Medium-term outcomes of MAKO robot-assisted medial unicompartmental knee arthroplasty
Objective:To evaluate the medium-term clinical outcomes of MAKO robot-assisted medial unicompartmental knee arthroplasty(UKA).Methods:A retrospective analysis was performed on patients underwent MAKO robot-assisted UKA from January 2016 to December 2018.Totally 28 patients with the mean age of(62.6±7.5)years(range,51-74 years)were included and there were 6 males and 22 females.The mean score of the body mass index(BMI)was(26.2±3.3)kg/m2(range,19.5-32.0 kg/m2).The imaging finding and joint function were evaluated during the follow up,and the complications were observed.The rate of in-place prosthesis and angular deviation of the prosthesis were analyzed with imaging.The evaluation of joint function included Oxford knee score(OKS),knee society score(KSS),the satisfaction of the patients and forgotten joint score(FJS).Results:All patients were followed up with a mean duration of(51.1±6.0)months(range,44-59 months).All prosthesis in 33 knees were alive and in place,and no abnormal angular deviation of the prosthesis was observed compared with that one year after the operation.KSS and OKS were significantly improved compared with pre-operation and one year after the operation with no significant difference(P>0.05)at the final follow-up.The mean satisfaction score was(35.0±1.9)points,and the mean FJS was(89.2±2.9)points at the final follow-up.Three patients reported complications including 2 patients with anterior knee pain and one patient with lateral knee pain.Conclusions:In medium-term follow-up of MAKO robot-assisted UKA,the prosthesis orientation outliers are not observed.Joint function and patient reported outcome measurements are excellent.MAKO robot-assisted UKA achieves satisfied clinical outcomes.
