Abstract
Introduction and purpose: Femoroacetabular impingement (FAI) has become a well-recognized pathological condition over the last few years and different authors have published good results obtained after surgical treatment using osteoplasty. In this study we analyze the clinical and functional results seen in the first one hundred patients subjected to osteoplasty using a minimally invasive anterior approach.
Materials and methods: We analyzed the first 107 patients treated with a mean follow-up of 26 months (range: 6–41). They are assessed on a scale we drew up ourselves that takes into account the Impingement Test, the Merle D’Aubigné scale and the WOMAC score at 6 weeks, 3 months, 6 months and once a year. Results are classified according to these variables as excellent, good, fair and poor and are analyzed using the chi-square test (SPSS software, p< 0.05). Excellent and good results are considered satisfactory, the others are not.
Results: At 1 year satisfactory results are seen in 91.3 % of Tönnis 1 cases and 93.4% of Tönnis 0 cases; these results are maintained during the second year in 85.1% (p=0.375). On the other hand, in Tönnis 2 cases, only 55.3% good results are seen at 2 years. These differences were significant (p< 0.017).
Conclusions: Treatment of impingement by means of femoroacetabular osteoplasty using our minimally invasive approach results in a high proportion of satisfactory outcomes, especially during stages 0 and 1. However, such is not the case in stage Tönnis 2 cases. Therefore, it is advisable to use this procedure in symptomatic patients during the incipient stages of the condition.
