ABSTRACT
PURPOSE: The purpose of this study was to evaluate the clinical effect of electrocautery on the reduction of pain in patellar non-resurfacing bilateral total knee arthroplasty. MATERIALS AND METHODS: A total of 50 patients were enrolled into this study; all patients had undergone bilateral patellar non-resurfacing total knee arthoplasty at our hospital, between January 2007 to December 2008. The minimum follow-up period was 1 year. The electrocautery of the patellar rim was performed randomly on one side only. The clinical results were evaluated between the electrocautery group and the non-electrocautery group based on measures of anterior knee pain, range of motion, American Knee Society clinical rating score, Feller knee score, Western Ontario and McMaster Universities score, and radiographic analysis. RESULTS: There were statistically significant differences between preoperative and postoperative status for all parameters. There were no statistically significant differences noted between the electrocautery group and the non electrocautery group for all parameters. CONCLUSIONS: Electrocautery of patellar rim is thought to be less effective in reducing anterior knee pain.
ABSTRACT
Total ankle arthroplasty is a commonly performed invasive procedure that can be distressing to patients. Therefore, surgeons should consider patients' issues of greatest interest and concerns at the time of surgery and the function that patients hope to recover. Many studies have reported surgeon concerns before total knee arthroplasty and total hip arthroplasty, but few have focused on patients. The purpose of this study was to evaluate patients' functional disabilities and issues of concern regarding total ankle arthroplasty.Between May 2008 and June 2010, eighty-five patients (52 men and 33 women; mean age, 60 years) were recruited for the study. All patients were asked to complete a questionnaire divided into 3 parts: sociodemographic data, current functional disabilities and their perceived importance, and issues concerning patients before total ankle arthroplasty. Regarding functional disability based on severity, the top 5 issues were limping, difficulty squatting, daytime pain, difficulty kneeling, and difficulty climbing stairs. Regarding functional disability based on perceived importance, the top 5 issues were daytime pain, limping, difficulty walking, difficulty kneeling, and difficulty working. Regarding issues of concern, the top 5 issues were pain intraoperatively, ability to walk as much as desired, ability to climb stairs, pain after discharge from the hospital, and pain immediately postoperatively. The most important issue before total ankle arthroplasty was pain. Patients had a strong interest in high ankle extension and increased range of motion due to the lifestyle and religious activities of Eastern populations.
