Although rarely seen with newer TKA designs this was a diagnosis seen in patients with TKAs and could be extremely symptomatic.
Patellar clunk was first described by Hozack et al in 1989.
Patellar clunk occurred when a fibrous nodule forms above the patella. This nodule would get caught in the intercondylar notch in flexion and then cause a painful clunk as patients whet from flexion into extension.
This is a clinical diagnosis.
Patients tend to do well with arthroscopic debridement when there are no radiologic abnormalities such as loosening or malposistion.
