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...
