Objective: To quantify the radial and lateral extents of femoral cam lesions in FAI patients relative to the alpha angle and correlate with clinical data.
Methods: Retrospective study of 81 hips with femoral cam morphology that underwent arthroscopic surgery between 2017 and 2019. At each hour over the clockface, the alpha angle (α) (abnormal defined as > 55°), radial extent, and lateral extent of cam lesions were measured on CT.
Background: While excision of the trochanteric bursae to treat lateral hip pain has increased in popularity, no comparison exists between the surgical outcomes and complications of the open and arthroscopic techniques involving trochanteric bursectomy. The purpose of this study was to determine the efficacies and complication rates of arthroscopic and open techniques for procedures involving trochanteric bursectomy.
Methods: The terms "trochanteric," "bursectomy," "arthroscopic," "open," "outcomes," and "hip" were searched in five electronic databases.
Background: Ultrashort echo time (UTE) T2* is sensitive to molecular changes within the deep calcified layer of cartilage. Feasibility of its use in the hip needs to be established to determine suitability for clinical use.
Purpose: To establish feasibility of UTE T2* cartilage mapping in the hip and determine if differences in regional values exist.
Cognitive Training in Orthopaedic Surgery.
J Am Acad Orthop Surg Glob Res Rev
March 2021
Introduction: Over the past two decades, various factors have led to fewer opportunities for hands-on learning in the operating room among orthopaedic surgery trainees. Innovative training platforms using anatomic models, cadaveric specimens, and augmented reality have been devised to address this deficiency in surgical training, but such training tools are often costly with limited accessibility. Cognitive training is a low-cost training technique that improves physical performance by refining the way in which information is mentally processed and has long been used by professional athletes and world-class musicians.

Materials And Methods: Retrospective study on 20 consecutive FAI patients with a preoperative CT who underwent arthroscopy from October 2016 to September 2017. A 3D virtual dynamic hip model was created from the CT.
Background: Youth sports specialization has become more prevalent despite consequences such as increased injury rates and burnout. Young athletes, coaches, and parents continue to have misconceptions about the necessity of sports specialization, giving athletes the encouragement to focus on a single sport at a younger age.
Purpose: To characterize the motivations for specialization and determine when elite athletes in various individual and team sports made the decision to specialize.
Purpose: To determine the prevalence of preoperative opioid use in patients with femoroacetabular impingement (FAI) syndrome and to define how opioid use influences preoperative hip pain and function at a single center.
Methods: Between February 2015 and September 2016, patients undergoing hip arthroscopy at a single Midwest institution for FAI syndrome were retrospectively reviewed. Patients undergoing arthroscopy for non-FAI conditions and those with undocumented preoperative opioid use were excluded.
Objective: The purpose of this study was to determine the effect that preoperative use of 3D printed models has on planned osteoplasty for femoroacetabular impingement (FAI) surgery.
Materials And Methods: This experimental study utilizing retrospective data included 10 consecutive patients from July 1, 2013, to January 1, 2015, with a clinical diagnosis of FAI and imaging consisting of radiographs, CT scans, and MR images. Three-dimensional models of each patient's affected hip were printed to scale from CT data.
Background: Specialization in young athletes has been linked to overuse injuries, burnout, and decreased satisfaction. Despite continued opposition from the medical community, epidemiological studies suggest the frequency is increasing.
Hypothesis: Extrinsic pressures in addition to individual aspirations drive this national trend in sports specialization.
Background: Youth athlete specialization has been linked to decreased enjoyment, burnout, and increased injury risk, although the impact of specialization on athletic success is unknown. The extent to which parents exert extrinsic influence on this phenomenon remains unclear.
Purpose/hypothesis: The goal of this study was to assess parental influences placed on young athletes to specialize.
Since 2015, the Multicenter Orthopedic Outcomes Network (MOON) has addressed several factors associated with patient outcome after anterior cruciate ligament (ACL) injury. These factors include predictors of high grade knee laxity, the impact of meniscus treatment on joint space narrowing after surgery, graft selection, treating diabetic patients, predictors of clinically significant pain, and outcomes of patients where meniscus tears were left in situ without treatment. The presence of meniscus tears and generalized laxity predict a lax examination under anesthesia prior to surgery.
