The influence of prior arthroscopy on subsequent total knee arthroplasty: the comparison in the same patient

Abstract

Background: To explore whether prior arthroscopic knee surgery affects future total knee arthroplasty or not Methods : A total of 36 patients with prior arthroscopy who underwent total knee arthroplasty in the department of orthopedics, affiliated hospital of Qingdao University from September 2013 to July 2017 were collected. We defined the knee with a prior arthroscopy history as group A, and the other side as group B. Using Kolmogorov-Smirnov test to test normality of continuous variables, and the chi-square test was applied to compare the rate of reoperation and complication between two groups. For all statistical comparisons, P<0.05 was considered significant. Results: There was no statistical significance in postoperative Knee Society clinical score and functional score between group A and group B, as well as ROM, FJS, VAS scores and local complications Conclusion : There were no statistically significant differences in postoperative functional recovery and complications in patients who underwent total knee arthroplasty with prior knee arthroscopy.
