The rate of plagiarism and false content in scientific literature varies depending on the field of study and the methods used to detect it. According to some studies, the overall rate of plagiarism ...in scientific literature is estimated to be around 2-3% 1. However, the rate can be higher in certain fields and for certain types of content. Additionally, the rate of false or fraudulent content in scientific literature is difficult to quantify, as it often goes undetected or is not reported. However, cases of scientific misconduct, including the fabrication and falsification of data, have been reported in various fields and can have serious consequences for both the authors and the scientific community. It is important for the scientific community to maintain high standards of ethics and accuracy in scientific research to ensure the validity and reliability of the published literature. In this editorial, we will touch upon the description of Large Language Models, define their limits and strengths and finally explore options to detect fraudulent manuscripts. Large Language Models (LLM) have the potential to assist researchers in generating clear and concise writing, summarising vast amounts of information and performing various language-related tasks 2.

Purpose
Weight‐bearing computed tomography (WBCT) enables the creation of a three‐dimensional (3D) model that represents the ankle morphology in a standing position. Distance mapping (DM) is a ...complementary feature that uses color coding to represent the relative intraarticular distance and can be used to outline intraarticular defects. Consequently, DM offers a novel approach to delineating osteochondral lesions of the talus (OLT), allowing for the quantification of its surface, volume and depth. The reliability of DM for OLT measurements has yet to be thoroughly evaluated. This study primarily aims to determine the reliability of DM in measuring the surface, depth and volume of OLT. A secondary objective is to ascertain whether measurements obtained through DM, when integrated with a predefined treatment algorithm, can facilitate consensus among surgeons regarding the optimal surgical intervention.
Methods
This cohort comprised 36 patients with 40 OLTs evaluated using WBCT and DM. Two raters used DM to determine the lesion boundary (LB) and lesion fundus (LF) and calculate the lesion depth, surface and volume. The raters were asked to choose between bone marrow stimulation, autologous matrix‐induced chondrogenesis and osteochondral transposition based on the measurement. Inter‐rater and intra‐rater agreement was measured.
Results
Interclass correlation of the lesion's depth surface produced an excellent inter‐rater and intra‐rater agreement of 0.90–0.94 p < 0.001. Cohen's κ agreement analysis of the preferable preoperative plan produced a κ = 0.834, p < 0.001, indicating a near‐perfect agreement.
Conclusion
WBCT‐based 3D modules and DM can be used to measure the lesion's surface, depth and volume with excellent inter‐rater and inter‐rater agreement; using this measurement and a predetermined treatment algorithm, a near‐perfect inter‐rater agreement for the preoperative planning was reached. WBCT in conjunction with AI capabilities could help determine the type of surgery needed preoperatively, evaluate the hindfoot alignment and assess if additional surgeries are needed.

To assess the patient-reported outcomes, as well as the revision and complication rates, of patients who underwent arthroscopic bone marrow stimulation (BMS) for an osteochondral lesion of the tibial ...plafond (OLTP).
Patients with an OLTP treated with arthroscopic BMS at a minimum follow-up of 2-years were cross-sectionally included from a historical database. The primary outcome was the Numeric Rating Scale (NRS) during walking. Secondary outcomes included the NRS in rest and during running, and the Foot and Ankle Outcome Score. Additionally, the association of baseline patient and lesion demographics with follow-up patient-reported outcome measures (PROMs) was assessed with the Spearman rank correlation test. A subanalysis was performed for PROMs in patients with or without a coexisting talar (i.e., bipolar) lesion. Finally, the revision surgery (i.e., repeat surgery for the OLTP) and complication rates were assessed.
Fifty-one patients were included at a mean 8.8 (standard deviation SD = 5.7, range, 2-22) years follow-up. Seventy-three percent of patients had a solitary OLTP, and 27% had a coexisting talar (bipolar) lesion. Males had a significantly higher rate of bipolar lesions compared to females (P ≤ .01), and patients with a bipolar lesion had a significantly larger OLTP lesion diameter (P = .02) and volume (P = .04). At final follow-up, the mean NRS during walking was 1.9 (SD = 2.3) out of 10. Anterior-posterior OLTP size (r = 0.36; P ≤ .01) was significantly associated with a higher NRS pain score during walking, although the presence of bipolar lesions did not result in inferior clinical outcomes. At final follow-up, 6% of patients underwent revision surgery. Minor complications were observed in 12% of patients.
Arthroscopic BMS for OLTP results in favorable patient-reported outcomes at mid- to long-term follow-up, although moderate outcomes were observed in sports activities. Lesion size was associated with increased pain scores, although bipolar lesions did not result in inferior patient-reported outcomes. Six percent of patients required revision surgery, and 12% of patients had minor complications after surgery.

Purpose
The purpose of this systematic literature review is to detect the most effective treatment option for primary talar osteochondral defects in adults.
Methods
A literature search was performed ...to identify studies published from January 1996 to February 2017 using PubMed (MEDLINE), EMBASE, CDSR, DARE, and CENTRAL. Two authors separately and independently screened the search results and conducted the quality assessment using the Newcastle–Ottawa Scale. Subsequently, success rates per separate study were calculated. Studies methodologically eligible for a simplified pooling method were combined.
Results
Fifty-two studies with 1236 primary talar osteochondral defects were included of which forty-one studies were retrospective and eleven prospective. Two randomised controlled trials (RCTs) were identified. Heterogeneity concerning methodological nature was observed, and there was variety in reported success rates. A simplified pooling method performed for eleven retrospective case series including 317 ankles in the bone marrow stimulation group yielded a success rate of 82% CI 78–86%. For seven retrospective case series investigating an osteochondral autograft transfer system or an osteoperiosteal cylinder graft insertion with in total 78 included ankles the pooled success rate was calculated to be 77% CI 66–85%.
Conclusions
For primary talar osteochondral defects, none of the treatment options showed any superiority over others.

Purpose
The aim of this study was to assess the return to amateur sports of patients under 65 years, following medial unicompartmental knee arthroplasty (mUKA) versus lateral unicompartmental knee ...arthroplasty (lUKA). It was hypothesized that patients younger than 65 years who underwent lateral or medial unicondylar knee replacement will result in similar rates to amateur sports, at a minimum follow-up of 2 years.
Method
Patients who underwent medial or lateral UKA participated in a 2-year follow-up program, where they were clinically evaluated for their return to amateur sports, using the University of California, Los Angeles (UCLA) activity scale and the High-Activity Arthroplasty Score (HAAS). Furthermore, subgroup analyses by gender and age were performed. Power analysis was performed to ensure sample size considering that lUKA is implanted ten times less frequently than its medial counterpart.
Results
There were 85 patients who completed the entire minimum 2-year follow-up of which 73 belonged to the mUKA group and 12 to the lUKA group. No preoperative differences were found between the groups regarding the gender, the affected side, age, and mean follow-up. Both groups showed statistically significant improvement (
p
< 0.05) in their return to amateur sports in all parameters (UCLA and HAAS). No differences among the two groups were found at

All subgroups showed a statistically significant improvement (
p
< 0.05) with respect to the preoperative value, except for UCLA for lUKA with less than 60 years and HAAS for males in the lUKA group (n.s.). No differences were found among subgroups both at

(n.s.).
Conclusion
Both mUKA and lUKA procedures enabled all young and active patients a certain return to amateur sports 2 years after surgery, regardless of age and gender. UKA, medial or lateral, should always be considered for the treatment of isolated osteoarthritis in young and active patients with high functional demands.

A meta-analysis is the quantitative synthesis of data from two or more individual studies and are as a rule an important method of obtaining a more accurate estimate of the direction and magnitude of ...a treatment effect. However, it is imperative that the meta-analysis be performed with proper, rigorous methodology to ensure validity of the results and their interpretation. In this article the authors will review the most important questions researchers should consider when planning a meta-analysis to ensure proper indications and methodologies, minimize the risk of bias, and avoid misleading conclusions.
