Objective: To compare the posterior cruciate ligament(PCL) index with six different measurement methods, and analyze and verify its clinical diagnostic value in anterior cruciate ligament (ACL) injury.
Methods: The Magnetic resonance imaging (MRI) data of 225 knee joints in our hospital from May 2018 to March 2022 were retrospectively analyzed, aged from 18 to 60 years old, with a median of 32 years old. On the sagittal MRI images of 114 patients with ACL injury and 111 patients with intact ACL, Measure the straight-line distance (A) between the femoral attachment point and the tibial attachment point of the PCL on the MRI sagittal image and the maximum vertical distance (B) between the straight line and the arcuate mark point of the PCL on the sagittal image, calculate the PCL index and evaluate the diagnostic value of the PCL index for ACL injury.
Results: The PCL index of the ACL normal group and the ACL injury group were statistically described. There was no significant difference in PCL index 1, 2, 3 and 6 between the two groups(>0.05). The difference of PCL index 4 and 5 between the two groups was statistically significant (<0.001). This study only found that the PCL index 2, 6 in the ACL normal group had a negative correlation with the patient's age (correlation coefficient=-0.213, -0.819;<0.05), and the PCL index 5 in the ACL injury group was significantly correlated with the patient's body mass index(BMI)had a negative correlation (correlation coefficient=-0.277, <0.05).
Conclusion: The change of PCL index is helpful for the diagnosis of ACL injury, PCL index 4 and 5 can be used as effective reference indexes for diagnosing ACL injury in clinic.

Sports Medicine Institution of Orthopaedics, The First Affiliated Hospital of Air Force Military Medical University, Xi'an, 710000, China.
Background: This study aimed to describe the arthroscopic superlateral capsule pathway technique for spotting femoral fixation device deployment, and to compare the results with normal procedure.
Methods: A total of 69 patients underwent ACLR (Anterior Cruciate Ligament Reconstruction) with or without the SCP (superolateral capsule pathway) during procedure were retrospectively selected and evaluated. A total of 36 patients underwent SCP and 33 patients underwent ACLR without SCP.
Inverted supracondylar femoral dynamic compression plates for revision of construct failure following tibial cranial closing wedge ostectomy in three dogs.

Construct failure is a rare complication of tibial cranial closing wedge ostectomy for the management of cranial cruciate ligament disease. Construct failure can present significant challenges for reconstruction. This case report describes three dogs with construct failure which were successfully revised by the repurposing of an inverted femoral supracondylar femoral plate as part of the revision.

Purpose: To evaluate the healing of meniscal repair performed concomitantly with anterior cruciate ligament reconstruction (ACLR) using second-look arthroscopy, and the relationship between meniscal healing and knee laxity using quantitative evaluation under anesthesia.
Methods: This retrospective study included patients who underwent primary double-bundle ACLR with meniscal repair between June 2016 and June 2021, with a two-year minimum follow-up. Meniscal healing was evaluated by second-look arthroscopy at least one year postoperatively, and knee laxity was measured under general anesthesia preoperatively, intraoperatively, and at second-look.

Department of Orthopaedic Surgery, Chonnam National University Hwasun Hospital, College of Medicine, Chonnam National University, 322, Seoyang-ro, Hwasun, 58128, Republic of Korea. Electronic address:
Purpose: To compare graft remodeling, as measured by magnetic resonance imaging (MRI), and clinical outcomes between patients who underwent isolated anterior cruciate ligament reconstruction (ACLR) versus combined anterior cruciate ligament and anterolateral ligament reconstruction (ACLR + ALLR).
Methods: A retrospective review was conducted on patients who underwent primary ACLR with quadruple hamstring grafts between January 2019 and March 2022, with a minimum follow-up period of 2 years. Patients were categorized into two groups based on the addition of ALLR with tibialis anterior allografts: an isolated ACLR group and an ACLR + ALLR group.
High specificity of an AI-powered framework in cross-checking male professional football anterior cruciate ligament tear reports in public databases.

Department of Orthopaedic Surgery, Centre Hospitalier de Luxembourg - Clinique d'Eich, Luxembourg, Luxembourg.
Purpose: While public databases like Transfermarkt provide valuable data for assessing the impact of anterior cruciate ligament (ACL) injuries in professional footballers, they require robust verification methods due to accuracy concerns. We hypothesised that an artificial intelligence (AI)-powered framework could cross-check ACL tear-related information from large publicly available data sets with high specificity.
Methods: The AI-powered framework uses Google Programmable Search Engine to search a curated, multilingual list of websites and OpenAI's GPT to translate search queries, appraise search results and analyse injury-related information in search result items (SRIs).
