Active clinical trials for "Osteoarthritis"

This study is a prospective validation study of a new hip and knee replacement-specific questionnaire that can be used to predict postoperative complications. The purpose of this study is to confirm the validity of a new hip and knee scoring system to be used as a clinical tool to predict potential complication rates in patients undergoing total hip or knee replacement surgery. This scoring system aims to stratify patients into specific risk categories based a standardized calculated score. Patients will be evaluated on health risk factors and severity of disease on radiographic imaging prior to surgery, associated to higher complication rates following surgery. The hopeful anticipated result of this study is a prospective validation of the scoring system with both statistical and clinical significance in predicting postoperative complication rates in patients with moderate to high health risk, This stratification system may prove meaningful by allowing these patients, especially those classified as High-Risk, to be incorporated into more appropriate healthcare bundle payment systems that account for their higher financial demands. Furthermore, the stratification may allow for preoperative counseling and a shift towards non-operative management, or surgeon-patient conversations regarding the need to modify a portion of their objective risks prior to surgical intervention. Predictive risk models such as the one presented in the current study will be essential tools as the number of total hip arthroplasty procedures performed each year continue to increase and both the numbers of procedures and associated complications impose a significant cost on the U.S. healthcare system.

Objective: To study the feasibility and validity of a two-step telephone screening procedure for symptomatic knee and hip osteoarthritis (OA) in the general population. Method: The screening questionnaire was based on signs and symptoms, previous diagnosis of OA, and validated OA criteria. A random sample of telephone numbers was obtained and, at each number, one individual aged 40 to 75 years was included. A physical examination and knee or hip radiographs were offered when the screen was positive. A sample of individuals with negative screens was also examined. The diagnosis of hip/knee OA was based on either American College of Rheumatology criteria for signs and symptoms and Kellgren-Lawrence radiographic stage 2 or greater. Prevalence rates were estimated with correction for the performance of the screening procedure.

The purpose of this prospective clinical data collection is to document the performance and clinical outcomes of the M2a- 38™ Hip System

The primary objective of the study is to determine how the short-term outcome of subjects implanted with the JOURNEY™ II BCS Total Knee System compares to subjects implanted with other PS total knee systems, and to determine if there is a difference in health care resources consumed that may result in economic savings to patients, the facility and/or the payer. To address the study objectives, patient self-assessment questionnaires, and other objective measures of post-operative function and health care resource utilization will be used for data collection.

The primary objective of this study is to evaluate the radiographic outcomes of Total Ankle Arthroplasty in patients having a calcaneal stem.

This study will compare changes in outcomes following viscosupplementation for knee osteoarthritis.

To evaluate the ConforMIS iDuo G2 implant

The purpose of this study is to compare range of motion, Knee Society Scores, and duration of surgery for different total knee prostheses.

This is an observation of the current use of a transdermal preparation of Celecoxib 8% which is being used in the treatment of patients with primary OA of the knees. Subjects will be followed for 12 weeks.

To assess the pain scores before and after saphenous nerve block placement in patients with degenerative joint disease of the ankle
