[6] [4] Surgery may be indicated in those cases where a fracture occurs within the joint or where the patella has repeatedly dislocated.

[4] Rates in males and females are ...

Even with luxating patella, symptoms such as intermittent limping in the rear leg might be mild or absent. Physical examination and manual manipulation are the preferred methods for diagnosis.

[5] [8] [9] Some surgeons however would rather opt for internal ...
