PURPOSE: We described patellofemoral alignment and trochlear morphology at one and five years after anterior cruciate ligament reconstruction (ACLR), and evaluated the associations between alignment and trochlear morphology (at one year) and worsening patellofemoral osteoarthritis (OA) features by five years. We also evaluated the associations between alignment and morphology to self-reported pain and function (Knee injury and Osteoarthritis Outcome Score, KOOS) at five years. MATERIALS AND METHODS: In this longitudinal observational study, we followed 73 participants (mean age 29 years, 40% women) from one- to five-years after ACLR. Using MRI, we measured alignment and morphology, and sc..View full abstract
