If a dog with patellar luxation pops a kneecap out, what is the advised immediate action?

• A. Massage the joint
• B. Force the leg straight
• C. Ignore any signs of pain
• D. Place the kneecap back into position

Answer: (D)

Patellar luxation means the kneecap has slipped out of its normal groove, causing sudden pain and hind-leg instability. Placing the kneecap back into position is the best immediate action because realigning the joint relieves pain, restores function, and reduces further injury to the surrounding ligaments and cartilage. In practice, this should be done by a veterinarian or at least under professional guidance, as improper handling can cause additional damage. Avoid massaging, forcing the leg straight, or ignoring the pain, and seek urgent veterinary care to assess and treat the underlying instability.
