ankle, who were managed with an FHL tendon transfer (PROSPERO ID: CRD42023489724). Results: Sixteen studies met the eligibility criteria with 323 patients. For functionality, baseline AOFAS-AH (American Orthopaedic Foot & Ankle Society—Ankle Hindfoot) scores were 56.85 (95% CI: 51.03–62.68, I2 = 96%). At ≥12 months post-operative follow-up, AOFAS-AH scores were 91.46 (95% CI: 88.45, 94.48, I2 = 93%). ATRS (Achilles Tendon Rupture Score) at baseline was reported as 31.04 (95% CI: 5.80, 56.28, I2 = 99%). At ≥12 months post-operative follow-up, ATRS amounted to 90.73 (95% CI: 83.69, 97.77, I2 = 89%). Overall complication rates were 7.5% (CI: 0.04,0.11, I2 = 40%), consisting of superficial infections at 4.2% (95% CI: 0.01, 0.07, I2 = 0%), activity limitations at 4% (95% CI: 0.01, 0.08, I2 = 0%) and disturbed wound healing at 3.8% (95% CI: 0.01, 0.06, I2 = 0%). The minimum clinically important difference (MCID) for ATRS was achieved at 12 months onwards. Conclusions: Surgical management of CATR patients with FHL tendon transfer appears to improve functionality and subjective outcomes, supporting its use amongst the treatment modalities available.

Abstract Background Caesarean sections (CSs) constitute a large proportion of fetal deliveries, yet no consensus exists on optimal surgical method. Objectives To investigate the safety and efficacy of the Pfannenstiel‐Kerr method (PKM) in comparison to Misgav‐Ladach method (MLM) and Modified Misgav‐Ladach method (MMLM) for CS. Search Strategy Cochrane, Embase, PubMed, CiNAHL, Scopus, and Web of Science were searched from database inception to March 2023. Selection Criteria Prospective studies comparing MLM with PKM or MMLM with PKM. Data Collection and Analysis Three authors independently conducted data extraction and assessed quality. Pooled means and proportions were analyzed using inverse variance and Mantel‐Haenszel methods. Main Results Twenty‐seven studies with 15 251 patients, met the selection criteria. Both MLM (mean difference [MD]: −12.09 min, 95% confidence interval [CI]: −14.40, −9.77, Tau 2 = 16.79, I 2 = 97%), (MD: −125.98 mL, 95% CI: −172.13, −79.83, Tau 2 = 3458.59, I 2 = 87%) and MMLM (MD: −11.38 min, 95% CI: −14.72, −8.04, Tau 2 = 30.56, I 2 = 100%), (MD: −62.61 mL, 95% CI: −103.13, −22.09, Tau 2 = 1451.35, I 2 = 92%) demonstrated shorter operative time and decreased blood loss, respectively, compared to PKM. Similarly, both MLM (MD: −1.70 min, 95% CI: −2.26, −1.14, Tau 2 = 0.51, I 2 = 97%), (MD: −0.77 d, 95% CI: −1.35, −0.19, Tau 2 = 0.60, I 2 = 98%) and MMLM (MD: −2.80 min, 95% CI: −3.89, −1.70, Tau 2 = 1.74, I 2 = 100%), (MD: −0.58 d, 95% CI: −1.00, −0.17, Tau 2 = 0.29, I 2 = 100%) demonstrated shorter fetal extraction time and length of hospital stay, respectively, compared to PKM. Conclusions MLM and MMLM should be considered safe and effective alternative approaches to CSs.

AbstractThis meta‐analysis investigated the effects of exercise on Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) scores following vertebroplasty or kyphoplasty in osteoporotic fractures. A literature search of PubMed, EMBASE (Elsevier), CiNAHL, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Scopus, and Web of Science was conducted from database inception to October 6, 2022. Eligible studies reported osteoporosis patients over 18 years of age with a diagnosis of at least one vertebral fracture via radiography or clinical assessment. This review was registered in PROSPERO (ID: CRD42022340791). Ten studies met the eligibility criteria (n = 889). VAS scores at baseline were 7.75 (95% CI: 7.54, 7.97, I2 = 76.11%). Following initiation of exercise, VAS scores at the endpoint of 12 months were 1.91 (95% CI: 1.53, 2.29, I2 = 92.69%). ODI scores at baseline were 68.66 (95% CI: 56.19, 81.13, I2 = 85%). Following initiation of exercise, ODI scores at the endpoint of 12 months were 21.20 (95% CI: 14.52, 27.87, I2 = 99.30). A two‐arm analysis demonstrated improved VAS and ODI for the exercise group compared to non‐exercise control at 6 months (MD = −0.70, 95% CI: −1.08, −0.32, I2 = 87% and MD = −6.48, 95% CI: −7.52, −5.44, I2 = 46%, respectively) and 12 months (MD = −0.88, 95% CI: −1.27, −0.49, I2 = 85% and MD = −9.62, 95% CI: −13.24, −5.99, I2 = 93%). Refracture was the only adverse event reported and occurred almost twice as frequently in the non‐exercise group than in the exercise group. Exercise rehabilitation post vertebral augmentation is associated with improved pain and functionality, particularly after 6 months of exposure, and may reduce refracture rate.

AbstractPlatelet‐rich plasma (PRP) is an alternative to corticosteroid (CS) injections in managing rotator cuff disease. This meta‐analysis investigated differences between PRP and CS for function and pain scores in significance and minimal clinical important difference (MCID). A literature search of Ovid Cochrane Library, Medline, Embase, Epub, and Scopus was conducted from inception to October 28, 2021. Eligible studies reported patients older than 18 years with a diagnosis of rotator cuff disease. This review was registered in PROSPERO (ID: CRD42021278740). Twelve studies met eligibility criteria (n = 639) of patients receiving either PRP or CS. At short‐term follow‐up, a difference favored CS compared to PRP in baseline change for disability of arm, shoulder, and hand (DASH) score (MD = −5.08, 95% CI: −8.00, −2.15; p = 0.0007; I2 = 0%) and simple shoulder test (SST) (MD = 1.25, 95% CI: 0.33, 2.18; p = 0.008; I2 = 0%). At intermediate follow‐up, a difference favored PRP to CS baseline change of the DASH score (MD = 3.41, 95% CI: 0.67, 6.15; p = 0.01; I2 = 0%). At medium‐term, a difference favored PRP to CS baseline change of the American Shoulder and Elbow Surgeons Shoulder (ASES) score (MD = −4.42, 95% CI: −8.16, −0.67; p = 0.02; I2 = 0%). Both treatments achieved individual MCID for each score. Despite favoring CS at short‐term follow‐up and PRP at intermediate‐ and medium‐term follow‐up, functional and pain scores did not demonstrate any clinical difference between the two treatment modalities in management of rotator cuff disease at all follow‐up periods.
