NCT ID: NCT02798432 Active, not recruiting - Clinical trials for Total Knee Arthroplasty

Hybrid Versus Cemented TKA Using the NexGen LPS Prosthesis

Start date: June 2015
Phase: N/A
Study type: Interventional

Early total knee arthroplasty (TKA) implant systems most frequently used an all-polyethylene cemented tibial component1. Based on finite-element analysis studies reporting superior force distribution compared with conventional all-polyethylene components, metal-backed tibial baseplates have dominated the TKA implant market since the middle of the 1980's2. These modular implants provided excellent long-term implant survivorship3. As TKA became increasingly successful, younger patients increasingly became eligible. Increasing life expectancy has raised the concern that cemented TKAs may not withstand prolonged use, particularly in younger patients4. Patients younger than 65 years are projected to account for more than 50% of patients undergoing TKA by 2016 and to more than 50% of patients undergoing revision surgery by 2011. The number of total knee revisions in the United States is expected to increase from 38,300 in 2005 to 268,200 in 20305. Many authors have reported excellent and equivalent results of cemented and cementless TKA6-8. Despite these encouraging reports, the major concern with cementless TKA has been the tibial component, and, therefore, the preference for many surgeons still remains to cement the tibial component9,10. The femoral component may be the most suitable for cementless fixation11-13. However, the best femoral method of fixation is still being discussed. Currently, the decision to cement or not to cement the femoral component is based on the surgeon's preference14. The current study was designed to compare the hybrid NexGen LPS (Zimmer Inc, Warsaw, IN) and the cemented NexGen LPS. The purpose of this study is to establish whether the hybrid NexGen LPS leads to equally successful results as the cemented TKA gold standard

Why Are so Many Patients Dissatisfied With Knee Replacement Surgery? Exploring Variations of the Patient Experience

Start date: November 2011
Phase: N/A
Study type: Observational

The goal of this research is to fill the knowledge gap relating to why up to 20 percent of total knee arthroplasty (TKA) patients are dissatisfied with their clinical outcomes and to answer the research question: What are the drivers of variation in the patient experience with primary (ie. not revision) TKA?

NCT ID: NCT00712816 Active, not recruiting - Osteoarthritis Clinical Trials

Use of Cold and Compression Therapy With Total Knee Replacement Patients

Start date: July 2008
Phase: Phase 4
Study type: Interventional

The purpose of the study is to evaluate the effectiveness of a device that delivers cold and intermittent compression as compared to ice and compressive wraps on patients who have undergone knee replacement.
