Official Title: Prospective, Randomized Study of Highly-cross Linked Polyethylene vs. Compression Molded Polyethylene for Primary Posterior-stabilized Total Knee Arthroplasty
Brief Summary: Polyethylene wear and osteolysis remain a concern with the use of modular, fixed bearing total knee arthroplasty. A variety of highly cross-linked polyethylenes have been introduced to decrease this problem, but there is little data on the results and complications of this polyethylene in posterior-stabilized knee prosthesis. The investigators asked the following questions: (1) Are there any differences in the clinical and radiographic results when a highly cross-lined polyethylene is compared to a standard liner? (2) What is the frequency of reoperation in these two groups and are there any specific complications related to highly cross-linked polyethylene liners.
