Polyethylene

Published results showed isolated polyethylene exchange was less reliable and durable compared with full component revision for patients with instability after total knee arthroplasty and should only be reserved for specific cases.

LOUISVILLE, Ky. — Data showed carbon fiber insoles and polyethylene shoe insoles were associated with improved patient-reported pain scores in patients with plantar fasciitis.

Exactech has announced FDA 510(k) clearance of its Activit-E knee polyethylene for total knee replacement surgery, according to a press release.

WAIKOLOA, Hawaii — Late osteolysis may still be a concern for patients undergoing total hip arthroplasty with highly crosslinked polyethylene, despite notable reductions in wear and improved survivorship, a speaker said.

According to an FDA safety communication, all Scandinavian Total Ankle Replacement devices – known as the STAR Ankle from Stryker – had a higher-than-expected risk of polyethylene component fracture.

Published results showed ceramicized metal-on-crosslinked polyethylene and ceramic-on-crosslinked polyethylene bearing surfaces used in total hip arthroplasty yielded the lowest risk of revision for any reason.

Results showed use of an all-polyethylene tibial component in total knee arthroplasty may significantly lower surgical and total hospital admission costs while maintaining equivalent 90-day outcomes compared with metal-backed components.

Despite no notable differences in hip function or pain in patients who underwent total hip arthroplasty, vitamin E-diffused polyethylene liners had “significantly less liner wear” than crosslinked polyethylene liners at 7-year follow-up.

Patients who underwent total hip arthroplasty with ceramic-on-polyethylene implants had a higher risk of revision compared with those who had metal-on-polyethylene implants, according to results presented at the Virtual EFORT Congress.

Published results showed use of ceramicized metal-on-crosslinked polyethylene and ceramic-on-crosslinked polyethylene bearing surfaces during total hip arthroplasty yielded the lowest risk of revision for any reason.
