Biomechanical Impact and Failure Data with K-Wire Locations from a Rabbit Model of Cartilage Injury

<p>In vivo rabbit models that deliver mechanical impact to knee cartilage are important for studying injury-induced osteoarthritis, but variability in impact characteristics limits the repeatability of these models. This dataset contains impact and failure parameters derived from load cell and accelerometer output from a cadaveric rabbit posterior medial condyle impact model, along with k-wire placement locations for each specimen.</p>

<p>K-wire position was not prescribed and varied across specimens, and was treated as a source of variability in impact characteristics and subchondral bone failure outcomes. Impact parameters (peak stress, loading rate, impact duration, and work) and subchondral bone failure metrics are included, along with k-wire placement coordinates relative to the impact site in the sagittal plane.</p>

<p>These data were used to evaluate the relationship between k-wire placement and impact outcomes using multiple linear regression, and to assess the consistency of impact parameters when k-wire placement was reproduced with effort. These data may support future studies on cartilage injury mechanics, post-traumatic osteoarthritis disease progression, and the design and reproducibility of impact-based osteoarthritis animal models.</p>
