Seven (9.1%) patients experienced a patellar fracture at a mean of 34 (range 16-64) months postoperatively. All were treated nonoperatively. Lower BMI (P = 0.03), change in patellar thickness (P < 0.001), amount of bone resected (P = 0.001), and larger trochlear component size (P = 0.01) were associated with a greater incidence of fracture. Fewer fractures occurred when the postoperative patellar height exceeded the preoperatively measured height. No statistically significant differences were found in outcome scores between groups at mean four-year follow-up.<p> Surgery 10.1016/j.arth.2015.02.007 11706 Adverse Effects 2022-02-21T22:48:57.408-06:00 Injuries Patellar fracture following patellofemoral arthroplasty 17992
