Cruciate rupture in small dogs: conservative management?
9-year-old Maltese, 7 kg (ideal 6 kg), with a 10-day right hind limb lameness and positive cranial drawer. No meniscal click is felt. The owners would prefer to avoid surgery if possible.
Which statement is correct?
chevron_right Show answer and explanation
A. It is a reasonable option: weight loss, controlled lead exercise, NSAIDs and physiotherapy, monitoring progress; if there is no improvement or a meniscal injury appears, surgery is reconsidered
Correct. Many dogs under 15 kg regain acceptable function with conservative management, although surgery usually gives a faster and more complete recovery. Osteoarthritis progresses either way.
B. Surgery is contraindicated in dogs under 10 kg
It is not: lateral fabellotibial suture or TPLO give good results in small dogs and are the preferred option if conservative management fails.
C. It must be kept caged, without walks, for 6 months
Prolonged strict rest promotes muscle atrophy and stiffness. Controlled, short and frequent lead exercise, increased progressively, is what is indicated.
D. Glucosamine and chondroitin alone are sufficient
Chondroprotectants have little evidence of efficacy and do not replace weight control, controlled exercise and analgesia.
lightbulb Key takeaway
In small dogs conservative management is valid if owners prefer it, but it is not 'doing nothing': ideal weight, controlled exercise, analgesia and physiotherapy. A click or sudden deterioration during treatment suggests meniscal injury and usually requires surgery.
