Abstract

Objective

To describe the clinical findings of dogs that sustained patellar fractures after tibial plateau leveling osteotomy (TPLO).

Study Design

Retrospective case series.

Animals

Dogs with patellar fractures that occurred after TPLO surgery (n = 6).

Methods

Medical records (November 1, 2008–October 31, 2010) were reviewed to identify dogs with patellar fracture occurring after TPLO.

Results

Six of 305 (2%) dogs had a patellar fracture after TPLO; 5 dogs were clinically lame when the fracture was diagnosed and all had radiographic evidence of patellar tendon thickening. All dogs were treated nonsurgically. In 2 dogs where follow-up radiographs were available there was no evidence of fracture union. No dog had a persistent lameness.

Conclusion

Fracture of the patella is an uncommon complication of TPLO surgery. Nonsurgical management can provide a satisfactory functional outcome.
