What is cruciate ligament disease?

Cruciate ligament disease is the most common cause of hind-leg lameness in dogs. The cranial cruciate ligament (CCL) stabilises the knee joint, and when it ruptures or degenerates, the joint becomes unstable, painful, and prone to further damage. Unlike human ACL injuries, which are usually caused by a single trauma, most dogs develop cruciate disease gradually through progressive weakening of the ligament. Without treatment the knee deteriorates, leading to chronic pain and arthritis.

Symptoms to watch for

See a vet soon

Sudden or gradual lameness in one hind leg
Reluctance to bear weight on the affected leg
Stiffness after resting, especially noticeable on getting up
Swelling around the knee (stifle) joint
Clicking or popping sound from the knee when walking
Sitting with the affected leg out to the side
Muscle wasting in the affected thigh
Reduced willingness to exercise or play

How is cruciate ligament disease diagnosed?

Test	Typical cost
Consultation and orthopaedic examination	£35–£65
X-rays of the stifle joint (under sedation)	£150–£400
MRI scan (to assess meniscal damage before surgery)	£300–£600

Treatment options and costs

Conservative management (rest + medication)

£200–£500 initial, then £30–£80 per month ongoing

Strict rest for 6–8 weeks, anti-inflammatory medication, pain relief, weight management, and physiotherapy. May be suitable for dogs under 10 kg or those who are poor surgical candidates. Less predictable outcomes in larger dogs and does not address underlying joint instability.

Lateral suture stabilisation (extracapsular repair)

£1,500–£2,500

A strong nylon suture is placed outside the joint to stabilise the knee. More commonly used for small to medium dogs. Less expensive than TPLO but may be less durable in larger, more active dogs.

TPLO (tibial plateau levelling osteotomy)

£2,500–£4,000

The angle of the top of the tibia is surgically altered to remove the need for a cruciate ligament. Considered the gold-standard treatment for medium to large dogs. Performed by specialist orthopaedic surgeons and requires 8–12 weeks of restricted activity during recovery.

Does pet insurance cover cruciate ligament disease?

Cruciate ligament surgery is one of the most commonly claimed orthopaedic procedures in UK pet insurance. Most lifetime policies cover the full cost of diagnosis, surgery, and post-operative care, provided the condition develops after the policy start date. Some insurers impose a waiting period of 14–30 days for orthopaedic claims, and a few exclude cruciate disease specifically during the first 6–12 months. If one knee is already affected, insurers may exclude the other knee as a bilateral condition. Always check your policy wording carefully before proceeding with treatment.

Frequently asked questions

How much does cruciate ligament surgery cost in the UK?

TPLO surgery, the most common procedure for medium to large dogs, typically costs £2,500–£4,000 per knee including pre-operative imaging and post-operative care. Lateral suture repair is less expensive at £1,500–£2,500. Around 40–60% of dogs that rupture one cruciate will eventually rupture the other, so many owners face the cost twice.

Can a dog recover from a cruciate ligament injury without surgery?

Small dogs under 10 kg sometimes recover well with strict rest and medication, though there is usually some ongoing joint instability. Larger dogs generally have much poorer outcomes without surgery, with most developing significant arthritis. Conservative management is sometimes chosen for older dogs or those with other health problems that make surgery risky.

How long is the recovery from cruciate ligament surgery?

Most dogs need 8–12 weeks of strictly restricted activity after TPLO or lateral suture surgery. Lead walking only is typically allowed from 2–4 weeks, with a gradual return to normal exercise over 3–6 months. Physiotherapy and hydrotherapy can speed recovery and improve outcomes.

Is cruciate ligament disease the same as an ACL injury?

It is very similar. In humans, the equivalent ligament is called the anterior cruciate ligament (ACL); in dogs, it is called the cranial cruciate ligament (CCL). However, while human ACL injuries are usually caused by a sudden twist or impact, most dogs develop cruciate disease through gradual degeneration of the ligament over time.
