Regarding “Tibial Tubercle Trochlear Groove/Trochlear Width Is the Optimal Indicator for Diagnosing a Lateralized Tibial Tubercle in Recurrent Patellar Dislocation Requiring Surgical Stabilization”

I read with great pleasure the recently published study “Tibial Tubercle Trochlear Groove/Trochlear Width Is the Optimal Indicator for Diagnosing a Lateralized Tibial Tubercle in Recurrent Patellar Dislocation Requiring Surgical Stabilization.”1 I write this letter not only to praise Dr. Su and the coauthors but also to spotlight their study and draw more attention to it. They thoroughly studied the multiple imaging measurements for tibial tubercle lateralization and demonstrated with clear statistical evidence that the ratio tibial tubercle to trochlear groove (TT-TG) distance divided by the trochlear width, first published by Camp et al.,2 is the best and most efficient indicator for determining tibial tubercle lateralization.
