title: 5- to 16-year follow-up of 54 consecutive lateral unicondylar knee arthroplasties with a fixed-all polyethylene bearing.
abstract: The clinical and radiographic results of 54 knees (52 patients) with a unicondylar knee arthroplasty (UKA) with fixed-all polyethylene bearing implanted for lateral osteoarthritis were studied at 5- to 16-year follow-up (mean, 100.9 months). Four underwent second surgery: 1 conversion to total knee arthroplasty and 3 received UKA in the medial compartment. The mean International Knee Society knee score was 94.9 points, with a mean range of motion of 132.6° and a mean International Knee Society function score totaling 81.8 points. Implant survival was 98.08% at 10 years. These excellent results suggest that UKA with fixed-all polyethylene bearing is a reliable option for management of isolated lateral knee osteoarthritis.
