Opening wedge high tibial osteotomy (OWO) is known to change the kinematics of both the tibiofemoral and patellofemoral joints; however, it is not known if this change in kinematics is associated with a change in patellar cartilage health over time. Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) was used as an indicator of cartilage health before surgery, 6 months post-op, and 12 months post-op (n=14). Our results show that there is a statistically significant increase in dGEMRIC T1 score between 6 and 12 months post-op. This may indicate that there is no adverse effect on patellar cartilage health following OWO.
