Abstract:
Objective To evaluate the short-term outcomes and analyze the complications of medial unicompartmental knee osteoarthritis (MUKOA) treated by unicompartmental knee arthroplasty (UKA).Methods Retrospectively analyzed the patients suffered with MUKOA and registered into our department from Jul 2015 to Jan 2017.71 cases were enrooled in the study,of which 17 are male (19 UKA) and 54 are female (66 UKA).The general information,perioperative data,Hospital for Special Surgery (HSS) score,visual analogue score (VAS) and complications of the group were analyzed.Results Females were three times more than males (54∶ 17).The average age of female subjects was lower than that of male,the difference was significant (P ＜ 0.05).The rate of Osteoporosis of females was significantly higher than that of males (P ＜ 0.05).The operative time,length of incision,total overt blood loss and postoperative in-bed time were (54.06 ± 6.24) min,(8.56 ± 0.83) cm,(86.10 ± 5.44) ml,(3.51 ± 1.01) d,respectively.No significant differences were found between males and females (P ＞ 0.05).The preoperative,3 months and 6 months postoperative HSS scores were 45.2 ± 4.5,80.3 ± 5.7 and 88.4 ± 4.2,respectively.No differences were found between males and females (P ＞ 0.05).The preoperative,3 months and 6 months postoperative VAS scores were 6.6 ± 1.2,1.7 ± 0.7 and 0.5 ± 0.5,respectively.No differences were found between males and females (P ＞ 0.05).There were 2 revised cases,and the reasons for revision were infection and unstability caused by sport injury.Conclusions UKA is an ideal choice for patients with MUKOA,Especially for the ones older than 60 years.However,the corrections on lower-limb forceline and joint unstability are limited,thus,the indications for UKA should be controlled strictly.
