45 active trials for Total Knee Arthroplasty

IPACK Block in Total Knee Arthroplasty

100 patients ASA I-III, undergoing total knee arthroplasty under spinal anesthesia, will be randomly assigned into one of two groups, namely group A (n=50), where an adductor canal block and an IPACK block will be performed preoperatively and group B (n=50) where an adductor canal block only will be performed preoperatively. All patients will receive a standardized multimodal approach, including pregabalin, paracetamol, and PCA with morphine. NRS scores in static and dynamic conditions during the first 48 hours postoperatively, morphine consumption during the first 24 hours postoperatively will be measured and additionally, patient satisfaction, complications, range of knee motion, moblization, functionality, delirium ocurence will be recorded. Chronic pain will be assessed in 3 and 6 months postoperatively.

Start: October 2018

Comparing Surgical and Economical Parameters of Total Knee Replacement.

Randomized study comparing surgical and economic parameter of Total Knee Arthroplasty performed using two different specific surgical techniques.

Start: August 2018

Navio With Total Knee Arthroplasty

The purpose of this study is to demonstrate superior accuracy with the Navio ™ Robotic-assisted Surgical System in achieving desired post-operative mechanical alignment, compared to TKA procedures using standard instruments. An additional study purpose is to document clinical and patient-reported outcomes in subjects receiving TKA with the Navio ™ system.

Start: October 2017

The Efficacy of Using CR and PS Prosthesis in Total Knee Replacement

The investigators will investigate the efficacy of using CR and PS implants in TKA. The investigators will conduct TKA with different implants simultaneously on one patient to compare the post-operation efficacy of both implants.

Start: December 2018

Hybrid Versus Cemented TKA Using the NexGen LPS Prosthesis

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
