Patella

DALLAS —Patients who did not have patella resurfacing at the time of total knee arthroplasty had increased revision rates, according to data presented at the American Association of Hip and Knee Surgeons Annual Meeting.

Results showed patients who underwent total knee arthroplasty and routine patellar resurfacing with a cemented biconvex all-polyethylene inlay component had excellent survivorship and low rates of complications at 15-year follow-up.

SAN FRANCISCO — Results presented here showed replacing the patellar component in stage-one revision total knee arthroplasty may improve outcomes in patients with a periprosthetic joint infection.

Compared with patients with normal patellar height, patients with patella alta demonstrated less severe cartilage damage and a lower frequency of full-thickness defects after patellar instability, according to published results.

KOLOA, Hawaii — In this video from Orthopedics Today Hawaii, Andrew Shimmin, MBBS, FRACS, spoke about several technical aspects of resurfacing the patella during total knee replacement despite the lack of available technology.

KOLOA, Hawaii — In this video from Orthopedics Today Hawaii, Richard W. McCalden, MD, spoke about routinely resurfacing the patella when performing total knee replacement.

Since describing anteromedialization tibial tubercle osteotomy for realignment and unloading of the patella in 1983, indications have changed.

Published results showed a 93.3% survivorship free from any aseptic patellar complication at 20 years in patients who underwent total knee arthroplasty with a cemented all-polyethylene patellar component.

WAILEA, Hawaii — In this video from Orthopedics Today Hawaii 2021, Cory A. Collinge, MD, spoke about tibial nailing through the suprapatellar portal.

Published results showed knees with and without patellar instability had highly variable patellar morphology, as well as minimal association between measurements of patellar morphology and trochlear dysplasia.
