Background: Physical therapy remains a ubiquitous treatment modality for the management of frozen shoulder (adhesive capsulitis) despite limited high-level evidence supporting its use. Leveraging patient-reported outcome measures (PROMs) and healthcare costs, this study compared patient outcomes and value achieved through watchful waiting (WW) versus physical therapy (PT) for conservative management of frozen shoulder.
Methods: Patients in this prospective, parallel randomized controlled trial who were diagnosed with frozen shoulder were randomized 1:1 to WW or PT.

Background: The indications for hip arthroscopy in patients aged ≥40 years remain controversial, as observational studies have suggested that advanced age portends poor functional outcomes, poor durability of improvement, and high rates of conversion to total hip arthroplasty.
Purpose: To compare hip arthroscopy versus nonoperative management for symptomatic labral tears in patients aged ≥40 years with limited radiographic osteoarthritis.
Study Design: Randomized controlled trial; Level of evidence, 1.
Introduction: Lumbar facet cysts represent a potential source of nerve root compression in elderly patients. Isolated decompression without fusion has proven to be a reasonable treatment option in properly indicated patients. However, the risk of lumbar fusion after isolated decompression and facet cyst excision has yet to be elucidated.

Puncture capsulotomy preserves capsuloligamentous integrity by avoiding iatrogenic transection of the iliofemoral capsular ligament.
View Article and Find Full Text PDFBackground: No prior work has explored whether the presence of degenerative spondylolisthesis impacts patient-reported outcome measurements (PROMs) after an anterior cervical discectomy and fusion (ACDF); therefore, the goal of the current study was to determine whether the presence of a spondylolisthesis affects PROMs after an ACDF.
Methods: A retrospective cohort study was conducted on patients over the age of 18 who underwent a 1- or 2-level ACDF. All patients received preoperative standing lateral x-rays and were placed into 1 of 2 groups based on the presence of cervical spondylolisthesis from C2-T1: (1) no spondylolisthesis (NS) group or (2) spondylolisthesis (S) group.
Study Design: This was a multicenter retrospective cohort study.
Objective: The purpose of this study was to compare the surgical and radiographic outcomes of patients undergoing posterior cervical fusion (PCF) with constructs extending from C2 to T2 to patients with constructs extending from C3 to T1.
Summary Of Background Data: Limited evidence exists regarding the appropriate level of proximal and distal extension of PCF constructs.
Study Design: Retrospective cohort study.
Objective: To investigate the clinical and radiographic differences between patients who underwent anterior lumber interbody fusion (ALIF) with either open or percutaneous posterior fusion for lumbar isthmic spondylolisthesis.
Summary Of Background Data: Circumferential fusion for isthmic spondylolisthesis is commonly performed with superior clinical outcomes, fusion rates, and restoration of sagittal balance when compared to posterior fusion alone.
Background: While the impact of trainee involvement in other surgical fields is well established, there is a paucity of literature assessing this relationship in orthopaedic spine surgery. The goal of this study was to further elucidate this relationship.
Methods: A retrospective cohort study was initiated on patients undergoing 1-3 level lumbar spine fusion at a single academic center.
Purpose: To evaluate the short-term outcomes of endoscopic repair of full-thickness gluteus medius and minimus tendon tears with a minimum of 2-year follow-up and add to the paucity of literature on abductor tendon tears.
Methods: All patients who underwent endoscopic abductor tendon repair between December 2013 and August 2017 were prospectively evaluated. The inclusion criteria for this study were primary full-thickness gluteal tendon tears and at least 2-years of follow-up.
The purpose of this study was to evaluate the histologic features of the caprine labrum, with emphasis on the chondrolabral junction, with the goal of informing the feasibility of the goat as an animal model. The left hip joint of six adolescent Spanish goats (Capra pyrenaica) was harvested and subjected to anatomical and histological assessments. Human acetabular and femoral head samples, collected during total hip arthroplasty, served as comparison samples.

Post-operatively, the patient's symptoms worsened, and she lost the ability to bear weight. Follow-up MRI revealed previously absent, diffuse STIR hyperintensity in the tibia extending far beyond the surgical site.
View Article and Find Full Text PDFBackground: Acetabular labral tears are increasingly recognized as a source of hip pain in a younger active population. Given the significant focus on surgical intervention, there has been limited investigation on the nonsurgical management and natural history of such injuries.
Hypothesis: Patients undergoing nonsurgical treatment for symptomatic acetabular labral tears experience functional improvement based on patient-reported outcome measures over the course of 1 year.
Introduction: In this study, the prognostic value of osteoarthritis (OA) on the overall failure rate, pain, and function of surgical management of femoroacetabular impingement (FAI) was evaluated via meta-analysis.
Methods: Relevant comparative studies were obtained from PubMed, OVID, and Cochrane database up until April 2016. Studies were selected according to the eligibility criteria.
The prevalence of hip arthroscopy has increased exponentially with the advent of arthroscopic labral repair techniques for femoroacetabular impingement. The goal of arthroscopic labral repair is to re-create the anatomic suction seal of the labrum against the femoral head. This important anatomic relationship has been demonstrated in several biomechanical studies.
View Article and Find Full Text PDFWe describe an arthroscopic technique for the treatment of labral pathology and femoroacetabular impingement that provides excellent access to the central and peripheral compartments while preserving the biomechanically crucial components of hip joint stability. The hip capsule and the ligaments within it have been shown to be integral to hip biomechanical stability. Other popular techniques such as interportal and T-capsulotomy inherently damage the capsuloligamentous complex of the hip and can be associated with postoperative gross instability, micro-instability, heterotopic ossification, and seroma.
View Article and Find Full Text PDFThe surgical approach for open reduction and internal fixation of lateral condyle fractures in children is controversial. Some authors recommend the lateral approach to the elbow over the posterior approach because of theoretical concern for injury to the vascular supply of the distal humerus and potential avascular necrosis (AVN). The purpose of this retrospective case series study is to report the outcomes of open reduction and internal fixation of displaced lateral condyle fractures of the humerus by the posterior approach.
View Article and Find Full Text PDFA novel technique of "anterior offsetting" of the humeral head component to address posterior instability in total shoulder arthroplasty has been proposed, and its biomechanical benefits have been previously demonstrated experimentally. The present study sought to characterize the changes in joint mechanics associated with anterior offsetting with various amounts of glenoid retroversion using cadaver specimen-specific 3-dimensional finite element models. Specimen-specific computational finite element models were developed through importing digitized locations of six musculotendinous units of the rotator cuff and deltoid muscles based off three cadaveric shoulder specimens implanted with total shoulder arthroplasty in either anatomic or anterior humeral head offset.
View Article and Find Full Text PDFRestoration of joint stability during total shoulder arthroplasty can be challenging in the face of severe glenoid retroversion. A novel technique of humeral head component anterior-offsetting has been proposed to address posterior instability. We evaluated the biomechanical benefits of this technique in cadaveric specimens.
