Femoroacetabular Impingement Measurements Obtained From Two-Dimensional Radiographs Versus Three-Dimensional-Reconstructed Computed Tomography Images Result in Different Values.

Purpose: To compare the reliability and accuracy of radiographic measurements obtained from 2-dimensional (2D) radiographs and 3-dimensional (3D)-reconstructed computed tomography (CT) images in the assessment of femoroacetabular impingement syndrome (FAIS).

Methods: Consecutive patients with FAIS from January 2018 to December 2020 were identified and included in this study. Two fellowship-trained surgeons and 2 fellows performed blinded radiographic measurements.

Retrospective analysis of arthroscopic superior labrum anterior to posterior repair: prognostic factors associated with failure.

Background. The purpose of this study was to report on any prognostic factors that had a significant effect on clinical outcomes following arthroscopic Type II SLAP repairs. Methods.

Hip osseous morphology using computer navigation and plain radiographs.

In this study, we used 3-dimensional analysis to comprehensively map the osseous morphology of the acetabulum. Human cadaveric specimens were dissected to the joint capsule for computer navigation analysis. Data points outlining acetabular anatomy-determined using optical sensors-were translated into graphical environments.

Hip pain in active patients: what you may be missing.

When a patient who's physically active complains of hip pain, don't be too quick to label it a "hip pointer" that requires time and rest to heal. Consider this more nuanced-and effective-approach.

Articular and meniscal pathology associated with primary anterior cruciate ligament reconstruction.

Background: The abnormal kinematics, contact pressures, and repeated episodes of instability observed in chronic anterior cruciate ligament (ACL) deficiency suggest that these patients may be predisposed to early degenerative changes and associated pathologies such as meniscal tears and chondral injury. Injury to the cartilage and associated structures at the time of ACL rupture, in combination with the inflammatory mediators released at the time of injury, may create irreversible damage to the knee despite restoration of normal knee kinematics with an ACL reconstruction.

Hypothesis: Patients undergoing acute ACL reconstruction have a higher incidence of lateral meniscal tears and less severe chondral changes when compared with patients undergoing late ACL reconstruction.

Open versus arthroscopic distal clavicle resection.

Purpose: The purpose of this systematic review was to critically evaluate the available literature in an attempt to compare the outcome of open versus arthroscopic distal clavicle resection in the treatment of acromioclavicular joint pathology.

Methods: From January 1966 to December 2008, Medline was searched for the following key words: "acromioclavicular joint arthritis," "acromioclavicular osteolysis," "distal clavicle excision," "acromioclavicular joint excision," "Mumford," and "clavicle." Inclusion criteria included studies that compared the outcome of open versus arthroscopic distal clavicle resection.

Posterior hip pain in an athletic population: differential diagnosis and treatment options.

Context: Posterior hip pain is a relatively uncommon but increasingly recognized complaint in the orthopaedic community. Patient complaints and presentations are often vague or nonspecific, making diagnosis and subsequent treatment decisions difficult. The purposes of this article are to review the anatomy and pathophysiology related to posterior hip pain in the athletic patient population.

Lateral hip pain in an athletic population: differential diagnosis and treatment options.

Context: Historically, the term greater trochanteric pain syndrome has been used to describe a spectrum of conditions that cause lateral-sided hip pain, including greater trochanteric bursitis, snapping iliotibial band, and/or strains or tendinopathy of the abductor mechanism. Diagnosis of these conditions may be difficult because clinical presentations are variable and sometimes inconclusive. Especially difficult is differentiating intrinsic pain from pain referred to the greater trochanteric region.

Surgical management of articular cartilage defects in the knee.

The treatment of isolated cartilage lesions of the knee is based on several underlying principles, including a predictable reduction in the patient's symptoms, improvements in function and joint congruence, and prevention of progressive damage. Surgical options for cartilage restoration are described as palliative treatments, such as débridement and lavage; reparative, such as marrow stimulation techniques; or restorative, such as osteochondral grafting and autologous chondrocyte implantation. The choice of an appropriate treatment should be made on an individual basis, with consideration for the patient's specific goals (such as pain reduction or functional improvement), physical demand level, prior treatment history, lesion size and location, and a systematic evaluation of the knee that considers comorbidities, including alignment, meniscal status, and ligament integrity.

Does the literature confirm superior clinical results in radiographically healed rotator cuffs after rotator cuff repair?

Purpose: Because recurrent or persistent defects in the rotator cuff after repair are common, we sought to clarify the correlation between structural integrity of the rotator cuff and clinical outcomes through a systematic review of relevant studies.

Methods: Medline, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and the Cochrane Central Register of Controlled Trials were searched for all literature published from January 1966 to December 2008 that used the key words shoulder, rotator cuff, rotator cuff tear, rotator cuff repair, arthroscopic, integrity, healed, magnetic resonance imaging (MRI), computed tomography arthrography (CTA), and ultrasound. The inclusion criteria were studies (Levels I to IV) that reported outcomes after arthroscopic rotator cuff repair in healed and nonhealed repairs based on ultrasound, CTA, and/or MRI.

Arthroscopic stabilization for first-time versus recurrent shoulder instability.

Purpose: The purpose of this study was to systematically review the evidence on the outcomes of arthroscopic repair for anterior shoulder instability in first-time dislocators when compared with patients with recurrent instability.

Methods: We designed a systematic review with a specific methodology to investigate the outcomes of surgery for those with only a first-time dislocation versus those who underwent surgery after multiple instability events. We performed a literature search from January 1966 to December 2008 using Medline, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and the Cochrane Central Register of Controlled Trials.

Does the literature support double-row suture anchor fixation for arthroscopic rotator cuff repair? A systematic review comparing double-row and single-row suture anchor configuration.

Purpose: The purpose of this study was to compare the clinical outcome of single-row (SR) and double-row (DR) suture anchor fixation in arthroscopic rotator cuff repair with a systematic review of the published literature.

Methods: We searched all published literature from January 1966 to December 2008 using Medline, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and the Cochrane Central Register of Controlled Trials for the following key words: shoulder, rotator cuff, rotator cuff tear, rotator cuff repair, arthroscopic, arthroscopic-assisted, single row, double row, and transosseous equivalent. The inclusion criteria were cohort studies (Levels I to III) that compared SR and DR suture anchor configuration for the arthroscopic treatment of full-thickness rotator cuff tears.

Development of a new model for rotator cuff pathology: the rabbit subscapularis muscle.

Background And Purpose: The New Zealand white rabbit subscapularis tendon passes under a bony arch to insert on the lesser tubercle of the humerus in a manner analogous to the supraspinatus tendon in humans. We assessed whether this unique anatomy may provide a new animal model of the shoulder to improve our understanding of rotator cuff pathology.

Methods: The dimensions of the rotator cuff insertions (subscapularis, supraspinatus, and infraspinatus) were measured on 10 fresh frozen cadaveric New Zealand white rabbit shoulders.
