Video Summary

In this video, Mark Farndon, a specialist orthopaedic lower limb surgeon from the UK, discusses a method developed by him and colleagues from Leeds University to assess the tribological effects of osteochondral defects in the ankle joint. Osteoarthritis and its treatments, and the stability of repairs with respect to frictional properties within the joint, are discussed. The tribological simulation of the tibiotalar joint involved using cadaveric specimens and assessing the diameter and center of rotation. The study found that the introduction of a chondral defect and subsequent repair can affect frictional changes within the joint. The methodology provides a platform to assess the stability of different chondral repairs in the tibia-talar joint. The main limitation is the absence of the fibula and ligamentous tissue in the model. No credits were mentioned in the video.
