Functional results of hip arthroscopy without capsule closure: 3 years of follow up.



To evaluate the functional outcome of patients that underwent hip arthroscopy by femoroacetabular impingement (FAI) at three years of follow-up.

Material And Method

Cohort study. We included patients operated between June 2013 and June 2014 with a diagnosis of FAI in which acetabuloplasty, femoral osteochondroplasty, labrum repair and "T" capsulotomy without capsular closure were performed. Hyperlaxity patients, borderline dysplasia, pure cam impingement, pure pincer impingement and patients with Tonnis 2 or greater were excluded. Twenty-nine patients were identified. Harris Hip score modified, Oxford scale, Tegner scale and SF36 were used as measuring instruments. Results are presented with median and, range () and interquartile range []. To compare the functional results by gender, a comparison test of unpaired median was used, using a 0.05 significance with Stata v11.2 statistics program (StataCorp LP, College Station, Texas, USA).


Twenty patients (68%), twelve women and nine men were recruited. The median age was 33 years (18-52). Fifteen (75%) patients maintained or improved their sports level, Seventeen (85%) patients obtained good-excellent results by Oxford scale and fifteen (75%) excellent good results by Harris-Hip scale. In SF36, the median of the physical component was 80 points [71-91] and the mental component 78 points [66.96]. There is a trend towards better functional results in all the scales used in men patients, without reaching statistically significant differences. No patient required revision of arthroplasty or total hip arthroplasty.


Capsular management is currently a subject of debate, given that it shows better functional results in the short term. The capsular closure impresses that it is of greater importance in women.
