RESUMO
Objective:To observe the postoperative complications and revision rates of robot arm-assisted unicompartment arthroplasty by means of a meta-analysis.Methods:Relevant databases including Cochrane Library, PubMed, EMBASE, Wanfang, VIP, CNKI, and Web of Science were searched by computer for high-quality studies on complications and revision rates after robot arm-assisted unicompartment arthroplasty in both English and Chinese from the database establishment date to March 2021. The quality of the studies retrieved was evaluated. Relevant data including postoperative complications, infection, pain, prosthesis loosening, and revision were extracted for a meta-analysis using STATA 15.0 software.Results:A total of 16 studies were included, including one randomized controlled study, 6 case-control studies and 9 cohort studies. By the methodological index for non-randomized studies (MINORS), 7 studies scored 14 points, 3 studies 13 points, one study 12 points, 4 studies 11 points, and one study 10 points. Meta analysis showed that the total rate of complications was 2% (95% CI: 1%to 4%) . Three studies used NAVIO robot, 7 studies MAKO robot, one study NAVIO and MAKO robots, and one study Acrobot robot. Since just one study used Acrobot robot, only MAKO and NAVIO robots were included for the subgroup analysis which showed that the postoperative complication rates for NAVIO and MAKO robots were 4.0% (95% CI: -2% to 10%) and 3% (95% CI: 1% to 5%) , respectively. The incidence of postoperative pain was 0.2% (95% CI: 0.1% to 0.3%), the incidence of postoperative infection 0.5% (95% CI: 0.3% to 0.8%), the incidence of postoperative prosthesis loosening 0.5% (95% CI: 0.3% to 0.8%), and the revision rate 2% (95% CI: 1% to 2%). According to the subgroup analysis of NAVIO and MAKO robots, their revision rates were 4% (95% CI: 2% to 7%) and 2% (95% CI: 1% to 2%), respectively. Conclusion:The clinical efficacy of robot arm-assisted unicompartment arthroplasty is good, for the complications in the patients are limited and the long-term survival rate of the prosthesis is excellent.
RESUMO
Posterior tibial slope (PTS) is used to describe the sagittal alignment of the tibial plateau of the knee.As its values indicate the steepness or gentleness of the tibial platform,it is an important basis for knee surgery,such as total knee replacement (TKA),anterior cruciate ligament/posterior cruciate ligament reconstruction (RACL/RPCL) and tibia high-level osteotomy (HTO),and affects the indication and efficacy of knee surgery.Since there has been no consensus description of PTS at present in clinical practice in China,this paper intends to discuss PTS from perspectives of epidemiology,measurement,its influence on knee joint activity,relationship between subchondral bone and knee ligament,and its significance in various knee joint operations.This review hopes to contribute to the knee surgery after the surgeons have a comprehensive understanding of the clinical significance and applications of PTS.

RESUMO
The distal radioulnar joint (DRUJ) is one of the most important joints connecting hand and forearm,playing an important role in maintaining normal rotation of the hand and forearm and stability of the wrist.Serious DRUJ dislocation can lead to functional limitation of the forearm and wrist.DRUJ displacement is not uncommon clinically,but often missed.It is usually associated with a distal radioulnar fracture,with an incidence ranging from 10％ to 19％.Without correct and effective diagnosis and treatment,it will lead to chronic pain,dysfunction and other complications.There are various treatments for DRUJ displacement,like initiative splint fixation,percutaneous fixation with kirschner wire,soft tissue reconstruction,joint fusion and joint replacement at the end-stage,and arthroscopic techniques as well which are increasingly popular in recent years.All these treatments ease the patients' pain to a certain extent,but also bring about complications of different severities.Currently,reconstruction of the DRUJ stability using elastic suspension system may be a new treatment alternative in the future because it has gradually attracted the attention from experts.
