Knee Research
Statistical Fragility and the Role of P Values in the Sports Medicine Literature
Introduction: Comparative trials evaluating categorical outcomes have important implications on surgical decision making. The purpose of this study was to examine the statistical stability of sports medicine research.
Fresh Femoral Condyle Allograft Transplant for Knee Osteonecrosis in a Young, Active Patient
Osteonecrosis is caused by diminished microperfusion of bone resulting in subsequent joint collapse. Estimates suggest that roughly 20,000 to 30,000 new cases are diagnosed annually in the United States, with even higher rates in other countries.
Anterior Cruciate Ligament Reconstruction With Achilles Tendon Allograft in a Patient With Ehlers-Danlos Syndrome
Ehlers-Danlos Syndrome (EDS) can cause recurrent dislocation and subluxation of joints due to ligamentous and capsular laxity, often leading to surgical interventions. Graft choice for ACL reconstruction is particularly important for EDS patients, since autograft options will increase risk of failure due to the abnormally lax tissue quality in these patients; however, few studies discuss considerations for EDS patients undergoing ACL reconstruction.
Medicaid Health Insurance Status Limits Patient Accessibility to Rehabilitation Services Following ACL Reconstruction Surgery
Background In the senior author’s (X.L.) orthopaedic sports medicine clinic in the United States (US), patients appear to have difficulty finding physical therapy (PT) practices that accept Medicaid insurance for postoperative rehabilitation. Purpose To determine access to PT services for privately insured patients versus those with...
Insurance Status Affects In-Hospital Complication Rates After Total Knee Arthroplasty
Insurance status has been shown to be a predictor of patient morbidity and mortality. The purpose of this study was to evaluate the effect of patient insurance status on the in-hospital complication rates following total knee arthroplasty. Data were obtained from the Nationwide Inpatient Sample (2004 through 2011).
Patellofemoral pain syndrome in female athletes: A review of diagnoses, etiology and treatment options
Patellofemoral pain syndrome (PFPS) is one of the most common causes of knee pain and is present in females disproportionately more relative to males. PFPS causes tend to be multifactorial in nature and are described in this review. From a review of the current literature, it is clear that there needs to be further research on PFPS in...
Extensor Mechanism Reconstruction for Chronic Patellar Fracture
Patients with displaced patellar fractures typically present with disruption to the extensor mechanism requiring acute surgical intervention. Chronic patellar fractures with disruption of the extensor mechanism are uncommon, and few surgical options are available. The authors present a patient who sustained a fracture to the inferior pole..
Understanding Magnetic Resonance Imaging of Knee Cartilage Repair: A Focus on Clinical Relevance
The aims of this review article are (a) to describe the principles of morphologic and compositional magnetic resonance imaging (MRI) techniques relevant for the imaging of knee cartilage repair surgery and their application to longitudinal studies and (b) to illustrate the clinical relevance of pre- and postsurgical MRI with...
Allograft tissue irradiation and failure rate after anterior cruciate ligament reconstruction: A systematic review
Aim: To evaluate whether anterior cruciate ligament (ACL) allograft irradiation is effective for sterility without compromising graft integrity and increasing failure rate. Methods: A literature search was conducted using PubMed, Cochrane, and Google. The following search terms were used: "Gamma irradiation AND anterior...
Unusual Presentation of Anterior Knee Pain in Elite Female Athletes: Report of Two Cases
Two elite female athletes presented with anterior knee pain with range of motion and reproducible tenderness to palpation. Diagnostic arthroscopy was performed in both cases resulting in excision of a nodular pigmented villonodular synovitis (PVNS) in the first patient and scar tissue in the second patient. Correct diagnosis of...
