Standard BRT and TTT were performed. Standardized CT measurements of the trochlear groove (width, depth, and area) and patella (recessed area) were performed preoperatively (T0), immediately postoperatively (T1), and at a 6-week re-examination (T6) with stifles in extended and flexed positions.<\/jats:p>\n                  <jats:p>Mean femoral trochlear area and depth increased significantly between T0\u2013T1, T1\u2013T6, and T0\u2013T6 (p\u2009&lt;\u20090.05). Mean recessed patellar area significantly increased between all time points when the stifle was flexed and between T0\u2013T1 and T0\u2013T6 when the stifle was extended (p\u2009&lt;\u20090.05).
