Rotational instability was defined as persistence of a positive tibial pivot test (TPT) after TPLO requiring placement of an antirotational suture. Signalment, clinical findings, radiographic variables, and intraoperative data were compared between rotationally unstable and stable stifles.

Postoperative rotational instability was identified in 77 of 312 stifles (24.6%). In multivariable analysis, chronic presentation was associated with lower odds of instability (OR, 0.41; 95% CI, 0.20 to 0.85). Increasing lameness severity (OR, 1.54\/grade increase; 95% CI, 1.07 to 2.24), complete CrCL rupture (OR, 23.48; 95% CI, 6.50 to 152.25), and meniscal tear (OR, 2.68; 95% CI, 1.26 to 5.88) were associated with higher odds of instability.
