Abstract:

BACKGROUND: Most of the patients with bilateral knee osteoarthritis will not receive the contralateral total knee arthroplasty due to many factors.
OBJECTIVE: To analyze the factors for the bilateral knee osteoarthritis patients undergoing a selective unilateral total knee arthroplasty without contralateral knee arthroplasty at second stage.
METHODS: A toal of 28 bilateral knee osteoarthritis patients (28 knees) treated with unilateral total knee arthroplasty were included, the prostheses were the Smith & Nephew ordinary type. All the patients did not receive the second stage contralateral knee arthroplasty within 1 year after unilateral total knee arthroplasty. The HSS score and range of motion of knee were recorded before and after replacement; at the same time, the 28 patients that did not receive the second stage contralateral knee arthroplasty were questionnaired for the factors.
RESULTS AND CONCLUSION: Two cases were lost, 2 cases underwent contralateral total knee arthroplasty at the other hospital. And finally, 24 patients (24 knees) received the final follow-up, the average follow-up time was 12.6 months (12 to19 months). The range of motion and the HSS score after replacement were improved compared with those before replacement, the difference was statistically significant (P=0.007, P=0.409). Questionnaire survey was performed to analyze the factors for second stage surgery, single factor follow-up results showed that perioperative pain was the main reason that accounting for more than 95%; multivariate follow-up results showed that perioperative pain accounted for 95.8%, psychological factors accounted for 87.5%, conditions of the hospital's software accounted for 70.8%; the average of the three reasons accounted for 84.7%. It indicates that perioperative pain, psychological factors and conditions of the hospital's software are the dominate reasons for the 24 patients (24 knees) without second stage ontralateral knee arthroplasty.
