CrossFitter’s knee: patellofemoral chondral injury following high-intensity functional training.

We present a case series of patients with patellofemoral joint (PFJ) chondral injuries presenting as anterior knee pain secondary to participation in high-intensity functional training programmes. We aim to highlight PFJ chondral injuries as a potential complication of military servicemen engaging in high-intensity functional training programmes. This may allow medical staff to identify the injuries early, and highlight this possible injury mechanism to Physical Training staff to help educate participants and mitigate the risk of injury.
