Original publication title: Extended proximal trochleoplasty for the correction of bidirectional patellar luxation in seven Pomeranian dogs.

Plain-English summary
Seven Pomeranian dogs were brought in for knee problems caused by bidirectional patellar luxation, which means their kneecaps were slipping out of place. A new surgical technique called extended proximal trochleoplasty was performed to correct this issue. After the surgery, 87.5% of the dogs showed good to excellent recovery, and all were able to return to normal function. There were only minor changes seen in their knee joints a year later, indicating a successful outcome.

Abstract
Seven Pomeranians with bidirectional patellar luxation (BPL) were prospectively studied regarding aetiology and results of a new surgical technique. Radiographic evaluation of the ratio between patellar ligament length and patellar bone length revealed no differences between Pomeranians with bidirectional patellar luxation and healthy stifle joints. Functional rather than anatomic patella alta might be associated with bidirectional patellar luxation in Pomeranians. The surgical outcome of extended proximal trochleoplasty was good-to-excellent in 87·5% of the stifles and all dogs achieved functional recovery. There was only minimal radiographic progression of osteophyte formation at 48 weeks after surgery. To the authors' knowledge, this is the first report on bidirectional patellar luxation in small breed dogs and its successful surgical treatment.
