Abstract:

BACKGROUND: In the past, the main end-stage treatment of osteoarthritis was joint replacement surgery. In recent years, with the prevalence of the concept of knee-protection and the continuous development of internal fixation materials and surgical techniques, unicompartmental replacement, a minimally invasive technique, has been widely used in the treatment of patients with single-chamber osteoarthritis.

OBJECTIVE: To compare the efficacy of unicompartmental knee arthroplasty in osteoarthritis patients using robotic-assisted or traditional manual methods by meta-analysis systematically.
METHODS: We searched for clinical control studies published from 1999 to March 2019. The retrieved databases included Embase, PubMed, Central, Cinahl, PQDT, CNKI, CQVIP, Wanfang, Cochrane Library, CBM and other databases. Five outcomes including tibial component implantation accuracy, femoral component implantation accuracy, tibiofemoral component safety zone, operation time and complications were selected to compare the efficacy differences between robotic-assisted techniques and traditional manual methods systematically.
RESULTS AND CONCLUSION: (1) According to the above retrieval strategies, eight foreign literatures were included. (2) By comparison, we found that the robotic-assisted unicompartmental knee arthroplasty was superior to manual methods in the accuracy of tibial component placement [95%CI (-2.13, -0.63), P=0.000 3], femoral component placement [95%CI (-2.49, -0.32), P=0.01] and the tibiofemoral component safety zone [95%CI (1.05, 17.57), P=0.04] with significant statistical difference. (3) Although robotic assistant technology took longer operation time [95%CI (12.58, 42.33), P=0.000 3], it did not increase the incidence of complications [95%CI (0.75, 3.71), P=0.21]. (4) In unicompartmental replacement surgery, robotic assistant technology has higher accuracy and does not increase the incidence of complications. It is a more ideal surgical method than traditional manipulation. These conclusions need to be validated by a larger sample and a higher quality randomized controlled study.
