Results confirmed the efficacy and low associated morbidity of arthroscopy in the management of femoroacetabular impingement. Short-term functional results matched those of the literature. Planning and assessment seem not yet to be fully standardized. Preoperative osteoarthritis on X-ray was associated with poorer functional results. This attitude does not seem to be indicated for hips showing evolved osteoarthritis (>grade 1).
Purpose The aim of the study was to compare three different procedures performed by the same surgeon: monobundle patellar tendon reconstruction (bone-patellar tendonbone, BPTB), double-bundle hamstring reconstruction (DBH) and mono-bundle patellar tendon combined with extraarticular reconstruction (Lemaire) (BPTB + L). Methods A total of 75 patients (25 in each group) were evaluated at a mean follow-up of 25 months. Laxity was assessed pre-and post-operatively with Telos™ stress radiographs (15 kg). The amount of anterior tibial translation (ATT) corrected by the surgery was quantified. Secondary outcomes were International Knee Documentation Committee (IKDC) scores, pivot shift grading, pain complaints, sensory deficits, subsequent surgical procedures, return to sports and patients' ability to kneel or squat on their affected knee. Results Absolute correction of ATT for the internal compartment was not statistically significant [analysis of variance (ANOVA), p=0.377]. For the external compartment BPTB + L (8.2 mm) showed superiority over DBH (5.6 mm) and BPTB (4
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
