Sreetha Sidharthan M.D. and I recently published this commentary about how posterior tibial tubercle relative to the trochlear groove is associated with increased risk of patellofemoral arthritis.
Arthritis of the patellofemoral compartment affects up to 24% of women and 11% of men over the age of 55 years who have symptomatic osteoarthritis of the knee. Recently, there has been interest in the sagittal TTTG distance,
which measures the position of the tibial tubercle with respect to the trochlear groove. This measurement is now being used in patients presenting with patellofemoral pain and/or cartilage pathology and may help guide surgical decision-making as we gain more data on how changing the tibial tubercle alignment relative to the patellofemoral joint can improve outcomes.
