Descriptive Information
Brief Title  ICMJE Effect of Cutting Blades for Total Knee Arthroplasty on Implant Migration
Official Title  ICMJE Effect of Cutting Blades for Total Knee Arthroplasty on Implant Migration. A Randomized Controlled Study With Radiostereometric Analysis
Brief Summary

There have been considerable efforts to control rising health care costs. One of the more recent developments is the practice of reprocessing single use medical devices. This practice has been shown to provide considerable savings for health care payers. Medical devices have been reprocessed in a number of different medical fields including Orthopaedic Surgery. One of the devices that has been reprocessed are the Precision Saw Blades from Stryker Inc. These saw blades are used during Total Knee Arthroplasty (TKA) surgery. The reprocessed Precision saw blades are Health Canada approved and are available at Capital Health.

Beyond the benefits to the environment and cost savings, the investigators do not know if the reprocessed saw blades work better, work worse or the same as non reprocessed saw blades. This study is designed to determine if the reprocessed saw blades used during a TKA work as well as a new saw blade.
