Deep Peroneal Nerve Articular Branch at Knee

ramus articularis nervi fibularis profundi ad genu

The deep peroneal nerve gives an articular branch to the anterolateral knee capsule as it passes lateral to the knee joint. This branch contributes to anterolateral capsular proprioception and pain signalling.

Region: Knee
Clinical Relevance

Clinical Notes

The deep peroneal articular knee branch is involved in anterolateral instability pain and anterolateral capsular syndromes. Its territory overlaps with the lateral superior genicular nerve territory already documented. In lateral ankle instability, the associated deep peroneal ankle branches produce proprioceptive deficits that contribute to recurrent sprain risk — analogous peroneal knee branches may contribute to anterolateral knee instability proprioceptive impairment.
