Abstract A 7‐year‐old, male, neutered Bichon Frise presented with a 3‐month history of intermittent lameness 18 months post tibial plateau levelling osteotomy as treatment for cranial cruciate ligament rupture. On the physical examination, hyperextension of the right stifle joint was detected. Radiographic examination showed the patella was located distal to the femoral trochlea, and the patellar ligament was contracted and significantly shortened. Proximal tibial tuberosity transposition was performed using a tibial tuberosity advancement plate to restore the position of the patella. The aetiology of the patella baja and the surgical restorations are discussed in the report.
Vlachomitros et al. (Fri,) studied this question.
