Medial Patellar Luxation (MPL) Surgery in Farmington, NM
Medial Patellar Luxation, or MPL, occurs when the kneecap moves out of its normal position. This condition can cause skipping, limping, pain, or difficulty using the affected leg, and surgery may be recommended in more significant cases to improve joint alignment and long-term comfort.
Book OnlineMPL is one of the most common orthopedic conditions in dogs, particularly in smaller breeds, though it can affect dogs of any size. It occurs when the groove that normally holds the kneecap (patella) in place is too shallow or misaligned, allowing the kneecap to slip out of position, most often toward the inside of the leg.
Signs of medial patellar luxation include:
- Intermittent skipping or “hopping” while walking or running
- Sudden holding up of a rear leg, followed by normal walking again
- Progressive stiffness or reluctance to jump
- Visible abnormal leg positioning in more advanced cases
MPL is graded on a scale from 1 to 4 based on severity, with grade 1 causing occasional, mild symptoms and grade 4 involving a kneecap that is permanently out of place. Mild cases may be managed with weight management and activity modification, while moderate to severe grades typically benefit from surgical correction to realign the kneecap and prevent long-term joint damage or arthritis. Diagnosis usually involves a physical exam to assess the grade of luxation, sometimes combined with X-rays to evaluate the joint structure.
If your dog has a skipping gait or intermittently holds up a rear leg while walking, don’t wait for it to worsen. Call (505) 326-2205 to schedule an evaluation.
Frequently Asked Questions
What does medial patellar luxation look like in dogs?
The most common sign is an intermittent skipping or hopping gait, where the dog briefly holds up a rear leg before walking normally again.
Are small breed dogs more prone to MPL?
Yes, MPL is most common in smaller breeds, though it can occur in dogs of any size.
Does MPL always require surgery?
Not always. Mild cases (grade 1) may be managed with weight control and activity modification, while moderate to severe cases typically benefit from surgical correction.
How is MPL graded?
MPL is graded from 1 to 4 based on severity, ranging from occasional mild slipping (grade 1) to a kneecap that is permanently out of place (grade 4).
What happens if MPL is left untreated in more severe cases?
Untreated moderate to severe MPL can lead to progressive joint damage, arthritis, and worsening mobility over time.
How is MPL diagnosed?
Diagnosis typically involves a physical exam to assess the grade of luxation, sometimes combined with X-rays to evaluate the joint structure.
How long is recovery after MPL surgery?
Recovery generally takes several weeks, with a structured rehabilitation plan to help your dog regain strength and mobility in the affected leg.
