[Clinical results and peri-operative complications of total knee arthroplasty for patients with different ages].
OBJECTIVE
To analyze the clinical results and complications of total knee arthroplasty (TKA) performed for patients with different ages.


METHODS
From January 2004 to March 2005,212 patients (300 knees) were followed up, all patients were divided into 6 groups according to the age. All the complications and knee society scores (KSS) were documented and retrieved for analysis.


RESULTS
KSS of all groups was significantly improved after TKA. The patients whose age was 70 years or older, and underwent bilateral TKA achieved the best improvement of knee function. The complication rate increased with the patients' age.


CONCLUSIONS
TKA predictably alleviates knee pain and restores knee function. Aging itself does not compromise clinical results of TKA. However perioperative complication rate is a little bit higher in aged patient group and simultaneously bilateral TKA patient group.
