Joint Replacement Arthroplasty

Joint Replacement Arthroplasty (Non-Hip) at MaxPetZ: Restoring Comfort and Mobility for Pets With Severe Joint Disease

When a joint becomes severely damaged from arthritis, injury, or developmental disease, it can cause constant pain and dramatically limit your pet’s quality of life. While many joint problems can be managed with medication, physical therapy, or corrective surgeries, some pets eventually reach a point where the joint can no longer function comfortably.
In these advanced cases, Joint Replacement Arthroplasty may be the best option.

Most pet owners are familiar with Total Hip Replacement (THR), but joint replacement is also possible in other areas, including the elbow, knee (stifle), and shoulder. These specialized procedures aim to restore your pet’s ability to walk, run, and enjoy daily activities again—free from chronic pain.

Why Non-Hip Joint Replacement May Be Recommended

Your veterinarian may discuss arthroplasty if your dog has:

• Severe arthritis that no longer responds to medication

• Elbow disease, especially medial compartment disease

• Joint collapse or deformity after injury

• Chronic pain affecting daily movement

• Failed previous joint surgeries

• Cartilage loss causing bone-on-bone contact

In many cases, arthroplasty offers a markedly better outcome than long-term medication or joint fusion (arthrodesis), particularly when maintaining joint motion is important.

Types of Non-Hip Arthroplasty Performed at MaxPetZ

1. Elbow Arthroplasty

The elbow is the joint most commonly replaced after the hip. Two main procedures are used:

CUE (Canine Unicompartmental Elbow Resurfacing)

Ideal for dogs with medial compartment disease.
Instead of replacing the entire elbow, only the damaged surfaces are resurfaced with smooth, durable implants. This relieves pain while preserving the rest of the joint.

Total Elbow Replacement (TER)

Used for end-stage elbow arthritis when the entire joint is affected.
TER replaces the humeral and ulnar surfaces to create a new, functional hinge joint.

2. Stifle (Knee) Arthroplasty

Although less common than hip or elbow replacement, it is recommended for:

• Severe arthritis not treatable with TPLO/TTA

• Chronic cartilage loss

• Advanced patellofemoral wear

Procedures may involve partial resurfacing or replacing specific joint surfaces to restore smoother movement.

3. Shoulder Arthroplasty

Used when the shoulder joint is irreversibly damaged by:

• Osteoarthritis

• Chronic instability

• Large cartilage defects

The glenoid (socket) or humeral head may be resurfaced or replaced, depending on the patient’s condition.

What to Expect After Surgery

Recovery is gradual and requires careful home management:

First 6–8 Weeks

• Strict rest

• Controlled, short leash walks

• No running or jumping

• Daily incision monitoring

• Continuous use of a recovery collar

Rehabilitation

Once the incision has healed, your pet may begin:

• Gentle strengthening exercises

• Underwater treadmill or swimming

• Gradual return to normal activity

Most pets show steady improvement and greater comfort within the first few months.

Long-Term Outlook

Many dogs experience significant pain relief, improved mobility, and a return to activities they previously avoided. While these procedures are highly specialized, MaxPetZ's advanced surgical systems and rehabilitation protocols help ensure the best possible outcome for your pet.

Owner-Facing FAQs: Joint Replacement Arthroplasty (Non-Hip)

1. How do I know if my dog needs joint replacement?

If your dog has ongoing pain, stiffness, limping, or difficulty using a limb despite medication and other treatments, arthroplasty may be recommended. Advanced imaging (X-rays or CT) confirms the diagnosis.

2. Is elbow replacement common?

It is less common than hip replacement, but elbow resurfacing (CUE) is increasingly used because it successfully treats medial compartment disease.

3. What is the difference between resurfacing and replacement?

• Resurfacing: Only the damaged areas are covered with implant components.

• Replacement: The entire joint surface is replaced.
  Your surgeon selects the option based on disease severity.

4. How long is the recovery period?

Most dogs need 8–12 weeks of controlled activity before returning to normal daily routines.

5. Will my dog walk normally again?

Many dogs experience major improvement in comfort and mobility. The degree of improvement depends on the joint involved and the severity of disease before surgery.

6. Are complications common?

Complications are possible, particularly with complicated joints like the elbow. These may include implant loosening, infection, or persistent lameness. However, careful aftercare significantly reduces risk.

7. Will the implant last my dog’s lifetime?

In most cases, yes—especially when weight control, activity guidelines, and follow-up visits are maintained.

8. How often will my dog need check-ups after surgery?

Follow-up X-rays are recommended at 6–10 weeks, 6 months, and then annually to monitor implant health.
