  • Composite metric R2 − R1ρ (1/T2 − 1/T1ρ) as a potential MR imaging biomarker associated with changes in pain after ACL reconstruction: A six-month follow-up

    Composite metric R2 − R1ρ (1/T2 − 1/T1ρ) as a potential MR imaging biomarker associated with changes in pain after ACL reconstruction: A six‐month follow‐up

    Average cross-sectional R2 − R1ρ SPMs of all patients overlaid onto registered image (A, B, D, and E) with the corresponding average percent difference maps (C and F) in the patella and trochlea. Lower relaxation rate differences indicate more similar R1ρ and R2 values.

  • Fractures of the tibial plateau involve similar energies as the tibial pilon but greater articular surface involvement

    Fractures of the tibial plateau involve similar energies as the tibial pilon but greater articular surface involvement

    Custom-written software was used to measure surface area of pre-injury cortical and subchondral bone surfaces and post-injury-exposed interfragmentary bone surfaces. The fracture-liberated surface area and the bone densities across that surface were used to calculate fracture energy. The length of the edge between the subchondral and interfragmentary bone surfaces (the articular fracture edge length—highlighted with dashed black lines) was used to quantify articular surface involvement.

  • Clinical platform for understanding the relationship between joint contact mechanics and articular cartilage changes after meniscal surgery

    Clinical platform for understanding the relationship between joint contact mechanics and articular cartilage changes after meniscal surgery

    Results of cartilage qMRI values and thickness before and after the surgery of a representative subject (subject 4). (A) T1ρ map of the tibial cartilage in the superficial layer and deep layer. Decreased T1ρ values were seen in the cartilage-meniscus (CM) region, especially in the superficial layer. (B) Prolonged T2 values were found within the CC zone of the deep layer. (C) No significant changes were found in cartilage thickness in both CC and CM zones.

  • Binding and lubrication of biomimetic boundary lubricants on articular cartilage

    Binding and lubrication of biomimetic boundary lubricants on articular cartilage

    (a–c) Fluorescence confocal microscopy shows binding of fluoroscein-tagged lubricin mimetics to cartilage surfaces. (d–f) The surface of cartilage was located using the natural reflectance of the collagen fibers of cartilage. The reflactance images remains at a relatively constant intensity. The fluorescent images above show an increase in fluorescent intensity as incubation time increases, indicating an increase in lubricant binding. Additionally, distinct fibers (F) have a relatively higher fluorescent intensity showing that the polymers have a specific affinity for collagen fibers.

  • Complementary models reveal cellular responses to contact stresses that contribute to post-traumatic osteoarthritis

    Complementary models reveal cellular responses to contact stresses that contribute to post‐traumatic osteoarthritis

    MRI images of goat knee before and 6 months after impaction and partial meniscectomy.

  • Global molecular changes in a tibial compression induced ACL rupture model of post-traumatic osteoarthritis

    Global molecular changes in a tibial compression induced ACL rupture model of post‐traumatic osteoarthritis

    Enriched phenotypes associated with genes up-regulated at 1 day (D1), 1- (W1), 6- (W6), and 12 weeks (W12) post injury. Up-regulated genes associated with Arthritis phenotypes are highlighted at the bottom, left side.

  • Post-traumatic osteoarthritis of the ankle: A distinct clinical entity requiring new research approaches

    Post‐traumatic osteoarthritis of the ankle: A distinct clinical entity requiring new research approaches

    Comparative talus anatomy. Size comparison of left tali from species commonly used as animal models in osteoarthritis research; (A) horse, (B) pig, (C) sheep, (D) dog, (E) rat, (F) mouse, compared to the (G) human.
