Joint Contact Forces in Chronic Ankle Instability (CIA)

It has long been postulated that arthritic progression in the ankle can relate to repetitive trauma, but there is limited empirical data linking joint contact forces with ligament instability. Using musculoskeletal modeling to estimate ankle joint contact forces (JCF), Jang and Wikstrom, help pull back the curtain in their article “Ankle joint contact force profiles differ between those with and without chronic ankle instability during walking.” 

CAI = High JCF

Patients with CAI had significantly different JCF forces, relative to uninjured controls, in all directions. Specifically, higher anteroposterior shearing forces were observed in individuals with CAI, along with higher mediolateral shearing forces. These findings provide support for the recommendation of surgical reconstruction in cases of chronic ankle instability. 

Mindshare at ACFAS 2024

Both Artelon and Biobrace displayed their advanced generation ligament augment materials at ACFAS this month. BioBrace is new to the game with a strip but no system. Artelon, with its well-developed platform and sizable market lead is the incumbent.
