Five dogs with bilateral patellar luxation were presented at the Small Animal Hospital of Faculty of Veterinary Medicine, Chulalongkorn University.

Four dogs had grade 2, 3, and 4 medial patellar luxation in 3, 3, and 2 stifle joints, respectively. One dog had grade 3 bilateral lateral patellar luxation that had recurrent patellar luxation of left stifle joint for 6 months after previous surgery. All dogs had surgical treatment to re-align and stabilize extensor mechanism in the normal position.

The dogs received anti-inflammatory drug and PCSO-524® in combination with rehabilitation to restore normal limb function and muscle mass postoperatively. All dogs achieved good outcomes when compared with pre-operation. Range of motion was normal in all dogs and the patellae were in the normal position.

However, one stifle with previous reluxation and severe osteoarthritis had slightly crepitation when flexed and extended the stifle joint. Patellar luxation causes abnormal wear of the patella and trochlear ridges leading to lameness, muscle pain, and osteoarthritis.

The treatment focuses on stabilization of the stifle joint and restore limb function. Surgical treatment is recommended in most cases. Rehabilitation provides strengthen muscle, improves normal joint function, enhanceslimb function, and prevents complications.

Despite successful treatment for correcting patellar luxation, osteoarthritis remains occurrence in most cases.

Therefore, use of anti-inflammatory supplement such as PCSO-524® is important for long-term management with less side effect and safety for long-term use when compared with non-steroidal anti-inflammatory drugs.
