Video Summary

Dr. Parikh asked about the definition of a "long trochlea" as an indication for groove plasty. The speaker explained that currently, there are no precise numeric measures to define long versus short trochlea, with assessments mostly subjective. A lateral condyle index from prior research suggests values under 0.9 indicate a short trochlea. Most dysplastic trochleas tend to be long. Complications like trochlear flap breakage highlight the need to understand how much trochlea is sufficient. The consensus is the need for multicenter studies to establish clear criteria, differentiate patient groups, and optimize surgical decisions.
