Femoroacetabular impingement (FAI) is a morphological hip condition that can lead to boney abutment of the proximal femur and acetabulum at the end ranges of hip motion. 1 , 2 When symptomatic, this condition is referred to as femoroacetabular impingement syndrome (FAIS). This language is gaining

Hip arthroscopy is a minimally invasive surgical procedure. Femoroacetabular impingement (FAI) is being increasingly recognized as a cause of hip pain in athletes and is a growing indication for arthroscopic surgery. Few studies have attempted to address patient views on outcome after arthroscopy, and no qualitative studies have been carried out to date.
To explore athletes' perceptions of rehabilitation outcome, the rehabilitative process, and return to sport and to gain insight into factors that affected this process.
A retrospective qualitative approach was adopted using semistructured interviews. Eight eligible participants were interviewed. Each had been treated with hip arthroscopy for FAI from September to November 2010. Data were audiotaped, transcribed verbatim, and analyzed using thematic analysis.
Three main themes emerged. (1) The ability to participate in sport; athletes were relatively satisfied with outcome despite some limitations in sporting ability. (2) Perceptions of hip problems; there was a lack of understanding and an association of hip problems with older people among the general public. (3) Athletes' perception of rehabilitation; athletes were dissatisfied with the rehabilitation and sought greater physiotherapy input.
Overall, athletes were relatively satisfied with their outcome 1 y after hip arthroscopy, despite some having to adapt their sporting activities. Key areas that need to be addressed in future research include factors affecting outcomes of hip arthroscopy, longer-term outcomes, perception of FAI among the public and health practitioners, and the development of a standardized evidence-based rehabilitation protocol.

Accurate measurements of in-vivo hip kinematics may elucidate the mechanisms responsible for impaired function and chondrolabral damage in hips with femoroacetabular impingement (FAI). The objectives of this study were to quantify the accuracy and demonstrate the feasibility of using dual fluoroscopy to measure in-vivo hip kinematics during clinical exams used in the assessment of FAI. Steel beads were implanted into the pelvis and femur of two cadavers. Specimens were imaged under dual fluoroscopy during the impingement exam, FABER test, and rotational profile. Bead locations measured with model-based tracking were compared with those measured using dynamic radiostereometric analysis. Error was quantified by bias and precision, defined as the average and standard deviation of the differences between tracking methods, respectively. A normal male volunteer was also imaged during clinical exams. Bias and precision along a single axis did not exceed 0.17 and 0.21 mm, respectively. Comparing kinematics, positional error was less than 0.48 mm and rotational error was less than 0.58°. For the volunteer, kinematics were reported as joint angles and bone-bone distance. These results demonstrate that dual fluoroscopy and model-based tracking can accurately measure hip kinematics in living subjects during clinical exams of the hip.
