Comparison of complication rates of unilateral, staged bilateral, and single-session bilateral surgery for the treatment of bilateral medial patellar luxation in dogs

Fullagar BA, Rajala-Schultz P, Hettlich BF. Can Vet J. 2017 Jan; 58 (1): 39-44.

This retrospective study compared complication rates in 93 client-owned dogs (119 stifles) undergoing single-session bilateral, staged bilateral, or unilateral surgery for bilateral medial patellar luxation.
Clinical characteristics and complication rates were compared and risk factors for major complications were explored.

Sixty-five dogs had unilateral, 16 staged bilateral and 11 single-session bilateral surgery. Complications occurred in 28/119 stifles (24%), 11 (9%) of which required revision surgery. Patellar reluxation occurred in 7/119 (6%) stifles, with no revision required. There was no significant association between timing of surgery and incidence of complications.

In dogs < 10 kg with bilateral medial patellar luxation, single-session bilateral surgery is a feasible treatment option with a complication rate comparable to staged bilateral or unilateral medial patellar luxation surgery.
