Direct Anterior Approach (DAA) is known to cause damage to the TFL during the surgical approach, the point of this study is to evaluate the impact between the severity of the per operative TFL damage and the functional short term results.
adult (>18 years old),
patient undergoing primary Total Hip Arthroplasty through Direct Anterior Approach for osteoarthritis
hip dysplasia
leg length discrepancy greater than 2cm
history of homolateral hip surgery
neuromuscular pathology
Single group
Data collection and self-administered questionnaire
Other interventionData collection and self-administered questionnaire (HHS and SF-36)
Correlation between post operative functional results and TFL muscle damage
Correlation between : * short term post operative functional results, evaluated by Harris Hip score at 6 weeks. Harris Hip score has 10 items with several propositions per each item and total score from 2 to 100 , and * TFL muscle damage grade during surgery evaluated with ATHLAS classification : score 0 (intact or few fibres), 1 (0-25% of fibres), 2 (25-50%), 3 (50-75%) et 4 (\>75%)
Harris Hip score 6 months
Result of Harris Hip score at 6 months Harris Hip score has 10 items with several propositions per each item and total score from 2 to 100 ,
Quality of life scale
Evolution of SF-36 questionnaire score between 6 weeks and 6 months after total hip arthroplasty
