Unlabelled: Osteogenesis imperfecta (OI) is a hereditary skeletal dysplasia with an incidence of approximately 1:15,000 to 20,000. OI is usually caused by the mutation of COL1A1 and COL1A2, which would encode the α-chain of type I collagen. OI is clinically characterized by decreased bone mass, increased risk of bone fragility, blue sclerae, and dentinogenesis.
Case Presentation: A 29-year-old male patient was diagnosed with right tibial plateau fracture caused by slight violence. Physical examination revealed the following: height, 140 cm; weight, 70 kg; body mass index (BMI), 35.71 kg/m; blue sclera and barrel chest were observed. X-ray examination showed left convex deformity of the thoracic vertebrae with reduced thoracic volume. Laboratory examinations revealed a decrease in both vitamin D and blood calcium levels. Bone mineral density (BMD) was lower than the normal range. After the preoperative preparation was completed, the open reduction and internal fixation of the right tibial plateau fracture were performed. Meanwhile, whole blood samples of this OI patient and the normal control were collected for RNA transcriptome sequencing. The RNA sequence analysis revealed that there were 513 differentially expressed genes (DEGs) between this OI patient and the normal control. KEGG-enriched signaling pathways were significantly enriched in extracellular matrix (ECM)-receptor interactions.
Conclusion: In this case, DEGs between this OI patient and the normal control were identified by RNA transcriptome sequencing. Moreover, the possible pathogenesis of OI was also explored, which may provide new evidence for the treatment of OI.

Correlation of Increased Lateral Tibial Slope With Baseline Tibial Position in Intact Knees and Side-to-Side Anterior Tibial Translation for Knees With ACL Tears.
Am J Sports Med
January 2025
Twin Cities Orthopedics, Edina, Minnesota, USA.
Background: Anterior cruciate ligament (ACL) stress techniques-including single-leg stress radiographs, Telos, and KT-1000 arthrometer-are highly accessible and can provide additional diagnostic information to assess ACL and ACL graft integrity. The degree of anterior tibial translation (ATT) may be useful in guiding treatment when a diagnosis on magnetic resonance imaging is not conclusive or for judging if additional treatments, such as anterolateral complex augmentation, may be necessary.
Purpose/hypothesis: The purpose of this study was to evaluate the effect of increasing posterior tibial slope (PTS) on baseline tibial position (BTP) and side-to-side differences (SSD) in ATT.
Effect of ELHLD peptide for stifle function recovery after tibial plateau leveling osteotomy in dogs.

Importance: Patients with arthritis and ruptured cruciate ligaments typically require surgery. Following surgery, it is necessary to improve joint function in early stage.
Objective: This study aimed to investigate the impact of intraoperative intra-articular injection of the ELHLD peptide (L-glutamyl-L-leucyl-L-histidyl-L-leucyl-L-aspartic acid) on postoperative stifle function in patients with medial patella luxation grade 3 and osteoarthritis grade 2 undergoing tibial plateau leveling osteotomy due to anterior cruciate ligament (ACL) rupture.
Medial Meniscus Ramp Tears: State of the Art.
J ISAKOS
December 2024
Twin Cities Orthopedics, Edina, Minnesota, USA. Electronic address:
Medial meniscus ramp tears are tears of the posteromedial capsule or peripheral rim of the posteromedial meniscus that frequently occur with anterior cruciate ligament (ACL) tears. The incidence and prevalence of medial meniscus ramp tears has been increasing in the recent literature due to the increased understanding of the anatomy and diagnosis of these tears. When a patient presents with an ACL tear, a medial meniscus ramp tear should be suspected if the patient has a grade 3+ Lachman or pivot shift exam, a vertical line of increased signal intensity in the posterior capsule or peripheral meniscus on magnetic resonance imagining (MRI), or posteromedial tibial plateau bone bruising on MRI.

Department of Companion Animal Clinical Studies, Faculty of Veterinary Science, University of Pretoria, Onderstepoort, Pretoria, South Africa.
Objective: The aim was to investigate the patellar ligament strain with varying degrees of tibial plateau angles (TPAs) after tibial plateau leveling osteotomy (TPLO) in a cranial cruciate ligament (CrCL)-deficient stifle during the stance phase.
Methods: 12 pelvic cadaver limbs were secured to a custom-built jig to mimic a loadbearing stance after which an axial load of 120 N was applied. Patellar ligament strain, change in strain, and percent change in strain were calculated on pre-TPLO (intact and transected CrCL) and post-TPLO tibial TPAs of -5°, 0°, 5°, 10°, and 15°.
Advanced Trauma Care With Tricalcium Phosphate Bone Grafts for Tibial Plateau Fractures: A Report of Three Cases.

Article Synopsis
- Advances in implants and biological therapies have improved trauma care, especially for complex cases like Schatzker type V tibial plateau fractures.
- This study evaluates three patients treated with open reduction and internal fixation plus tricalcium phosphate bone void filler, assessing outcomes through various scoring systems.
- Results showed high patient satisfaction and low pain levels, with good range of motion and no significant complications, indicating that tricalcium phosphate may enhance recovery by supporting healing and integration.
