patellar luxation: what you should know about this knee problem in chihuahuas

famous chihuahua editor chihuahua facts, chihuahua health concerns 31 Comments

the chihuahua breed is known to have the knee condition known as patellar luxation and is one of the most common health problems associated with chihuahuas.   the knee is a complex structure consisting of muscles, ligaments, tendons, cartilage, and bones.   these components must align properly and interact harmoniously in order to function properly.  three bones are included in the knee: the femur, the tibia, and the patella (kneecap).

the lower front portion of the femur (thigh bone) in a normal chihuahua has two bony ridges that form a fairly deep groove in which the patella is supposed to slide up and down.  these structures limit the patella’s movement to one restricted place, and in doing so, control the activity of the quadriceps muscle.  the entire system is constantly lubricated by joint fluid.  it works so that there is total freedom of motion between the structures.

    ,my chi has had both knees done on 6 th march . It’s been 24 days now , I still restrict him from jumping and running , although he really looks fine now , I have kept him in a cage since surgery only letting him out for a wee on a lead , and for cuddles on the settee with me . He settled well in the cage and doesn’t mind it , but now he is feeling better he wants to play , only a couple more weeks and he will be free ! Bless him

    Thanks for the video, good to know what this looks like! Rarely, on walks, Matilda will randomly start limping for a few steps, then appear to get better, no whining or yelping. I was wondering if she was starting to develop luxating patella in one of her legs, we’ll continue our regular walks and hope it doesn’t worsen.

    One of my chi’s has this problem in both rear legs-doesnt seem to slow him down-hes slim & very active-but it really does look weird when he stands up on his back legs…very bowed

    my friend has a female 4 year old chi, that is way over weight 12 -14 pounds,she has luxating patella in one rear leg,vet says she needs surgery,okay but if she lost weight and took glucosaime would that help the problem with out surgery? also they say she has a liver problem so they feed her cooked chicken,could liver problem be caused by being over weight?
