Abstract:

BACKGROUND: There is a controversy on one-stage bilateral knee joint and unilateral knee joint replacement.
OBJECTIVE: To evaluate early clinical efficacy and SF-36 health survey differences on the patients with bilateral knee disease after bilateral knee joint replacement and selective unilateral knee joint replacement.
METHODS: A total of 144 patients (190 knees) were treated with bilateral knee joint replacement (bilateral group) and selective unilateral knee joint replacement (unilateral group), the prostheses were made by Smith & Nephew (GenesisTM ‖ smith & nephew). The range of motion, hospital for special surgery (HSS) score and visual analogous scale score, as well as the postoperative complications and postoperative SF-36 survey results were observed.
RESULTS AND CONCLUSION: After one-year follow-up, 9 cases were lost and 135 patients entered the final analysis. In the bilateral group, there was 1 case of transient peroneal nerve palsy, 1 case of acquired immunodeficiency syndrome and 1 case of poor wound healing; in unilateral group, there were 2 cases of poor wound healing. At 1 year after replacement, SF-36 survey results showed that there was a significant difference of physiological function between two groups (P < 0.05), and there was no significant difference of the other seven factors between two groups (P > 0.05); there was no significant difference of range of motion and HSS score between two groups (P > 0.05); the visual analogous scale score in the bilateral group was lower than that in the unilateral group (P < 0.05). Results show that the early visual analogous scale score in the bilateral group is lower than that in the unilateral group, however, there is no significant difference of the SF-36 survey, HSS score and range of motion between two groups.
