Compared with patients who underwent total knee replacement, patients who underwent unicompartmental knee replacement experienced a significantly higher risk of revision/reoperation, according to study results.
Investigators in the United Kingdom compared matched patients undergoing total knee replacement (TKR) and unicompartmental knee replacement (UKR) in the National Joint Registry for England and Wales and linked data for multiple potential confounders from the National Health Service Hospital Episode Statistics database. Regression models were used to compare outcomes, including rates of revision, revision/reoperation, complications, readmission, mortality and length of stay.
On the basis of propensity score, the investigators matched 25,334 UKRs to 75,996 TKRs. At eight years, study results showed a worse implant survival for both revision and revision/reoperation among patients who underwent UKRs vs. TKRs. However, mortality was significantly higher for TKR at all time points compared with UKR, according to the data.
Additionally, length of stay, complications and rate of readmission were all higher among patients who underwent TKR, the data showed.
