This study is designed to compare prospectively, in a randomized Level 1 evidence fashion, the clinical, functional, and radiographic results of a modular polished tibial (MPT) tray with a moderately cross-linked polyethylene (XLK) insert to an all-polyethylene tibial (APT) design with GVF polyethylene. Comparing these two designs will afford us information in the following areas: 1. Does a MPT/XLK design have improved wear characteristics over a nonmodular APT/GVF ...
A post market, prospective, non-randomized, multi-center, open-label, clinical study using survivorship as the reference performance goal to study the safety and efficacy of the Titan Modular Shoulder System 2.5 when used for primary shoulder arthroplasty.
The purpose of this study is to demonstrate survivorship of the femoral stem at 5 years.
The primary objective of this study is to obtain implant survivorship and clinical outcomes data for commercially available Persona fixed bearing knee implants used in total knee arthroplasty. The assessment will include implant survivorship and clinical performance measured by pain and function, quality of life data, radiographic parameters and survivorship.
This clinical study will evaluate the early to midterm safety and performance of the JOURNEY™ II UNI UKS in patients with non-inflammatory degenerative joint disease of the knee requiring lateral or medial knee compartment replacement. Clinical, radiographic, health economic and safety outcomes will be evaluated.
This study will be designed to compare prospectively, in a randomized fashion, the clinical, functional, and radiographic results of a nonmodular (all-polyethylene tibi/AP) fixed-bearing posterior cruciate substituting design with a modular posterior cruciate substituting rotating platform (RP) design for total knee arthroplasty. Comparing these two designs will afford the investigators information in the following areas: 1. Does a RP design offer improvement in range of mo...
Vitamin E incorporated highly cross linked polyethylene (E-XLPE) was developed to increase oxidative resistance of highly cross-linked polyethylene (XLPE) without affecting mechanical properties. The investigators evaluated this type of polyethylene in a randomized clinical study, using Radiostereometric Analysis (RSA). The objective of this study was to compare the early-term wear of E-XLPE to a compression annealed polyethylene liner (C-XLPE, ArComXL®). The clinical outcome ...
SUMMARY A prospective, randomized, single-blinded clinical trial is proposed to compare three tibial tray designs for patients undergoing total knee arthroplasty. This study is designed to address the clinically important issues of tibial component modularity and fixation in total knee replacement. The Zimmer NexGen Legacy knee system is an FDA approved device and in this study will be used with 1) a modular tibial tray inserted with cement and 2) a non-modular tibial tray inse...
The purpose of this study is to evaluate long-term clinical and radiographic data between geometrically identical GVF and cross-linked polyethylene-bearing inserts in total knee arthroplasty.
The Importance of Different Modularity of the Polyethylene Insert for Tibial Component Migration and Adaptive Bone Remodeling After Uncemented Total Knee Arthroplasty Using Trabecular Metal Technology (TMT) Zimmer NexGen®, (Monoblock vs. Modular Design)
In a prospective randomised study two uncemented tibial components with different polyethylene modularities (Trabecular Metal Technology (TMT) Zimmer NexGen® monobloc and TMT Zimmer NexGen® modular) used for total knee arthroplasty (TKA) is evaluated. Both tibial component coatings are designed to provide excellent condition for bone ingrowth. The differences between the two tibial components are evaluated by measurements of migration of the tibial component assessed by Rad...
Study evaluates the efficacy and tolerability of low volume preparations compared with conventional 4L polyethylene glycol prior to colonoscopy
The purpose of the study is to determine whether crosslinked Marathon and standard Enduron polyethylene liners show differences in survivorship due to wear-related revisions at minimum 14-year follow-up and every 5 years after.
The aim of this study was to determine clinical and radiographic results after posterior cruciate-substituting total knee arthroplasties with highly cross-linked polyethylene in one knee and compression mold conventional polyethylene in the contralateral knee in the same patients.
Total hip arthroplasty (THA) is one of the most effective medical procedures. Except for the few early complications (acute infections and dislocations), the patient made a PTH can be assured of a significant improvement in its function and its short-term quality of life. However, clinical studies and records have shown that the lifetime of these implants was limited. The main cause of failure is the "aseptic loosening" influenced by many factors, foremost of which is due to pe...
This is a retrospective, multicenter case series with a prospective follow-up to confirm the safety and performance of the Gemini SL Fixed Bearing knee prosthesis in midterm follow-up under routine conditions. Primary outcome of the study is the 5-year survival rate of the Gemini SL Fixed Bearing knee prosthesis with revision for any reason as the end point.
The study will focus on survivorship care for head and neck cancer patients cared for within Duke Cancer Center clinics. Standardized survivorship care plans (sSCP) are being implemented based on the American Society for Clinical Oncology's criteria. These documents provide a summary of treatment received, and list side effects and follow-up information after cancer treatment. Taking advantage of this transition, the investigator will study three groups of patients: (a) early s...
Total replacement of hip joint is one of the most important medical innovations of the twentieth century. More than 100,000 hip replacements are being laid each year in France. Improved fixation, reduced wear rates and reduced implant dislocation rates remain subjects of continuous improvement. Hip implants cemented and cementless are part of therapeutic arsenal of orthopedic surgeons for joint replacement of the defective hip. The anchor and friction torque are both e...
The goals of total, reverse total and hemi shoulder arthroplasty are the same, to alleviate the patient's pain and obtain a full functional recovery. This outcome depends on the surgeon's ability to reproduce normal glenohumeral anatomy including bone morphology, capsular tension and rotator cuff function. Shoulder arthroplasty has become a safe and effective treatment for various diseases of the shoulder. This study goal is to document and report the short-term functional, rad...
The goal of this study is to study the stability of the Delta-TT cup with polyethylene insert and the Delta-TT cup with ceramic insert both combined with the H-MAX femoral stem by means of RSA to assess whether the differences in stiffness of the cup will have an influence on incorporation and mechanical stability. It is hypothesized that there will be more micromotion on the short-term (
30 Veterans who are full-time wheelchair users will use personalized modular cushions for two weeks each. Personalized cushions will be created using a cushion fitting process the investigators have already developed and tested. Microenvironmental conditions will be monitored during use. A cost analysis will ensure the customized modular cushion applies value-driven principles. User satisfaction will be measured along with the effects on daily function, skin status and seated t...
