Key result
Femoroacetabular impingement was associated with predominantly Mode 1 labral tears (72%), whereas severe dysplasia was associated with predominantly Mode 2 tears (75%).
Observational (n=68)
Absolute Event Rate: 72% vs 25%
Hip pathology (FAI vs dysplasia) is significantly related to the location and mode of labral tears, with Mode 1 tears potentially increasing the risk of adjacent acetabular cartilage damage.
No takes yet. Share an insight, caveat, or question.
Tear mode patterns by hip morphology may refine arthroscopic planning; leaves open effects on cartilage damage and need for tailored interventions.
Tamura et al. (2013) conducted an observational in Dysplastic hips and femoroacetabular impingement (n=68). Femoroacetabular impingement vs. Severe dysplastic hips was evaluated on Prevalence of Mode 1 versus Mode 2 labral tears. Femoroacetabular impingement was associated with predominantly Mode 1 labral tears (72%), whereas severe dysplasia was associated with predominantly Mode 2 tears (75%).
