title: Kite Shield-Shaped Wedge Recession for Treatment of Medial Patellar Luxation in Seven Small-Breed Dogs.
abstract: OBJECTIVE
  To document the trochlear depth (TD) and clinical outcome after kite shield-shaped wedge (K-wedge) recession trochleoplasty in toy-breed dogs with medial patellar luxation (MPL).
  
  
  METHODS
  Case series.
  
  
  METHODS
  Seven toy-breed dogs (<5 kg) with uni- or bilateral grades II-IV MPL (10 stifles).
  
  
  METHODS
  A K-wedge recession trochleoplasty was performed in all dogs in combination with other surgical procedures as treatment for MPL. The TD, the ratio of the proximal TD to patella thickness, and the presence of osteophytes were determined from computed tomography images taken pre-, and 1 and 12 months postoperative. Lameness scores and MPL grade were also recorded.
  
  
  RESULTS
  The TD and the ratio of proximal TD to patella thickness increased significantly immediately postoperative and remained increased at 1 and 12 months postoperative. The osteophyte score was significantly higher at 12 months postoperative than preoperative. All dogs had a reduction in MPL grade and improvement in lameness postoperative.
  
  
  CONCLUSIONS
  K-wedge recession trochleoplasty was successful in treating MPL in a series of toy-breed dogs and offers an alternate to other trochlear recession techniques.
