Video Transcription

Video Summary

In this video, the presenter discusses the influence of sagittal alignment of the tibial tubercle on patellofemoral cartilage lesions. They conducted a retrospective analysis of patients undergoing patellofemoral cartilage repair or restoration procedures. Three groups were formed: patients with cartilage lesions, patients with normal patellofemoral cartilage, and patients with asymptomatic patellar chondrosis. The vertical tibial tubercle trochlear groove distance (VTTG) was measured, and it was found that patients with cartilage lesions had a significantly higher VTTG measurement compared to the other two groups. The presenter suggests that VTTG could be a useful measurement for osteotomy planning in the future.
