Comparison of optical coherence tomography and histopathology in quantitative assessment of goat talus articular cartilage

Background and purpose — Optical coherence tomography (OCT) is a light-based imaging technique suitable for depiction of thin tissue layers such as articular cartilage. Quantification of results and direct comparison with a reference standard is needed to confirm the role of OCT in cartilage evaluation. Materials and methods — Goat talus...

Feasibility study to determine if microfracture surgery using water jet drilling is potentially safe for Talar chondral defects in a Caprine model

Objective: Surgical microfracture is considered a first-line treatment for talar osteochondral defects. However, current rigid awls and drills limit access to all locations in human joints and increase risk of heat necrosis of bone. Using a flexible water jet instrument to drill holes can improve the reachability of the defect without...
