Comparison of Early Postoperative Step and Stair Counts With the Direct Anterior Approach Versus the Posterior Approach for Total Hip Arthroplasty.

Background: The purpose of this study was to evaluate the impact of direct anterior approach (DAA) or posterior approach (PA) on step and stair counts after total hip arthroplasty using a remotely monitored mobile application with a smartwatch while controlling for baseline characteristics.

Methods: This is a secondary data analysis from a prospective cohort study of patients utilizing a smartphone-based care management platform. The primary outcomes were step and stair counts and changes from baseline through one year.

Femoral Condyle Insufficiency Fracture After Total Knee Arthroplasty Using a Stemless Femoral Component With a Midlevel Constraint Articular Surface.

Midlevel constraint prostheses have provided increased varus/valgus and rotational stability for patients with severe deformity or ligamentous instability undergoing total knee arthroplasty (TKA). Here we present a series of 5 patients, 2 in detail, who underwent a primary TKA with a midlevel constraint articular surface and a primary femoral component without stem extension who all suffered isolated medial femoral condyle insufficiency fractures. All 5 TKAs were performed in females with both preoperative valgus deformity and flexion contractures.

Success of Various Marketing Strategies for a New-to-the-Area Orthopedic Practice.

Background Competition for patients among orthopaedic private practices, multi-specialty groups, and hospital systems continues to persist. An effective marketing campaign is essential for a practice to succeed in this competitive environment. The purpose of this study was to investigate the cost-effectiveness and efficacy of each marketing campaign and the influence of patient demographics on efficacy.

Patient Perception of Physician Attire in the Outpatient Setting During the COVID-19 Pandemic.

Introduction: In response to the SARS-CoV-2 pandemic, physician attire has evolved to incorporate personal protective equipment (PPE). Although PPE is mandated for all healthcare workers, variability exists in choice and availability. The purpose of this study was to determine patient perception of physician attire during the COVID-19 pandemic in an outpatient setting.

2021 John N. Insall Award: Aspirin is effective in preventing propagation of infrapopliteal deep venous thrombosis following total knee arthroplasty.

Aims: The optimal management of an infrapopliteal deep venous thrombosis (IDVT) following total knee arthroplasty (TKA) remains unknown. The risk of DVT propagation and symptom progression must be balanced against potential haemorrhagic complications associated with administration of anticoagulation therapy. The current study reports on a cohort of patients diagnosed with IDVT following TKA who were treated with aspirin, followed closely for development of symptoms, and scanned with ultrasound to determine resolution of IDVT.

Total Hip Arthroplasty in Patients With Avascular Necrosis After Hematopoietic Stem Cell Transplantation.

The immunosuppressive regimens required for hematopoietic stem cell transplantation predispose recipients to complications, including avascular necrosis. Cancer-related comorbidities, immunosuppression, and poor bone quality theoretically increase the risk for perioperative medical complications, infection, and implant-related complications in total joint arthroplasty. This study reviewed 20 primary total hip arthroplasties for avascular necrosis in 14 patients.

Same Day Total Hip Arthroplasty Performed at an Ambulatory Surgical Center: 90-Day Complication Rate on 549 Patients.

Background: There is an increasing interest in outpatient total hip arthroplasty (THA), as there are perceived benefits to the patient, insurer, and overall healthcare system. However, the safety of outpatient total joint arthroplasty has not been studied.

Methods: Five hundred forty-nine patients who underwent mini-posterior THA at a freestanding independent ambulatory surgical center (ASC) were reviewed.

The economic recession and its effect on utilization of elective total joint arthroplasty.

The United States economy entered a recession in December 2007. This study aims to determine whether the utilization of elective orthopedic surgeries has been impacted by this recession. From January 2007 to December 2009 at a single private practice in New Jersey, 4820 total joint replacement procedures were scheduled, of which 649 of those were cancelled.

Fracture of the proximal tibia after revision total knee arthroplasty with an extensor mechanism allograft.

Extensor mechanism reconstruction with an extensor mechanism allograft (EMA) remains one of the most reliable methods for treating the extensor mechanism deficient total knee arthroplasty. We report 3 patients who were treated with an EMA who sustained a proximal tibial shaft fracture. In all 3 cases, a short tibial component was present that ended close to the level of the distal extent of the bone block.

Gull-wing osteotomy for the treatment of the deficient patella in revision total knee arthroplasty.

Reconstruction of the deficient patella remains a challenge in revision total knee arthroplasty. Twelve consecutive patients who had a knee revision in which a nonresurfacable patella was treated with a gull-wing patellar osteotomy were followed using a computerized database. Radiographs revealed successful healing of the osteotomy in all patients with central tracking of the patella in the trochlear groove.

Total hip arthroplasty with a collarless, tapered, fiber metal proximally coated femoral stem: minimum 5-year follow-up.

The purpose of this study was to evaluate the midterm results, osteointegration potential, and implant-related complications of a cementless, collarless, proximally coated, distally tapered femoral hip prosthesis. The clinical and radiographic results for 129 hips in 116 patients after total hip arthroplasty with a Fiber Metal Taper (Zimmer, Inc ,Warsaw, Ind) femoral stem are reported. One hundred twenty-two (95%) hips were available for the minimum of 5 years clinical and radiographic follow-up.

Removal of a well-fixed trabecular metal monoblock tibial component.

The use of porous tantalum (Trabecular Metal; Zimmer, Inc, Warsaw, Ind) in hip and knee reconstruction has become increasingly popular over the past few years. Widespread clinical use of porous tantalum tibial components for primary total knee arthroplasty has been tempered in part by the perceived difficulty in removing this implant after bone ingrowth has occurred. We present an easy, reproducible, and inexpensive technique for removal of a well-fixed Trabecular Metal Monoblock Tibial Component (Zimmer), which has been used in 4 revision knees.

Interobserver and intraobserver reliability in lower-limb deformity correction measurements.

Planning for surgical correction of lower-limb deformity requires assessment of the character and extent of the deformity. Deformity measurements are defined; however, the reliability of these measurements has not been evaluated. This study was conducted to assess the interobserver and intraobserver reliability of lower extremity deformity measurements in the frontal and sagittal planes.
