Medical complications (eg, surgical site infection and deep vein thrombosis), readmission rates, and extended hospital stay within 30 days of the procedure were recorded.

The operative time for concomitant MPFLR and TTO was significantly longer (122 \u00b1 45 minutes) compared with isolated MPFLR (97 \u00b1 55 minutes; P &lt; .001) and isolated TTO (89 \u00b1 51 minutes; P &lt; .001). There were 32 AEs (3.6%), with 10 AEs in the isolated TTO group (5.9%), 18 AEs in the isolated MPFLR group (2.9%), and 4 AEs in the MPFLR + TTO group (4.2%). There was no significant difference in the rate of AEs between the isolated MPFLR and isolated TTO groups ( P = .1), isolated MPFLR and MPFLR + TTO groups ( P = .5), and isolated TTO and MPFLR + TTO groups ( P = .8). Diabetes mellitus was associated with an increased risk of developing an AE (odds ratio, 4.0; P = .003), and hypertension resulted in an increased risk of an extended hospital stay (odds ratio, 4.0; P
