UKA associated with low mortality rate, postoperative complications
Patients who underwent unicompartmental knee arthroplasty had low complication rates as well as less morbidity and mortality in a 90-day postoperative period, according to these study results.
Researchers retrospectively reviewed 1,000 consecutive unicompartmental knee arthroplasties (UKA) in 828 patients. A retrospective review was also performed to evaluate 90-day perioperative complication and mortality rates.
Overall, researchers found no deaths while only 12% of the UKAs were complicated by variances within the 90-day postoperative period. One patient experienced deep venous thrombosis. Study results showed no pulmonary emboli and cardiovascular complications were reported as infrequent. Three patients had myocardial infarctions, one patient developed congestive heart failure, one patient had angina and three patients had arrhythmias.
During the follow-up period, secondary procedures were performed in 15 patients due to arthrofibrosis, arthroscopic removal of retained cement and drain, repeat wound closure after a dehiscence after a fall, ORIF for a supracondylar femur fracture, irrigation and debridement for aseptic hematoma and radical debridement for a periprosthetic infection with a later conversion to a total knee arthroplasty.
