Luxating Patella in Maltese Dogs: Prevention & Mobility Tips
Maltese are a classic toy breed: long-lived (12–15 years), intentionally bred for small size, and beloved for their white coats and bright personalities. By 8–9 years a Maltese is considered a senior, and age-related orthopedic problems — including luxating patella — commonly affect mobility and [quality of life](https://seniorpet.org/knowledge/siamese-cat-quality-of-life "Quality of Life Assessment"). This article focuses on breed-specific information about luxating patella in senior Maltese, how the condition interacts with common Maltese health issues (mitral valve disease, [dental disease](https://seniorpet.org/knowledge/siamese-cat-dental-disease "Dental Disease in Senior Pets"), collapsed trachea, portosystemic shunt, cataracts, and white shaker syndrome), and practical, actionable steps owners can take to prevent progression and preserve mobility.
Why Maltese are at risk
Maltese are one of the small/toy breeds with a higher predisposition to medial patellar luxation (MPL). The condition often has a congenital or developmental component — shallow femoral trochlea, femoral or tibial malalignment, or abnormally positioned quadriceps mechanism — which can be subtle early in life but become clinically important in middle-to-late age as joint wear, body weight changes, and other comorbidities accumulate.
Common breed comorbidities that influence diagnosis, treatment choices, and anesthesia safety in senior Maltese:
- [Mitral valve disease](https://seniorpet.org/knowledge/cavalier-king-charles-spaniel-mitral-valve-disease "Mitral Valve Disease Guide") (MVD): high prevalence in small breeds; heart murmur and reduced cardiac reserve increase anesthesia risk and influence surgical planning.
- Dental disease: very common in Maltese; untreated periodontal disease increases risk of bacteremia and can complicate anesthesia recovery.
- Collapsed trachea: chronic cough and airway reactivity can complicate sedation and endotracheal intubation.
- Portosystemic liver shunt (PSS): affects drug metabolism (less common to be first discovered in seniors but possible) and alters anesthetic drug choices and dosing.
- Cataracts and visual impairment: can worsen fall risk and mobility adaptation.
- White shaker syndrome: a steroid-responsive tremor syndrome seen in small white breeds (including Maltese), which can mimic or worsen perceived mobility deficits.
What is a luxating patella?
The patella (kneecap) tracks in the femoral trochlea. Luxation means the patella intermittently or persistently dislocates (usually medially in Maltese). Clinical signs can include intermittent skipping/“skate” lameness, holding the leg up, stiffness after rest, progressive hind limb lameness, and decreased activity.
Grading of patellar luxation
The standard veterinary grading system (I–IV) guides treatment decisions. The table below summarizes the grades with typical presentation and usual treatment approach.| Grade | Physical findings (what the vet sees) | Typical clinical signs | Common treatment approach | |---:|---|---|---| | I | Patella can be manually luxated but returns to normal position; stable trochlea | Often no lameness; intermittent “skipping” | Conservative: weight management, exercise modification, monitoring | | II | Patella luxates frequently with stifle flexion; may reduce spontaneously | Intermittent lameness, skipping, mild to moderate discomfort | Conservative trial; surgical correction if recurrent/painful | | III | Patella luxated most of the time but can be manually reduced | Persistent lameness, muscle atrophy | Surgical correction usually recommended | | IV | Patella permanently luxated; trochlear groove often shallow/absent | Severe lameness, deformity, OA | Surgical correction required; may need complex reconstruction |

Diagnosis in the senior Maltese
A careful, breed-aware diagnostic workup should include:
- Thorough orthopedic exam (gait analysis, stifle palpation, range-of-motion).
- Stifle radiographs (extended and flexed views) to evaluate trochlear depth, conformation, and concurrent osteoarthritis.
- Orthopedic surgeon consult for planning if surgical correction is considered.
- Pre-anesthetic screening that is especially important in senior Maltese:
Because Maltese commonly have MVD and airway or dental issues, coordination among your general veterinarian, a board-certified surgeon (or experienced practitioner), and possibly a cardiologist or internist improves safety and outcomes.
Treatment options: conservative vs surgical
Treatment choice depends on grade of luxation, pain and lameness severity, presence of osteoarthritis, and the dog’s overall health status.
Conservative management (appropriate for many Grade I–II seniors, and some Grade III with comorbidities)
- Weight management: maintain an ideal body condition score (BCS 4–5/9). Extra weight increases patellofemoral stresses even on small bodies like a Maltese’s.
- Low-impact exercise: short, controlled leash walks and gentle play maintain muscle mass without high-impact forces. Avoid repetitive jumping from furniture.
- Physical rehabilitation and home exercises: quadriceps strengthening, controlled sit-to-stand exercises, and active range-of-motion help stabilize the stifle.
- Hydrotherapy (under professional supervision): underwater treadmill is highly effective for low-impact strengthening and conditioning; several studies support improved function in dogs with orthopedic disease when combined with a structured program.
- Joint supplements: veterinary formulations that include omega-3 fatty acids (EPA/DHA), glucosamine, chondroitin, and green-lipped mussel may provide symptom relief. Use products with quality control (veterinary brands) and follow veterinary dosing.
- Pain control/anti-inflammatory therapy: when indicated, use veterinarian-prescribed NSAIDs (after bloodwork and discussing concurrent MVD or liver disease), or other analgesics like gabapentin. Avoid over-the-counter human NSAIDs.
- Bracing/orthotics: custom braces may help some dogs by limiting luxation events and providing proprioceptive support; evidence is variable and braces must be fitted by professionals experienced with small breeds.
- Environmental modifications: non-slip flooring, ramps for furniture access, raised food bowls to reduce stooping, and removal of slippery surfaces.
Surgical correction (recommended for many persistent Grade II–IV cases)
Surgery aims to realign the extensor mechanism and deepen the trochlear groove. Typical procedures include:- Trochleoplasty (widening/deepening the trochlear groove).
- Tibial tuberosity transposition (realigns the pull of the patellar tendon).
- Medial/lateral soft tissue releases or imbrication (tightening or releasing retinacular structures).
- Corrective osteotomies for severe tibial/femoral deformities when present.
Anesthesia and comorbidity considerations specific to Maltese
Senior Maltese frequently present with one or more of the comorbidities listed earlier. These conditions influence anesthetic choice, perioperative monitoring, and post-op care.
- Mitral valve disease (MVD): pre-anesthetic echocardiography or cardiology consult is recommended if a murmur is present. Anesthetics that maintain hemodynamic stability are preferred; perioperative fluid management should be cautious to avoid volume overload.
- Collapsed trachea: airway management may be difficult; consider sedation protocols that minimize airway irritability, use smaller endotracheal tubes, and have bronchodilators and appropriate monitoring ready.
- Portosystemic shunt: impaired drug metabolism may require dose adjustments, avoidance of certain drugs, and perioperative hepatic-protective strategies. Pre-op bloodwork is essential.
- Dental disease: treat active infections before elective surgery when possible; dental disease increases anesthetic and postoperative infection risk.
- White shaker syndrome: corticosteroid therapy is the standard of care; if a dog is being treated with steroids, discuss with your vet before surgery — steroids influence wound healing and interact with NSAIDs and other drugs. Conversely, tremors from white shaker syndrome can reduce measurable improvement in mobility if not controlled.
Rehabilitation and long-term mobility strategies
Postoperative rehabilitation or conservative therapy programs are key to good outcomes. Tailor rehabilitation to the senior Maltese’s size, temperament, and comorbidities.
Practical, actionable rehab measures:
- Start with short sessions (5–10 minutes) multiple times per day; increase according to tolerance.
- Controlled strength exercises: sit-to-stand repetitions, supported standing on an incline, slow stair climbs (one step at a time) when appropriate.
- Range-of-motion stretching: gentle passive flexion and extension of the stifle several times daily — stop if painful.
- Hydrotherapy: 10–20 minute sessions 2–3 times weekly can build muscle without high joint loading. Ensure water temp is warm and sessions are supervised by a canine rehab professional.
- Use balance/proprioceptive tools: wobble boards or low cushions can help a Maltese regain proprioception after luxation events — always supervised and starting at a low difficulty.
- Monitor muscle mass: a small dog loses muscle quickly; progressive strengthening prevents rapid decline.
- Consistent pain management: even low-grade pain reduces activity and leads to deconditioning; maintain scheduled analgesics as directed.
Home modifications and daily care for senior Maltese
- Eliminate slippery surfaces. Use rugs or shelf-liner on laminate and tile floors.
- Provide low-profile ramps for furniture or car access; teach the dog to use them.
- Keep bedding low and supportive; orthopedic beds with a small step for entry are ideal for seniors.
- Place food/water bowls at a comfortable height to avoid excessive hip/stifle flexion if [arthritis](https://seniorpet.org/knowledge/golden-retriever-arthritis-pain-management "Arthritis Management in Senior Pets") is present.
- Maintain a consistent, short-leash walking routine; avoid off-leash running on uneven ground.
- Regular dental care: daily tooth brushing (or professional cleanings as advised) reduces systemic infection risk that can affect [heart disease](https://seniorpet.org/knowledge/cavalier-king-charles-spaniel-mitral-valve-disease "Heart Disease in Senior Pets").
- Weight check: weigh your Maltese monthly at home and report changes >10% to your vet.
Medication and supplement notes (safety-focused)
- NSAIDs: effective for osteoarthritis and post-op pain, but require baseline and periodic bloodwork (liver/kidney). Discuss interactions with amitraz, steroids, or certain antibiotics.
- Gabapentin: useful for neuropathic pain; dosing should be guided by your vet.
- Tramadol: variable efficacy in dogs; often used adjunctively.
- Corticosteroids: used for white shaker syndrome — long-term steroids can affect weight, glucose tolerance, and wound healing. Work closely with your vet to minimize dose and duration.
- Joint supplements and fish oil: choose veterinary products with verified purity. While evidence of benefit varies, omega-3 fatty acids have anti-inflammatory effects and are generally safe when dosed appropriately.
When is surgery recommended for a senior Maltese?
Consider surgery when:
- Lameness is persistent or progressive despite a conservative trial.
- There is frequent luxation causing pain or interfering with daily function.
- Radiographs show worsening osteoarthritis or deformity that surgical correction can address.
- Cardiac disease (advanced MVD) or uncontrolled airway disease makes anesthesia high-risk.
- Liver dysfunction (PSS) prevents safe anesthetic drug metabolism and cannot be managed.
Prevention: what owners of Maltese puppies and adults can do early
- Responsible breeding: because MPL has a genetic component, choosing breeders who screen breeding dogs for luxating patella reduces prevalence.
- Early orthopedic screening: have puppies and young adults examined for patellar stability; early detection allows lifestyle and conditioning adjustments.
- Maintain lean body condition from youth to reduce lifelong patellofemoral stress.
- Provide joint-supporting nutrition and age-appropriate exercise to promote balanced musculoskeletal development.

Monitoring and when to call your veterinarian
Call immediately if you notice:
- New or worsening lameness, inability to bear weight, or severe pain.
- Sudden collapse, labored breathing (possible CHF or airway collapse), or syncope.
- Change in appetite, vomiting, severe lethargy, or signs of bleeding (possible NSAID complication).
- New or worsening tremors if white shaker syndrome is suspected.
Closing thoughts
Maltese are long-lived and often resilient, but luxating patella can be a progressive condition that requires attentive, breed-specific care — especially in the senior years (8–9 years and beyond). Early detection, appropriate medical or surgical management, attention to comorbidities such as MVD and dental disease, and a comprehensive rehabilitation plan can preserve mobility and quality of life. Work closely with your veterinarian and, when indicated, with specialists (surgeon, cardiologist, rehabilitation therapist) to create a safe, effective plan tailored to your Maltese’s health status and lifestyle.
