Introduction: Hip and knee arthroplasty are high volume, clinically successful, but costly orthopedic surgical procedures. There is significant variation in volume, outcomes, and cost at various hospitals. Methods: Using the Statewide Planning and Research Cooperative System (SPARCS) database to determine readmission rates and the New York State...

The management of meniscal root injuries has changed as biomechanical studies have demonstrated the importance of meniscal integrity in load distribution across the knee joint. Meniscal injury causes altered joint mechanics, which is postulated to be related to the onset of arthrosis. Arthroscopic meniscal root repair has been shown to restore more...

Simultaneous bilateral total knee arthroplasty (BTKA) is often performed to treat patients with disabling arthritis of both knees. Its use compared with staged procedures remains controversial. In a retrospective study, we compared 371 patients who had simultaneous BTKA with 67 patients who had staged (<6 months apart) BTKA. The staged procedures f...

Introduction: Ultrasonography offers a fast and inexpensive method to evaluate the rotator cuff in the office setting. However, the accuracy of ultrasound is highly user dependent. The purpose of this study is to investigate the learning curve of an orthopaedic surgeon in using ultrasound to diagnose rotator cuff tears. Methods: A sports medicin...

Meniscal root tears or avulsions compromise the biomechanical function of the menisci to a greater extent than simple meniscal tears do. As such, if left untreated, root injuries render the menisci incapable of properly distributing axial load and resisting rotation and translation. ➢ The clinical diagnosis of meniscal root abnormalities may be dif...

Favorable patient experience and low complication rates have been proposed as essential components of patient-centered medical care. Patients' perception of care is a key performance metric and is used to determine payments to hospitals. It is unclear if there is a correlation between technical quality of care and patient satisfaction. The study au...

Anterior cruciate ligament reconstruction (ACLR) has traditionally been reserved for young patients with functional instability. As the aging population continues to grow and embrace a more active lifestyle, it is important to determine if favorable outcomes of ACLR can be achieved in older adults. Patients greater than 50 years of age undergo- ing...

Introduction: The purpose of this study was to determine whether development of a hospital-acquired condition (HAC) affected responses to Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey questions. HCAHPS is a national, standardized satisfaction survey. Patient responses form, in part, the basis for Medicare reimbur...

Despite advances in thromboprophylaxis, venous thromboemb-olism remains a significant problem in major orthopaedic surgery, associated with significant morbidity and high cost of treatment. Virchow's triad, as well as patient and procedural risk factors, put many orthopaedic surgery patients at high risk. Diagnosis is based on clinical suspicion in...

Background: Patients with chronic exertional compartment syndrome who have failed nonoperative treatment are evaluated with pre-exertion and postexertion compartment pressure testing and may be treated with fasciotomy. Failure rates of up to 20% have been reported and may be related to factors such as age, sex, postexertion compartment pressures,...

laboratory comparison of a new arthroscopic transosseous rotator cuff repair to a double row transosseous equivalent rotator cuff repair using suture anchors. Bull Hosp Jt Dis. Abstract Background: Because current instrumentation makes it possible to perform an arthroscopic transosseous rotator cuff repair, we performed a biomechanical comparison o...

Psoriatic arthritis is a chronic inflammatory arthropathy that affects approximately 6% to 48% of patients with psoriasis. Arthritis is not correlated with the extent of skin disease. Classic radiographic findings of the involved joint include erosion, ankylosis, and fluffy periostitis. Site-specific characteristic deformities such as pencil-in-cup...

Background: Dislocation of the sternoclavicular joint is a rare injury that has a low incidence of signifcant long-term symptoms. Surgical reconstruction of the joint is indicated in patients with symptomatic, chronic anterior instability or with irreducible or recurrent posterior instability. There have been many reported techniques for stabiliza...

Meniscal allograft transplantation (MAT) has become an accepted treatment option for patients undergoing meniscectomy with recalcitrant pain in the corresponding compartment. Whether MAT can oppose cartilage degeneration is unclear. Our purpose was to perform a systematic review of available literature to answer the following: (1) Does MAT prevent...

Mechanical obstacles may infrequently impede closed reduction of anterior shoulder dislocation. Imaging techniques such as arthrography, computed tomography (CT) and magnetic resonance imaging (MRI) complement conventional radiography by allowing identification of obstacles to reduction. We present a case of irreducible anterior glenohumeral disloc...
